cooling

We have been trying to optimize cooling for centuries. My grandfather from Toledo solved the heat with the simplest invention: a door split in two

by

He looks at me and says: “broken doors.” In his country house, my grandfather’s door opens in half: bottom leaf, top leaf, each with its own hinge. Every time I see it I think of cowboy movies, the logo of saloon from some after-dinner western. I imagined: “of course, for the cat.” Nothing to see. history class. The idea of ​​the split door is not only from La Mancha or Toledo, it is the same principle as the Dutch doors or stable doors from four centuries ago. According to the definition itself, the first dutch doors They date from the mid-17th century, around period 1640-1650. From here they became a practical solution in farms and rural houses in the Netherlands and the United Kingdom, in order to let air and light in while keeping out animals, dust and some of the cold. The chronology itself can be found in Dutch paintings of the time, such as ‘Young Woman at a Dutch Door’, from 1645 and attributed to Samuel van Hoogstraten, a painter in Rembrandt’s workshop. Its use became popular in the American colonial era and its fame decreased towards the end of the 18th century, in favor of more robust, secure and single-leaf doors. A tunnel of cold and cleanliness. At that time, the word air conditioning did not exist, but there was a concern for hygiene: when you open only the upper half, the door works like a large window, releasing pollution from cooking smoke, which, being less dense, always accumulates at the top. And thus a small renewal current was created with the lower leaf closed. If the house had another opening on the opposite façade, the effect was amplified: cross ventilation is generated that brings in cooler air on one side while hot air leaves on the other. A simple but very effective formula if activated first thing in the morning or in the late afternoon, when the sun sets. And in winter? Well, the same door allows the opposite: opening only the lower part for a few minutes to ventilate without the entire pocket of hot air stuck to the ceiling escaping, reducing thermal losses in houses without modern insulation and where the heat was produced from braziersglories (under the floor) or low chimneys. In winter you open the bottom part to ventilate without losing the warmth that gets trapped on top. In summer, quite the opposite: you open the upper part so that the hot air can escape while the ground floor remains in darkness. If you light a fire in the kitchen, just open the top so that the smoke comes out through natural convection —chimney effect pure and hard—while the lower leaf continues to act as a barrier against the cold that comes from outside, usually the corral or the orchard. Thick walls, slow summers. The split door works because it works in tandem with another ancient technology: fat walls. So thick that they do not allow the electromagnetic radio waves that make WiFi to work. In the traditional architecture of the Meseta it is not uncommon to find enclosures more than fifty centimeters thick, chambers made of stone, rammed earth or solid brick, with a thermal inertia similar to that of a cave. The physics behind it couldn’t be simpler: the more mass the wall has, the longer it takes the outside heat to pass through it. Meanwhile, the interior remains relatively cool, as happens in any church where the sun takes hours to show itself or sometimes not even that. The same wall, in winter, absorbs part of the heat from braziers and stoves and slowly releases it when night falls, reducing thermal fluctuations in homes without radiators. What we call today “passive comfort management” is this very thing. And without IoT sensors or apps. Grandparents know it all. Silos: fresh but dry. The third lesson is taught to us silos and traditional barns. To store grain, a dry and cold microclimate must be created, in order to stop fungi, bacteria and insects that can rot the grain. When the grain is wet, the dough breathes, generates heat and creates pockets where the temperature rises and moisture condenses; If there is no ventilation, the pile becomes a breeding ground that can ruin tons of harvest. The solution is as simple as creating aeration ramps at the base and airlocks – small windows – along the walls that allow air to travel through the bulk, equalizing temperatures and removing steam upwards. It is the chimney effect but on the contrary: if you leave the ventilation openings open, the hot outside air enters through these ducts, rises through the mass of grain and heats it from within, forcing the openings to be sealed well once the cereal is dry and cold. Domestic science, with convection c. This whole repertoire of split doors, thick walls, and silos with eyes works because it takes advantage of three basic ideas of fluid physics: hot air rises, cold air falls, and air moves from areas of higher pressure to areas of lower pressure. End. The cross ventilation —that is, opening opposite openings so that air crosses the home—relies on pressure differences between facades and the orientation of the wind, while the chimney effect uses vertical corridors (patios, stairs, door openings) so that hot air rises and sucks in cooler air from below. In research On traditional patio houses, it has been measured how two patios with different temperatures activate a convection current that keeps the main rooms within comfortable ranges, without a single air conditioning machine. Each and every passive ventilation strategy involves some cooling, because “convection helps dissipate the heat accumulated inside as long as the openings and volumes are well thought out.” In the end, my grandfather’s split door didn’t hack anything, it was just properly installed. Two hundred years ago there were no engineers INTA in San Pablo de los Montes or in Quintanar de la Orden, but there were people with heat … Read more

We have been cooling homes for decades with increasingly expensive machines. The Persian method has not consumed a single watt for 2,500 years

by

For decades, air conditioning has been the great response to heat. The more the temperatures rose, the more powerful the machine we installed was. However, more than 2,500 years ago, in a city in the Iranian desert, someone proposed an idea completely different: Maybe the problem was not how to cool a house, but how to build it so that it never got too hot. The heat has a new enemy. The planet is going through an escalation of unprecedented temperatures and the buildings are starting to pay the bill. Glass facades turn offices and homes into veritable greenhouses, concrete accumulates heat for hours and cities radiate energy at night. absorbed during the day. The consequence is an increasing dependence on air conditioning. According to the United Nations Environment Programme, cooling systems already consume about 20% of all the world’s electricity, a figure that will continue to grow as heat waves become more frequent. The Persian redesign. In the heart of the Iranian plateau is Yazda city where summer temperatures easily exceed 40 ºC and where survival was never a question of comfort, but engineering. There appeared one of the most sophisticated passive cooling systems ever conceived: he badgirknown as a wind catcher. His approach was radically different from the current one. Instead of combating the heat once it had entered the house, the architecture itself took care of it. to capture the fresh airexpel the heat and maintain a habitable interior without consuming electricity. Yazd The “Persian method”: a way of thinking. At first glance, a badgir It looks like a tall, decorative chimney jutting out from the rooftops. In reality, it is a carefully calculated system to take advantage of two natural phenomena. On the one hand, it captures the air currents that circulate several meters above the ground and channels them towards the interior. On the other hand, even when the wind hardly blows, it acts as a solar chimney: Hot air rises through the tower and, as it escapes, creates a depression that draws cooler air into the building. In many homes, this flow also passed over underground water tanks or connected channels. to the qanatsfurther increasing the cooling effect. A bâdgir in Yazd A city designed for the climate. The truly extraordinary thing about Yazd is that the badgir It did not work in isolation. It was part of an architectural ecosystem where each element fulfilled a function. The thick adobe walls slowly absorbed the heat. The inner courtyards they created microclimates protected from the sun. The qanats They transported groundwater from the mountains and helped cool the air. There were even the yakhchalenormous structures capable of manufacturing and preserving ice for months in the middle of the desert. The result was a city designed to work with the climate, not against it. Yakhchal in Yazd And the air conditioning arrived. During the 20th century, much of the Middle East and other warm regions embraced imported architectural models that had little to do with their climatic conditions. Concrete replaced adobe, glass facades replaced solid walls and passive solutions were giving way. to mechanical systems. Many badgir they were abandoned due to the lack of maintenance, due to the entry of dust or insects and, above all, because the air conditioning offered an immediate response. The problem is that it also moved energy consumption to the center of the equation and made cooling a permanent necessity. The irony of the West. As many wind towers fell into disuse in Iran, their principles were beginning to reappear discreetly in other parts of the world. Between the end of the seventies and the mid-nineties, thousands of modern versions of wind sensors in British public buildings. Shopping centers, hospitals and schools incorporated ventilation systems inspired by those ancient designs. In the United States, the Zion National Park visitor center was able to drastically reduce the need for air conditioning thanks to passive cooling strategies based on the same concept. Today architects and engineers they resort to simulations by computer to optimize a technology that was born centuries ago simply by observing how the wind moved. The future may not be in more efficient machines. Contemporary architecture begins to take on an idea that for decades was relegated to the background: the building is also part of the air conditioning system. Recent regulations in countries like uk They prioritize shade, natural ventilation and reduction of solar gain before resorting to mechanical solutions. Exterior blinds, slats, vegetal covers, materials with high thermal inertia or patios return to gain prominence. Even those who defend the use of air conditioning agree that these measures can significantly reduce energy consumption. The big lesson: don’t repeat the same mistake. The history of the Persian method and its badgir It does not prove that we should give up air conditioning. prove something much more uncomfortable: For decades we have tried to solve heat by adding machines to buildings that, in many cases, were designed as if the climate did not matter. The Persians followed the opposite way more than two millennia ago. Before thinking about how to cool a house, they thought about how to build one that needed to be cooled as little as possible. Perhaps the most revolutionary technology to face the next heat waves is not a new machine, but recover an old idea that had been waiting for centuries on the rooftops of the desert.

We believed that air conditioning was the only way to beat the heat. A Mexican architect has been cooling houses with paint for decades

by

In 1973, during the oil crisismany countries suddenly discovered that cooling buildings had become an energetic luxury. Bioclimatic architecture then returned to the center of the debate and many looked to old solutions: patios, thick walls, shade and cross ventilation. Curiously, decades before, an architect had already built houses following that logic, obsessed with something that today sounds strangely modern: that a home should offer serenity and refuge from the aggressiveness of the outside. Heat also enters through the eyes. For decades we have assumed that fighting the heat at home involves a almost automatic gesture: lower blinds and turn on the air conditioning. It is a mechanical, direct and, above all, solution. face. Long before that became the norm, the architect Luis Barragan Another idea was already working in Mexico City: that the temperature of a house does not depend only on its degrees, but on how the body perceives it. Its architecture, built between pink, yellow, blue walls and dense shadows, had spent decades exploring something that neuroarchitecture is beginning to support today: color, light and matter. alter physical sensation of space. They don’t cool the air, but they can cool the experience. House-Workshop of Luis Barragán Barragán understood the importance of color. In the Barragán’s workcolor was never decoration. Studies on his architecture show that he treated it the same as a wall or a window: as a structural tool of perception. Its pink, ocher or blue surfaces were designed to react to changing light of the day, transforming the depth, closeness and visual temperature of the space. A pink wall under the intense Mexican sun seems to radiate heat, while a deep blue patio prolongs the feeling of sky and distance. That rrelationship between color and light It was a central part of his work. The architecture moved with the sun, and with it the sensation of the inhabitant also changed. House-Workshop of Luis Barragán The house as a sensory laboratory. His best example remains the Luis Barragán Studio Housebuilt in 1948 and today protected by UNESCO. There everything is designed to modulate the bodily experience: thick walls, closed patios, interior gardens, water, darkness and color. UNESCO stands out precisely that deep dialogue between light, space and matter as one of the great contributions of the 20th century. The house is almost a manifesto of how a home can appeal to all the senses at the same time. Barragán saw it as a living organism, constantly evolving, and in that organism comfort did not depend on technology, but on balance. nterior of the Gilardi House, in Mexico City The half light as a refuge. Barragan distrusted of modern glass architecture and total transparency. While much of the 20th century celebrated large windows and abundant light, he argued for the opposite: the “half light”. He believed that human beings need spaces with shade and darkness to rest, think and concentrate. He said that too much light generates anxiety. In their houses, the windows are reduced, hidden or filtered with colored glass. The light never enters all at once; is dosed. This decision not only changes the emotional atmosphere, it also reduces the thermal load and softens the visual harshness of summer. It is an old and simple solution, almost forgotten in many contemporary homes. Patio of Barragan’s studio house The colors of the weather. The famous Barragán palette It did not come from an abstract theory. Its colors were born of the Mexican landscape. The pink of the bougainvillea, the red of the tabachin, the violet of the jacarandas, the ocher of the earth and the blue of the sky. Everything was part of a natural continuity between architecture and environment. In fact, the call “Mexican pink”developed together with the artist Jesús Reyes, became one of his most recognizable signatures. That color, present at the entrance to his studio or in patios like those of the Gilardi Housegenerates a feeling of calm and depth that continues to surprise those who visit it. Its architecture demonstrates that color can be an emotional regulator of space. Eduardo Prieto Lopez House Tradition already knew this trick. In reality, Barragán did not invent all this from scratch. Much of his work includes centuries of vernacular architecture in Latin America. Painted stucco houses, interior patios, thick walls and breathable materials were part of a climatic logic before electricity. Stucco, for example, allowed the walls they will breathe better in hot climates. Painting them prevented the glare of the white surfaces under the harsh sun. In many places, color not only gave identity, it also helped to better inhabit the heat. Barragán took that tradition and brought it to modern language. San Cristobal block Science explains it. Yes, because recent studies about emotional architecture and embodied perception help put words to what Barragán intuited. Today we know that light regulates circadian rhythms, affects mood and modifies thermal perception. We also know that certain colors can make a room feel cooler or warmer without changing its real temperature. The body first processes a sensory impression and then translates it into comfort or discomfort. Barragán worked precisely on that point. He designed spaces where perception and physiology intersected. An old idea for a new problem. Thus, in the era of air conditioning and skyrocketing thermometers, when cities overheat and energy consumption skyrockets every summer, Barragán’s architecture returns to read with other eyes. Their houses remind us that cooling does not always mean cooling the air. Sometimes means control the light, tame the shadow, reduce glass, use appropriate materials and choose a color well. Are slow solutionssilent and long before modern domestic technology. In that sense, his work seems less like an aesthetic relic and more like an open conversation with the present.

With the heat in Andalusia, my PC is crying out for a new cooling system. These are the ones I like the most

by

It’s not June yet, but it’s already hot. Inside my apartment, since the sun is shining all day, it is very noticeable. This, of course, doesn’t help my PC, which starts making a hell of a noise because of the air cooler I have mounted. I wanted to change the box alonebut it will also fall a new cooling for the processor: this one from Corsair that is discounted to 91.99 euros. CORSAIR Nautilus 360 RS Liquid CPU Cooling – 360mm AIO – Low Noise – Direct Connection to Motherboard – Intel LGA 1851/1700, AMD AM5/AM4 – 3X RS120 Fans Included – Black The price could vary. We earn commission from these links Easy-to-install liquid cooling without lights There are several reasons to choose this Corsair cooling. The first of them is that I have several things from this brand at home and they all work great for me. The price is also quite attractive, because although we have had it cheaper on other occasions, right now it has a discount that makes it a very interesting quality-price option. Especially if, like me, You don’t want it to have those additions that increase the price (RGB lighting, I’m looking at you). I search an AIO liquid cooling (that is, not a personalized one, which is very expensive) that is simple and does its job very well. This Corsair Nautilus fits there very well because it has a 360 millimeter radiator with three 120 millimeter fans eachso we can expect very good cooling for the PC CPU. Another key thing for me is that it makes little noise and it does not exceed 20 dBA, although the speed of the fans is adjusted depending on what your PC needs at all times. It’s easy to install and is compatible with both AMD and Intel processors, making it suitable for almost any user. It does not have RGB lighting or a screen in the pump areabut I think that’s great: they are additions that are good, but they make the product more expensive. There are other options within the Corsair catalog and from other manufacturers, but quality-price, I think this Nautilus is one of the best we can buy right now. Other liquid cooling that is on sale CORSAIR iCUE Link Titan 240 RX LCD Liquid CPU Cooling – FlowDrive Cooling Engine – Intel LGA 1851/1700, AMD AM5/AM4 – 2X RX120 RGB Fans – iCUE Link Hub Included – White The price could vary.

Liquid cooling or air cooler? What to choose so that your CPU doesn’t smoke without having to spend a fortune

by

How difficult it is to choose the parts of a desktop PC: what if the processor, what if RAM memory (well, if you find it at a good price), what if graphics card and other things. But it’s not all about your computer being as powerful as a NASA computer: you also have to design it so that it doesn’t smoke. And that’s where refrigeration comes in, a topic that has more to it than it seems and that we are going to explain in this article. Essentially, you have two ways to cool your processor: an air cooler and liquid cooling. You may read in many places that the latter is the best, but there are many nuances in that statement that must be clarified. So, let’s get down to business. Choosing an air cooler Let’s start with the air heatsink, which we can say is the ‘old-fashioned’ solution for cooling a processor. If you take a look at one of these heatsinks, you will see that it is almost all a fan, although it is a somewhat more complex component than that. Everything is placed on top of the processor and right there, depending on the model we choose, we must keep one thing in mind: may need a lot of space inside the PC case. Piecemeal. The air sink has a copper or aluminum base that rests just above the processor and, to facilitate heat transfer, the thermal pastea compound that makes it easier for this generated heat to pass from one place to another. That heat travels through heat pipes or heat pipes, which are sealed tubes with a small liquid inside that continuously evaporates and condenses to transport heat very efficiently, until it reaches the radiator. How does one of these heatsinks cool? There is no universal answer to this, since each model is different. But, yes, keep this: a quality air heatsink can cool better than small or medium liquid cooling. And that, in addition, with several very interesting advantages. The first thing is that these heatsinks are much easier to install: just apply thermal paste, screw and connect to the motherboard, nothing more. Besides, andThese heatsinks are much simpler and more durable. Basically, what can end up breaking is the fan and it is not difficult to replace at all. Now let’s get to the bad. Again, it will depend a lot on the model we choose, but there are air heatsinks that, when put at full capacity, They are real turbines and they make a lot of noise. They also take up a lot of space, as we said above, which has two implications. First, you need physical space to put it in the box. And second, if it fits just right, it will not have enough space to expel air and the cooling will not be correct. Choose liquid cooling The alternative is AIO liquid cooling (which comes from ‘All In One’). If you have read this far, you can already imagine that we are facing a more sophisticated refrigeration method. In fact, it is not only more sophisticated because of the way it extracts heat (which also, as we will see below), but it is a sophisticated system in sight. It’s an eye-catching system: the compact block above the processor and the case-mounted radiator offer a much cleaner look than the bulky air cooler. This system is based on the same thing as the air heatsink, that is, a metal block that comes into contact with the processor (with thermal paste, of course). What’s happening? What happens through that block? a liquid that absorbs heat and carries it through tubes to a radiatorwhich is actually quite large. This has fans nearby that cool the liquid and, in this way, the cycle begins again. Let’s go with its strong points. Remember what we mentioned above about the price, but, in essence, liquid dissipates heat better than air. In addition, the fans of this type of system are usually quieter than the one with the air cooler, which means less noise. Although be careful, because the pump can also make a little noise. There is also the issue of space, since the block that goes on top of the processor is much less bulky than the air heatsink. Bad turn. This cooling system, being more complex, is much more difficult to install. Besides, It also has a shorter useful life. (they usually have a useful life of between three and six years) and, if there is a coolant leak, it can cause serious damage to the PC (it is not common, but it can happen). They are also more expensive systems, as we say. The good and the bad of both options, face to face air heatsink liquid cooling THE GOOD 🟢 It is a cheaper system that works well and is more durable. It can be more efficient when cooling and aesthetically it is very cool. THE BAD 🔴 It takes up a lot of space inside the PC and can make a lot of noise. It is more expensive and, if it causes problems, it can be a headache. Ideal for: Have a long-lasting cooling system without many complications. Users who put a lot of effort into their processor and who want the interior of their PC to be more aesthetic. Neither of these two options is bad for your PC, but they have their advantages and disadvantages. Beyond what you want to spend, what you have to take into account when choosing is What needs do you have and what use are you going to give to your computer?. If what you are looking for is a system that will last for many years and you will hardly have to worry about it (beyond cleaning it and changing the thermal paste), then the ideal is to choose an air heatsink. Because? Because these systems are simpler and it is difficult for them to break. In addition, a good … Read more

cooling AI is the new gold mine

by

The gaming market is a cruel ecosystem, where many brands that once dominated the overclocking forums are today just a vague memory in the memory of more veterans. However, there are exceptions of companies that, far from sinking, knew how to read market signals and pivot in time. This is the case of CoolIT, a brand that manufactured liquid cooling for gaming and that today it is a key piece in the gear that moves artificial intelligence, one that is worth billions. 3,000 million. This is what CoolIT is worth today, or rather it is the value at which KKR is trying to sell it. The controversial investment fund bought the company in 2023 for 270 million dollars and now, just three years later, they aspire to multiply their initial investment tenfold, according to Financial Times. CoolIT is no longer in the business of cooling gaming PCs, its business is now focused on the data centers that power AI. The beginnings. The company was founded by two Canadian gaming enthusiasts in 2001, when the concept of gaming PCs was beginning to take shape. To better understand the moment, it was the time of Windows 98, the most cutting-edge graphics card was the NVIDIA GeForce 3, the processors were Pentium 4 and RAM was measured in megabytes. In this context, CoolIT launched itself into the manufacture of liquid cooling systems and, although it was not one of the top brands (it worked more as OEM for others like Corsair), had several important milestones. One of them was the launch of Domino ALC which was much lighter than other similar systems and hardly required maintenance. In 2009 they patented their SplitFlow cooling plate technologywhich represented an important leap in the sector. From PC to data centers. 2012 marked the turning point for the company. Its focus shifted to data centers, creating direct liquid cooling systems for servers. In 2015 they started a collaboration with Hewlett Packardproviding cooling to its HPE Cray supercomputers and HPE Apollo servers. They also put the cooling of the Dell servers since 2017. CoolIT in the age of AI. At the moment The construction of data centers is at an unstoppable pace and faces various problems. Energy is the most seriousbut refrigeration is not far behind and even has been the subject of controversy due to water consumption. Against this backdrop, CoolIT was in the perfect position to ride the AI ​​wave and currently has a catalog of high-end solutions, such as its distribution solutions (CDU) capable of supplying up to 2,000 kW of liquid cooling capacity for large AI and high-performance computing server farms. The future. At the moment the sale of CoolIT is in an early phase, but KKR would already have several possible buyers. According to the Financial Times, there are around 3,000 data centers under construction in the US alone, which for companies like CoolIT is a very important moment of growth. There have already been other billion-dollar transactions by companies dedicated to refrigeration, such as Boyd Thermal (9.5 billion) either PurgeRite (1 billion). The case of these companies does not remember that AI is not only about OpenAI, Anthropic or Google DeepMind, there is a whole ecosystem of companies making money with this.

Google is going to build a mega data center in a state where the drought is atrocious. Your cooling plan: use air

by

The American state of Texas has been dealing with heat wavesdroughts and a increasing pressure on its aquiferswhich makes it on paper one of the worst places to set up a data center. Well, Wilbarger County in Texas is just the place chosen by Google to set up your next data center. But big tech hides an ace up its sleeve: it is not going to use water for cooling, but air. Context. Briefly, a data center is an industrial facility full of servers where information transmitted over the internet, such as AI responses or your Google photos, is stored and processed. And if your personal computer requires cooling when it has been working with a certain intensity for some time to dissipate heat, more of the same with servers, which operate 24/7. The usual thing in these plants is to use thermal dissipation systems with water, either with chillers, evaporation or direct cooling with immersion, thermally efficient solutions, but problematic if water is scarce. The problem? That Texas is an oven that is not for buns: its drought is pressing. But Texas is not a foreign place for Google: it has been in that state for more than 15 years, where it has operational centers in Midlothian and Red Oak and already plans to build two more campuses in Armstrong and Haskell Counties. It’s very serious. The project. The Wilbarger County data center will reduce water use so much that it will restrict its application to basic campus uses such as kitchens and services. As? Google has not provided details of the technology, only that it will be advanced air cooling. Cooling with air in such a hot scenario implies greater energy consumption, so the problem now becomes electricity. What Google proposes is a “Power first” model. In short: the data center goes hand in hand with its own renewable electricity generation plant. Google’s energy partner for this project is AESone of the largest producers of renewables in the US, with whom it has a 20-year energy purchase agreement at an agreed price. This is how both win: AES has stability to build the plants and Google has the guaranteed supply and price. Furthermore, according to Google, they already have the land and the interconnection signed, which saves bureaucracy and launches the project into the construction phase. Why is it important. Because according to EESI estimatesa medium-sized data center can consume 416 million liters per year for thermal dissipation alone, the equivalent of a thousand homes. And if there is a shortage of water, allocating it to meet the needs of a data center is hardly justifiable. Wilbarger’s project solves this with air cooling, removing the precious commodity of water from the equation, but also from the electrical grid itself: Google cooks it and Google eats it (with the help of AES). Given that the demand for computing continues to grow, a model that does not consume water or overload the network emerges as a solution to a resource management problem. In figures. For Google, Wilbarger County is not a pilot plant and its size demonstrates this: 0 liters of water for cooling. The project will provide 7,800 MW of power to the Texas grid. The agreement between the technology and energy companies is for 20 years. Google advertisement an investment item of 40 billion dollars for Texas in November 2025 and has provided a $30 million fund to boost energy initiatives in Texas from 2026 to 2028. It won’t be easy. Although Google has been cryptic when it comes to reporting what the technology, its capacity and needs will be, the reality is that when cooling with air in a hot climate, the pressure is transferred to the electrical grid. On the other hand, and although this specific project points the direction of a possible solution to this problem, we will have to see if and how it can be scaled, because there are more and more data centers and the climate is increasingly more extreme.

Now we know Russia’s trick to multiply his drones. It is called “cooling units” and comes direct from China

by

If the question is how far Beijing’s help comes to Moscow with the Ukraine War in the background, the answer is very wide. We knew through documents obtained By Bloomberg that the production of Russian drones was being favored by the use of intermediary companies with China as main actor bound. Now we know something else. The engineering of deception to overcome sanctions. Clandestine flow. I told it in Exclusive Reuters. Apparently, Russia has managed to maintain and expand the production of its drones Kamikaze Garpiya-A1despite the sanctions imposed by the West, thanks to a sophisticated undercover import scheme that involves Chinese companies. Customs documents, internal contracts and invoices reviewed by the medium reveal that the L550E engines manufactured by the Chinese company Xiamen Limbach Aviation Engine Co. continue to arrive at the Russian state company IEMZ KUPOLnow through a Signature called Beijing Xichao International Technology and Trade. To avoid detection, engines are tagged as “Industrial cooling units” in transport documents, which has allowed Your shipment From Beijing to Moscow (and from there to Izhevsk, headquarters of the Kupol plant) without alerting Chinese customs authorities or formally infringing the country’s export legislation. Mass expansion. An internal Kupol document confirms that the company has signed a contract with the Russian Ministry of Defense to manufacture More than 6,000 Garpiya In 2025, tripling the production of the previous year. For April, more than 1,500 units had already been delivered. These drones, long -range and great precision, are regularly employed to Attack civil infrastructure and military deep in the Ukrainian territory. According to kyiv’s intelligence, Russia is using some 500 Garpiya per month. Based technologically on the Iranian Shahed, the Russian model has become a fundamental tool of Kremlin’s war effort, now enhanced by Chinese components that include not only the engine, but also Navigation and control systems. Ghost Companies Network. The path of engines to Russia is carefully disguised. After initial shipping from China, He had Reuters that engines are received by a Russian cover company called SMP-138owned by Abram Goldman, which in turn forwards them to another Russian company, Libss, final responsible for supplying Kupol. A contract between Libss and Kupol Reviewed by means Specifies specifically that the products should be identified as these “cooling equipment” to avoid suspicions. Chinese commercial companies Sichuan Airlines and China Southern Airlines have been used to transport these pieces Criticism of Russia since October 2023, despite the penalties in force. None of these airlines or the companies involved answered the Reuters questions. Ambiguous position. The Chinese Foreign Ministry, in response to the environment, He denied knowledge of these shipments and reiterated that the country strictly apply export controls of double -use goods, in addition to oppose sanctions Unilateral not endorsed by the UN. However, the reality of the continuous flow of military technology towards Russia calls into question that narrative. The Xiamen Limbach company was sanctioned in October of 2023, after an earlier Reuters report that already identified its role in the manufacture of the Garpiya, which caused new intermediaries such as Xichao They assumed the relief. In spite of these measures, or Xiamen or Xichao have given explanations, and the trail of responsibility is more than diffuse among layers of screen companies, documentary opacity and legally ambiguous trade routes. Diplomatic warnings. Plus: Revelation arrives at a time of Growing diplomatic tension Between the European Union and China. The president of the European Commission, Ursula von der Leyen, will meet with Xi Jinping and Li Qiang at a summit marked by Chinese support suspicions to Russian military machinery. European diplomacy, headed by Kaja Kallas, He has warned Beijing that allowing this type of trade puts the security of the continent at risk. China, meanwhile, insists that He has not exported Lethal weapons and that, if Russia uses its civil products for war, the same could be said of Ukraine. However, according to three senior European security officials, the case of Garpiya demonstrates that the Chinese supply It is not accidental or marginalbut part of a functional network that actively supports Kremlin’s military effort. European deterrence and strategic game. Experts Like Meia Nouwensof the International Institute for Strategic Studies, point out that China’s priority interest is to keep the United States focused on Ukraine, thus avoiding a direct confrontation in the Indo-Pacific. The implicit strategy would be to prolong the European conflict to gain margin of maneuver in Asia. For Brussels, however, the immediate priority is Cut the flow of critical components. Although the EU does not require China to break economic relations with Russia, it does insist that it reinforces its customs and financial controls to avoid the transit of sensitive products. For now, the proliferation of undercover engines and fictional companies shows that, on the Ukrainian battlefield, the China’s technological shadow is increasingly difficult to ignore.

The cooling bases for laptops were for an omnipresent time. Today they have disappeared without realizing

The Digital photo framesYoplait yogurts, the Aquarius Cola. There are objects that disappear without warning, and in that list they may be entering the Refrigeration bases for laptopsthose armathes with fans that populated the desks a few years ago. And that now they seem to have vanished from stores without anyone saying goodbye to anyone. In the magic 2000, when Pentium 4 They turned any laptop into a reactor turbine, seemed almost mandatory, especially with the arrival of summer. Today they seem as anachronistic as the coves for disks. What happened? There are several theories that seem feasible together. One of them is the fifteen years of silent engineering. Manufacturers have refined the thermal design, optimized architectures and perfected the manufacturing process until heat a residual problem. Apple Silicon It marked a turning point, but even Intel and AMD chips have won in efficiency … although they continue to heat up with demanding tasks. But in everyday use they do not seem to need that external cooling. On the other hand, it is Our way of using computers. The majority of heavy software that required local resources has migrated to the cloud, especially consumer focused. We live in browsers, We consume Saaswe delegate in remote services. The laptops are no longer so much work stations to process as internet windows that do not require too much effort. Not the one before. Meanwhile, The mobile has absorbed a lot of screen timerelegating the laptop to specific tasks, but not to do so much and for so many hours as it is. The cooling bases are thus bind to the same accessory cemetery where the remains of Ninety liquid crystal screen protectorsthe organizing boxes of CDS, the silicone keyboard protectors, the box with lock and everything to save disks.
