Incooling is building servers that use liquid to cool down • TechCrunch


method Inkparing CEO Helena Samodorova sees the IT world facing two major crises: an energy crisis and a supply chain crisis. For IT teams, meeting new, climate-friendly energy budgets is a challenge, especially when dealing with legacy computers. At the same time, obtaining improved and less energy-absorbing machines is becoming more difficult due to charge buildup and because devices run quickly against efficiency limits.

Motivated to solve dual crises—an ambitious goal, to be sure—Samodurova co-founded Incooling, which focuses on efficiency in data centers. Incooling, which is promoted in Startup Battlefield in disabledesigned a dedicated server with a proprietary cooling system that it claims allows superior thermal management, allowing the server to achieve high efficiency standards.

“Our design and cooling allow us to unleash the full potential of today’s technologies that are unfulfilled due to heat and space constraints,” Samodurova told TechCrunch in a recent interview. “By using our technology, we are able to increase performance in scalable and non-scalable tasks by accelerating existing hardware and saving … in energy use.”

Samodurova began developing Incooling technology in 2018 with Rudie Verweij, the company’s second co-founder. The two met at High Tech Campus, a technology hub and R&D ecosystem on the southern edge of the Dutch city of Eindhoven, during a hackathon.

After partnering with CERN in Switzerland — Samodurova has benefited from connections there through her work at HighTechXL, an incubator that previously commercialized CERN technologies — Samodurova and Verweij designed prototype server hardware. Their server uses a two-stage cooling system with coolers designed specifically for extreme heat and conditions, which Samodurova claims allows it to reach some of the fastest processor speeds of any server on the market.

Incooling’s secret sauce, if you will, is the cooling and control design mentioned above. Samodurova says the system is able to respond quickly to fluctuating thermal loads, adapting to ensure the server processor remains within safe temperature ranges. “As we enter a new market – refrigeration and account – we don’t really have direct competition,” Samodurova said. “Cooling companies focus solely on cooling companies and servers on the end server only, while we take the best of both worlds and combine it into the ultimate custom solution where every major component is specifically engineered to perform at its maximum designed capacity and in this way we improve the bottom line above current market standards.”

Incooling is certainly important. it’s a estimated that data centers consume about 3% of global electricity supply and account for about 2% of total greenhouse gas emissions worldwide; refrigeration costs can the total About $2 billion a year. While traditional data centers Consume Less energy than they used to, the the demand for Statistics – Count To drive AI-powered applications and accommodate the growing public cloud threatens to derail progress.

Samodurova was loath to reveal too much about how Incooling is managing to improve the efficiency of its servers — it’s early days for the company, which is in the midst of a capital raise. But she said the refrigeration system uses phase change refrigeration, a technology that could provide a more reliable way to cool electronics than conventional air conditioners and air compressors.

Phase variable refrigeration harnesses the latent heat of evaporation of the refrigerant – the point at which it transitions from the liquid phase to the gas phase and vice versa. The liquid in a variable phase cooling system collects heat until it evaporates, at which point it becomes less dense and travels to the cooler part of the system. There, it dissipates heat, and during that, the gas turns back into a liquid and is recycled toward the heat source.

Phase change cooling offers many benefits, perhaps the most important of which is reduced energy use and thus costs. Unlike a fan, for example, the system does not require a constant supply of electricity to cool the components. As an added advantage, since it has no moving parts, it is less susceptible to mechanical damage.

It’s hardly a new technology. Features of phase change cooling in Xiaomi Mi 11 Ultra circa 2021 smart phone. And on the server front, Microsoft has I tried With a two-stage cooling system on the banks of the Columbia River, using steel tanks to submerge servers under water and carry heat away from their processors.

Competing startups experimentation With phase change cooling for servers too. Submersible cooling – that supports the adventure – diving Servers are in a special fluid and content, allowing technologies to switch hardware components even while the system is running. Meanwhile, ZutaCore’s processor cooling technology dissipates heat through liquid contact.

But Samodurova stresses that Incooling, which currently has a team of 12, is “constantly growing” as it prepares to mass produce its server next year. It won’t answer questions about potential customers or expected revenue, but it did claim that one of Incooling’s prototypes has been operating in a data center for over a year.

It is also worth noting that Incooling has a file partnership With PC manufacturer Gigabyte to use the latest R161 Series, G-Series and H-Series server platforms as a test of Incooling technology. In a preliminary round, Incooling He said It achieved lower core processor temperatures of up to 20°C – resulting in up to a 10% increase in clock speed and a 200W lower power draw.

“The pandemic has shown how much we rely on technology and how important reliable communications are,” Samodorova said. “Due to the pandemic, we have been able to directly demonstrate the added value of Incooling by bridging the gap between the demand for computing and existing solutions.”
