A new to cool down data center servers.
Over the years, Microsoft has been exploring various ways on how it can cool down its data center servers, this included putting them on the seafloor in replacement of the traditional cooling system. This time, Microsoft is testing a two-phase cooling solution contains boiling liquid.
The liquid in question is a non-conductive cooling fluid that has a low boiling point of around 122F (50C) which is lower than the boiling point of water. Boiling this liquid creates a sort of vapor cloud that comes in contact with a cooled condenser located above the tank. Once the liquid reaches the top it then goes back down, ready to repat the process. Through this, the heat is transferred from the server tank outside to a dry cooler where it is dissipated. This sort of low-temperature boil allows the servers to operate continuously at full power without overheating.
“We are the first cloud provider that is running two-phase immersion cooling in a production environment,” said Husam Alissa, a principal hardware engineer on Microsoft’s team for datacenter advanced development in Redmond, Washington.
Microsoft also highlighted how immersion cooling, as to how it was referred to, can also reduce server power consumption by up to 15 percent. The efficient cooling also means that Microsoft can overclock the servers without the risk of overheating. Details about immersion cooling are explained on Microsoft’s blog.
The company also highlighted the benefits of immersion cooling, where the two-phase solution can allow machine learning software to manage resources more efficiently across the data center. Since this cooling technology doesn’t use water, it aids in Microsoft’s commitment to replenish more water than it consumes.
While the technology is great – we’re thinking about how this idea can be implemented to be used by consumers. If it proves to be efficient, then we might see liquid-cooled devices and appliances placed around our homes in the near future.
