Data Center Immersion Cooling
Keywords: data center, immersion cooling, electronics reliability
Data centers have traditionally been high power consumers. In a “green” data center, instead of being air-cooled, servers are submerged in a non-toxic dielectric fluid that is 1200 times more effective at whisking away heat. By using state of the art liquid immersion cooling, the power required to run each server is reduced by up to 50% and the power required to cool a server room is reduced by up to 90%. Immersion technology largely eliminates the temperature swings that can lead to processor and electronics failures. Micro-arcing is also eliminated as a concern since there is no dust or oxygen in the oil environment. The improved heat dissipation of immersion technology allows operating cutting-edge, higher powered servers comfortably. So, an immersion cooled data center draws much less power and consequently has a smaller carbon footprint than conventional data centers. Preparing a server for immersion is fairly straightforward. Simply remove the fans, replace any thermal paste with foil, and encapsulate the boot disk or use a solid state drive (SSD). Working on a server is equally straightforward. Pull the server out of the fluid and wait for it to drain. Keep a nearby paper towel for any drips.
