95% Data-Center Cooling Energy Reduction Thanks to Fluid-Submerged Servers : TreeHugger via @TreeHugger

95% Data-Center Cooling Energy Reduction Thanks to Fluid-Submerged Servers : TreeHugger via @TreeHugger

Our system will cool up to 100kW in a 42U rack in its current configuration. This is equivalent to an air-cooled system near 120kW since nearly 20kW of that 120kW would be used by server fans. Our system offers orders of magnitude better convective cooling than an air-cooled system and thus can handle higher densities. Also, full immersion of all components is unique to dielectric fluid submersion. Without full submersion, air is still the primary heat transfer medium and with it comes all of the limitations of air. For the rare CPU that is "thermally coupled" with a liquid, which entails a water-filled heat sink or equivalent, other components still require air cooling.
