What is Immersion Cooling?
Immersion cooling refers to the process of immersing servers, GPUs, ASICs, and other IT hardware in a non-conductive fluid. The fluid is a far more effective cooling medium than air and so higher efficiencies are achievable. Two-phase immersion cooling is similar but the fluid boils on the hot components.
Two-phase Immersion cooling
Servers or other IT components are submerged in a thermally conductive dielectric liquid or coolant. Heat is removed from the system by circulating the liquid into direct contact with hot components, whereby the liquid undergoes a low-temperature evaporation process to cool the hot components and transfer the heat out of the liquid. The gas is cooled again by a heat exchanging method (such as a condenser coil) to allow return flow into the larger liquid volume
Single-phase Immersion cooling
Servers or other IT components are submerged in a thermally conductive dielectric liquid or coolant. The coolant never changes state, it never boils or freezes and always remains in a liquid form. The coolant gets pumped to a heat exchanger where heat is transferred to a cooler water circuit. This technique uses “open baths”, as there’s little (or no) risk of the coolant evaporating. Single Phase is an older technology and 44% less effective as Two-Phase.
