Immersion cooling is an IT cooling practice by which IT components and other electronics, including complete servers, are submerged in a thermally conductive dielectric liquid or coolant. Heat is removed from the system by circulating liquid into direct contact with hot components, then through cool heat exchangers. Fluids suitable for immersion cooling have very good insulating properties to ensure that they can safely come into contact with energized electronic components.
In SINGLE-PHASE servers are installed in an immersion cooling with dielectric fluid. The liquid remains passive during the cooling process. This system requires circulation of the dielectric liquids by pumps or by natural convection flow
In TWO-PHASE applications the fluid make changes phase. The boiling point of the fluid is chosen and the bubbling causes a stage change from fluid to gas, which gives two-stage drenching cooling. The vapor generated should be condensed back to the liquid form heat exchanger. Once condensed the two-phase coolant drips back into the primary cooling tank.
Although both single phase and two phase immersion cooling use liquid circulation to cool your system, single phase uses a pump to force the liquid through a tank while 2-phase uses a heat exchanger to condense the liquid and turn it back into a liquid.
