Multiphase cooling

Updated: 12/31/2022 by Computer Hope

Multiphase cooling is a technology used to remove heat from a computer hardware component; thus allowing the system to run at a lower temperature both in general and under maximum stress. The process of multiphase cooling is 2000 times more efficient than air-cooled applications and 500 times more efficient than liquid cooling.

How it works

Multiphase cooling starts with a specially formulated, non-conductive coolant with a very low boiling point. As the coolant's temperature increases, it turns into a gas, rises, and then condenses back into a liquid once it reaches the heat sink (condenser). Any time a substance undergoes a phase change, it requires a large amount of energy, called latent heat. This energy is taken, as heat, from the component being cooled.

Benefits to multiphase cooling

The numerous advantages of multiphase cooling are a direct result of the properties of thermodynamics. Using latent heat, the system requires no moving parts (e.g., pumps, electronics), is self-sustaining, smaller, lighter, and quieter than any liquid cooling system.
