Multiphase cooling

Updated: 12/29/2017 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, referred to as 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.
