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 that has 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. By using latent heat, the system requires no moving parts (e.g., pumps, electronics), is self-sustaining, much smaller, lighter and quieter than any liquid cooling system.
