Phase Change - use of very cold (cryogenic) liquids to cool your processor (liquid nitrogen or dry ice (CO2)

The phase change come from the fact that you use the latent heat of vaporisation to remove most of the heat from the CPU say, hence the name phase change. Needs lots of insualtion and careful handling/set-up to use properly

Nope no LN2 or dry ice involved at all in phase change cooling.

It works on the same principles as a freezer with a compressor/condensor/suction line etc. And the use of refridgerants (usually R134a, R402a, R404, R507 are most comonly used for single stage solutions which your most likely to be looking at.

One of the main components is the compressor from there the refridgerant is "pumped" and compressed. The flow of the refrigerant moves from here to the condenser, where the Vapour refrigerant condenses into liquid refrigerant The liquid refrigerant then moves into the drier/filter where impurities and moisture are filtered out. From the drier/filter, the liquid refrigerant moves into the metering device, which in most cases will be a capillary tube when using on a PC. Through this thin length of copper, the liquid refrigerant will be metered into the evaporator. Here is where the CPU gets cooled and most of the liquid vapourizes here. The Vapour refrierant moves from the evaporator into the suction line and moves back to the compressor. And the process continues.
