The Xpressar Components
The heart of any phase change cooling system is the compressor. This is where the gas is pressed into a liquid and forced through the other components.
Thermaltake used a 49 watt compressor and here we also see on the label that Thermaltake used R134a refrigerant in their system. This is the same that is used in most passenger cars manufactured since the middle 1990’s. Thermaltake’s compressor uses 12 volts of power so it is powered by the PCs power supply.
From the compressor the R134a is pushed to the condenser. The condenser resembles radiators used in liquid cooling systems and serves the same purpose.
The magic happens on the evaporator just above the processor core. Here the liquid expands into a gas. During this change of phase, the liquid rapidly loses pressure causing the gas to become super cooled while inside of the evaporator.
The gas is then pushed back to the compressor where the cycle continues again.
