Vapor Phase Change Cooling
This is something I just learned about from a friend (who is using it for some reason...), and after a little research, is absolutely ingenious.
For those of you that do not know what it is, the basic explanation is this:
A fluid that is a gas at ambient temperature is compressed to around 200 PSI at 70 degrees Celsius. The fluid is then fed into a condenser (a radiator for gases). This drops the temperature back to ambient, and condenses some of the gas to liquid (but not much). The gas is then fed into extremely thin tubes of a set length, around .7 millimeters thick. This helps condense the gas into liquid, with a few bubbles, at a very cold temperature. The liquid flows through the tube, into the evaporator over the processor (or whatever you are cooling). The evaporator has a larger chamber, so the liquid expands back into a gas. This is an Endothermic reaction, sucking the head from the processor and into the gas. Then, it travels back to the compressor, still very cold. This cold gas is helps to cool the compressor, which then repeats the cycle.
This can keep temperatures of the processor in the 10 degree Celsius range, which is just ridiculous.
It also looks a little tough to build the setup, but would be worth it for a high powered computer with a highly overclocked processor.
Any thoughts on this?
