Use heat to cool?

[Shadow_Storm56]

Bizarre thought, propane fridges use a small flame to evaporate a fluid and cause a phase change. Could it be possible to make a PC that is cooled by it's own heat this way or am I just having a dumb thought.

oh yeah, phase change coolers are becoming bigger in the exotic cooling scene.

Technically yes, but I don't see it being practical or cost efficient.

I don't mean a standard phase change cooler I mean one that uses to PC's heat to change the phase and cool the PC. Frig the heat from one of could be used to cool another.

The expansion valve is what causes the phase change in PC phase change coolers.

There's no need to add any flame, or use any heat, a simple nozzle is enough.

Then that's literally what this is:

The heat from the CPU evaporates the liquid.

This is exactly what a heat pipe does. So this is already in millions of PCs.

Really? Huh I honestly thought it was just a copper tube that conducts heat because copper

Nope. It has a fluid and a wick inside. On the hot end it evaporates carries heat away.  On the cold end the vapor condenses and travels back along to wick to the hot end.
