here i will outline (and update, as my project progresses) my computer cooling project, involving both vapor phase refrigeration and thermoelectric cooling.
i've been thinking for some time, wondering how i could set up a really badass cooling system. ok here goes.
how about if a pelt were to be used with a vapor phase refrigeration unit? no, not with the pelt directly on the evaporation plate, but how about if the evaporation coils were in a resivoir of liquid that can go to extreemly low temps? in this way, the vapor phase refrigeration unit's evaporation coils would have MUCH more surface area contact with what its cooling, and hence absorb more heat from it ^_^. this super-cooled fluid could then be pumped through an insulated tubing system to a waterblock. that's what has the pelt attached, the water block. and, with applying such a freezing cold liquid to the hot side of a pelt, the cold side would get EVEN colder .
with a vapor phase refrigeration unit from lets say.. a refrigerator, (like i just happen to have , hehe) im sure temps WELL below 0C would be feasable.
the beauty of this system is that you can keep the same vapor phase refrigeration system and peltiers, instead of having to upgrade every time you switch to a new socket (not that often but hey.. how often do you really wanna shell out $600+ for a prometia?). so the only thing that would need to be upgraded is the waterblock and cold plate. other than that, you can keep the whole rest of the cooling system, and who says it only hasta be attached to one thing? you could have it hooked up to a gfx card as well, and supercool that too. (can't do THAT with just 1 prometia )
here is what i've done so far.
1) i have a 1/3 HP compressor removed from a refrigerator
2) i'm 99% sure on using isopropyl alcohol for what i'll pump through the WCing circuit
3) i'm going to get special tubing and possibly coat my pump with some type of laquer to prevent the alcohol from eating it up
4) i want to convert the compressor to use propane (since i believe it uses freon, and freon is no longer readily avaliable) and possibly use a mixture of R134a and argon later on down the road
5) i'm going to use a hard start kit to power the compressor
here are some things i'm either having trouble with / haven't decided on / having trouble deciding on:
1) how long to make the evaporation coils
2) how long to make the condensation coils
3) what diamater capillary tube to get
4) what diamater evaporation coils to get
5) what diamater condensation coils to get (but i'll probably end up buying a large sheet of condenser and cutting it to fit)
6) how to clean the compressor
well that's mainly what i'm thinking about right now.
any comments/suggestions are greatly appritiated!
