can we not seal it in a plastic bag and let the condensation gather around that?


and im not saying put the computer in a fridge i mean put the computer in a freezer... the condensation turns to ice any way..

There's no point in this for air cooling the components because they need airflow--meaning you'd need air in and out of the case, so pressurizing it wouldn't really work so well.

Besides, operating air-cooled things in lower pressures is bad because there are less molecules to conduct heat away from the components (as you go closer and closer to a vacuum). I don't know that the opposite trend would be better--because when it's under such high pressure, you'd have a much more dense container of molecules, there might be so much kinetic energy from them that cooling would be impossible (hence why something gets hotter when you pressurize it).

I do believe that heat capacity of a gas increases with size and pressure--so the gas can absorb more heat without changing temperature itself, but you still would have to get around to removing that heat from your case.

You guys do understand that telling him he can't do it just encourages him...

Now that i thought about it ... couldnt you just use a modified refrigerator too cool a liquid that would be pumped to a computer seperatly ....

This would make loads of sense if you just run a tube through the wall of the fridge... have a little resivour in the fridge that chills the water and then the water runs back out and to the computer

No need for those huge radiators ....just have a huge fridge that will both keep your computer cool and your beers. (and sodas and icecream and everything else..)


So I I build this do i get a sticky thread?

If you can build this, AND get it to survive running for a few weeks, you would not only get a sticky, you would get a Nobel prize for defeating the laws of thermodynamics.

Speaking of stickys, isn't there one saying this can't be done? If not, there should be.

Back to the OP, the standard sheet metal case, if properly sealed, would blow up like a balloon at probably about 5 psi.

ok guys i maybe a real thermal dynamics newb and probably know nothing about high pressure setups or anything, but i thought the higher the pressure the hotter the air that's why they have inter cooler on 10-15 psi car turbo setups, and also i thought the goal in air cooling is a low pressure case, by making ur exhaust fans move more air out than your intakes so more ccold air is coming in and hot air is not being compressed in the case. if am wrong some one correct me cuz for the last week or so i have been working on making my m9 low pressure and so far it is dow 3 c and also runs colder closed than open.

I dont understand why this wouldnt work - if you just rigged a freezer to be really cold - set a resivour in it that would be attached to two tubes... one going in and one going out of the side of the freezer.

Is the problem b/c you dont loose the heat through some method??? I kinda figure the heat would disipate to the inside of the fridge...perhaps you could use anti-freeze (not sure what that would do to the pump)... I just dont understand why this wouldnt work lol

Naturally he would cool off the presurized air... but ..


NOT SOMETHING FEASABLE. THE END.

Atleast, not someone from OCN; NASA could if they want to dedicate loads of $$ to build it.

EDIT:

FRIDGES WILL NOT WORK BECAUSE THE ENGINE INSIDE OF IT ISN'T MADE FOR 24/7 USAGE >.> it will overheat from having to create all that cold air.

Doing something like this wouldn't violate the laws of thermodynamics. The reason why one does not use a refrigerator/freezer to cool a computer (ignoring things like condensation, etc) is because the crappy compressor used in a fridge are not resilient enough to be run with such a high heat-load coming from the computer, and the compressor would fail soon due to being overworked (it would overheat probably). If you put your computer in something like a large meat locker/industrial freezer, you'd be more than able to "refrigerate" whatever coolant you're using 'cause the heat coming from the coolant/components is so small compared to the load that the compressors normally feel, it's insignificant. But doing so has nothing to do with the laws of thermodynamics, but rather building a compressor that won't crap out from running so often (which is possible, just not cost-effective in most cases).
