would it be possible to have a closed loop of ln2 with some hard core compressor? (obviously i cant do this since i have no money nor knowledge, but im intrested to know if it would actually work)

There was a discussion of this here

The general consences was no since ln2 must have a phase change directly to have any convection. Meaning without oxygen there is no transfer.

yeah, they also have another thread here http://www.overclock.net/cooling-experiments/13663-automatic-refilling-ln2-cooler.html

 which states you could, make a semi- closed 

and another discussion of the idea further here http://www.overclock.net/cooling-experiments/47538-closed-loop-liquid-nitrogen-cooling-3.html

 however alot of these forums go against each other one thread tells us you can, another tells us you cant. and i dont know enough to sperate the stupid people from the people who actually know what they are doing and what they are talking about. obviously at least a semi-closed loop is possible, but i think a full close one should be possible with a good compressor.

better yet, how about a solid nitrogen cooler O_O think of the overclocks!

Would be better to use a wick based heatpipe and a heavy refrigirante such as r502 or r605. The results would be drastic

could you explain more? i am not familiar at all with phase change cooling (a ln2 closed loop would end up being a phase change loop anyway)

Instead of using a barium ether solution such as what current heatpipe tech is using. Use a more commercial approach and use a refrigirante gas such as what is used in  commerical size airconditioners  use the highly gasesus r500 or r600 series fluid since it would be much more effient at heat displcement where a compressor would not be present. This kind of tech already exist all but a much larger scale. My idea falls more of the concept of a thremo syphon and is a concept that is already in testing with some success. I would say within 2 years a retail ready kit should be available.

I'm with you.  At the rate this conversation's progressing, I calculate we're about 17 posts away from one of them constructing Maxwell's demon and cooling on the quantum level.

What part of "Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn" don't you understand?

I thought that is what they were doing

nah, were just building a doomsday machine, and we need to cool it off WITH SOLID NITROGEN! OHHH YEAH!

Short and simple of what i was sayiing was to use freon instead of themo oil in heatpipes for extreme cooling. Big Smile
