Is it possible to use liquid nitrogen as refrigerant?

Processor would not get slower, Hz is a frequency however electrical, not vibrational and thus not kinetic.

I know this, what I was pointing out was that the properties (such as conductivity, reactivity, etc) of the matter the CPU is made of would change and therefore change the way it works, or not work in the most probable case.

Silicon has been shown not really to change much at really low temps, but it can get so cold that material shrink snaps internal traces in the CPU, but that was before intel switched process around 110nm.

How much do you gain overclocking with LN2 vs dry ice or a phase change chiller?

Well can be a good bit more, but its very chip dependent.

You can use propane, it has a atmospheric boiling point of -41C.

That, my friend, sounds like a serious disaster in the making.....

It seems opinions vary as to whether liquid Nitrogen could, in fact, by some means, be used as a refrigerant. Let's say it was used; what possible benefits might using it provide? (Over freon, say.) Would the process require a much lower volume of liquid or gaseous nitrogen in order to cool a similar area, since it's so freaking cold? Is l.N less destructive to the ozone layer. Could such a system be designed to operate with the use of less energy?

LN2 can't be used as a refrigerant feasibly. It would take multiple thousands psi pressurization to keep it liquid at room temp.
The refrigerants we use (Freon, etc) can be kept as a liquid at room temp with a small pressurization (read: many orders of magnitude lower than LN2).

Also, nice necro.

You could probably use that for an industrial ad system if you have a small compartment to store the cycle components but a really large space

Well nitrogen isn't hazardous to the environment like any of today's more common refrigerants

You realize how much the cost of refrigerators would increase if you were to raise the working pressure by two orders of magnitude, correct?

Is it possible to use liquid nitrogen as refrigerant?
