WebOct 21, 2014 · Just a thought, if your Cryocooler is a simple build, you might get away with plain bearings in some parts, as friction is not so important. The most important part (almost forgot) is the cooling system, you will need a water jacket, and a good size radiator to extract the heat. You'll need a lathe, and maybe a milling machine, welding and ... WebThe Stirling cycle cooler is a member of a family of closed-cycle regenerative thermal machines, ... including the reversed Stirling cycle, net work input is necessary in-line with the second law of thermodynamics.
