In a normal Stirling engine, you put heat in at the hot end of the machine (the heat source) and get mechanical work and less heat out of the other, cooler end (the heat sink). … That turns a Stirling engine into a cryocoolera very efficient cooling device. How does the cryocooler work?

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 ... WebA Stirling engine operates on a closed thermodynamic regenerative cycle with the same working fluid repeatedly compressed and expanded at different temperature levels so there is a net conversion of heat to work or vice versa. It can be used as a cooling engine, prime mover, heat pump, or pressure generator.
