You can't get much simpler than the Ranque-Hilsch vortex tube. Vortex tube - Wikipedia, the free encyclopedia No moving parts, hot air out one end and cold the other. The only drawback is a mountain of compressed air needed. In the case of my Vortec 610 15SCFM @100psi that keeps my loud 5hp, 80 gallon compressor running almost continuously. Peltiers on the other hand would require massive regulated DC power and a heat sink for the hot side, some kind of heat exchanger for the cold side. Both Peltier and Vortex tubes are very inefficient. BTW I do have a pile of single-stage Peltier devices that I hope someday to make into something, just not a compressed air cooler.
