Abstract
Cryocoolers for use in cryosurgery and other applications comprising finned tube helical coil heat exchangers and warming gas flow through a warming gas supply line fitted Joule-Thomson nozzle. The cryocoolers use helium, hydrogen or neon as a warming gas which is expanded from the Joule-Thomson nozzle to heat the probes.
