Summary

The reliability requirement associated with the development of cryocoolers for space applications requires that the cooler shall be simple, have no friction, or better, have no moving parts. CEA-SBT has acquired a considerable experience on both aspects and the authors present the past and current cryogenic sorption coolers activities. Adsorption coolers rely on the capability of porous materials to adsorb or release a gas when cyclically cooled or heated. Using this physical process one can design a compressor/pump which, by managing the gas pressure in a closed system, can condense liquid at some appropriate location and then perform an evaporative pumping on the liquid bath to reduce its temperature.
