✦ Synopsis

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 we present in this paper our 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.
