ABSTRACT:
A .sup.3 He evaporation refrigerator, comprising an evaporator having apparatus to localize liquid and vapor phases in selected regions while allowing evaporation of liquid to occur in normal operation; two adsorption pumps connected via vent ducts with the evaporator to receive .sup.3 He vapor, alternately, there being valve means associated with each pump; heater means associated with the pumps to cause .sup.3 He desorption by the pumps; a condenser-collector to receive desorbed .sup.3 He, and electric force means to hold .sup.3 He liquid at a flow path outlet from the condenser-collector; and a flow path from the condenser-collector back to the evaporator.
