ABSTRACT:
A dual refrigeration system for cooling a sink device is described, which automatically thermally couples the cold refrigerator to the sink device while thermally isolating the warm refrigerator from the sink device. The system includes two gas gap heat switches that each thermally couples one of the refrigerators to the sink device, and a pair of sorption pumps that are coupled through tubes to the heat switches. When the first refrigerator (18) is operated and therfore cold, the first pump (50) which is thermally coupled thereto is also cooled and adsorbs gas to withdraw it from the second heat switch (44), to thereby thermally isolate the sink device (12) from the warm second refrigerator (26). With the second refrigerator being warm, the second pump (52) is also warm and desorbs gas, so the gas lies in the first switch (38), to close that switch and therefore thermally couple the cold first refrigerator (18) to the sink device. Thus, the heat switches are automatically switched according to the temperature of the corresponding refrigerator.
