THERMAL SORPTION PUMP Russian patent published in 1994 - IPC

FIELD: refrigerating engineering. SUBSTANCE: chemical thermal pipe 1 is made in form of hollow hermetic container whose interior is divided into at least two zones 2 and 3 for receiving hydrides 4 and 5 connected by means of partitions 6. High-temperature and low-temperature hydrides 4 and 5 are located in these zones. Heat-removing and heat-supplying devices are made in form of at least two thermosiphons 10, 11, 12 and 13; object to be chilled is made in form of one low-temperature source 8 of heat. One thermosiphon 12 of heat-supply device is connected with high-temperature source 9 and remaining thermosiphons are connected with low-temperature heat source 8. Number of thermosiphons is equal to number of low-temperature hydrides. Number of pairs of thermosiphons of heat-supply and heat-removing devices is equal to number of zones. Container is located between evaporation zones of heat-removing devices and condensation zones of heat-supply devices which are arranged at distance from each other equal to thickness of the container whose larger side is located along evaporation zone of heat-removing device. EFFECT: enhanced efficiency. 4 cl, 7 dwg
