Title: Cooling apparatus using metal hydride
Inventor: KO NAOKI
IPC: F25B17/12
Filed: 1989-03-31
Abstract: PURPOSE:To reduce the size of a refrigerator using metal hydride and enable easier control thereof, by a method wherein containers, where the first and second metal hydrides are contained respectively, are connected to each other through a hydrogen ON-OFF valve, and heating of a heater, the heating medium and refrigerant ON-OFF valves are controlled unitarily. CONSTITUTION:A container 1 where a first metal hydride M1H is contained is connected to a space 3, to be cooled, by a gravity type heat pipe 7 to carry out heat- exchange. A container 2 where a second metal hydride M2H having a hydrogen pressure-temperature equilibrium characteristic different from that of the first metal hydride is contained. Heat absorption is caused by the release of hydrogen on the M2H side when hydrogen transfers from the M1H side to the M2H side. A heat absorber 6 and a cold storage material 9 contained in the space 3 cool the inside of the space 3 by using said heat absorption as freezing heat. After hydrogen is occluded on the M2H side, the container 2 containing M2H is heated by a burner 21 to return hydrogen from the M2H side to the M1H side, however, a small capacity burner or other simple combustion devices are satisfactory enough for that purpose. Thus, as the heat transfer in the repeating operation cycle is carried out by the gravity type heat pipes, the heat can be transferred very quickly.
