Abstract: PURPOSE:To simplify and miniaturize a device and obtain the practical one by mounting a cross-fin type heat exchanger with fins, which thin the layer thickness of a thermochemical reaction substance contacting with a thermal medium in a heat-exchange shape, can store the substance and are made up in flat pan shapes, in the device which extracts heat energy, which is changed into chemical energy and stored, as necessary. CONSTITUTION:A cross-fin type heat exchanger 5 with fins 6, to the fringes thereof rising edges 9 with proper height are formed and which are made up in flat pan shapes, is mounted into a shell 4 of a reaction tank 1. When a thermochemical reaction substance such as powdered NaI is entered into the pans 6 and liquefied NH3 into a storage tank (not shown) and the storage tank is heated by means of a coil (not shown), NH3 is changed into a gas, is sent into the reaction tank 1 and reacts thermochemically, and the heat of formation is generated, and transmitted to a thermal medium in heat transfer pipes 7. Since the product is stored in the pans of each fin 6, the efficiency of heat exchange with the heat transfer pipes 7 is improved. In this case, when the rising edges 9 are lowered fin pitches are made smaller, the heat transfer pipes 7 need not be increased and the reaction tank is compacted.

Abstract: PURPOSE:To bring about turbulence of heat transfer liquid mediums so as to improve the heat transfer coefficient, by fixing a mesh member on the heat transfer surface of each of heat exchange plates that are laminated. CONSTITUTION:The heat exchange plates 1 are layered and assembled with a packing 5 therebetween so that passages are formed by the heat exchange plates 1 with the passages 4a and the passages 4b alternatively arranged. The high temperature heat transfer medium 6 is allowed to flow via the passages 4a and the low temperature heat transfer medium 7 is allowed to flow via the passages 4b so that the heat exchange is carried out. One surface of the heat exchange surfaces of each heat exchange plate 1 has the metal mesh 2 secured thereto. Said heat medium 6 and heat medium 7 flows through the spaces defined by the heat exchange plates 2 each having the secured metal mesh 2.

Abstract: PURPOSE:To obtain a heat accumulator which can store excessive heat such as waste liquid or the like from a factory and resupply it by stacking heat storage elements formed of heat transfer tubes and plates or tray-shaped fins in rack shape and bringing the fins into contact with heat accumulating medium for physically or chemically absorbing the heat. CONSTITUTION:Heat storage elements 3 formed by integrally contacting the tray- shaped fins 6 with the heat transfer tubes 5 are stacked in rack shape in a heat accumulator body 2, and heat accumulating medium 9 such as amine complex or the like of metallic halogen compound is placed on the fins 6. When heat medium such as waste liquid or the like from the factory is supplied from a heat medium supply tube 7, the heat accumulating medium 9 is decomposed into metallic halogen compound and ammonia gas to absorb the heat and to then store the heat. The ammonia gas thus produced is discharged out of a system from an exhaust tube 11. When the ammonia is supplied from the ammonia supply tube 10, amine complex is generated to generate heat to heat the heat medium 8. Thus, the heat such as waste liquid from the factory can be stored, and produced again.
