CHEMICAL HEAT STORAGE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a chemical heat storage device capable of making a member thin which surrounds a laminate in which a plurality of reaction parts are laminated via heat exchange parts.SOLUTION: A chemical heat storage device includes: a heat exchanger 4 with a reactor; and an adsorber connected to the heat exchanger 4 with a reactor and for adsorbing NH. The heat exchanger 4 with a reactor includes: a laminate 17 in which reaction parts 15A-15J and heat exchange parts 16A-16I for forming exhaust gas flow passages are laminated alternately; and cylindrical piping provided so as to surround the laminate 17. The laminate 17 is configured so that the reaction parts 15A-15J and the heat exchange parts 16A-16I are laminated alternately along the cylindrical piping. The reaction parts 15A-15J include: a flat tube 24; and a reaction material 25 accommodated inside the tube 24 and for generating heat by a chemical reaction with NH, and for desorbing NHby heat storage of the exhaust heat.SELECTED DRAWING: Figure 3
