PROBLEM TO BE SOLVED: To provide a chemical heat storage device capable of efficiently transmitting heat generated by a reaction material in a reactor to a heating object.SOLUTION: A chemical heat storage device includes a heat exchanger 3 with a reactor having a reaction part 15 and a plurality of heat exchange members 16, and an adsorber connected so that NHcan flow between the reaction part 15 and it. The reaction part 15 is stored in the reactor 17, and has a reaction material 18 generating heat through a chemical reaction with NHand desorbing NHby stored heat of exhaust heat. The heat exchange member 16 has a heat exchange part 21 forming an exhaust gas flow passage 21a through which exhaust gas flows from one end side to the other end side and performing heat exchange between the exhaust gas and the reaction material 18, and a cylindrical heat exchange part outer cylinder 20 provided on an outer periphery of the heat exchange part 21. The heat exchange members 16 are buried in the reaction material 18 along a direction perpendicular to a flow direction of the exhaust gas in the inside of the reactor 17.SELECTED DRAWING: Figure 3 |
