CHEMICAL HEAT STORAGE DEVICE

摘要

A chemical thermal storage device includes a reactor and an adsorber connected to the reactor via a pipe. The reactor has a stack structure body having a plurality of plate-shaped heat generation parts and a plurality of heat exchange parts alternately stacked. The heat generation part has a thermal storage material that generates heat upon chemical reaction with NH3 and desorbs NH3 upon reception of waste heat, and a metal casing that contains the thermal storage material. The heat exchange part is a passage of exhaust gas and is constituted of a metal fin. The metal casings of the heat generation parts and the heat exchange parts are joined to each other by brazing, welding or the like.

1. A chemical thermal storage device comprising:
a reservoir that stores a reaction medium; and a reactor that is connected to the reservoir and heats a fluid, wherein the reactor includes a heat generation part that generates heat, and a heat exchange part made of a metal that forms a flow channel through which the fluid can flow and that transfers the heat generated in the heat generation part to the fluid, the reactor having a stack structure body having the heat generation part and the heat exchange part alternately stacked, the heat generation part has a thermal storage material that generates the heat upon chemical reaction with the reaction medium and desorbs the reaction medium upon reception of the heat from the fluid, and a metal casing that contains the thermal storage material, and the metal casing and the heat exchange part are joined to each other.
