Composite fin and metal foam coupling sleeve hydrogen storage reactor

The invention discloses a composite fin and metal foam coupling sleeve hydrogen storage reactor, the structure is a cylindrical shell, the center is provided with a heat exchange sleeve, and the heat exchange sleeve comprises an inner heat exchange tube and an outer heat exchange tube; structurally-optimized longitudinal fins are evenly arranged in the circumferential direction of the outer heat exchange tube, a cavity between the longitudinal fins and the shell is filled with a mixture of metal hydride and metal foam, and the mixture bed layer is divided into two layers which are filled with metal foam respectively. A hydrogen inlet/outlet, a heat exchange fluid inlet, a heat exchange fluid outlet and a gas safety valve are arranged at the top end of the reactor, and a base and a vertical support are arranged at the bottom end; heat exchange fluid flows in from the top end inner heat exchange tube and flows out from the top end outer heat exchange tube, and hydrogen enters the bed layer through the material
