かるに一般に金属水素化物は熱の不良導体である
から、熱交換器全体としての性能は十分なものが
得られていない実情にある。
Metal hydrides absorb and absorb hydrogen depending on the temperature.
Since it devolatilizes, efficient heat exchange is required. However, since metal hydrides are generally poor conductors of heat, the performance of the heat exchanger as a whole is not satisfactory.

From the viewpoint of forming and processing the spiral fins, it is difficult to expect complete contact between the outer periphery of the fins and the inner surface of the metal hydride holding outer tube. Therefore, these spiral fins cannot transfer the heat flow from the wall surface of the metal hydride holding outer tube to the metal hydride by direct heat conduction.

がある。 Further, Japanese Patent Application Laid-Open No. 145601/1983 discloses a structure in which fins are attached to the inside of a metal hydride holding container parallel to the axial direction of the container. Since such axial fins cannot be expected to come into close contact with the inner surface of the holding container, it is not possible to expect an improvement in heat transfer performance through heat conduction, and there is a problem in that they are expensive to manufacture.
