PURPOSE:To achieve the long time stabilization of heat reserve and taking-out capability and the reduction in sensible heat loss, by heat-treating the heat insulating material which covers a heat exchanger so as to remove water content and organic components which would be mixed in at the time of forming or preservation, and further coating the surface with a high heat insulating coat. CONSTITUTION:At the time of heat reserve and heat radiation, since the circumference of the cylindrical part of a heat exchanger is covered by a heat insulating material 9 which is coated by a heat insulating coat 8, there is no heat conduction between a cylindrical pipe 4 being the outer wall of the heat exchanger and the inner wall of a pressure container 1, and also there is no flow of hydrogen in he interior of the heat insulating material 9. Accordingly, the loss of sensible heat of the reaction due to convective heat transfer of hydrogen from the cylindrical pipe 4 to the pressure container 1 is significantly restrained. Furthermore, by removing completely water content and organic components by heat-treatment before heat insulating material 9, 10a and 10b are encaused in the pressure container 1, there is no fear of poisoning due to metal hydrites 7. Thus, the heat reserve and taking-out capability is stabilized extending over a long period of time, and further a metal hydride container having a good heat exchange efficiency can be obtained. |
