Abstract
This invention discloses a heat exchanger comprising a compact of hydrogen adsorption alloy formed by a process of coating surfaces of fine particles of hydrogen adsorption alloy composed principally of a metal hydride with a dissimilar metal by plating and either by a process of compression molding of the coated alloy or by a process of filling a heat-conductive porous material with the coated fine particles of hydrogen alloy followed by a process of compression molding thereof. By this arrangement, it becomes possible to improve such disadvantages of conventional heat exchanger using hydrogen adsorption alloy as a decline of heat conductivity caused by micronization of the hydrogen adsorption alloy as a result of repeated uses or a decline of filling rate of the alloy caused by collapse and dispersion of the fine particles of the alloy compact eventually bringing about a decline of the heat exchanging function.
