Abstract
A heat exchanger using two hydrogen storage alloys, including: a tubular housing member disposed in a horizontal position; a vertical partition plate extending axially within the housing member for partitioning the inside space of the housing member into two, first and second reaction zones in which the first and second alloys are contained, respectively, to form an upper space above each alloy; first and second heat-exchange tubes disposed in the first and second reaction zones, respectively, and arranged so that first and second fluids may be passed therethrough for indirect heat exchange with the first and second alloys, respectively; openings provided in the vertical partition plate at least at positions so that the upper space in the first and second reaction zones are in fluid communication with each other; and a plurality of vertically extending gas passages provided in each of the first and second reaction zones, and each being in fluid communication with the upper space, whereby hydrogen gas released from one of the first and second alloys can efficiently diffuse in the other alloy.
