不可欠となる。(b) Prior art Various metals or alloys absorb a large amount of hydrogen at a density equal to or higher than that of liquid hydrogen to generate metal hydrides, and the generated metal hydrides change depending on temperature and hydrogen pressure. It is already known that hydrogen can be released and returned to the original metal or alloy by controlling the above conditions. Utilizing these properties, attempts have been made to apply metal hydrides to heat storage devices and hydrogen storage devices. In this case, the metal hydride requires a pressure-resistant container because the reaction proceeds under hydrogen pressure. In addition, a heat exchanger for transferring heat accompanying the hydrogenation reaction of metal hydrides is essential.

As seen in Publication No. 47989, a plurality of cylindrical bodies are arranged on a concentric axis, and the central cylinder is configured with a filter that allows hydrogen gas to pass through but does not allow metal hydride to pass through, forming a hydrogen inlet/output conduit, and the outside thereof. It has been proposed that a metal hydride is housed in a cylindrical body, and a heat exchange medium is allowed to flow through the cylindrical body outside the cylindrical body.

It is formed into an uneven shape along the direction, and the concave part is used as a guide inside the heat exchanger tube.
A plurality of semicircular baffles with a porous structure are arranged alternately at predetermined intervals, and an opening is provided in front of the baffle plates to form a heat medium flow path.

A large amount of heat can be transferred to the metal hydride, resulting in a high heat exchange capacity.

It consists of a container main body part 11 and a lid part 12 that house the container, and its flanges 11a and 12a are connected to bolts 3,
By joining with a nut 4, the inside is kept airtight and pressure-resistant. A heat transfer tube 5 is disposed that airtightly penetrates the main body side end surface 11b of the pressure vessel 1 and the approximate center of the lid part 12 to flow a heat medium. An inlet/outlet conduit 6 is attached.

ら効率良く熱伝達される。 With the above configuration, the heat exchange action is performed as follows. That is, during heat storage, the heat medium flowing inside the heat exchanger tube 5 in the direction of the arrow hits the baffle plate 9, a part of which passes around the baffle plate 9, and a part of which passes through the hole 9a of the baffle plate 9, and further passes through the baffle plate 9. As shown by the arrow F in FIG. 3, the heat exchanger meanders through the baffle plate 9 and the flat plate 10, and flows in the heat exchanger tube 5 in a turbulent flow. Moreover, since the inside of the heat exchanger tube 5 is formed in an uneven shape at this time, the heat of the heat medium is efficiently transferred to the heat exchanger tube 5 quickly and in large quantities. The heat transferred to the heat transfer tube 5 is further uniformly transferred to the metal hydride 2 via the heat transfer fins 8,
The metal hydride 2 is dehydrogenated efficiently. Further, the hydrogen gas generated at this time is stored in a hydrogen cylinder (not shown) from the metal hydride 2 through a hydrogen inlet/output pipe 6. On the other hand, during heat dissipation, hydrogen gas supplied from the hydrogen in/out conduit 6 to the metal hydride 2 via the metal hydride 2 is occluded by the metal hydride 2. The heat generated at this time is transferred to the heat transfer tube 5 via the heat transfer fins 8, and from there to the heat medium. Because it flows turbulently, heat is transferred efficiently.

Further, the heat transfer tube is housed in a pressure container with a heat insulating material interposed around its outer periphery, and the inside of the heat transfer tube that passes through the pressure container in an airtight manner is formed into an uneven shape, and a plurality of baffle plates are installed vertically at predetermined intervals.
