Field of the Invention The present invention relates to an efficient heat exchanger for utilizing a hydrogen storage alloy, and particularly requires an efficient heat exchange such as a heat pump, heat storage, a hydrogen vehicle, and a fuel cell. It is suitable for use in the field.

交換器についてこれまで多くの提案がなされてきた。2. Description of the Related Art Hydrogen storage alloys have a wide range of applications such as storage and transport of hydrogen, heat pumps, heat storage, purification and separation of hydrogen, and production of hydrocarbons. Many suggestions have been made.

り替えて水素の吸蔵と放出を行っている。Among the heat exchangers, a hydrogen storage alloy is filled in a cylindrical pressure-resistant tube, and a cooling medium or a heating medium is passed through the outside of the tube. A type in which a cooling medium or a heating medium is filled and a cooling medium or a heating medium is passed through a pipe is known, and the storage medium is switched between the cooling medium and the heating medium at regular time intervals to store and release hydrogen.

A heat transfer fin is provided in the hydrogen storage alloy filling layer, or a heat transfer promoting member such as a metal sponge or a metal mesh is arranged.

とがむずかしく、実用上多くの問題がある。[0005] On the other hand, in a general cylindrical hydrogen storage alloy heat exchanger, it is necessary to reduce the thickness of the hydrogen storage alloy layer in order to improve the heat transfer. The amount of filling per bottle is reduced, and the number of tubes must be increased to compensate for this, which inevitably increases the weight. Also, when attaching heat transfer fins, it is necessary to increase the thickness to a certain extent in order to secure strength, which limits the weight reduction, and arranges heat transfer promotion members such as metal sponge and metal mesh. In such a case, it is difficult to obtain a lightweight, inexpensive material having good heat transfer performance, and it is difficult to increase the adhesion between these members and the tube wall, and thus there are many practical problems.

大きくなり、熱効率の低下をきたす。Further, in order to alternately store and release hydrogen, it is necessary to alternately supply a cooling medium or a heating medium to the outer vessel. However, in the conventional cylindrical heat exchanger, the body side is changed. Since it is structurally difficult to reduce the flow rate, the flow velocity decreases and the heat transfer coefficient cannot be increased. Attempts have been made to provide a baffle to improve this, but in this case, the sensible heat taken by the baffle itself increases, resulting in a decrease in thermal efficiency.

用範囲が制限されるのを免れなかった。Further, since the cylindrical heat exchanger has a large residence volume on the shell side, it takes a long time to switch or exchange the cooling medium and the heating medium, and a large sensible heat loss is caused by mixing the cooling medium and the heating medium. There was also a disadvantage. For these reasons, in order to improve the heat transfer performance, the cylindrical heat exchanger had to sacrifice weight reduction, and the use range of the heat exchanger was inevitably limited.

うに動作させるのが有利である。In the heat exchanger of the present invention, the hydrogen storage alloy filling portions 2, 2 ',... Are filled with the hydrogen storage alloy. The type, shape, grain size, etc. of the hydrogen storage alloy are not particularly limited. Instead, they can be appropriately selected and used according to the purpose of use. However, it is advantageous to use a fluorinated one in terms of simplification of the pressure resistance structure at the time of initial activation and stable use over a long period of time.
In order to exchange heat with the apparatus of the present invention, hydrogen gas is passed through the hydrogen storage alloy filling portion, and heat generated by hydrogen absorption is absorbed and recovered by the medium passing through the adjacent heat exchange medium flow path. Next, when the hydrogen storage alloy has finished storing hydrogen, a heating medium is passed through the adjacent heat exchange medium flow path to heat the hydrogen storage alloy to generate hydrogen, which is recovered. By repeating such an operation, cooling and heating of the medium or adsorption and desorption of hydrogen can be performed according to the purpose. When the hydrogen storage alloy filling section and the heat exchange medium flow path are provided in parallel, it is advantageous to operate the hydrogen gas flow and the heat exchange medium in countercurrent.

る。In the heat exchanger of the present invention, each of the hydrogen storage alloy filling portions is filled with a hydrogen storage alloy having a different characteristic, and a heat exchange medium having a different temperature is passed through a heat exchange medium flow path adjacent to the heat storage medium. In such a system in which hydrogen moves between two or more types of metal hydrides, complicated connection by piping can be omitted. Also, by measuring the pressure fluctuation on the hydrogen storage alloy side and forcibly controlling the pressure on the heat exchange medium side to be the same as the hydrogen pressure following the hydrogen pressure, the pressure applied to the flat plate can be reduced. Therefore, there is an advantage that the thickness of the flat plate can be reduced to reduce the weight.
