[First Embodiment]
A first embodiment will be described with reference to FIG. First, the configuration of the heat exchanger 10 according to the first embodiment will be described. As shown in FIG. 1, the heat exchanger 10 according to the first embodiment includes a regenerator material 11, a heat diffusion unit 12, a Peltier element 13, and fins 14.

  The cool storage material 11 is a phase change material that diffuses or absorbs cold heat and changes phase between a solid, a gel, and a liquid. Components of such a phase change material include components that have a relatively stable phase change temperature and change into a liquid phase at 20 ° C. to 60 ° C., for example, paraffin (melting point −12 to 44 ° C.), calcium chloride water Japanese hydrate (melting point 29.7 ° C.), sodium sulfate hydrate (melting point 32.4 ° C.), sodium thiosulfate hydrate (melting point 48 ° C.), sodium acetate hydrate (melting point 58 ° C.), etc. The component is appropriately selected from these components according to the heat holding temperature of the object to be cooled. For the purpose of finely adjusting the melting point of these components, an appropriate adjusting agent can be added to these components.

  The thermal diffusion unit 12 is provided between the Peltier element 13 and the fin 14. The thermal diffusion unit 12 is provided in contact with the Peltier element and is cooled by the Peltier element 13. The thermal diffusion unit 12 diffuses the cold heat of the Peltier element 13 and transmits it to the fins 14. The thermal diffusion unit 12 is a flat plate member having a first main surface 12A that comes into contact with the Peltier element 13 and a second main surface 12B on which the fins 14 are erected. In the present embodiment, an internal space is formed in the heat diffusion unit 12, and the regenerator material 11 is accommodated in the internal space.

  The Peltier device 13 is an electronic device in which heat is radiated on one heat radiating surface 13B and heat is absorbed (cooled) on the other heat absorbing surface 13A by passing an electric current. In the present embodiment, the heat absorbing surface 13A of the Peltier element is directly attached to the first main surface 12A of the heat diffusing unit 12. The heat radiation surface 13B of the Peltier element 13 releases heat to a heat radiation side heat exchange means (not shown).

  A plurality of fins 14 are erected on the second main surface 12B of the thermal diffusion unit 12. Each of the plurality of fins 14 extends in the same direction, and is arranged in parallel so that a predetermined gap 15 is formed in a direction orthogonal to the extending direction. And it is comprised so that the air which is the object which the heat exchanger 10 heat-exchanges may flow into the clearance gap 15 of the fin 14. FIG.

As shown in FIG. 20, the heat exchanger 180 according to the eighteenth embodiment differs from the heat exchanger 10 of the first embodiment in that it includes second fins 18 provided between adjacent fins 14. By providing the second fins 18 in the gaps 15 of the fins 14, the area in contact with the air flowing through the gaps 15 can be increased and the heat exchange performance can be improved.

  20 illustrates the configuration in which the second fins 18 are applied to the heat exchanger 10 of the first embodiment, but a plurality of fins 14, 24, 34, arranged in parallel as in the first embodiment. It can also be applied to the other embodiments described above comprising 44.

  The present embodiment has been described above with reference to specific examples. However, the present disclosure is not limited to these specific examples. Those in which those skilled in the art appropriately modify the design of these specific examples are also included in the scope of the present disclosure as long as they have the features of the present disclosure. Each element included in each of the specific examples described above and their arrangement, conditions, shape, and the like are not limited to those illustrated, and can be changed as appropriate. Each element included in each of the specific examples described above can be appropriately combined as long as no technical contradiction occurs.

  In the embodiment described above, the Peltier element 13 cools the heat diffusing unit 12 and stores it in the internal regenerator material 11, and the air flowing around the fins 14 using the cold heat of the Peltier element 13 stored in the regenerator material 11. Although the structure which cools was illustrated, the structure which heats air contrary to this may be sufficient. In this case, a heat storage material is accommodated in the heat diffusion unit 12 instead of the cold storage material 11. Further, the heat dissipation surface 13B of the Peltier element 13 is in contact with the first main surface 12A of the heat diffusing unit 12, the Peltier element 13 radiates heat to the heat diffusing unit 12, stores the internal heat storage material, and is stored in the heat storage material. The air flowing around the fins 14 is heated using the heat of the Peltier element 13.
