Specifically, the number of the heat exchange monomers of the heat exchange module 20 can be set to 1, 2, 3, 4, etc., and the heat exchange monomers can be specifically set according to actual design and use requirements, which is not specifically limited in this embodiment.
Specifically, the peripheral side of the first heat exchanging fin 231 and the first flange 2311, and the peripheral side of the second heat exchanging fin 232 and the second flange 2321 may be connected by welding, or may be integrally formed. Preferably, in order to ensure the sealing performance between the first plate 231 and the first flange 2311 and between the second plate 232 and the second flange 2321, in this embodiment, the periphery of the first plate 231 and the first flange 2311 and the periphery of the second plate 232 and the second flange 2321 are integrally formed.
Specifically, the first flanging 2311 and the second flanging 2321 are connected in a brazing mode, so that the sealing effect is achieved while the first flanging 2311 and the second flanging 2321 are connected.
More specifically, each heat exchange unit is adjusted by the energization state of the semiconductor layer 222 to achieve a heat transfer state of the medium between the medium channel 241 of the first heat exchange plate 221 and the medium channel 241 of the second heat exchange plate 223, that is, after the semiconductor layer 222 is energized, the P-type units and the N-type units inside the semiconductor layer 222 are arranged in a staggered manner, so that the surfaces of the two sides of the semiconductor layer 222 form a cold end and a hot end respectively, and then the heat exchange units transfer heat with the heat exchange plates on the two sides of the semiconductor layer 222, thereby finally achieving a cooling/heating effect. Moreover, the heat exchanger can perform bidirectional heat exchange, that is, the surfaces on the two sides of the semiconductor layer 222 are controlled to form a cold end or a hot end respectively by controlling the power-on state of the semiconductor layer 222, so that the semiconductor layer 222 can refrigerate or heat any heat exchange plate on the two sides of the semiconductor layer 222.
It should be noted that the first flanges 2311 of the first plate 231 and the second flanges 2321 of the second plate 232 can respectively increase the strength of the first plate 231 and the second plate 232 in the thickness direction of the heat exchanger. For being platelike heat exchanger fin, the thickness that is bowl-shaped structure's first heat exchanger fin 231 and second heat exchanger fin 232 can set up is thinner, and then when guaranteeing heat exchanger plate intensity requirement for the heat exchanger plate is lighter-weighted more. Meanwhile, when the medium flows in the heat exchange plate, the thinner heat exchange plate can effectively reduce the heat required by the heat exchange plate to reduce the thermal resistance and the heat loss during the heat exchange between the heat exchange plate and the semiconductor layer 222, and the heat exchange performance of the heat exchanger is improved.

When the heat exchanger plates are connected in the first heat exchange unit 211 in a screwed or riveted manner, a sealing member needs to be disposed between the guide pipe 252 and the second heat exchange plate 232 of the first heat exchange plate 221 in the first heat exchange unit 211, so as to ensure the sealing performance between the guide pipe 252 and the second heat exchange plate 232 of the first heat exchange plate 221 in the first heat exchange unit 211. Therefore, in order to reduce the number of sub-components of the sealing member of the heat exchanger, the two flow guide pipes 252 in this embodiment are preferably connected to the second heat exchange fins 232 of the first heat exchange plates 221 in the first heat exchange unit 211 by welding.

Compared with a rigid material, the support plate 261 is made of an elastic material, so that the support plate 261 can deform to a certain extent when being extruded to better support the second heat exchange plate 232 of the second heat exchange plate 223 in the two heat exchange units. Since there is a space between the two heat exchange cells, that is, the first boss 253 and the second boss 2511 are formed in the thickness direction of the heat exchanger, the compression amount of the support plate 261 is the same as the sum of the sizes of the first boss 253 and the second boss 2511 in the thickness direction of the heat exchanger.
