[0043] like Figures 2 to 4As shown, a plurality of partition units are fixedly connected to the inner wall surface of the first flow channel 111. In the present embodiment, eight partition units are provided in one first flow channel 111. The plurality of partition units are spaced apart along the extension direction of the first flow channel 111, and each partition unit can divide the first flow channel 111 at its location into two or more sub-flow channels 111a, so that after the heat exchange medium passes through the plurality of sub-flow channels 111a separated by a partition unit, it can be mixed in the area between two adjacent partition units, and then enter the plurality of sub-flow channels 111a separated by the next partition unit after being mixed.

[0044] Therefore, according to the heat exchange plate of the embodiment of the utility model, a plurality of spaced partition units are arranged in the first flow channel 111 to divide the first flow channel 111 into a plurality of sub-flow channels 111a, thereby effectively increasing the contact area between the heat exchange medium and the heat exchange plate body 10, and can improve the turbulence of the heat exchange medium, thereby effectively improving the heat exchange efficiency, and at the same time improving the structural strength of the heat exchange plate; and the heat exchange medium can be mixed after passing through the plurality of sub-flow channels 111a separated by a partition unit, and then enter the plurality of sub-flow channels 111a separated by the next partition unit after mixing, which is beneficial to reducing the temperature difference of the heat exchange medium, thereby helping to improve the temperature uniformity of the heat exchange plate.

[0046] That is to say, Figures 2 to 4 As shown, the heat exchange channel 11 mainly includes a plurality of first flow channels 111, a second flow channel 112 and a third flow channel 113, wherein the plurality of first flow channels 111 are respectively formed as long strip flow channels extending along the first direction, and the plurality of first flow channels 111 can be spaced apart along the second direction (for example, the length direction of the heat exchange plate body 10), the second flow channel 112 and the third flow channel 113 are respectively formed as long strip flow channels extending along the second direction, the second flow channel 112 is located at the first end of the plurality of first flow channels 111 and is connected thereto, and the third flow channel 113 is located at the second end of the plurality of first flow channels 111 and is connected thereto.

[0054] According to an embodiment of the present invention, connecting channels 114 are disposed between adjacent first channels 111 .

[0055] That is to say, Figures 2 to 4 As shown, a connecting flow channel 114 is provided between any two adjacent first flow channels 111, thereby further increasing the flow channel complexity of the heat exchange medium in the heat exchange plate, further increasing the contact area between the heat exchange medium and the heat exchange plate body 10, and effectively improving the temperature uniformity and heat exchange efficiency of the heat exchange plate.

For example, the liquid inlet hole 131 and the liquid outlet hole 132 are arranged at diagonal positions of the heat exchange plate, so as to ensure that the heat exchange medium can flow more evenly in the heat exchange flow channel 11, and the uniformity of heat exchange of the heat exchange medium can be ensured.

[0057] Furthermore, two liquid inlet holes 131 and two liquid outlet holes 132 are provided on one side of the heat exchange plate body 10 and are respectively located at diagonal positions of the heat exchange plate.

The plurality of fins 121 are respectively formed as sheet bodies extending along the first direction, and the plurality of fins 121 are distributed at intervals in the second direction, so that the first flow channel 111 at the location can be separated into a plurality of sub-flow channels 111a distributed along the second direction by the fins 121.

[0061] In the embodiment, the multiple fins 121 have a smaller flow resistance and greatly increase the contact area between the heat exchange medium and the heat exchange plate, effectively improving the heat exchange efficiency; at the same time, the fins 121 can also increase the turbulence of the heat exchange medium, further enhancing the heat exchange effect of the heat exchange plate.

[0067] In addition, since all the sub-channels 111a have the same cross-section, this also simplifies the design and manufacturing process of the heat exchange plate, reduces the production cost, and ensures the consistency of the structural strength of the heat exchange plate.
