Problems solved by technology
[0002] Traditional electrical cabinet heat exchangers use heat pipe technology. The heat exchanger is added with a heat-conducting medium to transfer heat through the phase change process of the medium. Using this method for heat exchange will make the processing technology of the heat-exchanging fins relatively complicated and the manufacturing cost high. , the heat transfer efficiency is not ideal

Embodiment Construction
[0009] The present invention will be further described below in conjunction with the accompanying drawings.
[0010] Such as figure 1 As shown, the present invention includes a heat exchange fin main body 1 . The upper surface and the lower surface of the heat exchange fin main body 1 respectively have a zigzag airfoil 2 structure. The distance between each group of airfoils 2 is 5mm to 10mm.
[0011] Through this design, the heat exchange fins can directly realize the air heat exchange inside and outside the electrical cabinet, the heat exchange process, the thermal resistance is small, and the heat transfer thermal resistance is 20%-30% lower than that of the traditional electrical cabinet heat exchanger using heat pipe technology .

The invention relates to an electric cabinet and in particular to a heat exchange sheet of an electric cabinet. The heat exchange sheet comprises a heat exchange sheet body and is characterized in that the upper surface and the lower surface of the heat exchange sheet body are of a saw-toothed wing-shaped sheet structure; and the distance between wing-shaped sheets in each group is 5-10mm. Compared with the prior art, the heat exchange sheet is simple in structure and convenient to manufacture, the heat exchange process is simple with little thermal resistance, and the heat resistance of heat exchange is reduced by 20-30% compared with that of a heat exchanger of a traditional electric cabinet based on the heat pipe technology.
Description
technical field [0001] The invention relates to an electric cabinet, in particular to a heat exchange sheet of the electric cabinet. Background technique [0002] Traditional electrical cabinet heat exchangers use heat pipe technology. The heat exchanger is added with a heat-conducting medium to transfer heat through the phase change process of the medium. Using this method for heat exchange will make the processing technology of the heat-exchanging fins relatively complicated and the manufacturing cost high. , the heat transfer efficiency is not ideal. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an electric cabinet body structure. [0004] In order to achieve the above purpose, the present invention designs a heat exchange fin for an electrical cabinet, including a heat exchange fin body, characterized in that the upper surface and the lower surface of the heat exchange fin body are respectivel...
