[0020] Explanation of the reference numerals in the drawings: 100 first heat exchange fin, 110 first corrugated structure, 200 second heat exchange fin, 210 second corrugated structure, 300 first positioning structure, 400 second positioning structure, 500 third positioning structure, 600 fourth positioning structure. Specific Embodiments

[0021] The following details the embodiments of the present utility model. Referring to Figures 1 to 4 , the embodiments of the present utility model provide a heat exchange module, including a first heat exchange fin 100 and a second heat exchange fin 200. The first heat exchange fin 100 and the second heat exchange fin 200 are placed face to face and connected to each other. The first heat exchange fin 100 and the second heat exchange fin 200 are respectively provided with a first corrugated structure 110 and a second corrugated structure 210. As Figure 4 shown, a gap is reserved between the first heat exchange fin 100 and the second heat exchange fin 200.

[0022] The heat exchange module is respectively provided with a first corrugated structure 110 and a second corrugated structure 210 on the first heat exchange fin 100 and the second heat exchange fin 200, so that both the first heat exchange fin 100 and the second heat exchange fin 200 can be used for heat exchange, greatly increasing the heat exchange area and improving the heat exchange performance. Of course, it should be noted that although the way of setting the corrugated structures on both the first heat exchange fin 100 and the second heat exchange fin 200 may reduce the convex height or concave depth of the corrugated structures, since the corrugated structures are set on both heat exchange fins, both heat exchange fins can be used for heat exchange. Therefore, the total heat exchange area is still greatly improved, the heat exchange range is wider, and the heat exchange performance is higher.

[0023] Further, a first positioning structure 300 is provided around the inner end face of the first heat exchange fin 100, and a second positioning structure 400 is correspondingly provided around the inner end face of the second heat exchange fin 200. The first positioning structure 300 is positioned and connected with the second positioning structure 400. The first positioning structure 300 and the second positioning structure 400 are arranged at the positions around, which neither affects the wind resistance nor can provide a guiding and positioning effect for the assembly of the first heat exchange fin 100 and the second heat exchange fin 200, making it easier to assemble the first heat exchange fin 100 and the second heat exchange fin 200. Further, among the first positioning structure 300 and the second positioning structure 400, one is a positioning protrusion and the other is a positioning groove, and the positioning protrusion is positioned and inserted into the positioning groove. For example, referring to Figure 1 , the second positioning structure 400 is a positioning protrusion, and referring to Figure 2 , the first positioning structure 300 is a positioning groove.

[0024] Further, a plurality of third positioning structures 500 are provided on the inner end face of the first heat exchange fin 100, and a plurality of fourth positioning structures 600 are correspondingly provided on the inner end face of the second heat exchange fin 200. The plurality of third positioning structures 500 are sequentially positioned and connected with the plurality of fourth positioning structures 600. It can not only further enhance the positioning effect between the first heat exchange fin 100 and the second heat exchange fin 200, but also play a role in isolating the air duct. At the same time, it can also make the distance between the first heat exchange fin 100 and the second heat exchange fin 200 more uniform, make the air volume of each flow channel more uniform, and strengthen positioning and flow disturbance. Further, among the third positioning structure 500 and the fourth positioning structure 600, one is a positioning protrusion and the other is a positioning groove, and the positioning protrusion is positioned and inserted into the positioning groove. For example, referring to Figure 4 , the third positioning structure 500 is a positioning groove, and the fourth positioning structure 600 is a positioning protrusion.

[0025] Furthermore, the first heat exchange fin 100 and the second heat exchange fin 200 are thermoformed parts. The first heat exchange fin 100 and the second heat exchange fin 200 have the same structure. A set of molds can be used to form the first heat exchange fin 100 and the second heat exchange fin 200, which is convenient for assembling the first heat exchange fin 100 and the second heat exchange fin 200 and avoids misassembly. When the structures of the first heat exchange fin 100 and the second heat exchange fin 200 are the same, referring to Figure 4 , the inner end face structure of the first heat exchange fin 100 is the same as the outer end face structure of the second heat exchange fin 200, and the outer end face structure of the first heat exchange fin 100 is the same as the inner end face structure of the second heat exchange fin 200. Referring to Figure 1 , the outer end face of the first heat exchange fin 100 is provided with a second positioning structure 400 and a fourth positioning structure 600. Referring to Figure 2 , the inner end face of the first heat exchange fin 100 is provided with a first positioning structure 300 and a third positioning structure 500. Similarly, referring to Figure 4 , the inner end face of the second heat exchange fin 200 is provided with a second positioning structure 400 and a fourth positioning structure 600, which is the same as the outer end face of the first heat exchange fin 100. The outer end face of the second heat exchange fin 200 is provided with a first positioning structure 300 and a third positioning structure 500, which is the same as the inner end face of the first heat exchange fin 100. It can be understood that the inner end faces of the first heat exchange fin 100 and the second heat exchange fin 200 refer to the sides where the first heat exchange fin 100 and the second heat exchange fin 200 are close to each other, and the outer end faces of the first heat exchange fin 100 and the second heat exchange fin 200 refer to the sides where the first heat exchange fin 100 and the second heat exchange fin 200 are far from each other.

[0026] Furthermore, both the first corrugated structure 110 and the second corrugated structure 210 are wavy corrugations. For the convenience of thermoforming the first heat exchange fin 100 and the second heat exchange fin 200, both the first corrugated structure 110 and the second corrugated structure 210 protrude upward by 0.95 mm and recess downward by 0.95 mm. Although the protrusion height and the recess depth are lower than those of the prior art, the first heat exchange fin 100 and the second heat exchange fin 200 in this heat exchange module can both be used to improve heat exchange, and the total heat exchange area is relatively large. Therefore, it still has good heat exchange performance.

[0027] An embodiment of the present utility model also discloses a heat exchanger, including the above heat exchange module, which at least has all the beneficial effects that the above heat exchange module can bring.
