If there is a description of first, second, it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the sequence of indicated technical features.

[0035] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0036] The heat dissipation structure of the first aspect of this utility model includes a main structure 100, heat dissipation blades 200, and first connecting members. The heat dissipation blades 200 are installed in the main structure 100, and the main structure 100 is provided with mounting grooves 110. Multiple heat dissipation blades 200 are provided, and each heat dissipation blade 200 is installed in the mounting groove 110. Each heat dissipation blade 200 is connected to the main structure 100 through multiple first connecting members. Currently, the heat dissipation structure on the gearbox housing is usually a single unit. However, a single unit heat dissipation structure is prone to air blockage during die casting, leading to poor molding of the heat dissipation blades 200 and a low yield rate. By separating the single unit heat dissipation structure into a main structure 100 and heat dissipation blades 200 connected by connecting members, the processing difficulty can be effectively reduced, and the yield rate of the finished product can be improved.

[0037] Furthermore, refer to Figure 1 , Figure 2 As shown, the surface of the heat dissipation blade 200 in this embodiment is provided with an exhaust groove 210. Along the length direction of the exhaust groove 210, the exhaust groove 210 includes a first groove segment 211, a second groove segment 212 and a third groove segment 213. The second groove segment 212 is disposed between the first groove segment 211 and the third groove segment 213 to connect the first groove segment 211 and the third groove segment 213. The depths of the first groove segment 211 and the second groove segment 212 are different, and / or the depths of the second groove segment 212 and the third groove segment 213 are different. The surface of the heat dissipation blade 200 is provided with an exhaust groove 210, which allows the gas in the die casting process to be discharged from the mold through the exhaust groove 210, thereby improving the molding structure and increasing the yield. The relationship between the depths of the first groove segment 211, the second groove segment 212, and the third groove segment 213 can be that the depths of the first groove segment 211 and the second groove segment 212 are different, but the depths of the first groove segment 211 and the third groove segment 213 are the same; or the depths of the first groove segment 211, the second groove segment 212, and the third groove segment 213 are all different. The first groove segment 211, the second groove segment 212, and the third groove segment 213 with different depths are designed to suit the environment of the gearbox housing. Generally, the closer the groove is to the gearbox housing, the more likely it is to become clogged during die casting. Therefore, it is preferable to set the first groove segment 211 to be the deepest and the third groove segment 213 to be the shallowest. The first groove segment 211 is located on the first side of the width direction of the heat dissipation fin 200, and the third groove segment 213 is located on the second side of the width direction of the heat dissipation fin 200. The first side of the width direction of the heat dissipation fin 200 is installed in the mounting groove 110 to reduce the probability of clogged air during die casting.

[0038] Further, on the basis that the depth of the first groove section 211 is greater than the depth of the third groove section 213, it is further preferred that the depth of the second groove section 212 is less than the depth of the first groove section 211 and greater than the depth of the third groove section 213, that is, in the heat dissipation structure of the embodiment, the depth of the first groove section 211 is greater than the depths of the second groove section 212 and the third groove section 213, and along the width direction of the heat dissipation structure, the depths of the first groove section 211, the second groove section 212 and the third groove section 213 decrease in turn, so that the probability of air blockage in the process of pressure casting can be avoided while the manufacturing difficulty is effectively reduced and the structural strength of the heat dissipation fin 200 is retained.

[0039] In the embodiment of the utility model, refer to Figure 2 As shown in the figure, the first groove section 211 and the third groove section 213 are arranged in parallel and at intervals along the length direction and the width direction of the heat dissipation fin 200, and the second groove section 212 is arranged between the first groove section 211 and the third groove section 213, the first groove section 211 and the third groove section 213 are both straight sections, and the second groove section 212 is provided with a bending portion. The first groove section 211 and the third groove section 213 are arranged in parallel and at intervals along the length direction and the width direction of the heat dissipation fin 200, so that the coverage area of the exhaust groove 210 can be effectively improved, and the second groove section 212 has a bending portion, so that the structural strength of the heat dissipation fin 200 can also be improved.

[0040] In the embodiment of the utility model, in order to further reduce the probability of air blockage of the heat dissipation fin 200 in the process of pressure casting, the heat dissipation fin 200 of the embodiment is provided with a plurality of exhaust grooves 210, and the plurality of exhaust grooves 210 are arranged at intervals along the length direction of the heat dissipation fin 200; in order to ensure the structural strength of the heat dissipation fin 200, there is a minimum spacing between the plurality of exhaust grooves 210, and the heat dissipation fins 200 of different sizes or types will also be different, and thus the minimum spacing between the plurality of exhaust grooves 210 will also be different.

[0041] In the embodiment of the utility model, a plurality of heat dissipation fins 200 are installed side by side in the installation groove 110; the plurality of heat dissipation fins 200 include two end plates 201 and at least one intermediate plate 202, and the at least one intermediate plate 202 is arranged between the two end plates 201; the side of the end plate 201 facing the intermediate plate 202 is provided with an exhaust groove 210, and the two sides of the thickness direction of the intermediate plate 202 are both provided with an exhaust groove 210. As shown in the figure, two end plates 201 are provided, and the side of each of the two end plates 201 facing away from each other is not provided with an exhaust groove 210, so that the side of each of the two end plates 201 facing away from each other will not have the problem of air blockage in the process of pressure casting, and thus the side of each of the two end plates 201 facing away from each other is provided with an exhaust groove 210, so as to reduce the manufacturing cost. As shown in the figure, Figure 1 Figure 1 ​There are three intermediate plates 202, but the specific number of intermediate plates 202 can be selected according to the overall size of the heat dissipation structure.
