[0002] In the existing technology, the heat sinks in frequency converter equipment are based on each power segment, and the size and shape of the heat sinks for each power segment are different. That is, each model or each power segment has a specific size and shape of heat sink solution, which cannot be compatible and shared. This results in a situation of many types, inventory backlog and high maintenance costs, which increases the operational pressure on enterprises. Utility Model Content
[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide an assembly heat sink module for frequency converter products, which solves the problem that the types and specifications of heat sinks cannot be standardized in the prior art.
[0004] To achieve the above technical objectives, the technical solution of this utility model is as follows: A modular heat sink module for inverter products includes a first connecting part and a heat sink part, wherein: a first mating part and a second mating part are respectively formed on both sides of the first connecting part along a first direction; the first connecting part is connected to the heat sink part on one side along a second direction, and the first direction and the second direction are intersected; multiple modular heat sink modules for inverter products are sequentially connected along the first direction, so that a heat dissipation air duct is formed between the multiple heat sink parts, and in two adjacent modular heat sink modules for inverter products: the first mating part of one modular heat sink module for inverter products is interference-fitted with the second mating part of another modular heat sink module for inverter products.
[0005] Preferably, the assembled heat sink module for inverter products further includes a second connecting part, the second connecting part being connected to the heat sink on the side away from the first connecting part along the second direction, the second connecting part forming the first mating part and the second mating part on both sides along the first direction respectively, and in two adjacent assembled heat sink modules for inverter products: the first mating part connected to one second connecting part is interference-fitted with the second mating part connected to the other second connecting part.
[0006] Preferably, the number of the first mating part and the second mating part connected to the second connecting part is one.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0019] Please see Figure 1This embodiment provides an assembly heat sink module for inverter products, including a first connecting part 1 and a heat sink 2. The first connecting part 1 is connected to the heat sink 2, and the heat sink 2 is used to increase the contact area with air and quickly dissipate heat.
[0020] The first connecting portion 1 has a first mating portion 3 and a second mating portion 4 formed on both sides along the first direction. Both the first mating portion 3 and the second mating portion 4 are used to connect adjacent assembled heat sink modules for inverter products. Specifically, multiple assembled heat sink modules for inverter products are connected sequentially along the first direction, forming a heat dissipation channel between the multiple heat sinks 2. During use, a fan is directed towards the heat dissipation channel, blowing a large amount of air into it to remove heat from the heat sinks 2. In two adjacent assembled heat sink modules for inverter products, the first mating portion 3 of one module is interference-fitted with the second mating portion 4 of the other module. Preferably, in this embodiment, the first mating portion 3 is a boss, and the second mating portion 4 is a groove; that is, the first mating portion 3 and the second mating portion 4 are interference-fitted with a boss-groove structure. In a further preferred embodiment, a plurality of serrated structures 6 are provided on the outer side of the first mating part 3 along the first direction. When the first mating part 3 and the second mating part 4 are pressed together, the serrated structures 6 will deform and squeeze against the second mating part 4, effectively preventing the first mating part 3 and the second mating part 4 from separating. Its function is similar to that of an expansion screw. In order to facilitate the connection between the first mating part 3 and the second mating part 4, the side of the serrated structure 6 away from the second mating part 4 has a slope, and the serrated structures 6 are provided on both sides of the first mating part 3.
[0021] Preferably, the assembled heat sink module for inverter products further includes a second connecting part 5. The second connecting part 5 is connected to the side of the heat sink 2 away from the first connecting part 1 along the second direction. The second connecting part 5 forms a first mating part 3 and a second mating part 4 on both sides along the first direction, and in two adjacent assembled heat sink modules for inverter products: the first mating part 3 connected to one second connecting part 5 and the second mating part 4 connected to the other second connecting part 5 are interference-fitted. The number of first mating parts 3 and second mating parts 4 connected to the second connecting part 5 is not limited. In this embodiment, the number of first mating parts 3 and second mating parts 4 connected to the second connecting part 5 is one. Preferably, in the same assembled heat sink module for inverter products: the first mating part 3 connected to the first connecting part 1 and the second mating part 4 connected to the second connecting part 5 are located on the same side along the first direction, so their connection and force direction are also the same, which facilitates assembly.
[0022] The first connecting part 1 is connected to the heat dissipation part 2 along one side of the second direction, and the first direction and the second direction are intersecting. Preferably, in this embodiment, the first direction and the second direction are perpendicular to each other, which facilitates processing, manufacturing and assembly.
[0023] Preferably, the heat dissipation unit 2 includes two parallel heat dissipation fins 2a, both of which are connected to the first connecting part 1, and a heat dissipation airflow channel is formed between the two heat dissipation fins 2a. It should be noted that the number of heat dissipation fins 2a provided in each assembled heat dissipation module for the inverter product is not limited; providing two heat dissipation fins 2a can increase the connection strength between the first connecting part 1 and the second connecting part 5. Furthermore, to improve heat dissipation efficiency, the shape of the heat dissipation fins 2a can be designed as wavy to increase the contact area with air.
[0024] Preferably, the number of first mating parts 3 and second mating parts 4 connected to the first connecting part 1 are both two. This can improve the connection strength between different assembled heat sink modules used in frequency converter products.
[0025] It should be noted that the assembled heat sink module for inverter products can be extruded along a third direction, with the same process as aluminum profile extrusion. Therefore, only the manufacturing mold needs to be changed on the aluminum profile manufacturing equipment to manufacture the assembled heat sink module for inverter products. The material can also be aluminum, which is easy to process and relatively inexpensive. The third direction is perpendicular to both the first and second directions, meaning that the cross-sectional shape of the assembled heat sink module for inverter products remains consistent along the third direction, greatly reducing manufacturing difficulty. After manufacturing, the assembled heat sink module for inverter products can be cut in the third direction according to usage requirements to form the required length. Furthermore, different numbers of the assembled heat sink modules can be assembled in the first direction, greatly expanding its application range. The method of use is as follows: Within the power range, find a suitable height ratio, and determine a suitable width dimension according to a rule of increasing from small to large. Based on this, design a basic model. Then, design fitting and fastening structures on both sides of the model, one side being convex and the other being grooved. High-precision pressing is used to ensure a tight connection. This reduces the variety of radiator inventory and increases the demand for individual materials, thereby reducing procurement costs. It also allows suppliers to confidently stock up without worrying about inventory backlog caused by a wide variety of products.
[0026] In summary, the assemblies provided by this utility model for inverter products allow for easy assembly. Since the first mating part 3 and the second mating part 4 can be interference-fitted, during assembly, it is only necessary to align the first mating part 3 of one inverter product's assemblies with the second mating part 4 of another inverter product's assemblies with ...
[0027] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
