[0019] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0020] See also Figure 1This embodiment provides an assembled heat sink module for inverter products, including a first connecting portion 1 and a heat dissipation portion 2, wherein the first connecting portion 1 is connected to the heat dissipation portion 2, and the heat dissipation portion 2 is used to increase the contact area with the air and quickly export the heat.
[0021] The first connecting portion 1 forms a first matching portion 3 and a second matching portion 4 on both sides along the first direction, and the first matching portion 3 and the second matching portion 4 are both used to connect adjacent assembled radiator modules for inverter products. Specifically, a plurality of assembled radiator modules for inverter products are connected in sequence along the first direction, so that a heat dissipation duct is formed between the plurality of heat dissipation portions 2. When in use, the fan is directed toward the heat dissipation duct, and the fan blows a large amount of air into the heat dissipation duct to take away the heat of the heat dissipation portion 2. In two adjacent assembled radiator modules for inverter products: the first matching portion 3 of an assembled radiator module for inverter products is interference-fitted with the second matching portion 4 of another assembled radiator module for inverter products. Preferably, in the present embodiment, the first matching portion 3 is a boss, and the second matching portion 4 is a groove, that is, the first matching portion 3 and the second matching portion 4 are interference-fitted with a boss-groove structure. Further preferably, a plurality of serrated structures 6 are arranged along the first direction on the outer side of the first mating part 3. When the first mating part 3 and the second mating part 4 are press-fitted, the serrated structure 6 will deform and be squeezed against the second mating part 4, thereby effectively preventing the first mating part 3 from being separated from the second mating part 4. 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 serrated structure 6 has a slope on the side away from the second mating part 4, and the serrated structure 6 is arranged on both sides of the first mating part 3.
[0022] Preferably, the assembled heat sink module for inverter products also includes a second connecting portion 5, the second connecting portion 5 is connected to a side of the heat sink 2 away from the first connecting portion 1 along the second direction, and the second connecting portion 5 forms a first matching portion 3 and a second matching portion 4 on both sides along the first direction, and in two adjacent assembled heat sink modules for inverter products: a first matching portion 3 connected to a second connecting portion 5 and a second matching portion 4 connected to another second connecting portion 5 are interference fit. The number of first matching portions 3 and second matching portions 4 connected to the second connecting portion 5 is not limited, and in this embodiment, the number of first matching portions 3 and second matching portions 4 connected to the second connecting portion 5 is one. Preferably, in the same assembled heat sink module for inverter products: the first matching portion 3 connected to the first connecting portion 1 and the second matching portion 4 connected to the second connecting portion 5 are located on the same side along the first direction, so their connection and force directions are also the same, which is convenient for assembly.
[0023] The first connection 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 arranged crosswise. Preferably, in this embodiment, the first direction and the second direction are arranged perpendicularly to facilitate processing, manufacturing and assembly.
[0024] Preferably, the heat dissipation part 2 includes two heat sinks 2a arranged in parallel, both heat sinks 2a are connected to the first connection part 1, and a heat dissipation duct is formed between the two heat sinks 2a. It should be noted that the number of heat sinks 2a provided in each assembled heat sink module for inverter products is not limited, and the provision of two heat sinks 2a can increase the connection strength between the first connection part 1 and the second connection part 5. In addition, in order to improve the heat dissipation efficiency, the shape of the heat sink 2a can be designed to be wavy to increase the contact area with the air.
[0025] Preferably, the number of the first matching portion 3 and the number of the second matching portion 4 connected to the first connecting portion 1 are both two, so as to improve the connection strength between different assembled heat sink modules for inverter products.
[0026] It should be noted that the assembled heat sink module for the inverter product can be extruded along the third direction, and its process is the same as the aluminum profile extrusion process. Therefore, it is only necessary to replace the manufacturing mold on the aluminum profile manufacturing equipment to manufacture the assembled heat sink module for the inverter product. Its manufacturing material can also use aluminum, which is easy to process and relatively low in price. The third direction is perpendicular to the first direction and the second direction, that is, along the third direction, the cross-sectional shape of the assembled heat sink module for the inverter product remains consistent, which greatly reduces the difficulty of processing and manufacturing. After manufacturing, the assembled heat sink module for the inverter product can be cut in the third direction according to the use requirements, so as to form an assembled heat sink module for the inverter product of the required length, and different numbers of assembled heat sink modules for the inverter product can also be assembled in the first direction, which greatly improves the scope of use. The method of use is: find the appropriate height ratio in the power range, determine the appropriate width size according to the rule from small to large, and design the basic model based on this. Then, design the matching connection and fastening structure on both sides of the model, one side is convex and the other side is concave, and high-precision pressing is used to make it tightly connected. It reduces the types of radiator inventory and increases the demand for a single material, thereby reducing procurement costs. At the same time, it also allows suppliers to prepare stocks with confidence without worrying about the backlog of goods caused by a wide variety of types.
[0027] To sum up, the present application provides an assembled heat sink module for inverter products. Since the first mating part 3 and the second mating part 4 can be interference fit, during assembly, it is only necessary to align the first mating part 3 of an assembled heat sink module for inverter products with the second mating part 4 of another assembled heat sink module for inverter products, and press them together with force to connect the first mating part 3 and the second mating part 4 together, and the assembly is completed. This connection method has high assembly efficiency and can quickly assemble different numbers of assembled heat sink modules for inverter products according to heat dissipation requirements. It is very convenient to use.
[0028] The above specific implementation methods of the present application do not constitute a limitation on the protection scope of the present application. Any other corresponding changes and modifications made according to the technical concept of the present application should be included in the protection scope of the claims of the present application.
