[0026] The present application will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present application. Any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present application.

[0027] To clearly illustrate the technical solution of this application, the following definitions are provided: Figure 1 The directions shown are front, back, left, right, top, and bottom. In this application, the length direction of the heat sink 100 refers to... Figure 1 The left and right directions in the middle, the width direction of the heat sink 100 refers to Figure 1 The front-to-back direction in the figure, and the height direction of the radiator 100 refer to... Figure 1 The up and down directions in the middle.

[0028] To address the shortcomings of existing technologies, firstly, this application provides a heat sink 100, such as... Figure 1 As shown, the radiator 100 includes: a radiator body 11, which is used to install heat dissipation components. In this embodiment, the heat dissipation components include at least an upper heat sink 12 and a lower heat sink 13.

[0029] like Figure 2 As shown, the upper heat sink 12 consists of a plurality of heat sinks disposed on the second side of the radiator body 11, extending upward along the radiator 100. An air duct 14 is formed between any two adjacent heat sinks in the upper heat sink 12 for heat dissipation of the radiator 100. Furthermore, a plurality of welding grooves 111 are provided on the second side of the radiator body 11, the number of welding grooves 111 corresponding to the number of upper heat sinks 12. The plurality of heat sinks on the second side are respectively disposed in the welding grooves 111 by welding, thereby securely mounting the upper heat sink 12 onto the radiator body 11.

[0030] This application achieves rapid installation of the upper heat sink 12 by pre-setting a welding groove on the second side of the heat sink body 11 and using brazing, thereby improving production efficiency and making the installation of the heat sink more secure and stable.

[0031] The lower heat sink 13 consists of a plurality of heat sinks disposed on the first side of the radiator body 11. The lower heat sink 13 extends in the downward direction along the radiator 100 and is disposed on the outside of the radiator 100. In the lower heat sink 13, an air duct 14 is formed between any two adjacent heat sinks for heat dissipation of the radiator 100.

[0032] In this embodiment, the radiator body 11 is made of thermally conductive material. The first side and the second side are opposite sides of the radiator body 11. The upper heat sink 12 and the lower heat sink 13 are respectively disposed on opposite sides of the radiator body 11. The heat absorbed by the upper heat sink 12 is conducted to the lower heat sink 13 through the radiator body 11. The lower heat sink 13 dissipates the heat to the external environment to achieve the heat dissipation function.

[0033] As one implementation, the lower heat sink 13 located on the first side of the heat sink body 11 is integrally formed with the heat sink body 11. On the one hand, the integral formation of the lower heat sink 13 with the heat sink body 11 can enhance the stability of the overall structure of the heat sink 100 and avoid the heat sink from becoming loose under complex working conditions. On the other hand, the integral formation of the lower heat sink 13 with the heat sink body 11 can optimize the heat conduction path and improve the heat dissipation performance of the heat sink 100.

[0034] As one implementation, the weld groove 111 located on the second side of the radiator body 11 is integrally formed with the radiator body 11. The weld groove 111 integrally formed with the radiator body 11 ensures the stability of the radiator 100 structure and reduces the problems that may occur due to the separation of the weld groove 111 from the radiator body 11, such as loose connection and affected heat dissipation effect.

[0035] As one implementation method, during the manufacturing process of the radiator 100, a lower heat sink 13 is formed on the first side of the radiator body 11 through an extrusion profile process, expanding the heat dissipation area and enabling heat to be quickly dissipated through the lower heat sink 13 on the first side; and a weld groove 111 is formed on the second side of the radiator body 11 to ensure seamless integration between the weld groove 111 and the radiator body 11, thus guaranteeing the structural stability of the radiator 100. The extrusion profile process reduces processing steps, improves the production efficiency of the radiator 100, and enhances the tightness of the connection between the lower heat sink and the weld groove 111 and the radiator body 11.

[0036] As one implementation method, such as Figure 3 As shown, the air duct 14 on the first side of the radiator body 11 extends in a direction parallel to the air duct 14 on the second side of the radiator body 11. The upper heat sink 12 on the second side of the radiator body 11 absorbs heat from the surrounding air and conducts the heat through the radiator body 11 to the lower heat sink 13 on the first side of the radiator body 11. Air flows through the air duct 14 and passes through the lower heat sink 13, thereby dissipating the heat in the lower heat sink 13 to the external environment.

[0037] As one implementation method, such as Figure 4As shown, the direction of extension along the air duct 14 is defined as the length direction of the heat sink. The upper heat sink 12 on the second side of the heat sink body 11 has the same length, which facilitates the installation of the heat sink, ensures the regularity of the structure of the heat sink 100, and increases the area of ​​the upper heat sink 12, thereby improving the heat dissipation capacity of the heat sink 100.

[0038] Optional, such as Figure 5 As shown, the second side of the radiator body 11 is provided with at least two types of upper heat sink fins 12 of different lengths, which improves the flexibility of heat sink installation and meets the needs of different layouts within the radiator 100. By providing heat sinks of different lengths, installers can adjust the layout according to the specific layout within the radiator 100. For example, in areas with ample space, longer upper heat sink fins 12 can be installed to increase the heat dissipation area and improve heat dissipation efficiency; while in areas with limited space, shorter upper heat sink fins 12 can be selected to avoid interference with other components, ensuring that the entire heat dissipation system can adapt to the internal space layout and fully utilize its heat dissipation performance to ensure stable operation of the equipment.

[0039] As one implementation method, such as Figure 6 As shown, the length of each upper heat sink 12 on the second side of the radiator body 11 is less than the length of the lower heat sink 13 on the first side of the radiator body 11. This reduces the internal space occupied by the upper heat sink 12 without affecting the overall heat dissipation effect, avoids the installation of other components due to the excessive size of the upper heat sink 12, and facilitates the internal layout design of the radiator 100.

[0040] In one implementation, the extension direction of the weld groove 111 is parallel to the extension direction of the air duct 14, and the weld groove 111 is at least partially located in the central region of the radiator body 11.

[0041] Specifically, in combination Figure 1 and Figure 5 In this application, the extension direction of the weld pool and the extension direction of the air duct are parallel to the left-right direction. This application defines... Figure 1 The left and right directions shown are the length directions of the radiator body 11. In this application, the middle section of the radiator body 11 along the length direction is defined as the central region of the radiator body 11.

[0042] The welding groove 111 is at least partially located in the central area of ​​the radiator body 11, allowing installers to flexibly adjust the position of the heat sink fins according to different internal layout schemes of the radiator 100. For example, when the layout space inside the enclosure near the radiator body is limited, the installation position of the upper heat sink 12 can be adjusted appropriately, such as moving it slightly to the left before welding it into the welding groove, leaving sufficient space for the left side layout inside the enclosure. In this way, the radiator can be adapted to enclosures with different layouts, facilitating the installation and welding of heat sink fins according to actual needs, and solving installation problems caused by layout differences.

[0043] As one implementation method, the upper heat sink 12 on the second side of the radiator body 11 is formed by stamping sheet metal. While meeting the heat dissipation performance requirements of the radiator 100, the production cost of the radiator 100 is reduced. Moreover, stamping sheet metal is highly efficient and can be mass-produced quickly, thereby increasing the production speed of the radiator 100.

[0044] According to the above description, the radiator 100 provided in this application has a plurality of heat sinks arranged on opposite sides of the radiator body 11, with an air duct 14 formed between the heat sinks on each side. The air flows evenly along the air duct 14 to achieve the heat dissipation function. The upper heat sink 12 is installed on the radiator body 11 through a weld groove 111, which simplifies the assembly process, improves the production efficiency of the radiator 100, and facilitates the maintenance and replacement of the upper heat sink 12. Through the extrusion profile process, the weld groove 111 is integrally formed with the lower heat sink 13 and the radiator body 11, reducing the processing steps and lowering the production cost of the radiator 100.

[0045] Secondly, this application also provides an inverter, including a housing and a heat-generating device located inside the housing. The inverter includes the heat sink 100 described above. The heat sink body 11 is fixedly connected to the housing. The housing is provided with a window. A heat sink on the first side is located outside the housing, and a heat sink on the second side extends into the housing through the window. The heat sink 100 is used to provide heat dissipation for the inverter.

[0046] Specifically, the inverter uses the heat sink provided in the embodiments of this application. The inverter housing has a window, and the upper heat sink 12 of the heat sink extends into the housing through the window. The upper heat sink 12 exchanges heat with the air inside the housing and conducts the heat to the lower heat sink 13. The lower heat sink is located outside the housing and can exchange heat with the outside air, thereby realizing the heat from inside the housing to the outside of the housing, which can effectively reduce the temperature inside the housing.
