It consists of an inverter bridge, control logic, and filter circuits. Existing inverters tend to generate a lot of heat during use.

[0003] For example, CN212063853U discloses a low-power inverter with good heat dissipation performance, including an inverter body. The inverter body includes a shell, with mounting holes at both ends. A mounting plate and a fixing plate are respectively installed inside the mounting holes. The mounting plate and the fixing plate are fixed inside the mounting holes by fixing bolts. An exhaust fan is installed on the fixing plate. The main unit is arranged inside the shell. Connecting plates are welded to both sides of the main unit. A slide rail is welded to the inner wall of the shell. The slide rail has a fixing groove inside. A support plate is installed inside the fixing groove. The low-power inverter main unit with good heat dissipation performance is mounted on the slide rail of the shell through the connecting plates. It can move on the slide rail through the connecting plates, which facilitates quick completion of work during disassembly. It is convenient to use and has multiple functions.

[0004] However, in existing technologies, inverters generate a lot of heat when they are working. Excessive temperature will accelerate the aging of components, reduce their performance and lifespan, and even directly cause component damage. Currently, traditional inverters have poor heat dissipation and limited cooling effect, which affects the normal use of the device. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: a low-power inverter with good heat dissipation performance, including a main body 1. Guide blocks 16 are symmetrically fixedly connected to the upper and lower surfaces of the main body 1. The guide blocks 16 are engaged with a first support plate 2 via guide grooves 17. Second support plates 5 are symmetrically arranged between the two sets of first support plates 2. A plurality of equidistantly arranged first heat dissipation fins 3 are fixedly connected to the surfaces of both sets of first support plates 2. A first serpentine tube 4 is arranged in the middle of the plurality of first heat dissipation fins 3. A plurality of equidistantly arranged second heat dissipation fins 6 are fixedly connected to the surfaces of the two sets of second support plates 5. A second serpentine tube 4 is arranged in the middle of the plurality of second heat dissipation fins 6. The first serpentine tube 4 and the second serpentine tube 7 are fixedly connected by a connecting sleeve 8. An exhaust fan 15 is provided on the outer wall of the main body 1. The heat dissipation is achieved by a modular assembly method. The first serpentine tube 4 and the second serpentine tube 7 are installed through the connecting sleeve 8 and connected to an external circulation pump, so that the coolant circulates in the first serpentine tube 4 and the second serpentine tube 7 to liquid cool the inverter. At the same time, the natural heat dissipation of the first heat dissipation fin 3 and the second heat dissipation fin 6 is combined to accelerate the heat dissipation performance of the inverter. The first support plate 2 and the second support plate 5 are modularly assembled and spliced, which facilitates later maintenance and improves the overall practicality of the device.

[0023] like Figure 1-4 As shown, the upper and lower surfaces of the two sets of first support plates 2 are symmetrically provided with second positioning holes 10, and the upper and lower surfaces of the two sets of second support plates 5 are symmetrically provided with first positioning holes 9. The first positioning holes 9 and the second positioning holes 10 are located on the same horizontal plane. A first positioning rod 11 is inserted into the inner cavity of the first positioning hole 9 and the second positioning hole 10. The first positioning rod 11 is inserted through the first positioning hole 9 and the second positioning hole 10 to limit the position, so as to fix the second support plate 5 and the first support plate 2, prevent the device from loosening, and improve the stability of the device.

[0024] like Figure 1-4 As shown, the upper and lower surfaces of the two sets of first support plates 2 are symmetrically provided with third positioning holes 12 at the end near the second positioning hole 10, and the surface of each guide block 16 is symmetrically provided with fourth positioning holes 13. The third positioning holes 12 and the fourth positioning holes 13 are located on the same horizontal plane. A second positioning rod 14 is inserted into the inner cavity of the third positioning hole 12 and the fourth positioning hole 13. The second positioning rod 14 is inserted into the third positioning hole 12 and the fourth positioning hole 13 to limit the position of the first support plate 2, further preventing the device from becoming loose. The overall structure is simple, easy to disassemble and assemble, and suitable for widespread promotion.

[0025] like Figure 1-4As shown, both the first support plate 2 and the second support plate 5 are provided with shock-absorbing components on the side near the main body 1. The shock-absorbing components include mounting cavities 18, which are multiple in number and are opened on the surface of the first support plate 2 and the second support plate 5 near the main body 1. The inner bottom wall of the mounting cavity 18 is fixedly connected to the shock-absorbing plate 23 through the first shock-absorbing spring 19. A sleeve 20 is fixedly connected to the inner bottom wall of each mounting cavity 18 at the axis of the first shock-absorbing spring 19. The inner bottom wall of the sleeve 20 is fixedly connected to the connecting rod 22 through the second shock-absorbing spring 21. The end of the connecting rod 22 away from the second shock-absorbing spring 21 is fixedly connected to the shock-absorbing plate 23. When the main body 1 is impacted, the shock-absorbing plate 23 is compressed by pressure, compressing the first shock-absorbing spring 19 and simultaneously compressing the second shock-absorbing spring 21 through the connecting rod 22. This provides a certain safe buffer space when the main body 1 is impacted, improving the safety of the device and extending its service life.

[0026] Working principle: In use, the first support plate 2 is first fixed to the main body 1 by engaging the guide groove 17 and the guide block 16. Next, the second positioning rod 14 is inserted into the third positioning hole 12 and the fourth positioning hole 13 to limit the position of the first support plate 2. Then, the second support plate 5 is installed between the two sets of first support plates 2, and the first positioning rod 11 is inserted through the first positioning hole 9 and the second positioning hole 10 to limit the position, thus fixing the second support plate 5 to the first support plate 2 and providing all-round protection for the main body 1. The first serpentine tube 4 and the second serpentine tube 7 are installed through the connecting sleeve 8 and connected to an external circulation pump, thereby circulating the coolant in the first serpentine tube 4 and the second serpentine tube 7 to circulate the coolant. The inverter is cooled by liquid cooling, and the natural heat dissipation of the first heat dissipation fin 3 and the second heat dissipation fin 6 accelerates the heat dissipation performance of the inverter. The first support plate 2 and the second support plate 5 are modularly assembled, which facilitates later maintenance and improves the overall practicality of the device. The exhaust fan 15 installed on the outside of the main body 1 provides air cooling for the main body 1, which further improves the heat dissipation effect. When the main body 1 is impacted, the shock absorber 23 is compressed by pressure, which compresses the first shock absorber spring 19 and simultaneously compresses the second shock absorber spring 21 through the connecting rod 22. This provides a certain safe buffer space when the main body 1 is impacted, which improves the safety of the device, extends the service life of the device, and is suitable for large-scale promotion.
