[0025] like Figure 1 As shown, this embodiment provides an inverter with excellent heat dissipation performance, including an inverter body 1, four groups of support legs 2 are fixedly provided at the four corners of the bottom wall of the inverter body 1, and heat dissipation fins 3 and heat dissipation fans 4 are arranged on the bottom wall of the inverter body 1. The heat dissipation fan 4 is located on one side of the heat dissipation fins 3. The setting of the heat dissipation fan 4 and the heat dissipation fins 3 improve the overall heat dissipation efficiency. A dust cover 5 is arranged on the bottom wall of the inverter, and the dust cover 5 is arranged outside the heat dissipation fins 3 and the heat dissipation fan 4. Heat dissipation grooves 6 are opened on the four side walls of the dust cover 5, and dust nets 7 are installed in the heat dissipation grooves 6. The setting of the dust cover 5 can prevent dust accumulation on the heat dissipation fins 3 and the heat dissipation fan 4.

[0026] Specifically, see Figure 2-Figure 4In this embodiment, the dust cover 5 is a detachable structure on the inverter body 1; each set of support legs 2 is provided with a set of mounting grooves 8, and the mounting grooves 8 on the two sets of support legs 2 at the same end of the inverter body 1 are arranged opposite to each other, and four sets of mounting plates 9 are arranged at the four corners of the dust cover 5, and the mounting plates 9 are snap-fitted and installed in the mounting grooves 8. The convenient installation and removal of the dust cover 5 can be achieved by the cooperation of the mounting plates 9 and the mounting grooves 8; the height of the dust cover 5 is less than the height of the support legs 2, and the height difference is set on the dust cover 5 When the installation is completed, the upper surface of the dust cover 5 fits with the lower surface of the inverter body 1, and the lower surface of the dust cover 5 is in a suspended state to ensure the heat dissipation requirements; corresponding fixing holes are opened on the mounting plate 9 and the supporting legs 2, and a fixing mechanism is arranged on the bottom wall of the inverter body 1. There are two groups of fixing mechanisms symmetrically arranged, and the two groups of fixing mechanisms are respectively located on both sides of the dust cover 5, and each group of fixing mechanisms is arranged corresponding to the two groups of supporting legs 2 and the fixing holes of the mounting plate 9. Under the action of the fixing mechanism, the dust cover 5 can be stably connected to the supporting legs 2.

[0027] Specifically, see Figure 4 and Figure 5 In this embodiment, the fixing mechanism includes a fixing shell 10, a slide groove 11 is provided on the top wall of the fixing shell 10, and the slide groove 11 is connected to the inner cavity of the fixing shell 10. A fixing pin 12 is slidably provided on the side wall of the fixing shell 10 close to the supporting leg 2. One end of the fixing pin 12 located outside the fixing shell 10 is adapted to the fixing hole and is slidably arranged in the fixing hole. When the fixing pin 12 is embedded in the fixing hole, the mounting plate 9 can be stably fixedly connected to the supporting leg 2. The other end of the fixing pin 12 is fixedly connected to a force plate 13, and the force plate 13 is slidably arranged in the slide groove 11. A fixing spring 14 is sleeved on the fixing pin 12. The two ends of the fixing spring 14 are respectively connected to the inner wall of the fixing shell 10 and the force plate 13. The force plate 13 can be used to fix the fixing The pin 12 applies force, thereby realizing the position adjustment of the fixing pin 12 compared with the fixing hole of the mounting plate 9. When the fixing pin 12 is moved out of the fixing hole of the mounting plate 9, the dust cover 5 can be conveniently removed; the fixing pin 12 is provided with two groups at both ends of the fixed shell 10, and the force-applying plate 13 and the fixing spring 14 are arranged one by one with the fixing pin 12; a shielding plate 15 is fixedly provided on the upper end of the force-applying plate 13, and the shielding plate 15 is slidably arranged above the top wall of the fixed shell 10. The size of the shielding plate 15 is not less than the size of the slide groove 11. When the fixing pin 12 is embedded in the fixing holes of the supporting leg 2 and the mounting plate 9, the shielding plate 15 blocks the slide groove 11, and since the shielding plate 15 is located above the top wall of the fixed shell 10, it is more convenient to apply force to the fixing pin 12.

[0028] During specific use, the heat generated by the operation of the inverter body 1 is efficiently dissipated through the cooperation of the heat dissipation fins 3 and the heat dissipation fan 4, and the dustproof requirements of the heat dissipation fins 3 and the heat dissipation fan 4 are met through the provision of the dust cover 5, so as to prevent dust from accumulating on the heat dissipation fins 3 and the heat dissipation fan 4. When the heat dissipation fan 4 needs to be cleaned, it is only necessary to invert the inverter body 1, squeeze the two sets of shielding plates 15 toward the side close to each other, and the shielding plates 15 apply force to the fixing pin 12 through the force plate 13, and the free end of the fixing pin 12 moves out of the fixing hole. At this time, the fixing spring 14 is in a stretched state, and the fixing of the fixing pin 12 to the mounting plate 9 can be released. After releasing the fixing of the mounting plate 9, the dust cover 5 can be conveniently removed for cleaning. Only by cleaning the dust on the dust cover 5 can the heat dissipation be smooth and efficient.
