[0017] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0018] like Figure 1-3As shown, a variable frequency drive cabinet comprises a variable frequency drive cabinet 1 and a connecting column 2, wherein the connecting column 2 is symmetrically fixedly connected to the bottom of the variable frequency drive cabinet 1, the bottom of the connecting column 2 is fixedly connected to a base 101, the outer wall of the connecting column 2 is fixedly connected to a heat dissipation clamp 201 in an array, an air bin 202 is fixedly assembled between two connecting columns 2 and located at the bottom of the variable frequency drive cabinet 1, a heat dissipation fan 203 is symmetrically fixedly assembled on the top of the air bin 202, heat dissipation holes 204 are opened in an array on both sides of the air bin 202, an arc cover 205 is symmetrically fixedly connected between the two connecting columns 2 and located on both sides of the air bin 202, and the arc cover 205 is arrayed around the body The arc cover 205 is fixedly connected with a heat sink 206, and the outer walls at both ends of the arc cover 205 are symmetrically fixedly connected with baffles 207, and the baffles 207 are provided with air outlet holes 208 in an array manner. The outer wall of the arc cover 205 and located between the two baffles 207 are integrally provided with an arc channel 212, and one side of the baffle 207 and located on the outside of the arc channel 212 is fixedly connected with a column 209, and the middle of the column 209 is rotatably connected with a rotating circle 210, and the outer wall of the rotating circle 210 is fixedly connected with a brush 211 for rotating in the arc channel 212, and one end of the rotating circle 210 is electrically connected to the electrical circuit inside the base 101.

The heat dissipation clamp 201 and the heat sink 206 are used to assist in absorbing heat. Furthermore, the arc-shaped curves of the arc cover 205 and the arc-shaped channel 212 and the horizontal opening of the baffle 207 can largely avoid the adhesion of catkins, and the rotating circle 210 drives the brush 211 to rotate through the internal electric wire of the heat dissipation clamp 201.
