One end of the heat dissipation channel 8 is covered at the hot air outlet of the electrical module in the box body 1, and the other end of the heat dissipation channel 8 is connected to the heat dissipation outlet 7. When the electrical module inside the box body 1 is working, the hot air generated can be discharged through the heat dissipation channel 8 for heat dissipation, which plays a good heat dissipation role. In addition, the heat dissipation channel 8 is composed of a plurality of plate bodies spliced ​​together, the interface of the heat dissipation channel 8 remains unchanged, and the electrical module is replaceable. The design of the heat dissipation channel 8 can be changed according to the different electrical modules used inside in actual conditions, that is, the number of plates and the splicing combination method and shape are changed. The heat dissipation channel 8 is easy to change, and is more suitable for machines such as welding machines that may use different electrical module units due to different needs.

[0049] Reference Figure 1 , Figure 4 , Figure 8 and Fig. 9 A heat exhaust pipe 81 is fixedly installed in the heat dissipation channel 8, one end of the heat exhaust pipe 81 is connected to the muffler in the box body 1, and the other end of the heat exhaust pipe 81 is located at the hot air outlet.

The box body 1 can be assembled in parts and then assembled in its entirety, thereby optimizing the assembly process. When the box body 1 needs to be moved, the operator can operate by holding the handle 5. When the electrical module inside the box body 1 is working, the hot air generated can be discharged through the heat dissipation channel 8 for heat dissipation, thereby achieving a good heat dissipation effect. The heat generated by the muffler can be discharged through the heat exhaust pipe 81. Multiple cold air inlets 9 can perform multi-directional cooling on the inside of the box body 1, thereby improving the heat dissipation effect.
