The connecting piece 22 is located inside the control cabinet 1. The connecting piece 22 is fixedly mounted on the bottom end of the mounting piece 3 through a fixing piece 4, so that the connecting piece 22 can be fixed below the exhaust port of the exhaust fan 21. The fixing piece 4 is composed of a fixing frame 41 and a second screw The connecting piece 22 is composed of a bolt 42, a fixing frame 41 is fixedly sleeved on the outer surface of the top end of the connecting piece 22, there are two second bolts 42, the two second bolts 42 are threaded through the fixing frame 41, and the two second bolts 42 are threadedly connected to the mounting plate 31, so that the connecting piece 22 is fixedly installed on the bottom end of the mounting plate 31, four threaded holes are provided on both sides of the connecting piece 22, and the interiors of the eight threaded holes are threadedly inserted with exhaust pipes 23, and the outer surfaces of the eight exhaust pipes 23 are provided with a plurality of through holes, and the eight exhaust pipes 23 are connected to the exhaust port of the exhaust fan 21 through the exhaust fan 21. The suction force generated when the exhaust fan 21 is working can absorb the heat inside the control cabinet 1 through the through holes of the plurality of exhaust pipes 23 into the interior of the exhaust pipes 23, and then enter the connecting piece 22, and finally be sucked away by the exhaust fan 21 and discharged to the outside of the control cabinet 1, thereby achieving the purpose of heat dissipation inside the control cabinet 1.

[0017] Reference Figure 1 The control cabinet 1 is composed of a shell 11 and a support plate 12. There are eight support plates 12, four of which are welded to one inner wall of the shell 11, and the other four support plates 12 are welded to the other inner wall of the shell 11. The eight support plates 12 and the eight exhaust pipes 23 are staggered. The top ends of the eight support plates 12 can be used to install multiple electrical control components.
