A silicone grease layer 10 is arranged between the box cover 3 and the connecting plate 11 . The box cover 3 transfers heat to the connecting plate 11 for heat dissipation through the fins 12 .

[0024] Before installing the connecting plate 11, a layer of silicone grease 10 is applied to the upper end of the box cover 3, and then the connecting plate 11 is installed on the upper end of the box cover 3. When the box cover 3 conducts heat to the connecting plate 11, the silicone grease layer 10 can fill the gap and air between the connecting plate 11 and the box cover 3, thereby increasing the heat conduction efficiency. The connecting plate 11 conducts the heat to the fins 12 at the upper end, and the air contacts the heat dissipation fins 12, absorbs the heat and takes it away, so that the fins 12 reduce the heat of the connecting plate 11 and cool the control box 1.
