Referring to fig. 1-2, the control box provided by the embodiment of the application includes a housing 10, a first power adapter 201, a second power adapter 202, a radiator and a first circuit board 50, where an air outlet 121 and an air inlet 131 are disposed on the housing 10.

By applying the control box of the embodiment of the application, the first power adapter 201, the second power adapter 202 and the first circuit board 50 are thermally connected with the radiator, and the heat dissipation channel 21 of the radiator is communicated with the air outlet 121 and the air inlet 131 to form a channel, after the heat generated in the working process of the electric elements of the first power adapter 201, the second power adapter 202 and the first circuit board 50 in the control box is absorbed by the heat dissipation channel 21, the channel is communicated up and down, so that good ventilation and heat dissipation can be realized, more heat can be dissipated, the heat is prevented from being concentrated and too dense in the center of the control box, and the heat dissipation performance is improved.

It should be noted that, the vertical projection area of the first circuit board 50 opposite to the heat sink spans the vertical projection areas of the first power adapter 201 and the second power adapter 202 opposite to the heat sink, and specifically, the vertical projection of the first circuit board 50 opposite to the heat sink may overlap with the vertical projection of the first power adapter 201 and the second power adapter 202 opposite to the heat sink by the same area, so that heat generated in the working process of the first circuit board 50 and heat generated by the first power adapter 201 and the second power adapter 202 are uniformly transferred to the heat sink, and therefore, the heat dissipation channel 21 of the heat sink dissipates, and the heat dissipation efficiency is improved.

In some embodiments, referring to fig. 2, the heat sink includes a first heat sink 101 and a second heat sink 102, the first power adapter 201 is thermally connected to the first heat sink 101, the second power adapter 202 is thermally connected to the second heat sink 102, the first circuit board 50 is thermally connected to the first heat sink 101, the second heat sink 102, and the first circuit board 50 spans the first heat sink 101, the second heat sink 102. Thus, two independent heat dissipation channels 21 can be formed, and the two independent heat dissipation channels 21 can emit almost the same heat at the same time, so that the heat dissipation efficiency is improved.

It should be noted that, the heat emitted by the first power adapter 201 and a portion of the heat emitted by the first circuit board 50 are transferred to the first heat sink 101, and the heat emitted by the second power adapter 202 and another portion of the heat emitted by the first circuit board 50 are transferred to the second heat sink 102, and since the first heat sink 101 and the second heat sink 102 both have one heat dissipation channel 21, two independent heat dissipation channels 21 can emit almost the same heat at the same time and are discharged through the air outlet 121, so that the heat dissipation efficiency is greatly improved.

Specifically, the thickness of the heat dissipation fins 22 may be 1.5 mm-2.5 mm, and the distance between every two adjacent heat dissipation fins 22 may be 6.5 mm-7.5 mm, so that as many heat dissipation fins 22 as possible can be distributed in the heat dissipation channel 21, and cold air can be blown through uniformly in the heat dissipation channel 21, wherein the thickness of the heat dissipation fins 22 may be 2 mm, and the distance between every two adjacent heat dissipation fins 22 is 7 mm, so that 10 heat dissipation fins 22 can be distributed in each heat dissipation channel 21, thereby increasing the heat dissipation surface area and rapidly guiding out heat to be convected away.
