Embodiment Construction
[0037] The present invention will be further described below in conjunction with accompanying drawing:
[0038] This embodiment includes a box body, a cooling fan 12 and a braking resistor 4. The cooling fan 12 and the braking resistor 4 are installed in the box body, and a fixing plate 8 for installing electrical components is arranged on the inner side of the back panel of the box body. The above are common structures in the prior art, and will not be repeated here.
[0039] The box body is a double-layer structure, and the two-layer box body is called the inner layer box body 2 and the outer layer box body respectively. When dissipating heat, the heat in the distribution box is transferred to the interlayer between the inner box body 2 and the outer box body through heat transfer, and then dissipated to the outside of the distribution box by the cooling fan 12 .
[0040] The inner box 2 is a cubic structure surrounded by steel plates, and the outer sides of the four vertic...
