Distribution box, distribution box temperature adjusting method, battery pack and electric equipment

The invention provides a distribution box, a distribution box temperature adjusting method, a battery pack and electric equipment, the distribution box comprises a shell and a heating device arranged in the shell, the shell comprises a first part, a second part and a third part, the first part is in contact with the heating device, the second part is located above the heating device, and the third part is located above the first part. The third part is in non-direct contact with the heating device and outside the orthographic projection range of the heating device, at least part of the heating device is provided with a first heat radiation adjusting layer, and at least part of the surface of the third part is provided with a second heat radiation adjusting layer; the excitation mechanism is connected with the first heat radiation adjusting layer and the second heat radiation adjusting layer, and the excitation mechanism is used for changing the heat radiation rates of the first heat radiation adjusting layer and the second heat radiation adjusting layer. The heat distribution state in the distribution box can be changed, the temperature adjusting capability of the distribution box is improved, and the working efficiency of the distribution box is improved.
