Working principle: When using the device of this technical solution, the distribution box is installed in the specified position, and then the electrical appliances are installed on the outer wall of the fixed plate 12 inside the distribution box. During operation, the fixed plate 12 absorbs the heat generated by the electrical appliances, and the heat is transferred to the outside of the distribution box through the heat sink 14 arranged on the outer wall of the fixed plate 12. The blower 21 generates flowing air and transmits the flowing air to the heat sink 14 through the ventilation bin 2.
