SWITCH CONTROL ELECTRICAL BOX AND POWER DISTRIBUTION METHOD

WIPO Patent Application WO/2022/198746

A1

Disclosed in the present invention are a switch control electrical box and a power distribution method. The switch control electrical box comprises a housing. A conductive slat used for supplying power to MOS transistors in a centralized manner is embedded on a circuit board in the housing. Therefore, the MOS transistors serving as switches in the switch control electrical box can be compactly mounted on the circuit board, such that the switch control electrical box is small in size while having a plurality of switch control circuits; and when the switch control electrical box is used on an electrical device such as a vehicle, the occupied space is small, and the mounting is more flexible. Because the power distribution method in the present invention relates to supplying power in the centralized manner by means of the conductive slat, the heating of the switch control electrical box is mainly concentrated on the conductive slat. By providing a conductive slat heat sink on one side of the housing, most of the heat generated by the switch control electrical box can be dissipated in time; and the conductive slat is erected on the conductive slat heat sink in a rib form, which is more conducive to heat dissipation, thereby preventing failure caused by overheating during use and prolonging the service life.
