Power supply plate assembly for brake control unit

The utility model relates to the field of electromechanical manufacture, and aims to provide a power supply plate assembly for a brake control unit. The assembly comprises a power supply panel, a PCB, a first heat radiation sheet and a second heat radiation sheet. The PCB and the first heat radiation sheet are vertically disposed on the power supply panel. The PCB is parallel to the first heat radiation sheet. The PCB is provided with one or more electronic elements that are butted against the first heat radiation sheet. The beneficial effects are that the first and second heat radiation sheets are made of heat conduction materials, and the first heat radiation sheet is contacted with the heating electronic elements on the PCB to transmit heat to the power supply panel. The power supply panel radiates heat to the surroundings through heat radiation and convection. Compared with the conventional toothed blower heat device, the assembly is simpler in structure, smaller in weight, better in heat radiation effects and better in anti-shake performance.
