Abstract
A vehicle-mounted power supply apparatus and a vehicle. The vehicle-mounted power supply apparatus includes a power conversion circuit, an upper-layer PCB board, a lower-layer PCB board, a bottom cover, and a radiator. The upper-layer PCB board and the lower-layer PCB board are configured to bear a plurality of power switching transistors of the power conversion circuit, so that the power conversion circuit is distributed more flexibly. The lower-layer PCB board and a plurality of transformers are fastened to a bottom plate of the bottom cover, and cooled by heat dissipation through a lower-layer cooling channel in the bottom cover. The upper-layer PCB board and the radiator are sequentially stacked above the lower-layer PCB board and the plurality of transformers, and cooled by heat dissipation through an upper-layer cooling channel in the radiator.
