  "textContent": "A charging module includes: a housing, a rectifying plate, and a direct current conversion plate. The housing includes an upper housing and a lower housing that are fitted to each other. An air inlet and an air outlet are disposed on two sides of the housing. The rectifying plate is fixedly disposed on the upper housing. The direct current conversion plate is fixedly disposed on the lower housing. A plurality of power switching transistors are disposed on both the rectifying plate and the direct current conversion plate. There is a gap between the plurality of power switching transistors. The plurality of power switching transistors are disposed at a first end portion or a second end portion of the rectifying plate. The plurality of power switching transistors on the direct current conversion plate are disposed at one end portion of the direct current conversion plate. An air duct is disposed between the rectifying plate and the direct current conversion plate. The air duct is parallel to the rectifying plate and the direct current conversion plate. Two ends of the air duct are respectively connected to the air inlet and the air outlet. A flow path of an airflow in the air duct is in a straight line. According to embodiments of this application, in a working process, air resistance of the air duct in the charging module is small, a heat dissipation effect is good, noise is low, reliability is high, and costs can be reduced.",
