System and method for realizing active heat dissipation of voltage regulation converter by utilizing ram air

The invention discloses a system and method for achieving active heat dissipation of a voltage regulation converter through ram air. The system is mainly composed of a ram air shunting channel, a speed brake, an air drying and dehumidifying device, an air door controller, an air door executing mechanism and a control system. According to the method, ram air at the front end of a pod duct is shunted through a ram air shunting channel, the air speed is reduced through a speed brake, moisture in the air is removed through a drying and dehumidifying device, and two paths of dry heat dissipation airflow are obtained; the air door controller sends a control signal to the air door execution mechanism by receiving an internal temperature signal of the converter collected by the control panel, so that the angle and direction of the execution mechanism in the channel are changed, the flow speed and direction of heat dissipation airflow are adjusted, and active heat dissipation of the voltage regulation converter is ach
