The invention discloses a charger heat dissipation system and a speed regulation strategy making method thereof. The charger heat dissipation system comprises an air duct, a rectification module and an exhaust fan. The air duct is provided with an air inlet and an air outlet; the rectification module and the exhaust fan are located in the air duct, the rectification module comprises at least one rectification module, and the peripheral wall of the rectification module is attached to the inner wall of the air duct; the detection component is used for acquiring current working parameters of the rectification module; and the controller is in communication connection with the detection component, a duty ratio characteristic function of the exhaust fan is pre-stored in the controller, and the controller determines the rotating speed of the exhaust fan according to the current working parameters and the duty ratio characteristic function and sends a control signal corresponding to the rotating speed to the exhaust fan. Through structure optimization, the rotating speed of the exhaust fan can be adjusted in real time according to the working condition of the rectification module of the charger, the power consumption is effectively reduced, and the noise problem is also improved.
