Beschreibung
Zusammenfassung:	The invention discloses an electric vehicle direct current charger device which comprises a case and an air supply device arranged in the case, an air outlet is formed in the side wall of the case, an air inlet is formed in the bottom of the case, and the air supply device comprises a fixing plate installed on the case and a reciprocating lead screw rotationally connected to the fixing plate. The reciprocating screw rod is sleeved with a sliding block in a penetrating mode, an air duct is fixedly connected to the sliding block, a cooling fan is arranged in the air duct, a driving motor is installed on the fixing plate, and an output shaft of the driving motor is in transmission connection with the reciprocating screw rod so as to drive the reciprocating screw rod to rotate. According to the invention, the air supply device is arranged in the case, so that heat generated in the case is cooled by air; in the heat dissipation process, the driving motor drives the reciprocating screw rod to rotate and drives the
