Electric vehicle charger with heat dissipation device

Abstract

The invention discloses an electric vehicle charger with a heat dissipation device. The electric vehicle charger with the heat dissipation device includes an electric vehicle charger body, the electric vehicle charger further includes a heat dissipation device; a heat dissipation tank is adopted by the heat dissipation device; the electric vehicle charger body is fixedly arranged in the heat dissipation tank; a gear ring is internally connected into the heat dissipation tank; a through hole is formed in the center of a triangular plate, and a circular protrusion is arranged in the through holein the mode extending into the tank; the circular protrusion sleeves a sun gear; a stabilizing bracket is internally connected into the sun gear; a motor is fixedly arranged outside the heat dissipation sink; one end of a rotating shaft is drivingly connected with the output shaft of the motor, and the other end of the rotating shaft is fixedly arranged at the center of the stabilizing bracket; three planetary gears are arranged; each planetary gear is fixedly arranged at the triangle position of the triangle plate respectively and is engaged with the sun gear and the ring gear respectively;each planetary gear is provided with blades in the axial direction of the heat dissipation tank; a plurality of heat dissipation holes are evenly formed in the side wall of the heat dissipation tank;and a wire connecting hold is formed in the heat dissipation tank. Heat dissipation to the electric vehicle charger is effectively realized.

Description

technical field [0001] The invention relates to the technical field of electric vehicle chargers, in particular to an electric vehicle charger with a cooling device. Background technique [0002] Electric vehicles are easy to operate, green and pollution-free, and are deeply loved by people. In order to ensure the normal use of the electric vehicle, it is necessary to connect the external power supply with the charger to charge the battery in the electric vehicle. Since the charger generates heat during charging, it will affect the charging performance and thus the service life of the charger, and even cause an explosion. Therefore propose a kind of electric vehicle charger with cooling device. Contents of the invention [0003] In view of the technical problems in the background technology, the present invention provides an electric vehicle charger with a heat dissipation device. [0004] To achieve the above object, the present invention provides the following technic...
