Water-cooling electric charger

Abstract

The invention discloses a water-cooling electric charger. A water-cooling piece is in a cylindrical shape, is arranged in a shell and can rotate along an axial line of the water-cooling piece, a motoris arranged in the shell and is used for driving the water-cooling piece to rotate, a cavity is formed in the water-cooling piece, cooling water is accommodated in the cavity, a heat conduction pieceis fixedly arranged on the shell and is arranged at an inner side of the water-cooling piece, the heat conduction piece props against the inner side of the water-cooling piece, a heat conduction silica gel piece is arranged on a surface of the heat conduction piece, an electrical appliance component is arranged on the heat conduction silica gel, no cooling hole is formed in the shell, rainwater and dust cannot enter the shell, so that the electrical appliance component in the shell can be enabled for normally work for a long time; heat generated by the electrical appliance component is sequentially conducted along the heat conduction silica gel piece and the heat conduction piece and is finally conducted to the water-cooling piece, the conducted heat is absorbed by the cooling water, so that the temperature of the electrical appliance component can be reduced; and moreover, the workpiece is continuously rotate during the working process, the cooling water flows in the cavity, and theheat absorption efficiency of the cooling water is improved.

Description

technical field [0001] The invention relates to the technical field of chargers, in particular to a water-cooled electric vehicle charger. Background technique [0002] In order to ensure the normal use of the electric vehicle, it is necessary to charge the electric vehicle in time when the electric vehicle lacks electric energy, that is, use the charger to connect the external power supply to charge the battery in the electric vehicle; The outer surface of the charger is equipped with heat dissipation teeth, heat dissipation holes and heat dissipation fans for heat dissipation, but after a period of use, a large amount of dust will accumulate on the circuit board of the charger, which greatly shortens the service life of circuit components and is easy to Cause a short circuit, causing potential safety hazards; and the existing chargers cannot solve the waterproof and moisture-proof problem, mainly because the heat dissipation holes will make water easily enter the inside of...
