Heat dissipation device of new energy automobile charging pile power supply

Abstract

The invention relates to the technical field of new energy vehicles, and a heat dissipation device of a new energy automobile charging pile power supply. The heat dissipation device comprises a heat dissipation base and a water cooling device arranged on one side of the heat dissipation base, the heat dissipation base is provided with a cooling cavity and an electronic element containing cavity. Aheat dissipation element is arranged in the cooling cavity, the water cooling device comprises a heat dissipation water row communicated with the cooling cavity and a water pump used for circularly pumping cooling liquid between the cooling cavity and the heat dissipation water row, and an upper heat absorption plate and a lower heat absorption plate are arranged on the top face and the bottom face of the cooling cavity respectively in a sealed mode. In the present invention, the upper heat absorption plate and the lower heat absorption plate can quickly transfer heat of the power supply component to the heat dissipation base; the cooling liquid cooled by the heat dissipation water row enters the cooling cavity, absorbs heat on the heat dissipation base, becomes hot water and enters the heat dissipation water row again to be cooled, the cooled water enters the cooling cavity again to absorb heat, heat exchange of the heat dissipation base is completed through circulation, rapid heat dissipation of power supply components is achieved, and the service life of the power supply is prolonged.
