Description

[0002] An electric vehicle charging pile is a device that replenishes power for electric vehicles. It can be installed in public places, commercial areas, residential areas, etc. to provide convenient charging services for electric vehicles. Electric vehicle charging piles are one of the important infrastructures for the development of electric vehicles. Common household AC charging piles may rely solely on natural heat dissipation. This method does not require additional cooling equipment and has the lowest cost, but the heat dissipation effect is relatively limited.

[0003] The places where AC charging piles need to be cooled are mainly the heat dissipation end and the connection plug of the charging pile. However, common AC charging piles are only designed with a fan for heat exchange at the heat dissipation end of the charging pile. Its connection plug will also generate a certain amount of heat under long-term high-load operation. If the heat dissipation at the connecting wire and the plug is poor, it may cause poor contact, increased resistance and other problems, thereby affecting the normal operation of the charging pile. Therefore, an AC charging pile with a cooling structure is needed to solve the above problems. Utility Model Content
