[0002] With the popularity and rapid development of electric vehicles, the demand for charging piles is also growing, especially high-power charging piles, which can significantly shorten the charging time and improve the charging efficiency, and are widely welcomed by users. However, high-power charging piles generate a lot of heat during operation. If the heat cannot be dissipated in time and effectively, the temperature of the electronic components inside the charging pile will be too high, thus affecting its performance and service life, and may even cause safety problems.

[0003] The heat dissipation methods in the prior art are often difficult to meet the requirements for high-power charging piles. For example, Chinese patent CN202410164833.5 discloses a high-power charging pile liquid cooling chiller and its control method, including: a shell, a heat exchanger, a circulation pump, a flow distribution module and a condensing coil, the shell is equipped with a heat exchanger, one end of the heat exchanger is connected to one end of the circulation pump, the circulation pump is connected to the other end of the heat exchanger through the flow distribution module, and a plurality of condensing coils are installed on the flow distribution module.

By arranging the condensing coils in the shell, the charging module is cooled, and the heat dissipation efficiency of the charging module is improved. However, the condensing coils are installed on the mounting frame in the shell, occupying the internal space; the heat dissipation efficiency of the chiller is low, and it can only be used on low-power charging piles; and after long-term circulation of the cooling water, impurities will be generated to breed bacteria, greatly reducing the heat dissipation efficiency.
