[0021] A charging pile refers to a device installed in public places or private parking lots for charging electric vehicles, hybrid vehicles, etc. The charging pile is usually composed of a shell, a power module 2, a control module and a charging socket. At present, during the use of the charging pile, the internal electronic components will continuously generate heat, causing the temperature inside the shell to gradually rise. Therefore, the charging pile shell is generally equipped with a special air inlet 6 and an air outlet 7, and a fan is used to continuously send out the heat for dissipation.

[0022] However, in winter, the heat dissipation channel on the surface of the shell will introduce cold air when the outside temperature is low. The low temperature will affect the battery and electronic components of the charging pile, reducing their working efficiency and life. In order to solve this problem, this solution proposes the following embodiment to fully and clearly describe the technical solution.
