New energy automobile charging pile

The invention discloses a new energy automobile charging pile. The new energy automobile charging pile comprises a shell, a controller, a charging module and a charging gun, and further comprises a heat dissipation device. The heat dissipation device comprises a heat dissipation shell, an air inlet pipe and an air outlet pipe. The interior of the heat dissipation shell is divided into an air inletcavity and an air outlet cavity through a partition plate. A through hole is formed in the top of the heat dissipation shell and communicates with the air inlet cavity and the air outlet cavity. An air inlet and an air outlet are formed in the surface of the shell. The air inlet cavity communicates with the air inlet through a gas inlet pipe. An air pumping fan is arranged in the air inlet cavity. The air outlet cavity communicates with the air outlet through the air outlet pipe. An exhaust fan is arranged in the air outlet cavity. Grooves are formed in one end of the air inlet pipe and one end of the air outlet pipe
