The invention discloses a charging pile with a good heat dissipation effect. The charging pile with the good heat dissipation effect comprises a charging pile shell, supporting legs are fixedly connected to four corners of the bottom of the charging pile shell, an exhaust fan is fixedly connected to the bottom of the charging pile shell, an air inlet cover communicates with the right side of the exhaust fan, the top of the air inlet cover penetrates through an inner cavity of the charging pile shell, and a temperature sensor is fixedly connected to the right side of the inner cavity of the charging pile shell. Through the cooperation of the charging pile shell, the supporting legs, the air inlet cover, the temperature sensor, a motor, a worm, rotating rods, worm wheels, fan blades, a watertank, a water adding pipe, a water pump, a connecting pipe and a cooling elbow pipe, the temperature of the inner cavity of the charging pile shell can be detected, if the temperature is too high, heat quantity in the inner cavity of the charging pile shell can be rapidly emitted, meanwhile, the inner cavity of the charging pile shell can be refrigerated to achieve the effect of rapid cooling, and the service life of the charging pile is prolonged.
