The input end of the new energy vehicle charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug to charge the electric vehicle. When working, the heat generated is more than 3 times of the heat dissipation of the electric cabinet equipment, which requires the internal heat dissipation of the charging pile in time to ensure the daily work of the charging pile. PBM automobile cooling fan is the preferred product for cooling charging pile at present. The intelligent speed regulation function of PBM automobile fan can cool with the maximum air volume when charging at full speed, and reduce the speed when no-load to achieve energy saving and prolong the fan life.
