[0002] Special power supplies are devices that provide special power for electronic equipment. The battery pack used in them is composed of multiple batteries. Special power supplies are widely used in security, high-voltage power, medical, military, aerospace and other industries. Therefore, special power batteries are not only widely used to meet the needs of social industries, but also improve the urban environment. However, safety hazards also arise. When the special power battery pack is charging or discharging, the temperature will rise. When the temperature continues to rise to the critical point, an explosion will occur, which is very dangerous. A circulating air cooling device for a special power battery pack solves these problems well by installing a circulating refrigeration water tank, a heat dissipation fan and an exhaust fan.
