Energy-saving high-voltage frequency converter cooling system

The invention discloses an energy-saving high-voltage frequency converter cooling system which comprises a water supply system, a filter, a high-voltage frequency converter chamber, a cooling tower water supplementing pool and a water storage tank. A plurality of high-voltage frequency converters are arranged in the high-voltage frequency converter chamber, and a surface air cooler is arranged onthe outer side of the high-voltage frequency converter chamber. Exhaust fans are arranged in the tops of the high-voltage frequency converters, exhaust outlets are formed in the tops of the high-voltage frequency converters and connected with an air inlet section of the surface air cooler through a hot air pipe, and a cold air pipe extending into the high-voltage frequency converter chamber is connected to an air outlet section of the surface air cooler. The water supply system is connected with a water inlet pipe of the surface air cooler through a water supply pipeline, and a filter is arranged on the pipeline betwe
