The system mainly comprises an air precooling system, a spray water precooling system and an evaporation and condensation system. Air enters the air pre-cooling system under the action of the first fan on the left side of the box body, enters the evaporation and condensation system after encountering cold, and water in the water tank enters the evaporation and condensation system after passing through the spray water pre-cooling system under the action of the booster water pump. Meanwhile, under the action of the second fan, air flows through the heat exchange tube bundles of the three systems respectively, and evaporation and heat absorption of water films outside the heat exchange tubes are promoted. The foam fin plates are embedded between the longitudinal heat exchange tube rows, so that the heat exchange area is effectively increased, a continuous water film is easily formed, and dry spots at the bottom of the water tube are eliminated. The three evaporation systems are in the same box body, and the structure is compact.)
