However, the evaporative coolers designed are basically wet evaporative coolers. With the migration of large chemical industries to the northwest in recent years, evaporative coolers specially designed for the northwest climate are rare. The climate characteristics of the northwest are half a year in winter and half a year in spring, summer, and autumn. The winter is cold, windy, and the temperature difference between day and night is large. Antifreeze is the main consideration in winter production. The dry and wet evaporative cooling device is designed for this climate characteristic.

[0031] To sum up, in actual use, in winter when the temperature is low, the cooling box 10 connected to the water tank 12 is stopped and the water in the water tank 12 is drained. The number and power of the fans 21 are determined according to the outlet temperature of the closed circuit of the material to be cooled. When the temperature is low enough, the fans 21 can be stopped and only air cooling is used for cooling. At the same time, the motor 32 is turned on to drive the light tube 4 and the fin tube 3 to rotate, so that the cooling process is more uniform.

[0032] In spring, summer and autumn when the temperature is high, water is added to the water tank 12 and the cooling box 10 connected to the water tank 12 is turned on, so that the water in the water tank 12 is sprayed out from the spray head 1, and the spray water contacts the light tube 4 and the fin tube 3 to cool down. The fan 21 can be turned on at the same time to form a local negative pressure in the shell 18, accelerate the air flow and water evaporation, and improve the cooling efficiency. The power of the fan 21 can be controlled and the spraying amount can be controlled by controlling the pump body in the cooling box 10, thereby saving water resources and electric energy.
