When heat exchange is required, the air inlet valve 5 is started to open the air inlet pipe 4, the fan 10 is started to drive the collecting box 8 and the air inside the serpentine heat exchange pipe 7 to flow and form negative pressure, and then external air enters along the air inlet pipe 4. The heat exchange mechanism 6 is started, water is injected into the sleeve 20, and the water is converted into water mist by matching with the spray head 21 and is sprayed into the air inlet pipe 4. After contacting with hot air, the water mist absorbs heat and evaporates, thereby reducing the air temperature, and finally is discharged along the serpentine heat exchange tube 7 and the exhaust tube 11. The water drops collected by the inner wall of the air inlet pipe 4 enter the collecting box 8 along the serpentine heat exchange pipe 7 for recovery.
