Industrial cooling fans generate strong airflow, forming a powerful wind cycle in tall spaces, quickly expelling hot air and moisture, and introducing fresh air, effectively reducing indoor temperature. Built in water or other cooling medium, providing the necessary humidity for evaporation through a water spray system or wet curtain. When hot air passes by, the water in the cooling medium evaporates and absorbs heat, thereby reducing the air temperature.

The working principle of water evaporative cooling fan is based on the phenomenon of heat absorption through evaporation. When water evaporates, it changes from a liquid state to a gas state, which requires absorbing a large amount of heat to lower the temperature of the surrounding environment. The evaporative cooling fan extracts water through a circulating water pump and evenly sprays it onto the evaporative filter layer. When outdoor hot air enters the evaporative cooling medium, it undergoes sufficient heat exchange with water molecules, absorbs heat through water evaporation, and cools down. Finally, it is pressurized by a low-noise fan and sent indoors to achieve indoor cooling.
