High Quality Portable Evaporative Air Cooler, Water Cooling Fan

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.
