What is Cooling Fan structural principle ?

"Cooling Fan" continuously withdrawing the water tank with circulating pump and uniformly sprayed on the filter layer is formed by evaporation of water distribution systems, outdoor hot air into the evaporative cooling medium in the evaporative cooling medium CELdek (special honeycomb material shaped filter layer, so that the cooling effect is more ideal, "cooling fan" high-tech patent product) within the full heat exchange with water, heat and water evaporation to cool the cool, clean air pressurized by the low-noise fan into the interior, "cooling Fan" in the room of hot air into the room, so as to achieve the purpose of cooling interior.
