[0002] Cooling towers are devices that cool water vapor into low-temperature water and discharge the system's waste heat into the atmosphere. They are used in industrial production. The amount of water lost by cooling towers each year is approximately 0.3% to 0.5% of the circulating water volume, of which a large amount of evaporation loss has always been a problem that cannot be ignored. Among them, the primary function of the cooling tower water collecting plate is to recover and recycle the water in the hot steam composed of water sprayed on the surface of the copper tube or the filler layer. As an important device in the cooling tower to reduce evaporation loss and wind loss, its structure and functional design determine its water collection effect. At present, due to its low water collection efficiency and high difficulty in cleaning and maintenance, the water resource waste problem of the water collecting plate needs to be solved urgently. The application of the quaternary bionic structure effectively solves this problem by enhancing the cooling effect, increasing the water collection efficiency, and realizing partial self-cleaning.
