The double oblique corrugated water distribution filling is designed based on the step corrugation pattern, taking into account the cooling water flow path length in existing cooling tower fillings in China. It significantly increases the actual flow path of cooling water, markedly improving cooling efficiency. Simultaneously, it ensures more uniform water film distribution, expands the water-air contact area, and slows down water flow velocity. This type of filling component boasts high strength and is widely suitable for natural draft cooling towers and large mechanical draft cooling towers.
