The design of this utility model can effectively prevent particles such as dust and gravel from entering the cooling tower, ensure the normal operation of the equipment, extend the service life of the cooling tower, reduce maintenance costs, reduce manual intervention, improve operational stability, be environmentally friendly and energy-saving, reduce the amount of particles entering the cooling tower system, and reduce system energy consumption. However, there is a problem that the filler in this cooling tower is highly consistent, which makes the wind resistance of the filler in the inner zone larger, and the heat dissipation effect of the filler in the outer zone is not ideal. Utility Model Content
