The cooling tower generates a certain amount of noise during operation, and a noise reduction device needs to be installed. At the same time, the cooling tower is also a ventilation device. The exhaust fan on the top of the equipment needs to exhaust air, and an exhaust silencer needs to be installed at the exhaust port. There is air inlet on the side of the equipment, and an air inlet silencer needs to be installed on the noise reduction device or an open hole needs to be opened. In addition, the installation area of ​​the cooling tower often has decoration requirements, requiring the outer surface of the entire noise reduction device to meet the decoration requirements of the environment in the area, and the equipment and its connected pipes should not be clearly visible to the naked eye.

[0003] At present, there are aluminum square tubes or ventilation curtain walls on the market to shield and enclose cooling towers, which solves the problems of ventilation and decoration, but has no noise reduction effect. One is to install noise reduction devices to reduce the impact of noise propagation in cooling towers, solving the problems of ventilation and noise pollution, but these noise reduction facilities are often unable to coordinate with the regional environment and cannot solve the decorative problem; the third is to combine the first two, not only to do noise reduction treatment, but also to decorate the outside of the noise reduction facilities, but it causes double investment, and the arrangement of the silencer sheets of the air inlet silencer and the exhaust silencer cannot be consistent with the decorative materials, making the decorative layer an obstacle to the air vents, thereby greatly increasing the ventilation resistance and possibly affecting the normal operation of the equipment. The fourth is to use a folded plate type ventilation and silencer curtain wall, which has decorative, ventilation and noise reduction functions, but it can only solve the decorative treatment of the vents on the facade of the cooling tower noise reduction device, and cannot solve the decorative treatment of the noise reduction device exhaust vents, sound insulation panels, doors and windows and open areas.
