Multifunctional compound air inlet control device of counterflow type natural ventilation cooling tower

The invention relates to a multifunctional compound air inlet control device of a counterflow type natural ventilation cooling tower. The multifunctional compound air inlet control device constituted by a certain number of air guide plates, air baffle plates and sound insulation plates is arranged outside the air inlet circumference of the cooling tower, wherein the multifunctional compound air inlet control device can improve air inlet uniformity of the cooling tower, improve the performances of the cooling tower, reduce the temperature of circulating water out of the tower and improve economy in operation of an unit through the air guide plates; by arranging the air baffle plates, the cooling tower can be prevented from being iced in cold winter; and by arranging the sound insulation plates, noise pollution at the periphery of the cooling tower can be further reduced.
