In order to study the wind load influence of different air-deflectors on a super-large cooling tower, the wind pressure distribution characteristics of the cooling tower with four cases are studied by wind tunnel test, the characteristics of the wind pressure include the average pressure, the fluctuating wind pressure, the extreme wind pressure and the peak factor, the influence of different air-deflectors on the overall and the local wind pressure distribution of the large cooling tower is obtained, the fitting formula of extreme wind pressure of cooling tower under different wind installations is presented. The result shows that three kinds of air-deflectors can effectively reduce the average wind pressure of the extreme pressure in the middle of cooling tower, the case four is best to reduce the RMS of the wind pressure in the upper part of the cooling tower. The peak factor values of the super-large cooling tower ring are different, the wind face is 3.29, the crosswind side is 3.41, the leeward side is 3.50.
