The excellent thermo performance of the cooling tower is considered as the precondition for efficient, safe and full-load operation of the turbine. In this paper, the cooling performance due to the effect of natural wind is discussed.The benefit originates from the integration technology between air inlet diversion and frost proofing is analyzed combining with a real case. It is found that the integration technology effectively improves the thermo performance of the cooling tower, the economical performance of the unit and the reduction of pollutant emissions.
