초록
In the present numerical research, develop a high-efficiency fan model to improve the performance of the cooling fan, which accounts for a lot of weight in the efficiency of the cooling tower. For this purpose, analyze the shape of the existing cooling fan model and use CFD. The main variable set in the analysis of the cooling fan model is the pitch angle, and the range of the pitch angle was investigated in the range of 0° to 20°. The purpose of this research is to select the optimum driving condition by using CFD for setting the pitch angle that depends on the existing experience. The research results showed the best results when the pitch angle range was 15°~18°.
