Design Method of Cooling Fan for Noise Reduction and Noise Radiation Prediction Method of Cooling Fan

摘要

The present invention is designed to design an axial fan based on basic design specifications such as air flow rate, pressure rise, and motor rotation speed, and also to predict the degree of noise generated at the operating point at the same time with designing. And a method for predicting noise radiation of a cooling fan.;The present invention makes it possible to obtain a cooling fan capable of minimizing noise generation so that the noise of the cooling tower can be reduced to an optimal state and the ambient noise can be predicted so that the cooling tower can be used at the time of noise-.
