| Abstract: | In this paper,the cause of fan noise and the characteristics of noise component are expounded.Through the noise test,the size and distribution of noise are detected when the fan operates at a certain speed;the main components and type of the fan noise are clarified.The corresponding noise reduction measures are determined on the basis of the noise analysis,and then the noise reduction device is designed.The effective of the noise reduction device has been verified by through the noise test. |
