Experimental Research for Performance and Noise of Small Axial Flow Fan

概要

Small axial flow fans are commonly used to cool personal computers or workstations. Although various studies have been carried out to improve the performance and reduce the noise of larger axial flow fans, few cases have been released about small fans. This paper investigates the influence of design parameters of an impeller, such as the camber of the blade, the maximum camber point of the blade, the cross sectional structure of the blade, the skew angle of the blade and the roundness of the blade edge on performance characteristics and noise.
