In this paper, by the method of the CFD simulation, the 3D inner flowing field of the fan is analyzed. According to the analysis result, a optimization design plan is put forward. The design result shows that air volume improves 11%, and acoustic noise is reduced about 2 dB(A). The experiment result shows that testing air volume improves 3%~5% and acoustic noise is reduced about (1~4) dB(A). The feasibility of the optimization design plan is validated through experiment and CFD simulation methods; the optimization scheme saves the costs of research and development, and abridges the period of research and development.
