Axial fans are widely used in the field of computer CPU heat ventilation and air conditioning, and so on, to improve the efficiency of fans and stability operations, in-depth study of the fans internal three-dimensional flow field details is necessary.This paper selected a two-dimensional airfoil to compute, using the Fine/Turbo software of the Belguim company NUMECA, and validated the univ-ersality of CFD technic. In the base of the result, the article brung a guide vane with the twisted blade axial fans for the CPU fan, the properties of the entire flow range of properties were simulated in different flow conditions. and analyzed the three-dimensional viscous flow, including an average week to pressure, secondary flow. The results showed that not only qualitative proved that the performance of the hump-shaped curve, also reached the condition of the flow field of quantitative information.This provided a basis to the heory and practice for Axial fans.
