The paper specifies the construction of high efficiency fan, analyzes the factor of affecting efficiency and puts forward the principle of designing method. And the main assembly of the fan such as impeller, volute and diffuse is designed. On the basis of this, this paper is to simulate the internal flow field in impeller and volute of the fan under different operating conditions based on CFD theory and standard two-equation turbulent model and applying the flow calculation software CFX. And the details of flow field, the total pressure of fan and the efficiency are analyzed. Simulation results show that the efficiency of designed fan is high, the stream(flow)is equality.
