The CFD simulation method for the aerodynamic performance of automotive cooling fan is presen-ted, and the effects of fan blade parameters on fan performance are investigated in-depth. Based on this, optimiza-tion designs of radiator fan and condenser fan for the engine of Chang-an V 805 base vehicle are conducted by simu-lation. The results of test verification show that on the premise of assured cooling performance, the result of reduc-tion in fan aerodynamic noise is achieved with the optimized design.
