Abstract：In order to improve the heat dissipation performance of commercial vehicle cooling modules and achieve lightweight cooling modules, computational fluid dynamics method is used to analyze the effects of the height of the heat dissipation strip, wave peak distance, and window opening angle of the radiator on heat dissipation performance. The optimal performance parameters of the cooling module are obtained, and the radiator structure is optimized based on simulation results. Wind tunnel tests and vehicle thermal balance tests are conducted on the optimized radiator. The results show that the mass of the optimized radiator is reduced by 17.9% and heat dissipation performance is improved by 1%-8%. Optimizing the height of the heat dissipation strip, peak to peak distance, and window opening angle can improve the heat dissipation performance of the cooling module, achieve lightweight, and reduce production costs.
