Abstract：In order to enhance the heat transfer performance of the air side of louver fin type air cool-er,four new variable angle louver fin structures are proposed in this paper.Based on computational fluid dynamics theory,a three-dimensional model was established to simulate the flow and heat trans-fer characteristics of four experimental groups and one control group when the louver angle was differ-ent in louver spacing and wind speed,and optimize the comprehensive performance factor to the maxi-mum.The results show that,compared with the traditional shutter fin structure of the control group,the heat transfer factor j of the variable angle shutter fin designed by the structure of experimental group 2 is increased by 4.95％～7.50％,the resistance factor f is increased by 4.94％～12.74％,and the comprehensive performance factor JF is increased by 3.28％～3.85％in the wind speed range of 2～6 m/s.The overall performance is better than the traditional rectangular louver fin structure;When Fp equal to 0.9 mm,JF of experimental group 2 was the largest.
