Numerical simulation of louver fin surface flow and heat transfer and configuration optimization

Performs the three-dimensional numerical simulation and optimization for louver fin with tube-diameter of 9mm for a conditioner in detail, and puts forward the optimized structure parameters. Comparison shows that the optimization results in a decreased pressure drop across the heat exchanger and an improved comprehensive performance factor(CPF) when the facing velocity ranges from 0.25 to 4 m/s, and the heat exchanger volume is reduced by about 33% under given heat transfer rate and slightly higher CPF.
