摘要

As microchannel gas cooler has advantages of compact structure, light weight and good heat transfer performance, it is widely used in the field of automotive air conditioning system. The air side performance of gas cooler has great influence on its overall heat transfer performance. Therefore, it is necessary to optimize the air side structure. Based on the response surface analysis, this paper optimizes the air side structure of staggered shuttle shaped fin gas cooler. The main structure sizes of staggered shuttle shaped fin considered in the analysis are half width a, half height b, column spacing c, row spacing d and length e. The DOE contains 27 design points and 30 refinement points. The high quality response surfaces of heat transfer coefficient, pressure drop and heat exchange are obtained by the second order polynomial method, and the influence of input parameters on output parameters was analyzed. The optimization objectives are the maximum heat transfer coefficient, the minimum pressure drop and the maximum heat transfer coefficient per pressure drop. Using Screening and MISQP method, the best candidate points for different single optimization objective are obtained. Multi-objective optimization of the three objectives is carried out by the MOGA method, and the first Pareto front with 251 candidate points are obtained.
