摘要
分析了百叶窗翅片式微通道换热器的优缺点,以Fp/2、角度θ为输入变量,空气侧最小压降和最大换热量为输出优化目标,运用CFD软件Ansys建立数学模型,并将模型导入Mode FRONTIER优化软件,采用多目标遗传算法进行优化计算。优化结果表明,采用1.5~1.7mm的Fp/2、24°~26°的开窗角度θ时,空气侧压降及换热性能达到最佳组合。
The advantages and disadvantages of the louvered finned heat exchanger were analyzed in this paper. The value of Fp/2 and angle of the fin were used as input variables, and the airside minimalpressure drop and the biggest heat exchange as the output optimization goals. The mathematicalmodelbuilt with the CFD software Ansys was imported into the optimization software Mode FRONTIER, in which multi-objective genetic algorithm was used to realize optimization. The optimized results showed that when the value of Fp/2 is 1.5~1.7mm and the degree of the angle is 24~26, the airside pressure drop and the property of the heat exchanger willreach the best combination.
