摘要

为了提高板翅式散热器的传热性能,采用遗传算法对锯齿翅片的结构参数进行了多目标优化。根据优化结果建立了散热器单元流道三维物理模型,采用计算流体动力学的方法对其温度场进行了仿真研究,得到了新翅片的传热因子、摩擦因子和综合性能评价因子。仿真结果表明:优化后翅片的传热性能得到了提高;铜翅片的传热性能优于铝翅片的。通过风洞试验验证了仿真结果的有效性。

Abstract

In order to enhance heat transfer performance of plate-fin radiator,multi-objective optimization was carried out to the structural parameters of the serrated fin based on the genetic algorithm. According to the result of optimization,threedimensional physical model of the channel was built. The temperature field was investigated by the method of CFD. The heat transfer factor,friction factor and comprehensive performance evaluation factor of fin were obtained. The simulation results show that the heat transfer performance of the optimized fin was improved. Heat transfer performance of copper fin is better than that of aluminum fin. The validity of the simulation result is verified by wind tunnel test.
