摘　　要：对翅片管的强化传热过程进行了分析 ,建立了以单位传热量下翅片管的体积最小为目标函数的最优化数学模型 ,并对翅片管的最佳表面几何参数 (翅片高度、翅片节距、翅片厚度 )进行了分析 。The process of enhanced heat transfer for the f inned tubes was analyzed.The optimal mathematical model to minimize the volume of the fined tubes for given heat transfer capability was established.The optimal dimensions of the finned tubes(such as the length of the fins,the distance between neighbor fins and the thickness of the fin have been given.These are helpful to the design of heat exchanger with the fined tube.
