摘　　要：主要研究了纵向翅片管的传热计算流程及工程应用。根据纵向翅片管的基本传热机理,系统深入地总结了纵向翅片管在不同传热条件下换热系数的计算方法,提出了纵向翅片管换热器的设计流程;通过具体工程实例,纵向翅片管换热器的设计理论得到验证,同时计算结果表明,与传统的光管相比,纵向翅片管传热系数高,设备传热性能好,是一种行之有效的节能途径,具有良好的应用前景。This paper focus on heat transfer calculating procedure and application of longitudinal finned tube. Based on the radical heat-transfer mechanism of longitudinal finned tube, the method of calculate the convective heat-transfer coefficient of longitudinal finned tube under dif- ferent heat transfer conditions is concluded systematically and in-depth knowledge and the design method flow of longitudinal finned tube heat exchanger is put forward. Though the design of specific project, the design theory is verified, and the results also show that the longitudinal finned tube is higher in its heat transfer coefficient compared to the traditional tube. Therefore the longitudinal finned tube heat exchanger has a higher heat transfer property, and the application of longitudinal finned tube is an effective energy-saving way which has an extensive prospect.
