翅片管是一种强化换热的有效手段 ,在紧凑式换热器中翅片管已经得到了广泛的应用。但是波纹状纵向内翅片管却少有见报道。针对两种新型压缩机中冷器用的波纹状纵向内翅片高效换热器管 ,在实验研究的基础上用热力学第二定律对它们进行了火用分析 ,得出了一些有益的结论 ,同时也从理论上验证了实验的正确性 Finned tube is an effective means to enhance heat transfer, finned tube has been widely used in compact heat exchangers. However, corrugated longitudinal finned tube is rarely reported. Aiming at the corrugated longitudinal internal fin heat exchanger tubes used in the two new type of compressor intercoolers, based on the experimental research, they are analyzed by the second law of thermodynamics, and some useful conclusions are obtained. At the same time, It also validates the experiment’s correctness theoretically
