气体管壳式换热器传热强化技术研究(二)——关于强化传热管管型的讨论

Heat Transfer Enhancement of Gas Shell-and-Tube Heat Exchanger- Ⅰ. Rough Tubes

本文对几种用于气体传热强化的粗糙表面强化传热管管型进行了讨论,分别对它们在管内和管隙间的传热强化性能加以评价,对影响这些管型的传热强化性能的因素也作了分析。

Four rough tubes (spirally fluted tubc, transversally fluted tube, contracted-expanded tube and double side low fin tube) used for heat transfer enhancement are discussed. Heat transfer performance in the tube side and shell side of these tubes is evaluated and the factors influencing enhancement of heat transfer are analyzed.
