摘　　要：综述了固液界面能差效应强化冷凝传热的新机制及其对纯蒸气及含不凝气的蒸气冷凝传热过程影响的理论和实验研究进展.阐述了引入固液界面能差效应后的膜状冷凝、滴状冷凝和过渡状冷凝传热模型,及模型与实验数据的对比结果.介绍了利用固液界面效应强化纯蒸气和含不凝性气体的混合蒸气冷凝传热的强化技术.This paper reviewes the advances in the investigation of the solid-liquid-interfacial-energy- difference （SLIED） effect on the heat transfer processes of filmwise, transition （filmwise and dropwise co-existing） and dropwise condensation modes for pure vapor and mixture vapor in the presence of non-condensable gas. The heat transfer models with consideration of the SLIED effect of each condensation mode mentioned above are proposed. A comparison of the theoretical results and the experimental data is presented for confirming the significance of this novel mechanism for heat transfer enhancement. Other heat transfer enhancing technologies are also introduced.
