摘要

采用直接测温的方法

测定了新表面材料的滴状冷凝传热特性

并同国外滴状冷凝传热研究的结果进行比较.分析讨论了Cu-Cr表面和机械抛光表面传热性能的差异.对Cu-Cr和机械抛光两种表面进行了寿命实验

滴状冷凝现已超过8500小时.

Abstract

Heat transfer characteristics of the new surfaces were determined through temperature measurement

and the results obtained were compared with dropwise condensation studies from various sources. The differences in heat transfer between Cu-Cr and mechanical polishing surfaces were discussed. Life-time experiments were conducted on both Cu-Cr surface and mechanical polishing surface. Perfact dropwise condensation gave a life-time of over 8500 hours.
