Using the opened thermosiphon of 38x3 as experimental element and water as working fluid,the characteristics of dynamic low load boiling,stable severe boiling heat transfer coefficient and critical heat flux are gotten for the opened thermosiphon at the pressure of 0.02-0.1MPa and 0.1-0.8MPa respectively,which makes up the drawback that the opened thermisiphon has not yet accurate boiling heat transfer relationship formulas.

本文以工程上常用的Φ38×3的开口封底为实验元件，以水为工质，对开启式热管内的动态低负荷沸腾、稳态旺盛沸腾及临界沸腾特性进行系统的可视化实验研究，实验压力为0.02～0.8MPa，实验得出了Φ38×3的开口封底管在工作压力为0.02～0.8MPa和0.1～0.8MPa下的管内沸腾传热系数及临界热负荷计算关联式，弥补了开口封底管——这一新型传热元件尚无准确的沸腾换热关联式的缺陷。
