熔盐重力热管工质选择的初步实验研究

Preliminary Experimental Study of Working Fluid Selection in Molten Salt Gravity Heat Pipe

实验研究了熔盐重力热管工质的优选准则,提出以相容性、热稳定性及液相传输系数等为标准,来优选熔盐作为重力热管的工质。同时以液相传输系数为准则,分析了熔盐工质的表面张力、密度、粘度和汽化潜热的测量方法,初步提出熔盐重力热管工质的优选准则。

Experimental study on selecting working fluid for molten salt gravity heat pipe was implemented ; and having compatibility, thermal stability and liquid transfer coefficient based to select molten salt as the gravity heat pipe＇ s working fluid was proposed, including having liquid transfer coefficient taken to analyze molten salt＇ s surface tension, density, viscosity and the latent heat of vaporization so as to propose the princi- ple of selecting the working fluid of the molten salt gravity heat pipe.
