大型中温热管性能的试验研究

Experimental Study of the Performance of Large sized Medium temperature Heat Pipes

对萘和甲基吡硌烷酮两种充装工质的大型中温热管进行的性能试验所得数据进行了分析，比较了两种热管的起动及传热性能等方面的特性，结果表明，在２５０℃～４００℃中温范围内，荼热管的传输性能优于甲基吡硌烷酮热管。

Performance tests have been carried out with respect to some large sized medium temperature heat pipes filled with two kinds of new working mediums.On the basis of an analysis of the test data compared are the start up and heat transfer characteristics of these two types of heat pipes.It has been found that in the medium temperature range of 250～400℃ there exists a marked difference in heat transfer performance between the heat pipes filled with these two different types of working mediums.
