摘要
对浅层地温条件下以甲醇为工质的重力热管,在不同工作温度、不同充液率下的传热特性进行了初步实验研究;给出了实验用重力热管传热量、壁面温度分布和启动时间随工作温度、充液率的变化规律,为重力热管的实际工程应用提供一定参考.
In this paper,the heat transfer characteristics of gravity heat pipe with methanol as working medium in shallow ground temperature at different operating temperatures and liquid filling rates are studied. The variations of heat transfer capacity,wall temperature distribution and start-up time with operating temperature and liquid filling rate of gravity heat pipe are shown,these will provide some references for the practical application of gravity heat pipes.
