蒸发段长度与充液量对高温钠热管启动过程的影响

通过对 7根结构参数不同、充液量不同的高温钠热管进行实验研究 ,给出各种情况下高温钠热管启动过程中温度随时间变化曲线 ,分析了蒸发段长度的变化及充液量的变化对高温钠热管启动过程的影响。实验结果表明直径为 2mm ,长 1 0 0 0mm的钠热管 ,蒸发段长度为 5 80mm且充有 78～ 90 g左右的充液量 ,其启动运行工作为最佳

Influences of the Evaporator Length and Liquid-Filled Content on the Startup Operation of the High Temperature Sodium Heat Pipes

An experimental investigation was made of the seven high temperature sodium heat pipes with different structure parameters and different liquid filled content, the temperature curve varying with time in the startup operation of the high temperature sodium pipes in various conditions was given, the influences of the changes of evaporator length and liquid filled content on the startup operation of the high temperature sodium pipes were analyzed. The experimental result shows that a high temperature sodium heat pipe with 25mm diameter, 1 000mm length, 580mm evaporator and 78～90g liquid filled content had the best startup operation.
