Adverse effect of non-condensable gas on the operating performance of loop heat pipe

  • 摘要: 通过向环路热管内充装定量氮气来模拟实际不凝气体的生成,考察了不同不凝气体含量、热载荷和热沉温度条件下,环路热管工作性能的变化.结果显示不凝气体对工作性能造成的不利影响体现在:取决于热载荷和热沉温度,可导致稳态工作温度升高2~10℃;在小于60W的热载荷区间或者-5℃的热沉温度条件下,不凝气体导致的不利影响更加显著;改变控温性能,产生一个故障热载荷区间;启动时间、启动温度、启动温升增大;引发温度波动现象和系统运行失效.基于特征点温度的变化特性,分析并讨论了不凝气体影响环路热管工作性能的物理机理.
