Adopting R123 as the working medium,the effects of liquid filling ratio and heating mode on heat transfer limit were qualitatively analyzed on the open loop pulsating heat pipes test fig consisted of 40 elbows bent by fine copper tubes with inner diameter of 1 mm and 2 mm,and the experimental values were compared with calculated values by the Katpradit\'s correlations for heat transfer limit.
在由内径分别为1 mm和2 mm的细铜管弯曲而成的2组40弯头开式回路脉动热管试验装置上,采用R123为工作介质,定性分析了充液率及加热方式对传热极限的影响,并将试验值与Katpradit传热极限关联式的计算值进行了比较,结果表明:随着充液率的提高,传热极限先增大而后减小,存在一个最佳充液率(约50%);在3种加热方式中,垂直底部加热有助于脉动热管取得较大的传热极限值,而垂直顶部加热则对应较小的传热极限值。
