摘要
对正三角形截面角管脉动热管的流动和传热过程建立了数学模型,首次考虑了角管毛细管中液体的分布以及气液同向流动的特点,得到了热管的轴向温度分布和热阻等传热性能,计算热阻在0.02～0.08℃/W之间。温度分布的计算结果与实验数据符合较好。
The flow and heat transfer of pulsating heat pipe (PHP) of equilateral triangle angular cap- illary was modeled.The liquid distribution and one-direction flow in PHP were firstly considered.The temperature distribution and thermal resistance were obtained.The thermal resistance are between 0.02～0.08℃/W.The calculated temperatures have good agreement with those from experiment.
