| 摘 要： | 本文建立了环路型振荡流热管物理数学模型。数值计算结果表明,汽泡的交替膨胀和压缩使管内工质维持振荡运动,热管冷却端的散热情况是影响振荡流热管内部振荡运动的重要因素。热管内部振荡运动受倾角、充液率和加热功率影响,其变化趋势与前期实验结果基本一致。热管内脉动运动愈剧烈,热管的传热性能愈好。

| Abstract: | In this paper,theoretical models were developed for a close loop oscillating heat pipe. The numerical results showed that the alternating expansion and compression of vapors caused a self-sustained oscillating flow inside the heat pipe,which was affected by the heat dissipation at the cooling section.The oscillating action also affected by the inclination angle,filling ratio and heating power,the severer the oscillatory action,the better the heat transfer performance. |
