摘要(Abstract)：

对圆管式及方槽板式脉动热管试验进行了结构及运行特性的比较。分析表明,与圆管式脉动热管相比,方槽板式脉动热管存在尖角的毛细吸附力以及相邻槽道通过薄壁的横向热平衡。这些结构因素影响脉动热管的运行特性。试验表明,在水平及垂直顶部加热模式下,两种热管的最佳充液率范围相同,均为40%~70%;在垂直底部加热模式下,圆管式脉动热管的最佳充液率范围是30%~70%,而方槽板式脉动热管的最佳充液率则为15%。
The structural and operational characteristics between two kinds of pulsating heat pipes(PHPs) were compared.It is revealed that the flat plate type PHPs with square channels has two structural characteristics distinct different from the circle tube type PHPs,such as the sharp angled edges and the transverse heat balance effects through the thin wall between two neighboring channels,which contributed to the distinct operational characteristics.Experiments show that in the horizontal and vertical top heat modes,both type PHPs have the same optimum filling ratio ranging from 40% to 70%;in the vertical bottom heat mode,the circle tube type PHPs has an optimum filling ratio ranging from 30% to 70%,while the flat plate type PHPs with square channels has an optimum filling ratio of about 15%.
