摘　　要：针对利用电加热板作为热源的同一回路型自激振荡流热管,在相同的工质及充液率、相同的倾角等条件下。通过改变加热板的位置,对其壁温和热传输特性随加热功率的变化进行了对比实验研究.实验结果分析表明:对于非微尺度结构的自激振荡流热管,热源位置对其起动功率及循环动力等热传输性能有很大影响.最佳的热源位置应该在自激振荡流热管的最下部,并且热源下部不应再出现绝热段.Experiments were performed on a self-exciting mode oscillating flow heat pipe （SEMOS HP） with different heating positions at the same substance and inclined angle using an electric heating plate as heat source. The heat transfer characteristics and the temperature of wall were analyzed when the heating power changed by comparing the experiments. The result showes that startup power and the revolving power are effected by the heating positions for the Micro-Scale of SEMOS HPI There have the optimal heating source position located below the heat pipe and there didn＇t have adiabatic section at the bottom of the heating source.
