摘　　要：对工质为Cu-水纳米流体的自激振荡流热管在不同激光加热功率下的热传输特性进行了实验研究,并对工质为蒸馏水的自激振荡流热管的传热性能进行了比较。通过对不同的充液率、Cu纳米颗粒份额的Cu-水纳米流体自激振荡流热管实验结果分析发现:自激振荡流热管内Cu-水纳米流体的热传输具有一定的特殊性,在一定条件下纳米流体可以起到强化传热的作用,但决定纳米流体自激振荡流热管热传输性能的参数应是充液率。The heat transfer characteristics of self-exciting mode oscillating-flow heat pipes （SEMOS）, using Cu-water nanofluid as working medium, have been studied under various laser initiated heat input and compared with those of similar pipes but using mere distilled water as working medium. Tests were performed with various filling rates and various percentages of Cu nanoscale particles. By analyzing test results, it was found that Cu-water nanofluids in SEMOS heat pipes have their own heat transfer particularities. Though, under certain conditions, nanofluids themselves can enhance heat transfer, but the filling rate should be the parameter that determines the heat transfer performance of nanofluid filled SEMOS heat pipes.
