摘　　要：通过实验研究石墨烯（GNP）纳米流体振荡热管的传热性能,质量分数分别为0.01%、0.05%、0.08%和0.10%,充液率为45%～90%,加热功率为10～100 W。结果表明,充液率为45%时,GNP纳米流体可以缓解烧干;充液率为55%～70%,质量分数为0.01%具有较为明显的传热优势,其热阻最高可降低83.33%。GNP纳米流体改善PHP传热性能的原因主要是其热导率较高,表面润湿性能较好。Experiments of pulsating heat pipe（PHP） were conducted with graphene nanoplate（GNP） nanofliuds at different mass fractions（0.01%, 0.05% %, 0.08% and 0.10%） under various filling ratios（45%—90%） and heat inputs（10—100 W）. The results indicated that when the filling ratio was 45%, GNP nanofluids can significantly improve the dry state in PHP. The filling ratio ranged from 55%—70% and PHP with GNP nanofluids at the mass fraction of 0.01% showed better heat transfer performance and the maximum reduction on thermal resistance of PHP with nanofluids was 83.33% compared to that with deionized water. The main reasons for improving the heat transfer performance of PHP were higher thermal conductivity and better surface wettability of GNP nanofluids.
