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。

Abstract

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.
