Application of nanofluid in thermal performance enhancement of horizontal screen heat pipe

  • 摘要: 对纳米流体强化水平放置的丝网热管换热特性进行了实验研究.实验工质为水基CuO纳米流体,颗粒平均粒径50 nm,质量分数为0.5%~2.0%.实验在定压下进行,压力为7.45~19.97 kPa.结果显示,纳米流体替代去离子水后,热管换热性能大幅度提高.蒸发段换热系数提高了170%~410%.运行压力对热管换热特性有明显影响.压力越小,热管换热的强化越显著.热管换热特性随纳米流体质量分数的增加而提高,到达一定值后开始随之下降,最佳质量分数在1.0%左右.
