针对液冷式CPU(central?processing?unit)散热器散热效果差的问题,设计了液冷式CPU散热器的换热性能实验系统. 该实验系统使用基液丙二醇-水,Al2O3纳米流体和多壁碳纳米管(MWCNTs)纳米流体进行换热实验,采用单变量法对实验条件进行控制. 当加热功率为18.26 W时,基液丙二醇-水的热阻值为0.859 ℃/W,质量分数0.135%的Al2O3纳米流体的热阻值为 0.751 ℃/W,质量分数0.135%的多壁碳纳米管纳米流体的热阻值为0.739 ℃/W,质量分数0.32%的MWCNTs纳米流体的热阻值为0.457 ℃/W. 结果表明:在基液中添加纳米粒子能提高基液的换热能力,MWCNTs纳米流体的换热效果随着质量分数的增加而增强.

Aiming at the problem of poor heat dissipation in the liquid-cooled central?processing?unit(CPU) radiator, we designed the heat transfer performance experiment system in the liquid-cooled CPU radiator,by using propylene glycol-water based fluid, and nanofluids containing alumina and multi-walled carbon nanotubes (MWCNTs ) to conduct heat transfer experiment, and we optimized the experimental conditions through the single variable method. When the heating power is 18.26 W,the thermal resistance of propylene glycol-water fluid, alumina nanofluids with mass fraction of 0.135%, and MWCNTs nanofluids with mass fraction of 0.135% and 0.32% were 0.859 ℃/W, 0.751 ℃/W,0.739 ℃/W and 0.457 ℃/W, respectively. The results show that the heat transfer capability of the based fluid improves by adding nanoparticles, and the heat transfer effect of MWCNTs nanofluids enhances with the mass fraction increasing.
