油基-碳纳米管纳米流体的冷却特性

Cooling characteristics of oil-based carbon nanotube nanofluids

采用湿法球磨工艺分散碳纳米管(CNT),制备了3种不含表面活化剂的不同碳纳米管含量的油基-CNT纳米流体淬火液。使用X-Y函数记录仪测试了这3种纳米流体的冷却曲线。结果发现,加入CNT之后,油的冷却性能提高了,并且随着CNT含量的增加,纳米流体的冷却能力逐渐增大。

Oil-based CNT nanofluids were prepared by ball-milling treated CNTs without surfactant. The cooling curves of the carbon nanotube （CNT） nanofluids were measured by using X-Y recorder. The results show that cooling characteristic of the oil increases by addition of CNT and the cooling capacity of nanofluids increases with the increase of CNT content.
