摘　　要：采用X-Y函数记录仪(LM20A-200型),测定了水及水基-碳纳米管(CNT)纳米流体淬火液冷却特性曲线。研究了含量的变化对水基—CNT纳米流体淬火液冷却特性曲线的影响。结果表明,纳米流体的冷却性能比水好,并且随着CNT含量的增大,纳米流体冷却速度逐渐增大。Cooling curves of water based-carbon nanotube(CNT)nanofluids quenchant and pure water were measured by using X-Y function recorder.The effect of the Carbon Nanotube(CNT)content on the cooling characteristic has been studied during immersion quenching in water based-CNT nanofluids.The results showed that the cooling performance of the nanofluids is better than that in pure water and the cooling rate of the nanofluids increased with the increasing CNT content.
