A new class of heat transfer fluids called " nanofiuids " has been proposed . nanofluids refer to a new kind of heat transport fluids by suspending nanoscaled metallic or nonmetallic particles in base fluids . nanofluids are expected to exhibit heat transfer properties superior to those of conventional heat transfer fluids 纳米材料科学的迅速发展给强化传热领域带来了新的机遇，有学者提出了一个崭新的概念?纳米流体：即以一定的方式和比例在液体中添加纳米级金属或非金属氧化物粒子，形成一类新的传热冷却工质。
