摘　　要：随着世界能源消耗与日俱增,能源短缺问题已经成为当下不得不解决的难题。而换热过程往往伴随着大量的能源浪费,所以提升换热效率势在必行。扭带内插物作为常见的被动强化换热元件由于其操作简单、成本低的特点成为换热行业的宠儿。另一方面,纳米流体作为新兴换热工质,其良好的热物性能也让研究人员找到了方向,从而将扭带内插物与纳米流体结合,实现双重强化换热,大大提升了换热效率。With the world's energy consumption increasing day by day,energy shortage has become a problem that has to be solved.The heat transfer process is often accompanied by a large amount of energy waste,so it is imperative to improve the heat transfer efficiency.As a common passive enhanced heat transfer element,twisted tape interpolators are popular in the heat transfer industry because of their simple operation and low cost.On the other hand,as a new heat transfer working medium,Nano fluid has good thermal properties,which also let researchers find the direction,so that the twisted strip interpolation and Nano fluid are combined to achieve double enhanced heat transfer,greatly improving the heat transfer efficiency.
