简要介绍了一种新型的三维内花瓣形螺旋肋管式油加热器的强化传热机理、特点、试验研究情况及在某电厂油系统中实际应用的效果。试验获得的传热及流阻关系式为设计使用单位提供了依据。图 2表

The experimental study is described in this paper for the heat transfer and pressure drop of the heating oil exchanger made of three dimensional inside petal helically finned tube. We decided its mechanism and feature of augmentation heat transfer. The experimental relationships for heat transfer and pressure drop are offered in this paper. This new heating oil exchanger has applied and achieved good results. Figs 2, tables 2 and refs 4.
