【Abstract】 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.更多还原
