Experimental study on tube apertures expanded on single segmental baffle 单弓形折流板管孔扩孔试验研究
The heat exchanger structure often using traditional segmental baffle form, this structure easy to form dead-heat, causing the heat transfer area and heat transfer tube outer wall did not make full use of severe scaling, resulting in greatly reduced heat transfer performance. 该换热器结构形式通常采用传统的弓形折流板形式,这种结构容易形成换热死区,从而造成传热面积未充分利用及换热管外壁严重结垢,致使换热性能大大降低。
Through the study on the effects of structure parameters of heat exchanger shell on the characteristics of flow field, it could be figured out that the dead zone could be decreased by reducing the board space in segmental baffle board heat exchangers. 研究了换热器壳程的结构参数对于流场特性的影响,得出减小折流板的间距可以使弓形折流板换热器内的流动死区减小,为换热器的优化设计提供了理论依据。
