Under the guidance of sustainable development and Low Carbon Economy concept, people are harnessing new engery. At the same time, they may focus their practice in energy saving and  enhancing the utilization efficiency of energy.That is because  enhancing the utilization efficiency of energy equals energy saving. Passive augmentation heat transfer which has the advantages of simple construction and needing no additional power will become the mainstream of augmentation heat transfer methods.

By analysing the velocity fields of different cross sections, we found that satellite vortex structure was induced behind flow element by   airfoil of vortex generater with integrated wing. And with the different placements, the positions and sizes of satellite vortex were different. By comparing optical channel to the temperature decrease of heating plate with different cross sections and the related datas of velocity field, we also found that the satellite vortex effect was the primary reason for the  heat transfer characteristics  of  vortex generater with a new integrated rectangular wing.

We found that vortex generator with new integrated wing is a flow element which improves heating transfer rate without obvious resistance increase. By studing the flow field, the correlation conclusions of heating transfer and flow field are of value to the basic research of Heat Transfer Theory.

       Under the guidance of sustainable development and Low Carbon Economy concept, new engery has been exploited. Meanwhile, plentful of trial and test are devoted to saving and  enhancing utilization efficiency of energy. It was ascribed to the fact that enhancing the utilized efficiency of energy means energy saving. Passive augmentation heat transfer is popularly applied to the fields of augmentation heat transfer, owing to the advantages of the simple structure and no required additional power.
       Longitudinal vortex generater delegated a kind of effective passive augmentation heat transfer technology. The heat transfer characteristics and velocity distribution of a new integrated rectangular wing were studied in the paper. It was found that new integrated rectangular wing is a more ideal flow unit for vortex generater as compared with  rectangular wing. In addition, it is most effective placement of the generater that is placed in the lee of the wind. And the generater with 30¡ã airfoil angle of integrated rectangular wing exhibited superior heat transfer characteristics to that with 45¡ãof airfoil angle.
        Based on the analysis of the velocity fields from different cross sections, it  was found that satellite vortex structure was formed behind flow element by the induction  of   airfoil of vortex generater with integrated wings. Because of the different placements, the positions and sizes of satellite vortex were different. Though comparing optical channel, the temperature decrease of heating plate and the corresponding related data from velocity fields, it also found that the satellite vortex effect was responsible for the preferable  heat transfer characteristics  of  such novel vortex generater.
