Combined fin heat exchange tube with wing-shaped flow guide structure and vortex generator

The invention discloses a combined fin heat exchange tube with a wing-shaped flow guide structure and vortex generators, which comprises an elliptical tube, a plurality of fins are fixedly connected to the two sides of the elliptical tube at equal intervals, a plurality of heat exchange mechanisms are fixedly connected to the fins at equal intervals, the heat exchange mechanisms are positioned on the two sides of the elliptical tube, and a plurality of vortex generators are fixedly connected to the leeward sides of the fins. The vortex generators are symmetrically and fixedly connected to the two sides of the oval pipe. Under the condition that the Reynolds number is within a certain range, compared with a common straight slotted fin, the integrated heat exchange capacity can be improved, and the overall efficiency of the wall-mounted gas boiler is improved. 本发明公开一种具有翼型导流结构与涡发生器的组合翅片换热管，包括椭圆管，椭圆管的两侧分别等间隔固接有若干翅片，翅片上等间隔固接有若干换热机构，换热机构位于椭圆管的两侧，翅片的背风侧固接有若干涡发生器，涡发生器对称固接在椭圆管的两侧。本发明在雷诺数在一定范围的情况下，相比于普通平直开缝翅片能够提升综合换热能力
