The invention provides a grille blade for a vehicle. The cross section of the grille blade is of a wing-shaped structure, the wing-shaped structure comprises a front edge, a rear edge, a first moldedline, a second molded line and a chord length, the front end of the first molded line and the front end of the second molded line are connected with the front edge, the rear end of the first molded line and the rear end of the second molded line are connected with the rear edge, and the chord length is the distance from the front edge to the rear edge. A first sectional point is arranged on the first molded line, a second sectional point is arranged on the second molded line, a first connecting line of the first sectional point and the second sectional point equals the maximum thickness of thegrille blade, and the first connecting line is 0.07-0.11 time of the chord length; on the basis, the invention further provides an air inlet grille and a vehicle. The cross section of the grille blade provided by the invention has a wing-shaped structure, so that the grille blade better conforms to aerodynamics, has good shunting and flow guiding effects, and can effectively avoid vortex dissipation; and the heat dissipation effect on an engine room is improved, and the heat management performance of the whole engine room is greatly improved.

    本发明提供一种用于车辆的格栅叶片,格栅叶片的横截面为翼型结构,所述翼型结构包括前缘、后缘、第一型线、第二型线和弦长,第一型线和第二型线的前端均与前缘相连接,第一型线和第二型线的后端均与后缘相连接,弦长为前缘到后缘的距离;第一型线上设有第一分段点,第二型线上设有第二分段点,第一分段点与第二分段点的第一连线为格栅叶片的最大厚度,第一连线为弦长的0.07‑0.11倍;在此基础上,本发明还提供一种进气格栅和车辆;本发明提供的格栅叶片其截面具有翼型结构,更加符合空气动力学,具有良好的分流与导流作用,能够有效避免涡流耗散;提高对机舱的散热效果,极大地提升了整车机舱的热管理性能。
