    • An outlet grill (1) for use in an air-blowing device (2) having an axial fan (3) comprises grill elements (8) having main body surfaces (11) which are shaped in such a way that, in case the outlet grill (1) is indeed combined with the axial fan (3), the main body surfaces (11) extend substantially parallel to an airflow generated by the axial fan (3). The outlet grill (1) comprises tangential grill elements (8) being shaped as segments of rings, a central axis of which substantially coincides with a central grill axis (5). In an axis plane comprising the central grill axis (5), the main body surfaces (11) of a number of tangential grill elements (8) are inclined with respect to the central grill axis (5), such that the directions in which the tangential grill elements (8) extend are aligned with local directions of the airflow.
    • 一种用于具有轴流风扇(3)的送风装置(2)的出口格栅(1)包括具有主体表面(11)的格栅元件(8),该主体表面(11)的形状使得在出口 格栅(1)确实与轴流风扇(3)组合,主体表面(11)基本上平行于由轴流风扇(3)产生的气流延伸。 出口格栅(1)包括形成为环形部分的切向格栅元件(8),其中心轴线基本上与中心格栅轴线(5)重合。 在包括中心格栅轴线(5)的轴平面中,多个切向格栅元件(8)的主体表面(11)相对于中心格栅轴线(5)倾斜,使得其中 切向格栅元件(8)延伸与气流的局部方向对齐。
