Blade Of A Ventilator Wheel, Ventilator Wheel And Axial Ventilator

摘要

The invention relates in particular to a ventilator wheel of an axial ventilator, which includes multiple blades, each having radially outward extending blade forward edges and radial outer edges on the outlet side, wherein a transition from the radial outer edges to the blade forward edges is formed, in each case with a projection extending in the circumferential direction relative to the adjacent, radially outward extending blade forward edges, wherein a seamless transition is formed from the radial outer edge portion (7) to a region of the respective blade situated radially further inward.

主权项

1. A blade of a ventilator wheel, the blade comprising:
radially outward extending blade forward edges and radial outer edges on an outlet side, wherein a transition from each of the radial outer edges to a respective blade forward edge is formed with a projection extending in a circumferential direction relative to an adjacent radially outward extending blade forward edge, so that a blade edge width locally delimited in a radial outer edge portion that includes the projection is enlarged around the projection, and a seamless transition is formed from the radial outer edge portion to a region of the respective blade located radially further inward.
