Abstract (en)
[origin: WO2019196992A1] The invention relates to a fan (axial, radial or diagonal fan) comprising an impeller and an intake guide device in the flow path before the impeller, preferably before the inlet region of an inlet nozzle, the intake guide device as inflow grille (1) being designed with flat webs (5), which webs (5) form a plurality of lattice-like flow channels (6), the webs (5) extending quite predominantly between preferably two junctions (15) or between a respective junction (15) and an edge region (14, 31), and preferably predominantly three webs (5) per junction (15) meet. Alternatively the flow channels (6) of the inflow grille (1) have a honeycomb-like cross-section and/or the inflow grille (1) forms a basket-like contour in relation to the outer and/or inner enveloping surface. The invention also relates to a corresponding inflow grille.
