Abstract (en)
[origin: WO2014056657A2] The invention relates to a flow rectifier (1) for an axial fan (2), comprising a base body (3) which has a ring (4a, 4b, 4c, 4d, 4e) that is delimited radially inside and outside by in each case cylindrical surfaces (5, 6), said ring comprising a plurality of air guide vanes (7) which are distributed in the circumferential direction about a longitudinal axis (X-X) and are arranged in an essential radial manner and extend between the cylindrical surfaces (5, 6), wherein the air guide vanes (7), when seen in the circumferential direction, extend with a curvature (R1) relative to the axial direction (X-X) in each case between an inflow-side vane edge (7a) and an outflow-side vane edge (7b). In order to minimize the divergence of an airflow that exits such a flow rectifier (1) at a high volume stream and a high range of throw, it is proposed that two or more rings (4a, 4b, 4c, 4d, 4e) having air guide vanes (7) are provided in the base body (3).
