Abstract

Die Erfindung betrifft einen Strömungsgleichrichter (1) für einen Axiallüfter (2), mit einem Grundkörper (3), der einen jeweils von zylindrischen Mantelflächen (5, 6) radial innen und außen begrenzten Kranz (4a, 4b, 4c, 4d, 4e) mit einer Mehrzahl von in Umfangsrichtung um eine Längsachse (X-X) herum verteilt und im Wesentlichen radial angeordneten, zwischen den Mantelflächen (5, 6) verlaufenden Luftleitschaufeln (7) umfasst, wobei die Luftleitschaufeln (7) in Umfangsrichtung gesehen jeweils zwischen einer anströmseitigen Schaufelkante (7a) und einer abströmseitigen Schaufelkante (7b) mit einer Krümmung (R1) zur Achsrichtung (X-X) verlaufen. Um bei hohem Volumenstrom und großer Wurfweite die Divergenz eines aus einem derartigen Strömungsgleichrichter (1) austretenden Luftstromes zu minimieren, wird vorgeschlagen, dass in dem Grundkörper (3) zwei oder mehr Kränze (4a, 4,b, 4c, 4d, 4e) mit Luftleitschaufeln (7) vorhanden sind.
