Abstract

Vorgeschlagen wird ein Axiallüfter nach der Hauptanmeldung 199 29 978.1 der Anmelderin, wobei dieser Lüfter (1) vorzugsweise auf einer Flüssigkeitsreibungskupplung (4) angeordnet ist. is proposed an axial flow fan according to the parent application 29 199 978.1 of the Applicant, said fan (1), preferably on a liquid friction clutch (4) is arranged. Im Bereich der Schaufelwurzeln, das heißt im Nabenbereich sind flossenartige Stabilisatoren (5) vorgesehen, die eine Trennung der Naben- und der Schaufelströmung bewirken. In the area of ​​the blade roots, i.e. in the hub region fin-like stabilizers (5) are provided, which effect a separation of the hub and the blade flow. Zusätzlich ist diesen Stabilisatoren jeweils ein Radialschaufelelement (6) zugeordnet, welches mit der Fläche des Stabilisators (5) zu einer gemeinsamen Fläche integriert sein kann. In addition, these stabilizers are each assigned a radial blade element (6), which may be integrated to form a common surface with the surface of the stabilizer (5). Durch diese speziellen Luftleitelemente kann eine günstige Beeinflussung der Lüfterströmung in deren Nabenbereich erzielt werden, die zu einer Verbesserung der Lüfterleistung führt. These special air guide elements a beneficial effect on the fan flow can be achieved in the hub area, which leads to an improvement of the fan power.
