Vorgeschlagen wird ein Axiallüfter nach der Hauptanmeldung 199 29 978.1 der Anmelderin, wobei dieser Lüfter (1) vorzugsweise auf einer Flüssigkeitsreibungskupplung (4) angeordnet ist. It proposes an axial fan after the main application 199 29 978.1 of the applicant, this fan is mounted (1), preferably on a viscous coupling (4). Im Bereich der Schaufelwurzeln, das heißt im Nabenbereich sind flossenartige Stabilisatoren (5) vorgesehen, die eine Trennung der Naben- und der Schaufelströmung bewirken. In the region of the blade root, that is, 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 is a radial blade element (6) is associated, 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 favorable influence on the fan flow will be scored in the hub area, which leads to an improvement of the fan power.
