Elektrolüfter werden im Stand der Technik unter anderem in Motorkühlungsgebläsen eingesetzt. Derartige Elektrolüfter mit beispielsweise einem axialen Lüfterrad weisen als Antrieb einen Elektromotor auf, welcher innerhalb einer Nabe des Lüfters angeordnet ist. Durch diese Anordnung innerhalb der Nabe sitzt der Elektromotor jedoch außerhalb des eigentlichen luftstroms und wird daher nur schlecht gekühlt.Electric fans are used in the prior art, inter alia, in engine cooling fans. Such electric fans with, for example, an axial fan wheel have as drive to an electric motor, which is arranged within a hub of the fan. By this arrangement within the hub of the electric motor, however, sits outside the actual air flow and is therefore only badly cooled.
Zur Verbesserung der kühlung sind in Lüftern gemäß dem Stand der Technik an der zylinderförmig ausgeführten Nabe an deren Innenseite Rippen vorgesehen, die sowohl der Festigkeit des Lüfters als auch der Kühlung des Elektromotors dienen.To improve the cooling ribs are provided in fans according to the prior art on the cylinder-shaped hub on the inside, which serve both the strength of the fan and the cooling of the electric motor.

Die im Stand der Technik bekannten Konfigurationen zur. Verbesserung der Kühlung eines in einer Lüfternabe aufgenommenen Elektromotors, die Kühlrippen verwenden, sind jedoch nachteilig darin, dass durch die Kühlrippen Luft innerhalb der Nabe verwirbelt wird, wodurch eine gerichtete Strömungsführung nicht sichergestellt werden kann. Andererseits führen Konfigurationen, welche zur Verbesserung der Kühlung des Elektromotors zusätzliche Luftschlitze oder Öffnungen verwenden, zu einem Leckage-Luftstrom.The known in the prior art configurations for. However, improving cooling of an electric motor accommodated in a fan hub using cooling fins is disadvantageous in that air is swirled within the hub by the cooling fins, whereby a directional flow guidance can not be ensured. On the other hand, configurations that use additional louvers or openings to improve the cooling of the electric motor result in a leakage airflow.
Daher ist es die Aufgabe der vorliegenden Erfindung, einen Lüfter vorzusehen, bei dem die Kühlung eines in einer Nabe aufgenommenen Elektromotors verbessert wird.Therefore, it is the object of the present invention to provide a fan in which the cooling of an electric motor received in a hub is improved.
Die Aufgabe der vorliegenden Erfindung wird durch einen Lüfter mit den Merkmalen gemäß Anspruch 1 gelöst. Vorteilhafte Weiterbildungen der vorliegenden Erfindung sind in den Unteransprüchen definiert.The object of the present invention is achieved by a fan having the features according to
Erfindungsgemäß wird ein Lüfter für eine Brennkraftmaschine vorgesehen, welcher ein von einem in einer Nabe angeordneten Elektromotor angetriebenes Lüfterrad aufweist, welches mit einer Vielzahl von an der Nabe angeordneten Lüfterblättern ausgebildet ist, wobei die Nabe mit einer Nabenstirnfläche und einer Nabenmantelfläche ausgebildet ist, wobei in der Nabenmantelfäche eine Vielzahl von Aussparungen vorgesehen ist, welche die Nabenmantelfläche in eine Vielzahl von schaufelartigen Elementen unterteilen. Durch die erfindungsgemäße Konfiguration weist die Nabe des Lüfters im Wesentlichen eine Anordnung auf, welche der Saugseite eines Radiallüfters ehtspricht. Hierdurch wird ein gerichteter Luftstrom erzeugt, welcher im Bereich der Saugseite der Lüfterblätter zugeführt wird, da hier ein niedriger statischer Druck herrscht, Durch die erfindungsgemäße Konfiguration wird somit die Kühlung des Elektromotors ohne die im Stand der Technik bekannten Nachteile aufzuweisen verbessert. Leckage-Luftströme werden auf diese Weise vermieden, und eine effektive Kühlleistung kann auf konstruktiv einfache und somit kostengünstige Art und Weise sichergestellt werden. Die erfindungsgemäße Konfiguration hat auch den Vorteil, dass die Nabe hierdurch kleiner ausgeführt werden kann.According to the invention, a fan for an internal combustion engine is provided, which comprises an electric motor driven in a hub fan wheel, which is formed with a plurality of arranged on the hub fan blades, wherein the hub is formed with a hub face and a hub shell surface, wherein in the Nabenmantelfäche a plurality of recesses is provided, which divide the hub shell surface into a plurality of blade-like elements. By virtue of the configuration according to the invention, the hub of the fan essentially has an arrangement which corresponds to the suction side of a radial fan. As a result, a directed air flow is generated, which is supplied in the region of the suction side of the fan blades, since there is a low static pressure, Thus, by the configuration according to the invention, the cooling of the electric motor without the disadvantages known in the prior art has improved. Leakage air flows are avoided in this way, and effective cooling performance can be ensured in a structurally simple and thus cost-effective manner.
