Description
Die Erfindung betrifft eine Lüfteranordnung nach der Art von Anspruch 1.The invention relates to a fan assembly according to the type of claim 1.
Bei Kraftfahrzeugen mit Verbrennungsmotor wird die vom Verbrennungsmotor produzierte Abwärme über einen Wärmetauscher – Kühler – an die Umgebungsluft abgegeben. Bei Fahrzeugen mit Frontmotor ist der Wärmetauscher in Fahrtrichtung vorne eingebaut und wird über Kühlergrillöffnungen mit Frischluft versorgt. Zusätzlich ist dem Wärmetauscher ein Ventilator nachgeordnet, der einen Luftstrom durch den Wärmetauscher erzeugt. Dies ist gerade bei niedriger Fahrtgeschwindigkeit erforderlich, da die dabei nur mit niedriger Geschwindigkeit zugeführte Frischluft nur eine entsprechend geringe Wärmeabfuhr bedingt. In motor vehicles with an internal combustion engine, the waste heat produced by the internal combustion engine is released via a heat exchanger - cooler - to the ambient air. On vehicles with a front engine, the heat exchanger is installed at the front in the direction of travel and is supplied with fresh air via grille openings. In addition, a fan is arranged downstream of the heat exchanger, which generates an air flow through the heat exchanger. This is necessary especially at low driving speed, since the fresh air supplied only at low speed only causes a correspondingly low heat dissipation.

Aufgabe der Erfindung ist es, eine Lüfteranordnung insbesondere mit Blick auf die Geräuschemission in gegenüber den bekannten Lösungen verbesserter Ausführung vorzuschlagen.The object of the invention is to propose a fan arrangement, in particular with regard to the noise emission in relation to the known solutions of improved design.
Diese Aufgabe wird durch die im Patentanspruch 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in claim 1.
Gemäß der Erfindung ist eine Lüfteranordnung für den Wärmetauscher eines Kraftfahrzeuges vorgesehen, wobei dem Wärmetauscher in Luftzufuhrrichtung ein Ventilator nachgeordnet ist, der Ventilator in einer Lüfterhaube angeordnet ist, welche im Wesentlichen die Luftdurchstömfläche des Wärmetauschers abdeckt, die Lüfterhaube in axialer Richtung, in Richtung der Luftströmung beabstandet zu dem Wärmetauscher angeordnet ist, und die Lüfterhaube über einen Dichtungsteil an den Wärmetauscher angekoppelt ist, wobei in dem Dichtungsteil sich gegenüberliegend jeweils wenigstens zwei Luftdurchgangsöffnungen angeordnet sind.According to the invention, a fan assembly for the heat exchanger of a motor vehicle is provided, wherein the fan in the air supply direction, a fan is arranged downstream, the fan is arranged in a fan cover, which covers substantially the Luftdurchstömfläche of the heat exchanger, the fan cover in the axial direction, in the direction of air flow spaced from the heat exchanger is arranged, and the fan cowl is coupled via a sealing part to the heat exchanger, wherein in the sealing part opposite at least two air passage openings are arranged.
Vorzugsweise liegen diese wenigstens zwei Luftdurchgangsöffnungen oberhalb und unterhalb des Ventilators. Bevorzugt sind die Luftdurchgangsöffnungen in Form von Schlitzen ausgebildet.Preferably, these at least two air passage openings are above and below the fan. Preferably, the air passage openings are formed in the form of slots.
Die Luftdurchgangsöffnungen haben bevorzugte vorzusehende Abmessungen. Unter der axialen Abmessung ist die Abmessung in Achsrichtung des Ventilators zu verstehen. Die Abmessung in lateraler Richtung ist entsprechend senkrecht dazu, also insbesondere eine Richtung in Umfangsrichtung des Ventilators.The air passage openings have preferred dimensions to be provided. The axial dimension is the dimension in the axial direction of the fan to understand. The dimension in the lateral direction is correspondingly perpendicular thereto, ie in particular a direction in the circumferential direction of the fan.
Eine bevorzugte Ausgestaltung der Erfindung sieht vor, dass die Schlitze in lateraler Richtung wenigstens einen Faktor 0,025 des Durchmessers des Ventilators aufweisen. Maximal erstreckt sich der Schlitz in lateraler Richtung um 1/10 des Durchmessers des Ventilators. A preferred embodiment of the invention provides that the slots in the lateral direction have at least a factor of 0.025 of the diameter of the fan. At most, the slot extends in the lateral direction by 1/10 of the diameter of the fan.
Die Abmessung der Schlitze in axialer Richtung beträgt wenigstens 0,0025 des Durchmessers des Ventilators, wobei die maximale Erstreckung in Achsrichtung durch Abmessung des Übergangsbereiches in Achsrichtung plus der Länge des Ventilators in Achsrichtung beträgt. The dimension of the slots in the axial direction is at least 0.0025 of the diameter of the fan, wherein the maximum extent in the axial direction by dimensioning the transition region in the axial direction plus the length of the fan in the axial direction.
Die erfindungsgemäß vorgesehenen Luftdurchgangsöffnungen können eine beliebige Form aufweisen, so dass sich eine gute Anpassbarkeit an die Gestaltung der Lüfterhaube ergibt. Bevorzugt weist eine Luftdurchgangsöffnung wenigstens einen Flächenanteil von 0,0000625 der Luftdurchgangsfläche des Ventilators auf. The inventively provided air passage openings may have any shape, so that there is a good adaptability to the design of the fan guard. An air passage opening preferably has at least an area fraction of 0.0000625 of the air passage area of the fan.
Des Weiteren erfolgt die Erläuterung eines Ausführungsbeispiels der Erfindung an Hand der Zeichnungen.Furthermore, the explanation of an embodiment of the invention with reference to the drawings.
In der Ausführung nach
Zwei Luftdurchgangsöffnungen LD sind unterhalb des Ventilators im Dichtungsteil DT angeordnet. Diese Luftdurchgangsöffnungen sind somit in dem unteren Teil des Dichtungsteiles DT angeordnet. Zwei weitere Luftdurchgangsöffnungen LD (nicht dargestellt) befinden sich oberhalb des Ventilators V, also im oberen Bereich des Dichtungsteils DT. Die Luftdurchgangsöffnungen LD, die beiden beschriebenen Paare, sind im Dichtungsteil DT somit gegenüberliegend angeordnet. Die Orientierung oben bzw. unten sei hier in Bezug auf die Luftzufuhr- und die Fahrtrichtung des nicht dargestellten Fahrzeuges verstanden.Two air passage openings LD are arranged below the fan in the seal part DT. These air passage openings are thus arranged in the lower part of the sealing part DT. Two further air passage openings LD (not shown) are located above the fan V, ie in the upper region of the sealing part DT. The air passage openings LD, the two described pairs, are thus arranged opposite each other in the sealing part DT. The orientation above or below is understood here in relation to the Luftzufuhr- and the direction of travel of the vehicle, not shown.
