Abstract
Description
"Lüfteranordnung zur Kühlung einer"Fan arrangement for cooling a
flüssigkeitsgekühlten Brennkraftmaschine" Die Erfindung bezieht sich auf eine Lüfteranordnung gemäß dem Oberbegriff des Patentanspruches. Liquid cooled internal combustion engine "The invention relates to to a fan arrangement according to the preamble of the patent claim.
Eine derartige Lüfteranordnung ist aus der DE-OS 31 50 152 bekannt. Bei dieser Lüfteranordnung sind der Hauptlüfter stromauf und der Zusatzlüfter stromab des Luft-Flüssigkeits-Kühlers angeordnet. Wegen des zwischen den beiden Lüftern liegenden Kühlers ist eine unmittelbare gegenseitige Beeinflussung der beiden Lüfter insbesondere hinsichtlich des Wirkungsgrades nicht gegeben.Such a fan arrangement is known from DE-OS 31 50 152. In this fan arrangement, the main fan is upstream and the auxiliary fan is downstream of the air-liquid cooler arranged. Because of the between the two fans lying cooler is a direct mutual influence of the two fans especially not given in terms of efficiency.
Der Erfindung liegt die Aufgabe zugrunde, eine Lüfteranordnung zu schaffen, die gegenüber der bekannten Lüfteranordnung einen erhöhten Wirkungsgrad und damit eine erhöhte Luftförderleistung und/oder eine verringerte Leistungsaufnahme aufweist.The invention is based on the object of a fan arrangement create, which compared to the known fan arrangement, an increased efficiency and thus an increased air delivery rate and / or a reduced power consumption having.
Die erfindungsgemäße Aufgabe ist durch die im kennzeichnenden Teil des Patentanspruches angegebenen Merkmale gelöst.The object of the invention is due to the in the characterizing part of the patent claim specified features solved.
Bei der erfindungsgemäßen Lüfteranordnung beeinflussen sich der Hauptlüfter und der Zusatzlüfter unmittelbar gegenseitig, insbesondere wird der im Zusatzlüfter erzeugte Vordrall der Kühlluft im Hauptlüfter genutzt, der Zusatzlüfter wirkt also wie ein Leitgitter, ohne daß ein gesondertes Leitgitter und der Einbauraum für dieses benötigt werden. Der dadurch verbesserte Wirkungsgrad erhöht die Förderleistung der Lüfter, es kann aber auch bei gleicher Förderleistung eine kleinere Lüfteranordnung gewählt werden. Mit der erfindungsgemäßen Lüfteranordnung ist außerdem eine Verringerung der Schallabstrahlung durch die Lüfter erreichbar.In the case of the fan arrangement according to the invention, the main fans influence one another and the additional fan directly to each other, in particular the one in the additional fan The pre-swirl generated by the cooling air in the main fan is used, so the additional fan works like a guide grille without a separate guide grille and the installation space for this are needed. The resulting improved efficiency increases the delivery rate the fan, but a smaller fan arrangement can also be used with the same flow rate to get voted. With the fan arrangement according to the invention there is also a reduction the sound radiation through the fan can be achieved.
Im folgenden wird die erfindungsgemäße Lüfteranordnung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert.In the following, the fan arrangement according to the invention is based on a In the drawing illustrated embodiment explained in more detail.
In Fahrtrichtung eines nicht weiter dargestellten Kraftfahrzeuges vor einer Brennkraftmaschine 1 ist ein Kühler 2 angeordnet, in dem das Kühlwasser der Brennkraftmaschine 1 von in Pfeilrichtung 3 durch den Kühler 2 durchströmender Luft gekühlt wird. Von der Brennkraftmaschine 1 wird unmittelbar ein Hauptlüfter 4 angetrieben, der die Kühlluft durch den Kühler 2 saugt. Unmittelbar stromauf des Hauptlüfters 4 und gleichachsig mit diesem ist ein elektrisch angetriebener Zusatzlüfter 5 angeordnet, der insbesondere bei niedriger Drehzahl des Hauptlüfters 4 zugeschaltet wird.In the direction of travel of a motor vehicle (not shown) A radiator 2 is arranged in front of an internal combustion engine 1, in which the cooling water of the internal combustion engine 1 flowing through the radiator 2 in the direction of arrow 3 Air is cooled. A main fan is provided directly by the internal combustion engine 1 4 driven, which sucks the cooling air through the radiator 2. Immediately upstream of the Main fan 4 and coaxially with this is an electrically driven auxiliary fan 5 arranged, which is switched on in particular at low speed of the main fan 4 will.
Hauptlüfter 4 und Zusatzlüfter 5 haben verschiedene Drehrichtung, also auch in unterschiedliche Richtung angestellte Schaufeln, so daß der vor dem Zusatzlüfter 5 erzeugte Vordrall der Kühl luft vom Hauptkühler 4 zu einer Wirkungsgradverbesserung der Lüfteränordnung genutzt werden kann. Da auch die beiden Naben 6 und 7 des Hauptlüfters 4 und des Zusatzlüfters 5 sich gegenseitig zumindest teilweise abdecken, ist auch der von ihnen erzeugte Stirnwiderstand geringer als bei einer Lüfteranordnung, bei der der Hauptlüfter 4 und der Zusatzlüfter 5 einen größeren axialen Abstand zueinander haben.Main fan 4 and additional fan 5 have different directions of rotation, So also employed in different directions Shovels like that that the pre-swirl of the cooling air generated in front of the additional fan 5 from the main cooler 4 can be used to improve the efficiency of the fan arrangement. There too the two hubs 6 and 7 of the main fan 4 and the auxiliary fan 5 mutually cover at least partially, the forehead resistance generated by them is also lower than with a fan arrangement in which the main fan 4 and the additional fan 5 have a greater axial distance from one another.
