Description

Die Erfindung betrifft einen Lüfter gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a fan according to the preamble of claim 1.

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 of 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.In order to improve the cooling, in fans according to the state of the art, ribs are provided on the inside of the cylinder, which serve both for the strength of the fan and for the cooling of the electric motor.

In DE 60 2004 012 549 T2 ist eine Kühllüfteranordnung für eine Brennkraftmaschine beschrieben, bei welcher ein Ventilator eine Nabe mit einem inneren und einem äußeren Nabenabschnitt enthält, wobei der innere Nabenabschnitt eine im Wesentlichen ebene Stirn definiert und mit einer Antriebswelle gekoppelt ist. Der äußere Nabenabschnitt erstreckt sich sowohl radial als auch axial in Bezug auf eine Mittelachse des Ventilators. Der Ventilator enthält darüber hinaus mehrere Blätter, die sich von einem axial verlaufenden Abschnitt des äußeren Nabenabschnitts radial erstrecken. Darüber hinaus enthält der Ventilator mehrere Rippen, die an einer inneren Oberfläche des inneren Nabenabschnitts und an einer inneren Oberfläche des äußeren Nabenabschnitts vorgesehen sind.In DE 60 2004 012 549 T2 a cooling fan assembly for an internal combustion engine is described in which a fan includes a hub with an inner and an outer hub portion, wherein the inner hub portion defines a substantially flat end and is coupled to a drive shaft. The outer hub portion extends both radially and axially with respect to a center axis of the fan. The ventilator Also includes a plurality of blades extending radially from an axially extending portion of the outer hub portion. In addition, the fan includes a plurality of ribs provided on an inner surface of the inner boss portion and on an inner surface of the outer boss portion.

In DE 100 44 066 A1 ist ein elektrischer Lüfter beschrieben, bei dem ein Kühlkörper mit Kühlrippen vorgesehen ist, welche innerhalb einer in einen Gehäusemantel des Lüfter eingeformten Lufteintrittsöffnung angeordnet sind, so dass sie von einem Kühlluftstrom durchströmt werden.In DE 100 44 066 A1 an electric fan is described, in which a cooling body is provided with cooling fins, which are arranged within a molded into a housing shell of the fan air inlet opening, so that they are flowed through by a cooling air flow.

In DE 31 27 518 A1 ist ein Axialventilator mit einem Elektromotor beschreiben, auf dessen Motorwelle eine topfförmige Nabe eines Flügelrads koaxial befestigt ist, in deren Nabenmantel axiale Lüftungsschlitze vorhanden sind, die sich von der Stirnscheibe der Nabe oder von der Nähe dieser Stirnscheibe aus zwischen den Basen der Flügelblätter nach innen erstrecken. Zusätzlich sind zur Verbesserung der Kühlung in dem rückwärtigen Stirnende des Nabenmantels axiale Einbuchtungen vorgesehen.In DE 31 27 518 A1 is an axial fan to describe an electric motor, on the motor shaft, a cup-shaped hub of an impeller is coaxially mounted in the hub shell axial vents are present, extending from the end disk of the hub or from the vicinity of this end disk between the bases of the blades inside , In addition, axial recesses are provided to improve the cooling in the rear end face of the hub shell.

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.However, the prior art configurations for improving the cooling of an electric motor housed in a fan hub using cooling fins are disadvantageous in that air is vortexed within the hub by the cooling fins, whereby 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 claim 1. Advantageous developments of the present invention are defined in the subclaims.

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 entspricht. 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. Due to 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. The configuration according to the invention thus improves the cooling of the electric motor without the disadvantages known in the prior art. Leakage air flows are avoided in this way, and effective cooling performance can be ensured in a structurally simple and thus cost-effective manner. The configuration according to the invention also has the advantage that the hub can thereby be made smaller.

Gemäß einer bevorzugten Ausführungsform ist jede von der Vielzahl von Aussparungen jeweils zwischen zwei Lüfterblättern angeordnet.According to a preferred embodiment, each of the plurality of recesses is arranged in each case between two fan blades.

Gemäß noch einer bevorzugten Ausführungsform ist jede von der Vielzahl von Aussparungen in Form eines Schlitzes ausgebildet, welcher sich im Wesentlichen von einem ersten Abschnitt der Nabenmantelfläche, welcher an die Nabenstirnfläche angrenzt, zu einem an einem offenen Ende der Nabe endenden zweiten Abschnitt der Nabenmantelfläche erstreckt.In yet another preferred embodiment, each of the plurality of recesses is in the form of a slot extending substantially from a first portion of the hub shell surface adjacent to the hub face to a second portion of the hub shell surface terminating at an open end of the hub.

Gemäß einer weiteren bevorzugten Ausführungsform erstreckt sich jede von der Vielzahl von Aussparungen im Wesentlichen senkrecht zu der Nabenstirnfläche.According to another preferred embodiment, each of the plurality of recesses extends substantially perpendicular to the hub face.

Vorzugsweise weist jedes schaufelartige Element einen vorderen Rand und einen hinteren Rand auf.Preferably, each blade-like element has a front edge and a rear edge.

Gemäß noch einer weiteren bevorzugten Ausführungsform bildet jede Aussparung jeweils den vorderen Rand eines schaufelartigen Elements und den hinteren Rand eines angrenzenden schaufelartigen Elements.According to yet another preferred embodiment, each recess forms each of the leading edge of a blade-like member and the trailing edge of an adjacent blade-like member.

Besonders bevorzugt ist es, wenn der vordere Rand des schaufelartigen Elements und der hintere Rand des angrenzenden schaufelartigen Elements in einer radialen Richtung des Lüfters voneinander beabstandet sind. Hierdurch wird die Nabe des Lüfters in vorteilhafter Weise in ihrer Form wie die Saugseite eines Radiallüfters gestaltet, was die bereits beschriebene gerichtete Kühlluftströmung verursacht.It is particularly preferable that the front edge of the blade-like member and the rear edge of the adjacent blade-like member are spaced from each other in a radial direction of the fan. As a result, the hub of the fan is advantageously designed in its shape as the suction side of a radial fan, which causes the directional cooling air flow already described.

Vorzugsweise ist der Lüfter ein Axiallüfter.Preferably, the fan is an axial fan.

Es ist darüber hinaus bevorzugt, wenn die Nabe auf der Druckseite des Lüfters eine im Wesentlichen topfförmige Aufnahme bildet, in welcher der Elektromotor angeordnet ist.It is also preferred if the hub on the pressure side of the fan forms a substantially cup-shaped receptacle, in which the electric motor is arranged.

Vorzugsweise weist jedes von der Vielzahl von schaufelförmigen Elementen eine Innenseite und eine Außenseite auf.Preferably, each of the plurality of paddle-shaped members has an inner side and an outer side.

Auch ist es vorteilhaft, wenn an der Innenseite zumindest eine Kühlrippe angeordnet ist. Die neue Luftströmung kann durch Vorsehen von Kühlrippen und einer entsprechenden Gestaltung der Kühlrippen innerhalb der Nabe auf effektive Art und Weise unterstützt und somit die Kühlwirkung weiter verbessert werden.It is also advantageous if at least one cooling rib is arranged on the inside. The new air flow can be achieved by providing cooling fins and a corresponding design of the cooling fins within the hub supports effective way and thus the cooling effect can be further improved.

Gemäß noch einer weiteren bevorzugten Ausführungsform weist die Nabenstirnfläche eine saugseitige Vorderseite und eine der Vorderseite gegenüberliegende druckseitige Rückseite auf.According to yet another preferred embodiment, the hub face has a suction-side front side and a pressure-side rear side opposite the front side.

Vorzugsweise erstrecken sich die Kühlrippen von der Innenseite des schaufelförmigen Elements zu der Rückseite der Nabenstirnfläche.Preferably, the cooling fins extend from the inside of the paddle-shaped element to the rear side of the hub end face.

Weiterhin ist es bevorzugt, wenn auf der Nabenstirnfläche zumindest eine Öffnung, insbesondere eine Vielzahl von Öffnungen vorgesehen ist. Durch die zusätzlichen Öffnungen kann Luft in Richtung der Luftströmung des Lüfters gefördert werden. Leckage-Luftströme werden effektiv vermieden.Furthermore, it is preferred if at least one opening, in particular a plurality of openings, is provided on the hub end face. Through the additional openings, air can be conveyed in the direction of the air flow of the fan. Leakage airflows are effectively avoided.

Vorzugsweise ist darüber hinaus die zumindest eine Kühlrippe im Wesentlichen L-förmig ausgebildet.Preferably, moreover, the at least one cooling fin is substantially L-shaped.

Fig. 1 zeigt eine perspektivische Ansicht eines Lüfters 1 gemäß einer Ausführungsform von vorne bzw. von der Saugseite des Lüfters 1 betrachtet wie er für eine Brennkraftmaschine eines Kraftfahrzeugs zur Kühlung eingesetzt wird. Der Lüfter 1 ist als elektrischer Axiallüfter ausgebildet, welcher ein Lüfterrad 2 mit fünf Lüfterblättern 3 aufweist, welche auf einer Nabe 4 zwischen einem äußeren Ring 5 und einer Nabenmantelfläche 6 angeordnet sind. Die Nabenmantelfläche 6 grenzt mit einem ersten Abschnitt 7 an eine Nabenstirnfläche 8 an. In der Nabenmantelfläche 6 sind um den Umfang der Nabe 4 herum gleichmäßig beabstandet Aussparungen 9 vorgesehen, welche sich schlitzartig von dem ersten Abschnitt 7 bis zu einem an einem offenen Ende der Nabe 4 endenden zweiten Abschnitt 10 der Nabenmantelfläche 6 erstrecken. Durch die Aussparungen 9 wird die Nabenmantelfläche 6 der Nabe 4 in eine Vielzahl von schaufelartigen Elementen 12 unterteilt, wodurch die Nabe 4 in Ihrer Form wie die Saugseite eines Radiallüfters ausgestaltet ist. Jedes schaufelartige Element 12 weist einen vorderen Rand 13 und einen hinteren Rand 14 auf. Die schlitzartigen Aussparungen 9 erstrecken sich im Wesentlichen senkrecht zu der Nabenstirnfläche 8. Um eine Öffnung 11 zum Hindurchströmen einer Luftströmung L beim Drehen des Lüfterrads 2 um eine Drehachse D herum vorzusehen, sind jeweils der vordere Rand 13 eines schaufelartigen Elements 12 und der hintere Rand 14 eines angrenzenden schaufelartigen Elements 12 in einer radialen Richtung des Lüfterrads 2 bzw. des Lüfters 1 voneinander beabstandet. Fig. 1 shows a perspective view of a fan 1 according to an embodiment from the front or viewed from the suction side of the fan 1 as it is used for an internal combustion engine of a motor vehicle for cooling. The fan 1 is designed as an axial electric fan, which has a fan 2 with five fan blades 3, which are arranged on a hub 4 between an outer ring 5 and a hub shell surface 6. The hub shell surface 6 adjoins a hub end face 8 with a first portion 7. In the hub shell surface 6 evenly spaced recesses 9 are provided around the circumference of the hub 4, which slots extend from the first portion 7 to a terminating at an open end of the hub 4 second portion 10 of the hub shell surface 6. Through the recesses 9, the hub shell surface 6 of the hub 4 is divided into a plurality of blade-like elements 12, whereby the hub 4 is configured in its shape as the suction side of a radial fan. Each blade-like element 12 has a front edge 13 and a rear edge 14. The slot-like recesses 9 extend substantially perpendicular to the hub face 8. In order to provide an opening 11 for flowing an air flow L when rotating the fan 2 about a rotation axis D, the front edge 13 of a blade-like element 12 and the rear edge 14 are respectively an adjacent blade-like member 12 in a radial direction of the fan 2 and the fan 1 from each other.

Fig. 2 zeigt eine perspektivische Ansicht des in Fig. 1 gezeigten Lüfters 1 von hinten bzw. in der Luftströmungsrichtung von der Druckseite des Lüfters 1 betrachtet. Die schaufelartigen Elemente 12 bilden eine im Wesentlichen topfförmige Aufnahme 15 für den hier schematisch dargestellten Elektromotor 16. Jedes schaufelartige Element 12 weist eine Außenseite 17 und eine der Außenseite 17 gegenüberliegende Innenseite 18 auf. An jedem schaufelartigen Element 12 ist auf der jeweiligen Außenseite 17 in der Ausführungsform ein Lüfterblatt 3 angeordnet. Durch die durch L gekennzeichneten Pfeile wird die Luftströmung durch die schaufelförmigen Elemente 12 bzw. durch die schlitzartigen Aussparungen 9 dargestellt, welche den Elektromotor 16 umströmt und somit effektiv kühlt. Fig. 2 shows a perspective view of the in Fig. 1 Fan 1 as viewed from the rear or in the air flow direction from the pressure side of the fan 1. The blade-like elements 12 form a substantially cup-shaped receptacle 15 for the electric motor shown here schematically 16. Each blade-like element 12 has an outer side 17 and an inner side 18 opposite the outer side 17. On each blade-like member 12, a fan blade 3 is disposed on the respective outer side 17 in the embodiment. By the arrows indicated by L, the air flow through the paddle-shaped elements 12 and through the slot-like recesses 9 is shown, which flows around the electric motor 16 and thus effectively cools.

Fig. 3 zeigt einen Ausschnitt des Lüfters 1 von Fig. 1 von hinten bzw. von der Druckseite des Lüfters 1 betrachtet. Wie erkennbar ist, bilden die einzelnen schaufelartigen Elemente 12 der Nabe 4 eine topfförmige Aufnahme 15, in welcher der hier nicht dargestellte Elektromotor 16 aufnehmbar ist. Zur weiteren Verbesserung der Kühlung des Elektromotors 16 sind an der Innenseite 18 eines jeden schaufelförmigen Elements 12 Kühlrippen 19 vorgesehen. Die Kühlrippen 19 sind im Wesentlichen L-förmig ausgebildet und erstrecken sich jeweilig von der Innenseite 18 der jeweiligen schaufelförmigen Elemente 12 auf eine druckseitige Rückseite 20 der Nabenstirnfläche 8. Fig. 3 shows a section of the fan 1 of Fig. 1 viewed from the rear or from the pressure side of the fan 1. As can be seen, the individual blade-like elements 12 of the hub 4 form a pot-shaped receptacle 15, in which the electric motor 16, not shown here, can be accommodated. To further improve the cooling of the electric motor 16, 12 cooling fins 19 are provided on the inside 18 of each paddle-shaped element. The cooling fins 19 are substantially L-shaped and each extend from the inner side 18 of the respective paddle-shaped elements 12 to a pressure-side rear side 20 of the hub end face 8.

Fig. 4 zeigt einen Ausschnitt eines Lüfters 1 gemäß einer weiteren Ausführungsform von hinten bzw. von der Druckseite des Lüfters 1 betrachtet. Die hier dargestellte Ausführungsform unterscheidet sich von der in Fig. 3 dargestellten Ausführungsform lediglich dadurch, dass in der Nabenstirnfläche 8 der Nabe 4 zusätzliche Öffnungen 21 vorgesehen sind, durch welche Luft in Richtung der Luftströmung L des Lüfters 1 gefördert werden kann, ohne dass Leckage-Luftströme auftreten. Fig. 4 shows a section of a fan 1 according to another embodiment, viewed from the rear or from the pressure side of the fan 1. The embodiment shown here differs from that in FIG Fig. 3 illustrated embodiment only in that in the hub end face 8 of the hub 4 additional openings 21 are provided, through which air in the direction of the air flow L of the fan 1 can be promoted without leakage air currents occur.

Fig. 5 zeigt eine perspektivische Ansicht des Lüfters 1 von Fig. 4 von vorne bzw. von der Saugseite des Lüfters 1 betrachtet. Wie erkannt werden kann, weist die Nabe 4 neben den Aussparungen 12 in der Nabenmantelfläche 6 zusätzliche Öffnungen 21 in der Nabenstirnfläche 8 auf, von welcher hier die der druckseitigen Rückseite (nicht dargestellt) gegenüberliegende saugseitige Vorderseite 22 sichtbar ist. Die Öffnungen 21 erstrecken sich dabei von der saugseitigen Vorderseite 22 bis zu der druckseitigen Rückseite 20 der Nabenstirnfläche 8. Fig. 5 shows a perspective view of the fan 1 of Fig. 4 viewed from the front or from the suction side of the fan 1. As can be seen, the hub 4 in addition to the recesses 12 in the hub shell surface 6 additional openings 21 in the hub end face 8, of which here the pressure-side rear side (not shown) opposite suction side Front 22 is visible. The openings 21 extend from the suction-side front side 22 to the pressure-side rear side 20 of the hub end face 8.

Fig. 6 zeigt eine Schnittansicht des Lüfters 1 von Fig. 5, wobei die durch L gekennzeichnete Luftströmung durch einen Pfeil schematisch dargestellt ist. Die Luft tritt dabei durch die Öffnungen 21 an der saugseitigen Vorderseite 22 der Nabenstirnfläche 8 ein und tritt an der druckseitigen Rückseite 20 der Nabenstirnfläche aus, wobei sie den Elektromotor 16 umströmt und zu der Hauptluftströmung des Lüfters 1 geleitet wird. Fig. 6 shows a sectional view of the fan 1 of Fig. 5 , wherein the air flow indicated by L is shown schematically by an arrow. The air enters through the openings 21 at the suction-side front side 22 of the hub end face 8 and exits at the pressure-side rear side 20 of the hub end face, wherein it flows around the electric motor 16 and is conducted to the main air flow of the fan 1.

Insgesamt betrachtet kann mit dem so ausgestalteten Lüfter 1 eine verbesserte und effektive Kühlung des Elektromotors erzielt werden.Overall, with the thus configured fan 1, an improved and effective cooling of the electric motor can be achieved.
