Description

Die Erfindung betrifft eine Kühlvorrichtung für ein Kraftfahrzeug mit einer Brennkraftmaschine.The invention relates to a cooling device for a motor vehicle with an internal combustion engine.

Kühlvorrichtungen für Kraftfahrzeuge dienen primär der Kehlung der Brennkraftmaschine, optional jedoch auch der Kühlung eines Käitemittetkreistaufes für eine Klimaanlage. Die Kühlvorrichtung umfasst daher im Allgemeinen mehrere Wärmeübertrager, z. B. einen Kühlmittelkühler, einen Ladeluftkühler, einen Ölkühler sowie einen Kondensator zur Kühlung des Kältemlttels der Klimaanlage. Der Kühlvorrichtung ist ferner ein Lüfter, vorzugsweise ein Axiallüfter mit einer Lüfterhaube zugeordnet. Bei größeren Fahrzeugen wird der Lüfter direkt von der Brennkraftmaschine über die Kurbelwelle oder einen Riementrieb angetrieben und ist somit motorfest angeordnet. Die Wärmeübertrager, insbesondere der Kühlmittelkühler dagegen sind fahrzeugfest angeordnet, ebenso die mit dem oder den Wärmeübertragern verbundene Lüfterhaube. Die dadurch entstehenden Relativbewegungen zwischen Kühler bzw. Lüfterhaube einerseits und Lüfter andererseits werden durch ein Bewegungsausgleichselement, auch kurz Ausgleichselement genannt, kompensiert, wobei das Ausgleichselement gleichzeitig eine Dichtfunktion ausübt.Cooling devices for motor vehicles primarily serve the cooling of the internal combustion engine, but optionally also the cooling of a Kitäitemittetkreistaufes for an air conditioner. The cooling device therefore generally comprises a plurality of heat exchangers, for. B. a coolant radiator, a charge air cooler, an oil cooler and a condenser for cooling the Kältemlttels the air conditioner. The cooling device is further associated with a fan, preferably an axial fan with a fan cover. For larger vehicles, the fan is driven directly by the engine via the crankshaft or a belt drive and is thus arranged fixed to the engine. By contrast, the heat exchangers, in particular the coolant coolers, are arranged fixed to the vehicle, as is the fan cover connected to the heat exchanger (s). The resulting relative movements between the radiator or fan cowling on the one hand and the fan on the other hand are compensated by a motion compensation element, also called compensating element for short, wherein the compensating element simultaneously performs a sealing function.

Eine derartige Kühlvorrichtung wurde durch die DE 33 04 297 C2 der Anmelderin bekannt. Der als Axiallüfter ausgebildete Lüfter weist einen Mantel- oder Leitring auf, welcher fest mit den Blattspitzen verbunden ist und mit dem Lüfter umläuft. Der Mantelring ragt mit seinem stromaufwärtigen, überstehenden Ende in eine Einlaufdüse, welche ebenso wie der Lüfter motorfest angeordnet ist. Zwischen einer mit einem fahrzeugfest angeordneten Kühler verbundenen Lüfterhaube und der Einlaufdüse ist ein Bewegungsausgleichselement in Form einer elastischen Lippe angeordnet, wodurch Relativbewegungen kompensiert werden.Such a cooling device was characterized by the DE 33 04 297 C2 the applicant known. The designed as an axial fan has a fan or guide ring, which is firmly connected to the blade tips and rotates with the fan. The shroud protrudes with its upstream, protruding end in an inlet nozzle, which is arranged like the fan motor fixed. Between a fan hood connected to a cooler fixed to the vehicle and the inlet nozzle, a motion compensation element in the form of an elastic lip is arranged, whereby relative movements are compensated.

Durch die DE 10 2007 031 462 A1 der Anmelderin wurde eine weitere Kühlvorrichtung für ein Kraftfahrzeug bekannt, wobei zwischen einem Kühlmittelkühler und einer Lüfterhaube ein Bewegungsausgleichselement angeordnet Ist, wodurch die Lüfterhaube eine strömungsgünstige Kontur, d. h. ohne Unterbrechungen und scharfe Umlenkungen erhält.By the DE 10 2007 031 462 A1 the applicant has disclosed a further cooling device for a motor vehicle, wherein between a coolant radiator and a fan cowl a motion compensation element is arranged, whereby the fan cowl receives a streamlined contour, ie without interruptions and sharp deflections.

Durch die DE 10 2006 047 236 A1 der Anmelderin wurde ein Axiallüfter mit einem zurückgesetzten Mantelring und vorgeschaltetem Leitring bekannt, welcher neben aerodynamischen Vorteilen den Vorteil einer geringen axialen Bautiefe aufweist, was bei heutigen Fahrzeugen infolge des eingeschränkten Einbauraumes von besonderer Bedeutung ist.By the DE 10 2006 047 236 A1 the Applicant has an axial fan with a recessed shroud and upstream guide ring is known, which in addition to aerodynamic advantages has the advantage of a small axial depth, which is of particular importance in today's vehicles due to the limited installation space.

Durch die EP 0 746 689 B1 wurde ein von einem Elektramotor angetriebener Axiallüfter, ein so genannter Elektrolüfter, bekannt, wobei der Axiallüfter einen an den Blattspitzen befestigten Mantelring aufweist und in einer Lüfterzarge bzw. einem Zargenring umlauft. Der umlaufende Lüfterrnantel bildet mit dem feststehenden Zargenring einen Ringspalt, durch welchen rezirkuliertende Luft - entgegen der Hauptströmung im Lüfter - strömt. Am Zargenring sind im Bereich des Ringspaltes in axialer Richtung verlaufende, etwa radial nach innen abragende Leitflächen angeordnet, welche einem Drall der Rezirkulationsströmung entgegen wirken sollen.By the EP 0 746 689 B1 was a powered by an electric motor axial fan, a so-called electric fan, known, the axial fan has a fixed to the blade tips shroud and circulates in a fan cowl or a Zargenring. The encircling fan shell forms with the stationary frame ring an annular gap through which recirculating air flows - counter to the main flow in the fan. On Zargenring are arranged in the region of the annular gap in the axial direction, approximately radially inwardly projecting guide surfaces, which should counteract a twist of the recirculation flow.

Die WO 98137319 Al offenbart einen Lüfter mit Lüfterring. Die EP 2 020 489 A1 offenbart einen Lüfter mit Lüfterhaube mit Spalt zwischen Lüfter und Wandung. Die US 2007/209613 A1 offenbart ebenso einen Lüfter mit Lüfterhaube mit Öffnung zum Leiten der Luftströmung.The WO 98137319 Al discloses a fan with fan ring. The EP 2 020 489 A1 discloses a fan with fan cowl with gap between fan and wall. The US 2007/209613 A1 also discloses a fan with fan cowling with opening for directing the flow of air.

Ausgehend von diesem Stand der Technik, ist es Aufgabe der Erfindung, eine Kühlvorrichtung der eingangs genannten Art dahingehend zu verbessern, dass ein strömungsgünstiger Anschluss des Leitringes an die Lüfterhaube geschaffen und eine möglichst gedrungene axiale Bauweise sowie eine hohe Luftförderleistung erreicht werden.Based on this prior art, it is an object of the invention to improve a cooling device of the type mentioned in that a streamlined connection of the guide ring to the fan cover created and a squat as possible axial design and high air flow capacity can be achieved.

Die Aufgabe der Erfindung wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The object of the invention is solved by the features of claim 1. Advantageous embodiments emerge from the subclaims.

Erfindungsgemäß ist zwischen dem Leitring und der Lüfterhaube mindestens ein Bewegungsausgleichselement vorgesehen, welches die relativ zueinander beweglichen Teile, nämlich einerseits den motorfesten Leitring und andererseits die fahrzeugfeste Lüfterhaube gegeneinander abdichtet, sodass die gesamte, den Wärmeübertrager durchsetzende Luft dem Lüfter zugeführt wird. Damit werden Leckverluste aufgrund der Relativbewegungen vermieden. Durch die Anordnung des Ausgleichselementes am stromabwärtigen Ende der Lüfterhaube kann diese strömungsgünstig, d. h. ohne Unterbrechungen ausgeführt werden - dadurch werden der Druckabfall der Luftströmung in der Lüfterhaube reduziert und die Lüfterleistung erhöht. Darüber hinaus werden die mit dem bekannten Lüfter (Mantelring und vorgeschalteter Leitring) verbundenen Vorteile, insbesondere dessen verkürzte axiale Bauweise beibehalten.According to the invention, at least one motion compensation element is provided between the guide ring and the fan cover, which seals the relatively movable parts, namely on the one hand the motor-fixed guide ring and on the other hand, the vehicle-fixed fan cover against each other, so that the entire, the heat exchanger enforcing air is supplied to the fan. This prevents leakage due to the relative movements. Due to the arrangement of the compensating element at the downstream end of the fan cowl, this can be streamlined, d. H. run without interruptions - this reduces the pressure drop of the air flow in the fan guard and increases the fan power. In addition, the benefits associated with the known fan (shroud ring and upstream guide ring), in particular its shortened axial design are maintained.

Der Leitring ist im Querschnitt etwa C-förmig ausgebildet, wobei der radial innen liegende C-Schenkel den Leitring und den mehr radial außen liegende Schenkel einen Befestigungsabschnitt bilden. An den Befestigungsabschnitt kann das Ausgleichselement auf verschiedene Art befestigt werden, z. B, durch Klemmen, durch eine Schnappverbindung oder durch ein Spannband.The guide ring is formed in cross-section approximately C-shaped, wherein the radially inner C-legs form the guide ring and the more radially outer legs a mounting portion. At the attachment portion, the compensation element can be attached in various ways, for. B, by clamping, by a snap connection or by a strap.

Der Leitring weist im Bereich eines 180°-Umlenkspaltes axial verlaufende, radial abragende Leitflächen auf, welche eine axiale Ausrichtung der drallbehafteten Rezirkulationsströmung bewirken. Damit wird der Vorteil erreicht, dass die in die Hauptströmung des Lüfters eintretende Rezirkulationsströmung weitestgehend drallfrei ist. Damit werden Strömungsverluste und Geräusche reduziert.The guide ring has, in the region of a 180 ° deflection gap, axially extending, radially projecting guide surfaces, which effect an axial alignment of the swirling recirculation flow. This achieves the advantage that the recirculation flow entering the main flow of the fan is largely free of twist. This reduces flow losses and noise.

Gemäß vorteilhaften Ausgestaltungen kann das Ausgleichselement entweder am Leitring oder an der Lüfterhaube befestigt sein - es liegt dann entweder an der Lüfterhaube oder dem Leitring dichtend an. In einem Falle ist also eine Befestigungsfunktion am Leitring und eine Dichtfunktion an der Lüfterhaube vorzusehen, während im anderen Falle eine Befestigungsfunktion an der Lüfterhaube und eine Dichtfunktion am Leitring darzustellen sind. Beide Varianten können ihre Vorteile haben.According to advantageous embodiments, the compensation element can be fastened either on the guide ring or on the fan cover - it then rests sealingly on either the fan cover or the guide ring. In one case, therefore, a fastening function on the guide ring and a sealing function on the fan guard are provided, while in the other case a fastening function on the fan guard and a sealing function on the guide ring are to be represented. Both variants can have their advantages.

Nach einer vorteilhaften Ausgestaltung weist die Lüfterhaube auf ihrer Rückwand eine ringförmige Dichtfläche auf, an welcher das Ausgleichselement anliegt und eine Dichtfunktion ausübt. Die Dichtfläche ist vorzugsweise als Planfläche ausgebildet, wodurch sich ebenfalls eine kurze axiale Bauweise ergibt.According to an advantageous embodiment, the fan cover on its rear wall on an annular sealing surface on which rests the compensating element and exerts a sealing function. The sealing surface is preferably formed as a flat surface, which also results in a short axial construction.

In weiterer vorteilhafter Ausgestaltung weist das Ausgleichselement eine ringförmige Dichtlippe auf, welche an der ringförmigen Dichtfläche mit einer elastischen Eigenspannung anliegt. Letztere ergibt sich daraus, dass die Dichtlippe beim Einbau elastisch verformt wird.In a further advantageous embodiment, the compensation element has an annular sealing lip, which bears against the annular sealing surface with an elastic residual stress. The latter results from the fact that the sealing lip is elastically deformed during installation.

In weiterer vorteilhafter Ausgestaltung ist vorgesehen, dass der Lesung einschließlich seines Befestigungsabschnittes im Wesentlichen bündig zur Lufteintrittsebene des Lüfters angeordnet ist. Damit wird der Vorteil einer kurzen axialen Bauweise erreicht, wobei das Ausgleichselement unmittelbar und ohne wesentliche Vergrößerung der axialen Bautiefe an den Leitring anschließt. Es wird damit ein strömungsgünstiger, verlustarmer Übergang von der Lüfterhaube in den Leitring bzw. in den Lüfter geschaffen.In a further advantageous embodiment, it is provided that the reading, including its attachment portion is arranged substantially flush with the air inlet level of the fan. Thus, the advantage of a short axial construction is achieved, wherein the compensation element connects directly and without significant increase in the axial depth of the guide ring. It is thus created a streamlined, low-loss transition from the fan guard in the guide ring or in the fan.

Nach einer besonders vorteilhaften Ausgestaltung ist der Leitring als Einlaufdüse ausgebildet, in welche der vordere, in Strömungsrichtung zurückgesetzte Bereich des Mantelringes hineinragt.

Fig. 1 zeigt in einem Halbschnitt eine Kühlvorrichtung 1, welche einen Kühlmittelkühler 2, eine Lüfterhaube 3 sowie einen Lüfter 4 umfasst, welcher über eine Flüssigkeitsreibungskupplung 5 von einer nicht dargestellten Brennkraftmaschine eines Kraftfahrzeuges, vorzugsweise über die Kurbelwelle angetrieben wird. Der Lüfter 4 ist daher motorfest gelagert, d. h. er führt die gleichen Bewegungen wie der Motor aus. Der Kühlmittelkühler 2 ist dagegen auf einem nicht dargestellten Fahrzeugrahmen abgestützt (fahrzeugfest gelagert) - dies trifft auch für die Lüfterhaube 3 zu, welche mit dem Kühlmittelkühler 2 fest verbunden ist. Zwischen der Lüfterhaube 3 und dem Leitring 7 treten somit Relativbewegungen auf. Der Kühlmittelkühler 2 kann durch weitere, nicht dargestellte Wärmeübertrager, z. B. Ladeluftkühler, Ölkühler oder einen Kondensator für eine Fahrzeugklimaanlage zu einem Kühlmodul ergänzt werden. Die Luftströmungsrichtung ist durch einen Pfeil L angedeutet, d. h. der Lüfter 4 ist saugend angeordnet. Die grundsätzliche Ausbildung des Lüfters 4 entspricht der Bauweise, wie sie in der eingangs genannten DE 10 2006 047 236 A1 der Anmelderin beschrieben und dargestellt ist. Danach ist der Lüfter 4 als Axiallüfter ausgebildet und weist einen umlaufenden Mantelring 6 auf, dem ein Leitring 7 zugeordnet ist. Bezüglich weiterer Einzelheiten des Lüfters 4 mit Mantelring 6 und Leitring 7 wird auf die vorgenannte Druckschrift der Anmelderin verwiesen, deren Inhalt vollumfänglich in den Offenbarungsgehalt der vorliegenden Anmeldung einbezogen wird. Fig. 1 shows in a half section, a cooling device 1, which comprises a coolant radiator 2, a fan cowl 3 and a fan 4, which is driven via a fluid friction clutch 5 by an internal combustion engine, not shown, of a motor vehicle, preferably via the crankshaft. The fan 4 is therefore mounted motor-fixed, ie it performs the same movements as the engine. By contrast, the coolant cooler 2 is supported on a vehicle frame (not shown in the vehicle) - this also applies to the fan cover 3, which is fixedly connected to the coolant radiator 2. Relative movements therefore occur between the fan cowl 3 and the guide ring 7. The coolant radiator 2 can by further, not shown heat exchanger, for. As intercooler, oil cooler or a condenser for a vehicle air conditioning system to be added to a cooling module. The air flow direction is indicated by an arrow L, ie the fan 4 is arranged sucking. The basic design of the fan 4 corresponds to the construction, as in the aforementioned DE 10 2006 047 236 A1 the applicant is described and illustrated. Thereafter, the fan 4 is formed as an axial fan and has a circumferential outer ring 6, which is associated with a guide ring 7. For further details of the fan 4 with shroud 6 and guide ring 7 reference is made to the aforementioned document of the Applicant, the contents of which is fully incorporated into the disclosure of the present application.

Zwischen dem Leitring 7 und der Lüfterhaube 3 ist erfindungsgemäß ein Bewegungsausgleichselement 8, im Folgenden kurz Ausgleichselement genannt, angeordnet, welches die Relativbewegungen zwischen Lüfterhaube 3 und Leitring 7 ausgleicht und gleichzeitig eine Abdichtung bewirkt. Der Leitring 7, welcher auf hier nicht dargestellte Weise mit der Brennkraftmaschine verbunden ist (motorfeste Anordnung), ist im Querschnitt etwa C-förmig ausgebildet und weist einen radial außerhalb des Mantelringes 6 angeordneten Befestigungsabschnitt 7a auf, in welchen ein Ende des Ausgleichselementes 8 eingeklemmt und damit gehalten ist. Das andere Ende des Ausgleichselementes 8 ist als Dichtlippe 8a ausgebildet, welche an der Lüfterhaube 3 anliegt. Letztere weist eine Luftdurchtrittsöffnung 3a auf, welche von einer kreisringförmigen Dichtfläche 3b umfasst ist, an welcher die Dichtlippe 8a anliegt und somit - bei Auftreten von Relativbewegungen - in radialer Richtung gleiten kann. Ebenso sind Relativbewegungen in Axialrichtung möglich, ohne dass die elastisch anliegende Dichtlippe 8a von der Dichtfläche 3b abhebt. Durch diese Anordnung des Ausgleichselementes 8 ergibt sich ein strömungsgünstiger Übergang von der Innenseite der Lüfterhaube 3 in den Leitring 7 und damit in den Lüfter 4. Darüber hinaus wird eine axial gedrungene Bauweise erreicht.Between the guide ring 7 and the fan cowl 3 according to the invention a motion compensation element 8, hereinafter referred to as compensation element, arranged, which compensates for the relative movements between the fan cowl 3 and guide ring 7 and at the same time causes a seal. The guide ring 7, which is connected to the internal combustion engine in a manner not shown here (motor-fixed arrangement), is approximately C-shaped in cross-section and has a radially outside of the shroud 6 arranged mounting portion 7 a, in which an end of the compensating element 8 is clamped and is held with it. The other end of the compensation element 8 is formed as a sealing lip 8 a, which rests against the fan cover 3. The latter has an air passage opening 3a, which is encompassed by an annular sealing surface 3b on which the sealing lip abuts 8a and thus - in the presence of relative movements - can slide in the radial direction. Likewise, relative movements in the axial direction are possible without the elastically fitting sealing lip 8a lifting off the sealing surface 3b. This arrangement of the compensation element 8 results in a streamlined transition from the inside of the fan cowl 3 in the guide ring 7 and thus in the fan 4. In addition, an axially compact design is achieved.

Fig. 2 zeigt eine Abwandlung des Ausgleichselementes und des Leitringes, wobei gleiche Teile mit gleichen Bezugszahlen wie in Fig. 1 bezeichnet sind. Die Lüfterhaube 3 ist hier nur teilweise, d. h. im Wesentlichen mit ihrer Dichtfläche 3b dargestellt. Ein Leitring 9 ist ebenfalls im Querschnitt C-förmig ausgebildet, weist jedoch einen sich im Wesentlichen radial erstreckenden Befestigungsabschnitt 9a auf, in welchem ein Ausgleichselement 10 eingeklemmt ist. Letzteres weist eine elastisch verformbare Dichtlippe 10a auf, welche an der Dichtfläche 3b der Lüfterhaube 3 dichtend anliegt, und zwar auch bei Auftreten von Relativbewegungen. Fig. 2 shows a modification of the compensating element and the guide ring, wherein like parts with the same reference numerals as in Fig. 1 are designated. The fan cowl 3 is here only partially, ie essentially shown with its sealing surface 3b. A guide ring 9 is also C-shaped in cross-section, but has a substantially radially extending mounting portion 9a, in which a compensation element 10 is clamped. The latter has an elastically deformable sealing lip 10a, which sealingly abuts against the sealing surface 3b of the fan cowl 3, even when relative movements occur.

Fig. 3 zeigt eine weitere Ausführungsform für einen Leitring 11 mit Ausgleichselement 12. Der Leitring 11 ist wiederum im Querschnitt C-förmig ausgebildet und weist einen äußeren zylindrischen Befestigungsabschnitt 11a auf, welcher vom Ausgleichselement 12 nach Art einer Schnappverbindung umfasst wird. Das aus einem elastischen Werkstoff, z. B. Gummi hergestelltem Ausgleichselement 12 kann somit auf den Befestigungsabschnitt 11a aufgeclipst werden und liegt dann mit der Dichtlippe 12a an der Dichtfläche 3b an. Fig . 3 shows a further embodiment of a guide ring 11 with compensating element 12. The guide ring 11 is again formed in cross-section C-shaped and has an outer cylindrical mounting portion 11a, which is covered by the compensation element 12 in the manner of a snap connection. The made of an elastic material, for. B. rubber-made compensating element 12 can thus be clipped onto the mounting portion 11 a and then rests with the sealing lip 12 a on the sealing surface 3 b.

Fig. 4 zeigt eine weitere Ausführungsform für einen Leitring 13 und ein Ausgleichselement 14. Der Leitring 13 weist einen zylindrischen Befestigungsabschnitt 13a auf, auf welchen das Ausgleichselement 14 aufgeschoben und durch ein Spannband 15 am Leitring 13 befestigt ist. Das Ausgleichselement 14 weist eine Dichtlippe 14a auf, welche an der planförmigen Dichtfläche 3b anliegt. Fig . 4 shows a further embodiment of a guide ring 13 and a compensating element 14. The guide ring 13 has a cylindrical attachment portion 13a, on which the compensation element 14 is pushed and secured by a clamping band 15 on the guide ring 13. The compensation element 14 has a sealing lip 14a, which bears against the planar sealing surface 3b.

Die oben beschriebenen Ausführungsformen der Leitringe 7, 9, 11, 13 sind jeweils durch einen C-förmig ausgebildeten Querschnitt gekennzeichnet, in welchen der stromaufwärts gelegene Teil des Mantelringes 6 hineinragt, sodass sich der aus dem eingangs genannten Stand der Technik bekannte Effekt einer Einlaufdüse ergibt. Ein Nebenluftstrom wird von außen angesaugt, um 180° umgelenkt und dem Blattspitzenbereich zugeführt. Damit ergibt sich eine weitere Stabilisierung der Lüfterströmung. Durch eine entsprechende Gestaltung und aerodynamische Verfeinerung kann der Effekt der Einlaufdüse verstärkt werden.The above-described embodiments of the guide rings 7, 9, 11, 13 are each characterized by a C-shaped cross section, in which the upstream part of the shroud 6 protrudes, resulting in the well-known from the above-mentioned prior art effect of an inlet nozzle , A secondary air flow is sucked from the outside, deflected by 180 ° and fed to the blade tip area. This results in a further stabilization of the fan flow. By appropriate design and aerodynamic refinement of the effect of the inlet nozzle can be amplified.

Fig. 5 zeigt eine Abwandlung der Erfindung für einen Lüfter 16 mit einem Mantelring 17, dem ein Leitring 18 zugeordnet ist. An den im Wesentlichen zylindrisch ausgebildeten Leitring 18 schließt sich über einen Radius r ein kreisringförmiger Dichtflansch 19 an. Am inneren Bereich der Lüfterhaube 3 ist ein elastisch ausgebildetes kreisringförmiges Ausgleichselement 20 befestigt, welches an der Außenseite des Dichtflansches 19 anliegt. Das Ausgleichselement 20 lässt Relativbewegungen in radialer und axialer Richtung zu und zeichnet sich durch eine in axialer Richtung besonders gedrungene Bauweise aus. Fig . 5 shows a modification of the invention for a fan 16 with a shroud 17, which is associated with a guide ring 18. The substantially cylindrically shaped guide ring 18 is followed by an annular sealing flange 19 via a radius r. At the inner region of the fan cowl 3, an elastically formed annular compensating element 20 is fastened, which abuts against the outside of the sealing flange 19. The compensating element 20 allows relative movements in the radial and axial direction and is characterized by a particularly compact construction in the axial direction.

Fig. 6 zeigt eine weitere Ausführungsform der Erfindung mit einem Lüfter 21, einem Mantelring 22 und einem Leitring 23, welcher sich in axialer Richtung mit dem Mantelring 22 überlappt. In axialer Verlängerung entgegen der Luftströmungsrichtung schließt sich ein Befestigungsabschnitt 23a an den Leitring 23 an, an welchem einerseits ein Ausgleichselement 24 und andererseits eine Strebe 25 befestigt sind. Mittels der Strebe 25 - sowie weiterer nicht dargestellter, über den Umfang verteilter Streben - kann der Leitring 23 gegenüber dem nicht dargestellten Motorblock befestigt Werden, sodass Lüfter 21 und Leitring 23 beide motorfest angeordnet sind. Damit kann ein minimaler Spalt zwischen Leitring 23 und Mantelring 22 realisiert werden. Dies gilt ebenso für die vorherigen Ausführungsbeispiele. Fig. 6 shows a further embodiment of the invention with a fan 21, a shroud 22 and a guide ring 23 which overlaps in the axial direction with the shroud 22. In axial extension against the direction of air flow, a mounting portion 23a connects to the guide ring 23, to which on the one hand a compensation element 24 and on the other hand a strut 25 are attached. By means of the strut 25 - and other, not shown, distributed over the circumference struts - the guide ring 23 can be attached to the engine block, not shown, so that the fan 21 and guide ring 23 are both arranged fixed to the engine. Thus, a minimal gap between the guide ring 23 and the shroud 22 can be realized. This also applies to the previous embodiments.

Fig. 7 zeigt eine weitere Befestigungsmöglichkeit der Strebe 25 an einem Leitring 26, welcher der Ausführungsform gemäß Fig. 1 entspricht, Der Leitring 26 ist C-förmig im Querschnitt und optional als Einlaufdüse ausgebildet und weist einen Befestigungsabschnitt 26a auf, an welchem die Strebe 25 angreift. Damit wird eine - insbesondere im Vergleich zu Fig. 6 - verkürzte axiale Bauweise erreicht. Fig. 7 shows a further attachment possibility of the strut 25 to a guide ring 26, which the embodiment according to Fig. 1 corresponds, the guide ring 26 is C-shaped in cross-section and optionally formed as an inlet nozzle and has a mounting portion 26 a, on which the strut 25 engages. This is one - especially in comparison to Fig. 6 - Achieved shortened axial design.

Fig. 8 zeigt eine Weiterbildung der Erfindung mit einem Lüfter 27, dem C-förmig ausgebildeten Leitring 26 und Strebe 25, welche dem Ausführungsbeispiel gemäß Fig. 7 entsprechen. In Luftströmungsrichtung hinter dem Lüfter 27 ist im radial äußeren Bereich ein Nachleitapparat 28 angeordnet, welcher an den Streben 25 befestigt bzw. mit diesen integriert ist, Ein derartiger Nachleitapparat 28 ist in der DE 10 2006 037 628 A1 der Anmelderin ausführlich beschrieben und dargestellt: es handelt sich um in Luftströmungsrichtung hinter dem Axiallüfter im Wesentlichen in radialer Richtung verlaufende Strömungsleitelemente, welche die austretende Lüfferströmung beeinflussen. Fig. 8 shows a development of the invention with a fan 27, the C-shaped guide ring 26 and strut 25, which according to the embodiment Fig. 7 correspond. In the air flow direction behind the fan 27, a Nachleitapparat 28 is disposed in the radially outer region, which is attached to the struts 25 and integrated with these, Such a Nachleitapparat 28 is in the DE 10 2006 037 628 A1 the Applicant described in detail and shown: it is in the air flow direction behind the axial fan substantially in the radial direction extending flow guide elements, which influence the exiting Lüfferströmung.

Fig. 8a zeigt einen Schnitt in der Ebene Villa-Vllla durch ein Strömungsleitelement 28a des Nachleitapparates 28, Die Drehrichtung des Lüfters 27 ist durch einen Pfeil U angedeutet. Fig. 8a shows a section in the plane Villa-Vllla by a flow guide 28a of the Nachleitapparates 28, the direction of rotation of the fan 27 is indicated by an arrow U.

Fig. 8b zeigt einen Schnitt durch das Strömungsleitelement 28a in der Ebene VIIIb-VIIIb. Die Drehrichtung des Lüfters ist durch einen Pfeil U angedeutet. Durch die Ausbildung und Anordnung der Strömungsleitelemente 28a des Nachleitapparates 28 ergibt sich eine Verzögerung der Lüfteraustrittsströmung, verbunden mit einem Druckrückgewinn. Fig. 8b shows a section through the flow guide 28a in the plane VIIIb-VIIIb. The direction of rotation of the fan is indicated by an arrow U. The design and arrangement of the flow guide elements 28a of the Nachleitapparates 28 results in a delay of the fan outlet flow, combined with a pressure recovery.

Fig. 9 zeigt eine weitere Ausführungsform eines Leitringes 30, an welchem ein Bewegungaausgleichselement 31 zur Abdichtung gegenüber einer teilweise dargestellten Lüfterhaube 32 angeordnet ist. Der Leitring 30 weist an seiner Innenseite axial verlaufende, radial nach innen abragende Leitflächen in Form von Rippen 30a auf. Fig. 9 shows a further embodiment of a guide ring 30, on which a Bewegungsaausgleichselement 31 is arranged to seal against a fan cowl 32 partially shown. The guide ring 30 has on its inside axially extending, radially inwardly projecting guide surfaces in the form of ribs 30a.

Fig. 10 zeigt einen Axiallüfter 33 mit einem Mantelring 34, welcher ein freies anströmseitiges Ringende 34a aufweist. Fig. 10 shows an axial fan 33 with a shroud 34, which has a free upstream end ring 34a.

Fig. 11 zeigt den Zusammenbau und das Zusammenwirken des Leitringes 30 gemäß Fig. 9 und des Lüfters 33 gemäß Fig. 10 in vergrößerter Darstellung. Der etwa C-förmig ausgebildete Leitring 30 bildet mit dem Ringende 34a des Mantelringes 34 einen Umfangsspalt 35 mit einer 180°-Umlenkung. Die in den Umfangsspalt 35 eintretende Strömung, eine Rezirkulationsströmung, ist durch einen Pfeil E und die aus dem Umfangsspalt 35 austretende Luftströmung ist durch einen Pfeil A gekennzeichnet. Die Hauptströmung durch den Lüfter 33 ist durch einen Pfeil S dargestellt. Die Rezirkulationsströmung wird also im Umfangsspalt 35 um 180° umgelenkt. Die eintretende Rezirkulationsströmung gemäß Pfeil E trifft auf die etwa in Axialrichtung verlaufenden und etwa radial vom Leitring 30 abragenden Leitflächen 30a, welche die mit einem Drall behaftete Strömung in axialer Richtung ausrichten, d. h. die Umfangskomponente der Rezirkulationsströmung eliminieren oder zumindest erheblich reduzieren. Damit wird erreicht, dass die aus dem Umfangsspalt 35 austretende Rezirkulationsströmung gemäß Pfeil A weitestgehend drallfrei in die Hauptströmung S eintritt, wodurch Strömungsverluste in diesem Bereich vermieden werden. Der Wirkungsgrad des Lüfters wird somit verbessert. Fig. 11 shows the assembly and the interaction of the guide ring 30 according to Fig. 9 and the fan 33 according to Fig. 10 in an enlarged view. The approximately C-shaped guide ring 30 forms with the ring end 34a of the shroud 34 has a circumferential gap 35 with a 180 ° deflection. The flow entering the circumferential gap 35, a recirculation flow, is indicated by an arrow E and the air flow emerging from the circumferential gap 35 is indicated by an arrow A. The main flow through the fan 33 is shown by an arrow S. The recirculation flow is thus deflected in the circumferential gap 35 by 180 °. The incoming recirculation flow according to arrow E applies to the approximately axially extending and approximately radially projecting from the guide ring 30 guide surfaces 30 a, which align the tapped flow in the axial direction, ie eliminate the circumferential component of the recirculation flow or at least reduce significantly. It is thus achieved that the recirculation flow exiting from the circumferential gap 35 enters the main flow S as far as possible without swirling as indicated by arrow A, whereby flow losses in this area are avoided. The efficiency of the fan is thus improved.

Fig. 12 zeigt eine Ansicht in axialer Richtung gemäß den Pfeilen XII-XII in Fig. 9. Man erkennt die vom äußeren Teil des Leitringes 30a in radialer Richtung nach innen abragenden Leitflächen 30a, welche die Rezirkulationsströmung axial ausrichten. Fig. 12 shows a view in the axial direction according to the arrows XII-XII in Fig. 9 , It can be seen from the outer part of the guide ring 30a in the radial direction inwardly projecting guide surfaces 30a, which align the recirculation flow axially.

Fig. 13 zeigt einen abgeänderten Lüfter 36 mit einem Mantelring 37, welcher ein freies, anströmseitiges Ringende 37a aufweist, welches über die Anströmkante 36a der Lüfterschaufeln vorsteht. Auch dieser Lüfter 36 kann mit dem Leitring 30 und den Leitflächen 30a kombiniert werden. In diesem Falle ergibt sich ein geringerer Umfangsspalt als im Ausführungsbeispiel gemäß Fig. 10 bzw. Fig. 11. Dafür weist der Lüfter 33 in Verbindung mit dem etwa bündig abschließenden Leitring 30 eine geringere axiale Tiefe auf und ist insofern bauratimoptimiert. Fig. 13 shows a modified fan 36 with a shroud 37, which has a free, inflow-side ring end 37a, which projects beyond the leading edge 36a of the fan blades. This fan 36 can also be combined with the guide ring 30 and the guide surfaces 30a. In this case results in a smaller circumferential gap than in the embodiment according to Fig. 10 respectively. Fig. 11 , For this purpose, the fan 33, in conjunction with the guide ring 30 which terminates approximately flush, has a smaller axial depth and is thus optimized for bauratim.
