Description
Kühleinrichtung für ein Kraftfahrzeug, insbesondere für einen Kraftwagen Cooling device for a motor vehicle, in particular for a motor vehicle
Die Erfindung betrifft eine Kühleinrichtung für ein Kraftfahrzeug, insbesondere für einen Kraftwagen, gemäß dem Oberbegriff vom Patentanspruch 1. The invention relates to a cooling device for a motor vehicle, in particular for a motor vehicle, according to the preamble of patent claim 1.
Eine solche Kühleinrichtung für ein Kraftfahrzeug, insbesondere für einen Kraftwagen, ist beispielsweise bereits der DE 10 2018 114 499 A1 als bekannt zu entnehmen. Die Kühleinrichtung weist wenigstens einen als Wärmetauscher ausgebildeten Kühler auf, dessen Grundebene schräg zur Fahrzeuglängsrichtung des Kraftfahrzeugs verläuft. Der Kühler umfasst Lamellen, die von einem beispielsweise flüssigen Kühlmittel durchströmbar und, insbesondere bei einer Vorwärtsfahrt des Kraftfahrzeugs, von Luft aus einer Umgebung des Kraftfahrzeugs umströmbar sind. Die Lamellen folgen in Fahrzeughochrichtung des Kraftfahrzeugs aufeinander. Des Weiteren offenbart die US 2004/0031597 A1 einen Wärmetauscher. Such a cooling device for a motor vehicle, in particular for a motor vehicle, is already known, for example, from DE 10 2018 114 499 A1. The cooling device has at least one cooler designed as a heat exchanger, the base plane of which runs at an angle to the longitudinal direction of the motor vehicle. The cooler comprises fins through which a coolant, for example a liquid coolant, can flow and, in particular when the motor vehicle is traveling forwards, around which air from the surroundings of the motor vehicle can flow. The slats follow one another in the vehicle vertical direction of the motor vehicle. Furthermore, US 2004/0031597 A1 discloses a heat exchanger.
Aufgabe der vorliegenden Erfindung ist es, eine Kühleinrichtung der eingangs genannten Art zu verbessern. The object of the present invention is to improve a cooling device of the type mentioned at the outset.
Diese Aufgabe wird durch eine Kühleinrichtung mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen Weiterbildungen der Erfindung sind in den übrigen Ansprüchen angegeben. This problem is solved by a cooling device with the features of patent claim 1 . Advantageous configurations with expedient developments of the invention are specified in the remaining claims.
Um eine Kühleinrichtung der im Oberbegriff des Patentanspruchs 1 angegebenen Art zu verbessern, ist es erfindungsgemäß vorgesehen, dass die vorzugsweise eigensteifen und somit formstabilen Lamellen des schräg verlaufenden oder schräg stehenden Kühlers jeweils in Fahrzeuglängsrichtung betrachtet parallel zur Fahrzeuglängsrichtung und dadurch schräg zur Grundebene des Kühlers verlaufen. Mit anderen Worten weist die jeweilige Lamelle eine in Fahrzeuglängsrichtung von vorne nach hinten oder umgekehrt verlaufende Erstreckung auf, die, im Gegensatz zu dem Kühler beziehungsweise zu der Grundebene, nicht ebenfalls schräg gestellt, das nicht ebenfalls
schräg zur Fahrzeuglängsrichtung verläuft, sondern die Erstreckung verläuft zumindest im Wesentlichen parallel zur Fahrzeuglängsrichtung und somit senkrecht zur Fahrzeughochrichtung des Kraftfahrzeugs. Dadurch kann beispielsweise eine übermäßige Umlenkung der die Lamellen umströmenden Luft vermieden werden, sodass sich im Vergleich zu herkömmlichen Lösungen eine verbesserte an- und/oder Umströmung der Lamellen des an sich beziehungsweise insgesamt betrachtet schräg gestellten Kühlers realisieren lässt. Dadurch kann eine besonders hohe Kühlungsleistung des Kühlers realisiert werden, und im Vergleich zu herkömmlichen Lösungen kann Bauraum gespart werden. In order to improve a cooling device of the type specified in the preamble of claim 1, it is provided according to the invention that the preferably inherently rigid and thus dimensionally stable lamellae of the sloping or sloping radiator, viewed in the longitudinal direction of the vehicle, run parallel to the longitudinal direction of the vehicle and thus at an angle to the base plane of the radiator. In other words, the respective slat has an extension running in the longitudinal direction of the vehicle from front to rear or vice versa, which, in contrast to the radiator or to the base plane, is not also inclined runs obliquely to the vehicle longitudinal direction, but the extension runs at least substantially parallel to the vehicle longitudinal direction and thus perpendicular to the vehicle vertical direction of the motor vehicle. As a result, excessive deflection of the air flowing around the fins can be avoided, for example, so that compared to conventional solutions, an improved flow onto and/or around the fins of the cooler, which is inclined per se or viewed overall, can be implemented. As a result, a particularly high cooling capacity of the cooler can be achieved, and installation space can be saved in comparison to conventional solutions.
Der Erfindung liegen dabei insbesondere die Erkenntnisse zugrunde, dass beispielsweise als Kühlmodule ausgebildete oder auch als Kühlmodule bezeichnete Kühler von modernen Kraftfahrzeugen wie beispielsweise Kraftwagen, insbesondere Personenkraftwagen, schräg im jeweiligen Kraftfahrzeug angeordnet werden. Hierunter ist zu verstehen, dass die jeweilige Grundebene des jeweiligen Kühlers nicht etwa senkrecht zur Fahrzeuglängsrichtung verläuft, sondern um die auch als y-Richtung oder y-Achse bezeichnete Fahrzeugquerrichtung gedreht ist, derart, dass die Grundebene beispielsweise parallel zur Fahrzeugquerrichtung und schräg zur Fahrzeuglängsrichtung verläuft. Dabei verlaufen üblicherweise auch die Lamellen beziehungsweise deren in Fahrzeuglängsrichtung hin nach vorne beziehungsweise umgekehrt verlaufende Erstreckung schräg zur Fahrzeuglängsrichtung. In der Folge muss für eine senkrechte Anströmung des Kühlers, das heißt für eine senkrecht zur Grundebene verlaufende Anströmung der Lamellen die anströmende Luft insbesondere entlang der auch als x- Achse oder x-Richtung bezeichneten Fahrzeuglängsrichtung umgelenkt werden. Damit einher gehen negative Auswirkungen hinsichtlich Bauraum, das heißt Bauraumbedarf sowie gegebenenfalls hinsichtlich der Kühlleistung des Kühlers. Die zuvor genannten Probleme und Nachteile können durch die Erfindung vermieden werden. The invention is based in particular on the findings that, for example, coolers designed as cooling modules or also referred to as cooling modules of modern motor vehicles such as motor vehicles, in particular passenger cars, are arranged at an angle in the respective motor vehicle. This means that the respective base plane of the respective radiator does not run perpendicular to the longitudinal direction of the vehicle, but is rotated about the vehicle transverse direction, also known as the y-direction or y-axis, such that the base plane runs parallel to the vehicle transverse direction and obliquely to the vehicle longitudinal direction, for example . In this case, the slats or their extension running forwards or vice versa in the longitudinal direction of the vehicle usually also run obliquely to the longitudinal direction of the vehicle. As a result, the incoming air must be deflected in particular along the longitudinal direction of the vehicle, also referred to as the x-axis or x-direction, for a vertical flow towards the radiator, ie for a flow towards the fins perpendicular to the base plane. This is accompanied by negative effects with regard to installation space, ie installation space requirements and possibly with regard to the cooling capacity of the cooler. The problems and disadvantages mentioned above can be avoided by the invention.
Beispielsweise sind, insbesondere in Fahrzeughochrichtung, zwischen den auch als Kühlmittel führende Lamellen bezeichnete Lamellen luftführende, weitere Lamellen des Kühlers angeordnet, welche vorzugsweise an in parallel zur Fahrzeuglängsrichtung verlaufenden Verlauf der kühlmittelführenden Lamellen angepasst sind. Hierdurch kann eine besonders hohe Kühlleistung realisiert werden. Des Weiteren kann durch die Erfindung ein vorteilhafter Kompromiss zwischen luftseitigem Druckverlust und Wärmeübertragung zwischen dem die Lamellen durchströmenden Kühlmittel und der die Lamellen umströmenden Luft realisiert werden, wobei insbesondere ein luftseitiger Druckverlust insbesondere bei einem Lüfterbetrieb klein gehalten werden kann. Bei
herkömmlichen, schräg gestellten Kühlern kann eine vorteilhafte Anströmung der kühlmittelführenden Lamellen durch Umlenken der die Lamellen an- und umströmenden Luft realisiert werden, wobei daraus jedoch Totwassergebiete resultieren können, welche nicht zur Wärmeübertragung beitragen. Alternativ oder zusätzlich kann ein erhöhter Bauraumbedarf bestehen. Auch diese Nachteile können durch die Erfindung vermieden werden. For example, in particular in the vertical direction of the vehicle, air-guiding additional fins of the radiator are arranged between the fins also referred to as coolant-carrying fins, which are preferably adapted to the course of the coolant-carrying fins running parallel to the longitudinal direction of the vehicle. As a result, a particularly high cooling capacity can be achieved. Furthermore, the invention can achieve an advantageous compromise between air-side pressure loss and heat transfer between the coolant flowing through the fins and the air flowing around the fins, with an air-side pressure loss being able to be kept small, particularly during fan operation. At With conventional, inclined coolers, an advantageous inflow of the coolant-carrying fins can be realized by deflecting the air flowing on and around the fins, but this can result in dead water areas that do not contribute to the heat transfer. Alternatively or additionally, there may be an increased space requirement. These disadvantages can also be avoided by the invention.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels sowie anhand der Zeichnung. Die vorstehend in der Beschreibung genannten Merkmale und Merkmalskombinationen sowie die nachfolgend in der Figurenbeschreibung genannten und/oder in der einzigen Figur alleine gezeigten Merkmale und Merkmalskombinationen sind nicht nur in der jeweils angegebenen Kombination, sondern in anderen Kombinationen oder in Alleinstellung verwendbar, ohne den Rahmen der Erfindung zu verlassen. Further advantages, features and details of the invention result from the following description of a preferred exemplary embodiment and from the drawing. The features and combinations of features mentioned above in the description and the features and combinations of features mentioned below in the description of the figures and/or shown alone in the single figure can be used not only in the combination specified, but also in other combinations or on their own, without going beyond the scope of the leave invention.
Die Zeichnung zeigt in der einzigen Fig. ausschnittsweise eine schematische Seitenansicht einer Kühleinrichtung für ein Kraftfahrzeug, insbesondere für einen Kraftwagen. In the single figure, the drawing shows a detail of a schematic side view of a cooling device for a motor vehicle, in particular for a motor vehicle.
Die einzige Fig. zeigt ausschnittsweise in einer schematischen Seitenansicht eine Kühleinrichtung 10 für ein vorzugsweise als Kraftwagen, insbesondere als Personenkraftwagen, ausgebildetes Kraftfahrzeug. Die Figur zeigt die Kühleinrichtung 10 in deren Einbaulage, wobei die Kühleinrichtung 10 in ihrer Einbaulage in vollständig hergestelltem Zustand des mit der Kühleinrichtung 10 ausgestatteten Kraftfahrzeugs einnimmt. Die Kühleinrichtung 10 weist wenigstens einen als Wärmetauscher ausgebildeten Kühler 12 auf, dessen Grundebene 14 schräg zur in der Figur durch eine beispielsweise 16 veranschaulichten Fahrzeuglängsrichtung des Kraftfahrzeugs verläuft. Der Kühler 12 weist eigensteife und somit formstabile Lamellen 18 auf, welche von einem vorzugsweise flüssigen Kühlmittel durchstrombar sind, insbesondere in Fahrzeugquerrichtung des Fahrzeugs, das in Fahrzeugquerrichtung in der Fig. durch einen Doppelpfeil 20 veranschaulicht ist. Vorzugsweise umfasst das Kühlmittel zumindest Wasser, sodass das Kühlmittel auch als Kühlwasser oder Wasser bezeichnet wird. Da somit die Lamellen 18 von dem Kühlwasser durchströmbar sind, welches mittels der Lamellen 18 geführt wird, werden die Lamellen 18 auch als kühlmittelführende oder wasserführende Lamellen bezeichnet. Außerdem sind die Lamellen 18 außenumfangsseitig von Luft umströmbar. Luft, die beispielsweise bei einer
Vorwärtsfahrt des Kraftfahrzeugs die Lamellen 18 an- und umströmt, ist in der Fig. durch einen Pfeil 22 veranschaulicht. Insbesondere veranschaulicht der Pfeil 22 eine Strömung der die Lamellen 18 an- und umströmenden Luft, die insbesondere aus einer Umgebung 24 des Kraftfahrzeugs stammt. The only figure shows a detail, in a schematic side view, of a cooling device 10 for a motor vehicle which is preferably designed as a motor vehicle, in particular as a passenger car. The figure shows the cooling device 10 in its installation position, the cooling device 10 assuming its installation position in the fully manufactured state of the motor vehicle equipped with the cooling device 10 . The cooling device 10 has at least one radiator 12 embodied as a heat exchanger, the base plane 14 of which runs obliquely to the longitudinal direction of the motor vehicle illustrated in the figure by a vehicle longitudinal direction 16, for example. The radiator 12 has inherently rigid and thus dimensionally stable fins 18 through which a preferably liquid coolant can flow, in particular in the transverse direction of the vehicle, which is illustrated in the figure by a double arrow 20 in the transverse direction of the vehicle. The coolant preferably includes at least water, so that the coolant is also referred to as cooling water or water. Since the cooling water, which is guided by means of the fins 18, can flow through the fins 18, the fins 18 are also referred to as coolant-carrying or water-carrying fins. In addition, air can flow around the outer circumference of the lamellae 18 . Air, for example, at a Forward travel of the motor vehicle against and around the slats 18 is illustrated by an arrow 22 in the figure. In particular, the arrow 22 illustrates a flow of the air flowing against and around the slats 18, which comes in particular from an environment 24 of the motor vehicle.
Der Kühler 12 weist auch einen Fluidkasten 26 auf, dessen Längserstreckungsrichtung in der Fig. durch einen Doppelpfeil 28 veranschaulicht ist. Der Fluidkasten 26 ist von dem Kühlmittel durchströmbar. Da bei dem in der Fig. gezeigten Ausführungsbeispiel das Kühlmittel flüssig ist und zumindest Wasser umfasst, wird der Fluidkasten 26 auch als Wasserkasten bezeichnet. Der Fluidkasten 26 ist ein den Lamellen 18 gemeinsamer Fluidkasten, wobei die Lamellen 18 über den Fluidkasten 26 mit dem den Fluidkasten 26 durchströmenden Kühlmittel versorgbar sind. Alternativ ist es denkbar, dass das die Lamellen 18 durchströmende Kühlmittel über den Fluidkasten 26 von den Lamellen 18 abführbar ist. Des Weiteren ist aus der Fig. erkennbar, dass die Lamellen 18 in Fahrzeughochrichtung des Kraftfahrzeugs aufeinanderfolgen und somit nacheinander angeordnet sind. Die Fahrzeughochrichtung ist in der Fig. durch einen Doppelpfeil 30 veranschaulicht. The cooler 12 also has a fluid box 26, the longitudinal direction of which is illustrated in the figure by a double arrow 28. The coolant can flow through the fluid box 26 . Since the coolant is liquid in the exemplary embodiment shown in the figure and comprises at least water, the fluid box 26 is also referred to as a water box. The fluid box 26 is a fluid box common to the fins 18 , the fins 18 being able to be supplied via the fluid box 26 with the coolant flowing through the fluid box 26 . Alternatively, it is conceivable that the coolant flowing through the fins 18 can be discharged from the fins 18 via the fluid box 26 . Furthermore, it can be seen from the figure that the slats 18 follow one another in the vertical direction of the motor vehicle and are therefore arranged one after the other. The vertical direction of the vehicle is illustrated in the figure by a double arrow 30 .
Unter der Grundebene 14 ist insbesondere Folgendes zu verstehen: Die Lamellen 18 erstrecken sich jeweils in Fahrzeuglängsrichtung von vorne nach hinten beziehungsweise umgekehrt, sodass die jeweilige Lamelle 18 beidseitig Enden, insbesondere freie Enden, aufweist, insbesondere in Fahrzeuglängsrichtung betrachtet. In Fahrzeuglängsrichtung nach hinten hin betrachtet endet die jeweilige Lamelle 18 an einem ersten ihrer Enden, und in Fahrzeuglängsrichtung nach vorne hin betrachtet, endet die jeweilige Lamelle 18 an ihrem jeweiligen, zweiten Ende. Die ersten Enden sind nun beispielsweise in einer den ersten Enden gemeinsamen, ersten Ebene angeordnet. Alternativ oder zusätzlich sind beispielsweise die jeweiligen zweiten Enden in einer jeweiligen, den zweiten Enden gemeinsamen zweiten Ebene angeordnet. Bei dem in der Fig. gezeigten Ausführungsbeispiel ist die erste Ebene die Grundebene 14, in welcher die ersten Enden der Lamellen 18 angeordnet sind beziehungsweise die Lamellen 18 enden, insbesondere in Fahrzeuglängsrichtung nach hinten hin betrachtet. Somit verläuft die erste Ebene beziehungsweise die Grundebene 14 schräg zur Fahrzeuglängsrichtung. Alternativ oder zusätzlich verläuft die zweite Ebene, welche eine weitere Grundebene des Kühlers 12 sein kann, schräg zur Fahrzeuglängsrichtung. The base plane 14 is to be understood in particular as follows: The slats 18 each extend in the longitudinal direction of the vehicle from front to rear or vice versa, so that the respective slat 18 has ends on both sides, in particular free ends, particularly when viewed in the longitudinal direction of the vehicle. Viewed backwards in the vehicle longitudinal direction, the respective slat 18 ends at a first of its ends, and viewed forwards in the vehicle longitudinal direction, the respective slat 18 ends at its respective second end. The first ends are now arranged, for example, in a first plane common to the first ends. Alternatively or additionally, for example, the respective second ends are arranged in a respective second plane common to the second ends. In the exemplary embodiment shown in the figure, the first plane is the base plane 14, in which the first ends of the slats 18 are arranged or the slats 18 end, in particular viewed towards the rear in the longitudinal direction of the vehicle. Thus, the first plane or the base plane 14 runs obliquely to the longitudinal direction of the vehicle. Alternatively or additionally, the second plane, which can be a further base plane of the cooler 12, runs at an angle to the longitudinal direction of the vehicle.
Um nun eine besonders hohe Kühlleistung sowie einen besonders geringen Bauraumbedarf des Kühlers 12 und somit der Kühleinrichtung 10 insgesamt realisieren
zu können, verlaufen die Lamellen 18 in Fahrzeuglängsrichtung betrachtet parallel zur Fahrzeuglängsrichtung und dadurch schräg zur Grundebene 14 des Kühlers 12. Mit anderen Worten weist die jeweilige Lamelle 18 eine jeweilige, von ihrem jeweiligen ersten Ende durchgängig zu einem jeweiligen zweiten Ende hin verlaufende Erstreckung auf, die bei dem in der Fig. gezeigten Ausführungsbeispiel parallel zur Fahrzeuglängsrichtung und somit schräg zur Grundebene 14 verläuft. Die Längserstreckungsrichtung des Fluidkastens 26 jedoch verläuft schräg zur Fahrzeuglängsrichtung, sodass der Fluidkasten 26 wie der Kühler 12 an sich beziehungsweise die Grundebene 14 schräg gestellt ist. Die Lamellen 18 beziehungsweise ihre jeweilige Erstreckung verlaufen beziehungsweise verläuft somit auch schräg zum Fluidkasten 26, das heißt schräg zur Längserstreckungsrichtung (Doppelpfeil 28) des Fluidkastens 26. Etwaige, in der Fig. nicht dargestellte in Fahrzeughochrichtung zwischen den wasserführenden Lamellen 18 angeordnete, luftführende Lamellen zum Führen der zwischen den Lamellen 18 hindurchströmenden Luft sind vorzugsweise an die schräg zum Fluidkasten 26 und schräg zur Grundebene 14 verlaufenden, wasserführenden Lamellen 18 angepasst. Die durch den Doppelpfeil 28 veranschaulichte Längserstreckungsrichtung des Fluidkastens 26 verläuft schräg zur Fahrzeughochrichtung und schräg zur Fahrzeuglängsrichtung, wodurch die Lamellen 18 beziehungsweise 18 beziehungsweise ihre in Fahrzeuglängsrichtung verlaufende Erstreckung schräg zum Fluidkasten 26, das heißt schräg zur Längserstreckungsrichtung des Fluidkastens 26 verlaufen beziehungsweise verläuft.
In order to achieve a particularly high cooling capacity and a particularly small installation space requirement for the cooler 12 and thus for the cooling device 10 as a whole viewed in the longitudinal direction of the vehicle, the lamellae 18 run parallel to the longitudinal direction of the vehicle and thus obliquely to the base plane 14 of the radiator 12. In other words, the respective lamella 18 has a respective extension running continuously from its respective first end to a respective second end, which in the exemplary embodiment shown in the figure runs parallel to the longitudinal direction of the vehicle and thus obliquely to the base plane 14 . However, the direction in which the fluid box 26 extends longitudinally runs at an angle to the longitudinal direction of the vehicle, so that the fluid box 26 is positioned at an angle like the cooler 12 itself or the base plane 14 . The slats 18 or their respective extension run or thus also runs obliquely to the fluid box 26, i.e. obliquely to the longitudinal direction (double arrow 28) of the fluid box 26 Guiding of the air flowing through between the lamellae 18 is preferably adapted to the water-guiding lamellae 18 running obliquely to the fluid box 26 and obliquely to the base plane 14 . The direction of longitudinal extent of fluid box 26 illustrated by double arrow 28 runs obliquely to the vertical direction of the vehicle and obliquely to the longitudinal direction of the vehicle, as a result of which the slats 18 or 18 or their extent running in the longitudinal direction of the vehicle run or runs obliquely to fluid box 26, i.e. obliquely to the direction of longitudinal extent of fluid box 26.
