Description

Die Erfindung betrifft eine kastenförmige Kühlanlage für Kraftfahrzeuge, bestehend aus kastenförmig zusammengesetzten, aus einem Kühlnetz mit Flachrohren und Rippen sowie Sammelkästen aufweisenden Kühlflüssigkeitskühlern, Ladeluftkühlern und gegebenenfalls anderen Kühlern bzw. Wärmetauschern, einem im Inneren rotierenden Radialventilator sowie einer Front - und einer Rückwand und mit mindestens einem Ausgleichsbehälter.The invention relates to a box-shaped cooling system for motor vehicles, consisting of box-shaped composed of a cooling network with flat tubes and fins and collecting boxes having coolant coolers, charge air coolers and possibly other coolers or Heat exchangers, an internally rotating radial fan as well as a front and one Rear wall and with at least one expansion tank.

Kühlflüssigkeitskühler im Kraftfahrzeug erfordern, um effektiv wirksam zu sein, in ihrer Nähe einen Raum, in dem sich die Kühlflüssigkeit ausdehnen und entgasen kann. In der Regel wird dazu ein separater Ausgleichsbehälter oder auch ein vom Sammelkasten des Kühlflüssigkeitskühlers abgetrennter Raum verwendet, der mit dem Kühlkreislauf in Verbindung steht. Solche Ausgleichsbehälter haben in aller Regel einen Einfüllstutzen, um das Kühlsystem aufzufüllen und sie erlauben außerdem, daß im Kühlsystem vorhandene Lufteinschlüsse entweichen können.
Beispielsweise wurde in der ein Kühlsystem für Brennkraftmaschinen betreffenden DE 3912734 A1 der Ausgleichsbehälter einstückig mit dem Mantel des Gebläses ausgebildet und dient als Träger für einen Kühler. Dies ist jedoch kein Hinweis zur Art und Weise der Anordnung des Ausgleichsbehälters bei den angesprochenen Kühlanlagen.
Bei kastenförmigen Kühlanlagen in Kraftfahrzeugen, die Kühlflüssigkeitskühler enthalten, ist unter den restriktiven Forderungen der Anwender solcher Kühlanlagen die Anordnung eines Ausgleichsbehälters und dessen Einbindung in das Kühlsystem mit Problemen behaftet.
Die Aufgabe der Erfindung besteht darin, für die genannte Kühlanlage einen Ausgleichsbehälter vorzusehen, der sowohl hinsichtlich der Gesamtkosten der Kühlanlage als auch hinsichtlich seiner Funktion den Forderungen der Anwender vollständig entspricht.
Erfindungsgemäß ist vorgesehen, daß der Ausgleichsbehälter so angeordnet ist, daß seine Projektionsfläche die Fläche des Kühlnetzes mindestens eines Kühlers zu einem wesentlichen Teil abdeckt und der Ausgleichsbehälter die Kühlluft ableitet.In order to be effective, automotive coolant coolers require a space in their vicinity where the coolant can expand and degas. As a rule, a separate expansion tank or a space separated from the coolant cooler header is used for this purpose, which is connected to the cooling circuit. Such expansion tanks usually have a filler neck to fill the cooling system and they also allow existing air pockets in the cooling system to escape.
For example, in DE 3912734 A1, which relates to a cooling system for internal combustion engines, the expansion tank was formed in one piece with the jacket of the fan and serves as a carrier for a cooler. However, this is not an indication of the manner in which the expansion tank is arranged in the cooling systems mentioned.
In the case of box-shaped cooling systems in motor vehicles which contain coolant coolers, the arrangement of a compensating container and its integration into the cooling system is fraught with problems under the restrictive requirements of the users of such cooling systems.
The object of the invention is to provide an expansion tank for the cooling system mentioned, which fully meets the requirements of the users both in terms of the total costs of the cooling system and in terms of its function.
According to the invention it is provided that the expansion tank is arranged so that its projection surface covers the surface of the cooling network of at least one cooler to a substantial extent and the expansion tank derives the cooling air.

Vorzugsweise befindet sich der Ausgleichsbehälter oberhalb des oberen horizontal angeordneten Ladeluftkühlers und ist in einem optimierten Abstand von demselben angeordnet, wobei der Boden des Ausgleichsbehälters die Funktion eines Luftleitbleches oder dergleichen besitzt. Als optimierter Abstand wird ein solcher Abstand verstanden, der die Leitung der aus dem Kühlnetz austretenden Kühlluft wirksam in eine gewollte Richtung unterstützt.
Vorzugsweise erhält der Ausgleichsbehälter einen günstigen Platz am höchsten Punkt der Kühlanlage, um seine Funktion der Entgasung der Kühlflüssigkeit erfüllen zu können. Ferner führt die Ausbildung des Bodens des Ausgleichsbehälters als Luftleitblech dazu, daß der vorhandene Strömungswiderstand in vertretbaren Grenzen bleibt.
Es hat sich überraschend erwiesen, daß der Ausgleichsbehälter, wenn er in einem optimierten Abstand vom Kühlnetz entfernt vorgesehen wird, die Leistung des Kühlers nur unwesentlich, jedenfalls nur in einem vertretbaren Umfang mindert. Die vom Radialventilator durch die Öffnung in der Frontplatte der Kühlanlage angesaugte Kühlluft wird radial umgelenkt und durch die Kühlnetze der Kühler gedrückt. Die aus dem Kühlnetz austretende Kühlluft erreicht auch den abgedeckten Bereich des Kühlnetzes, um dort ihre Kühlfunktion zu erfüllen und wird um den Ausgleichsbehälter herum gelenkt. Die Kühlwirkung kann vorteilhafter Weise zusätzlich durch Luftleitelemente unterstützt werden.
In einem anderen Ausführungsbeispiel oder zusätzlich kann der Ausgleichsbehälter schräg angeordnet sein, so daß seine Bodenfläche mit der Ebene des Kühlnetzes einen spitzen Winkel bildet, wodurch der Ausgleichsbehälter selbst wie ein Luftleitelement wirken kann. Der erwähnte optimierte Abstand vom Kühlnetz ist bei diesem Ausführungsbeispiel nicht konstant, sondern steigt entsprechend der Steigung an. Dabei kann der Abstand auf einer Seite auch den Wert 0 betragen, d.h. der Ausgleichsbehälter stützt sich auf der besagten Seite direkt am Kühlnetz ab bzw. er berührt das Kühlnetz. Schließlich kann die Bodenfläche des Ausgleichsbehälters eine strömungstechnisch günstige Form erhalten, die den Einsatz von separaten Luftleitelementen erübrigt.
Ferner kann die Leistungseinbuße durch die Verwendung eines Radialventilators kompensiert werden, der bei gleicher Leistungsaufnahme deutlich höhere Luftfördermengen als ein Axialventilator aufweist.
Die Befestigung des Ausgleichsbehälters wird vorzugsweise direkt am Kühlnetz vorgenommen. Dazu sind in von Wellrippen freien Ausschnitten Halter zwischen den Flachrohren des Kühlnetzes angeordnet, die mit den Flachrohren metallisch verbunden sind und eine ausreichend stabile Befestigung und Abstützung erlauben.
Die erfindungsgemäße Lösung ist hinsichtlich der Gesamtkosten für die Kühlanlage, im Vergleich mit Kühlanlagen, die den Ausgleichsbehälter an einem Sammelkasten vorsehen, sehr günstig, weil standardmäßige Sammelkästen für die Kühler der Kühlanlage verwendet werden können. Bei der erfindungsgemäßen Lösung können auch sehr einfach Ausgleichsbehälter unterschiedlicher Größe eingesetzt werden, ohne daß weitgehende Änderungen an den übrigen Teilen der Kühlanlage erforderlich werden.
Die Erfindung wird nachfolgend in einem Ausführungsbeispiel beschrieben. Die beiliegenden Figuren zeigen:

  • Fig. 1 Seitenansicht der Kühlanlage;
  • Fig. 2 Ansicht von hinten auf die Kühlanlage;
  • Fig. 3 Ansicht von vorne auf die Kühlanlage;
  • Fig. 4 Perspektivansicht auf den Ladeluftkühler mit dem Ausgleichsbehälter;
  • Fig. 5 Draufsicht von Fig. 4;
  • Fig. 6 Einzelheit der Befestigung
    • Die kastenförmige Kühlanlage 1 besteht aus einem im Bild oben angeordneten Ladeluftkühler 2, der Sammelkästen 10; 11, einen Ladelufteinlass 21, einen Ladeluftauslass 22 und ein Kühlnetz 8 aufweist, das nicht gezeichnet wurde. Das Kühlnetz 8 ist jedoch prinzipiell identisch mit dem Kühlnetz 8 des Kühlflüssigkeitskühlers 3, das aus Fig. 1 hervorgeht. Das Kühlnetz 8 besteht aus Flachrohren 7 und zwischen den Flachrohren 7 angeordneten Wellrippen 6. Die Enden der Flachrohre 7 sind mit gegenüberliegenden Sammelkästen 10 und 11 verbunden. Die Kühlflüssigkeit oder die zu kühlende Ladeluft strömt auf dem Weg vom Sammelkasten 10 zum Sammelkasten 11 durch die Flachrohre 7 und wird mittels Kühlluft, die durch die Wellrippen 6 strömt, gekühlt. Die Kühlluft wird von einem Radialventilator 14 durch eine in der Frontwand 16 angeordnete Öffnung 20 mit einer Einströmdüse 15 (Fig. 3) angesaugt und durch die Kühlnetze 8 sämtlicher Kühler der Anordnung befördert. Die Kühlanlage 1 ist an der Rückseite mittels der Rückwand 17 verschlossen. The expansion tank is preferably located above the upper, horizontally arranged charge air cooler and is arranged at an optimized distance therefrom, the bottom of the expansion tank having the function of an air baffle or the like. An optimized distance is understood to be a distance which effectively supports the conduction of the cooling air emerging from the cooling network in a desired direction.
    The expansion tank is preferably given a favorable place at the highest point of the cooling system in order to be able to perform its function of degassing the cooling liquid. Furthermore, the design of the bottom of the expansion tank as an air baffle means that the existing flow resistance remains within reasonable limits.
    It has surprisingly been found that the expansion tank, if it is provided at an optimized distance from the cooling network, only insignificantly reduces the performance of the cooler, in any case only to an acceptable extent. The cooling air drawn in by the radial fan through the opening in the front plate of the cooling system is deflected radially and pressed through the cooling networks of the coolers. The cooling air emerging from the cooling network also reaches the covered area of the cooling network in order to fulfill its cooling function there and is directed around the expansion tank. The cooling effect can advantageously also be supported by air guiding elements.
    In another embodiment or in addition, the expansion tank can be arranged obliquely so that its bottom surface forms an acute angle with the plane of the cooling network, as a result of which the expansion tank itself can act as an air guiding element. The above-mentioned optimized distance from the cooling network is not constant in this exemplary embodiment, but increases in accordance with the gradient. The distance on one side can also be 0, ie the expansion tank is supported directly on the cooling network on the said side or touches the cooling network. Finally, the bottom surface of the expansion tank can be given a shape which is favorable in terms of flow technology and which makes the use of separate air guiding elements unnecessary.
    Furthermore, the loss of power can be compensated for by using a radial fan which, with the same power consumption, has significantly higher air flow rates than an axial fan.
    The expansion tank is preferably attached directly to the cooling network. For this purpose, holders are arranged in cutouts free of corrugated fins between the flat tubes of the cooling network, which are metallically connected to the flat tubes and permit sufficiently stable fastening and support.
    The solution according to the invention is very inexpensive in terms of the total costs for the cooling system, in comparison with cooling systems which provide the expansion tank on a collecting tank, because standard collecting boxes can be used for the coolers of the cooling system. In the solution according to the invention, expansion tanks of different sizes can also be used very easily without extensive changes to the remaining parts of the cooling system being necessary.
    The invention is described below in an exemplary embodiment. The attached figures show:
  • Fig. 1 side view of the cooling system;
  • Fig. 2 rear view of the cooling system;
  • Fig. 3 front view of the cooling system;
  • Fig. 4 perspective view of the charge air cooler with the expansion tank;
  • Fig. 5 top view of Fig. 4;
  • Fig. 6 detail of the attachment
    • The box-shaped cooling system 1 consists of a charge air cooler 2, the collecting boxes 10; 11, a charge air inlet 21, a charge air outlet 22 and a cooling network 8, which was not drawn. In principle, however, the cooling network 8 is identical to the cooling network 8 of the coolant cooler 3, which is shown in FIG. 1. The cooling network 8 consists of flat tubes 7 and corrugated fins 6 arranged between the flat tubes 7. The ends of the flat tubes 7 are connected to opposite collecting boxes 10 and 11. The cooling liquid or the charge air to be cooled flows on the way from the collecting box 10 to the collecting box 11 through the flat tubes 7 and is cooled by means of cooling air which flows through the corrugated fins 6. The cooling air is drawn in by a radial fan 14 through an opening 20 arranged in the front wall 16 with an inflow nozzle 15 (FIG. 3) and conveyed through the cooling networks 8 of all coolers of the arrangement. The cooling system 1 is closed at the rear by means of the rear wall 17.

    Der Ausgleichsbehälter 4 enthält Kühlflüssigkeit und ist strömungstechnisch in nicht gezeigter Weise z. B. mit dem Kühlflüssigkeitskühler 3 verbunden und ist Bestandteil des Kreislaufes. Er ist am höchsten Punkt der Kühlanlage 1 angeordnet, damit dort Gaseinschlüsse aus der Kühlflüssigkeit entweichen können. Zum Auffüllen des Systems ist ein Einfüllstutzen 13 am Ausgleichsbehälter 4 angeordnet. Der Ausgleichsbehälter 4 hat einen Abstand a vom Kühlnetz 8 des Ladeluftkühlers 2. Wie auch die Fig. 2 zeigt, deckt der Ausgleichsbehälter 4 in diesem Ausführungsbeispiel die gesamte Fläche des Kühlnetzes 8 ab. Dadurch kann der Ausgleichsbehälter 4 bei gleichem Fassungsvermögen mit geringerer Bauhöhe ausgeführt werden, wodurch die Gesamtbauhöhe der Kühlanlage 1 reduziert wird. Der Boden 5 des Ausgleichsbehälters 4 hat in diesem Ausführungsbeispiel keinen konstanten Abstand a zum Kühlnetz 8. Der Abstand a steigt von der Vorderseite zur Rückseite der Kühlanlage 1 an, wodurch der Boden 5 die Funktion eines Luftleitbleches einnimmt und den überwiegenden Anteil der abströmenden Kühlluft (Pfeile in Fig. 1) entweder zur weiteren Nutzung oder ins Freie ableitet. Dort wo der geringe Abstand a vorhanden ist, hat es sich als vorteilhaft herausgestellt, diesen Abstand a mit einem Abdeckblech 9 zu schließen, um die Kühlluft gezielt abzuführen. Insgesamt beeinträchtigt eine solche Anordnung des Ausgleichsbehälters 4 die Kühlleistung nur unwesentlich und ist ein ausgezeichneter Kompromiß hinsichtlich einer hohen Kühlleistung bei kompakter Gestaltung der gesamten Kühlanlage und dem Erfordernis der Anordnung des Ausgleichsbehälters 4, als Voraussetzung für ein funktionierendes Kühlsystem des Kraftfahrzeuges. Der Ausgleichsbehälter 4 ist mittels Halter 12 am Ladeluftkühler 2 befestigt worden.
    Eine vorteilhafte Befestigung des Ausgleichsbehälters ist in den Fig. 4 und 5 gezeigt worden. Die beiden Figuren zeigen lediglich den Ladeluftkühler 2 oder einen Teil davon und den Ausgleichsbehälter 4. Die gezeigte Befestigung kommt hauptsächlich dann zur Anwendung, wenn ein Ausgleichsbehälter 4 verwendet werden kann, der einen kleineren Teil der Fläche des Kühlnetzes 8 abdeckt als in den Fig. 1 bis 3 gezeigt wurde. Es sind von Wellrippen 6 freie Bereiche vorgesehen, in denen die Halter 12 mit einem Ende zwischen den Flachrohren 7 eingesetzt wurden. Da vorzugsweise gelötete Kühlnetze 8 verwendet werden, sind die Halter 12 mit den Flachrohren 7 mittels Löten verbunden. Die Fig. 6 zeigt einen Querschnitt durch den Ladeluftkühler 2 im Bereich der Halter 12. Der Ladeluftkühler 2 weist zwei Rohrreihen auf. Das Ende der Halter 12 reicht über beide Rohrreihen, um ausreichende Haltbarkeit zu bieten.    The expansion tank 4 contains cooling liquid and is fluidically in a manner not shown z. B. connected to the coolant cooler 3 and is part of the circuit. It is arranged at the highest point of the cooling system 1 so that gas inclusions can escape from the cooling liquid. To fill the system, a filler neck 13 is arranged on the expansion tank 4. The expansion tank 4 is at a distance a from the cooling network 8 of the charge air cooler 2. As also shown in FIG. 2, the expansion tank 4 covers the entire area of the cooling network 8 in this exemplary embodiment. As a result, the expansion tank 4 can be designed with the same capacity with a lower overall height, as a result of which the overall overall height of the cooling system 1 is reduced. In this exemplary embodiment, the base 5 of the expansion tank 4 is not at a constant distance a from the cooling network 8. The distance a increases from the front to the rear of the cooling system 1, as a result of which the base 5 assumes the function of an air baffle and the majority of the cooling air flowing out (arrows in Fig. 1) either for further use or in the open. Where the small distance a is present, it has proven to be advantageous to close this distance a with a cover plate 9 in order to remove the cooling air in a targeted manner. Overall, such an arrangement of the expansion tank 4 only insignificantly affects the cooling capacity and is an excellent compromise with regard to a high cooling capacity with a compact design of the entire cooling system and the requirement for the arrangement of the expansion tank 4 as a prerequisite for a functioning cooling system of the motor vehicle. The expansion tank 4 has been fastened to the charge air cooler 2 by means of a holder 12.
    An advantageous attachment of the expansion tank has been shown in FIGS. 4 and 5. The two figures only show the charge air cooler 2 or a part thereof and the expansion tank 4. The attachment shown is mainly used when a expansion tank 4 can be used, which covers a smaller part of the surface of the cooling network 8 than in FIG. 1 to 3 was shown. Areas free of corrugated fins 6 are provided, in which the holders 12 have been inserted with one end between the flat tubes 7. Since preferably soldered cooling networks 8 are used, the holders 12 are connected to the flat tubes 7 by means of soldering. 6 shows a cross section through the charge air cooler 2 in the area of the holder 12. The charge air cooler 2 has two rows of pipes. The end of the holder 12 extends over both rows of pipes to provide sufficient durability.
