Die Erfindung betrifft eine Kühleranordnung bestehend aus mehreren Kühlern, die je zwei mit Verbindungsrändern ausgestattete Sammelkästen aufweisen, zur Kühlung verschiedener Fluide, deren in mindestens einer Reihe angeordnete, die Sammelkästen verbindende Flachrohre quer zur Ventilatorachse des im Inneren der Kühleranordnung angeordneten Radialventilators verlaufen, mit einer Frontwand und einer Rückwand so eine Kühleranordnung ist aus der DE-C- 197 13712 bekannt.The invention relates to a radiator assembly consisting of a plurality of radiators, each having two equipped with connecting edges collecting boxes, for cooling various fluids, arranged in at least one row, connecting the manifolds flat tubes extending transversely to the fan axis of the arranged inside the radiator assembly radial fan, with a front wall and a rear wall such a cooler arrangement is known from DE-C-197 13712.
In der DE 199 50 753.8 sind die Zu - und Abflußleitungen der Kühleranordnung relativ flach und damit platzsparend ausgebildet. Sie verbinden die beiden in der dortigen Fig. 1 seitlichen und den unten angeordneten Kühler, die dort Kühlflüssigkeitskühler sind. Der Ein - bzw. der Austritt der Zu - oder Abflußleitungen in bzw. aus dem jeweiligen Sammelkasten erfolgt dort über die Stirnseiten des jeweiligen Sammelkastens. Der Zulauf und der Ablauf der Kühlflüssigkeit befindet sich an der Rückwand. Mit einer solchen Ausbildung kann nicht allen Einsatz - bzw. Anschlußbedingungen entsprochen werden.In DE 199 50 753.8 the inflow and outflow lines of the radiator arrangement are relatively flat and thus space-saving. They connect the two in the local Fig. 1 side and the bottom mounted radiator, which are cooling liquid cooler there. The inflow or outflow of the inflow or outflow lines into or out of the respective collection box takes place via the end faces of the respective collection box. The inlet and the outlet of the cooling liquid is located on the rear wall. With such a training, not all application or connection conditions can be met.
Die genannte bisher unveröffentlichte Kühleranordnung besteht aus Kühlern, die Sammelkästen mit Rohrböden aufweisen, wie in Fig. 4 der erwähnten Anmeldung gezeigt ist.Said previously unpublished cooler assembly consists of coolers having headers with tube plates, as shown in Fig. 4 of the aforementioned application.
Ferner gibt es Kühler, die als sogenannte rohrbodenlose Kühler bezeichnet werden können. Solche Kühler gehen u. a. aus den bisher Anmeldungen DE 100 16 113. 8, DE 100 19 268.8 oder DE 100 33 070.3 hervor. Aus dem EP 222 636 A1 geht ein Kühler hervor, bei dem ein Anschlussstutzen aus Kunststoff einstückig mit dem Sammelkasten bzw. mit einem Rohrboden ausgebildet ist.There are also coolers that can be referred to as so-called tube bottomless cooler. Such coolers go u. a. from the previously applications DE 100 16 113. 8, DE 100 19 268.8 or DE 100 33 070.3. From EP 222 636 A1, a cooler is apparent, in which a connecting piece made of plastic is formed integrally with the collecting box or with a tube bottom.
Die Aufgabe der Erfindung besteht darin, die Kühleranordnung so auszubilden, daß sie für andere Einsatz - bzw. Anschlußbedingungen geeignet ist, wobei die kompakte und raumsparende Gestaltung erhalten bleiben soll.The object of the invention is to design the cooler arrangement in such a way that it is suitable for other application or connection conditions, wherein the compact and space-saving design is to be retained.
Die erfindungsgemäße Lösung ergibt sich hinsichtlich der Kühleranordnung aus dem Kennzeichen des Anspruchs 1. Die Ansprüche 2 bis 9 beschreiben Varianten und Weiterbildungen der Kühleranordnung.The solution according to the invention results with regard to the cooler arrangement from the characterizing part of
Gemäß dem Anspruch 1 ist vorgesehen, eine Kühleranordnung mit an die Sammelkasten angeschlossen Zu- und Abflußleitungen zur Strömungstechnisch Verbindung mehrerer kühler, wobei in direkter oder indirekter Nachbarschaft zu dem Ende des ersten und / oder letzten Flachrohrs der mindestens einen Flachrohr - Reihe ein Anschlußstutzen angeordnet ist, dessen Mündung in den Sammelkasten in einer Reihe mit den Mündungen der Flachrohre in den Sammelkasten vorgesehen ist und der den Anschluß der Zu - oder Abflußleitung derAccording to
Kühler gestattet.Cooler allowed.
Durch die erfindungsgemäße Ausbildung eignet sich die Kühleranordnung und der Kühler insbesondere für Anschlußbedingungen, bei denen die Zu - oder Abflußleitungen in unmittelbarer Nähe der Kühleranordnung oder des Kühlers angeordnet sind. Bei Kühleranordnungen und Kühlern aus dem Stand der Technik werden Anschlußstutzen gewöhnlich in der Wandung des Sammelkastens plaziert, die dann mit einer entsprechenden Öffnung mit einem Lötrand versehen werden muß. Gegenüber solchen Lösungen führt die vorliegende Erfindung zu reduziertem Fertigungsaufwand. Der Kühler führt also nicht nur im Zusammenhang mit der Kühleranordnung zu den erwähnten Vorteilen, sondern auch dann, wenn er als einzelner Kühler angewendet wird. Weil die flachen Zu - und Abflußleitungen in Nachbarschaft zu dem Ende des am weitesten außen liegenden bzw. des ersten und/oder letzten Flachrohrs der Reihe in den Sammelkasten ein - oder austreten, ist die Kühleranordnung bezüglich ihrer Kompaktheit weiter verbessert worden, denn in der Anmeldung ist der Ein - und Austritt von den Stirnseiten der Sammelkästen vorgesehen worden, also quer zur Richtung der Flachrohre und nicht in einer Reihe dazu, wodurch etwas mehr Raum beansprucht wird.The inventive design, the radiator assembly and the radiator is particularly suitable for connection conditions in which the inflow or outflow lines are arranged in the immediate vicinity of the radiator assembly or the radiator. In prior art radiator assemblies and coolers, spigots are usually placed in the wall of the header tank, which must then be provided with a corresponding opening with a soldering rim. Compared to such solutions, the present invention leads to reduced manufacturing costs. The cooler thus leads not only in connection with the cooler arrangement to the mentioned advantages, but also when it is used as a single cooler. Because the shallow inlet and outlet conduits enter or exit the collection box adjacent to the end of the outermost or first and / or last flat tube of the row, the cooler arrangement has been further improved in compactness, as in the application the entry and exit has been provided by the end faces of the collecting boxes, ie transversely to the direction of the flat tubes and not in a row, whereby a little more space is claimed.
Unter direkter Nachbarschaft ist zu verstehen, daß sich das Ende des Flachrohrs und der Anschlußstutzen der Zu - oder Ablaufleitungen berühren oder kein Bauteil zwischen sich haben, wohingegen bei der indirekten Nachbarschaft z. B. das Ende einer Wellrippe und / oder eines Seitenteils des jeweiligen Kühlers und / oder ein Rohrbodenabschnitt zwischen dem Ende des Flachrohrs und dem Anschlußstutzen angeordnet ist.By direct neighborhood is to be understood that touch the end of the flat tube and the connecting piece of the inlet or outlet lines or have no component between them, whereas in the indirect neighborhood z. B. the end of a corrugated fin and / or a side part of the respective radiator and / or a tube bottom portion between the end of the flat tube and the connecting piece is arranged.
Die Kühler der Anordnung bestehen entweder (und vorzugsweise) aus Kühler, die Rohrböden besitzen, wie diejenigen aus der Anmeldung DE 199 50 753.8 (Ansprüche 2 und 3) oder zumindest einige der Kühler können auch gemäß den Anmeldungen DE 100 16 113. 8, DE 100 19 268.8 oder DE 100 33 070.3 ohne Rohrboden ausgebildet sein, (Ansprüche 4 und 5). Auf diese Anmeldungen wird ausdrücklich Bezug genommen. Hier nicht erwähnte Merkmale, die unter Umständen für die Ausführbarkeit erforderlich sein könnten, sind in letzteren Anmeldungen enthalten.The coolers of the arrangement consist either (and preferably) of coolers having tubesheets, such as those of the application DE 199 50 753.8 (
Zwischen der Zulauf - oder der Ablaufleitung und dem jeweiligen Sammelkasten sind Anschlußstutzen angeordnet. Die Anschlußstutzen besitzen vorzugsweise einen rechteckigen Strömungsquerschnitt. Das eine Ende des Anschlußstutzens ist so ausgebildet, daß das Ende der Zu - oder Ablaufleitung vorzugsweise mittels Steckverbindung angeschlossen werden kann. Die Steckverbindung selbst kann bekannter Ausführung sein. Die Anschlußstutzen bestehen aus Aluminium und sie sind je nach Bedarf mit Lot beschichtet, so daß sie bei der Herstellung des jeweiligen Kühlers der Kühleranordnung gleich mit eingesetzt und verlötet werden können.Between the inlet - or drain line and the respective collection box connecting pieces are arranged. The connecting pieces preferably have a rectangular flow cross-section. The one end of the connecting piece is designed so that the end of the inlet or outlet line can preferably be connected by means of plug connection. The connector itself may be known. The connecting pieces are made of aluminum and they are coated with solder as needed, so that they can be used in the production of the respective radiator of the cooler assembly with equal and soldered.
Wenn Kühler mit Rohrböden zum Einsatz kommen, ist im Rohrboden eine mit dem Anschlußstutzen korrelierende Öffnung vorhanden. Die Öffnung ist von einem Durchzug umgeben, der einen geeigneten Lötrand zur Verbindung mit dem Anschlußstutzen bildet.If coolers with tubesheets are used, there is an opening in the tubesheet which correlates with the connecting piece. The opening is surrounded by a passage, which forms a suitable soldering edge for connection to the connecting piece.
Bei "rohrbodenlosen" Kühlern ist das in den Sammelkasten mündende eine Ende des Anschlußstutzens ähnlich den Enden der Flachrohre zu einem Rechteck umgeformt. Die eine Längsseite des Rechtecks liegt an der Längsseite des am weitesten außen liegenden Flachrohres oder an einem Seitenteil an. Die gegenüberliegende Längsseite ist dem Verbindungsrand der Stirnwand des Sammelkastens umfaßt und die beiden kurzen Seiten des Rechtecks sind von den Verbindungsrändern beider Längsseiten des Sammelkastens eingefaßt.In the case of "tube-bottomless" coolers, one end of the connecting piece opening similar to the ends of the flat tubes is formed into a rectangle in the collecting box. The one longitudinal side of the rectangle is located on the longitudinal side of the outermost flat tube or on a side part. The opposite longitudinal side is the connecting edge of the end wall of the collecting tank comprises and the two short sides of the rectangle are bordered by the connecting edges of both longitudinal sides of the collecting tank.
Es ist von Vorteil, wenn die Zu - und Ablaufleitungen aus Krümmern, Muffen, T-Stücken, Kreuzstücken und geraden oder gebogenen Leitungsabschnitten je nach Bedarf baukastenartig zusammensteckbar sind. Dadurch können Kühleranordnungen, wobei unterschiedliche Kühler der Anordnung strömungstechnisch verbunden sind, wie beispielsweise im Anspruch 7 beschrieben, wirtschaftlicher und unter Verwendung von Gleichteilen hergestellt werden.It is advantageous if the inlet and outlet lines of elbows, sleeves, T-pieces, cross pieces and straight or bent line sections can be assembled in a modular manner as required. As a result, cooler arrangements, wherein different coolers of the arrangement are fluidically connected, as described for example in claim 7, can be produced more economically and using identical parts.
Die Krümmer, Muffen, T - Stücke und Kreuzstücke sind vorzugsweise Kunststoff- Spritzgussteile, während die Leitungsabschnitte vorzugsweise aus Aluminium bestehen, beispielsweise als Strangpressprofile ausgebildet sind.The elbows, sleeves, T - pieces and cross pieces are preferably plastic injection molded parts, while the pipe sections are preferably made of aluminum, for example, formed as extruded profiles.
Die Anordnung der Zu - und Abflußleitungen ist so gewählt, daß die Strömungswiderstände zu allen beteiligten Kühlern etwa gleich groß sind, so daß die Menge des zu kühlenden Mittels, die durch jeden Kühler strömt, ohne Verwendung von Klappen oder anderen Regulierungsorganen etwa gleich groß ist.The arrangement of the inlet and outlet lines is chosen so that the flow resistance to all the coolers involved are about the same size, so that the amount of the agent to be cooled, which flows through each cooler is about the same size without the use of flaps or other regulatory organs.

In Fig. 1 ist der obere Kühler 1 und der untere Kühler 2 der Kühleranordnung zu erkennen, sowie ein von der Kühleranordnung eingeschlossener Radialventilator 10 mit einer Ventilatorachse V. Die Kühleranordnung hat eine Frontwand F und eine Rückwand R. Die Flachrohre 8 sämtlicher Kühler 1, 2, 6 verlaufen quer zur Ventilatorachse V. Sie wurden in Fig. 1 lediglich im oberen Kühler eingezeichnet. An der Rückwand R befinden sich Zuflußleitungen 3z und an der Frontwand F Abflußleitungen 3a. Die Kühler 2, 6 und 7 sind Kühlflüssigkeitskühler, die mittels der Zu - und Abflußleitungen 3z und 3a verbunden sind. Der Kühler 7 ist gegenüber dem Kühler 6 angeordnet, wie aus Fig. 3 verständlich wird. In den Fig. 1 bis 5 wurden Pfeile 4 eingezeichnet, welche die Durchströmungsrichtung der Leitungen 3z, 3a und der Kühler 2, 6, 7 in den nicht gezeigten Flachrohren 8 anzeigen. Die Flachrohre 8 verlaufen also in Richtung der in den Fig. 2, 3 und 5 in den Kühlern 2 oder 6 eingezeichneten Pfeile 4 und damit quer zur in Fig. 1 eingezeichneten Vertilatorachse V. Der Einritt der Kühlflüssigkeit ist im Eckbereich E an der Rückwand R angeordnet. (Fig. 4) Der Austritt befindet sich im diagonalen Eckbereich E an der Frontwand F. (Fig. 3) Wie aus der Fig. 2 u. a. zu sehen ist, haben die Kühler 1, 2, 6 und 7 jeweils zwei Sammelkästen 5, wobei jeweils zwei Sammelkästen 5 benachbarter Kühler 2, 6 eine Kante der Kühleranordnung ausbilden, wo sie eng aneinanderliegen, um die Kühleranordnung abzuschließen und dadurch die vom Radialventilator 10 angesaugte Kühlluft zwingen, zwischen den Flachrohren 8 der Kühler hindurchzuströmen. Aus den Fig. 2 und 4 sind die aneinanderliegenden Sammelkästen 5 zu erkennen. 1 , the
Bezug nehmend auf die Fig. 3 und 4 kann erkannt werden, daß die Zuflußleitungen 3z und die Abflußleitungen 3a aus geraden Leitungsabschnitten 23, aus gebogenen Leitungsabschnitten 26, aus Krümmern 24 und Kreuzstücken 25 bestehen, die mittels Anschlußmuffen 13 verbunden sind. Sie sind unter Verwendung von Dichtungen zusammensteckbar. Die geraden und gebogenen Leitungsabschnitte 23 ; 26 bestehen aus stranggepreßten Aluminiumprofilen. Die Krümmer 24 sowie die Kreuzstücke 25 sind Kunststofformteile. Mit einer solchen Ausbildung lassen sich beliebige Schaltungsvarianten, d. h. strömungstechnische Verbindungen mehrerer Kühler, kostengünstig realisieren.Referring to Figs. 3 and 4, it can be seen that the
Die Zu - und die Abflußleitungen 3z und 3a wurden nun in ganz besonderer Weise an die Sammelkästen 5 angeschlossen, wodurch die Kühleranordnung aber auch jeder einzelne Kühler eine sehr kompakte und raumsparende Gestalt erhält. Die in den Fig. 1 bis 5 eingekreisten Anschlüsse A sind in den Fig. 6 bis 12 in mehreren Varianten näher dargestellt und sollen nachfolgend beschrieben werden. Wie die genannten Figuren zeigen, wurde lediglich der Anschluß A an jeweils einzelne Kühler 2, 6 oder 7 gezeigt, die dann, wie vorstehend beschrieben, zur Kühleranordnung zusammengefügt werden können. Die Fig. 6 bis 8 bilden eine Variante ab, in der Kühler 2, 6, 7 verwendet werden, die über gegenüberliegende Rohrböden 11 verfügen, wovon nur einer gezeigt ist. Die Rohrböden 11 haben in bekannter Weise eine Reihe von Öffnungen, in denen die Enden der Flachrohre 8 münden, sie bilden Mündungen 22. Ferner haben die Rohrböden 11 einen Überstand 17, d. h. sie gehen deutlich über das erste oder letzte Flachrohr 8.1 der Flachrohr-Reihe hinaus. Der Überstand 17 ist von dem Ende des Sammelkastens 5 mit umfaßt, wie die Fig. 6 zeigt. In dem Überstand 17 befindet sich eine Öffnung 15, in der das Ende eines Anschlußstutzens 12 hinein paßt und dadurch die Mündung 21 bildet. Die Öffnung 15 hat einen Durchzug 18, vergleichbar mit den Durchzügen 18 an den für die Flachrohre 8 vorgesehenen Öffnungen, welche die Mündungen 22 bilden. Im Ausführungsbeispiel sind die Durchzüge 18 nach innen angebracht worden bzw. gerichtet. In anderen nicht gezeigten Ausführungsbeispielen weisen die Durchzüge 18 zum aus den Flachrohren 8 und den Wellrippen 9 bestehenden Kühlnetz hin, also nach außen. Aus Fig. 6 ist insbesondere die in diesem Fall indirekte Nachbarschaft zwischen dem Anschlußstutzen 12 und dem letzten Flachrohr 8.1 der Flachrohr-Reihe zu erkennen. Indirekt ist die Nachbarschaft deshalb, weil der Kühler ein Seitenteil 16 und eine äußere Wellrippe 9 aufweist, die zwischen dem Anschlußstutzen 12 und dem Flachrohr 8.1 angeordnet sind. Wie insbesondere die Fig. 7 und 8 deutlich machen, ist die Mündung 21 des Anschlußstutzens 12 in einer Reihe mit den Mündungen 22 der Flachrohre 8; 8.1 angeordnet worden. Der Querschnitt des Anschlußstutzens 12, im Bereich seiner Mündung 21, ist in diesem Ausführungsbeispiel etwa rechteckig ausgeformt. Er kann jedoch beliebig, beispielsweise auch rund ausgeformt sein, wobei natürlich die Öffnung im Rohrboden 11 die gleiche Form haben muß. Der Anschlußstutzen 12 besitzt außerdem am der Mündung 21 entgegengesetzten Ende eine Anschlußmuffe 13, die dem Anschluß der Zu - oder Abflußleitung 3z; 3a dient, wie vorstehend bereits erläutert wurde. Die Sammelkästen 5 können z. B. aus Aluminium bestehen, wobei dann die Verbindungsränder 20 der Sammelkästen 5 mit den Rohrböden 11 und gleichzeitig alle anderen Einzelteile mittels Löten verbunden werden können. Diese Ausführungsart läßt jedoch auch die Verwendung von Sammelkästen 5 aus Kunststoff zu, wobei dann die Verbindungsränder 20 mit den Rohrböden 11 in bekannter Weise mechanisch und dicht verbunden werden müssen.The inlet and
Die Fig. 9 bis 11 und die Fig. 12 zeigen zwei weitere Varianten des Anschlusses A. Hierbei handelt es sich um Kühler, die keine Rohrböden 11 aufweisen. Zunächst wird die Variante aus den Fig. 9 bis 11 beschrieben. Die Enden 30 der Flachrohre 8; 8.1 besitzen Abbiegungen und zwar so, daß die Enden 30 mit den Längsseiten 31 benachbarter Flachrohre 8 aneinanderliegen und mittels Löten verbunden werden können. In indirekter Nachbarschaft zum ersten Flachrohr 8.1 ist der Anschlußstutzen 12 angeordnet. Dazwischen befindet sich das Ende einer Wellrippe 9 und eines Seitenteils 16. Die Mündungen 22 der Flachrohre 8; 8.1 und die Mündung 21 des Anschlußstutzens 12 liegen auch hierbei in einer Reihe, wie aus den Fig. 10 und 11 zu sehen ist. Die Mündung 21 des Anschlußstutzens 12 wurde etwa rechteckförmig umgeformt. Nachdem die Flachrohre 8; 8.1, die Wellrippen 9 und der Anschlußstutzen 12 zusammengefügt worden sind, wird der in Fig. 9 teilweise gezeichnete Sammelkasten 5 angesetzt, und zwar so, daß seine Verbindungsränder 20 die Enden 30 der Flachrohre 8; 8.1 an den Schmalseiten 32 und das Ende des Anschlußstutzens 12 umfassen. Da der gesamte Kühler dieses Ausführungsbeispiels aus Aluminium besteht, können sämtliche Verbindungen mit einer Lötoperation erledigt werden. Wie aus der vorstehenden Beschreibung zu sehen ist, eignet sich diese Variante also insbesondere für vollständig aus Aluminium hergestellte Kühler.FIGS. 9 to 11 and FIG. 12 show two further variants of the connection A. These are coolers which have no
Die Fig. 12 zeigt ebenfalls einen "rohrbodenlosen" Kühler, der vollständig, also einschließlich der Sammelkästen 5, aus Aluminium hergestellt ist. Im Unterschied zu dem in den Fig. 9 bis 11 beschriebenen Kühler, wurde in Fig. 12 der Anschlußstutzen 12 in direkter Nachbarschaft zum ersten Flachrohr 8.1 angeordnet. Die übrige Ausbildung kann identisch mit der beschriebenen sein. Die zeichnerische Darstellung in Fig. 12 enthält auch die Verbindungsränder 20, die ein Teil des ansonsten nicht gezeigten Sammelkastens 5 sind.Fig. 12 also shows a "tube bottomless" radiator, which is completely, that is, including the
