Description

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Kühlern, die Sammelkästen mit Rohrböden aufweisen, wie in Fig. 4 der erwähnten Anmeldung gezeigt ist.Said previously unpublished cooler assembly consists of coolers having headers with tube plates, as shown in Fig. 4 of the aforementioned application.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 claim 1. Claims 2 to 9 describe variants and developments of the cooler arrangement.

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 claim 1 is provided, a radiator assembly with connected to the collection box inlet and outlet lines for fluidic connection of several cooler, being arranged in direct or indirect proximity to the end of the first and / or last flat tube of the at least one flat tube - row a connecting piece whose mouth in the Collection box is provided in a row with the mouths of the flat tubes in the collection box and the connection of the inflow or outflow of the

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 (claims 2 and 3) or at least some of the coolers can also according to the applications DE 100 16 113 8, DE 100 19 268.8 or DE 100 33 070.3 be formed without tube bottom, (claims 4 and 5). These applications are expressly incorporated by reference. Features not mentioned here which may be required for feasibility are contained in the latter applications.

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.

Die Erfindung wird nachfolgend in einigen Ausführungsbeispielen beschrieben, wozu auf die beiliegenden Zeichnungen Bezug genommen wird. Daraus können gegebenenfalls weitere Merkmale und Wirkungen der Erfindung entnommen werden.The invention will be described below in some embodiments, reference being made to the accompanying drawings.

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 upper radiator 1 and the lower radiator 2 of the radiator arrangement can be seen, and a centrifugal fan 10 enclosed by the radiator arrangement with a fan axis V. The radiator arrangement has a front wall F and a rear wall R. The flat tubes 8 of all radiators 1, 2, 6 extend transversely to the fan axis V. They were drawn in Fig. 1 only in the upper radiator. On the rear wall R are inflow 3z and on the front wall F drain lines 3a. The coolers 2, 6 and 7 are cooling liquid coolers which are connected by means of the inflow and outflow lines 3z and 3a . The radiator 7 is arranged opposite to the radiator 6 , as can be understood from FIG. 1 to 5 arrows 4 were drawn, which indicate the flow direction of the lines 3z, 3a and the radiator 2, 6, 7 in the flat tubes 8, not shown. The flat tubes 8 extend thus in the direction of the illustrated in FIGS. 2, 3 and 5 in the coolers 2 or 6 arrows 4, and thus transverse to in Fig. 1 plotted Vertilatorachse V. The Einritt the cooling liquid is arranged at the rear wall R at the corner portion e. (FIG. 4) The outlet is located in the diagonal corner region E on the front wall F. (FIG. 3) As can be seen, for example, from FIG. 2, the radiators 1, 2, 6 and 7 each have two header tanks 5, each two headers 5 adjacent radiator 2, 6 form an edge of the radiator assembly, where they are close to each other to complete the radiator assembly and thereby force the sucked by the radial fan 10 cooling air to flow through between the flat tubes 8 of the radiator. From Figs. 2 and 4, the adjacent collecting tanks 5 can be seen.

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 inflow ducts 3z and the outflow ducts 3a consist of straight duct sections 23, bent duct sections 26, elbows 24 and crosspieces 25 connected by connecting sleeves 13 . They can be plugged together using gaskets. The straight and bent pipe sections 23; 26 are made of extruded aluminum profiles. The manifold 24 and the cross pieces 25 are molded plastic parts. With such a configuration, any circuit variants, ie fluidic connections of several coolers, can be realized cost-effectively.

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 outlet lines 3z and 3a were now connected in a very special way to the manifolds 5 , whereby the radiator assembly but also each individual radiator receives a very compact and space-saving design. The circled in FIGS. 1 to 5 ports A are shown in more detail in FIGS. 6 to 12 in several variants and will be described below. As the above figures show, only the port A has been shown to each of the individual coolers 2, 6 or 7 , which can then be assembled to the radiator assembly as described above. FIGS. 6 to 8 illustrate a variant in which coolers 2, 6, 7 are used, which have opposite tubesheets 11 , of which only one is shown. The tubesheets 11 have a number of openings in a known manner, in which the ends of the flat tubes 8 open, they form orifices 22. Furthermore, the tubesheets 11 a supernatant 17, ie they go well over the first or last flat tube 8.1 of the flat tube row out. The supernatant 17 is covered by the end of the collecting tank 5 , as shown in FIG. 6. In the supernatant 17 there is an opening 15 in which the end of a connecting piece 12 fits into and thereby forms the mouth 21 . The opening 15 has a passage 18, comparable to the passages 18 at the openings provided for the flat tubes 8 , which form the orifices 22 . In the embodiment, the passages 18 have been mounted or directed inward. In other embodiments, not shown, the passages 18 for out of the flat tubes 8 and the corrugated fins 9 cooling network out, so to the outside. From Fig. 6, in particular the indirect neighborhood in this case between the connecting piece 12 and the last flat tube 8.1 of the flat tube row can be seen. Indirectly, the neighborhood is because the cooler has a side part 16 and an outer corrugated fin 9 , which are arranged between the connecting piece 12 and the flat tube 8.1 . As shown in particular Figures 7 and 8 make clear, the mouth 21 of the connecting piece 12 in a row with the mouths 22 of the flat tubes 8; 8.1 has been arranged. The cross section of the connecting piece 12, in the region of its mouth 21, is approximately rectangular in shape in this embodiment. However, it can be arbitrarily, for example, also be formed round, of course, the opening in the tube sheet 11 must have the same shape. The connecting piece 12 also has at the opposite end of the mouth 21 a connecting sleeve 13, the connection of the supply or discharge line 3z; 3a serves as already explained above. The headers 5 can z. B. made of aluminum, in which case the connection edges 20 of the manifolds 5 can be connected to the tube sheets 11 and at the same time all other items by means of soldering. However, this embodiment also allows the use of collecting tanks 5 made of plastic, in which case the connecting edges 20 must be mechanically and tightly connected to the tube sheets 11 in a known manner.

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 tubesheets 11 . First, the variant of FIGS. 9 to 11 will be described. The ends 30 of the flat tubes 8; 8.1 have bends in such a way that the ends 30 abut each other with the longitudinal sides 31 of adjacent flat tubes 8 and can be connected by means of soldering. In indirect proximity to the first flat tube 8.1 of the connecting piece 12 is arranged. In between is the end of a corrugated fin 9 and a side part 16. The mouths 22 of the flat tubes 8; 8.1 and the Mouth 21 of the connecting piece 12 are also in this case in a row, as shown in FIGS. 10 and 11 can be seen. The mouth 21 of the connecting piece 12 has been shaped approximately rectangular. After the flat tubes 8; 8.1, the corrugated fins 9 and the connecting piece 12 have been joined , the collecting box 5 shown in Figure 9 partially attached, in such a way that its connecting edges 20, the ends 30 of the flat tubes 8; 8.1 at the narrow sides 32 and the end of the connecting piece 12 include. Since the entire radiator of this embodiment is made of aluminum, all connections can be made with a soldering operation. As can be seen from the above description, this variant is therefore particularly suitable for coolers made entirely of aluminum.

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 manifolds 5, made of aluminum. In contrast to the cooler described in FIGS. 9 to 11, the connection piece 12 was arranged in the direct vicinity of the first flat tube 8.1 in FIG. The rest of the training may be identical to that described. The drawing in Fig. 12 also includes the connection edges 20, which are part of the collection box 5, which is not otherwise shown.
