Die Erfindung featrifit r.vnen Wärmeta"2E'.her, insbesondere einen ölkühler für Kraf:fahrzeuge, bestenend aus mehreren, von einem ersten Wärmetauschmittel durchströmten Flaehrohrabschnitten, die beidseitig durch Flachquetsch« ^. "nd/oder durch einen flachgequetschten Stehfalz geschlossen sind und unter Zwischenschaltung von lamellenartigen und vom zweiten Wärmetauschmedium angeströmten Rippen parallel aneinanderliegen.The invention features a heat exchanger, in particular an oil cooler for motor vehicles , consisting of several flat tube sections through which a first heat exchange medium flows, which are closed on both sides by flat crimping and/or by a flat crimping standing seam and lie parallel to one another with the interposition of lamellar ribs against which the second heat exchange medium flows.
Wärmetauscher dieser Art sind bekannt (DE-GM 89 03 873). Der Wärmetauscher dieser bekannten Art wird dadurch hergestellt, daß ein Flachrohr zick-zack-förmig oder serpentinenartig so gebogen wird, daß die zwischen den Biegestellen verlaufenden Flachrohrabschnitte parallel zueinander liegen. Die Abdichtung der Flachrohrabschnitte, die durch quer verlaufende Bohrungen mit Anschlußstutzen für das Wärmetauschmedium versehen werden, wird durch das Flachquetschen der Rohrwandungen an den Biegestellen einerseits und an den beiden zunächst offenen Enden des Rohres durch einen flachgequetschten Stehfalz erreicht. Die Abdichtung solcher Stehfalze macht gewisse Schwierigkeiten, &uch wenn eine Verlötung vorgenommen wird.Heat exchangers of this type are known (DE-GM 89 03 873). The heat exchanger of this known type is manufactured by bending a flat tube in a zigzag or serpentine shape so that the flat tube sections running between the bending points are parallel to each other. The sealing of the flat tube sections, which are provided with connection pieces for the heat exchange medium through transverse bores, is achieved by flattening the tube walls at the bending points on the one hand and at the two initially open ends of the tube by means of a flattened standing seam. Sealing such standing seams presents certain difficulties, even when soldering is carried out.
Es ist auch bekannt, Wärmetauscher durch mehrere einzelne stapelartig aufeinander angeordnete Flachröhre zu bilden (EP 106 479 Al) , deren Enden durch zusätzlich aufgesetzte Endstücke abgedichtet werden, die mehrere jeweils parallelIt is also known to form heat exchangers by means of several individual flat tubes arranged in a stack (EP 106 479 Al), the ends of which are sealed by additional end pieces which have several parallel
zueinander und auf den Abstand der Piachrohre abgestimmte Auswölbungen in der Form von Kappen besitzen, zwischen die die offenen Endbereiche der Flachrohre hereingeschoben und dann verlötet werden. Solchermaßen hergestellte Wärmetauscher sind verhältnismäßig aufwendig.to each other and to the distance between the Piach tubes, have bulges in the form of caps, between which the open end areas of the flat tubes are pushed and then soldered. Heat exchangers manufactured in this way are relatively complex.
üer Erfindung liegt die Aufgabe zugrunde, einen Wärmetauscher der eingangs gemimten Art so auszubilden, daß der endseitige Abschluß der Flachrohre ohne großen Aufwand, aber so vorgenommen wird, daß die Dichtheit in jedem Fall gewährleistet ist.The invention is based on the object of designing a heat exchanger of the type initially described in such a way that the end closure of the flat tubes is carried out without great effort, but in such a way that the tightness is guaranteed in every case.
Zur Lösung dieser Aufgabe wird bei einem Wärmetauscher der eingangs genannten Art vorgesehen, die an den Rohrenden angeordneten Stehfalze mit einer in Längsrichtung des Falzes verlaufenden Wellenkontur zu versehen. Dies kann in einfacher Weise nach dem Umfalzen durch ein entsprechendes Preßwerkzeug geschehen, das den Stehfalz zu einer Wellenkontur druckt. Diese Ausgestaltung ergibt zum einen einen sehr stabilen Abschlußfalz. Sie gewährleistet auch wegen des in sich stabilen Falzes dessen Dichtheit, und zwar auch dann, wenn der Wärmetauscher im Betrieb, wie das beim Einsatz für Ölkühler für Kraftfahrzeuge der Fall ist, relativ starken mechanischen Belastungen ausgesetzt wird.To solve this problem, in a heat exchanger of the type mentioned above, the standing seams arranged at the pipe ends are provided with a wave contour running in the longitudinal direction of the seam. This can be done in a simple way after folding using a suitable pressing tool that presses the standing seam into a wave contour. This design results in a very stable end seam. It also ensures that the seam is leak-tight due to its inherently stable nature, even when the heat exchanger is exposed to relatively strong mechanical stress during operation, as is the case when used for oil coolers in motor vehicles.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet. Die Merkmale des Anspruches 2 bringen in Verbindung mit der Falzausbildung nach Anspruch 1 den Vorteil, daß das aufwendige Biegen eines Flachrohres entfallen kann, ohne daß jedoch der Herstelxungsaufwand durch zusätzlich angesetzte Endkappen zu groß wird oder die Gefahr des Undichtwerdens der Flachrohre besteht. Die Merkmale des Anspruches 3 erlauben die Herstellung eines einfach aufgebauten Preßwerkzeuges.Advantageous further developments of the invention are characterized in the subclaims. The features of claim 2 in conjunction with the fold design according to claim 1 bring the advantage that the complex bending of a flat tube can be omitted, without the manufacturing effort being too great due to additional end caps or the risk of the flat tubes becoming leaky. The features of claim 3 allow the production of a simply constructed pressing tool.
Die Ausgestaltung nach den Ansprüchen 4 bis 6 bringt den Vorteil rn.it sich, daß im Bereich der öffnungen, die zum VerbindenThe design according to claims 4 to 6 has the advantage that in the area of the openings used for connecting
der Flachrohre untereinander dienen, keine Verformungen oder Verwerfungen auftreten. Die Merkmale des Anspruches 7 gewährleisten einen besonders dichten Falz und die Merkmale des Unteranspruches 8 umreißen vorteilhafte Möglichkeiten, die Lage des Falzes im Hinblick auf das Flachrohr anzuordnen. the flat tubes among each other, no deformations or distortions occur. The features of claim 7 ensure a particularly tight fold and the features of subclaim 8 outline advantageous possibilities for arranging the position of the fold with respect to the flat tube.

In der Fig. 1 ist schematisch ein Wärmetauscher in seinem grundsätzlichen Aufbau angedeutet, der für den ölkühler eines Kraftfahrzeuges verwendet werden soll. Der Wärmetauscher (1) der Fig. 1 besteht aus mehreren Flachrohren (2) bestimmter Länge, die mit ihren größeren Flächen parallel zueinander angeordnet sind und im fertigen Zustand jeweils unter äwischenfügung von lamellenartigen Rippenblechen (3) aufeinandergestapelt sind. Jedes der Flachrohre (2) ist im Bereich seiner Enden mit je einer öffnung (4) versehen, durch die, wie mit dem Pfeil (5) angedeutet ist, eines der Wärmetauschmedien, beispielsweise das zu kühlende öl, über nicht gezeigte Anschlußstutzen in das Innere des Flachrohres (2) geführt werden kann, das in bekannter Weise ebenfalls mit eingelegten Turbulenzblechen (6) ausgefüllt ist. Die öffnungen (4) jedes Flachrohres (2) stehen auch untereinander über Zwischenhülsen in Verbindung, so daß ein Wärmetauschmedium im Sinn des Pfeiles (5) in alle Flachrohre eintreten und diese durch einen und die gegenüberliegenden öffnungen (4) untereinander verbindenden AustrittsstütZeü vvicuelT &idigr;6&Ggr;&igr;&agr;&5&bgr;&Ggr;&igr; &Kgr;&agr;&idigr;&idigr;&Ggr;&igr;. DüiTCii uSs AUi-CXnSnUcOTStSpCXn u£jT Flachrohre (2) und der dazwischen liegenden Rippenbleche (3) wird ein sogenannter Rippenrohrblock gebildet, der in bekannter Weise im Sinn des Pfeiles (7) quer zu den Flachrohren (2) mit dem zweiten Wärmetauschmedium, beispielsweise mit Kühlluft angeströmt werden kann.Fig. 1 shows a schematic representation of the basic structure of a heat exchanger which is to be used for the oil cooler of a motor vehicle. The heat exchanger (1) in Fig. 1 consists of several flat tubes (2) of a certain length which are arranged with their larger surfaces parallel to one another and which, in the finished state, are stacked on top of one another with lamellar ribbed plates (3) interposed between them. Each of the flat tubes (2) is provided with an opening (4) in the region of its ends through which, as indicated by the arrow (5), one of the heat exchange media, for example the oil to be cooled, can be led via connecting pieces (not shown) into the interior of the flat tube (2), which is also filled with inserted turbulence plates (6) in a known manner. The openings (4) of each flat tube (2) are also connected to one another via intermediate sleeves, so that a heat exchange medium can enter all of the flat tubes in the direction of the arrow (5) and support them through an outlet which connects the opposite openings (4) to one another . A so-called finned tube block is formed by the flat tubes (2) and the finned plates (3) located between them, which can be flowed against in a known manner in the direction of the arrow (7) transversely to the flat tubes (2) with the second heat exchange medium, for example with cooling air.
Jedes der Flachrohre (2) besteht aus einem Rohrstück, das zunächst an beiden Enden offen ist. Die Abdichtung der Enden erfolgt dadurch, daß die Wandungen der Flachrohre (2) jeweils zu einem Stehfalz (8) zusammengedrückt und umgefalzt werden, der, wie insbesondere aus Fig. 2 zu entnehmen ist, eine wellenartige Kontur aufweist. Dies kann in einfacher Weise beispielsweise dadurch erreicht werden, daß zunächst nach Fig. 3 die obere Wand (9) des Flachrohres (2) im Endbereich (9a) nachEach of the flat tubes (2) consists of a piece of pipe that is initially open at both ends. The ends are sealed by pressing the walls of the flat tubes (2) together and folding them over to form a standing seam (8) which, as can be seen in particular from Fig. 2, has a wave-like contour. This can be achieved in a simple manner, for example, by first folding the upper wall (9) of the flat tube (2) in the end region (9a) according to Fig. 3.

unten bis etwa in die Ebene der unteren Wand (10) durch ein Werkzeug gedrückt wird, in welches das Flachrohr eingelegt wird. Dadurch liegen die Teile (10b und 9b) der Wandungen (10 und 9) zunächst parallel aufeinander. Sie werden dann zu dem Stehfalz (11) umgefaltet, der zunächst noch flach ist, aber die vierfache Stärke der Dicke der Wandungen (9 und 10) aufweist. Der Stehfalz (11) wird dann in einem Drlickwerkzeug, das die Wellenkontur der Darstellung der Fig. 2 aufweist, so zusammen-down to approximately the level of the lower wall (10) by a tool into which the flat tube is inserted. As a result, the parts (10b and 9b) of the walls (10 and 9) initially lie parallel to one another. They are then folded over to form the standing seam (11), which is initially flat but has four times the thickness of the walls (9 and 10). The standing seam (11) is then folded together in a pressing tool that has the wave contour shown in Fig. 2.
Wellenkontur erreicht, die nach unten gerichtete Scheitel (H'') und nach oben gerichtete Scheitel (11*) aufweist. Da die Wellenkontur gleichmäßig ist, sind alle Scheitel (11· und 11") über die gesamte Länge des Stehfalzes (11) gesehen, jeweils im gleichen Abstand zueinander angeordnet. Auch die Höhe (a), die der so gebildete Stehfalz (11) einnimmt, ist Ober die Breite (b) (Fig. 1) jedes Flachrohres (2) gleich groß. In der Fig. 2 und 3 ist die Ausgestaltung dabei so vorgenommen worden, daß die Mittellinie (12) des sinusartigen Verlaufes des Stehfalzes (11) in etwa mit der Mittellängsebene (13) der Flachrohre (2) zusammenfällt.A wave contour is achieved which has downward-facing peaks (H'') and upward-facing peaks (11*). Since the wave contour is uniform, all peaks (11· and 11") are arranged at the same distance from one another over the entire length of the standing seam (11). The height (a) of the standing seam (11) thus formed is also the same as the width (b) (Fig. 1) of each flat tube (2). In Fig. 2 and 3, the design has been made such that the center line (12) of the sinusoidal course of the standing seam (11) roughly coincides with the central longitudinal plane (13) of the flat tubes (2).

Teilung) und die Höhe (a) der Wellungen (die Amplitude) im mittleren Bereich des Falzes (11) kleiner als in den Außenbereichen zu wählen. Man kann dadurch vermeiden, daß beim Zusammenquetschen des Falzes (11) in diesem mittleren Bereich, der an der Stirnseite der Flachrohre (2) vor den öffnungen (4) liegt, zu viel Material in den Falz hereingezogen wird. Der Bereich der öffnung (4), über die jedes Flachrohr mit einem benachbarten verbunden wird, unterliegt daher weniger der Gefahr, daß er verformt oder verworfen wird. Der Anschluß von Verbindungsstutzen zu benachbarten Rohren kann daher nicht beeinträchtigt werden.The pitch (a) and the height (a) of the corrugations (the amplitude) in the middle area of the fold (11) should be smaller than in the outer areas. This avoids too much material being drawn into the fold when the fold (11) is squeezed together in this middle area, which is located on the front side of the flat tubes (2) in front of the openings (4). The area of the opening (4) through which each flat tube is connected to an adjacent one is therefore less at risk of being deformed or warped. The connection of connecting pieces to adjacent tubes cannot therefore be impaired.
Die Fig. 5 bis 10 zeigen Abweichungen von einer solchen Auslegung. Figs. 5 to 10 show deviations from such a design.
So ist die Ausgestaltung bei der Ausführungsform nach den Fig. 5 und 6 so vorgenommen, daß der Stehfalz (11), dessen Kontur im übrigen jener der Fig. 2 bis 4 entspricht, im Bezug zur Mittellängsebene (13) jedes Flachrohres (2) so angeordnet ist, daß jeweils die Scheitel (H") von der MittellMngsebene (13) tangiert werden. Dadurch ragen die Scheitel (H'1) deutlich über die untere Wand (10) nach unten. Der dadurch entstehende Falz (11) wird, da er schräg nach unten gezogen ist, wie Fig. 6 zeigt, sehr stabil. Die einzelnen Schichten der übereinander gefalzten Wandungsteile (9b, 10b) liegen in allen Bereichen aneinander an. Diese Bauart kann auch dazu ausgenützt werden, daß der Stehfalz (11) zur Axialführung der Rippenbleche (3) dient.Thus, the design in the embodiment according to Fig. 5 and 6 is such that the standing seam (11), the contour of which otherwise corresponds to that of Fig. 2 to 4, is arranged in relation to the central longitudinal plane (13) of each flat tube (2) in such a way that the vertices (H") are tangent to the central longitudinal plane (13). As a result, the vertices (H' 1 ) protrude significantly downwards over the lower wall (10). The resulting fold (11) is very stable because it is drawn diagonally downwards, as shown in Fig. 6. The individual layers of the wall parts (9b, 10b) folded over one another lie against one another in all areas. This design can also be used so that the standing seam (11) serves to axially guide the ribbed sheets (3).
Die Ausführung;,form der Fig. 7 und 8 sieht vor, daß die Mittellinie (12) de^ sinusförmigen Verlaufes des Stehfalzes {11) in etwa mit der Ebene der unteren Wand (10) zusammenfällt. Dadurch ergibt sich die aus Fig. 8 ersichtliche Falzform. Die Ausführungsform der Fig. 9 und 10 wiederum sieht vor, daß der Steh falz (11) noch weiter zur Mitte hin, aber noch nicht so weit wie in den Fig. 2 und 3 verschoben ist. Hier liegt die Mittellinie (12) des sinusförmigen Verlaufes des Stehfalzes {11) etwas oberhalb der Innenfläche der unteren Wand (10). Alle gezeigten Ausführungsformen weisen den Vorteil eines sehr stabilen gewellten Stehfalzes (11) auf, der, wie jeweils den Schnittzeichnungen der Fig. 3, 4, 6, 8 und 10 entnommen werden kann, auch sehr lange und gegeneinander gebe;;sr ^ Dichtflächen aufweist, die eine gute und dauerhafte Abdichtung der Flachrohre (2) ermöglichen, insbesondere wenn anschließend noch eine Verlötung vorgenommen wird.The design of Fig. 7 and 8 provides that the center line (12) of the sinusoidal course of the standing seam (11) coincides approximately with the plane of the lower wall (10). This results in the fold shape shown in Fig. 8. The design of Fig. 9 and 10, on the other hand, provides that the standing seam (11) is shifted further towards the center, but not as far as in Fig. 2 and 3. Here the center line (12) of the sinusoidal course of the standing seam (11) lies slightly above the inner surface of the lower wall (10). All embodiments shown have the advantage of a very stable corrugated standing seam (11) which, as can be seen from the sectional drawings in Fig. 3, 4, 6, 8 and 10, also has very long and mutually spaced sealing surfaces which enable a good and permanent sealing of the flat tubes (2), in particular if soldering is subsequently carried out.
