- the prior art uses a welded tube with turbulence insert. This pipe is more expensive than an extruded profile and difficult to solder fluxless.
- an extruded profile 200 is used with fluid-tight inner channels 210, as for example, as a sectional view in Fig. 2c is shown.
- the extruded profile is designed, for example, so that at the 2 outer chambers 214, the distance between the tube wall 216 and the first (outermost) vertical web 218 is greater than in the inner chambers 220 (ie, the chambers or channels 220, the farther from Pipe end 212 or a pipe side wall are away as the outer chambers 214.

- the bore 222 is designed so that the two outer channels 214 are open to bore 222 back. In this way it can be achieved that on the one hand good cooling of a large amount of fluid through the outer channels 214 is enabled. On the other hand, it can also be ensured at the same time that no excessive friction loss occurs in these outer channels 214 due to the further outer channels 214, which causes uneven flow behavior in old inner channels 210 and thus causes undesired pressure fluctuations in the heat exchanger 1.
- the bore 222 can be replaced by an opening 224 towards the tube end (which, however, has a small amount of strength.)
- An embodiment of such an opening 224 in a tube 200 is shown in FIG Fig. 2f shown in isometric view.
- the outer channels 214 must be opened when between the pipe end and bending edge 48 of the boot 11-17 and 21-27 a distribution channel, as will be described in more detail below.

- the two halves 44, 45 of the Einsteckschuhs 41 are pivotable about the bending line 48.
- the two halves 44, 45 are arranged at an angle of 90 degrees to each other.
- the two halves 44, 45 are opposite to in the Fig. 3 to Fig.5 illustrated unfolded position in which the two halves 44, 45 are arranged in a plane, each pivoted by 45 degrees.
- the recessed edge regions 51, 52 of the two halves 44, 45 abut each other.
- the raised areas 55, 56 are then turned away from each other.

- Fig. 10 shows a plan view of a pipe-plug connection, wherein the tube has a circular opening. It is from the Fig. 10 it can be seen that the central through-hole in the plug-in shoe 61, 62 is concentric with the bore 222 in the extruded profile 200, wherein in this embodiment the bore 222 has a circular shape. Consequently, therefore, the cup and the cup opening of the plug shoe 41 is arranged concentrically to this bore 222.

Diese Aufgabe wird durch einen Wärmetauscher gemäß Anspruch 1 gelöst.This object is achieved by a heat exchanger according to
Die vorliegende Erfindung schafft einen Wärmetauscher, insbesondere für ein Kraftfahrzeug, mit mehreren aufeinander gestapelten und miteinander verbundenen Leitungseinrichtungen, insbesondere Flachrohren, die an ihren Enden je ein Durchgangsloch zum Zuführen oder Abführen eines Mediums aufweisen, wobei die Leitungseinrichtungsenden je in einem Steckschuh aufgenommen sind und wobei die Leitungseinrichtungen je aus einem einstückig hergestellten Strangpressprofil-Element mit fluiddichten Innenkanälen gefertigt sind, wobei sich das Durchgangsloch über eine Stirnkante zumindest einer Leitungseinrichtung hinaus erstreckt, wobei ein Leitungseinrichtungsende der einen Leitungseinrichtung derart von dem Steckschuh aufgenommen ist, dass mit Hilfe des Steckschuhs ein Fluid-durchlässiger Verteilkanal von dem Durchgangsloch über die Stirnseite der Leitungseinrichtung zu einem Innenkanal an einer Außenwand der Leitungseinrichtung ausgebildet ist. Eine derartige Ausführungsform der vorliegenden Erfindung bietet den Vorteil, dass auch eine Seitenfläche des Sleckschuhs als Wärmeaustauschfläche effektiv verwendet werden kann. Hierdurch kann eine Vergrößerung der zur Verfügung stehenden Wärmeaustauschfläche ermöglicht werden, die eine noch bessere Kühlungseigenschaft eines derart ausgestalteten Wärmetauschers bietet.The present invention provides a heat exchanger, in particular for a motor vehicle, with a plurality of stacked and interconnected conduit means, in particular flat tubes, each having a through hole for feeding or discharging a medium at their ends, wherein the conduit ends are each received in a plug shoe and wherein the conduit means are each made of an integrally produced extruded profile element with fluid-tight inner channels, wherein the through hole extends beyond an end edge of at least one conduit means, a Leitungsseinrichtungsende of a conduit means is received by the plug shoe so that with the help of the plug shoe, a fluid permeable distribution channel is formed from the through hole on the end face of the conduit means to an inner channel on an outer wall of the conduit means. Such an embodiment of the present invention offers the advantage that also a side surface of the sleeve shoe can be used effectively as a heat exchange surface. In this way, an enlargement of the available heat exchange surface can be made possible, which offers an even better cooling property of a heat exchanger designed in this way.
Der vorliegenden Erfindung liegt die Erkenntnis zu Grunde, dass ein kostengünstig und einfach zu produzierende und zugleich wirksam arbeitender Wärmetauscher dann hergestellt werden kann, wenn für die Leitungseinrichtung ein Strangpressprofil-Element mit fluiddichten Innenkanälen verwendet wird. Hierdurch kann ein Normbauteil vorteilhaft für die Leitungseinrichtungen des Wärmetauschers verwendet werden. Dies wiederum erspart das arbeitsaufwändige Verschweißen eines Rohres mit einer Turbulenzeinlage oder das Verbinden eines Profils mit einem Deckel und einen Boden. Zugleich verspricht die Kombination des Steckschuhprinzips mit einem Strangpressprofil eine flexible und kostengünstige Lösung für direkte Wärmeübertrager wie Öl/Luft-Kühler oder Kühlmittelkühler.The present invention is based on the finding that a cost-effective and easy-to-produce and simultaneously effective heat exchanger can be produced if an extruded profile element with fluid-tight inner channels is used for the conduit device. As a result, a standard component can advantageously be used for the conduit devices of the heat exchanger. This, in turn, eliminates the laborious welding of a tube with a turbulence insert or the joining of a profile to a lid and a bottom. At the same time, the combination of the slip-on principle with an extruded profile promises a flexible and cost-effective solution for direct heat exchangers such as oil / air coolers or coolant coolers.
Gemäß einer günstigen Ausführungsform der Erfindung kann zumindest ein an einer Außenkante einer Leitungseinrichtung angeordneter Innenkanal eine größere Querschnittsfläche aufweisen als ein in einem Mittelbereich der Leitungseinrichtung angeordneter Innenkanal. Eine derartige Ausführungsform der vorliegenden Erfindung bietet den Vorteil, dass die Seitenwände der Leitungseinrichtung, insbesondere wenn diese als Flachrohr ausgebildet ist, zusätzlich zur Kühlung genutzt werden. In diesem Fall kann eine größere Menge an Kühlmittel durch diese Innenkanäle an der Außenkante der Leitungseinrichtung geführt werden, so dass eine effektivere Kühlung der Gesamtmenge des Kühlmittels erreicht werden kann.According to a favorable embodiment of the invention, at least one arranged on an outer edge of a conduit means inner channel have a larger cross-sectional area than a arranged in a central region of the conduit means inner channel. Such an embodiment of the present invention has the advantage that the side walls of the conduit device, in particular if this is designed as a flat tube, are used in addition to the cooling. In this case, a larger amount of coolant can be passed through these inner channels at the outer edge of the conduit means, so that a more effective cooling of the total amount of the coolant can be achieved.
Auch kann gemäß einer weiteren Ausführungsform der Erfindung bei zumindest einem an einer Außenkante der Leitungseinrichtung angeordneten Innenkanal ein Abstand zwischen einer Innenrohrwand und einem von der Innenrohrwand benachbarten Steg größer sein, als bei einem Innenkanal, der in dem Mittelbereich der Leitungseinrichtung angeordnet ist. Eine derartige Ausführungsform der vorliegenden Erfindung bietet den Vorteil, dass in einem Innenkanal an einer Außenkante der Leitungseinrichtung ein Bereich mit einer größeren Querschnittfläche vorhanden ist, so dass ein ansonsten Druckabfall durch einen Reibungsverlust beim Strömen eines Fluids durch diesen breiteren Innenkanal ausgeglichen oder verhindert werden kann.Also, according to a further embodiment of the invention, in at least one inner channel disposed on an outer edge of the conduit means, a distance between an inner tube wall and a land adjacent the inner tube wall may be greater than with an inner channel disposed in the central region of the conduit means. Such an embodiment of the present invention offers the advantage that an area with a larger cross-sectional area is present in an inner channel at an outer edge of the conduit means, so that an otherwise pressure drop can be compensated for or prevented by a friction loss as a fluid flows through this wider inner channel.
Gemäß einer weiteren Ausführungsform der Erfindung kann die Innenseite zumindest eines Innenkanals eine gerippte Form ausweisen, derart, dass sich in dem Innenkanal mindestens ein Steg von der Wand des Innenkanals in Richtung der Mitte des Innenkanals hin erstreckt. Eine derartige Ausführungsform der vorliegenden Erfindung bietet den Vorteil, dass sich durch den in Richtung der Mitte des Innenkanals hin erstreckten Steg eine große Wärmeübertragungsfläche in diesem Innenkanal ausgebildet werden kann, so dass eine effektive kühlung durch den Wärmetauscher möglich wird.According to a further embodiment of the invention, the inside of at least one inner channel may have a ribbed shape, such that at least one web extends in the inner channel from the wall of the inner channel in the direction of the center of the inner channel. Such an embodiment of the present invention offers the advantage that a large heat transfer surface can be formed in this inner channel through the web extending in the direction of the center of the inner channel, so that effective cooling by the heat exchanger becomes possible.
Weiterhin kann auch zumindest einer der Innenkanäle der Leitungseinrichtungen zumindest teilweise eine H-Form aufweisen. Eine derartige Form eines Innenkanals weist eine besonders gute Wärmeübertragungseigenschaft auf da beispielsweise gegenüber einem zylindrischen Innenkanal eine sehr große Flächen von Innenwänden eines solchen Innenkanals zur Übertragung von Wärme zur Verfügung steht.Furthermore, at least one of the inner channels of the conduit means may also have at least partially an H-shape. Such a shape of an inner channel has a particularly good heat transfer property since, for example, compared with a cylindrical inner channel, a very large area of inner walls of such an inner channel is available for the transfer of heat.
Gemäß einer anderen Ausführungsform der Erfindung können alle Innenkanäle zum Durchgangsloch hin geöffnet sein. Eine derartige Ausführungsform der vorliegenden Erfindung bietet den Vorteil, dass hierdurch eine besonders gleichmäßige Versorgung der Innenkanäle mit dem durch das Durchgangsloch in die Leitungseinrichtung geführte Fluid gewährleistet ist.According to another embodiment of the invention, all the inner channels may be open to the through hole. Such an embodiment of the present invention has the advantage that in this way a particularly uniform supply of the inner channels is ensured with the guided through the through hole in the conduit means fluid.

Das Flachrohr 3 kann auch durch eine Grundplatte ersetzt werden, die den Kühler 1 nach unten abschließt. Ebenso kann das Flachrohr 9 durch eine Abdeckplatte ersetzt werden, die den Kühler 1 nach oben abschließt. Die Flachrohre 3 bis 9 weisen an ihren Enden jeweils mindestens eine Öffnung auf, durch die ein zu kühlendes Medium, insbesondere ein Kühlmittel, ein- beziehungsweise austreten kann. Die Flachrohre 3 bis 9 werden in Längsrichtung von dem zu kühlenden Medium durchströmt. An der Außenseite werden die Flachrohre 3 bis 9 mit einem anderen Kühlmittel, beispielsweise mit Luft, beaufschlagt, das beziehungsweise die die Flachrohre 3 bis 9 senkrecht zur Zeichenebene in
Im Stand der Technik wird ein geschweißtes Rohr mit Turbulenzeinlage verwendet. Dieses Rohr ist teurer als ein Strangpressprofil und nur schwer flussmittelfrei zu löten.The prior art uses a welded tube with turbulence insert. This pipe is more expensive than an extruded profile and difficult to solder fluxless.
Um diesen Nachteil zu vermeiden, wird ein Strangpressprofil 200 mit fluiddichten Innenkanälen 210 verwendet, wie es beispielsweise als Schnittdarstellung in
Die Bohrung 222 wird so ausgeführt, dass auch die zwei äußeren Kanäle 214 zu Bohrung 222 hin geöffnet sind. Auf diese Weise kann erreicht werden, dass einerseits eine gute Kühlung einer großen Fluidmenge über die äußeren Kanäle 214 ermöglicht wird. Andererseits kann zugleich auch sichergestellt werden, dass durch die weiteren äußeren Kanäle 214 kein zu großer Reibungsverlust in diesen äußeren Kanälen 214 entsteht, der ein ungleichmäßiges Strömungsverhalten in alten Innenkanälen 210 verursacht und damit ungewünschte Druckschwankungen im Wärmetauscher 1 bewirkt.The

Zusammenfassend ist somit anzumerken, dass ein in dieser Beschreibung ein direkter Wärmeübertrager aus Strangpressprofilen und Steckschuhen vorgestellt ist. Dabei wird im Stand der Technik ein Öl-Luft Kühler mit Steckschuhen beschrieben, wobei die im Folgenden beschriebenen konstruktiven Maßnahmen den schon bekannten Kühler durch die Verwendung von Strangpressprofilen wesentlich vereinfachen. Desweitern ist der hier vorgestellte Kühlertyp nicht nur für die Ölkühlung sondern auch für die Kühlmittelkühlung denkbar.In summary, it should therefore be noted that in this description, a direct heat exchanger of extruded profiles and plug-in shoes is presented. In this case, an oil-air cooler is described with plug-in shoes in the prior art, the constructive measures described below significantly simplify the already known cooler by the use of extruded profiles. Furthermore, the cooler type presented here is conceivable not only for oil cooling but also for coolant cooling.
