Description

Die Erfindung betrifft einen Kondensator für eine Klimaanlage, insbesondere eines Kraftfahrzeugs, mit einen Rohr- Rippenblock bildenden Rohren und Rippen, die von einem Fluid durchströmbar sind, mit beiderseits des Rohr-Rippenblocks angeordneten Sammelrohren, die die Enden der Rohre aufnehmen, und mit mindestens einem parallel zu einem der Sammelrohre angeordneten Sammler, der über Öffnungen mit dem benachbarten Sammelrohr in Fluidverbindung steht, eine Trockner- und/oder Filterpatrone aufnimmt, die im Sammler befestigt ist und an mindestens einer Stirnseite eine Kopplungsvorrichtung aufweist, die ein Verschlussteil zum fluiddichten Schließen des Sammlers und ein Brückenteil zum aneinander Festlegen von Sammler und Sammelrohr umfasst, wobei das Brückenteil eine erste Halteeinrichtung aufweist mit der es am Sammelrohr festlegbar ist sowie ein Verfahren zur Herstellung eines solchen Kondensators.The invention relates to a condenser for an air conditioning system, in particular of a motor vehicle, with tubes forming a tube-fin block and ribs through which fluid can pass, collecting tubes arranged on both sides of the tube-rib block, which receive the ends of the tubes, and at least one a collector arranged in parallel with one of the headers, which is in fluid communication via openings with the adjacent header, accommodates a dryer and / or filter cartridge which is mounted in the header and at least one front side has a coupling device comprising a closure member for fluid-tight closing of the header and a bridge part for securing collector and collector together, wherein the bridge part has a first holding device with which it can be fixed to the collector pipe and a method for producing such a capacitor.

Ein gattungsgemäßer Kondensator ist bekannt aus DE 103 06 192 A1 . Die Kopplungsvorrichtung besteht aus einem einzigen Teil an dem das Verschlussteil und das Brückenteil ausgebildet sind. Das Verschlussteil wird stirnseitig mit dem Sammler verlötet, um diesen fluiddicht zu schließen. Das Brückenteil ist fest und unbeweglich mit dem Verschlussteil verbunden. Hierdurch ist ein Verlöten von Sammler und Verschlussteil ausschließlich von Innen möglich. Dies erweist sich in der Fertigung als umständlich und kostenintensiv.A generic capacitor is known from DE 103 06 192 A1 , The coupling device consists of a single part on which the closure part and the bridge part are formed. The closure part is soldered on the front side with the collector in order to close it fluid-tight. The bridge part is firmly and immovably connected to the closure part. As a result, a soldering of collector and closure part is possible only from the inside. This proves to be cumbersome and costly in production.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Kondensator vorzuschlagen, der einfach zu fertigen sowie kostengünstig herzustellen ist.The present invention has for its object to provide a capacitor which is easy to manufacture and inexpensive to manufacture.

Die Aufgabe wird durch einen erfindungsgemäßen Kondensator gelöst, bei dem das Verschlussteil und das Brückenteil separate Teile umfassen, die mittels einer zweiten Halteeinrichtung miteinander verbunden sind. Grundsätzlich ist es denkbar, dass das Brückenteil unbeweglich mit dem Verschlussteil verbunden ist. Es ist jedoch bevorzugt, wenn das Brückenteil um die zweite Halteeinrichtung zumindest in einem Winkelbereich drehbar ist. Hierdurch kann das Brückenteil verschoben werden, wenn das Verschlussteil mit dem Sammler verlötet wird. Darüber hinaus kann das Verschlussteil mit dem Sammler verlötet werden, bevor das Brückenteil und das Verschlussteil miteinander verbunden werden. In beiden Fällen ist ein Verlöten von Sammler und Verschlussteil von Außen ermöglicht, was die Fertigung vereinfacht.The object is achieved by a capacitor according to the invention, in which the closure part and the bridge part comprise separate parts which are interconnected by means of a second holding device. In principle, it is conceivable that the bridge part is immovably connected to the closure part. However, it is preferred if the bridge part is rotatable about the second holding device at least in an angular range. As a result, the bridge part can be moved when the closure part is soldered to the collector. In addition, the closure member can be soldered to the collector before the bridge member and the closure member are joined together. In both cases it is possible to solder the collector and the closure part from the outside, which simplifies the production.

Grundsätzlich ist es denkbar, dass das Verschlussteil und das Brückenteil lösbar miteinander verbunden sind. Allerdings wird bevorzugt, wenn das Verschlussteil und das Brückenteil mittels der zweiten Halteeinrichtung unlösbar miteinander verbunden sind, insbesondere miteinander verstemmt sind. Hierdurch wird eine nietenartige Verbindung von Verschlussteil und Brückenteil erreicht.In principle, it is conceivable that the closure part and the bridge part are releasably connected to each other. However, it is preferred if the closure part and the bridge part are inseparably connected to one another by means of the second holding device, in particular are caulked to one another. As a result, a rivet-like connection of the closure part and the bridge part is achieved.

Es erweist sich als vorteilhaft, wenn die zweite Halteeinrichtung durch eine pilzartige Erhebung am Verschlussteil, die einen Halsabschnitt und einen Kopfabschnitt aufweist, und durch eine komplementär zum Halsabschnitt der pilzartigen Erhebung ausgebildeten Öffnung im Brückenteil gebildet ist. Der Halsabschnitt der pilzartigen Erhebung weist bevorzugt einen kreisförmigen Querschnitt auf, wodurch das Brückenteil um den Halsabschnitt der pilzartigen Erhebung des Verschlussteils verdreht werden kann, wenn das Brückenteil und das Verschlussteil miteinander verbunden sind.It proves to be advantageous if the second holding device is formed by a mushroom-like elevation on the closure part, which has a neck portion and a head portion, and by a complementary to the neck portion of the mushroom-like elevation opening formed in the bridge portion. The neck portion of the mushroom-shaped protrusion preferably has a circular cross-section, whereby the bridge part can be rotated about the neck portion of the mushroom-like protrusion of the closure part when the bridge part and the closure part are connected to each other.

In Weiterbildung der Erfindung ist der Kopfabschnitt der pilzartigen Erhebung am Verschlussteil durch ein Verstemmen des freien Endes des Halsabschnitts der Erhebung gebildet.In a further development of the invention, the head portion of the mushroom-like elevation is formed on the closure part by caulking the free end of the neck portion of the elevation.

Darüber hinaus erweist es sich als vorteilhaft, wenn das Verschlussteil und/oder das Brückenteil jeweils ein Stanzteil umfasst. Solchenfalls sind Verschlussteil und Brückenteil kostengünstig herstellbar.In addition, it proves to be advantageous if the closure part and / or the bridge part in each case comprises a stamped part. In this case, closure part and bridge part are inexpensive to produce.

Ferner erweist es sich als vorteilhaft, wenn das Verschlussteil scheibenförmig ist und einen angeformten Rand aufweist. Durch den angeformten Rand ist eine Vormontage des Verschlussteils mit dem Sammler, beispielsweise durch eine Presspassung, ermöglicht. Bevorzugt weist der Rand des Verschlussteils eine Riffelung auf und ist insbesondere sternförmig angeformt.Furthermore, it proves to be advantageous if the closure part is disk-shaped and has an integrally formed edge. Due to the molded edge, a pre-assembly of the closure part with the collector, for example by a press fit, allows. Preferably, the edge of the closure part has a corrugation and is formed in particular star-shaped.

In Weiterbildung der Erfindung weist das Verschlussteil auf der dem Sammler abgewandten Seite einen Randbereich und einen bezüglich des Randbereichs zurückspringenden Bereich auf, an dem die pilzartige Erhebung angeordnet ist. Hierdurch kann der Kondensator in Längsrichtung kompakt ausgebildet werden.In a further development of the invention, the closure part on the side facing away from the collector on an edge region and a recessed area with respect to the edge region on which the mushroom-like elevation is arranged. As a result, the capacitor can be made compact in the longitudinal direction.

Darüber hinaus erweist es sich in Weiterbildung letztgenannten Erfindungsgedankens als vorteilhaft, wenn das Brückenteil einen mehrfach gebogenen Abschnitt aufweist, mit dem es einerseits zumindest teilweise am zurückspringenden Bereich des Verschlussteils und andererseits am Randbereich des Verschlussteils oder des stirnseitigen Rands des Sammlers anliegt. Hierdurch bildet das Brückenteil einen Anschlag für das Sammelrohr, was das Ausrichten von Sammler und Sammelrohr vereinfacht.In addition, it proves to be advantageous in a further development of the invention, if the bridge part has a multiply bent portion, with which it rests at least partially on the recessed portion of the closure part and on the other hand at the edge region of the closure part or the front edge of the collector. As a result, the bridge part forms a stop for the manifold, which simplifies the alignment of collector and manifold.

Weiter weist bei einem erfindungsgemäßen Ausführungsbeispiel das Verschlussteil eine Lötplatierung und/oder ein Fluxmittel auf.Furthermore, in an embodiment according to the invention, the closure part has a soldering plating and / or a fluxing agent.

Zur Lösung der Aufgabe wird schließlich ein Verfahren zum Herstellen eines Kondensators nach einem der vorhergehenden Ansprüche vorgeschlagen, bei dem das Verschlussteil und/oder das Brückenteil gestanzt werden, ggf. das Verschlussteil und/oder das Brückenteil gepresst und/oder gebogen werden, das Verschlussteil und das Brückenteil mittels der zweiten Halteeinrichtung miteinander verbunden werden und schließlich der Sammler mit dem Verschlussteil fluiddicht verschlossen wird.To achieve the object, finally, a method for producing a capacitor according to one of the preceding claims is proposed, in which the closure part and / or the bridge part are punched, possibly the closure part and / or the bridge part pressed and / or bent, the closure part and the bridge part are connected to each other by means of the second holding device and finally the collector is sealed fluid-tight with the closure part.

Hierbei sind die einzelnen Verfahrensschritte in ihrer Reihenfolge beliebig. Beispielsweise kann das fluiddichte Verschließen des Sammlers durch das Verschlussteil vor dem Verbinden des Verschlussteils mit dem Brückenteil erfolgen.Here, the individual process steps in their order are arbitrary. By way of example, the fluid-tight closing of the collector by the closure part can take place before the closure part is connected to the bridge part.

Die Figuren zeigen einen Bereich eines insgesamt mit dem Bezugszeichen 2 versehenen Kondensators. Der Kondensator 2 umfasst einen aus Rohren und Rippen gebildeten Rohr- Rippenblock (nicht dargestellt), deren Enden in Öffnungen 4 eines Sammelrohrs 6 eingesteckt und mit diesem fluidverbunden sind. Parallel zum Sammelrohr 6 ist ein hohlzylindrischer Sammler 8 angeordnet, der in seinem Inneren eine Trockner- und/oder Filterpatrone aufnimmt (nicht dargestellt) und mit dem Sammelrohr 6 fluidverbunden ist.The figures show a portion of a capacitor generally designated by the reference numeral 2. The condenser 2 comprises a tube-fin block (not shown) formed from tubes and ribs, the ends of which are inserted into openings 4 of a collecting tube 6 and are fluid-connected thereto. Parallel to the manifold 6, a hollow cylindrical collector 8 is arranged, which receives in its interior a dryer and / or filter cartridge (not shown) and is fluidly connected to the manifold 6.

Der Sammler ist stirnseitig mit einem scheibenförmigen Verschlussteil 10 einer Kopplungsvorrichtung 12 fluiddicht verschlossen. Das Verschlussteil 10 hat einen sternförmig angeformten Rand 14, der eine Presspassung des Verschlussteils 10 mit dem Sammler 8 beim Montieren ermöglicht.The collector is closed at the end face with a disk-shaped closure part 10 of a coupling device 12 in a fluid-tight manner. The closure member 10 has a star-shaped edge 14 which allows a press fit of the closure member 10 with the collector 8 during mounting.

Das Verschlussteil 10 hat auf seiner dem Sammler 8 abgewandten Seite einen Randbereich 16 und einen in Richtung auf den Sammler 8 zurückspringenden Bereich 18. Am zurückspringenden Bereich 18 des Verschlussteils 10 ist eine pilzartige Erhebung 20 mit einem Halsabschnitt und einem Kopfabschnitt angeordnet.The closure part 10 has on its side facing away from the collector 8 an edge region 16 and a recessed area in the direction of the collector 8 area 18. At the recessed portion 18 of the closure part 10 is a mushroom-like elevation 20 is arranged with a neck portion and a head portion.

Die pilzartige Erhebung 20 bildet zusammen mit einer komplementär zum Halsabschnitt der pilzartigen Erhebung 20 ausgebildeten Öffnung 22 in einem Brückenteil 24 der Kopplungsvorrichtung 12 eine zweite Halteeinrichtung 26. Auf der der Öffnung 22 gegenüberliegenden Seite des Brückenteils 24 ist eine erste Halteeinrichtung 28 angeordnet, mit der das BrUckenteil 24 mit dem Sammelrohr 6 verbindbar ist.The mushroom-like elevation 20, together with a complementary to the neck portion of the mushroom-like elevation 20 formed opening 22 in a bridge portion 24 of the coupling device 12, a second holding device 26. On the opposite side of the opening 22 of the bridge portion 24, a first holding device 28 is arranged, with the Brück part 24 with the manifold 6 is connectable.

Das Brückenteil 24 hat im Bereich der zweiten Halteeinrichtung 28 einen mehrfach gebogenen Abschnitt 30, mit dem es einerseits am zurückspringen Bereich 18 des Verschlussteils 10 und bei dem gezeigten Ausführungsbeispiel am stirnseitigen Rand des Sammlers 8 anliegt und einen Anschlag für das Sammelrohr 6 bildet.The bridge part 24 has in the region of the second holding device 28 a multiply bent portion 30, with which it rests on the one hand on the recessed portion 18 of the closure member 10 and in the embodiment shown at the front edge of the collector 8 and forms a stop for the manifold 6.

Im Folgenden wird auf das Fügen der einzelnen Komponenten des Kondensators 2 näher eingegangen.In the following, the joining of the individual components of the capacitor 2 is discussed in greater detail.

Die Kopplungsvorrichtung 12 wird aus dem Verschlussteil 10 und dem Brückenteil 24 gebildet. Hierzu wird das Brückenteil 24 so auf das Verschlussteil 10 aufgesetzt, dass die Erhebung 20 durch die Öffnung 22 des Brückenteils 24 hindurch ragt. Nachfolgend wird die Erhebung verformt, so dass ein Halsbereich und ein Kopfbereich gebildet werden. Der Kopfbereich hat einen größeren Durchmesser als die Öffnung 22 des Brückenteils 24 und hintergreift hierdurch das Brückenteil 24. Hierdurch ist ein nietenartiges Festlegen beider Teile gegeben.The coupling device 12 is formed from the closure part 10 and the bridge part 24. For this purpose, the bridge part 24 is placed on the closure part 10 so that the elevation 20 projects through the opening 22 of the bridge part 24 therethrough. Subsequently, the survey is deformed, so that a neck area and a head area are formed. The head portion has a larger diameter than the opening 22 of the bridge portion 24 and thereby engages behind the bridge portion 24. This gives a rivet-like setting of both parts.

Nach dem Fügen von Verschlussteil und 10 und Brückenteil 24 wird die Kopplungsvorrichtung 12 stirnseitig auf den Sammler 8 und auf das Sammelrohr 6 aufgesetzt. Das Verschlussteil 10 der Kopplungsvorrichtung 12 wird in den Sammler eingesetzt. Mittels des sternförmig angeformten Rands 14 wird eine Presspassung mit dem Sammler 8 gebildet. Diese erleichtert das nachfolgende Verlöten von Verschlussteil 10 und Sammler 8. Mittels der ersten Halteeinrichtung 28 wird das Brückenteil 24 der Kopplungsvorrichtung 12 mit dem Sammelrohr 6 verbunden. Hierdurch werden Sammler 8 und Sammelrohr 6 einfach und kostengünstig aneinander festgelegt.After the joining of the closure part and the bridge part 24 and 10, the coupling device 12 is placed on the front side of the collector 8 and on the collecting pipe 6. The closure part 10 of the coupling device 12 is inserted into the collector. By means of the star-shaped edge 14, a press fit with the collector 8 is formed. This facilitates the subsequent soldering of closure part 10 and collector 8. By means of the first holding device 28, the bridge part 24 of the coupling device 12 is connected to the manifold 6. As a result, collector 8 and manifold 6 are easily and inexpensively fixed to each other.
