Ein Kondensator mit vertikal verlaufenden Wärmetauscherrohren ist aus der Fig. 7 des EP 769 666 A1 bekannt. Im EP'666 sind die Sammelrohre horizontal liegend angeordnet. Der Sammler verläuft parallel zu den Wärmetauscherrohren des Kondensators und ist vertikal stehend angeordnet. Die vertikale Position des Sammlers ist bezüglich der darin stattfindenden Trennung zwischen noch gasförmigem und bereits verflüssigtem Kältemittel günstig, und sie ist deshalb am weitesten verbreitet.A condenser with vertically extending heat exchanger tubes is from the Fig. 7 of EP 769 666 A1 known. In EP'666 the headers are arranged horizontally. The collector runs parallel to the heat exchanger tubes of the condenser and is arranged vertically upright. The vertical position of the collector is favorable with respect to the separation therein between still gaseous and already liquefied refrigerant, and is therefore the most widespread.

Im EP 974 793 A2 , Fig. 1, hingegen sind die Wärmetauscherrohre horizontal und somit die Sammelrohre des dortigen Kondensators vertikal stehend angeordnet. Der Sammler befindet sich parallel zu den Wärmetauscherrohren horizontal liegend, unterhalb des Rohr - Rippen - Blocks des Kondensators. In diesem Dokument wurde im Übrigen vorgesehen, das Kältemittel im Anschluss an die Durchströmung der Stufen des Kondensators durch den Sammler strömen zu lassen, weshalb dieser Kondensator einer anderen Gattung zuzurechnen ist.in the EP 974 793 A2 . Fig. 1 on the other hand, the heat exchanger tubes are horizontal and thus the collecting tubes of the local condenser are arranged vertically standing. The collector is located horizontally parallel to the heat exchanger tubes, below the tube - fin block of the condenser. Incidentally, it has been proposed in this document to allow the refrigerant to flow through the collector following the passage of the stages of the condenser, which is why this condenser belongs to a different type.

In beiden Fällen ist der Sammler lösbar, über einen angelöteten Verbindungsblock, mit einem der Sammelrohre verbunden. Es scheint keine erfinderische Tätigkeit erforderlich zu sein, um die lösbare Verbindung in eine unlösbar, beispielsweise in eine Lötverbindung, umzugestalten.In both cases, the collector is releasably connected via a soldered connection block to one of the manifolds. There does not appear to be an inventive step required to reshape the releasable bond into a non-releasable, such as a solder joint.

Aus US 5 937 671 ist ein Flüssigkeitsbehälter an einem Kondensator bekannt. Der Flüssigkeitsbehälter weist einen Innenmantel auf. In dem vom Innenmantel umschlossenen Raum befinden sich ein Trockner und ein Filter. Die Ein - bzw. Ausströmöffnungen sind dort im Außenmantel des Sammlers bzw. des Flüssigkeitsbehälters angeordnet worden.Out US 5,937,671 a liquid container is known on a condenser. The liquid container has an inner jacket. The room enclosed by the inner shell contains a dryer and a filter. The inlet and outlet openings have been arranged there in the outer jacket of the collector or the liquid container.

Ein dem Oberbegriff entsprechender Kondensator mit Sammler und mit einer Überführungsleitung ist aus dem JP 2001-174103 bekannt. Darin wird eine vorteilhafte Lösung für Kondensatoren mit oben und unten liegenden Sammelrohren und mit vertikalen Wärmetauschrohren vorgestellt. Der Sammler hat unter anderem die Funktion, gasförmiges und flüssiges Kältemittel zu trennen sowie ein Trocknungsmittel aufzunehmen. Diese Funktion wird in der JP-Veröffentlichung vielleicht nicht so gut erfüllt, wie es gewünscht wird.A to the preamble corresponding capacitor with collector and with a transfer line is from the JP 2001-174103 known. It presents an advantageous solution for condensers with top and bottom headers and vertical heat exchanger tubes. Among other things, the collector has the function of separating gaseous and liquid refrigerants as well as a To absorb desiccant. This feature may not work as well in the JP publication as it is desired.

Der Erfinder hat sich die Aufgabe gestellt, seinen Kondensator mit Sammler und mit einer Überführungsleitung so auszubilden, dass alternative Verbindungsmöglichkeiten des Sammlers mit dem Kondensator geschaffen werden.The inventor has set itself the task of designing its condenser with a collector and with a transfer line in such a way that alternative connection possibilities of the collector to the condenser are created.

Erfindungsgemäß wurde diese Aufgabe bei einem Kondensator gemäß Oberbegriff des Anspruchs 1 mit den Merkmalen aus dessen Kennzeichen gelöst.According to the invention this object has been achieved in a capacitor according to the preamble of claim 1 with the features of its characteristics.

Es ist vorgesehen, dass der Sammler einen Innenmantel aufweist, wobei Innenmantel und Außenmantel koaxial zueinander angeordnet sind, so dass zwischen dem Innenmantel und dem Außenmantel ein Strömungskanal für das Kältemittel ausgebildet ist, wobei die eine Ein - oder Ausströmöffnung mittels der Überführungsleitung mit dem vom Innenmantel umschlossenen Raum kommuniziert und die andere Ein - oder Ausströmöffnung im Außenmantel angeordnet ist.It is envisaged that the collector has an inner jacket, wherein the inner jacket and outer jacket are arranged coaxially with each other, so that a flow channel for the refrigerant is formed between the inner jacket and the outer jacket, wherein the one inlet or outlet opening by means of the transfer line with that of the inner jacket enclosed space communicates and the other inlet or outlet opening is arranged in the outer jacket.

In dem Raum, der von dem Innenmantel umschlossen ist, befindet sich ein Trockner und gemäß einer Ausführung auch ein Filter.In the room, which is enclosed by the inner shell, there is a dryer and according to an embodiment, a filter.

Es kann auch vorgesehen werden, dass der Filter oberhalb des Trockners angeordnet ist, wobei das gereinigte Kältemittel nach Durchströmung des Filters seine Strömungsrichtung umkehrt und über den Strömungskanal und die andere Ein - oder Ausströmöffnung in die genannte Stufe des Kondensators eintritt.It can also be provided that the filter is arranged above the dryer, wherein the cleaned refrigerant after flowing through the filter reverses its direction of flow and enters the said stage of the condenser via the flow channel and the other inlet or outlet opening.

Es kann demgegenüber vorgesehen werden, dass sich in dem Raum, der von dem Innenmantel umschlossen ist, nur der Trockner befindet und dass der Filter im Strömungsweg vor der Ausströmöffnung angeordnet ist.In contrast, it can be provided that only the dryer is located in the space which is enclosed by the inner jacket, and that the filter is arranged in the flow path in front of the outflow opening.

Es ist eine Überführungsleitung von einer Stufe zu der einen Ein - oder Ausströmöffnung des Sammlers vorgesehen. Die Überführungsleitung erstreckt sich etwa über den Bereich der benachbarten Stufe. Die andere Ein - oder Ausströmöffnung des Sammlers ist etwa am stirnseitigen Ende des Sammelrohres vorgesehen. Dadurch wurde eine besonders kompakte Anordnung geschaffen, die sich hervorragend zu einer einzigen Lötkonstruktion verbinden lässt. Jede Stufe besteht aus mehreren parallelen Wärmetauscherrohren des Kondensators. Ferner wird durch das Vorsehen der Überführungsleitung die Position des Sammlers verbessert. In der Fig. 7 des EP 769 666 A1 befindet sich der Sammler vor oder hinter dem Rohr - Rippen - Block, so dass der Wärmeaustausch zwischen der senkrecht zum Rohr - Rippen - Block einströmenden Kühlluft und dem innerhalb des Rohr - Rippen - Blocks strömenden Kältemittel beeinträchtigt ist. Nach der Erfindung hingegen befindet sich der Sammler seitlich neben dem Rohr - Rippen - Block, wodurch die Effizienz des Wärmeaustausches verbessert wurde. Mit Hilfe der Überführungsleitung wird das Kältemittel von der einen Stufe über die andere Stufe hinweg bis in den Sammler hinein überführt. Nach dem Durchströmen des Sammlers tritt das Kältemittel in die erwähnte andere Stufe ein und durchströmt diese. Diese andere Stufe kann beispielsweise eine Unterkühlungsstufe sein.There is provided a transfer line from one stage to the one inlet or outlet of the collector. The transfer line extends approximately over the area of the adjacent stage. The other inlet or outlet opening of the collector is provided approximately at the front end of the collecting tube. As a result, a particularly compact arrangement was created, which can be perfectly combined to form a single Lötkonstruktion. Each stage consists of several parallel heat exchanger tubes of the condenser. Furthermore, the provision of the transfer line improves the position of the collector. In the Fig. 7 of EP 769 666 A1 the collector is located in front of or behind the tube - fin block, so that the heat exchange between the cooling air flowing in perpendicular to the tube - fin block and the refrigerant flowing inside the tube - fin block is impaired. After the invention however, the collector is laterally adjacent to the tube-and-finned block, improving the efficiency of heat exchange. With the help of the transfer line, the refrigerant is transferred from one stage to the other via the other stage into the collector. After flowing through the collector, the refrigerant enters the mentioned other stage and flows through it. This other stage may, for example, be a subcooling stage.

Die Überführungsleitung kann entweder innerhalb des Sammelrohrs oder außerhalb des Sammelrohrs angeordnet sein. Die Kompaktheit wird weiter verbessert, wenn eine innerhalb des Sammelrohres angeordnete Überführungsleitung gewählt wird. Hier kann es sich um ein etwa koaxiales Rohr handeln. Das Sammelrohr könnte im Bereich der Überführungsleitung aber auch lediglich durch eine Wand unterteilt sein.The transfer line may be located either within the header or outside the header. The compactness is further improved when a transfer line disposed within the manifold is selected. This may be an approximately coaxial tube. The manifold could be divided in the transfer line but also only by a wall.

Die andere Ein - oder Ausströmöffnung ist vorzugsweise unmittelbar zwischen dem Mantel des Sammlers und dem stirnseitigen Ende des Sammelrohres vorgesehen. Dadurch befindet sich der Sammler in unmittelbarer Nähe des Rohr - Rippen - Blocks und insbesondere in unmittelbarer Nähe und parallel zu einem der Seitenteile, die den Rohr - Rippen - Block gewöhnlich an den Seiten verstärken. An diesen Seitenteilen kann im Bedarfsfall eine zusätzliche Halterung des Sammlers vorgesehen werden.The other inlet or outflow opening is preferably provided directly between the jacket of the collector and the front end of the collecting tube. As a result, the collector is located in the immediate vicinity of the tube - fin block, and in particular in the immediate vicinity and parallel to one of the side parts, which usually reinforce the tube - rib block on the sides. If necessary, an additional mounting of the collector can be provided on these side parts.

Der erfindungsgemäße Kondensator ist besonders zur Kombination mit einem Wasserkühler und/oder anderen Wärmetauschern des Kraftfahrzeuges geeignet, die ebenfalls oben und unten horizontal angeordnete Sammelkästen und vertikale Wärmetauscherrohre aufweisen.The capacitor according to the invention is particularly suitable for combination with a water cooler and / or other heat exchangers of the motor vehicle, which also have top and bottom horizontally arranged collecting tanks and vertical heat exchanger tubes.

Nachfolgend wird die Erfindung in zwei bevorzugten Ausführungsbeispielen an Hand der beiliegenden Abbildungen beschrieben. Aus dieser Beschreibung gehen weitere Merkmale und Vorteile der Erfindung hervor, die sich als besonders wesentlich herausstellen können.The invention will be described in two preferred embodiments with reference to the accompanying drawings. From this description, further features and advantages of the invention will become apparent which may prove to be particularly essential.

Die Fig. 1 - 4 zeigen ein Ausführungsbeispiel mit einer außen liegenden Überführungsleitung und mit einem unterhalb des Behalter liegenden Filters. Die Fig. 5 - 8 zeigen ein Ausführungsbeispiel mit einer im Sammelrohr integrierten Überführungsleitung, und mit im Behälter vorhandenem Filter. Die Fig. 9 zeigt ein aufgeweitetes Sammelrohr mit integrierter Überführungsleitung.The Fig. 1 - 4th show an embodiment with an external transfer line and a lying below the container filter. The Fig. 5-8 show an embodiment with an integrated in the manifold transfer line, and with existing filter in the container. The Fig. 9 shows a flared manifold with integrated transfer line.

Die in den Ausführungsbeispielen angedeuteten Stufen 1 und 2 bestehen jeweils aus mehreren flachen Wärmetauscherrohren 15, wobei zwischen den Wärmetauscherrohren 15 Wellrippen 18 angeordnet sind, die von der Kühlluft durchströmt werden, um das Kältemittel in den Wärmetauscherrohren 15 zu kühlen bzw. zu kondensieren. Das Kältemittel verlässt im vollständig verflüssigten und unterkühlten Zustand den Kondensator 30.The indicated in the embodiments stages 1 and 2 each consist of a plurality of flat heat exchanger tubes 15 , wherein between the heat exchanger tubes 15 corrugated fins 18 are arranged, which are flowed through by the cooling air to cool the refrigerant in the heat exchanger tubes 15 and to condense. The refrigerant leaves the condenser 30 in the fully liquefied and supercooled state.

Bei dem in den Fig. 1 und 5 dargestellten Ausschnitten aus dem Kondensator 30 handelt es sich deshalb bei der Stufe 1 um mehrere Stufen, die vorgeschaltet sind, wie es prinzipiell aus den Fig. 2 und 6 erkennbar ist. Die Stufen 1, 2 entstehen durch die zweckmäßige Anordnung von Trennwänden 7 in den Sammelrohren 3 und 5.In the in the Fig. 1 and 5 Therefore, in the stage 1 shown sections of the capacitor 30 are at several stages, which are connected upstream, as it is in principle from the Fig. 2 and 6 is recognizable. The steps 1, 2 are formed by the appropriate arrangement of partitions 7 in the headers 3 and 5 .

In den Fig. 1 und 2 tritt das Kältemittel 25 durch den Eintritts - und Austrittsflansch 26 in den Kondensator 30 ein. Es fließt durch mehrere Stufen 1 bevor es durch die Einlassöffnung 27 in die Überführungsleitung 10 eintritt. Durch die Überführungsleitung 10 wird das gesamte Kältemittel 25 an der Stufe 2 vorbeigeleitet und in den Sammler 4 überführt. Am Flansch 8 tritt die Überführungsleitung 10 in den Sammler 4 ein und durchquert den Raum 28, den Filter 29 und gibt oberhalb des Filters 29 das flüssige mit geringen Gasanteilen vermischte Kältemittel 25 über die Einströmöffnung 14 in das Innere des Sammlers 4 ab. Im Sammler 4 befindet sich das Trocknungsmittel in einem Behälter 12. Auf seinem weiteren Weg strömt das Kältemittel durch den Filter 29, um kleinste Partikel abzuscheiden und in den Rückströmraum 28. Die Trennstege 36 sollen garantieren, dass das gesamte Kältemittel 25 durch den Filter 29 strömt.

In Fig. 5 und 6 tritt das Kältemittel 25 durch den Eintritts- und Austrittsflansch 26 in den Kondensator 30 ein. Es fließt durch mehrere Stufen 1 bevor es durch die Einlassöffnung 27 in die Überführungsleitung 10 eintritt. Durch die Überführungsleitung 10 wird das gesamte Kältemittel 25 an der Stufe 2 vorbei geleitet und in den Sammler 4 überführt. Am Flansch 8 tritt die Überführungsleitung 10 in den Sammler 4 ein. Am Flasch 8 befindet sich auch die Einströmöffnung 14, durch den das Kältemittel 25 in einen Innenmantel 20 einströmt. Im Innenmantel 20 befindet sich das Trocknungsmittel in einem Behälter 12. Auf seinem weiteren Weg passiert es den oberhalb des Trockners angeordneten Filter 29 um kleinste Partikel abzuscheiden. Zwischen dem Außenmantel 31 des Sammlers 4 und dem Innenmantel 20 befindet sich der Strömungskanal 16, durch den das Kältemittel 25 nach unten fließen kann. Über die Ausströmsöffnung 13 am Flansch 9 verlässt das Kältemittel 25 den Sammler 4 und strömt durch das stirnseitige Ende 35 des Sammelrohres 3 in die Stufe 2 des Kondensators 30. Nach der Unterkühlung in der Stufe 2 gelangt es über das Sammelrohr 5 und den Auslass 19 zum Ein - undIn Fig. 5 and 6 the refrigerant 25 enters the condenser 30 through the inlet and outlet flange 26 . It flows through several stages 1 before it enters the transfer line 10 through the inlet opening 27 . Through the transfer line 10 , the entire refrigerant 25 is passed to the stage 2 over and transferred to the collector 4 . At the flange 8 , the transfer line 10 enters the collector 4 a. On the bottle 8 is also the inflow opening 14 , through which the refrigerant 25 flows into an inner jacket 20 . In the inner jacket 20 , the desiccant is in a container 12th On his way It happens to the above the dryer arranged filter 29 to separate the smallest particles. Between the outer jacket 31 of the collector 4 and the inner shell 20 is the flow channel 16 , through which the refrigerant 25 can flow down. Via the outflow opening 13 on the flange 9 , the refrigerant 25 leaves the collector 4 and flows through the front end 35 of the collecting tube 3 into the stage 2 of the condenser 30 .

Austrittsflansch 26. In Fig. 8 ist noch eine Alternative zum zweiten Ausführungsbeispiel gezeigt. In einigen Fällen kann es notwendig sein, den Sammler 4 etwas vor oder hinter der Ebene 33 des Rohr - Rippen - Blocks des Kondensators 1 anzuordnen. Der Sammler 4 ist dann um den Abstand 32 aus der Ebene 33 nach vorn oder hinten versetzt, aber ansonsten identisch mit dem zweiten Ausführungsbeispiel.Outlet flange 26. In Fig. 8 is still an alternative to the second embodiment shown. In some cases it may be necessary to place the collector 4 slightly in front of or behind the plane 33 of the tube - fin block of the condenser 1 . The collector 4 is then offset by the distance 32 from the plane 33 to the front or rear, but otherwise identical to the second embodiment.

In Fig. 9 ist noch eine alternative Ausbildung einer Überführungsleitung gezeigt. Hier ist lediglich ein Ausschnitt des Sammelrohres 3 zu sehen. In diesem Fall wurde das Sammelrohr 3 auf der dem Sammler 4 zugewandten Seite 35 im Durchmesser vergrößert. Vor der letzten Trennwand 7 im Sammelrohr 3 ist das Sammelrohr 3 aufgeweitet worden, um die Überführungsleitung 10 aufzunehmen, damit das zurückfließende Kältemittel 25 keinen unnötigen Druckverlust durch ein zu enges Sammelrohr 3 erfährt. Außerdem ist der Einbau der Überführungsleitung 10 leichter zu bewerkstelligen.In Fig. 9 is still shown an alternative embodiment of a transfer line. Here is only a section of the manifold 3 can be seen. In this case, the manifold 3 was enlarged on the collector 4 side facing 35 in diameter. Before the last partition wall 7 in the manifold 3 , the manifold 3 has been widened to accommodate the transfer line 10 so that the returning refrigerant 25 undergoes no unnecessary pressure loss through a too narrow manifold 3 . In addition, the installation of the transfer line 10 is easier to accomplish.
