Darstellung der Erfindung, Aufgabe, Lösung, VorteilePresentation of the invention, object, solution, advantages

Es ist die Aufgabe der Erfindung, einen Kondensator mit einem extrudierten Sammler benachbart zu einem Sammelrohr zu schaffen, der einfach und kostengünstig herstellbar ist und dennoch eine gute thermische Trennung zwischen dem Sammler und dem Sammelrohr aufweist.It is the object of the invention to provide a condenser with an extruded header adjacent to a header which is simple and inexpensive to produce and yet has good thermal separation between the header and the header.

Die vorliegende Erfindung ist im unabhängigen Anspruch 1 offenbart. Dadurch wird erreicht, dass eine Erwärmung des Kältemittels im Sammler nicht oder nur geringfügig durch das wärmere Kältemittel im parallel dazu angeordneten Sammelrohr erwärmt wird.The present invention is disclosed in independent claim 1. This ensures that heating of the refrigerant in the collector is not or only slightly heated by the warmer refrigerant in the manifold arranged parallel thereto.

Erfindungsgemäß weist der Sammler einen seitlichen Ansatz auf, in welchem Überströmöffnungen angeordnet sind, wobei ein Wandbereich des Sammelrohrs mit dem Sammler mit dem dazwischen angeordneten seitlichen Ansatz einteilig ausgebildet ist. Dadurch kann die Teilezahl reduziert werden, was kostengünstig realisiert werden kann.According to the invention, the collector has a lateral approach, in which overflow openings are arranged, wherein a wall region of the collecting tube is integrally formed with the collector with the lateral projection arranged therebetween. As a result, the number of parts can be reduced, which can be realized inexpensively.

Auch ist es zweckmäßig, wenn die thermische Trennung in dem seitlichen Ansatz durch zumindest eine Ausnehmung ausgebildet ist.It is also expedient if the thermal separation in the lateral projection is formed by at least one recess.

Erfindungsgemäß sind eine Mehrzahl von Ausnehmungen oberhalb der Überströmöffnungen angeordnet, die sich bis zu einem entfernten axialen Ende des Sammlers erstrecken. Dadurch wird eine Art Netz von Stegen erzeugt, was die thermische Leitfähigkeit reduziert.According to the invention, a plurality of recesses are arranged above the overflow openings, which extend to a distal axial end of the collector. This creates a kind of web of lands, which reduces thermal conductivity.

Erfindungsgemäß sind eine Mehrzahl von Ausnehmungen vorgesehen, die in einer Reihe oder in mehreren Reihen benachbart zueinander angeordnet sind und jeweils durch Stege voneinander getrennt sind. Dadurch wird eine Art geordnetes Netz von Stegen erzeugt, was die thermische Leitfähigkeit reduziert.According to the invention, a plurality of recesses are provided, which are arranged in a row or in a plurality of rows adjacent to each other and are separated from each other by webs. This creates a kind of ordered network of webs, which the reduced thermal conductivity.

Dabei weisen die Ausnehmungen eine längliche Kontur auf. Dadurch kann eine größere Anzahl von Stegen erzeugt werden, die definierte Abstände zueinander aufweisen.The recesses have an elongated contour. As a result, a larger number of webs can be generated, which have defined distances from one another.

Weitere vorteilhafte Ausgestaltungen sind durch die nachfolgende Figurenbeschreibung und durch die Unteransprüche beschrieben.Further advantageous embodiments are described by the following description of the figures and by the subclaims.

Die Figur 1 zeigt in einer schematischen Darstellung einen Kondensator 1 mit einem Rohr-Rippen-Block 2, welcher gebildet ist durch eine Mehrzahl von beabstandet zueinander angeordneten Rohren 3 und dazwischen angeordneten Rippen 4. Die Rohre 3 sind mit beiderseits des Rohr-Rippen-Blocks angeordneten Sammelrohren 5 verbunden, in dem die Rohre 3 durch Öffnungen 6 des Sammelrohrs 5 eingreifen und abgedichtet darin angeordnet sind, so dass eine Fluidverbindung zwischen dem Innenraum des Rohrs 3 und dem Innenraum des Sammelrohrs 5 vorhanden ist. Parallel zu einem der Sammelrohre 5 ist ein Sammler 7 angeordnet, welcher über Überströmöffnungen 8, 9 mit dem Sammelrohr 5 in Fluidverbindung steht.The FIG. 1 shows a schematic representation of a condenser 1 with a tube-fin block 2, which is formed by a plurality of spaced apart tubes 3 and arranged therebetween ribs 4. The tubes 3 are arranged on both sides of the tube-fin block manifolds fifth in which the tubes 3 engage through openings 6 of the collecting tube 5 and are arranged sealed therein, so that a fluid connection between the interior of the tube 3 and the interior of the collecting tube 5 is present. Parallel to one of the manifolds 5, a collector 7 is arranged, which communicates via overflow openings 8, 9 with the manifold 5 in fluid communication.

Im Beispiel der Figur 1 ist der Sammler 7 mit dem Sammelrohr 5 einstückig ausgebildet, wobei der Sammler 7 mit dem Sammelrohr 5 beispielsweise als extrudiertes Bauteil in einem Prozess hergestellt wird, wobei das dadurch erhaltene Profil anschließend durch beispielsweise spanende oder spanlose Bearbeitung weiterverarbeitet werden kann, um beispielsweise die Überströmöffnungen 8, 9 beziehungsweise die Rohröffnungen 6 einzubringen.In the example of FIG. 1 the collector 7 is integrally formed with the manifold 5, the collector 7 is made with the manifold 5, for example, as an extruded component in a process, the profile thus obtained can then be further processed by, for example, cutting or non-cutting processing, for example, the overflow. 8 , 9 or the pipe openings 6 introduce.

Die Figur 2 zeigt einen Teil eines Kondensators 11 mit einem Sammelrohr 15 und einem Sammler 17. Dabei ist die Verbindung zwischen dem Sammelrohr 15 und dem Sammler 17 auf den Bereich 18 der Überströmöffnungen 12, 13 beschränkt, wobei die Überströmöffnungen in einem Block angeordnet sind, der zwischen dem Sammelrohr 15 und dem Sammler 17 vorliegt. Oberhalb des Blocks 18 ist eine thermische Trennung 19 zwischen dem Sammelrohr 15 und dem Sammler 17 ausgebildet.The FIG. 2 shows a portion of a condenser 11 with a manifold 15 and a collector 17. In this case, the connection between the manifold 15 and the collector 17 is limited to the region 18 of the overflow openings 12, 13, wherein the overflow openings are arranged in a block which between the Collector 15 and the collector 17 is present. Above the block 18, a thermal separation 19 between the manifold 15 and the collector 17 is formed.

Die beiden Figuren 1, 2 zeigen, dass der Sammler 17 einen seitlichen Ansatz 10, 18 aufweist, in welchem die Überströmöffnungen 8, 9, 12, 13 angeordnet sind, wobei der Sammler 7, 17 nur im Bereich dieses seitlichen Ansatzes mit dem Sammelrohr 5, 15 verbunden ist. Im dargestellten Beispiel der Figur 2 ist der Sammler 17 nur im Bereich des seitlichen Ansatzes mit dem benachbarten Sammelrohr 15 verbunden, wobei die axiale Länge L des seitlichen Ansatzes derart dimensioniert ist, dass er auf die Aufnahme der Überströmöffnungen beschränkt ist.The two FIGS. 1, 2 show that the collector 17 has a lateral projection 10, 18, in which the overflow openings 8, 9, 12, 13 are arranged, wherein the collector 7, 17 only in the region of this lateral approach with the manifold 5, 15 is connected. In the example shown the FIG. 2 the collector 17 is connected only in the region of the lateral approach to the adjacent manifold 15, wherein the axial length L of the lateral approach is dimensioned such that it is limited to the inclusion of the overflow.

Es ist bereits erwähnt, dass der Sammler mit seinem seitlichen Ansatz und das Sammelrohr einteilig ausgebildet sein können, wie beispielsweise durch Extrudieren. Alternativ dazu kann auch der Sammler mit seinem seitlichen Ansatz und ein Wandbereich des Sammelrohres einteilig ausgebildet sein. Dabei ist das Sammelrohr bevorzugt zweiteilig ausgebildet, mit einem Boden, in welchem die Öffnungen 6 eingebracht sind und einen Deckel, der den Boden zu einem geschlossenen Rohr verschließt. Dabei ist der Wandbereich, der mit dem Sammelrohr einteilig ausgebildet ist, bevorzugt der Deckel des Sammelrohrs.It has already been mentioned that the collector with its lateral extension and the manifold can be made in one piece, for example by extrusion. Alternatively, the collector may be formed integrally with its lateral approach and a wall portion of the manifold. In this case, the manifold is preferably formed in two parts, with a bottom in which the openings 6 are introduced and a lid which closes the bottom to a closed tube. In this case, the wall region, which is integrally formed with the manifold, preferably the cover of the manifold.

Die Figur 3 zeigt ein weiteres Beispiel in einer Teilansicht eines Kondensators 21 mit einem Sammelrohr 25 und einem Sammler 27, wobei oberhalb des seitlichen Ansatzes 28 eine thermische Trennung 29 vorgesehen ist. Dieses Beispiel ist genauso wie die beiden vorigen Beispiele nicht ein Teil der vorliegenden Erfindung. Am axialen Ende 22, welches von dem axialen Ende 23 des Sammlers beabstandet ist, an welchem der seitliche Ansatz 28 angeordnet ist, ist ein Steg 24 zur Verbindung zwischen dem Sammelrohr 25 oder zwischen einem Wandbereich des Sammelrohrs 25 einerseits und dem Sammler 27 andererseits vorgesehen. Hierbei kann es ebenso vorteilhaft und zweckmäßig sein, wenn der Sammler 27 mit dem Steg 24 und dem seitlichen Ansatz 28 sowie mit dem Sammelrohr oder zumindest mit einem Wandbereich des Sammelrohrs einstückig durch Extrudieren ausgebildet ist.The FIG. 3 shows a further example in a partial view of a condenser 21 with a manifold 25 and a collector 27, wherein above the lateral projection 28, a thermal break 29 is provided. This example, like the previous two examples, is not part of the present invention. At the axial end 22, which is spaced from the axial end 23 of the collector, on which the lateral projection 28 is arranged, a web 24 is provided for connection between the manifold 25 or between a wall portion of the manifold 25 on the one hand and the collector 27 on the other hand. It may also be advantageous and expedient if the collector 27 is integrally formed by extrusion with the web 24 and the lateral projection 28 and with the manifold or at least with a wall portion of the manifold.

Die Figur 5 zeigt auch ein Beispiel, das nicht ein Teil der vorliegenden Erfindung ist. Die Figuren 4 und 6 zeigen Ausführungsbeispiele der vorliegenden Erfindung. In den Figuren 4 bis 6 sind im seitlichen Ansatz 30 beziehungsweise 40 beziehungsweise 50 Ausnehmungen 31, 41 oder 51 eingebracht. Im Ausführungsbeispiel der Figur 4 sind Ausnehmungen in einer Reihe angeordnet, wobei die Ausnehmungen eine längliche Kontur aufweisen und zwischen sich Stege 32 bzw. 52 ausbilden. Dabei sind die Ausnehmungen oberhalb des Bereichs der Überströmöffnungen angeordnet. Im Beispiel der Figur 5 ist eine einzige Ausnehmung 41 vorgesehen, die sich im Wesentlichen über die gesamte Länge des seitlichen Ansatzes oberhalb der Überströmöffnungen ausbildet.The FIG. 5 also shows an example which is not part of the present invention. The FIGS. 4 and 6 show embodiments of the present invention. In the FIGS. 4 to 6 are in lateral approach 30 or 40 or 50 recesses 31, 41 or 51 introduced. In the embodiment of FIG. 4 recesses are arranged in a row, wherein the recesses have an elongated contour and form webs 32 and 52 between them. The recesses are arranged above the region of the overflow openings. In the example of FIG. 5 a single recess 41 is provided which forms substantially over the entire length of the lateral projection above the overflow openings.

Die Figur 6 zeigt ein weiteres Ausführungsbeispiel der Erfindung, bei welchem Ausnehmungen 51 in benachbarten Reihen angeordnet sind, wobei die Ausnehmungen 51 von Reihe zu Reihe in axialer Richtung versetzt zueinander ausgebildet sind, so dass sich ein Netzwerk von Stegen 52 bildet.The FIG. 6 shows a further embodiment of the invention, in which recesses 51 are arranged in adjacent rows, wherein the recesses 51 are formed from row to row in the axial direction offset from each other, so that a network of webs 52 is formed.
