Description
Joh. Vaillant GmbH u. Co. GM 1599Joh. Vaillant GmbH u. Co. GM 1599
Die Erfindung bezieht sich auf einen Wärmetauscher gemäß dem Oberbegriff des Anspruches 1.The invention relates to a heat exchanger according to the preamble of claim 1.
Bei bekannten derartigen Wärmetauschern sind die Enden der einzelnen Wärmetauscherrohre über Krümmer miteinander verbunden. Dabei ergibt sich jedoch der Nachteil, daß die Krümmer mit den Wärmetauscherrohren meist durch Schweißen miteinander verbunden werden müssen, was mit einem entsprechend hohen Aufwand verbunden ist. Außerdem kann nie ganz ausgeschlossen werden, daß es zu einem Durchschweißen der die Wärmetauscherrohre mit den Krümmern verbindenden Nähte kommt und dadurch unregelmäßig geformte Vorsprünge in den lichten Rohrquerschnitt hineinragen, die den Durchströmungswiderstand erhöhen.In known heat exchangers of this type, the ends of the individual heat exchanger tubes are connected to one another via elbows. However, this has the disadvantage that the elbows usually have to be connected to the heat exchanger tubes by welding, which is associated with a correspondingly high level of effort. In addition, it can never be completely ruled out that the seams connecting the heat exchanger tubes to the elbows will be welded through, resulting in irregularly shaped projections protruding into the clear pipe cross-section, increasing the flow resistance.
Ziel der Erfindung ist es, diese Nachteile zu vermeiden und einen Wärmetauscher der eingangs erwähnten Art vorzuschlagen, der sich einfach herstellen läßt und bei dem in den lichten Querschnitt der Wärmetauscherrohre hinragende Ansätze oder dergleichen sicher vermieden sind.The aim of the invention is to avoid these disadvantages and to propose a heat exchanger of the type mentioned at the outset which is easy to manufacture and in which projections or the like protruding into the clear cross-section of the heat exchanger tubes are reliably avoided.
Erfindungsgemäß wird dies bei einem Wärmetauscher der eingangs erwähnten Art durch die kennzeichnenden Merkmale des Anspruches 1 erreicht.According to the invention, this is achieved in a heat exchanger of the type mentioned at the outset by the characterizing features of claim 1.
Durch die vorgeschlagenen Maßnahmen ist es auf einfache Weise möglich, die Enden der einzelnen Wärmetauscherrohre miteinander hydraulisch zu verbinden. Dabei genügt es, dieThe proposed measures make it possible to connect the ends of the individual heat exchanger tubes hydraulically in a simple manner. It is sufficient to
Hauben unter Zwischenlage einer Dichtung, zum Beispiel einer Schnurdichtung, an der Außenseite des Heizschachtes an diesen anzubringen, wobei sich mindestens zwei Enden von nebeneinander angeordneten Wärmetauscherrohren innerhalb der Haube befinden.Hoods are to be attached to the outside of the heating shaft with a seal, for example a cord seal, in between, with at least two ends of heat exchanger tubes arranged next to each other located inside the hood.
Die Befestigung der Hauben kann dabei zum Beispiel mittels Schrauben oder entsprechenden Spanneinrichtungen erfolgen, die für eine entsprechende Anpressung der Hauben an die Wand des Heizschachtes sorgt.The hoods can be attached using screws or appropriate clamping devices, for example, which ensure that the hoods are pressed against the wall of the heating shaft.
Durch die Merkmale des Anspruches 2 ergibt sich der Vorteil, daß die Montage der Umienkungen sehr einfach und rasch erfolgen kann, wobei nur wenige Befestigungsmittel erforderlich sind.The features of claim 2 result in the advantage that the assembly of the deflections can be carried out very easily and quickly, with only a few fastening means being required.
Die Erfindung wird nun anhand der Zeichnung näher erläutert. Dabei zeigen:The invention will now be explained in more detail with reference to the drawing.
Fig. 1 schematisch eine Ansicht eines erfindungsgemäßen Wärmetauschers, Fig. 2 einen Schnitt entlang der Linie H-Il in der Fig. 1,Fig. 1 shows a schematic view of a heat exchanger according to the invention, Fig. 2 shows a section along the line H-II in Fig. 1,
Fig. 3 bis 6 geprägte Haltebleche undFig. 3 to 6 embossed retaining plates and
Fig. 7 bis 9 ein Halteblech als Druckgußteil.Fig. 7 to 9 a retaining plate as a die-cast part.
Gleiche Bezugszeichen bedeuten in allen Figuren gleiche Einzelheiten.The same reference symbols indicate the same details in all figures.
An der Außenseite eines Heizschachtes 1, dessen Wand 5 von Wärmetauscherrohren 2 durchsetzt ist, ist eine Haube 3 befestigt, die mit einer Mehrzahl an Vertiefungen 4 versehen ist.A hood 3 provided with a plurality of recesses 4 is attached to the outside of a heating shaft 1, the wall 5 of which is penetrated by heat exchanger tubes 2.
Dabei überdeckt jede Vertiefung 4 der Haube 3 mindestens zwei Enden benachbarter Wärmetauscherrohre 2, so daß das aus einem Wärmetauscherrohr 2 austretende Wasser in der Vertiefung zu den benachbarten Wärmetauscherrohren 2 strömen kann und dadurch umgelenkt wird.Each recess 4 of the hood 3 covers at least two ends of adjacent heat exchanger tubes 2, so that the water emerging from a heat exchanger tube 2 can flow in the recess to the adjacent heat exchanger tubes 2 and is thereby diverted.
Wie aus der Fig. 2 zu ersehen ist, ist die Wand 5 im Bereich der Wärmetauscherrohre 2 mit einer Platte 6 verstärkt, die die Dichtungen zur gasseitigen 8 und zur wasserseitigen 12 Abdichtung aufnimmt und gemeinsam mit der Haube 3 am Wärmetauscher 5 befestigt ist.As can be seen from Fig. 2, the wall 5 in the area of the heat exchanger tubes 2 is reinforced with a plate 6, which accommodates the seals for the gas side 8 and the water side 12 sealing and is attached to the heat exchanger 5 together with the hood 3.
Die Haube 3 ist mit mehreren Stehbolzen 9 an der Platte 6 am Wärmetauscher 5 befestigt.The hood 3 is attached to the plate 6 on the heat exchanger 5 with several stud bolts 9.
