Description

Die Erfindung betrifft einen Wärmeübertrager, insbesondere für ein Kraftfahrzeug nach dem Oberbegriff des Patentanspruches 1 - bekannt durch die EP 1 589 311 A1 der Anmelderin.The invention relates to a heat exchanger, in particular for a motor vehicle according to the preamble of claim 1 - known by the EP 1 589 311 A1 the applicant.

Durch die EP 1 589 311 A1 der Anmelderin wurde ein gelöteter Kondensator für eine Kraftfahrzeug-Klimaanlage mit einem Rohr-Rippen-Block und zwei Sammelrohren bekannt, an welchen Zusatzteile, insbesondere Halter oder ein Kältemittelrohrflansch befestigt sind. Das Zusatzteil, z. B. der Halter weist ein gabelförmiges oder U-förmig ausgebildetes Profilstück auf, welches an den Umfang des Sammelrohres angepasst ist und dieses umfasst. Im dargestellten Ausführungsbeispiel ist das Sammelrohr zweistückig ausgebildet, d. h. es weist ein Bodenteil und ein Deckelteil auf, welche ineinander gesteckt und miteinander verlötet werden. Dadurch werden zwei abgesetzte Längskanten gebildet, welche als Anschlagflächen für das entsprechend ausgebildete Profilstück dienen. Damit wird eine formschlüssige Fixierung und Positionierung des Halters gegenüber dem Sammelrohr erreicht.By the EP 1 589 311 A1 The Applicant has disclosed a soldered condenser for an automotive air conditioner having a tube-fin block and two header tubes to which attachments, particularly holders or a refrigerant tube flange, are attached. The additional part, z. As the holder has a fork-shaped or U-shaped profiled piece, which is adapted to the circumference of the manifold and this includes. In the illustrated embodiment, the manifold is formed in two pieces, ie it has a bottom part and a lid part, which are inserted into one another and soldered together. As a result, two offset longitudinal edges are formed, which serve as abutment surfaces for the correspondingly formed profile piece. For a positive fixation and positioning of the holder is achieved with respect to the manifold.

Durch die EP 1 443 294 A1 der Anmelderin wurde ein Kältemittelkondensator für Kraftfahrzeuge mit einem Sammelrohr bekannt, an welchem ein Flansch mittels eines Halters durch eine Lötverbindung befestigt ist. Das Sammelrohr ist zweistückig, d. h. mit Boden- und Deckelteil ausgebildet und weist daher abgesetzte Längskanten auf. Der Halter weist ein durch Extrusion hergestelltes C-förmiges Profil auf, welches auf seiner Innenseite Absätze aufweist, welche sich an den abgesetzten Längskanten des Sammelrohres abstützen. Damit wird ebenfalls eine Fixierung und Positionierung des Flansches auf dem Sammelrohr erreicht.By the EP 1 443 294 A1 The applicant has disclosed a motor vehicle refrigerant condenser having a header to which a flange is fixed by means of a holder by a solder joint. The manifold is in two pieces, ie formed with bottom and lid part and therefore has offset longitudinal edges. The holder has a manufactured by extrusion C-shaped profile, which has on its inside paragraphs which are supported on the remote longitudinal edges of the manifold. This also fixation and positioning of the flange is achieved on the manifold.

Ein Problem bei der Herstellung der bekannten Wärmeübertrager, insbesondere Kondensatoren für Kraftfahrzeug-Klimaanlagen besteht in der Befestigung der Zusatzteile an den Sammelrohren, welche aufgrund des hohen Innendruckes in der Regel einen runden oder annähernd kreisförmigen Querschnitt aufweisen. Bei zweiteilig ausgebildeten Sammelrohren ergeben sich - wie oben beschrieben - abgesetzte Längskanten, an welchen die Zusatzteile bzw. Halter abgestützt werden und somit an einem Verdrehen um die Längsachse (Z-Achse) des Sammelrohres gehindert werden können. Es sind jedoch auch Sammelrohre mit einem geschlossenen runden Rohrquerschnitt bekannt, d. h. Sammelrohre, die im Wesentlichen einstückig ausgebildet sind, z. B. längsnahtgeschweißte Aluminiumrohre, welche ebenfalls für Kondensatoren verwendet werden. Hier tritt das Problem auf, dass die auf das runde Sammelrohr aufgesetzten Halter gegen Verdrehen um die Längsachse des Sammelrohres nicht gesichert sind.A problem in the production of the known heat exchanger, in particular capacitors for automotive air conditioning systems consists in the attachment of the additional parts to the manifolds, which usually have a round or approximately circular cross-section due to the high internal pressure. In two-part headers arise - as described above - remote longitudinal edges on which the additional parts or holders are supported and thus can be prevented from twisting about the longitudinal axis (Z-axis) of the manifold. However, there are also known manifolds with a closed round tube cross-section, d. H. Collecting tubes, which are formed substantially in one piece, for. B. longitudinally welded aluminum tubes, which are also used for capacitors. Here, the problem arises that the mounted on the round manifold holder are not secured against rotation about the longitudinal axis of the manifold.

Durch die EP 0 599 972 B1 wurde ein gelöteter Flachrohrkondensator für Kraftfahrzeug-Klimaanlagen bekannt. Der Kondensator weist ein zweiteilig ausgebildetes Sammelrohr auf, welches aus einem extrudierten Deckelteil sowie einem gestanzten und gebogenen Bodenteil zusammengesetzt ist. Das extrudierte Deckelteil weist einen einstückig angeformten Halter in Form einer durchgehenden Halteleiste und eine abgeflachte, durchgehende Rippe auf der Oberseite auf. Bei dem bekannten Sammelrohr ist keine Befestigung von Zusatzteilen vorgesehen, vielmehr ist der einzige Halter einstückig mit dem Deckel ausgebildet - nachteilig hierbei ist, dass der gesamte Deckel des Sammelrohres durch Extrudieren hergestellt wird.By the EP 0 599 972 B1 a soldered flat tube condenser for automotive air conditioning was known. The condenser has a collecting tube formed in two parts, which is composed of an extruded cover part and a stamped and bent base part. The extruded lid part has an integrally formed holder in the form of a continuous retaining strip and a flattened, continuous rib on the top. In the known manifold no attachment of additional parts is provided, but the sole holder is formed integrally with the lid - disadvantageous here is that the entire lid of the manifold is made by extrusion.

Es ist Aufgabe der vorliegenden Erfindung, einen Wärmeübertrager der eingangs genannten Art derart auszubilden, dass die am Sammelrohr zu befestigenden Zusatzteile gegen Verdrehen gegenüber der Sammelrohrlängsachse fixierbar sind und dass eine feste Verbindung zwischen Sammelrohr und Zusatzteil erreicht wird.It is an object of the present invention, a heat exchanger of the type mentioned in such a way that to be fastened to the manifold Additional parts against rotation relative to the manifold longitudinal axis are fixed and that a firm connection between manifold and attachment is achieved.

Mit der erfindungsgemäßen, einen Formschluss auslösenden Mitnahmefläche wird der Vorteil erreicht, dass das Zusatzteil, welches auf dem Sammelrohr befestigt wird, nicht mehr um die Längsachse des Sammelrohres rotieren kann, sondern aufgrund der Mitnahmeflächen gehalten und gleichzeitig in seiner Lage ausgerichtet wird. Die sichere Fixierung und eindeutige Ausrichtung ist für den nachfolgenden Lötprozess des Wärmeübertragers wichtig. Darüber hinaus wird durch die Mitnahmefläche eine erhöhte Festigkeit der Verbindung zwischen Zusatzteil und Sammelrohr erreicht.According to the invention it is provided that at least one driving surface is provided both at the periphery of the collecting tube and on the profile piece embracing the collecting tube, which brings about a positive connection between the two parts.

H. is formed inwardly or outwardly. With the invention, a form-fit triggering driving surface of the advantage is achieved that the additional part which is mounted on the manifold, can no longer rotate about the longitudinal axis of the manifold, but held due to the driving surfaces and simultaneously aligned in its position. The secure fixation and clear alignment is important for the subsequent soldering process of the heat exchanger. In addition, an increased strength of the connection between the additional part and manifold is achieved by the driving surface.
