Dieser Wärmeübertrager wurde am 22.07.03 beim DPMA angemeldet und erhielt das Aktenzeichen DE 103 33 150.6.This heat exchanger was registered with the DPMA on July 22, 2003 and received the file number DE 103 33 150.6.

Ein anderer nicht vorveröffentlichter Wärmeaustauscher wurde am 17.08.02 beim DPMA angemeldet und erhielt das Aktenzeichen DE 102 37 769.3.Another not previously published heat exchanger was on 17.08.02 at DPMA filed and received the file number DE 102 37 769.3.

Die Aufgabe der Erfindung besteht in der Weiterentwicklung dieses Standes der Technik. Insbesondere soll ein Wärmeaustauscher vorgeschlagen werden, dessen Herstellbarkeit, insbesondere hinsichtlich der Schaffung dichter und fester Lötverbindungen, weiter vereinfacht bzw. verbessert werden soll.The object of the invention consists in the development of this state of the Technology. In particular, a heat exchanger is to be proposed, whose Manufacturability, in particular with regard to the creation of denser and stronger Soldered, further simplified or improved.

Die erfindungsgemäße Lösung erfolgt bei dem im Oberbegriff des Patentanspruchs 1 beschriebenen Wärmeaustauscher durch dessen kennzeichnende Merkmale.The solution according to the invention is carried out in the preamble of claim 1 described heat exchanger by its characterizing features.

Weil die Längswände der Sammelkästen zwischen den Verbindungslängsrändern der Rohrböden angeordnet sind, wobei Vorsprünge an den Längswänden vorgesehen sind, die in korrespondierenden Öffnungen in den Rohrböden stecken, und weil die Verbindungsquerränder der Rohrböden einen Kontur - Ausschnitt aufweisen, um mit den Verschlusskappen eine dichte und feste Lötverbindung zu bilden, wurde eine weitere Verbesserung der Herstellbarkeit erreicht, wobei damit insbesondere hochwertige löttechnische Verbindungen gemeint sind. Die Vorsprünge in den Öffnungen bewirken, dass die Längswände der Sammelkästen beim Einsetzen ihrer Vorsprünge in die Öffnungen im Rohrboden dicht an die Verbindungslängsränder des Rohrbodens gepresst werden. Der Kontur - Ausschnitt in den Verbindungsquerrändern der Rohrböden führt zu dichten Lötverbindungen in den Eckbereichen der Rohrböden. Die Ausbildung von scharfkantigen Eckbereichen, wie sie in der nicht vorveröffentlichten Anmeldung vorgesehen ist, wird mit dieser vorgeschlagenen Ausbildung überflüssig bzw. umgangen. Der Kontur - Ausschnitt kann mit einer flanschartigen Abkantung weitergebildet werden, um die Verbindungsfläche mit der Verschlusskappe zu erhöhen. Diese Maßnahme kann insbesondere vorgesehen werden, wenn die Blechdicke des Rohrbodens reduziert werden soll.Because the longitudinal walls of the headers between the connecting longitudinal edges the tube sheets are arranged, with projections on the longitudinal walls are provided, which plug into corresponding openings in the tube sheets, and because the connecting transverse edges of the tubesheets have a contour cutout To use the caps with a tight and strong solder joint Forming, a further improvement in manufacturability was achieved, with it in particular high-quality soldering connections are meant. The projections in the openings cause the longitudinal walls of the collecting tanks when Inserting their projections in the openings in the tube sheet close to the Connecting longitudinal edges of the tubesheet are pressed. The contour - cutout in the connecting transverse edges of the tube sheets leads to dense solder joints in the corner areas of the tubesheets. The formation of sharp-edged corner areas, as provided in the non-prepublished application is with this proposed training superfluous or circumvented. The contour - cutout Can be further developed with a flange-like fold to the Increase connection area with the cap. This measure can be provided in particular when the sheet thickness of the tube sheet is reduced shall be.

Weitere erfindungsgemäße Weiterbildungen sind in den Ansprüchen enthalten.Further developments according to the invention are contained in the claims.

In den Figuren ist ein Wärmeaustauscher für Kraftfahrzeuge abgebildet, dessen Komponenten aus Flachrohren 1, aus Wellrippen 2, aus Rohrböden 3 mit Öffnungen 4 zur Aufnahme der Enden der Flachrohre 1 und mit Verbindungslängs - und Verbindungsquerrändern 5, 6, die vier Eckbereiche bilden, bestehen. Ferner besteht der Wärmeaustauscher aus Sammelkästen 7 mit zwei Längswänden 8, 9 zur Verbindung mit den Verbindungslängsrändern 5 und aus Seitenteilen 10 mit Verschlusskappen 11, zum Verschluss der seitlichen Öffnungen der Sammelkästen 7, wobei die Verschlusskappen 11 einen abgekanteten Rand 14 aufweisen. Außerdem sind im gezeigten Ausführungsbeispiel Mittel 15 zum Fixieren des Wärmeaustauschers am Rand des Sammelkastens 6 und am Rand 14 der Verschlusskappe 11 angeordnet, die zusammenwirken. Sämtliche erwähnten Teile des Wärmeaustauschers sind aus Aluminiumblech hergestellt, das zweckmäßig mit Lot beschichtet ist, zur metallischen Verbindung mittels eines Lötprozesses. In the figures, a heat exchanger for motor vehicles is shown, the components of flat tubes 1 , corrugated fins 2 , tube sheets 3 with openings 4 for receiving the ends of the flat tubes 1 and with Verbindungslängs - and connecting transverse edges 5 , 6 , which form four corner regions exist. Furthermore, the heat exchanger consists of collecting boxes 7 with two longitudinal walls 8 , 9 for connection to the connecting longitudinal edges 5 and side parts 10 with sealing caps 11 , for closing the lateral openings of the collecting boxes 7 , wherein the closure caps 11 have a bevelled edge 14 . In addition, in the illustrated embodiment, means 15 for fixing the heat exchanger at the edge of the collecting tank 6 and the edge 14 of the closure cap 11 are arranged, which cooperate. All mentioned parts of the heat exchanger are made of aluminum sheet, which is suitably coated with solder, for the metallic connection by means of a soldering process.

Die Längswände 8, 9 der Sammelkästen 7 sind zwischen den Verbindungslängsrändern 5 der Rohrböden 3 angeordnet, wobei Vorsprünge 20 an den Längswänden 8, 9 vorgesehen sind, die in korrespondierenden Öffnungen 30 in den Rohrböden 3 stecken. Die Verbindungsquerränder 6 der Rohrböden 3 weisen einen Kontur - Ausschnitt 40 auf, der mit den Verschlusskappen 11 eine dichte und feste Lötverbindung bildet. Die Vorsprünge 20 haben eine leicht konische Form, sodass eine gewisse Führung in die Öffnungen 30 hinein gewährleistet ist und dass auch gleichzeitig sichergestellt wird, dass die Vorsprünge 20 eng am Rand der Öffnungen 30 anliegen. Die Vorsprünge 20 und die Öffnungen 30 sind in zweckmäßigen Abständen angeordnet, um ihre Funktion erfüllen zu können. Da in den Bereichen rund um die Öffnungen 30 herum außerdem ausreichend Lotmaterial zur Verfügung steht, wird eine dichte Lötverbindung der Vorsprünge 20 in den Öffnungen 30 erwartet und gleichzeitig eine hohe Prozesssicherheit gewährleistet. Die Öffnungen 30 im Rohrboden 3 sind vorzugsweise zwischen den Öffnungen 4 für die Flachrohrenden angeordnet, damit eine maximale Tiefe des Rohr - Rippen - Blocks gewährleistet ist. Sie befinden sich ferner vorzugsweise unmittelbar am Verbindungslängsrand 5.The longitudinal walls 8 , 9 of the manifolds 7 are arranged between the connecting longitudinal edges 5 of the tubesheets 3 , wherein projections 20 are provided on the longitudinal walls 8 , 9 , stuck in corresponding openings 30 in the tube sheets 3 . The connecting transverse edges 6 of the tubesheets 3 have a contour cutout 40 which forms a tight and firm soldered connection with the closure caps 11 . The projections 20 have a slightly conical shape, so that a certain guidance is ensured in the openings 30 and that at the same time it is ensured that the projections 20 fit tightly against the edge of the openings 30 . The projections 20 and the openings 30 are arranged at appropriate intervals in order to fulfill their function. In addition, since sufficient solder material is available in the areas around the openings 30 , a dense solder joint of the projections 20 in the openings 30 is expected while ensuring high process reliability. The openings 30 in the tube sheet 3 are preferably arranged between the openings 4 for the flat tube ends, so that a maximum depth of the tube - rib block is ensured. Furthermore, they are preferably located directly on the connecting longitudinal edge 5 .

Der Kontur-Ausschnitt 40 der Verbindungsquerränder 6 ist zwischen den Verbindungslängsrändern 5 vorgesehen. Der Kontur-Ausschnitt 40 entspricht etwa der Kontor der Verschlusskappe 11, damit eine feste und dichte Lötverbindung erzielt wird. Die Kontur des Ausschnitts hängt somit von der gewählten Kontur der Verschlusskappe 11 ab. Wie insbesondere die Fig. 2, in Verbindung mit den Fig. 9 und 10, zeigt, ist der Kontur-Ausschnitt 40 im Ausführungsbeispiel so ausgebildet, dass die beiden Verbindungslängsränder 5 etwas über den restlichen Verbindungsquerrand 6 des Rohrbodens 3 ragen. Die überragenden Verbindungslängsränder besitzen in den Fig. 2, 9 und 10 das Bezugszeichen 51. Zum Kontur - Ausschnitt 40 gehört im Ausführungsbeispiel ferner beidseitig je eine Abstufung 50, deren Größe etwa der Blechdicke der Sammelkästen 7, bzw. der Blechdicke der Längswände 8, 9 entspricht. Die überstehenden Verbindungslängsränder 51 nehmen somit je einen Vorsprung 20 zwischen sich und dem Rand 14 des Verschlusskappe 11 auf. Bei Rohrböden 3, die eine etwas größere Blechdicke besitzen, kann die Verbindung zwischen deren Verbindungsquerrand 5 und der Verschlusskappe 11, wie in der Fig. 12 gezeigt, ohne Flansch ausgebildet sein. Die Fig. 13 und 14 hingegen zeigen einen Flansch 41, wobei in der Fig. 13 der Flansch nach unten gerichtet ist und in der Fig. 14 nach oben, um auch bei dünneren Rohrböden 3 eine feste und dichte Lötverbindung zu schaffen.The contour cutout 40 of the connecting transverse edges 6 is provided between the connecting longitudinal edges 5 . The contour cutout 40 corresponds approximately to the Kontor the cap 11 so that a solid and tight solder joint is achieved. The contour of the cutout thus depends on the selected contour of the closure cap 11 . As shown particularly in FIG. 2, in conjunction with FIGS. 9 and 10 , shows the contour cutout 40 is formed in the exemplary embodiment so that the two connecting longitudinal edges 5 slightly above the remaining connecting transverse edge 6 of the tube sheet 3 protrude. The protruding connecting longitudinal edges have the reference numeral 51 in FIGS. 2, 9 and 10. In addition to the contour cutout 40 in the exemplary embodiment, a graduation 50 , whose size approximately corresponds to the sheet thickness of the collecting boxes 7 , or the sheet thickness of the longitudinal walls 8 , 9 , also belongs on both sides. The projecting connecting longitudinal edges 51 thus each receive a projection 20 between them and the edge 14 of the closure cap 11 . In tube sheets 3 , which have a slightly larger sheet thickness, the connection between the connecting transverse edge 5 and the closure cap 11 , as shown in FIG. 12, be formed without a flange. 13 and 14, however, show a flange 41 , wherein in Fig. 13, the flange is directed downward and in Fig. 14 upwards to create a solid and tight solder joint even with thinner tube sheets 3 .

Am Rand 14 der Verschlusskappe 11 ist ein Ausschnitt 16 vorgesehen, in den eine Lasche 17 an der Querwand des Sammelkastens 7 hineingebogen wurde, um eine provisorische Halterung des Wärmeaustauschers in der Herstellungsphase zu schaffen. Der in Fig. 11 dargestellte Teil - Längsschnitt verläuft genau durch die erwähnten Mittel zum Fixieren 15 und zeigt die Lasche 17 im bereits umgebogenen Zustand.At the edge 14 of the closure cap 11 , a cutout 16 is provided, into which a flap 17 has been bent on the transverse wall of the collecting box 7 in order to provide a provisional holding of the heat exchanger in the production phase. The partial longitudinal section shown in FIG. 11 runs exactly through the mentioned means 15 for fixing and shows the tab 17 in the already bent state.

Der Montageprozess des Wärmeaustauschers ist in dem beschriebenen Ausführungsbeispiel folgendermaßen: Die Flachrohre 1 werden abwechselnd mit den Wellrippen 2 zum sogenannten Rippen - Rohr - Block zusammengesetzt. Danach werden die Seitenteile 10 mit den Verschlusskappen 11 angesetzt. Anschließend wird an beiden Enden der Flachrohre 1 je ein Rohrboden 3 aufgezogen, wonach die Enden der Flachrohre 1 in den Öffnungen 4 der Rohrböden 3 stecken. Schließlich werden die Sammelkästen 7 auf die Rohrböden 3 gesetzt, wobei die Vorsprünge 20 jeweils in die Öffnungen 30 eingeschoben werden. Die Sammelkästen 7 sind dadurch in ihrer Längsrichtung festgelegt. Gleichzeitig wird damit ein Anpressen der Verbindungslängsränder 5 des Rohrbodens 3 an die Längswände 8, 9 des Sammelkastens 7 erreicht. Danach kommen die erwähnten Mittel 15 zum Fixieren zum Einsatz, die vorzugsweise in Form der ebenfalls erwähnten Laschen 17 ausgebildet sind, die in den Ausschnitt 16 am Rand 14 der Verschlusskappe 11 gebogen werden. Der Wärmeaustauscher ist somit eine sich selbst haltende Einheit, die für den Lötprozess vorbereitet werden kann.The assembly process of the heat exchanger is in the described embodiment as follows: The flat tubes 1 are alternately assembled with the corrugated fins 2 to the so-called rib-tube block. Thereafter, the side parts 10 are attached to the caps 11 . Subsequently, a tube plate 3 is raised at each end of the flat tubes 1 , after which the ends of the flat tubes 1 are inserted into the openings 4 of the tubesheets 3 . Finally, the collecting boxes 7 are placed on the tubesheets 3 , wherein the projections 20 are respectively inserted into the openings 30 . The headers 7 are thereby fixed in their longitudinal direction. At the same time a pressing of the connecting longitudinal edges 5 of the tube sheet 3 to the longitudinal walls 8 , 9 of the collecting tank 7 is achieved. Thereafter, the mentioned means 15 are used for fixing, which are preferably formed in the form of the tabs 17 also mentioned, which are bent into the cutout 16 at the edge 14 of the cap 11 . The heat exchanger is thus a self-contained unit that can be prepared for the soldering process.

Die Fig. 7 unterscheidet sich von der Fig. 8 dadurch, dass die Fig. 7 einen Schnitt im Bereich eines Flachrohres 1 zeigt und die Fig. 8 einen anderen Schnitt im Bereich der Vorsprünge 20. Die Fig. 5 und 6 unterscheiden sich ebenfalls nur wegen der unterschiedlichen Schnittebenen.FIG. 7 differs from FIG. 8 in that FIG. 7 shows a section in the region of a flat tube 1 and FIG. 8 shows another section in the region of the projections 20 . FIGS. 5 and 6 also differ only because of the different cutting planes.

In den Figuren wurde kein kompletter Wärmeaustauscher abgebildet, weil der Fachmann, an den sich eine Anmeldung gewöhnlich wendet, die nicht gezeigten Teile ohne weiteres zu einem vollständigen Wärmeaustauscher ergänzen wird. Ein wärmetauschendes Medium tritt beispielsweise in den in den Fig. 1 und 2 gezeigten Stutzen 70 in den Sammelkasten 7 ein und verteilt sich auf die Flachrohre 1, um diese zu durchströmen. Ein identischer oder ähnlicher Sammelkasten 7 befindet sich auf der einen nicht gezeigten Seite (in Längsrichtung der Flachrohre) des Wärmeaustauschers und ein weiterer nicht gezeigter Stutzen ist entweder am gezeigten oder am nicht gezeigten Sammelkasten 7 angeordnet, um das wärmetauschende Medium abzuführen. Kühlluft strömt durch die Wellrippen 2 und steht mit dem erwähnten Medium in wärmetauschender Beziehung. Ferner ist lediglich ein Seitenteil 10 gezeigt, wobei sich versteht, dass ein zweites Seitenteil auf der zweiten nicht gezeigten Seite (in Querrichtung zu den Flachrohren) vorhanden ist, das wenigstens bezüglich der hier beschriebenen Merkmale identisch ist.No complete heat exchanger has been illustrated in the figures, because those skilled in the art, to whom an application will commonly refer, will readily supplement the parts not shown to a complete heat exchanger. A heat exchanging medium into the collecting box 7 occurs, for example in the positions shown in Figs. 1 and 2 nozzles 70, and distributed to the flat tubes 1 to pass through to it. An identical or similar collection box 7 is located on the one side not shown (in the longitudinal direction of the flat tubes) of the heat exchanger and another not shown nozzle is arranged either on the shown or not shown collection box 7 to dissipate the heat exchanging medium. Cooling air flows through the corrugated fins 2 and is in heat exchanging relationship with the mentioned medium. Further, only one side member 10 is shown, it being understood that a second side member is present on the second side not shown (transverse to the flat tubes) that is identical at least with respect to the features described herein.

Im Ausführungsbeispiel aus der Fig. 15 sind die Verschlusskappen 11 als Einzelteile ausgebildet, wie es auch in der nicht vorveröffentlichten Anmeldung vorgesehen worden ist. Auch bei solchen Wärmeaustauschern wird in den Verbindungsquerrändern 6 der Rohrböden 3 ein Kontur - Ausschnitt 40 vorgesehen. Ferner sind an den Rändern der Längswände 8, 9 der Sammelkästen 7 Vorsprünge 20 vorhanden, die in korrespondierende Öffnungen 30 in den Rohrböden 3 eingeführt werden. Die erwähnten Öffnungen 30 sind in der Fig. 15 nicht erkennbar, weswegen diesbezüglich auf die Fig. 9 verwiesen wird. Die Mittel zum Fixieren 15, die in diesem Ausführungsbeispiel eher erforderlich sind als in dem ersten Ausführungsbeispiel, bestehen aus an dem Rand 14 der Verschlusskappe 11 ausgebildeten Klammern.In the embodiment of FIG. 15, the closure caps 11 are formed as individual parts, as has also been provided in the non-prepublished application. Even with such heat exchangers, a contour cutout 40 is provided in the connecting transverse edges 6 of the tubesheets 3 . Further, at the edges of the longitudinal walls 8 , 9 of the manifolds 7 projections 20 are provided, which are inserted into corresponding openings 30 in the tube sheets 3 . The mentioned openings 30 are not recognizable in FIG. 15, for which reason reference is made to FIG. 9 in this regard. The fixing means 15 , which are required in this embodiment rather than in the first embodiment, consist of clips formed on the edge 14 of the closure cap 11 .
