Abstract
Elastomere Dichtung für einen Wärmetauscher, insbesondere für Kraftfahrzeuge, wobei der Wärmetauscher mit einem Wasserkasten und einem Rohrboden (2) versehen ist, mit einer rechteckigen Kontur, die als einstückiges Spritzteil ausgebildet ist und in eine umlaufenden Nut des Rohrbodens unter Vorspannung einlegbar ist, wobei an den Ecken der Dichtung (1) jeweils eine Spannhilfe (6) angeformt ist, die in Eckschlitzen (7) eines Randes (15) des Rohrbodens einhängbar ist.Elastomeric seal for a heat exchanger, in particular for motor vehicles, wherein the heat exchanger is provided with a water box and a tube bottom (2), with a rectangular contour which is formed as a one-piece molded part and in a circumferential groove of the tubesheet under bias is inserted, wherein The corners of the seal (1) in each case a clamping aid (6) is formed, which is in corner slots (7) of an edge (15) of the tube sheet can be suspended.
Description
Die Erfindung betrifft eine elastomere Dichtung für einen Wärmetauscher, insbesondere für Kraftfahrzeuge.The The invention relates to an elastomeric seal for a heat exchanger, in particular for motor vehicles.
Stand der TechnikState of the art
Aus
der
Die
Nachteilig ist bei diesem Stand der Technik, dass die Dichtung bei dem Zusammenfügen der beiden Teile zwischen dem Flansch und dem umbiegbaren Randbereich verrutschen kann. Dies ist insbesondere dann der Fall, wenn der Flansch, der umbiegbare Randbereich oder beide konkav oder konvex verformt sind. Beim Zusammenfügender Teile kann sich die Dichtung in der Nut verschieben, wobei sie sich aufwirft, so dass der Wärmetauscher nach dem Zusammenfügen der Teile undicht ist.adversely is in this prior art that the seal in the assembly of the two parts between the flange and the bendable edge region can slip. This is especially the case when the Flange, the bendable edge area or both concave or convex are deformed. When joining Parts may shift the seal in the groove, leaving them poses, leaving the heat exchanger after joining the parts is leaking.
Aufgabenstellungtask
Aufgabe der vorliegenden Erfindung ist es, die Dichtung so zwischen dem Flansch und dem umbiegbaren Randbereich einzulegen, dass sie sich beim Zusammenfügen der Teile nicht mehr aufwerfen kann.task the present invention is so between the gasket Flange and the bendable edge area insert that they Put together the parts can no longer raise.
Zur Lösung der Aufgabe wird eine elastomere Dichtung gemäß dem Anspruch 1 vorgeschlagen, welche unter Vorspannung in den Rohrboden eingelegt wird. Der Vorteil dieser Anordnung ist, dass sich bei einem Verschieben eines Teiles der Dichtung diese nicht mehr aufwerfen wird, sondern dass sie sich in sich zusammenzieht, sich also verkürzt. Diese so verkürzte Dichtung verbleibt exakt an ihrer vorbestimmten Einbaulage. Außerdem können bei dieser Ausgestaltung der Dichtung auch Fertigungstoleranzen ausgeglichen werden. Die notwendige Vorspannung wird nach Anspruch 4 und Anspruch 24 zweckmäßigerweise dadurch erzeugt, dass die Dichtung ein gewisses Untermaß aufweist, wobei der innere Umfang der Dichtung bis zu 15%, vorzugsweise 2% bis 3% geringer als der äußere Umfang der Nutwandung des Rohrbodens ist. Insbesondere sind die Langseiten der Dichtung deutlich kürzer als die Langseiten der Nutwandung.to solution The object is proposed an elastomeric seal according to claim 1, which loaded under bias in the tubesheet. The advantage of this Arrangement is that when moving a part of the This seal will no longer pose, but that they are in contracts, so shortened. This so shortened seal remains exactly at its predetermined mounting position. In addition, at this design of the seal also compensated for manufacturing tolerances become. The necessary bias is according to claim 4 and claim 24 expediently generated by the fact that the seal has a certain undersize, wherein the inner circumference of the seal up to 15%, preferably 2% to 3% less than the outer circumference the groove wall of the tube sheet is. In particular, the long sides the seal significantly shorter as the long sides of the groove wall.
Nach Anspruch 1 sind an den vier Ecken der Dichtung, die eine im wesentlichen rechteckige Kontur aufweist, Spannhilfen angeformt. Sie dienen der vereinfachten Montage der Dichtung in dem Rohrboden. Besonders vorteilhaft ist die Auslegung der Spannhilfen mit Ösen, da diese auch von Handhabungsautomaten gegriffen und die Dichtung unter Vorspannung in den Rohrboden eingesetzt werden kann. Zur weiteren Vereinfachung ist der Rohrboden an diese Ausführungsform der Dichtung angepaßt. So weisen seine Ecken Eckschlitze auf, in die die Dichtung mit ihren Spannhilfen eingehängt ist. Dabei wird einerseits die Montage der Dichtung erleichtert, insbesondere auch die automatische Montage, andererseits wird die vorgespannte Dichtung sicher an ihrem Einbauort festgehalten. Ein weiterer Vorteil besteht darin, daß die Dichtung am Innenumfang des umbiegbaren Randes anliegt, da üblicherweise auch der Wasserkasten, der auf die Dichtung aufgesetzt wird, mit dem Innenumfang des umbiegbaren Randes in Kontakt gebracht wird. Beim anschließenden Zusammenpressen des Rohrbodens und des Wasserkastens verbleibt die Dichtung in ihrer vorherbestimmten Lage zwischen diesen beiden Teilen, wobei ein Verschieben oder Verwerfen der Dichtung vermieden wird. Der Wasserkasten wird durch Umbiegen des umbiegbaren Randes auf dem Rohrboden fixiert.To Claim 1 are at the four corners of the seal, which is a substantially has rectangular contour, formed clamping aids. They serve the simplified Assembly of the seal in the tubesheet. Is particularly advantageous the design of the clamping aids with eyelets, as these also of handling machines gripped and the gasket inserted under pretension in the tubesheet can be. To further simplify the tubesheet to this embodiment adapted to the seal. So Its corners have corner slots in which the seal with their Clamping aids mounted is. On the one hand, the assembly of the seal is facilitated, in particular also the automatic assembly, on the other hand, the prestressed Seal securely held in place. Another advantage is that the Seal rests against the inner circumference of the bendable edge, as usual also the water box, which is placed on the seal, with the inner periphery of the bendable edge is brought into contact. During the subsequent compression the tube bottom and the water box, the seal remains in her predetermined position between these two parts, with a shift or discarding the seal is avoided. The water tank is Fixed by bending the bendable edge on the tubesheet.
Nach Anspruch 9 sind an die Ösen der Spannhilfen Markierungsfähnchen angeformt. Sie dienen der Identifizierung der Dichtung bei der Montage, so kann hier z. B. eine Teilenummer aufgebracht sein, und ebenso dem Sortieren bei einem Recycling, indem hier eine Stoffkennzeichnung aufgebracht ist. Außerdem kann auch im eingebauten Zustand überprüft werden, welche Dichtung eingebaut worden ist und ob sie seitenrichtig eingelegt wurde, da die Markierungsfähnchen mitsamt den Spannhilfen auch im montierten Zustand aus den Eckschlitzen des Rohrbodens herausragen.To Claim 9 are to the eyelets the clamping aids mark flag formed. They serve to identify the seal during assembly, so here z. For example, a part number may be applied and as well sorting in a recycling, by here a substance identification is applied. Furthermore can also be checked in the installed state, which seal has been installed and whether it was inserted the right way, since the flags together with the clamping aids in the assembled state from the corner slots of the Protruding tube bottom.
Nach Anspruch 23 sind in die Nutwandung des Rohrbodens Arretiernocken eingeprägt. Unter diesen Arretiernocken wird die vorgespannte Dichtung in der Nut des Rohrbodens fixiert. Vorteilhaft an dieser Art der Ausgestaltung ist, dass vorhandene Dichtungen weiterverwendet werden können. Außerdem weist der umbiegbare Rand keine Eckschlitze auf.To Claim 23 are in the groove wall of the tube plate locking cams imprinted. Among these locking cams, the preloaded seal in the Groove of the tube bottom fixed. Advantageous to this type of embodiment is that existing seals can continue to be used. In addition, points the bendable edge has no corner slots.
