Abstract
Description
Die Erfindung betrifft eine elastomere Dichtung, wie Dichtring, für einen Wärmetauscher, insbesondere für ein Kraftfahrzeug, mit den Merkmalen des Oberbegriffs des Anspruchs 1, sowie einen Wärmetauscher mit einer solchen Dichtung.The The invention relates to an elastomeric seal, such as a sealing ring, for a Heat exchanger, especially for a motor vehicle, having the features of the preamble of the claim 1, and a heat exchanger with such a seal.

derartige Dichtung ist beispielsweise aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Dichtung für einen Wärmetauscher, insbesondere für Kraftfahrzeuge, anzugeben, die bei der Montage besonders unkritisch hinsichtlich geometrischer Toleranzen sowie der Handhabung ist.Of the Invention is based on the object, a seal for a Heat exchanger, especially for Motor vehicles, specify that during assembly particularly uncritical in terms of geometric tolerances and handling.
Diese Aufgabe wird erfindungsgemäß gelöst durch eine elastomere Dichtung, wie Dichtring, mit den Merkmalen des Anspruches 1. Diese Dichtung für einen Wärmetauscher, insbesondere für Kraftfahrzeuge, ist als einstöckiges Spritzteil ausgebildet und für eine Klemmverbindung zwischen Wasserkasten und Rohrboden vorgesehen, wobei die Dichtung zunächst in eine umlaufende Nut des Rohrbodens eingelegt und anschließend zwischen Flansch des Wasserkastens und Rohrboden eingespannt wird. Die Dichtung, deren Kontur oder Grundriss entsprechend der Form des Wärmetauschers rechteckig ist, weist zumindest eine umlaufende Vertiefung in ihrer Oberfläche auf. Die zumindest eine umlaufende Vertiefung gestattet den Einsatz der Dichtung in einem weiten geometrischen Toleranzbereich. Beim Quetschen der Dichtung steigen die von der Dichtung auf die umgebenden Bauteile ausgeübten Kräfte im Vergleich zu Dichtungen mit rundem oder ovalem Querschnitt nur relativ langsam an.This The object is achieved by an elastomeric seal, such as a sealing ring, with the features of the claim 1. This seal for a heat exchanger, especially for Motor vehicles, is as single-storey Molded part and for a clamping connection between water tank and tube sheet provided being the seal first inserted in a circumferential groove of the tubesheet and then between Flange of the water box and tube sheet is clamped. The seal, their contour or layout according to the shape of the heat exchanger is rectangular, has at least one circumferential recess in its surface. The at least one circumferential recess allows the use of Seal in a wide geometric tolerance range. When squeezing the seal rises from the seal to the surrounding components exerted personnel compared to seals with round or oval cross-section only relatively slow.
Eine bevorzugte Ausführungsform der erfindungsgemäßen Dichtung ist durch einen symmetrischen, insbesondere sternförmigen Querschnitt gekennzeichnet. Dadurch ist bereits bei geringer Verformung der Dichtung im eingebauten Zustand eine sehr gute Dichtwirkung gegeben. Aufgrund der rotationssymmetrischen Ausbildung des Dichtungsquerschnitts ist die Dich tung weit weniger empfindlich gegenüber einer Verdrehung oder Verdrillung als eine Dichtung mit nicht rotationssymmetrischem, beispielsweise ovalem Querschnitt. Unabhängig hiervon ist eine eventuelle Verdrillung der Dichtung aufgrund deren deutlich ausgeprägter Oberflächenstruktur sehr leicht optisch erkennbar und damit vermeidbar.A preferred embodiment the seal according to the invention is by a symmetrical, in particular star-shaped cross-section characterized. This is already at low deformation of Seal when installed given a very good sealing effect. Due to the rotationally symmetrical design of the sealing cross section the seal is far less sensitive to twisting or twisting as a seal with non-rotationally symmetric, for example oval cross-section. Independently This is a possible twist of the seal due to their much more pronounced Surface texture very much easily visually recognizable and thus avoidable.
Eine weitgehend gleichförmige, einer Dichtung mit rundem Querschnitt vergleichbare Anlage der Dichtungsoberfläche an umgebenden Bauteilen ist erzielbar mit einem sternförmigen Dichtungsquerschnitt mit einer Vielzahl von Vertiefungen, während ein sternförmiger Dichtungsquerschnitt mit einer geringeren Anzahl an Vertiefungen größere Verformungsreserven aufweist, jedoch in größerem Maße von der Einbaulage abhängige Eigenschaften, insbesondere Dichtungs- und Elastizitätseigenschaften, hat. Ein guter Kompromiss ist erzielbar mit einem sternförmigen Dichtungsquerschnitt mit zehn an der Dichtungsoberfläche angeordneten Vertiefungen.A largely uniform, a seal with a round cross-section comparable conditioning of the sealing surface to surrounding Components can be achieved with a star-shaped sealing cross-section with a multitude of depressions, while a star-shaped sealing cross-section having larger deformation reserves with a smaller number of wells, however, to a greater extent by the Installation position dependent Properties, in particular sealing and elasticity properties, has. A good compromise can be achieved with a star-shaped sealing cross-section with ten at the sealing surface arranged depressions.
Die Vertiefungen an der Dichtungsoberfläche unterstützen die Nachgiebigkeit der Dichtung, wobei im Allgemeinen jedoch ein vollständiges Umbiegen von zwischen benachbarten Rillen liegenden Erhebungen, allgemein Stege genannt, im eingebauten Zustand nicht beabsichtigt ist. Um sowohl eine ausreichende Elastizität als auch eine ausreichende Stabilität der Dichtung zu gewährleisten, beträgt der innere Radius des Dichtungsquerschnitts, d.h. der durch die Rillen gegebene Radius vorzugsweise mindestens 65% und höchstens 90% des durch die Stege gegebenen äußeren Radius des Dichtungsquerschnitts.The Recesses on the sealing surface support the resilience of the Seal, but in general, a complete bending of between elevations lying adjacent grooves, commonly called webs, in the installed state is not intended. To provide both a sufficient elasticity as well as to ensure sufficient stability of the seal is the inner radius of the seal cross-section, i. the one by the Grooves given radius preferably at least 65% and at most 90% of the given by the webs outer radius of the sealing cross-section.
Nach einer bevorzugten Ausgestaltung der Erfindung werden zwei Rillen durch einen abgerundeten Steg voneinander getrennt. Hierdurch sind beispielsweise im Vergleich zu einer ausgeprägt zackigen Sternform größere Anlageflächen der Dichtung an umgebenden Bauteilen erzielbar.After A preferred embodiment of the invention are two grooves separated by a rounded bridge. Hereby are For example, in comparison to a pronounced jagged star shape larger contact surfaces of Seal achievable on surrounding components.
Die
Montage, insbesondere automatisierte Montage, der Dichtung ist nach
einer bevorzugten Weiterbildung durch eine Spannhilfe erleichtert.
Derartige Spannhilfen an den Ecken der Dichtung sind beispielsweise
aus der
In einer bevorzugten Weiterbildung wird der erfindungsgemäße Dichtring in einem Wärmetauscher mit zumindest einem Wasserkasten, zumindest einem Rohrboden und einer Klemmverbindung zwischen dem zumindest einen Wasserkasten und dem zumindest einen Rohrboden eingesetzt, indem er in eine umlaufende Nut des Rohrbodens eingelegt und zwischen einem Flansch des Wasserkastens und dem Rohrboden eingespannt wird. Hierdurch wird die Klemmverbindung zwischen dem Wasserkasten und dem Rohrboden abgedichtet.In A preferred development of the sealing ring according to the invention in a heat exchanger with at least one water tank, at least one tubesheet and a clamping connection between the at least one water tank and the at least one tubesheet used by being in a circumferential Groove of the tubesheet inserted and between a flange of the water box and the tube sheet is clamped. This will cause the clamp connection sealed between the water box and the tube sheet.
Es besteht überdies die Möglichkeit, den erfindungsgemäßen Dichtring in einem beliebigen Wärmetauscher allein oder in Verbindung mit zumindest einem weiteren Dichtring zu verwenden, wobei der zumindest eine weitere Dichtring ebenfalls ein erfindungsgemäßer Dichtring oder ein Dichtring nach dem Stand der Technik sein kann.It exists moreover the possibility, the sealing ring according to the invention in any heat exchanger alone or in conjunction with at least one other sealing ring to use, wherein the at least one further sealing ring also an inventive sealing ring or may be a sealing ring according to the prior art.
