Abstract
Die Erfindung betrifft einen mechanisch gefügten Wärmetauscher (1), insbesondere einen luftgekühlten Kühlmittelkühler, mit mehreren parallel zueinander angeordneten Rohren (2; 2¶0¶, 2¶1¶, 2¶2¶), wobei die Rohre (2; 2¶0¶, 2¶1¶, 2¶2¶) in ihrer Reihe versetzt zueinander angeordnet sind.The invention relates to a mechanically joined heat exchanger (1), in particular an air-cooled coolant radiator, with a plurality of mutually parallel tubes (2; 2¶0¶, 2¶1¶, 2¶2¶), wherein the tubes (2; 2¶0 ¶, 2¶1¶, 2¶2¶) are offset in their series.
Description
Die Erfindung betrifft einen mechanisch gefügten Wärmetauscher, insbesondere einen Kühlmittelkühler, wie er bei Kraftfahrzeugen verwendet wird, gemäß dem Oberbegriff des Anspruches 1.The The invention relates to a mechanically joined heat exchanger, in particular a Coolant cooler, like it is used in motor vehicles, according to the preamble of the claim 1.
Bei mechanisch gefügten Kühlmittelkühlern, bei denen die einzelnen Teile des Wärmetauschers wie Rohre, Rippen, Rohrböden und Sammel- oder Wasserkästen nicht stoffschlüssig, sondern mit mechanischen Mitteln gefügt werden, werden üblicherweise die Rohre mechanisch gegenüber den Rippen und den Rohrböden aufgeweitet, so dass nach dem Zusammenfügen eine hinreichende Pressung erzielt wird, welche bei der Rohr/Bodenverbindung die erforderliche Dichtheit und bei der Rohr/Rippenverbindung den erforderlichen thermischen Kontakt herstellt. Bei derart mechanisch gefügten Kühlmittelkühlern, insbesondere bei Kühlmittelkühlern geringer Bautiefe, kommt es auf Grund mechanischer Beanspruchung, bspw. bei Vibrationen, gelegentlich zu temporären Undichtheiten, die durch Relativbewegungen der Rohre in ihrer Gummidichtung zum Boden des Kühlmittelkühlers hervorgerufen werden. Ein derartiger mechanisch gefügter Wärmetauscher lässt somit noch Wünsche offen, insbesondere in Hinblick auf die Dichtheit bei mechanischer Beanspruchung.at mechanically joined Coolant coolers, at which the individual parts of the heat exchanger like Pipes, ribs, tube sheets and collection or water boxes not cohesively, but be joined by mechanical means, are usually mechanically facing the pipes the ribs and tubesheets expanded, so that after joining a sufficient pressure is achieved, which in the pipe / floor connection the required Tightness and in the tube / rib connection the required thermal Contact establishes. In such mechanically joined coolant radiators, in particular coolant radiators of small overall depth, is it due to mechanical stress, for example, in vibration, occasionally too temporary Leakages caused by relative movement of the tubes in their rubber seal caused to the bottom of the coolant cooler become. Such a mechanically joined heat exchanger thus leaves still wishes open, in particular with regard to the tightness in mechanical Stress.
Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, einen mechanisch gefügten Wärmetauscher zur Verfügung zu stellen, der auch bei mechanischer Beanspruchung dicht ist. Diese Aufgabe wird gelöst durch einen Wärmetauscher mit den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.outgoing From this prior art, it is an object of the invention to provide a mechanically joined heat exchangers to disposal to provide that is tight even under mechanical stress. These Task is solved through a heat exchanger with The features of claim 1. Advantageous developments are Subject of the dependent claims.
Erfindungsgemäß ist ein mechanisch gefügter Wärmetauscher, insbesondere ein luftgekühlter Kühlmittelkühler, vorgesehen, mit mehreren parallel zueinander angeordneten Rohren bei dem die Rohre in ihrer Reihe versetzt zueinander angeordnet sind. Dabei kommt insbesondere ein einfacher Versatz, d.h. die Mittelachsen der Rohre bilden zwei parallel zueinander angeordnete Ebenen, wobei Mittelachsen benachbarter Rohre in unterschiedlichen Ebenen angeordnet sind, oder ein zweifacher Versatz, d.h. die Mittelachsen der Rohre bilden drei parallel zueinander angeordnete Ebenen, wobei vorzugsweise jedes Rohr der mittleren Reihe benachbart zu einem Rohr der vorderen und der hinteren Reihe angeordnet ist, in Frage. Durch das Vorsehen eines Versatzes der Rohre, insbesondere benachbarter Rohre, wird der Wärmetauscher stabilisiert, d.h. Schwingungen und Motorbewegungen, die sich über Schläuche oder Befestigungselemente auf den Wärmetauscher übertragen und Biegebeanspruchungen im Kasten/Boden-Netz erzeugen, erzeugen auf Grund der größeren Steifigkeit des Wärmetauschers auch bei geringen Bautiefen geringere oder keine oder nur minimale Verformungen, so dass eine Dichtheit sicher gewährleistet werden kann.According to the invention is a mechanically linked Heat exchanger, in particular an air-cooled coolant cooler, provided, with a plurality of mutually parallel tubes in which the Pipes in their row are offset from one another. there In particular, a simple offset, i. the central axes the tubes form two mutually parallel planes, wherein Center axes of adjacent tubes arranged in different planes are, or a double offset, i. the central axes of the tubes form three mutually parallel planes, preferably each tube of the middle row adjacent to a tube of the front and the rear row is arranged, in question. By providing an offset of the tubes, in particular adjacent tubes, is the heat exchanger stabilized, i. Vibrations and motor motions, which are connected via hoses or Transfer fasteners to the heat exchanger and generate bending stresses in the box / floor mesh due to the greater rigidity the heat exchanger too at low depths less or no or only minimal deformations, so that a tightness can be safely ensured.
Beim Wärmetauscher handelt es sich vorzugsweise um einen einreihigen Wärmetauscher, insbesondere um einen Wärmetauscher geringer Bautiefe.At the heat exchangers it is preferably a single-row heat exchanger, in particular around a heat exchanger low depth.
Der Versatz der Rohre ist vorzugsweise größer als Null, insbesondere größer als das 0,2-fache, insbesondere bevorzugt größer als das 0,5-fache der Rohrbreite in normaler Luftströmungsrichtung, und beträgt maximal das einfache, vorzugsweise maximal das 0,6-fache der Rohrbreite in normaler Luftströmungsrichtung.Of the Offset of the tubes is preferably greater than zero, in particular greater than 0.2 times, more preferably greater than 0.5 times the tube width in the normal air flow direction, and is at most the simple, preferably a maximum of 0.6 times the tube width in the normal air flow direction.
Insbesondere bei einem zweifachen Versatz beträgt der Versatz der Rohre minimal das 0,2 und maximal das 0,6-fache der Rohrbreite in normaler Luftströmungsrichtung.Especially with a two-time offset, the offset of the tubes is minimal 0.2 and a maximum of 0.6 times the pipe width in the normal air flow direction.
Der Versatz bei einem zweifachen Versatz ist vorzugsweise in Luftströmungsrichtung gleich groß wie der Versatz entgegen der Luftströmungsrichtung.Of the Offset at twice offset is preferably in the airflow direction the same size as the offset against the direction of air flow.
Bevorzugt ist der Durchmesser der Rohre in Luftströmungsrichtung größer oder gleich (Rundrohr) dem Durchmesser des Rohres senkrecht zur Luftströmungsrichtung.Prefers is the diameter of the tubes in the air flow direction greater or equal (round tube) the diameter of the tube perpendicular to the direction of air flow.
