Description
Die Erfindung betrifft einen Wärmeübertrager in Ganzmetall-, vorzugsweise Ganzaluminium-Bauweise insbesondere nach dem Oberbegriff des Patentanspruches 1.The The invention relates to a heat exchanger in all-metal, preferably all-aluminum construction in particular according to the preamble of claim 1.
Ganzmetallwärmeübertrager, insbesondere gelötete Aluminiumwärmeübertrager werden als Kühlmittelkühler oder Ladeluftkühler für Kraftfahrzeuge eingesetzt. Der Vorteil dieser Wärmeübertrager ist, dass sie sortenrein und daher leicht recyclefähig sind. Durch die DE-A 195 43 986 der Anmelderin wurde ein gelöteter Aluminiumwärmeübertrager mit Flachrohren bekannt, deren Enden zu einem rechteckförmigen Querschnitt aufgeweitet sind. Die Rohrenden weisen Längsseiten und Schmalseiten auf, wobei die Längsseiten dicht aneinander liegen und miteinander verlötet sind, während die Schmalseiten Außenflächen bilden, die mit den Innenflächen eines Sammelkastens verbunden sind. Der Sammelkasten weist ein etwa U-förmiges Profil (U-Profil) mit seitlichen Schenkeln auf, welche die Schmalseiten der Rohrenden umfassen. Durch diese Bauweise entfällt ein konventioneller Rohrboden mit den entsprechenden Rohr/Rohrbodenverbindungen. Alternativ zu dem U-Profil ist durch diese Druckschrift auch ein zylinderförmiger Sammelbehälter bekannt, welcher parallele Kragen zur Anlage an den Schmalseiten der Rohrenden aufweist. Problematisch bei dieser Bauweise sind die Lötverbindungen, wenn der Wärmeübertrager während des Betriebes mit Innendruck beaufschlagt wird. Insbesondere im Bereich der Lötverbindungen zwischen den Schmalseiten der Rohrenden und den Schenkeln des Sammelkastens können sich Risse in der Lötnaht bilden, insbesondere wenn das Sammelkastenprofil nicht nachgiebig ausgebildet ist und sich zusätzlich Biegespannungen im Lötnahtbereich ergeben.All-metal heat exchanger, especially soldered Aluminum heat exchangers be as coolant radiator or Intercooler for motor vehicles used. The advantage of this heat exchanger is that they are sorted and therefore easily recyclable. By DE-A 195 Applicant's 43,986 became a brazed aluminum heat exchanger known with flat tubes whose ends to a rectangular cross-section are widened. The pipe ends have long sides and narrow sides on, with the long sides close to each other and are soldered together, while the narrow sides form outer surfaces, those with the inner surfaces a collecting box are connected. The collection box has an approximately U-shaped Profile (U-profile) with side legs on which the narrow sides the pipe ends include. This construction eliminates one conventional tube sheet with the corresponding tube / tube bottom connections. Alternative to the U-profile this document also discloses a cylindrical collecting container, which parallel collar to rest on the narrow sides of the pipe ends having. The problem with this design are the solder joints, if the heat exchanger while the operation is subjected to internal pressure. Especially in the Range of solder joints between the narrow sides of the pipe ends and the legs of the collecting tank can Cracks in the soldered seam form, especially if the collection box profile is not yielding is formed and in addition Bending stresses in the solder seam area result.
Es ist Aufgabe der vorliegenden Erfindung, bei einem Wärmeübertrager der eingangs genannten Art die Haltbarkeit der Lötverbindungen, insbesondere im Bereich der Rohrenden zu verbessern.It Object of the present invention, in a heat exchanger the type mentioned the durability of the solder joints, in particular to improve in the area of the pipe ends.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Erfindungsgemäß ist vorgesehen, dass das U-Profil des Sammelkastens spannungsoptimiert ausgebildet ist, wobei die erfindungsgemäße Gestaltung einen Rundbogen zwischen zwei geraden Schenkeln des U-Profiles vorsieht. Dabei gehen die Schenkel vorzugsweise mit einer stetig wachsenden Krümmung in den Rundbogen über, der einen oberen symmetrisch angeordneten Scheitelpunkt aufweist. Durch diese Gestaltung ergibt sich in den Querschnitten des Sammelkastens eine günstige Spannungsverteilung, weil das Profil des Sammelkastens aufgrund der bogenförmigen Ausbildung nachgeben kann. Damit werden auch ungünstige Biegespannungen von den Lötverbindungen ferngehalten. Insgesamt ergibt sich durch diese optimierte Profilgestaltung eine dauerhafte Lötverbindung, bei welcher eine Rissbildung durch ungünstige Beanspruchung vermieden wird.These The object is solved by the features of claim 1. According to the invention, it is provided that the U-profile of the header box formed voltage optimized is, wherein the inventive design a round arch between two straight legs of the U-profile provides. The legs preferably go with a steadily growing curvature into the arch around, having an upper symmetrically arranged vertex. This design results in the cross sections of the header box a favorable Stress distribution, because the profile of the header due to the arcuate training can yield. This also unfavorable bending stresses of the solder joints kept away. Overall results from this optimized profile design a permanent solder joint, in which cracking caused by unfavorable stress becomes.
Bei einem vorteilhaften Ausführungsbeispiel der Erfindung wird eine Unstetigkeit in der Belastung, wie Kraft, im Übergang von einer Materialstärke auf eine andere Materialstärke vermindert bzw. verhindert.at an advantageous embodiment of the Invention becomes a discontinuity in the load, such as force, in the transition of a material thickness on a different material thickness reduced or prevented.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieben. Es zeigenOne embodiment The invention is illustrated in the drawing and will be described below described in more detail. Show it
Die Kästen und Seitenteile bilden einen stabilen Rahmen, so daß durch die rundbogenartige Ausgestaltung die betriebsbedingten Thermospannungen entschärft werden, indem diese in Richtung auf die Rohrenden verschoben werden.The boxes and side panels form a stable frame, so that through the round arch-like design the operational thermoelectric voltages defused be moved by moving them towards the pipe ends.
