Abstract
Die Erfindung betrifft einen Kühler für ein Kraftfahrzeug mit einem Block, der aus mehreren parallelen Rohren besteht, wodurch ein Kühlmittel fließt, wobei Rohre mit mindestens zwei verschiedenen Tiefen vorgesehen sind. Zwei oder mehr beabstandete Rohre weisen eine Tiefe auf, die größer als die Tiefe der dazwischen liegenden Rohre ist und als Stützrohre ausgebildet sind. Hierbei werden Dauerfestigkeitsprobleme des Kühlers vermieden.The invention relates to a radiator for a motor vehicle with a block consisting of a plurality of parallel tubes, whereby a coolant flows, wherein pipes are provided with at least two different depths. Two or more spaced tubes have a depth greater than the depth of the intervening tubes and formed as support tubes. This fatigue problems of the cooler are avoided.
Description
Die Erfindung betrifft einen Kühler für ein Kraftfahrzeug mit den Merkmalen des Oberbegriffs des Anspruchs 1.The The invention relates to a cooler for a motor vehicle with the features of the preamble of claim 1.

der Druckschrift
Beide oben genannten Druckschriften beschreiben Kühler, die unterschiedliche Blocktiefen aufweisen, um diesen an die Bedingungen der Karosserie anzugleichen. Dennoch werden segmentweise nur einheitliche Blocktiefen eingesetzt.Both The above references describe coolers that are different Block depths to match the conditions of the body equalize. Nevertheless, segment-wise only uniform block depths used.
In Fahrzeugen mit unterschiedlicher Motorisierung ist es heute üblich, innerhalb einer Fahrzeugplattform die Kühlleistung durch Abwandlung der Kühler, genauer der Blocktiefe, an den jeweiligen Kühlbedarf anzupassen. Ausgangsbasis bildet dabei immer der größte Kühler, also die größte erforderliche Blocktiefe. An diesen Kühlern liegen dann lufteintrittsseitig wie -austrittsseitig die Anschlusselemente an, die dann meist für alle Varianten identisch sind (z. B. Kältemittelkondensator oder Lüfterzarge).In Vehicles with different motorization, it is common today, within a vehicle platform, the cooling capacity by modification of the radiator, more precisely the block depth, to adapt to the respective cooling requirements. base always forms the largest cooler, so the largest required Block depth. On these coolers Are then the air inlet side as-outlet side of the connection elements, then mostly for all variants are identical (eg refrigerant condenser or fan cowl).
Da die Kühlerhersteller in Rastern arbeiten, gibt es bestimmte Blocktiefenmaße und es kann vorkommen, dass in großen Rohrböden nur halb so tiefe Blöcke, wie für die Größe möglich wäre, gestellt werden. Hierbei gibt es teilweise erhebliche Dauerfestigkeitsprobleme, da die ungleiche Stützwirkung des Blocks bei Erwärmung zu Verzögen führt. Dabei ist es egal, ob die Rohre im Rohrboden mittig angeordnet oder einseitig verschoben angeordnet sind.There the cooler manufacturers Working in grids, there are certain block depths and it that can happen in large tube sheets only half as deep blocks, as for the size would be possible become. There are sometimes considerable fatigue problems, because the unequal support effect of the block when heated to retire leads. It does not matter whether the tubes are arranged centrally in the tubesheet or are arranged shifted one-sided.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, für einen Kühler eine verbesserte Ausführungsform anzugeben, die insbesondere mit einem großen Rohrboden und einer kleineren Blocktiefe so ausgebildet werden kann, dass die genannten Dauerfestigkeitsprobleme vermieden werden.Of the Present invention is based on the object for a cooler an improved embodiment Specify, in particular, with a large tube bottom and a smaller tube bottom Block depth can be formed so that the mentioned fatigue problems be avoided.
Erfindungsgemäß wird dieses Problem durch einen Kühler mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen des erfindungsgemäßen Kühlers ergeben sich aus den abhängigen Ansprüchen.According to the invention this Problem with a cooler solved with the features of claim 1. Advantageous developments of the cooler according to the invention from the dependent ones Claims.
Der erfindungsgemäße Kühler umfasst einen Block, der aus mehreren parallelen Rohren besteht, wodurch ein Kühlmittel fließt, wobei zwei oder mehr beabstandete Rohre eine Tiefe aufweisen, die größer als die Tiefe der dazwischen liegenden Rohre ist und als Stützrohre ausgebildet sind. Durch die Rohre mit größerer Tiefe ergibt sich eine Aussteifung der Rohrböden, was die Dauerfestigkeit des Kühlers verbessert.Of the Cooler according to the invention comprises a block consisting of several parallel tubes, thereby a coolant flows, wherein two or more spaced tubes have a depth greater than the depth of the intermediate tubes is and as support tubes are formed. Through the tubes with greater depth results in a Stiffening of the tubesheets, what the fatigue strength of the radiator improved.
In vorteilhafter Ausgestaltung der Erfindung weisen das erste und das letzte Rohr eine Tiefe auf, die größer als die Tiefe der dazwischen liegenden Rohre ist, und als Stützrohre ausgebildet sind. Diese Gestaltung liefert dem Kühler verbesserte Stabilität beim Einsatz weniger Rohre.In Advantageous embodiment of the invention, the first and the last pipe has a depth greater than the depth of the intervening lying tubes, and as support tubes are formed. This design provides the radiator with improved stability during use less pipes.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist der Kühler an den Enden und im mittleren Bereich des Kühlblocks mit Stützrohren versehen, die eine Tiefe aufzeigen, die größer als die Tiefe der restlichen Rohre ist. Diese Gestaltung wird benutzt, wenn eine höhere Stabilität erforderlich ist.In a further advantageous embodiment of the invention is the cooler at the ends and in the middle area of the cooling block with support tubes provide a depth greater than the depth of the rest Pipes is. This design is used when higher stability is required is.
Weitere Vorteile und Ausgestaltungen der Erfindung ergeben sich aus der nachfolgenden Beschreibung und den beiliegenden Zeichnungen.Further Advantages and embodiments of the invention will become apparent from the following description and the accompanying drawings.
Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It it is understood that the above and the following yet to be explained features not only in the specified combination, but also in other combinations or alone, without to leave the scope of the present invention.
Die Erfindung ist anhand mehrerer Ausführungsbeispiele in den Zeichnungen schematisch dargestellt und wird im Folgenden unter Bezugnahme auf die Zeichnungen ausführlich beschrieben.The Invention is based on several embodiments in the drawings schematically and will be described below with reference to the drawings in detail described.
