Abstract
Description
Die Erfindung betrifft einen Wärmetauscher für Kraftfahrzeuge mit einem Rippen – Flachrohr – Block, bestehend aus wenigstens zwei Reihen aus Flachrohren mit dazwischen angeordneten Rippen, durch die Kühlluft hindurchströmt, wobei die Enden der Flachrohre eine Querschnittserweiterung aufweisen und mit ihren Breitseiten aneinander anliegen, um die eine Reihe zu bilden, sowie mit den Schmalseiten der einen Reihe zu den Schmalseiten der nächsten Reihe weisen, um den Rippen – Flachrohr – Block zu bilden, wobei die Enden in gegenüberliegende Sammel – oder Umlenkkästen münden, und wobei die Enden der Flachrohre mit Verbindungsrändern der Sammel – oder Umlenkkästen in Kontakt und mittels Löten verbunden sind.The The invention relates to a heat exchanger for motor vehicles with a ribbed flat tube block, consisting of at least two rows of flat tubes with in between arranged ribs, through the cooling air flowing, wherein the ends of the flat tubes have a cross-sectional widening and abut each other with their broadsides, around the one row to form, as well as with the narrow sides of the one row to the narrow sides the next Row point to the ribbed flat tube block form, wherein the ends open into opposite collection or deflection boxes, and wherein the ends of the flat tubes with connecting edges of the collecting or deflecting boxes in Contact and by soldering are connected.
Ein
Wärmetauscher
der beschriebenen Art ist aus der
Es gibt jedoch fertigungstechnische Probleme, da die Flachrohre der Flachrohrreihen mit ihren Schmalseiten unmittelbar aneinander anliegen und miteinander verlötet werden müssen. Wenn die Flachrohrenden nicht auf das Sorgfältigste für diese Verbindung vorbereitet sind, kann es zu Verschiebungen der Flachrohre in den Rohrreihen und zu Undichtigkeiten in den Lötverbindungen kommen.It However, there are manufacturing problems, since the flat tubes of the Flat tube rows with their narrow sides directly abut each other and soldered together Need to become. If the flat tube ends are not prepared in the most careful way for this connection There may be shifts of the flat tubes in the rows of tubes and leaks in the solder joints come.
Die Aufgabe der vorliegenden Erfindung besteht darin, den Wärmetauscher aus dem Oberbegriff so weiterzubilden, dass die Montage vereinfacht und undichte Lötverbindungen weitgehend vermieden werden.The Object of the present invention is the heat exchanger from the preamble so educate that simplifies the installation and leaking solder joints be largely avoided.
Die Lösung dieser Aufgabe wird bei dem Wärmetauscher mit den Merkmalen des Oberbegriffs des Anspruchs 1 erfindungsgemäß durch dessen Kennzeichen vollständig erreicht. Die Ansprüche 2 bis 8 betreffen vorteilhafte Weiterbildungen und Ausgestaltungen.The solution This object is achieved in the heat exchanger with the features of the preamble of claim 1 according to the invention by its plate completely reached. The requirements 2 to 8 relate to advantageous developments and refinements.
Weil an den Enden zwischen den Schmalseiten der Flachrohre der wenigstens zwei Flachrohrreihen ein im Wesentlichen flacher Blechstreifen eingefügt ist, der lotplattiert ist und der in Längsrichtung der Flachrohre einen aus der Ebene des Blechstreifens vorspringenden Anschlag bietet bzw. zur Verfügung stellt, kann die Montage des Rippen – Flachrohr – Blocks vereinfacht werden, weil die Flachrohre des Blocks auf einem einheitlichen Niveau zu liegen kommen. Das Verschieben der Flachrohre in Rohrlängsrichtung wird also vermieden. Ferner kann mit höherwertigen Lötverbindungen gerechnet werden, weil der Blechstreifen an den Flachrohrenden zusätzliches Lotmaterial zur Verfügung stellt.Because at the ends between the narrow sides of the flat tubes of at least two flat tube rows a substantially flat sheet metal strip is inserted, the solder is soldered and the longitudinal direction of the flat tubes offers a projecting from the plane of the metal strip stop or provides, Can be the assembly of the rib - flat tube block be simplified because the flat tubes of the block on a uniform Level to come to rest. Moving the flat tubes in the tube longitudinal direction is thus avoided. Furthermore, with higher quality solder joints can be expected, because the metal strip on the flat tube ends additional Lot material available provides.
Es ist vorgesehen, dass über die Länge der Flachrohre zwischen den Schmalseiten benachbarter Flachrohrreihen ein Abstand vorhanden ist, der der Dicke des Blechstreifens entspricht, so dass die Verbindung, insbesondere die Verlötung, der wenigstens zwei Flachrohrreihen nur im Bereich des Blechstreifens vorgenommen wird. Die Rippen des Blocks für die Kühlluft reichen trotz des erwähnten Abstandes über wenigstens zwei Flachrohrreihen hinweg.It is provided that over the length the flat tubes between the narrow sides of adjacent rows of flat tubes there is a distance equal to the thickness of the sheet metal strip, so that the connection, in particular the soldering, the at least two rows of flat tubes only in the area of the metal strip is made. The ribs of the Blocks for the cooling air last despite the mentioned Distance over at least two rows of flat tubes.
Es ist vorteilhaft, wenn der aus der Ebene des Blechstreifens vorspringende bzw. herausragende Anschlag für die Flachrohre dadurch geschaffen wird, dass der Blechstreifen in Abständen angeordnete und in entgegengesetzte Richtung weisende Ausformungen aufweist, die auf einer Geraden liegen.It is advantageous if the protruding from the plane of the metal strip or outstanding stop for the flat tubes is created by the sheet metal strip in intervals arranged and pointing in opposite directions formations which lie on a straight line.
Gleichartige Wirkungen werden dadurch erreicht, dass der Blechstreifen in Abständen angeordnete Laschen aufweist, die auf einer Geraden liegen und in entgegengesetzte Richtung weisen.similar Effects are achieved by arranging the metal strip at intervals Has tabs that lie on a straight line and in opposite directions Direction.
Wegen des Lotdepots ist es vorteilhaft, wenn der Blechstreifen vorzugsweise beidseitig lotplattiert ist.Because of the solder deposit, it is advantageous if the metal strip preferably Lotplattiert on both sides.
Es ist weiter vorgesehen, dass der eine Längsrand des Blechstreifens über dem Niveau der Flachrohrenden liegt.It is further provided that the one longitudinal edge of the metal strip over the Level of the flat tube ends is.
Die vorgeschlagene Ausbildung ist vorzugsweise bei solchen Wärmetauschern vorgesehen, bei denen die Querschnittserweiterung der Flachrohrenden mittels Trennschnitts in den Schmalseiten und Abbiegens der Breitseiten der Flachrohrenden ausgeführt wird.The Proposed training is preferably in such heat exchangers provided in which the cross-sectional widening of the flat tube ends by separating cut in the narrow sides and bending the broadsides the flat tube ends executed becomes.
Es ist ferner von Vorteil, wenn der Blechstreifen so verformt wird, dass er gleichzeitig die Flachrohrenden beider Rohrreihen zusammenhält. Er weist dazu beispielsweise Klammern auf, die jeweils zwei Schmalseiten zweier Flachrohre zusammenhalten.It is also advantageous if the sheet metal strip is deformed, that he holds together the flat tube ends of both rows of tubes at the same time. He points For example, on brackets, each with two narrow sides hold together two flat tubes.
