Abstract
Description
Die Erfindung betrifft einen Wärmeübertrager gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a heat exchanger according to the preamble of
Wärmeübertrager werden beispielsweise als Kondensatoren in einem Kühlmittelkreislauf von Kraftfahrzeugklimaanlagen eingesetzt, um gasförmiges, überhitztes Kältemittel auf eine Verflüssigungstemperatur bzw. darunter abzukühlen und zu verflüssigen. Die dem Kältemittel entzogene Wärme wird dabei an die Umgebung abgegeben. Innerhalb des Kondensators wird das Kältemittel durch eine Vielzahl von Rohrelementen geleitet, welche an ihren jeweiligen gegenüberliegenden Enden in Sammelrohre enden bzw. münden, von welchen eines vorzugsweise mit einem Sammelbehälter fluidverbunden sind.Heat exchangers are used, for example, as condensers in a coolant circuit of motor vehicle air conditioning systems to cool and liquefy gaseous, superheated refrigerant to a liquefaction temperature or below. The heat extracted from the refrigerant is released to the environment. Within the condenser, the refrigerant is directed through a plurality of tubular members which terminate at their respective opposite ends in header pipes, one of which is preferably fluidly connected to a header tank.
Die Schnittstellen des Kondensators, z. B. zwischen Sammelrohr und Sammelbehälter, werden üblicherweise mittels Lötverfahren miteinander verbunden, um eine ausreichende und dauerhafte Dichtigkeit zwischen den einzelnen Bauteilen vorzusehen. Wenn die Sammelrohre und/oder Sammelbehälter aus geschweißten Rohren hergestellt sein, kann deren Oberfläche bereits mit einer lötfähigen Beschichtung versehen sein, so dass zum Verbinden dieser Komponenten mittels eines Lötverfahrens (z. B. im Lötofen) lediglich ein zusätzliches Flussmittel notwendig ist. Jedoch werden im Stand der Technik auch extrudierte Sammelrohre und Sammelbehälter verwendet.The interfaces of the capacitor, z. B. between manifold and sump, are usually connected to each other by means of soldering to provide a sufficient and lasting tightness between the individual components. If the headers and / or sumps are made of welded tubes, their surface may already be provided with a solderable coating so that they can be joined together These components by means of a soldering process (eg in the soldering oven) only an additional flux is necessary. However, extruded headers and sumps are also used in the art.
Beispielsweise ist in
Um einen Sammelbehälter auszubilden, werden im Stand der Technik Profilelemente verwendet, welche die Strömungsöffnungen aufweisen und welche mit dem Sammelbehälterrohr verbunden sind. Auch diese Profilelemente können als Extrusionsteil hergestellt werden.In order to form a collecting container, profile elements are used in the prior art, which have the flow openings and which are connected to the sump tube. These profile elements can be manufactured as an extrusion.
In
Wenn sowohl das Sammelbehälterrohr als auch das Profilelement als extrudierte Bauteile hergestellt sind, besteht hinsichtlich des Vorsehens einer dichten Lötverbindung zwischen den beiden Bauteilen ein Problem darin, dass sowohl ein lötfähiges Material auf den beiden zu verbindenden Oberflächen der Bauteile als auch ein Flussmittel zum Löten erforderlich sind.When both the sump tube and the profiled element are fabricated as extruded components, there is a problem in providing a solder joint between the two components that both a solderable material on the two surfaces of the components to be joined and a flux for soldering are required ,
Um eine möglichst dichte Lötverbindung herzustellen, kann in diesem Fall beispielsweise ein Lötring verwendet werden, der entweder auf dem äußeren Umfang des Profilelements und des daran angrenzenden Sammelbehälterrohrs angeordnet wird oder der im Inneren des Profilelements angeordnet wird. Bei der ersten Alternative ist jedoch nachteilig, dass hierzu eine Fixierung des Rings auf dem äußeren Umfang des Sammelbehälterrohrs während des Lötens im Lötofen notwendig wäre und möglicherweise das Lot nicht in den zu füllenden Spalt zwischen dem Profilelement und dem Sammelbehälterrohr fließt. Die zweite Alternative ist in Bezug auf einen hierzu erforderlichen zusätzlichen Bearbeitungsschritt des Profilelements nachteilig und es besteht hierbei darüber hinaus die Gefahr, dass das Lot zu der Dichtoberfläche des Profilelements abfließt.In order to produce a dense solder joint as possible, in this case, for example, a solder ring can be used, which is either on the outer periphery of the profile element and the collecting container tube adjacent thereto is arranged or which is arranged in the interior of the profile element. In the first alternative, however, is disadvantageous that for this purpose a fixation of the ring on the outer circumference of the sump tube during soldering in the soldering oven would be necessary and possibly the solder does not flow into the gap to be filled between the profile element and the sump tube. The second alternative is disadvantageous in relation to an additional processing step of the profile element required for this purpose, and there is moreover the risk that the solder will flow off to the sealing surface of the profile element.
Daher ist es die Aufgabe der vorliegenden Erfindung, eine dichte und auf einfache Art und Weise herstellbare Verbindung zwischen einem Profilelement und einem Sammelbehälterrohr eines Wärmeübertragers, welche beide als extrudierte Teile hergestellt sind, vorzusehen.Therefore, it is the object of the present invention to provide a tight and easily manufacturable connection between a profile element and a header tube of a heat exchanger, which are both manufactured as extruded parts.

Durch Einfügen des zylindrischen Elements direkt in das Profilelement werden zusätzliche Bearbeitungsschritte vermieden. Auch ist eine zusätzliche Fixierung des zylindrischen Elements während des Lötens im Lötofen nicht erforderlich.According to the invention, a heat exchanger, in particular a condenser for a motor vehicle, is provided which has a block which has a multiplicity of tubular elements which respectively open at at least one pipe end or at both pipe ends into a collecting pipe which is in fluid communication with a collecting container and which Container consists of at least one profile element and an extruded collection container tube, wherein the compound of the profile element and the collection container tube is a solder joint, which takes place via a cylindrical element arranged in the profile element. By inserting the cylindrical element directly into the profile element additional processing steps are avoided.

Gemäß einer bevorzugten Ausführungsform ist das zylindrische Element in einem Endabschnitt des Profilelements angeordnet.According to a preferred embodiment, the cylindrical element is arranged in an end portion of the profile element.
Gemäß noch einer bevorzugten Ausführungsform ist das zylindrische Element mit einem ersten Abschnitt in dem Endabschnitt des Profilelements angeordnet, und steht mit einem zweiten Abschnitt über den Endabschnitt des Profilelements hervor.

Gemäß noch einer weiteren bevorzugten Ausführungsform weist der Endabschnitt des Profilelements eine Innenwand auf, welche sich von einem äußeren Ende des Profilelements nach innen konisch verjüngt. Durch diese Ausgestaltung des ersten Endabschnitts wird eine gute Benetzung und somit eine zuverlässige Lötverbindung zwischen den beiden Bauteilen erreicht.According to yet another preferred embodiment, the end portion of the profile element has an inner wall which tapers inwardly conically from an outer end of the profile element. This embodiment of the first end section achieves good wetting and thus reliable soldering connection between the two components.

Durch den verkleinerten Innendurchmesser des ersten gestuften Abschnitts gegenüber dem sich nach innen verjüngenden Abschnitt kann das in den Endabschnitt des Profilelements einzufügende Sammelbehälterrohr in diesem mittels Presssitz gehalten bzw. fixiert werden.Still preferably, the tapered inward portion of the end portion terminates at a first stepped portion in which the end portion of the profile member is formed as a hollow cylinder, wherein the inner diameter of the first stepped portion is smaller than the smallest inner diameter of the conically inwardly tapering portion. Due to the reduced inner diameter of the first stepped portion relative to the inwardly tapered portion of the inserted into the end portion of the profile element collecting container tube can be held or fixed therein by means of press fit.
In noch einer weiteren bevorzugten Ausführungsform endet der erste gestufte Abschnitt an einem zweiten gestuften Abschnitt, in welchem der Endabschnitt des Profilelements hohlzylindrisch ausgebildet ist, wobei der Innendurchmesser des zweiten gestuften Abschnitts kleiner ist als der Innendurchmesser des ersten gestuften Abschnitts.In yet another preferred embodiment, the first stepped portion terminates at a second stepped portion in which the end portion of the profile member is formed as a hollow cylinder, wherein the inner diameter of the second stepped portion is smaller than the inner diameter of the first stepped portion.
Besonders bevorzugt ist es, wenn das zylindrische Element in dem sich verjüngenden Abschnitt des Endabschnitts des Profilelements angeordnet ist.It is particularly preferable if the cylindrical element is arranged in the tapering section of the end section of the profile element.
Vorzugsweise liegt das zylindrische Element an einer ersten Stufe des ersten gestuften Abschnitts an. Die erste Stufe bildet somit vorteilhafterweise einen Anschlag bzw. eine Anlagefläche für das zylindrische Element.Preferably, the cylindrical member abuts a first step of the first stepped portion. The first stage thus advantageously forms a stop or a contact surface for the cylindrical element.
Gemäß noch einer bevorzugten Ausführungsform ist das zylindrische Element als Ring ausgebildet, welcher einen Grundkörper aufweist, der mit einer Beschichtung aus einem lötfähigen Material versehen ist.According to yet a preferred embodiment, the cylindrical element is formed as a ring, which has a base body which is provided with a coating of a solderable material.

Besonders bevorzugt ist der Endabschnitt des rohrförmigen Elements in ersten gestuften Abschnitt des Profilelements eingepresst.Particularly preferably, the end portion of the tubular element is pressed into the first stepped portion of the profile element.
Vorzugsweise liegt der Endabschnitt des rohrförmigen Elements an einer zweiten Stufe des zweiten gestuften Abschnitts des Profilelements an. Somit bildet die zweite Stufe auf vorteilhafte Weise einen Anschlag bzw. eine Anlagefläche für den in das Profilelement eingeführten Endabschnitt des rohrförmigen Elements.Preferably, the end portion of the tubular member abuts a second step of the second stepped portion of the profile member. Thus, the second stage advantageously forms a stop or abutment surface for the end portion of the tubular element inserted in the profiled element.
Gemäß einer weiteren bevorzugten Ausführungsform liegt der zweite Abschnitt des zylindrischen Elements an zumindest einem Abschnitt an dem äußeren Umfang des rohrförmigen Elements an. Dies sieht eine besonders zuverlässige Abdichtung der beiden Bauteile bzw. der Verbindung der beiden Bauteile vor.According to another preferred embodiment, the second portion of the cylindrical member abuts at least a portion on the outer periphery of the tubular member. This provides for a particularly reliable sealing of the two components or the connection of the two components.
