Description

Die Erfindung betrifft einen Wärmeübertrager gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a heat exchanger according to the preamble of claim 1.

Wärmeübertager, insbesondere Wärmeübertrager wie Gaskühler oder Kondensatoren, welche im Kraftfahrzeugbereich eingesetzt werden, sind im Wesentlichen aus Wellrippen-Flachrohr-Blöcken aufgebaut, die an jeweiligen gegenüberliegenden Endabschnitten in Sammelrohren enden. Üblicherweise werden im Stand der Technik Wärmeübertrager mittels eines Kassettierverfahrens hergestellt. Bei der Kassettierung von Wärrneübertragern, insbesondere bei der Kassettierung von Gaskühler, wird der Wellrippen-Flachrohr-Block gespannt und auf die Sammelrohre aufgepresst. Während des dann diesem Verfahrensschritt folgenden Transports des so vorgefertigten Wellrippen-Flachrohr-Blocks vom Blockfertiger bis zum Verlassen des Lötofens kann es jedoch durch Erschütterungen, Wärmedehnungen oder Eigenspannungen des Sammelrohres im Lötofen zu einer Relativbewegung des Sammelrohrs bezüglich der Flachrohre kommen. Dies hat zur Folge, dass die Flachrohre im Sammelrohr entweder zu tief oder zu wenig eingeschoben sind. Im Extremfall können die Sammelrohre sogar von den Flachrohren abrutschen, da das Sammelrohr lediglich über die Haftreibung der Flachrohre in in dem Sammelrohr vorgesehenen Durchzügen gehalten und positioniert wird.Heat exchangers, in particular heat exchangers such as gas coolers or condensers, which are used in the automotive sector, are essentially constructed of corrugated flat-tube blocks which terminate at respective opposite end portions in headers. Conventionally, in the prior art, heat exchangers are manufactured by means of a cassetting process. In the Kassettierung of Wärrneübertragern, especially in the cassettes of gas cooler, the corrugated finned flat tube block is stretched and pressed onto the manifolds. However, during the subsequent transport of the prefabricated corrugated flat-tube block from the block paver to the exit of the brazing furnace, vibrations, thermal expansions or residual stresses of the collecting tube in the brazing furnace can lead to a relative movement of the collecting tube relative to the flat tubes. This has the consequence that the flat tubes are inserted in the manifold too deep or too little. In extreme cases, the headers can even slip off the flat tubes, since the manifold only on the static friction of the flat tubes held and positioned in passages provided in the manifold.

Dies ist insbesondere beim Gaskühler problematisch, wo auf klassische Durchzüge verzichtet wird und lediglich eine Stanzung ausgeführt wird, welche ein größeres Maß verglichen mit einem Durchzug eines klassischen Kondensators aufweist.This is particularly problematic in the case of the gas cooler, where conventional passages are dispensed with and only one punching is performed, which has a greater degree compared to a passage of a classic capacitor.

Zum Befestigen der Wellenrippen-Flachrohr-Blöcke vor dem Verlöten sind daher im Stand der Technik verschiedene Verfahren bekannt.Therefore, various methods are known in the art for attaching the corrugated fin flat tube blocks prior to brazing.

Beispielsweise ist in DE 198 14 827 A1 ein Wärmeübertrager für ein Kraftfahrzeug beschrieben, welcher einen Wellrippen-Flachrohr-Block aufweist, der auf gegenüberliegenden Seiten durch zwei Seitenteile begrenzt wird, die ebenfalls als Flachrohrprofile gestaltet sind, welche zu den Flachrohrprofilen des Wellrippen-Flachrohr-Blocks identisch sind, jedoch nicht von einem Wärmeübertragungsmedium durchströmt werden. Der Wärmeübertrager ist in Ganzmetallbauweise ausgeführt, in dem sowohl der Wellrippen-Flachrohr-Block als auch an beiden Stirnseiten des Blocks vorgesehene Rohrböden jeweils aus Leichtmetall-Legierungen hergestellt sind. Jeder Rohrboden ist auf seinen gegenüberliegenden Seiten im Bereich seines vom Wellrippen-Flachrohr-Block weggerichteten Randes mit jeweils zwei zueinander beabstandeten, einstückig angeformten Biegelaschen versehen, die zur Sicherung der Flachrohrprofile am Wellrippen-Flachrohr-Block vor einer Verlötung nach außen umbiegbar sind. Dadurch übergreifen die als mechanisch wirkende Befestigungselemente dienenden Biegelaschen die Seitenteile außen formschlüssig, wodurch die Seitenteile am Wellrippen-Flachrohr-Block sowie an den Rohrböden positionsgesichert sind. Das zusätzliche Vorsehen eines Spannrahmens für einen Transport oder eine Lagerung des Wellrippen-Flachrohr-Blocks einschließlich der Seitenteile vor einer Verlötung kann somit vermieden werden.For example, in DE 198 14 827 A1 describes a heat exchanger for a motor vehicle, which has a corrugated flat-tube block which is bounded on opposite sides by two side parts, which are also designed as flat tube profiles which are identical to the flat tube profiles of the corrugated flat-tube block, but not of one Heat transfer medium to be flowed through. The heat exchanger is designed in all-metal construction, in which both the corrugated flat-tube block and provided on both end faces of the block tube plates are each made of light metal alloys. Each tubesheet is provided on its opposite sides in the region of its directed away from the corrugated flat-tube block edge with two spaced, integrally formed bending tabs which are umbiegbar to secure the flat tube profiles on corrugated flat-tube block before soldering to the outside. As a result, the bending tabs serving as mechanically acting fastening elements overlap the side parts in a form-fitting manner, as a result of which the side parts are position-secured on the corrugated ribbed flat-tube block and on the tubesheets. The additional provision of a clamping frame for transport or storage of the corrugated flat-tube block including the side parts before soldering can thus be avoided.

Jedoch ist die Herstellung der Biegelaschen aufwändig und erfordert zusätzliches Material,However, the production of the bending tabs is complex and requires additional material,

Daher ist es die Aufgabe der vorliegenden Erfindung, einen Wärmeübertrager vorzusehen, welcher ohne zusätzliche Teile eine sichere Fixierung des Wellrippen-Flachrohr-Blocks vor der Verlötung ermöglicht.Therefore, it is the object of the present invention to provide a heat exchanger, which enables secure fixing of the corrugated flat-tube block before soldering without additional parts.

Die Aufgabe der vorliegenden Erfindung wird durch einen Wärmeübertrager mit den Merkmalen gemäß Anspruch 1 gelöst. Vorteilhafte Weiterbildungen der vorliegenden Erfindung sind in den Untetansprüchen definiert.The object of the present invention is achieved by a heat exchanger with the features of claim 1. Advantageous developments of the present invention are defined in the Untetansprüchen.

Erfindungsgemäß wird ein Wärmeübertrager, insbesondere ein Gaskühler für ein Kraftfahrzeug, bereitgestellt, welcher einen Block aus Rohrelementen und Rippenelementen aufweist, wobei der Block an zumindest einer Seitenfläche mit einem Seitenteil versehen ist, und an zumindest einer Oberseite und/oder einer Unterseite auf ein Sammelrohr aufgepresst ist, welches jeweilig mit einer Vielzahl von Aussparungen zum Aufnehmen der Rohrelemente ausgebildet ist. Das zumindest an einer Seitenfläche des Blocks vorgesehene Seitenteil ist gemäß der Erfindung mit dem an zumindest einer von der Oberseite oder der Unterseite aufgepressten Sammelrohr verstemmt. Durch die erfindungsgemäße Konfiguration, d. h. durch Verstemmen des Blocks mit dem oder den Sammelrohr/Sammelrohren, ist es nicht erforderlich, zusätzliche Teile zum Fixieren während des Transports oder der Lagerung des Blocks vor einem Verlöten vorzusehen Es wird auf einfache und kostengünstige Weise eine effektive Fixierung des Blocks und des Sammelrohrs bzw. der beidseitigen Sammelrohre erzielt. Darüber hinaus wird durch das Verstemmen eine gleichmäßige Einschubtiefe der Rohrelemente in das Sammelrohr sichergestellt, wobei Druckverluste im Wärmeübertrager reduziert werden. Außerdem wird die Prozesssicherheit erhöht sowie eine Kostenreduzierung durch Optimierung und Verkleinerung des Sammelrohrquerschnitts erzielt, und es kommt zu geringen Toleranzschwankungen der äußeren Abmessungen des Wärmeübeitragers.According to the invention, a heat exchanger, in particular a gas cooler for a motor vehicle, is provided, which has a block of tubular elements and rib elements, wherein the block is provided on at least one side surface with a side part, and pressed on at least one top and / or one bottom on a manifold is, which is respectively formed with a plurality of recesses for receiving the tubular elements. The provided at least on one side surface of the block side part is caulked according to the invention with the at least one of the top or the bottom pressed-together manifold. Due to the configuration according to the invention, ie by caulking the block with the collection tube (s), it is not necessary to provide additional parts for fixing during transport or storage of the block prior to soldering Blocks and the manifold or the two-sided headers achieved. In addition, a uniform insertion depth of the pipe elements is ensured in the manifold by caulking, with pressure losses are reduced in the heat exchanger. In addition, the process reliability is increased and a cost reduction through optimization and reduction of the manifold cross-section achieved, and there is little tolerance variations in the external dimensions of the Wärmubeitragers.

Die gegenüberliegenden schmalen Seiten des Blocks 2 sind jeweils mit einem Seitenteil 8, 8' versehen, welches jeweils an einem oberen Endabschnitt und einem unteren Endabschnitt (nicht dargestellt) in einer äußeren als Durchzug ausgebildeten Aussparung 10' der Vielzahl von als Durchzüge ausgebildete Aussparungen 10 des Sammelrohrs 5 aufgenommen bzw. gepresst ist Vor dem Verlöten der Teile des Wärmeübeliragers 1 werden die einzelnen Rohrelemente 3 in der hier dargestellten Ausführungsform des Standes der Technik lediglich durch die Haftreibung der Rohrelemente 3 und der Seitenteile 8, 8' in den als Durchzüge ausgebildeten Aussparungen 10, 10' des Sammelrohrs 5 gehalten, was beim Transport zum Lötöfen zu Problemen führen kann, wenn sich die Position der Rohrelemente 3 bezüglich des Sammelrohrs 5 ändert oder sie sogar vollständig aus dem Sammelrohr 5 herausrutschen.The opposite narrow sides of the block 2 are each provided with a side part 8, 8 ', each at an upper end portion and a lower end portion (not shown) in an outer formed as a passage recess 10' of the plurality of as passages formed before soldering the parts of the heat roller bearing 1, the individual tube elements 3 in the embodiment of the prior art shown here only by the static friction of the tubular elements 3 and the side parts 8, 8 'in as Passages formed recesses 10, 10 'of the manifold 5, which can lead to problems during transport to the soldering furnaces, when the position of the tubular elements 3 changes with respect to the manifold 5 or even completely slip out of the manifold 5.

Fig. 2 zeigt eine perspektivische Ansicht eines oberen bzw. rechten Abschnitts eines Wärmeübertragers 1 gemäß dem Stand der Technik, welcher hier ohne Rippenelemente 4 und lediglich mit Rohrelementen 3 dargestellt ist. Wie in dem Ausschnitt erkannt werden kann, weist das Sammelrohr 5 eine Vielzahl von als Durchzüge ausgebildeten Aussparungen 10 und beidseitig jeweils eine als äußerer Durchzug ausgebildete Aussparung 10' auf, von denen hier nur eine dargestellt ist. Alle als Durchzüge ausgebildeten Aussparungen 10, 10' sind gleich ausgebildet und in einem gleichmäßigen Abstand voneinander an dem Sammelrohr 5 angeordnet. In den äußeren Durchzug 10' ist das Seitenteil 8 auf die gleiche Art und Weise wie die Rohrelement 3 eingeführt bzw, eingepresst, wobei als Seitenteil 8 hier ein entsprechend geformter Blechstreifen ist. Das Sammelrohr 5 wird vor dem Verlöten - wie bereits oben beschrieben - dabei lediglich durch die Haftreibung der einzelnen Rohrelemente 3 bzw. der Seitenteile 8, 8' auf diesen gehalten und kann sich daher leicht lösen oder verrutschen. Fig. 2 shows a perspective view of an upper or right portion of a heat exchanger 1 according to the prior art, which is shown here without rib elements 4 and only with tubular elements 3. As can be seen in the section, the collecting tube 5 has a plurality of passages 10 formed as passages and on both sides each formed as an outer passage recess 10 ', of which only one is shown here. All formed as passages recesses 10, 10 'are of identical design and arranged at a uniform distance from each other on the manifold 5. In the outer passage 10 ', the side part 8 is inserted in the same manner as the pipe element 3 or, pressed, with as side part 8 here is a correspondingly shaped sheet metal strip. The collecting tube 5 is - as already described above - before soldering - only held by the static friction of the individual tube elements 3 and the side parts 8, 8 'on this and can therefore easily solve or slip.

Fig. 3 ist eine weitere perspektivische Ansicht eines Abschnitts eines Wärmeübertragers 1 gemäß dem Stand der Technik mit einem Block 2 aus abwechselnd angeordneten Rohrelementen 3 und Rippenelementen 4, wobei die Rohrelemente 3 an ihren Endabschnitten (nicht dargestellt) in das Sammelrohr 5 durch jeweilige als Durchzüge ausgebildete Aussparungen 10 eingeführt sind. Als Seitenteils 8 ist in dieser Ausführungsform ein nicht von einem Warme- oder Kühlmittel durchströmtes Rohrelement verwendet worden ist, welches mit seinem Endabschnitt 9 in eine als äußerer Durchzug ausgebildeten Aussparung 10' von der Vielzahl von als Durchzüge ausgebildeten Aussparungen 10 des Sammelrohrs 5 eingesetzt ist. Im Gegensatz zu der in Fig. 2 dargestellten Ausführungsform ist die äußere als Durchzug ausgebildete Aussparung 10' offen ausgeführt, und unterscheidet sich hierdurch von den als Durchzüge ausgebildeten Aussparungen 10 des Sammelrohrs 5. Fig. 3 is another perspective view of a portion of a heat exchanger 1 according to the prior art with a block 2 of alternately arranged tubular elements 3 and fin elements 4, wherein the tube elements 3 at their end portions (not shown) in the manifold 5 by respective recesses formed as passages 10th introduced are. As a side part 8 in this embodiment, a non-flowed through by a heat or coolant tube element has been used, which is used with its end portion 9 in a formed as an outer passage recess 10 'of the plurality of passages formed as passages 10 of the manifold 5. Unlike the in Fig. 2 illustrated embodiment, the outer recess formed as a passage 10 'is made open, and thus differs from the formed as passages recesses 10 of the manifold fifth

Fig. 4 ist eine perspektivische Ansicht eines Abschnitts eines Wärmeübertragers 1 gemäß einer Ausführungsform. Der hier nur ausschnittsweise dargestellte Block 2 weist wiederum abwechselnd angeordnete Rohrelemente 3 und Rippenelemente 4 auf, welche als Flachrohre und Wellrippen ausgebildet sind. Wie in der in Fig. 3 dargestellten Ausführungsform ist auch in dieser Ausführungsform das Seitenteil 8 als ein nicht von einem Wärme- oder Kühlmedium durchströmtes Rohrelement 3 ausgebildet und bildet einen seitlichen Abschluss des Blocks 2. Alternativ kann anstelle eines nicht von einem Wärme- oder Kühlmittel durchströmten Rohrelements 3 jedoch auch ein entsprechend geformter Blechstreifen oder ein Profilelement verwendet werden. Der Block 2 ist an seiner Oberseite 13 und/oder Unterseite (nicht dargestellt) auf das Sammelrohr 5 aufgepresst, indem die Rohrelemente 3 an ihren Endabschnitten (nicht dargestellt) in jeweilige Durchzüge 10, welche in dem Sammelrohr 5 vorgesehen sind, gepresst sind. In eine als äußerer Durchzug ausgebildete Aussparung 10' des Sammelrohrs 5 ist ein Endabschnitt 9 des Seitenteils 8 gepresst, wobei der Endabschnitt 9 über eine bestimmte Länge in das Sammelrohr 5 hineinragt Zur Fixierung des Seitenteils 8 in dieser Position weist das Seitenteil 8 an diesem Endabschnitt 9 zwei punktuelle Verformungen 11, 11' auf. Der gegenüberliegende Endabschnitt des Seitenteils 8, weicher hier nicht dargestellt ist, ist im Wesentlichen ebenso aufgebaut bzw. ausgebildet. Die zwei punktuelle Verformungen 11, 11', welche im Inneren des Sammelrohres 5 auf gegenüberliegenden Seiten an den Randabschnitten 12, 12' des Seitenteils 8' vorgesehen sind, verhindern dass das Sammelrohr 5 von dem Seitenteil 8, 8' abrutscht. Die zwei punktuellen Verformungen 11, 11' sind in dieser Ausführungsform im Wesentlichen rund ausgebildet, können aber jedoch auch in jeglicher anderer Form ausgebildet sein, wie beispielsweise vier-, sechs- oder achteckig. Zwei weitere punktuelle Verformungen 11', 11'", welche hier viereckig ausgebildet sind, sind auf gegenüberliegenden Seiten an den Randabschnitten 12, 12' vor dem äußeren Durchzug 10', durch welchen das Seitenteil 8 geschoben ist - d. h. außerhalb des Sammelrohrs 5 - an einem äußeren Abschnitt 14 des Seitenteils 8 vorgesehen, so dass das Seitenteil 8 nicht zu tief in das Sammelrohr 5 eingeschoben wird. Somit ist das Seitenteil 8 mit dem Sammelrohr 5 durch die punktuellen Verformungen 11, 11', 11", 11'" verstemmt und kann auch vor dem Verlöten nicht in seiner Position verschoben werden oder aus dem Sammelrohr 5 herausrutschen. Die äußeren Durchzüge 10' können alternativ auch als offene oder geschlossene Durchzüge bzw. Aussparungen 10', wie in Zusammenhang mit Figur 3 beschrieben wurde, ausgeführt sein bzw. eine andere Toleranzlage besitzen. Fig. 4 is a perspective view of a portion of a heat exchanger 1 according to an embodiment. The block 2, which is only partially shown here, again has alternately arranged tube elements 3 and rib elements 4, which are designed as flat tubes and corrugated ribs. As in the Fig. 3 embodiment shown, the side part 8 is formed as a non-flowed through by a heat or cooling medium tube member 3 and forms a lateral termination of the block 2. Alternatively, instead of a non-flowed through by a heat or coolant tube member 3 but also a corresponding shaped sheet metal strip or a profile element can be used. The block 2 is (not shown) on its upper side 13 and / or pressed onto the manifold 5 by the tube elements 3 (not shown) at their end portions in respective passages 10 which are provided in the manifold 5, are pressed. In an opening formed as an outer passage 10 'of the collecting tube 5, an end portion 9 of the side part 8 is pressed, wherein the end portion 9 protrudes over a certain length in the manifold 5 For fixing the side part 8 in this position, the side part 8 at this end portion. 9 two punctual deformations 11, 11 '. The opposite end portion of the side part 8, which is not shown here, is constructed or formed substantially the same. The two punctual deformations 11, 11 ', which in the interior of the manifold 5 on opposite sides the edge portions 12, 12 'of the side part 8' are provided, prevent the collecting tube 5 from slipping off the side part 8, 8 '. The two punctiform deformations 11, 11 'are substantially round in this embodiment, but may be formed in any other shape, such as four-, six- or octagonal. Two further punctual deformations 11 ', 11'", which are here quadrangular, are on opposite sides of the edge portions 12, 12 'before the outer passage 10', through which the side part 8 is pushed - ie outside of the manifold 5 - to an outer portion 14 of the side part 8 is provided, so that the side part 8 is not inserted too deeply into the collecting tube 5. Thus, the side part 8 with the manifold 5 by the punctual deformations 11, 11 ', 11 ", 11'" caulked and can not be displaced in position before soldering or slip out of the manifold 5. The outer passages 10 'may alternatively as open or closed passages or recesses 10', as in connection with FIG. 3 has been described, executed or have a different tolerance position.

Insgesamt betrachtet kann mit dem so ausgestalteten Wärmeübertrager 1 auf einfache und kostengünstige Art und Weise eine sichere Fixierung des Sammelrohrs 5 an dem Seitenteil 8, 8' des Blocks 2 erzielt werden, so dass das Sammelrohr 5 auch vor dem Verlöten nicht von den Seitenteilen 8, 8' abrutschen kann oder sich die Position des Sammelrohrs 5 bezüglich der Seitenteile 8, 8' ändern kann.Overall, can be achieved with the thus designed heat exchanger 1 in a simple and cost-effective manner, a secure fixation of the manifold 5 on the side part 8, 8 'of the block 2, so that the manifold 5 not even before soldering from the side parts 8, 8 'can slip or the position of the manifold 5 with respect to the side parts 8, 8' can change.
