Description

Die Erfindung betrifft einen Wärmeübertrager für ein Kraftfahrzeug mit einem zwischen zwei Sammelkästen angeordneten Rippen/Rohrblock, wobei alle Rohrenden des Rippen/Rohrblockes im Bereich jedes Sammelkastens aufgeweitet und flächig aneinander anschließend zu einem Rohrendenpaket zusammengefügt sind, und wobei die beiden Sammelkästen jeweils bündig abschließend auf das zugeordnete Rohrendenpaket aufgesetzt und dicht mit diesem verlötet sind.The invention relates to a heat exchanger for a motor vehicle with one arranged between two collecting boxes Ribs / tube block, with all tube ends of the ribs / tube block in the area of each collection box expanded and flat against each other then assembled into a tube end package are, and the two collection boxes each flush placed on the assigned tube end package and are tightly soldered to it

Ein solcher Wärmeübertrager ist in der nicht vorveröffentlichten DE 195 43 986.4 beschrieben. Bei diesem Wärmeübertrager ist ein aus Flachrohren und Wellrippen zusammengesetzter Rippen/Rohrblock vorgesehen, wobei die Rohrenden der Flachrohre derart mit rechteckigem Querschnitt aufgeweitet sind, daß die benachbarten Rohrenden mit ihren die Breitseiten darstellenden Wandungsabschnitten flächig in einer Reihe aneinanderliegen. Die die Schmalseiten der aufgeweiteten Rohrenden darstellenden Wandungsabschnitte sind auf jeder Seite in einer gemeinsamen Flucht ausgerichtet, so daß die Rohrenden auf den gegenüberliegenden Seiten der Flachrohre jeweils ein kompaktes und dicht aneinanderliegendes Rohrendenpaket bilden. Auf jedes Rohrendenpaket ist jeweils ein Sammelkasten aufgesetzt, der mit seinen Seitenwandungen die durch die Schmalseiten der Rohrenden gebildete Flucht außen übergreift und bündig an dieser durch die Schmalseiten gebildeten Flucht anliegt. Da die Sammelkästen direkt die aufgeweiteten Rohrenden übergreifen und diese durch das flächige Aneinanderliegen in Längsrichtung jedes Sammelkastens bereits eine dichte Verbindung schaffen, benötigt der Wärmeübertrager im Bereich der Sammelkästen keinen zusätzlichen Boden. Sowohl die Sammelkästen als auch der Rippen/Rohrblock sind aus Metallblech hergestellt und in einem gemeinsamen Lötvorgang miteinander verbindbar.Such a heat exchanger is in the unpublished DE 195 43 986.4. With this heat exchanger is a composite of flat tubes and corrugated fins Ribs / tube block provided, the tube ends of the flat tubes are expanded with a rectangular cross-section, that the adjacent pipe ends with their broad sides Wall sections lie flat in a row. The narrow sides of the widened pipe ends Representing wall sections are in one on each side aligned escape so that the pipe ends on the opposite sides of the flat tubes each a compact and form a closely spaced tube end package. A collecting box is placed on each tube end package, the one with the side walls that through the narrow sides the pipe ends formed overlap outside and lies flush against this escape formed by the narrow sides. Since the collection boxes directly the expanded pipe ends overlap and these by the flat abutting in Already a tight connection in the longitudinal direction of each collecting box create, the heat exchanger needs in the area of Collection boxes no additional floor. Both the collection boxes as well as the fins / tube block are made of sheet metal and can be connected to one another in a common soldering process.

Aufgabe der Erfindung ist es, einen Wärmeübertrager der eingangs genannten Art zu schaffen, der eine verbesserte Führung des durch die Sammelkästen und die Flachrohre des Rippen/Rohrblockes geleiteten Strömungsmediums ermöglicht.The object of the invention is to provide a heat exchanger at the beginning to create a better leadership through the collecting boxes and the flat tubes of the fins / tube block conducted flow medium allows.

Diese Aufgabe wird dadurch gelöst, daß in wenigstens einem Sammelkasten wenigstens eine den Sammelkasten unterteilende Trennwand vorgesehen ist, die in ihrer Außenkontur derart auf eine Innenkontur einer Wandung des Sammelkastens abgestimmt ist, daß sie umlaufend dicht mit der Innenkontur verlötbar ist, und die einen Haltefuß zum Aufstecken der Trennwand auf zwei flächig aneinanderschließende Wandungsabschnitte benachbarter Rohrenden des Rohrendenpaketes aufweist. Durch das Vorsehen wenigstens einer Trennwand in einem der beiden Sammelkästen ist es möglich, das Strömungsmedium innerhalb des Rippen/Rohrblockes U-förmig umzuleiten, wodurch die Anschlüsse für die Zu- und die Ableitung des Strömungsmediums an lediglich einem der Wasserkästen vorgesehen sein kann. Die Sammelkästen weisen je nach ihrem Anschluß an den entsprechenden Strömungsmediumkreislauf Sammler- oder Verteilerfunktion auf. Als Strömungsmedium kann insbesondere Kühlflüssigkeit, Wasser oder Luft vorgesehen sein, wobei der Wärmeübertrager insbesondere als Kühlflüssigkeit/Luft- Wasser/Luft- oder Luft/Luft-Kühler gestaltet ist. In seiner letztgenannten Funktion stellt der Kühler einen Ladeluftkühler dar. Durch die erfindungsgemäße Lösung ist es möglich, auch in Sammelkästen, die ohne das Vorsehen eines zusätzlichen Rohrbodens direkt auf aufgeweitete Rohrenden des Rippen/Rohrblockes aufgesetzt sind, Unterteilungen mittels wenigstens einer Trennwand vorzusehen, was bei Wärmeübertragern mit Rohrböden grundsätzlich bereits bekannt war. Die Trennwand nach der erfindungsgemäßen Lösung ist derart gestaltet, daß die Trennwand bereits bei der Vormontage des gesamten Wärmeübertragers integriert werden kann und anschließend im Lötofen gemeinsam mit den übrigen Teilen des Wärmeübertragers in einem gemeinsamen Lötprozeß dicht mit dem Sammelkasten und den jeweiligen Rohrenden verbunden werden kann. Durch den Haltefuß kann die Trennwand in einfacher Weise vor dem Aufsetzen des Sammelkastens auf die jeweiligen Wandungsabschnitte der entsprechenden Rohrenden aufgesteckt werden.This object is achieved in that in at least one Collection box at least one dividing the collection box Partition is provided, which in its outer contour matched an inner contour of a wall of the collecting tank is that it can be soldered tightly all around to the inner contour is, and the a support foot for attaching the partition two adjacent wall sections adjoining one another Has tube ends of the tube end package. By the Provide at least one partition in one of the two collection boxes it is possible to keep the flow medium inside the Redirect ribs / tube block U-shaped, creating the connections for the supply and discharge of the flow medium only one of the water boxes can be provided. The collection boxes depending on their connection to the corresponding Fluid medium circuit on collector or distributor function. Coolant, water, in particular, can be used as the flow medium or air can be provided, the heat exchanger in particular as coolant / air-water / air or air / air cooler is designed. In his latter role the cooler represents an intercooler Solution it is possible, even in collection boxes that without the need for an additional tube sheet widened pipe ends of the fins / pipe block placed are to provide subdivisions by means of at least one partition, which is basically the case with heat exchangers with tube plates was already known. The partition according to the invention Solution is designed so that the partition is already at the pre-assembly of the entire heat exchanger can be integrated can and then in the soldering furnace together with the rest Share the heat exchanger in a common soldering process tightly with the collecting box and the respective pipe ends can be connected. The partition can be held in place using the holding foot in a simple way before putting on the collection box the respective wall sections of the corresponding pipe ends be plugged on.

In Ausgestaltung der Erfindung weist der Haltefuß wenigstens eine einstückig angeformte, stegartige Lasche auf, die unter Bildung eines Aufnahmeschlitzes von der Trennwand abragt. Der Aufnahmeschlitz ist derart gestaltet, daß die Trennwand vor der Verlötung längs der Wandungsabschnitte in unterschiedlichen Positionen aufgesetzt und gegebenenfalls sogar relativ zu den Wandungsabschnitten der Rohrenden für eine Justierung verschoben werden kann.In an embodiment of the invention, the holding foot has at least a one-piece, web-like tab on the under Formation of a receiving slot protrudes from the partition. Of the Recording slot is designed so that the partition in front the soldering along the wall sections in different Positions put on and possibly even relative to the wall sections of the pipe ends for adjustment can be moved.

In weiterer Ausgestaltung der Erfindung ist der Haltefuß mit Zentrierschrägen zum Aufstecken auf die Wandungsabschnitte der Rohrenden versehen. Durch diese Zentrierschrägen wird das Aufstecken der Trennwand auf die Wandungsabschnitte der korrespondierenden Rohrenden vereinfacht. Durch den Haltefuß ist die Trennwand kraftschlüssig auf den zugeordneten Rohrenden gehalten.In a further embodiment of the invention, the holding foot is included Centering bevels for attaching to the wall sections the pipe ends. Because of these centering bevels Attach the partition to the wall sections of the corresponding ones Pipe ends simplified. Through the holding foot is the partition non-positively on the assigned pipe ends held.

In weiterer Ausgestaltung der Erfindung weist die Trennwand in Abstand zu dem Haltefuß wenigstens eine Fixiernase auf, die im montierten Zustand der Trennwand in eine korrespondierende Aussparung in der Wandung des Sammelkastens hineinragt. Dadurch wird eine zusätzliche formschlüssige Fixierung der Trennwand an dem Sammelkasten erzielt, wodurch eine äußerst stabile Unterteilung des Sammelkastens erfolgt. Dadurch ist es möglich, Strömungen innerhalb des Wärmeübertragers auch mit hohem Druck zuzulassen, da die Trennwand sowohl am Sammelkasten als auch an den Wandungsabschnitten der zugeordneten Rohrenden formschlüssig gehalten ist. Auch die Fixiernase ist wie die Lasche am Haltefuß einstückig angeformt, so daß die Trennwand als einfaches Blechstanzteil gestaltet werden kann.In a further embodiment of the invention, the partition wall at least one fixing lug at a distance from the holding foot, in the assembled state of the partition into a corresponding one Recess protrudes into the wall of the collection box. This creates an additional positive fixation of the Partition achieved on the collection box, making an extremely stable subdivision of the collection box takes place. This is it is possible to have flows within the heat exchanger as well with high pressure because the partition is both on the collecting box as well as on the wall sections of the assigned Pipe ends is held positively. Also the fixing nose is integrally molded like the tab on the holding foot, so that the partition can be designed as a simple sheet metal stamped part can.

In weiterer Ausgestaltung der Erfindung ist die Fixiernase mit wenigstens einer verformbaren Ausstellecke versehen, die im montierten Zustand der Trennwand durch die Aussparung der Wandung des Sammelkastens hindurchragt und die derart verformt ist, daß sie einen Rand der Aussparung auf der Außenseite des Sammelkastens formschlüssig hintergreift. Dadurch ist es möglich, bereits vor der Verlötung des gesamten Wärmeübertragers den Formschluß zwischen der Trennwand und dem Sammelkasten zu erhöhen, indem in einfacher Weise die Ausstellecke umgebogen wird, wodurch sich eine Verkrallung auf der Außenseite des Sammelkastens ergibt. Vorzugsweise sind der Fixiernase auf gegenüberliegenden Seiten zwei Ausstellecken zugeordnet, die entgegengesetzt zueinander, jedoch im gleichen Uhrzeigersinn, verformt sind. Dadurch ergibt sich eine sichere Verkrallung der Trennwand am Sammelkasten vor der Verlötung, so daß die Trennwand im vormontierten Zustand des Wärmeübertragers, d.h. vor der Durchführung des Lötprozesses, bereits sicher und definiert positioniert ist.In a further embodiment of the invention, the fixing nose provided with at least one deformable display corner, the in the assembled state of the partition through the recess of the Wall protrudes through the collecting box and deformed in this way is that they have an edge of the recess on the outside of the collection box engages positively. Thereby it is possible even before the entire heat exchanger is soldered the positive connection between the partition and the Increase collection box by simply opening the display corner is bent, causing a claw on the outside of the collection box. Are preferred the fixing lug on two opposite sides assigned the opposite of each other, however in same clockwise, are deformed. This results in secure clawing of the partition on the collecting box the soldering, so that the partition in the pre-assembled state of the heat exchanger, i.e. before carrying out the soldering process, is already securely and clearly positioned.

Ein Wärmeübertrager, wie er anhand der Fig. 1 bis 4 ausschnittsweise dargestellt ist, ist als Wasser/Luft-Kühler gestaltet und entspricht in seinem grundsätzlichen Aufbau einem in der DE 195 43 986.4 beschriebenen Wärmeübertrager. Der Wasser/Luft-Kühler weist einen Rippen/Rohrblock F, W auf, der aus einer Vielzahl von zueinander parallel verlaufenden Flachrohren F sowie einer Vielzahl von zwischen diesen angeordneten Wellrippen W zusammengesetzt ist. Die Flachrohre F weisen auf gegenüberliegenden Seiten jeweils Rohrenden 5 auf, die derart aufgeweitet sind, daß die jeweils benachbarten Rohrenden 5 in einer gemeinsamen Flucht flächig aneinander anliegen. Jedes Rohrende 5 ist zu einem rechteckigen, lichten Querschnitt aufgeweitet, wobei die benachbarten Rohrenden 5 jeweils mit ihren Breitseiten aneinander anschließen und die Schmalseiten der Rohrenden 5 aufgrund der Anordnung aller Rohrenden 5 in einer gemeinsamen Flucht bündig und fluchtend aneinander anschließen. Auf die Rohrenden 5 auf den gegenüberliegenden Seiten des Rippen/Rohrblockes F, W ist jeweils ein als Sammelkasten dienender Wasserkasten 1 aufgesetzt, wobei die Wasserkästen 1 jeweils als zum Rippen/Rohrblock F, W und zu ihren Stirnseiten hin offene, U-artige Profile gestaltet sind. Die beiden Wasserkästen auf den gegenüberliegenden Seiten des Rippen/Rohrblockes F, W weisen jeweils im wesentlichen das gleiche Profil auf. Die beiden Wasserkästen unterscheiden sich lediglich dadurch, daß der eine Wasserkasten 1, der in den Fig. 1 bis 5 dargestellt ist, zwei Anschlußstutzen 2, 3 aufweist, von denen der eine Anschlußstutzen 2 eine Zuleitung des zu kühlenden Wassers und der andere Anschlußstutzen 3 eine Ableitung des mittels des Rippen/Rohrblockes F, W gekühlten Wassers definiert. Die Anschlüsse können jedoch auch umgekehrt definiert sein. Die Anschlüsse an den Kühlkreislauf sind somit lediglich an dem einen Wasserkasten 1 vorgesehen. Auf die aufgeweiteten Rohrenden 5 ist jeder Wasserkasten derart aufgesetzt, daß die Seitenwandungen jedes Wasserkastens die gegenüberliegenden Schmalseiten der Rohrenden übergreifen und bündig sowie flächig mit diesen abschließen. Im Bereich ihrer gegenüberliegenden Stirnseiten sind beide Wasserkästen durch entsprechende Fortsätze von Seitenteilen verschlossen, die den Rippen/Rohrblock F, W seitlich begrenzen und die Profile der Wasserkästen stirnseitig dicht abschließen. Sowohl die Wasserkästen als auch die Seitenteile und die Flachrohre F sowie die Wellrippen W sind aus Metall, vorzugsweise aus Aluminium, hergestellt und werden in einem gemeinsamen Lötvorgang dicht miteinander verlötet.A heat exchanger, such as a section of FIGS. 1 to 4 is designed as a water / air cooler and corresponds in its basic structure to one heat exchanger described in DE 195 43 986.4. Of the Water / air cooler has a fins / tube block F, W that from a variety of parallel to each other Flat tubes F and a variety of arranged between them Corrugated fins W is composed. The flat tubes F have tube ends 5 on opposite sides, which are expanded in such a way that the neighboring ones Pipe ends 5 flat against each other in a common escape issue. Each tube end 5 is a rectangular, clear Cross section widened, the adjacent pipe ends 5 connect each other with their broad sides and the Narrow sides of the tube ends 5 due to the arrangement of all Pipe ends 5 flush and aligned in a common escape connect to each other. On the pipe ends 5 on the opposite Sides of the fins / tube block are F, W respectively a serving as a collecting box water box 1, where the water boxes 1 each as for the fins / tube block F, W and U-shaped profiles that are open towards the front are. The two water boxes on the opposite Sides of the fins / tube block F, W each have essentially the same profile. Differentiate the two water boxes only in that the one water box 1, which is shown in FIGS. 1 to 5, two connecting pieces 2, 3, of which one connecting piece 2 has a feed line of the water to be cooled and the other connecting piece 3 a derivation of the by means of the fins / tube block F, W cooled water. The connections can, however can also be defined vice versa. The connections to the cooling circuit are therefore only on the one water tank 1 intended. Each water box is on the widened pipe ends 5 placed so that the side walls each The opposite narrow sides of the pipe ends overlap and finish flush and flat with these. Are in the area of their opposite end faces both water boxes through corresponding extensions of side parts closed off the fins / tube block F, W laterally limit and the profiles of the water tanks tight on the front to lock. Both the water boxes and the side parts and the flat tubes F and the corrugated fins W are made of metal, preferably made of aluminum, and are in one joint soldering process soldered tightly together.

Um einen U-förmigen Durchfluß des zu kühlenden Wassers durch den Wasser/Luft-Kühler hindurch, d.h. vom Anschlußstutzen in Form eines Eintrittsstutzens 2 aus durch eine erste Hälfte des Rippen/Rohrblockes hindurch zum gegenüberliegenden Wasserkasten und durch die andere Hälfte des Rippen/Rohrblockes wieder zurück zum Wasserkasten 1 und damit zu dem als Austrittsstutzen 3 dienenden Anschlußstutzen, zu ermöglichen, ist in dem Wasserkasten 1 auf halber axialer Länge - auf die Längserstreckung des Wasserkastens 1 bezogen - eine Trennwand 4 vorgesehen, die den Wasserkasten 1 in zwei Hälften unterteilt. Die Trennwand 4 bildet in nachfolgend näher beschriebener Weise einen dichten Abschluß mit dem Wasserkasten 1 und den zugehörigen Rohrenden 5, so daß eine sichere Abtrennung zwischen dem Strömungsraum in der ersten Hälfte des Wasserkastens 1 und dem Strömungsraum in der zweiten Hälfte des Wasserkastens 1 geschaffen wird.To a U-shaped flow of water to be cooled through the water / air cooler, i.e. from the connector in Form of an inlet connector 2 made by a first half of the fins / pipe block through to the opposite water tank and through the other half of the fins / tube block back to the water tank 1 and thus to the outlet nozzle 3 serving connecting pieces, to enable is in the water box 1 on half the axial length - on the Longitudinal extension of the water tank 1 related - a partition 4 provided that divides the water tank 1 into two halves. The partition 4 forms in the following Way a tight seal with the water box 1 and the associated pipe ends 5, so that a safe separation between the flow space in the first half of the water tank 1 and the flow space in the second half of the water tank 1 is created.

Die Trennwand 4 stellt eine im wesentlichen ebene Blechplatte dar, die ebenfalls vorzugsweise aus Aluminium hergestellt ist. Die Außenkontur der Trennwand 4 ist sowohl in ihrer Form als auch in ihrer Dimensionierung an eine Innenkontur des U-förmigen Profiles (Fig. 5) des Wasserkastens 1 angepaßt. Die Trennwand 4 liegt somit in ihrem in den Wasserkasten 1 eingesetzten Zustand mit ihrer Außenkontur umlaufend an der Innenkontur der Innenwandung des Wasserkastens 1 an. Die Außenkontur der Trennwand 4 ist aus Fig. 6 erkennbar, wobei zu berücksichtigen ist, daß die Trennwand 4 gegenüber der Darstellung des Profils des Wasserkastens 1 nach Fig. 5 um 180° gedreht ist.The partition 4 represents an essentially flat sheet metal plate are also preferably made of aluminum is. The outer contour of the partition 4 is both in shape as well as their dimensions to an inner contour of the U-shaped Profiles (Fig. 5) of the water tank 1 adapted. The Partition 4 is thus inserted in the water tank 1 Condition with its outer contour all around on the inner contour the inner wall of the water tank 1. The outer contour the partition 4 can be seen from FIG. 6, taking into account is that the partition 4 compared to the illustration of the profile of the water box 1 according to FIG. 5 rotated by 180 ° is.

Die Trennwand 4 weist einen Haltefuß 9 auf, der in die offenen Stirnseiten zweier benachbarter Rohrenden 5 hineinragt, die sich auf halber Breite des Rippen/Rohrblockes befinden (Fig. 1 bis 3). Dazu sind die die Außenkontur der Trennwand 4 definierenden, gegenüberliegenden Seitenränder in ihrem Fußbereich und damit auf Höhe des Haltefußes 9 mit jeweils einer Abstufung 17 (Fig. 6) versehen, die sich auf den oberen Stirnrändern der zugeordneten Rohrenden 5 im aufgesteckten Zustand der Trennwand 4 abstützen. Der Abstand der beiden Abstufungen 17 zueinander entspricht somit exakt den Innenabmessungen der durch die Rohrenden 5 definierten Öffnungen der Flachrohre F.The partition 4 has a holding foot 9, which in the open End faces of two adjacent pipe ends 5 protrude, which are halfway across the fins / tube block (Fig. 1 to 3). These are the outer contour of the partition 4 defining, opposite side edges in their foot area and thus at the level of the holding foot 9 with one each Gradation 17 (Fig. 6) provided, which is on the upper Front edges of the associated pipe ends 5 in the attached Support the condition of the partition 4. The distance between the two levels 17 to each other thus corresponds exactly to the internal dimensions of the openings defined by the tube ends 5 Flat tubes F.

Um eine kraftschlüssige Fixierung der Trennwand 4 auf den aneinanderliegenden, breitseitigen Wandungsabschnitten der benachbarten Rohrenden 5 zu ermöglichen, weist der Haltefuß 9 zudem eine einstückig angeformte und abgestuft abgebogene Stützlasche 10, 11 auf, die derart von der Trennwand 4 abragt, daß sich zwischen der Stützlasche 10 und der durch die Plattenform der Trennwand 4 definierten Ebene ein zu gegenüberliegenden Seiten hin offener Aufnahmeschlitz A ergibt (Fig. 7). Die unteren Stirnenden des Haltefußes 9 weisen sowohl im Bereich der Stützlasche 10 als auch im Plattenbereich der Trennwand 4 jeweils schräg nach außen gekrümmte Zentrierschrägen 11, 12 auf, die ein sicheres Aufstecken der Trennwand 4 auf die zugeordneten Wandungsabschnitte 8 der benachbarten Rohrenden 5 auch bei geringem axialem Versatz - in Längserstreckung des Wasserkastens 1 gesehen - ermöglichen.In order to hold the partition 4 in a force-fitting manner on the adjacent, broad wall sections of the neighboring To enable pipe ends 5, the holding foot 9 also a one-piece molded and graduated bent Support tab 10, 11, which protrudes from the partition 4, that between the support tab 10 and by the Plate shape of the partition 4 defined level to an opposite Opening slot A open on the sides results (Fig. 7). The lower ends of the holding foot 9 have both in the area of the support tab 10 as well as in the plate area the partition 4 each obliquely curved outward centering 11, 12, which securely attach the partition 4 on the assigned wall sections 8 of the neighboring ones Pipe ends 5 even with slight axial misalignment - in Seen longitudinal extension of the water tank 1 - allow.

Die Trennwand 4 wird zusätzlich zu ihrer im Bereich der linienförmigen Anlage ihrer Außenkontur erfolgenden dichten Verlötung mit der Innenwandung des Wasserkastens 1 formschlüssig am Wasserkasten 1 positioniert. Dazu sind zum einen zwei Positionierrippen 6, 7 vorgesehen, die sich U-förmig über die Innenwandung des Wasserkastens 1 erstrecken (Fig. 5) und von der Innenwandung aus nach innen abragen. Beide Positionierrippen 6, 7 sind wulstartig gestaltet. Beide Positionierrippen 6, 7 verlaufen in zueinander parallelen Radialebenen - auf eine entlang der Längserstreckung des Wasserkastens 1 verlaufende Längsachse des Wasserkastens 1 bezogen. Zwischen diesen Positionierrippen 6, 7 ist die Trennwand 4 durch zwei Stützränder 13 axial positioniert gehalten, die rechtwinklig von den gegenüberliegenden Seitenrändern der Außenkontur der Trennwand 4 fluchtend mit dieser Außenkontur abragen und die in ihrer Höhe derart auf den Abstand der beiden Positionierrippen 6, 7 zueinander abgestimmt sind, daß sie paßgenau zwischen den Positionierrippen 6, 7 gehalten sind. In einer Radialebene des Wasserkastens 1 und damit in der Ebene der Trennwand 4 sind die Stützränder 13 und damit auch die Trennwand 4 jedoch zwischen den Positionierrippen 6, 7 verschiebbar, die insoweit lediglich Linearführungen darstellen.The partition 4 is in addition to its in the area of the linear Creation of their outer contour, tight soldering with the inner wall of the water tank 1 form-fitting positioned on the water tank 1. On the one hand there are two positioning ribs 6, 7 provided, which are U-shaped over the Extend inner wall of the water tank 1 (Fig. 5) and from protrude from the inside wall. Both positioning ribs 6, 7 are designed like beads. Both positioning ribs 6, 7 run in mutually parallel radial planes - On one along the length of the water tank 1 extending longitudinal axis of the water tank 1 related. Between this positioning ribs 6, 7 is the partition 4 by two Support edges 13 held axially positioned, the right angle from the opposite side edges of the outer contour of the Partition 4 in alignment with this outer contour and the in height in such a way on the distance between the two positioning ribs 6, 7 are matched to each other so that they fit snugly between the positioning ribs 6, 7 are held. In a radial plane of the water tank 1 and thus in the level of Partition 4 are the support edges 13 and thus also the partition 4, however, can be moved between the positioning ribs 6, 7, which only represent linear guides.

Um die Trennwand 4 in ihrer in den Wasserkasten 1 eingesetzten Position zusätzlich zu fixieren, ist an einer dem Haltefuß 9 gegenüberliegenden Kopfseite der Trennwand 4 eine Fixiernase 14 vorgesehen, die sich in der Ebene der Trennwand 4 verlängert nach oben erstreckt. Dieser Fixiernase 14 ist im Wasserkasten 1 eine korrespondierende, schlitzförmige Aussparung 16 zugeordnet, durch die die Fixiernase 14 bis zur Außenseite des Wasserkastens 1 hindurchragt. Die Fixiernase 14 ist zudem auf ihren gegenüberliegenden Seiten mit jeweils einer Ausstellecke 15 versehen, die in einfacher Weise durch entsprechende, zur Außenseite des Wasserkastens 1 parallele Einschlitzungen der Fixiernase 14 von ihren gegenüberliegenden Seiten her geschaffen sind. Diese Ausstellecken 15 sind verformbar, wobei die Einschlitzungen vorzugsweise derart auf die Tiefe der Aussparung 16 im Wasserkasten 1 abgestimmt sind, daß die Ausstellecken 15 auf der Außenseite des Wasserkastens 1 jeweils zur Seite hin umgebogen werden können und so eine Verkrallung der Trennwand 4 mit dem Wasserkasten 1 bilden (Fig. 4). Bei der Darstellung nach Fig. 4 ist zu berücksichtigen, daß die dargestellte Draufsicht um 180° verdreht gegenüber den Darstellungen nach den Fig. 1 bis 3 gezeigt ist.To use the partition 4 in its in the water tank 1 The position must also be fixed on one of the holding feet 9 opposite head side of the partition 4 a fixing lug 14 provided in the plane of the partition 4th extended upward stretches. This fixing lug 14 is in the Water box 1 has a corresponding, slot-shaped recess 16 assigned by the fixing lug 14 to the outside of the water box 1 protrudes. The fixing nose 14 is also on their opposite sides with one each Exhibition corner 15 provided by in a simple manner corresponding, parallel to the outside of the water tank 1 Slits of the fixing lug 14 from their opposite Pages are created. These display corners 15 are deformable, the slots preferably being such the depth of the recess 16 in the water tank 1 matched are that the Ausstellcken 15 on the outside of the water tank 1 can be bent to the side and such a clawing of the partition 4 with the water tank 1 form (Fig. 4). 4, it must be taken into account that the top view shown rotates by 180 ° compared to the representations shown in FIGS. 1 to 3 is.

Zur Montage des Wasser/Luft-Kühlers und insbesondere zur Montage der Trennwand 4 innerhalb des Wasserkastens 1 wird zunächst die Trennwand 4 so weit in den Wasserkasten eingesetzt, bis die Fixiernase 14 durch die Aussparung 16 hindurchragt. Dabei wird die Trennwand 4 zwischen die beiden Positionierrippen 6, 7 eingeschoben und längs dieser Positionierrippen 6, 7 bis zur linienförmigen Anlage ihrer Außenkontur mit der Innenwandung des Wasserkastens 1 verschoben. Anschließend werden die Ausstellecken 15 vorzugsweise mittels eines Werkzeugs in Form einer Zange oder ähnlichem gemäß Fig. 4 umgebogen, wodurch sich die formschlüssige Fixierung der Trennwand 4 im Wasserkasten 1 ergibt. Beim anschließenden Aufsetzen des Wasserkastens 1 auf die aufgeweiteten Rohrenden 5 des Rippen/Rohrblockes F, W wird der Haltefuß 9 zwangsläufig auf die Wandungsabschnitte 8 der zugeordneten, benachbarten Rohrenden 5 so weit aufgesteckt, bis die Abstufungen 17 auf den oberen Stirnrändern des jeweiligen Rohrendes anschlagen. Nach dem Anbringen der Seitenteile kann der solchermaßen vormontierte Wasser/Luft-Kühler in einfacher Weise in einem Lötofen durch einen einzigen Lötprozeß dicht verlötet werden. For mounting the water / air cooler and especially for mounting the partition 4 inside the water box 1 will initially the partition 4 inserted so far in the water tank, until the fixing lug 14 protrudes through the recess 16. The partition 4 is between the two positioning ribs 6, 7 inserted and along these positioning ribs 6, 7 to the linear shape of their outer contour moved with the inner wall of the water tank 1. Subsequently the display corners 15 are preferably by means of a tool in the form of pliers or the like according to FIG. 4 bent, whereby the positive fixation of the Partition 4 in the water tank 1 results. At the subsequent Place the water box 1 on the widened pipe ends 5 of the fins / tube block F, W, the holding foot 9 is inevitable on the wall sections 8 of the associated, adjacent Pipe ends 5 pushed on until the gradations 17th strike on the upper end edges of the respective pipe end.
