Description

Anordnung zur Befestigung eines Wärmeübertragers an einem anderenArrangement for attaching one heat exchanger to another
Die Erfindung betrifft eine Anordnung zur Befestigung eines ersten Wärmeübertrages an einem zweiten Wärmeübertrager nach dem Oberbegriff des Patentanspruches 1.The invention relates to an arrangement for fastening a first heat transfer to a second heat exchanger according to the preamble of patent claim 1.
Die gegenseitige Befestigung von Wärmeübertragern ist insbesondere bei so genanten Kühlmodulen oder Frontends von Kraftfahrzeugen bekannt. Ein Kühlmodul, welches im vorderen Motorraum des Kraftfahrzeuges angeordnet ist, umfasst üblicherweise einen Kühlmittelkühler, einen Ladeluftkühler. und/oder einen Kondensator, welche untereinander befestigt werden und somit eine Baueinheit bilden. Teilweise werden die Wärmeübertrager auch separat im Fahrzeug befestigt, wie es durch die EP-A 915 308 für einen Kältemittel kondensator einer Kraftfahrzeug-Klimaanlage bekannt wurde. Der Kältemittel kondensator besteht aus einem gelöteten Rohr/Rippen-Block mit Rohrenden, welche in beiderseitig angeordnete Sammelrohre münden und mit diesen ebenfalls verlötet sind. Der Ein- und Austritt von Kältemittel erfolgt über so genannte Blockanschlüsse, die mit den Sammelrohren verlötet sind. Zur Befestigung des Kondensators sind am Rohr/Rippen-Block vier Haltee- lemente angeordnet, mit denen der gesamte Kondensator im Fahrzeug befestigt wird , meistens vor einem Kühlmittelkühler. Der bekannte Kondensator weist zusätzlich zu den Sammelrohren einen Sammelbehälter auf, der als integrierter Sammelbehälter durch die DE-A 42 38 853 der Anmelderin bekannt wurde. Dabei ist der Sammelbehälter oder Sammler direkt mit einem der Sammelrohre verbunden.The mutual attachment of heat exchangers is known, in particular, in cooling modules or front ends of motor vehicles. A cooling module, which is arranged in the front engine compartment of the motor vehicle, usually comprises a coolant cooler, an intercooler. and / or a capacitor, which are attached to one another and thus form a structural unit. In some cases, the heat exchangers are also fastened separately in the vehicle, as was known from EP-A 915 308 for a refrigerant condenser of a motor vehicle air conditioning system. The refrigerant condenser consists of a soldered tube / fin block with tube ends, which open into mutually arranged manifolds and are also soldered to them. Refrigerant enters and exits via so-called block connections, which are soldered to the header pipes. To hold the condenser, four holding elements are arranged on the tube / fin block, with which the entire condenser is fastened in the vehicle, usually in front of a coolant cooler. The known condenser has, in addition to the collecting pipes, a collecting container which has become known as an integrated collecting container by DE-A 42 38 853 of the applicant. The collecting container or collector is connected directly to one of the collecting pipes.
BESTATIGUNGSKOPIE Eine andere Kondensatorbefestigung wurde durch die DE-A 196 45 502 bekannt, und zwar ebenfalls für einen gelöteten Kondensator mit einem Rohr/Rippen-Block, bestehend aus Flachrohren und Kühlrippen. Zur Befesti- gung des bekannten Kondensators im Fahrzeug sind auf beiden Seiten des Rohr/Rippen-Blockes Halterungselemente in Form von Blechen mit Befestigungslaschen angeschraubt oder angenietet. Nachteilig bei den bekannten Kondensatorbefestigungen ist, dass diese zusätzliche Halterungsmittel benötigen, welche durch Schrauben, Nieten oder Klemmen mit dem Rohr/Rippen-Block verbunden werden.BESTATIGUNGSKOPIE Another condenser attachment was known from DE-A 196 45 502, also for a soldered condenser with a tube / fin block consisting of flat tubes and cooling fins. To fasten the known capacitor in the vehicle, mounting elements in the form of metal sheets with fastening straps are screwed or riveted onto both sides of the tube / fin block. A disadvantage of the known condenser attachments is that they require additional holding means which are connected to the tube / fin block by means of screws, rivets or clamps.
Bekannt ist auch, dass an die Sammelrohre Befestigungselemente angelötet werden, damit der Kondensator im Fahrzeug oder an einem benachbarten Wärmeübertrager befestigt werden kann, z. B. einem Kühlmittelkühler, wel- eher der Kühlung eines flüssigen Kühlmittels für die Brennkraftmaschine des Kraftfahrzeuges dient. Kühlmittelkühler sind anders aufgebaut als Kältemittelkondensatoren und weisen vielfach ein gelötetes Netz mit gelötetem Rohrboden sowie einen Kühlmittelkasten auf, der als Kunststoffspitzteil hergestellt ist und damit die Möglichkeit bietet, Kühlmittelstutzen und Befesti- gungselemente mit an den Kühlmittelkasten anzuspritzen. Dies wurde bekannt für die Befestigung von Lüfterhauben oder von Ladeluftkühlern. Dabei sind einerseits an der Lüfterhaube oder an den ebenfalls aus Kunststoff hergestellten Luftkästen der Ladeluftkühler entsprechende Befestigungselemente angespritzt, die mit den zugehörigen Befestigungselementen am Kühlmittelkasten verbunden oder verrastet werden. Da ein Kondensator keine Kunststoffkästen aufweist, sondern metallische Sammelrohre, ist ein Anspritzen von Befestigungselementen hier nicht möglich.It is also known that fastening elements are soldered to the header pipes so that the condenser can be fastened in the vehicle or on an adjacent heat exchanger, e.g. B. a coolant cooler, which rather serves to cool a liquid coolant for the internal combustion engine of the motor vehicle. Coolant coolers are constructed differently than refrigerant condensers and often have a soldered network with a soldered tube sheet and a coolant box, which is manufactured as a plastic tip and thus offers the possibility of spraying coolant sockets and fastening elements onto the coolant box. This became known for the attachment of fan hoods or intercoolers. Corresponding fastening elements are injection molded onto the fan hood or onto the air boxes of the intercooler, which are also made of plastic, and are connected or locked to the associated fastening elements on the coolant box. Since a condenser does not have plastic boxes, but rather metal manifolds, it is not possible to inject fastening elements here.
Es ist Aufgabe der vorliegenden Erfindung, eine Befestigung für zwei Wär- meübertrager der eingangs genannten Art zu schaffen, die möglichst ohne Zusatzteile für die Befestigung auskommt, mit geringen Kosten herstellbar und einfach montierbar ist.It is an object of the present invention to provide a fastening for two heat exchangers of the type mentioned at the outset, which, as far as possible, does not require any additional parts for the fastening, can be produced at low cost and is easy to assemble.
Diese Aufgabe wird durch die Merkmale des Patenanspruches 1 gelöst. Er- findungsgemäß ist vorgesehen, dass an die Sammelkästen des zweiten Wärmeübertragers Haltemittel angebracht, insbesondere angegossen oder angespritzt sind, mit denen der erste Wärmeübertrager am zweiten Wärmeübertrager befestigt wird. Damit wird der Vorteil erreicht, dass auf zusätzliche Befestigungsmittel, die an dem ersten Wärmeübertrager angeschraubt, an- genietet oder angelötet sind, verzichtet werden kann. Dies vereinfacht den Aufbau des ersten Wärmeübertragers und senkt die Herstellungskosten. Darüber hinaus wird die Montage vereinfacht, weil Verschraubungen und dergleichen entfallen.This object is achieved by the features of patent claim 1. According to the invention, it is provided that the collecting boxes of the second Heat exchanger holding means attached, in particular cast or injection molded, with which the first heat exchanger is attached to the second heat exchanger. This has the advantage that there is no need for additional fastening means which are screwed, riveted or soldered to the first heat exchanger. This simplifies the construction of the first heat exchanger and lowers the manufacturing costs. In addition, assembly is simplified because screw connections and the like are eliminated.
Nach einer vorteilhaften Ausgestaltung der Erfindung wird der erste Wärmeübertrager an vier Eckbereichen gehalten, und die angespritzten Haltemittel am zweiten Wärmeübertrager sind an die Form des ersten Wärmeübertragers angepasst, sodass sich ein Form- und/oder Kraftschluss ergibt. Vorteilhafterweise wird dies durch angespritzte Haken im oberen Bereich der Sammelkästen des zweiter! Wärmeübertragers erreicht. Diese Ausbildung erlaubt ein Einschieben des ersten Wärmeübertragers von unten in die oben angeordneten Haken.According to an advantageous embodiment of the invention, the first heat exchanger is held at four corner regions, and the molded-on holding means on the second heat exchanger are adapted to the shape of the first heat exchanger, so that a positive and / or non-positive connection results. This is advantageously done by molded hooks in the upper area of the collecting boxes of the second! Heat exchanger reached. This design allows the first heat exchanger to be inserted from below into the hooks arranged at the top.
In weiterer vorteilhafter Ausgestaltung der Erfindung sind die unteren Befe- stigungselemente am zweiten Wärmeübertrager als rippenförmϊger Absatz mit Schnapphaken ausgebildet, ebenfalls an einen der Sammelkästen angespritzt. Damit wird einerseits eine sichere Auflage des ersten Wärmeübertragers (Fixierung in der Senkrechten) und zweitens eine Fixierung durch den Schnapphaken in der Waagerechten erreicht.In a further advantageous embodiment of the invention, the lower fastening elements on the second heat exchanger are designed as a rib-shaped shoulder with snap hooks, likewise molded onto one of the header boxes. On the one hand, a secure support of the first heat exchanger (fixation in the vertical) and, on the other hand, a fixation by the snap hook in the horizontal is achieved.
In weiterer vorteilhafter Ausgestaltung der Erfindung ist an dem ersten Wärmeübertrager, d. h. an dessen Sammelrohren ein so genannter Blockan- schluss befestigt, der als Verankerungselement des ersten Wärmeübertragers am zweiten Wärmeübertrager dient. Der Blockanschluss wird von ei- nem angespritzten Haken umfasst und von einem Schnapphaken gehalten. Damit ist der erste Wärmeübertrager ohne Zusatzteil hinreichend am zweiten Wärmeübertrager befestigt. Als Vorteil ergibt sich ferner eine einfache Montage durch geneigtes Einschieben des ersten Wärmeübertragers von unten in die oberen Haken und anschließendes Beiklappen an den zweiten Wärmeübertrager, bis die beiden unteren Schnapphaken einrasten und den ersten Wärmeübertrager somit in den Horizontalen verriegeln.In a further advantageous embodiment of the invention, a so-called block connection, which serves as an anchoring element of the first heat exchanger on the second heat exchanger, is fastened to the first heat exchanger, that is to say to its manifolds. The block connection is encased by a molded hook and held by a snap hook. The first heat exchanger is thus sufficiently fastened to the second heat exchanger without an additional part. Another advantage is a simple assembly by sloping insertion of the first heat exchanger from below into the upper hooks and subsequent folding onto the second Heat exchanger until the two lower snap hooks engage and thus lock the first heat exchanger horizontally.
Nach einer weitern vorteilhaften Ausgestaltung der Erfindung sind der erste Wärmeübertrager als Kondensator eines Kraftfahrzeuges und der zweite Wärmeübertrager als Kühlmittelkühler eines Kraftfahrzeuges ausgebildet, die vorteilhafterweise in einem Kühlmodul zusammen gefasst sind. Dabei ist der Kühlmittelkühler vorteilhafterweise der Modulträger, d. h. an ihm sind die anderen Komponenten befestigt. Der Kondensator, der aus Aluminium besteht und komplett in einem Lötofen gelötet wird, kann somit durch den Verzicht auf angelötete Haltemittel einfach gestaltet und mit niedrigen Kosten hergestellt werden. Der zusätzliche Aufwand für die Befestigungsmittel an den Kühlmittelkästen des Kühlers ist relativ gering und schlägt sich in einmaligen Kosten für das Kunststoffspritzwerkzeug der Sammelkästen nieder.According to a further advantageous embodiment of the invention, the first heat exchanger is designed as a condenser of a motor vehicle and the second heat exchanger is designed as a coolant cooler of a motor vehicle, which are advantageously combined in a cooling module. The coolant cooler is advantageously the module carrier, i. H. the other components are attached to it. The capacitor, which consists of aluminum and is completely soldered in a soldering furnace, can thus be designed simply by dispensing with soldered holding means and can be produced at low cost. The additional effort for the fasteners on the coolant boxes of the cooler is relatively small and is reflected in one-off costs for the plastic injection mold of the collecting boxes.

Die Luftströmungsrichtung ist durch einen Pfeil L eingezeichnet. In Luftströmungsrichtung vor dem Kühler 2 ist ein Kältemittelkondensator 11 angeordnet und - auf unten zu erläuternde Weise - mit dem Kühler 2 verbunden. Der Kondensator 11 weist einen aus nicht dargestellten Flachrohren und Wellrippen gelöteten Kondensatorblock 12 sowie beidersei- tig zwei Sammelrohre auf, von denen hier nur das linke Sammelrohr 13 sichtbar ist, welches mit einem Sammler 14 integriert ist. Derartige Kondensatoren mit integriertem Sammler sind aus dem eingangs zitierten Stand der Technik, d. h. der DE-A 42 38 853 bekannt.FIG. 1 a shows the cooler according to FIG. 1 in a view from above, the direction of travel X and the transverse direction Y being drawn in as coordinates on the right. The direction of air flow is shown by an arrow L. A refrigerant condenser 11 is arranged in the air flow direction in front of the radiator 2 and is connected to the radiator 2 in a manner to be explained below. The condenser 11 has a condenser block 12 soldered from flat tubes and corrugated fins, not shown, and on both sides two header tubes, of which only the left header tube 13 is visible, which is integrated with a header 14. Such capacitors with an integrated collector are from the prior art cited at the beginning, i. H. DE-A 42 38 853 known.
Fig. 2 zeigt eine Seitenansicht des Kühlers 1 von links mit in Luftströmungsrichtung vorgeschaltetem Kondensator 11 , von dem im Wesentlichen nur der Sammler 14 zu sehen ist. Am Kühlmittelkasten 4 ist der Haltezapfen 9, in Luftströmungsrichtung etwas nach rechts versetzt, angeordnet. Der Sammelbehälter 14 liegt parallel am Kühlmittelkasten 4 an und ist in Y-Richtung (senkrecht zur Zeichenebene) durch eine am Kühlmittelkasten 4 angespritzte bügeiförmige Rippe 15 fixiert. Am oberen Ende des Kühlmittelkastens 4 ist ein nach unten weisender Haken 16 angespritzt, der den oberen Teil 14a des Sammlers 14 übergreift, ihn in X-Richtung fixiert und in Z-Richtung einen Toleranzausgleich zulässt. Der Kühlmittelkasten 4 weist in seinem unteren Bereich einen angespritzten rippenförmigen Absatz 17 auf, an welchen sich ein Schnapphaken 18 in X-Richtung anschließt. Der untere Teil 14b des Sammlers 14 liegt auf dem Absatz 17 auf, ist damit in Z-Richtung fixiert und wird durch den Schnapphaken 18 in X-Richtung gehalten. Unterhalb des Schnapphakens 18 ist eine biegesteife Rippe 19 zur Sicherung des Schnapphakens 18 gegen Überbiegen angeordnet. Unterhalb der Rippe 19 ist ein Blockanschluss 20 mit zwei Anschlussbohrungen 20a, 20b erkennbar, welcher mit dem Sammelrohr verbunden ist, welches auf der dem Sammler 14 abgewandten Seite des Kondensatorblockes angeordnet ist. Der Blockanschluss 20 wird von einem Haken 21 umfasst, welcher an den Kühlmittel- kästen 4 angespritzt ist und den Kondensator in Z-Richtung festlegt.2 shows a side view of the cooler 1 from the left with the condenser 11 connected upstream in the air flow direction, of which essentially only the collector 14 can be seen. The holding pin 9 is arranged on the coolant box 4, offset somewhat to the right in the air flow direction. The collecting container 14 lies parallel to the coolant box 4 and is fixed in the Y direction (perpendicular to the plane of the drawing) by a bow-shaped rib 15 molded onto the coolant box 4. A downward-pointing hook 16 is molded onto the upper end of the coolant box 4, which engages over the upper part 14a of the collector 14, fixes it in the X direction and permits tolerance compensation in the Z direction. The coolant box 4 has in its lower area an injection molded rib-shaped shoulder 17, on which a snap hook 18 connects in the X direction. The lower part 14b of the collector 14 rests on the shoulder 17, is thus fixed in the Z direction and is held in the X direction by the snap hook 18. A rigid rib 19 for securing the snap hook 18 against bending over is arranged below the snap hook 18. Below the rib 19, a block connection 20 with two connection bores 20a, 20b can be seen, which is connected to the collecting pipe, which is arranged on the side of the condenser block facing away from the collector 14. The block connection 20 is encompassed by a hook 21 which is molded onto the coolant boxes 4 and fixes the condenser in the Z direction.
Fig. 2a zeigt die Seitenansicht gemäß Fig. 2 etwas um eine Hochachse (parallel zur Z-Achse) gedreht, d. h. in einer 3-D-Darstellung, wobei für gleiche Teile gleiche Bezugszahlen verwendet werden. Man erkennt den oberen Teil des Kondensatorblockes 12 und den Sammler 14, dessen oberer Teil 14a von dem Haken 16 übergriffen wird. Der untere Teil 14b des Sammlers 14 wird durch den Schnapphaken 18 nach vorne gesichert und durch die untere Rippe 19 gegen ein Überbiegen geschützt.FIG. 2a shows the side view according to FIG. 2 rotated somewhat about a vertical axis (parallel to the Z axis), i. H. in a 3-D representation, the same reference numbers being used for the same parts. The upper part of the capacitor block 12 and the collector 14 can be seen, the upper part 14a of which is overlapped by the hook 16. The lower part 14b of the collector 14 is secured to the front by the snap hook 18 and protected against overbending by the lower rib 19.
Fig. 3 zeigt den Kühlmittelkühler 1 gemäß Fig. 1, in einer Seitenansicht von rechts, d. h. mit Blick auf den rechten Kühlmittelkasten 3, parallel zu welchem ein zweites Sammelrohr 22 angeordnet ist. Am unteren Ende des Sammelrohres 22 ist - wie bereits erwähnt - der Blockanschluss 20 befestigt, d. h. angelötet. Derartige Kältemittelanschlüsse sind aus dem eingangs genannten Stand der Technik bekannt; sie sind für den Anschluss einer nicht dargestellten Kältemittelzufluss- und -abflussleitung vorgesehen. Abweichend vom Stand der Technik ist der Blockanschluss 20 am Ende, d. h. einer Stirnfläche des Sammelrohres 22 angeordnet, und bildet somit eine Verankerung, durch welche der Kondensator 11 am Kühler 1 bzw. dessen Kühlmittelkasten 3 fixiert werden kann. Dazu ist - wie bereits erwähnt - einerseits der Haken 21 am Kühlmittelkasten 3 angespritzt und andererseits ein Schnapphaken 23 in Z-Richtung oberhalb des Blockanschlusses 20 vorgesehen (ebenfalls am Kühlmittelkasten 3 angespritzt), welcher in eine entsprechende Vertiefung 24 im Blockanschluss 20 eingreift und damit den Kondensator in X-Richtung sichert. Die dem Blockanschluss 20 entgegenge- setzte Seite des Sammelrohres 22 wird von einem am Kühlmittelkasten 3 angespritzten Haken 25 übergriffen, welcher das Sammelrohr 22 und damit den Kondensator 11 in X-Richtung hält.FIG. 3 shows the coolant cooler 1 according to FIG. 1 , in a side view from the right, ie with a view of the right coolant box 3, parallel to which a second header pipe 22 is arranged. As already mentioned, the block connection 20 is fastened, ie soldered, to the lower end of the collecting tube 22. Such refrigerant connections are known from the prior art mentioned at the beginning; they are intended for the connection of a refrigerant inflow and outflow line, not shown. In a departure from the prior art, the block connection 20 is arranged at the end, that is to say an end face of the collecting tube 22, and thus forms an anchorage by means of which the condenser 11 can be fixed to the cooler 1 or its coolant box 3. For this purpose - as already mentioned - on the one hand the hook 21 is molded onto the coolant box 3 and on the other hand a snap hook 23 is provided in the Z direction above the block connection 20 (also molded onto the coolant box 3), which engages in a corresponding recess 24 in the block connection 20 and thus the Secures capacitor in the X direction. The opposite of the block connection 20 set side of the collector pipe 22 is overlapped by a molded on the coolant box 3 hook 25, which holds the collector pipe 22 and thus the condenser 11 in the X direction.
Fig. 3a zeigt die Seitenansicht gemäß Fig. 3 etwas um eine Hochachse (parallel zur Z-Achse) geschwenkt, sodass man den oberen Teil des Kondensatorblockes 12 sieht. Ferner sind der obere Haken 24 sowie die unteren Befestigungsmittel wie der Haken 21 und der Schnapphaken 23 deutlich zu erkennen. Schließlich ist auch der Befestigungszapfen 10, der einstückig mit dem Kühlmittelkasten 3 ausgebildet ist, dargestellt.FIG. 3a shows the side view according to FIG. 3 pivoted somewhat about a vertical axis (parallel to the Z axis), so that one can see the upper part of the capacitor block 12. Furthermore, the upper hook 24 and the lower fastening means such as the hook 21 and the snap hook 23 can be clearly seen. Finally, the fastening pin 10, which is formed in one piece with the coolant box 3, is also shown.
Die Montage der beiden Wärmeübertrager erfolgt in der nachfolgend beschriebenen Weise: zunächst wird der Kondensator 11 mit dem Kühlmittelkühler 1 dadurch verbunden, dass der Kondensator 11 leicht gekippt (um eine horizontale Achse) und mit seiner oberen Kante unter-die beiden oberen Haken 16 und 24 geschoben wird. Der Kondensator 11 wird dann an den Kühlmittelkühler 1 beigeklappt, sodass die untere Kante des Kondensators 11 einerseits auf dem rippenförmigen Ansatz 17 und dem Schnapphaken 18 und andererseits zwischen dem Haken 21 und dem Schnapphaken 22 zu liegen kommt. Nach dem Einrasten der beiden Schnapphaken 18 und 22 ist der Montagevorgang beendet. Um eine spielfreie Anlage des Kondensators 11 bzw. des Sammlers 14 am Kühlmittelkasten 4 zu gewährleisten, sind an letzterem nicht näher dargestellte Auflagerippen angeordnet, und zwar im Bereich des oberen Drittels des Kühlmittelkastens 4 . The two heat exchangers are assembled in the manner described below: First, the condenser 11 is connected to the coolant cooler 1 by slightly tilting the condenser 11 (about a horizontal axis) and with its upper edge under the two upper hooks 16 and 24 is pushed. The condenser 11 is then folded onto the coolant cooler 1, so that the lower edge of the condenser 11 comes to rest on the one hand on the rib-shaped extension 17 and the snap hook 18 and on the other hand between the hook 21 and the snap hook 22. After the two snap hooks 18 and 22 have engaged, the assembly process is ended. In order to ensure that the condenser 11 and the collector 14 rest against the coolant box 4 without play, support ribs (not shown in more detail) are arranged on the latter, in the region of the upper third of the coolant box 4.
