Description

Die Erfindung betrifft einen Wärmeübertrager mit einem Rippenrohrblock, der an seinen beiden parallel zu den Rohren verlaufenden Seiten mit je einem Seitenteil aus elastisch verformbarem Material versehen ist, welche die äußeren Enden der Rippen U-förmig übergreifen und durch als Rastelemente ausgebildete Widerhaken in fluchtend zueinander angeordneten Ausnehmungen der Rippen gehalten sind, wobei der die Widerhaken verbindende Steg der Seitenteile konvex zu den Rippen gewölbt ist und in eingebautem Zustand unter Vorspannung an den Rippen anliegt.The invention relates to a heat exchanger with a Finned tube block, at its two parallel to the tubes extending sides, each with a side part made of elastic deformable material is provided, which the outer ends the ribs overlap U-shaped and by as locking elements trained barbs arranged in alignment with each other Recesses of the ribs are held, whereby the the barbs connecting web of the side parts convex to the ribs arched is in the installed state under bias to the Ribs rests.

Ein Wärmeübertrager mit Seitenteilen dieser Art ist aus der DE 196 05 909 A1 bekannt. Dort nützt man die durch die Vorspannung des Steges zwischen den Widerhaken entstehende Kraft dazu aus, um ein unbeabsichtigtes Lösen des in der Regel aus Kunststoff bestehenden Seitenteils zu vermeiden. Trotz dieser Ausgestaltung kann sich die Blockverklammerung aber durch Erschütterung lösen, insbesondere wenn nach oben ragende Ränder des Steges zur Aufnahme von Zusatzteilen dienen, die nicht unmittelbar neben dem Rippenrohrblock liegen sollen.A heat exchanger with side parts of this kind is from the DE 196 05 909 A1. There one benefits by the bias of the bridge between the barbs arising force to do so, to prevent unintentional release of the usually Plastic to avoid existing side panel. Despite this Design, the block clamping but by shaking solve, especially when upstanding edges the bridge serve to accommodate additional parts that are not should lie next to the finned tube block.

Aus der FR-A-25 22 401 ist ein Seitenteil für einen Wärmeübertrager bekannt, das allerdings ausschließlich dem Zweck dient, die scharfkantig nach außen abstehenden Rippenenden abzudecken, so daß keine Verletzungen bei den Personen auftreten, die den Wärmeübertrager handhaben. Natürlich soll auch auf diese Weise eine Beschädigung der freien Enden der dünnen Rippen vermieden werden. Dort hat man ein im Profil U-förmiges Seitenteil als Schutz vorgesehen, dessen Schenkel mit nach innen gerichteten Rippen mit einem Dreieckquerschnitt versehen sind. Diese Rippen greifen in seitlichen Ausnehmungen der Rippen ein und sichern so einen elastischen Sitz der Seitenteile. Durch die dort gewählte Ausgestaltung wird es zwar möglich, die Seitenteile leicht montieren zu können. Ein fester Halt der Seitenteile wird dort aber nicht erreicht.From FR-A-25 22 401 is a side part for a heat exchanger known, but only for the purpose serves, the sharp-edged outwardly projecting rib ends cover so that no injuries occur to the persons which handle the heat exchanger. Of course you should also in this way damaging the free ends of the thin ribs are avoided. There you have a U-shaped profile Side part provided as protection, whose legs with inwardly directed ribs with a triangular cross section are provided. These ribs engage in lateral Recesses of the ribs and thus secure an elastic Seat of the side panels. Due to the design chosen there Although it is possible to easily assemble the side panels too can. A firm hold of the side parts will not be there reached.

Es sind auch Wärmeübertrager ähnlicher Bauart bekannt (FR-A-26 14 688), bei denen man die Seitenteile fest an den Rippen verankert hat. Dort sind die Seitenteile aber zweiteilig ausgebildet und lassen sich gegeneinander so auf die Enden der Rippen aufschieben, daß abstehende Haken in entsprechende Ausnehmungen der Rippen eingreifen. Beide Bestandteile der Seitenteile werden dann untereinander durch das Ineinandergreifen von Rasthaken in der Montagelage gesichert. Solche Bauarten sind aber aufwendig.Heat exchangers of similar design are also known (FR-A-26 14 688), where the side parts are firmly attached to the ribs anchored. There, however, the side parts are formed in two parts and let each other so on the ends of the Push ribs that protruding hooks into appropriate Recesses of the ribs intervene. Both components of the Side parts are then interlinked by the mesh secured by locking hooks in the mounting position. Such Designs are complicated.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Seitenteil für einen Wärmeübertrager der eingangs genannten Art, bei der also der später auf den Enden der Rippen aufliegende Verbindungssteg für die Widerhaken vor der Montage konvex zu den Rippen gewölbt ist, so auszugestalten, daß eine bessere Haltestabilität der Seitenteile erreicht wird, ohne daß eine zweiteilige Ausbildung und damit ein erhöhter Montageaufwand notwendig wird.The present invention is therefore based on the object a side part for a heat exchanger of the aforementioned Kind, in which case the later on the ends of the ribs resting connecting web for the barbs before assembly convex to the ribs is arched, so that a better holding stability of the side parts is achieved without a two-part training and thus an increased Installation effort is necessary.

Diese Aufgabe wird erfindungsgemäß bei einem Wärmeübertrager der eingangs genannten Art dadurch gelöst, daß der Steg der Seitenteile an beiden Enden mit abstehenden Seitenwänden versehen und durch einen zweiten die Seitenwände verbindenden Steg zu einem Hohlprofil ergänzt ist, und daß zwischen den beiden Stegen mindestens ein Verriegelungselement vorgesehen ist, das den Abstand der beiden Stege im eingebauten Zustand fixiert.This object is achieved according to the invention in a heat exchanger of the type mentioned solved in that the web of the Side parts at both ends provided with protruding side walls and by a second connecting the side walls Bridge is supplemented to a hollow profile, and that between the two webs provided at least one locking element is that the distance between the two webs in the installed state fixed.

Durch diese Ausgestaltung wirkt der äußere Steg des Hohlprofils im angebauten Zustand als Druckstrebe, die ein Lösen der Widerhaken sicher verhindert.By this configuration, the outer web of the hollow profile acts in the mounted state as a pressure strut, which is a loosening of Barbs safely prevented.

In Weiterbildung der Erfindung kann das Verriegelungselement als ein Rastelement mit zwei elastisch ineinandergreifenden Vorsprüngen ausgebildet sein, wobei die Vorsprünge vorteilhaft als Leisten ausgebildet sind, von denen eine mit elastisch auseinanderdrückbaren Rastkanten zum Hintergreifen von Absätzen an der anderen Leiste versehen ist. Diese Ausgestaltung läßt zum einen die Herstellung des Hohlprofiles durch Extrudieren zu, zum anderen ergibt sich auf diese Weise auch eine durchgehende Verriegelung der beiden Stege gegeneinander innerhalb des Hohlprofils.In a further development of the invention, the locking element as a locking element with two elastically interlocking Projections may be formed, wherein the projections advantageous are formed as strips, one of which is elastic auseinanderdrückbaren locking edges for engaging behind Paragraphs on the other bar is provided. This embodiment lets on the one hand, the production of the hollow section Extruding to, on the other hand arises in this way too a continuous locking of the two webs against each other within the hollow profile.

In Weiterbildung der Erfindung kann der zweite Steg im Bereich der Seitenwände eine geringere Dicke als im übrigen Bereich aufweisen und er kann auch im Bereich der Rastleiste etwas schwächer ausgebildet sein. Diese Ausgestaltung führt zu einer Art Scharnierwirkung in den schmäler ausgebildeten Bereichen, so daß der zweite Steg nach beiden Seiten von der Mitte aus, wo seine Rastleiste angeordnet ist, so abknicken kann, als wären im Bereich der Rastleiste und im Bereich der Seitenwände Scharniere vorhanden, wogegen der dazwischen liegende Bereich steif ist. Diese Ausgestaltung bringt daher den Vorteil mit sich, daß bei der Montage das im eingebauten Zustand etwa rechteckigen Querschnitt aufweisende Hohlprofil zwei voneinander weggewölbte Längsseiten aufweist, die das Einklappen der Seitenwände und der die Rippenenden übergreifenden Schenkel mit den Widerhaken ermöglicht. In Weiterbildung der Erfindung ist es zur Erzielung eines solchen Schwenkeffektes bei der Montage vorteilhaft, wenn die Seitenwände und die daran angrenzenden, die Rippen übergreifenden Schenkel mit dem Widerhaken möglichst steif ausgebildet sind. Diese Seitenteile werden bei ineinandergreifenden Verriegelungsleisten dann vor einem Lösen der Rastposition gesichert.In a further development of the invention, the second bridge in the area the side walls a smaller thickness than in the remaining area and he can also in the area of the locking bar be a little weaker. This embodiment leads to a kind of hinge effect in the narrower trained Areas, so that the second jetty on both sides of the Center off, where his locking bar is arranged, so kink can be as in the area of the locking bar and in the area of Sidewalls hinges present, whereas the intervening Area is stiff. This embodiment therefore brings the The advantage with it, that during assembly in the installed state approximately rectangular cross section having hollow profile has two mutually weggewölbte longitudinal sides, the Collapsing the side walls and the rib ends across Allows thighs with the barbs. In training The invention is to achieve such Swinging effect during assembly advantageous if the side walls and the adjoining, the ribs across Legs are formed as stiff as possible with the barb. These side parts become interlocking locking strips then secured against loosening the locking position.

Die Fig. 1 zeigt einen Wärmeübertrager mit einem Seitenteil 1, das aus einem elastischen Kunststoff extrudiert ist und zur Anpassung an die Länge des nicht näher gezeigten Wärmeübertragers auf Länge abschneidbar ist. Dieses Seitenteil 1 soll gemäß Fig. 1 im Sinn des Pfeiles 2 auf die Enden 3a von Rippen 3 aufgesetzt werden, die in nicht näher gezeigter Weise den Rippenrohrblock eines Wärmeübertragers bilden, der aus mehreren, nicht näher gezeigten Rohren aufgebaut ist, die quer zu den parallel zueinander angeordneten Rippen 3 verlaufen und an ihren offenen Enden in nicht gezeigte Sammelkästen münden. Parallel zu den Rohren verlaufen die Seitenteile 1, von denen ebenfalls nur eines dargestellt ist. Dieser so aus einem Rippenrohrblock gebildete Wärmeübertrager wird von einem Kühlmedium durch die Sammelkästen und die Rohre durchströmt, während zwischen den Rippen 3 hindurch in bekannter Weise Luft strömt, wenn der Wärmeübertrager z.B. als Kühler für einen Kraftfahrzeugmotor eingesetzt ist. Fig. 1 shows a heat exchanger with a side part 1, which is extruded from an elastic plastic and for adaptation to the length of the heat exchanger not shown in detail Can be cut to length. This side part 1 is in accordance with Fig. 1 in the direction of the arrow 2 on the ends 3a of Ribs 3 are placed, in a manner not shown in detail form the finned tube block of a heat exchanger, the off a plurality of pipes not shown in detail is constructed, the run transversely to the mutually parallel ribs 3 and at their open ends in collection boxes, not shown lead. Parallel to the tubes extend the side parts 1, of which only one is shown. This one off a finned tube block formed heat exchanger is of a Cooling medium flows through the collecting tanks and the pipes, while in between the ribs 3 in known Way, air flows when the heat exchanger is e.g. as a cooler is used for a motor vehicle engine.

Die Fig. 1 läßt erkennen, daß die Rippen 3 an ihren beiden Außenkanten Ausnehmungen 4 aufweisen, welche schräg verlaufende Kanten 4a bilden, die von Widerhaken 5 hintergriffen werden können, die am Ende von Schenkeln 6 nach innen gerichtet angeordnet sind, welche etwa unter einem rechten Winkel in einen Steg 7 übergehen, der konvex gegenüber den ihm zugewandten Enden 3a der Rippen 3 gewölbt ist. Der Steg 7 geht seitlich in nach oben weisende Seitenwände 8 über, die ihrerseits durch einen zweiten Steg 9 untereinander verbunden sind, der mit dem Steg 7 und den beiden Seitenwänden 8 zusammen ein Hohlprofil bildet. Der Steg 9 ist in seiner Mittellängsebene 10 mit einer durchgehenden Leiste 11 mit einem pilzförmigen Querschnitt versehen. Diese Leiste 11 liegt im Zustand der Fig. 1 einer sich vom ersten Steg 7 aus ebenfalls in den Innenraum 12 des Hohlprofil hereinerstreckenden Leiste 13 gegenüber, die aus zwei Rasthaken 14 besteht, die an ihrer dem Pilzkopf der Leiste 11 gegenüberliegenden Seite mit einer Einführschräge versehen sind.Fig. 1 shows that the ribs 3 at their two Outside edges have recesses 4, which are inclined Form edges 4a, which are engaged behind by barbs 5 can be at the end of thighs 6 inward which are approximately at a right angle go over into a bridge 7, the convex facing him Ends 3a of the ribs 3 is curved. The bridge 7 goes laterally in upwardly facing side walls 8, which in turn connected by a second web 9 with each other are, with the web 7 and the two side walls 8 together forms a hollow profile. The web 9 is in its central longitudinal plane 10 with a continuous bar 11 with a provided mushroom-shaped cross-section. This bar 11 is located in State of Fig. 1 a from the first web 7 also from in the interior 12 of the hollow profile inwardly extending bar 13 opposite, which consists of two latching hooks 14, at their the mushroom head of the bar 11 opposite side with a Insertion slope are provided.

Bei der Montage des Seitenteils 1 wird nun dieses Seitenteil 1 im Sinn des Pfeiles 2 auf die Enden 3a der Rippen 3 aufgedrückt, wobei sich die Schenkel 6 unter einer weiteren Aufwölbung des Steges 9 seitlich aufbiegen und elastisch in die Ausnehmungen 4 einschnappen. Ist diese erste Montagestellung erreicht, dann wird weiter im Sinn des Pfeiles 15 gemäß Fig. 2 auf den oberen Steg 9 gedrückt, bis sich dieser obere Steg 9 und der untere Steg 7 durch Auflage auf den Rippen 3 in eine etwa parallel zueinander verlaufende Lage verschieben, der Pilzkopf der Leiste 11 zwischen die beiden Rasthaken 14 eingedrückt ist und von diesen Rasthaken, wie in Fig. 2 gezeigt, hintergriffen wird. Das Hohlprofil des Seitenteils 1 weist daher in der angebauten Lage nach Fig. 2 etwa Rechteckform auf; die vor der Montage noch vorhandene Auswölbung der Stege 7 und 9, die gegensinnig gewölbt waren, ist nicht mehr vorhanden. During assembly of the side part 1 is now this side part 1 is pressed in the direction of the arrow 2 on the ends 3a of the ribs 3, wherein the legs 6 under another bulge of the web 9 bend laterally and elastically in the Snap recesses 4. Is this first assembly position reached, then continues in the direction of the arrow 15 of FIG. 2 pressed on the upper bridge 9 until this upper bridge 9 and the lower web 7 by resting on the ribs 3 in a move about parallel to each other running position, the Mushroom head of the bar 11 between the two locking hooks 14 is pressed is and of these latching hooks, as shown in Fig. 2, is engaged behind. The hollow profile of the side part 1 has Therefore, in the mounted position of FIG. 2 approximately rectangular shape on; the pre-assembly still existing bulge of the webs 7 and 9, which were arched in opposite directions, is no longer available.

Der zweite Steg 9 wirkt in der Montagelage nach Fig. 2 als eine Druckstrebe, die ein Rückschwenken der Schenkel 6 und der Seitenwände 8 in die Lage nach Fig. 1 verhindert. Um diese Wirkungsweise sicherzustellen, ist vorgesehen, daß der zweite Steg 9 jeweils im Bereich seiner Mitte und der Seitenwände 8 jeweils eine Dicke a bzw. b aufweist, die kleiner ist als die Dicke c des Steges 9 jeweils im Bereich zwischen diesen Randbereichen zu den Seitenwänden 8 (Dicke a) bzw. zu der Verriegelungsleiste 11 (Dicke b). Bei der Herstellung des Hohlprofiles für das Seitenteil 1 ist außerdem zweckmäßig darauf zu achten, daß die Wandstärke d der Seitenwände 8 und die Wandstärke e der Schenkel 6 mit den Widerhaken 5 möglichst groß gemacht wird, damit hier nach Möglichkeit eine Rückverformung aus der Montagelage nach Fig. 2 verhindert wird. Die Randbereiche des Steges 9 mit der Stärke a bzw. b wirken dagegen, wie auch aus Fig. 1 im Vergleich zu Fig. 2 erkennbar wird, in der Art von Scharnieren. In der Montagelage stützt der Steg 9 daher die Seitenwände und über diese auch die Schenkel 9 gegen eine Rückverschwenkung ab. Das neue Seitenteil, das also ein kastenartiges Hohlprofil bildet, ermöglicht daher die Aufrechterhaltung von außerordentlich hohen Befestigungskräften, die einen sicheren Halt des Seitenteils 1 bewirken.The second web 9 acts in the mounting position of FIG. 2 as a compression strut, the pivoting back of the legs 6 and the side walls 8 in the position of FIG. 1 prevented. Around To ensure effect, it is provided that the second web 9 each in the region of its center and the side walls 8 each has a thickness a or b, which is smaller as the thickness c of the web 9 respectively in the area between them Edge regions to the side walls 8 (thickness a) or to the Locking bar 11 (thickness b). In the production of the Hollow profiles for the side part 1 is also appropriate make sure that the wall thickness d of the side walls 8 and the wall thickness e of the legs 6 with the barbs 5 as possible is made large, so here if possible a Rebounding from the mounting position shown in FIG. 2 prevented becomes. The edge regions of the web 9 with the strength a or b on the other hand, as in FIG. 1 in comparison to FIG. 2 becomes recognizable, in the manner of hinges. In the mounting position Therefore, the web 9 supports the side walls and over this also the legs 9 against a Rückverschwenkung. The new Side part, which thus forms a box-like hollow profile, allows hence the maintenance of extraordinarily high Fixing forces, a secure hold of the side panel 1 effect.

Dieser sichere Halt kann schließlich auch dazu ausgenützt werden, um dem Seitenteil 1' nach Fig. 3 noch andere Haltefunktionen zuzuordnen, ohne daß die Befestigung des Seitenteils beeinflußt wird. Wie zu erkennen ist, ist das Hohlprofil des Seitenteiles 1' seitlich mit einem abragenden doppelwandigen Rand 16 versehen, der einteilig mit dem Hohlprofil des Seitenteils 1' hergestellt ist. Im übrigen ist das Seitenteil 1' wie das Seitenteil 1 der Fig. 1 und 2 ausgebildet und wird auch in der gleichen Weise montiert. An diesem Rand 16 können, wegen der ausgezeichneten Befestigung des Seitenteils, Zusatzaggregate oder Teile angeordnet werden, die nicht unmittelbar neben dem Wärmeübertrager angeordnet werden sollen oder können.This secure grip can finally be exploited be to the side part 1 'of FIG. 3 other holding functions assigned, without the attachment of the side part being affected. As can be seen, is the hollow profile of the side part 1 'laterally with a protruding double-walled Edge 16 provided, the one-piece with the hollow section of the side part 1 'is produced. Otherwise, the side panel 1 'as the side part 1 of FIGS. 1 and 2 formed and is also mounted in the same way. On this edge 16 can, because of the excellent attachment of the side part, Additional units or parts are arranged, the not be placed immediately adjacent to the heat exchanger should or can.
