Description

Die Erfindung betrifft ein Seitenteil für 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 side part for a heat exchanger with a finned tube block that is parallel to its two to the sides of the pipes with one side part each elastically deformable material is provided, which the outer Grip the ends of the ribs in a U-shape and through as Locking elements designed barbs in alignment with each other arranged recesses of the ribs are held, the the web connecting the barbs of the side parts convex to the Ribs are arched and in the installed state under tension abuts the ribs.

Ein Seitenteil 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 side part of this type is known from DE 196 05 909 A1. There you use the pretension of the web force created between the barbs to cause a unintentional loosening of the plastic Avoid side part. Despite this configuration the block brackets can be released by vibration, especially when the upstanding edges of the web serve to accommodate additional parts that are not immediate 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.FR-A-25 22 401 is a side part for a heat exchanger known, but only for the purpose serves, the sharp-edged rib ends protruding outwards cover so that no injuries occur to people, that handle the heat exchanger. Of course it should also damage the free ends of the thin ribs can be avoided. There you have a U-shaped profile Side part provided as protection, the thigh with inward facing ribs with a triangular cross section are provided. These ribs engage in the side Recesses in the ribs and thus ensure an elastic Seat of the side parts. Due to the design chosen there it is possible to easily assemble the side panels can. However, there is no firm hold of the side parts 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 a similar design are also known (FR-A-26 14 688), where the side parts are firmly attached to the ribs has anchored. There, the side parts are formed in two parts and can be compared to each other at the ends of the Slide on the ribs so that the protruding hooks fit into the corresponding Engage recesses in the ribs. Both components of the Side parts are then interlocked with one another secured in the assembly position by locking hooks. Such Types are complex.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Seitenteil 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 of the type mentioned, in which the connecting bridge later on the ends of the ribs for the barbs, convex to the ribs before assembly is to be designed so that a better holding stability the side parts is reached without a two-part Training and thus an increased installation effort necessary becomes.

Diese Aufgabe wird erfindungsgemäß bei einem Seitenteil der eingangs genannten Art dadurch gelöst, daß der Steg 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 with a side part of the type mentioned solved in that the web on both Provide ends with protruding side walls and by a second web connecting the side walls to form a hollow profile is supplemented, and that between the two webs at least a locking element is provided which the distance of the both bars fixed in the installed state.

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

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 development of the invention, the locking element as a locking element with two elastically interlocking Projections may be formed, the projections being advantageous are formed as strips, one of which is elastic separable locking edges for reaching behind Paragraphs on the other bar is provided. This configuration lets on the one hand the production of the hollow profile Extrude to, on the other hand, this also results a continuous locking of the two webs against each other inside 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 min dem Widerhaken möglichst steif ausgebildet sind. Diese Seitenteile werden bei ineinandergreifenden Verriegelungsleisten dann vor einem Lösen der Rastposition gesichert.In a development of the invention, the second web in the area the side walls have a smaller thickness than in the rest of the area have and it can also in the area of the locking bar be a little weaker. This configuration leads to a kind of hinge effect in the narrower Areas so that the second land on either side of the Bend in the middle from where its locking bar is arranged can be as if in the area of the locking bar and in the area of Side walls have hinges, whereas the one in between Area is stiff. This configuration therefore brings the Advantage with itself that the assembly in the installed state approximately rectangular cross-section hollow profile has two long sides arched away from each other, which the Folding in the side walls and the overlapping the rib ends Legs with barbs allowed. In further training the invention is to achieve such Panning effect when mounting advantageous if the side walls and those adjacent to it, overlapping the ribs Legs with the barb are as rigid as possible. These side parts are in interlocking locking bars then secured before releasing the locking position.

Die Fig. 1 zeigt ein erfindungsgemäßes 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 side part 1 according to the invention, the an elastic plastic is extruded and for adjustment to the length of the heat exchanger, not shown Length can be cut off. This side part 1 is intended according to FIG. 1 placed in the direction of arrow 2 on the ends 3a of ribs 3 be the finned tube block in a manner not shown form a heat exchanger consisting of several Pipes not shown is constructed, which is transverse to the Ribs 3 arranged parallel to one another run and on open ends in collection boxes, not shown. The side parts 1, of which run parallel to the tubes only one is also shown. This from a finned tube block The heat exchanger is formed by a cooling medium flowing through the collecting boxes and the pipes while air between the ribs 3 in a known manner flows when the heat exchanger e.g. as a cooler for one Motor vehicle engine is used.

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 on their two Outer edges have recesses 4, which run obliquely Form edges 4a, which are gripped by barbs 5 can be directed inwards at the end of legs 6 are arranged, which at about a right angle merge into a web 7, which is convex in relation to those facing it Ends 3a of the ribs 3 is curved. The web 7 goes laterally in upward-facing side walls 8, which in turn connected to each other by a second web 9 are, together with the web 7 and the two side walls 8 forms a hollow profile. The web 9 is in its central longitudinal plane 10 with a continuous bar 11 with a mushroom-shaped cross section. This bar 11 is in State of FIG. 1 also from the first web 7 ledge extending into the interior 12 of the hollow profile 13 opposite, which consists of two locking hooks 14 on their the mushroom head of the bar 11 opposite side with a Insertion bevels 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. When installing the side part 1, this side part is now 1 pressed in the direction of arrow 2 onto the ends 3a of the ribs 3, with the legs 6 under a further bulge bend the web 9 sideways and elastic into the Snap in recesses 4. This is the first assembly position reached, then continue in the direction of arrow 15 according to FIG. 2 pressed on the upper web 9 until this upper web 9 and the lower web 7 by resting on the ribs 3 in one shift approximately parallel to each other, the Mushroom head of the bar 11 pressed between the two locking hooks 14 and of these locking hooks, as shown in Fig. 2, is attacked. The hollow profile of the side part 1 has therefore in the attached position according to FIG. 2 approximately rectangular shape on; the arching of the webs before assembly 7 and 9, which were arched in opposite directions, no longer exist.

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 as in the mounting position according to FIG. 2 a strut that swings back the legs 6 and the side walls 8 prevented in the position shown in FIG. 1. Around To ensure effectiveness, it is provided that the second web 9 in the area of its center and the side walls 8 each have a thickness a or b, which is smaller than the thickness c of the web 9 in the area between them Edge areas to the side walls 8 (thickness a) or to the Locking bar 11 (thickness b). In the manufacture of the Hollow profile for the side part 1 is also useful to ensure that the wall thickness d of the side walls 8 and the wall thickness e of the legs 6 with the barbs 5 if possible is made large, so that if possible one Prevention of deformation from the assembly position according to FIG. 2 becomes. The edge areas of the web 9 with the thickness a or b act against it, as also from FIG. 1 in comparison to FIG. 2 can be seen in the type of hinges. In the assembly position the web 9 therefore supports the side walls and over them also the legs 9 against pivoting back. The new Side part, which thus forms a box-like hollow profile, enables hence the maintenance of extraordinarily high ones Fastening forces that secure the side part 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 hold can ultimately also be used to the side part 1 'of FIG. 3 still other holding functions assign without the attachment of the side part being affected. As can be seen, the hollow profile of the side part 1 'laterally with a protruding double-walled Edge 16 provided, which is in one piece with the hollow profile of the side part 1 'is made. Otherwise, the side part 1 'designed as the side part 1 of FIGS. 1 and 2 and is also assembled in the same way. On this edge 16 can, because of the excellent attachment of the side part, Additional units or parts can be arranged not be placed directly next to the heat exchanger should or can.
