On the outer sides of the two legs 11b, 11c, further likewise tapered holding elements 13 are arranged in vertical rows. Above the contact surface 11a, a cylindrical, ribbed pin 14 is arranged, which merges via a shoulder in a conical pin 15 of smaller diameter. These two pins 14, 15 are used to attach a heat exchanger, not shown, or not shown additional parts. The clamping element 10 is made as a one-piece plastic injection molded part.

Fig. 2a zeigt eine Ansicht von oben auf das zweite Klemmelement 10, wobei die kreisförmigen Querschnitte der Zapfen 14, 15 erkennbar sind. Seitlich weist das zweite Klemmelement 10 zwei Rastarme 16, 17 auf, deren Funktion unten erläutert wird. Fig. 2a shows a view from above of the second clamping element 10, wherein the circular cross-sections of the pins 14, 15 can be seen. Laterally, the second clamping element 10 has two latching arms 16, 17, whose function will be explained below.

Fig. 2b zeigt eine Ansicht von unten auf das zweite Klemmelement 10, wobei die dreieckige, spitz zulaufende Form der Haltelemente 12 sichtbar ist sowie die rechteckige Kontur der weiteren Haltelemente 13. 2b shows a view from below of the second clamping element 10, wherein the triangular, pointed shape of the holding elements 12 is visible and the rectangular contour of the further holding elements 13th

Fig. 2c zeigt eine Seitenansicht des zweiten Klemmelementes 10, wobei insbesondere die spitz zulaufende Form der Halteelemente 13 zu erkennen ist. Der obere Teil des zweiten Klemmelementes 10 mit dem Zapfen 14 ist als Einzelheit X in Fig. 2d dargestellt. Fig. 2c shows a side view of the second clamping element 10, wherein in particular the tapered shape of the holding elements 13 can be seen. The upper part of the second clamping element 10 with the pin 14 is shown as a detail X in Fig. 2d.

Fig. 2d zeigt also einerseits die beiden Zapfen 14, 15 und unterhalb einen der beiden Rastarme 16, 17, d. h. den Rastarm 16. Letzterer ist als federnde Zunge ausgebildet und weist an seinem freien Ende eine Rastnase 18 auf, und zwar mit einem nach oben (in Richtung der Zapfen 14, 15) gerichteten hakenförmigen Ansatz 18a. Fig. 2d thus shows on the one hand the two pins 14, 15 and below one of the two latching arms 16, 17, ie the latching arm 16. The latter is designed as a resilient tongue and has at its free end a latching lug 18, with one upwards (in the direction of the pins 14, 15) directed hook-shaped projection 18 a.

Fig. 3 zeigt die fertig montierten, miteinander verrasteten Klemmelemente 1, 10. Zwischen den beiden Anpressflächen 2, 11 ist gestrichelt ein Rohr/Rippenblock 19 mit Flachrohren 20 und einem Seitenteil 21 dargestellt, wobei sich zwischen den Flachrohren 20 sowie dem äußersten Flachrohr und dem Seitenteil 21 nicht dargestellte Wellrippen befinden, die mit den Flachrohren zu dem Rohr/Rippenblock 19 verlötet sind. Der Rastarm 16 ist in die Haltetasche 6 von der Stirnseite 6a her eingeführt und mit seiner Rastnase 18 auf der Rastfläche 8 der Haltetasche 6 verrastet, d. h. beide Klemmelemente 1, 10 sind miteinander verclipst und schließen den Rohr/Rippenblock 19 zwischen sich ein. Die Halteelemente 3, 4 sowie 13, 12 haben sich in die nicht dargestellten Wellrippen zwischen den Flachrohren 20 eingegraben und bewirken dadurch einen Formschluss zwischen den Klemmelementen 1, 10 und dem Rohr/Rippenblock 19, sodass der gesamte Halter nicht verrutschen kann. Wie bereits erwähnt, sind die Halteelemente entsprechend der Rohrteilung (Abstand der Flachrohre 20 zueinander) an den Anpressflächen angeordnet. Die beiden obersten Haltelemente 4, 13 liegen dabei mit ihren Oberkanten direkt an der Innenseite des Seitenteiles 21 des Rohr/Rippenblockes 19 an und bilden somit eine wirksame Verklammerung. Aus der Zeichnung wird ferner erkennbar, dass sich gegenüber liegende Halteelemente 4, 13 sowie 3, 12 den Rohr/Rippenblock 19 jeweils etwa bis zur Hälfte in seiner Tiefe durchdringen. Fig. 3 shows the fully assembled, latched together with each other clamping elements 1, 10. Between the two contact surfaces 2, 11, a tube / rib block 19 with flat tubes 20 and a side part 21 is shown in phantom, being between the flat tubes 20 and the outermost flat tube and the Side member 21 not shown corrugated fins are, which are soldered to the flat tubes to the tube / rib block 19. The latching arm 16 is inserted into the holding pocket 6 from the end face 6a ago and locked with its locking lug 18 on the locking surface 8 of the holding pocket 6, ie both clamping elements 1, 10 are clipped together and include the tube / rib block 19 between them. The holding elements 3, 4 and 13, 12 have buried in the corrugated fins between the flat tubes 20, not shown, thereby causing a positive connection between the clamping elements 1, 10 and the tube / rib block 19, so that the entire holder can not slip. As already mentioned, the holding elements are arranged according to the pipe pitch (distance between the flat tubes 20 to each other) to the contact surfaces. The two uppermost holding elements 4, 13 lie with their upper edges directly on the inside of the side part 21 of the tube / rib block 19 and thus form an effective clamping. It can also be seen from the drawing that opposing holding elements 4, 13 and 3, 12 each penetrate the tube / rib block 19 approximately halfway down its depth.

Die beiden Haltezapfen 14, 15 sind somit fest mit dem Rohr/Rippenblock 19 verbunden und können daher beispielsweise als Lagerzapfen, d.... h. zur Abstützung des Wärmeübertragers, z. B. eines Kondensators für eine Klimaanlage dienen. Die Zapfen 14, 15 können aber auch zur Aufnahme von Zusatzteilen, z. B. eines Anschlussflansches für Kältemittelanschlussleitungen verwendet werden.The two retaining pins 14, 15 are thus fixed to the tube / rib block 19th connected and therefore, for example, as a journal, d .... h. to Support of the heat exchanger, z. B. a condenser for an air conditioner serve. The pins 14, 15 but also for receiving Additional parts, eg. B. a connection flange for refrigerant connection lines be used.

Die Montage der beiden Klemmelemente 1, 10 ist denkbar einfach: zunächst wird das erste Klemmelement 1 mit seiner Anpressfläche 2 an eine erste Stirnfläche 19a angelegt, wobei die Haltetaschen 6 und die Anschlagleisten 5 auf dem Seitenteil 21 aufliegen. Das erste Klemmelement 1 wird dann gegen die Stirnfläche 19a gedrückt, sodass sich die Halteelement 3, 4 in die nicht dargestellten Rippen eingraben. Danach wird das zweite Klemmelement 10 in eine entsprechende, gegenüberliegende Position gebracht und mit seiner Anpressfläche 11 gegen die Stirnfläche 19b gedrückt, wobei die Rastnase 18 bereits in die Öffnung 6a der Haltetasche 6 eingeführt wird. Während der Andrückbewegung gleitet die Rastnase 18 auf der Rampe 7 und federt dabei (in der Zeichnung gesehen) nach unten. Am Ende der Andrückbewegung, d. h. wenn die Anpressfläche 11 die Stirnfläche 19b erreicht hat, schnappt die Rastnase 18 nach oben und verriegelt sich mit der Rastfläche 8. Damit ist eine sichere Verclipsung beider Klemmelemente 1, 10 gegeben, die sich von selbst nicht wieder löst, allerdings von außen, z. B. mittels eines Schraubendrehers wieder demontiert werden kann.The assembly of the two clamping elements 1, 10 is very simple: first is the first clamping element 1 with its contact surface 2 to a first End face 19 a applied, wherein the holding pockets 6 and the stop strips 5 rest on the side part 21. The first clamping element 1 is then against pressed the end face 19 a, so that the holding element 3, 4 in the dig in ribs not shown. Thereafter, the second clamping element 10 placed in a corresponding, opposite position and pressed with its contact surface 11 against the end face 19b, wherein the Latch 18 is already inserted into the opening 6a of the holding pocket 6. During the pressing movement, the locking lug 18 slides on the ramp 7 and springs down (seen in the drawing) down. At the end of the pressing movement, d. H. when the contact surface 11 reaches the end face 19b has, snaps the locking lug 18 upwards and locks with the Locking surface 8. This is a secure Verclipsung both clamping elements 1, 10 given, which does not solve itself, but from the outside, z. B. can be dismantled by means of a screwdriver.

Die beiden o. g. Klemmelemente 1, 10 können auch aus Metall, z. B. durch Spritzguss hergestellt werden.The two o. G. Clamping elements 1, 10 may also be made of metal, for. B. by Injection molding are produced.
