Vor dem Lötprozess werden alle Teile positioniert und fixiert, damit sie beim Lötprozess ihre vorbestimmte Lage beibehalten. Für die Fixierung werden in der älteren Anmeldung verschiedene Lösungen vorgeschlagen, u. a. ein Formschluss zwischen den Zusatzteilen und dem Sammelrohr oder Schlitze im Sammelrohr, in welche am Zusatzteil befestigte Fixierelemente eingreifen. Die hierdurch entstehenden Lötspalte zwischen Sammelrohr und Zusatzteilen werden zwar beim Löten, welches nach dem so genannten Nocolok-Verfahren erfolgt, geschlossen; jedoch besteht die Gefahr einer undichten Lötung oder einer Schwachstellenbildung durch ein nicht homogenes Lötnahtgefüge. Da Kondensatoren für Kraftfahrzeuge einer besonders starken Schwingungsbeanspruchung unterliegen, muss die Verbindung insbesondere zwischen Halter und Sammelrohr hinreichend dauerfest und stabil ausgebildet sein.In the aforementioned earlier patent application of the Applicant is a soldered Heat exchanger disclosed, in particular as a capacitor of a Air conditioning system is designed for motor vehicles and at least one refrigerant flange for connection to a refrigerant circuit and holder for Has suspension of the capacitor.

Der Boden 3b weist Durchzüge (querverlaufende Schlitze) 3e auf, in welche die nicht dargestellten Rohrenden der Flachrohre eingesetzt und eingelötet werden. Der Boden 3b wird nach oben durch Oberkanten 3f, 3g begrenzt, die mit dem Deckel 3a auf der Außenseite Absätze bilden. Das gabelförmige Profilstück 12 weist zwei parallel zueinander angeordnete Schenkel 12a, 12b auf, welche das Sammelrohr 3 im Bereich der Überlappungszonen 3c, 3d umfassen. Die Schenkel 12a, 12b sind deutlich über die Überlappungszonen 3c, 3d hinaus verlängert, sodass das Profilstück 12 deutlich mehr als den halben Umfang des Sammelrohres 3 umschließt. Zur Verdeutlichung sind in das Sammelrohr 3 der Mittelpunkt M eines Kreises mit dem Durchmesser des halbschalenförmigen Bodens 3b und vier Kreisquadranten eingezeichnet. Fig. 4 shows the flange 5 (of FIG. 2) in a sectional view (without hatching). The manifold 3 is formed in two pieces, ie, it has a lid part 3a, which is inserted into a bottom part 3b of larger diameter and forms with this lateral overlap zones 3c, 3d, via which lid 3a and bottom 3b are soldered together. The bottom 3b has passages (transverse slots) 3e, in which the pipe ends, not shown, of the flat tubes are inserted and soldered. The bottom 3b is bounded at the top by upper edges 3f, 3g, which form shoulders with the lid 3a on the outside. The fork-shaped profile piece 12 has two legs 12a, 12b arranged parallel to one another, which comprise the collecting tube 3 in the region of the overlapping zones 3c, 3d. The legs 12a, 12b are significantly extended beyond the overlapping zones 3c, 3d, so that the profile piece 12 encloses significantly more than half the circumference of the collecting tube 3. For clarity, the center point M of a circle with the diameter of the half-shell-shaped bottom 3b and four circle quadrants are shown in the manifold 3.

Fig. 5 zeigt eine abgewandelte Ausführungsform eines Flansches 18 mit einem abgewandelten Profilstück 19, welches ebenfalls gabelförmig ausgebildet ist und aus einem Bogenstück 19a sowie zwei daran anschließenden, im Wesentlichen parallel zueinander angeordneten Schenkel 19b, 19c besteht. Auf der Innenseite des Profilstückes 19 sind im Bereich des Überganges des Bogenstückes 19a zu den seitlichen Schenkeln 19b, 19c Absätze 20, 21 angeordnet. In das gabelförmige Profilstück 19 ist ein gestrichelt dargestellter Kreis k mit einem Mittelpunkt M einbeschrieben, wobei der Kreis k etwa dem Umfang des Sammelrohres 3 (vgl. Fig. 4) entspricht. Die Absätze 20, 21 sind also deutlich oberhalb des Mittelpunktes M angeordnet; sie dienen bei der Montage des Profilstückes 19 als Anschlag gegenüber den Oberkanten 3f, 3g des Bodens 3b des Sammelrohres 3 (vgl. Fig. 4). Durch den Mittelpunkt M ist eine in der Zeichnung waagerechte Mittellinie m gelegt, die gegenüber den Absätzen 20, 21 einen Abstand g aufweist. In diesem Bereich g sind die Schenkel 19b, 19c auf der Innenseite gerade und im Wesentlichen parallel zueinander ausgerichtet. Unterhalb der Mittellinie m schließen sich bis zu einem Abstand e konvergierende Bogenstücke an. Die freien Enden der Schenkel 19b, 19c sind als nach innen (in Richtung Mittelpunkt M) weisende Lippen 19d, 19e ausgebildet. Sie umfassen somit das durch den Kreis k dargestellte Sammelrohr mit einem Umfangswinkel α von deutlich mehr als 180°, d. h. etwa 210°. Fig. 5 shows a modified embodiment of a flange 18 with a modified profile piece 19, which is also fork-shaped and consists of a curved piece 19a and two adjoining, substantially parallel legs 19b, 19c. On the inside of the profile piece 19 19a to the lateral legs 19b, 19c paragraphs 20, 21 are arranged in the region of the transition of the elbow piece. In the bifurcated profile piece 19 is a dashed circle k inscribed with a center M, wherein the circle k is approximately equal to the circumference of the collecting tube 3 (see Fig .. 4). The paragraphs 20, 21 are therefore arranged clearly above the center M; they serve during assembly of the profile piece 19 as a stop against the upper edges 3f, 3g of the bottom 3b of the manifold 3 (see Fig. 4). Through the midpoint M is a horizontal center line m is placed in the drawing, which has a distance g with respect to the paragraphs 20, 21. In this area g, the legs 19b, 19c are aligned on the inside straight and substantially parallel to each other. Below the center line m join up to a distance e converging elbows. The free ends of the legs 19b, 19c are formed as inwardly (in the direction of the center M) facing lips 19d, 19e. They thus comprise the collection tube shown by the circle k with a circumferential angle α of significantly more than 180 °, ie about 210 °.

Fig. 6 zeigt den Halter 8 (gemäß Fig. 3) in einer anderen Darstellung, und zwar in einem Querschnitt durch das Sammelrohr 4, welches zweistückig ausgebildet ist. Das Profilstück 15 für den Halter 8 entspricht prinzipiell dem Profilstück 12 für den Flansch 5 (vgl. Fig. 4). Fig. 6 shows the holder 8 (according to FIG. 3) in another illustration, in a cross section through the collecting tube 4, which is formed in two pieces. The profile piece 15 for the holder 8 corresponds in principle to the profile piece 12 for the flange 5 (cf., Fig. 4).

Fig. 7 zeigt den Halter 8 mit Profilstück 15 sowie das zweistückige Sammelrohr 4 vor der Montage. Das Sammelrohr 4 befindet sich dabei in einer nicht dargestellten Vorrichtung, und der Halter 8 wird mit seinem Profilstück 15 derart auf das Sammelrohr 4 aufgesetzt, dass sich anschließend ein Klemm-oder Presssitz ergibt. Um dies zu erreichen, weist das Profilstück 15 eine lichte Weite LW, und das Sammelrohr 4 einen Außendurchmesser DA auf, wobei LW ≤ DA ist. Die Profilgabel 15 hat somit ein Untermass gegenüber dem Außendurchmesser bzw. dieser ein Übermaß gegenüber der Weite der Profilgabel. Vorzugsweise kann die Differenz bzw. das Übermaß DA - LW = 0,1 mm betragen. Zur Montage wird die Profilgabel 15 durch eine nicht dargestellte Vorrichtung gespreizt, d. h. bezüglich des Innenmaßes LW aufgeweitet, bis ein Aufschieben auf das Sammelrohr 4 möglich ist. Nach Erreichen der Endlage (Anschlag) werden die Schenkel der Profilgabel durch die Vorrichtung entlastet und kommen damit unter Vorspannung zur Anlage an den Überlappungsbereichen des Sammelrohres 4. Dabei richtet sich die Vorspannung nach dem gewählten Über- bzw. Untermaß. Die Vorspannung bewegt sich im elastischen Bereich des Werkstoffes des Halters 8, d. h. einer Aluminiumstrangpresslegierung - beim Spreizen der Profilgabel 15 darf also keine plastische Verformung auftreten. Durch den so erzielten Klemmsitz ist der Halter auf dem Sammelrohr 4 für den anschließenden Lötprozess fixiert. Das Lot steht als Lotplattierung zur Verfügung, welche beidseitig auf dem Boden des Sammelrohres 4 und auf der Außenseite des Deckels aufgebracht ist. Das Löten erfolgt nach dem so genannten Nocolok-Verfahren, d. h. vor dem Löten, in diesem Falle auch vor dem Fügen der Teile 8 und 4 wird ein entsprechendes Flussmittel in geeigneter Form aufgebracht. Fig. 7 shows the holder 8 with profile piece 15 and the two-piece manifold 4 before assembly. The manifold 4 is located in a device, not shown, and the holder 8 is placed with its profile piece 15 on the manifold 4 so that then results in a clamping or interference fit. To achieve this, the profile piece 15 has a clear width LW, and the collecting tube 4 has an outer diameter DA, wherein LW ≤ DA. The profile fork 15 thus has an undersize with respect to the outer diameter or this an excess compared to the width of the profile fork. Preferably, the difference or the excess DA - LW = 0.1 mm. For mounting the profile fork 15 is spread by a device, not shown, ie widened with respect to the inner dimension LW until a postponement of the manifold 4 is possible. After reaching the end position (stop), the legs of the profile fork are relieved by the device and thus come under pretension to rest on the overlapping areas of the manifold 4. Here, the bias depends on the selected oversize or undersize. The bias moves in the elastic region of the material of the holder 8, ie an aluminum extruded alloy - when spreading the profile fork 15 so no plastic deformation may occur. By thus achieved clamping fit of the holder is fixed to the manifold 4 for the subsequent soldering process. The solder is available as Lotplattierung available, which is applied on both sides of the bottom of the manifold 4 and on the outside of the lid. The soldering takes place by the so-called Nocolok method, ie before soldering, in this case also before the joining of the parts 8 and 4, a suitable flux is applied in a suitable form.

Fig. 8 zeigt einen Ausschnitt aus Fig. 6, d. h. eine vergrößerte Darstellung des Profilstückes 15 mit Sammelrohr 4 im gefügten Zustand. In dieser Darstellung ist ein Umfangswinkel α in der Größe von 210°, eingeschlossen von Strahlen s1, s2, eingezeichnet, welcher angibt, in welchem Umfangsbereich (Sektor) das Profilstück 15 das Sammelrohr 4 umfasst. Man sieht, dass die Schenkel 15a, 15b über eine durch den Mittelpunkt M verlaufende Durchmesserlinie m verlängert sind, und zwar über die Strahlen s1, s2 des Umfangswinkels α hinaus. Im Bereich der Winkelstrahlen s1, s2 weisen die Schenkel 15a, 15b eine erhöhte Wandstärke w2 gegenüber einer Wandstärke w1 im Bereich der Mittellinie m auf. Die Schenkel 15a, 15b bilden somit unterhalb der Mittellinie m Wulstlippen 15c, 15d aus, welche das Sammelrohr 4 formschlüssig hintergreifen, d. h. ein Lösen des Klemmsitzes verhindem oder zumindest erschweren. Die Montage des gabelförmigen Profilstückes 15 erfolgt in der zu Fig. 7 beschriebenen Weise, d. h. durch maschinelle Aufweitung, anschließendes Fügen und Entlasten der Profilgabel zur Herstellung des Klemmsitzes. Fig. 8 shows a detail of Fig. 6, ie an enlarged view of the profile piece 15 with manifold 4 in the joined state. In this illustration, a circumferential angle α in the size of 210 °, including rays s1, s2, drawn, which indicates in which peripheral region (sector) the profile piece 15 includes the manifold 4. It can be seen that the legs 15a, 15b are extended over a diameter line m extending through the center M, and beyond the rays s1, s2 of the circumferential angle α. In the area of the angle beams s1, s2, the legs 15a, 15b have an increased wall thickness w2 in relation to a wall thickness w1 in the region of the center line m. The legs 15a, 15b thus form below the center line m bulge lips 15c, 15d, which engage behind the collecting tube 4 in a form-fitting manner, ie prevent or at least make it difficult to release the clamping seat. The assembly of the fork-shaped profile piece 15 takes place in the manner described with reference to FIG. 7, ie by machine widening, subsequent joining and unloading of the profile fork for producing the clamping seat.
