Description

Die Erfindung betrifft einen Wärmetauscher, insbesondere einen Ölkühler, mit den Merkmalen aus dem Oberbegriff des Anspruchs 1.The invention relates to a heat exchanger, in particular an oil cooler, with the features of the preamble of claim 1.

Ein Ölkühler ist aus DE 103 47 181 A1 bekannt. Am dort gezeigten Ölkühler werden die Dichtungen durch daran angeformte Nasen in die Dichtungsaufnahme der zweigeteilten Befestigungsplatte eingepresst. Solche Dichtungen sind Spezialanfertigungen und deshalb teuer.An oil cooler is out DE 103 47 181 A1 known. At the oil cooler shown there, the seals are pressed by noses formed thereon into the seal receptacle of the two-part mounting plate. Such seals are custom-made and therefore expensive.

Die Aufgabe der vorliegenden Erfindung ist es, den Wärmetauscher in seiner Handhabung bei der Montage an einem Gehäuse weiter zu verbessern und den Einsatz gewöhnlicher O-Ring-Dichtungen zu gestatten.The object of the present invention is to further improve the handling of the heat exchanger during assembly to a housing and to allow the use of ordinary O-ring seals.

EP 0 801 283 A1 zeigt eine Lösung, wo die Endplatte massiv ist, und mit einer Nut vorgesehen für die Einführung der O-Ring Dichtung. EP 0 801 283 A1 shows a solution where the end plate is solid, and provided with a groove for the insertion of the O-ring seal.

Die Aufgabe wird aber erfindungsgemäß anders gelöst durch die kennzeichnenden Merkmale des Anspruchs 1.
Es ist vorgesehen, dass durch die Formgebung der Ränder, die sich um die Öffnungen der mindestens zwei Befestigungsplatten erstrecken, die Dichtungen an ihrem Platz fixiert sind. Dadurch wird bewirkt, dass als Dichtung ein einfacher O - Ring verwendet werden kann, der an Ort und Stelle liegen bleibt, wodurch die Montage des Ölkühlers vereinfacht wird.The object is achieved differently according to the invention by the characterizing features of claim 1.
It is envisaged that the seals are fixed in place by the shaping of the edges, which extend around the openings of the at least two mounting plates. This has the effect that a simple O - ring can be used as the seal, which remains in place, thus simplifying the assembly of the oil cooler.

Ein weiterbildender Aspekt sieht vor, dass die Formgebung des Randes der Öffnungen der einen Befestigungsplatte mit Vorsprüngen ausgebildet ist. Beispielsweise kann eine wellenförmige Kontur mit Wellenbergen und Wellentälern vorgesehen sein. Die Formgebung des Randes der Öffnung der anderen Befestigungsplatte weist eine kragenartige Kontur auf, die in die Öffnung der einen Befestigungsplatte eingreift. Deshalb wird zwischen den beiden Rändern der Öffnungen eine Rinne ausgebildet, in der die Dichtung eingeklemmt ist.A further development aspect provides that the shaping of the edge of the openings of the one fastening plate is formed with projections. For example, a wave-shaped contour can be provided with wave crests and troughs. The shape of the edge of the opening of the other mounting plate has a collar-like contour which engages in the opening of a mounting plate. Therefore, a groove is formed between the two edges of the openings, in which the seal is clamped.

Beschreibung der Erfindung an Hand der Fig. 1 bis 3:

  • Die Fig. 1 zeigt einen Schnitt durch den gesamten Wärmetauscher.
  • Die Fig.2 zeigt eine Detailansicht des Ölkühlers von unten.
  • Die Fig. 3 zeigt einen vergrößerten Ausschnitt aus der Fig. 1.
Description of the invention with reference to the Fig. 1 to 3 :
  • The Fig. 1 shows a section through the entire heat exchanger.
  • The Fig.2 shows a detailed view of the oil cooler from below.
  • The Fig. 3 shows an enlarged section of the Fig. 1 ,

In der Fig. 1 ist ein Schnitt des Ölkühlers 1 zu sehen. Der Ölkühler 1 selber ist nicht im Detail gezeigt. Er ist aus ineinander gestapelten wannenförmigen Wärmetauscherplatten aufgebaut. Zwischen den Wärmetauscherplatten sind abwechselnd Strömungskanäle für Öl und Kühlflüssigkeit vorhanden. Über die Zu-und Abführkanäle werden die Medien den Strömungskanälen zugeführt bzw. daraus abgeführt. An dem unteren Ende des Ölkühlers 1 befinden sich Befestigungsplatten 2 und 3. Dargestellt ist eine zweigeteilte Befestigungsplatte 2, 3, mit der der Ölkühler an einem Gehäuse, zum Beispiel an einem Motorblock, befestigt wird. Je nach Anforderung kann die Befestigungsplatte auch aus mehr als zwei Teilen bestehen. (siehe Ausschnitt A in Fig. 3, wo eine Linie andeuten soll, dass beispielsweise die Befestigungsplatte 3 aus mehreren Platten bestehen kann). Die einzelnen Befestigungsplatten können die gleiche Dicke aufweisen oder unterschiedlich dick ausgestaltet sein. Um die Qualität der Verbindung zwischen dem Ölkühler 1 und der direkt daran anschließenden Befestigungsplatte 2 zu verbessern, sind in der Befestigungsplatte 2 Ausschnitte 30 vorgesehen, die dazu dienen, überschüssiges Lot aufzunehmen und Lufteinschlüsse in der Lötverbindung zu vermeiden.
In den Befestigungsplatten 2, 3 befinden sich mehrere Öffnungen 21 durch die ein Medium, zum Beispiel das Öl, in den Kühler eintritt oder daraus austritt. An der Oberseite des Ölkühlers 1 können sich, wie in der Fig. 1 gezeigt, Anschlussstutzen 5 für das andere Medium befinden. Je nach Bedarf kann das zweite Medium aber auch durch die Befestigungsplatten 2, 3 hindurch zu - und abgeführt werden. In dem Fall gibt es mindestens vier Öffnungen 21 mit je einer Dichtung 20. Die Dichtung 20 ist ein üblicher für solche Zwecke eingesetzter O-Ring mit einem gleichmäßigen Durchmesser d. In the Fig. 1 is a section of the oil cooler 1 can be seen. The oil cooler 1 itself is not shown in detail. It is constructed of stacked trough-shaped heat exchanger plates. There are alternating flow channels for oil and coolant between the heat exchanger plates. About the inlet and outlet channels, the media are supplied to the flow channels and discharged therefrom. At the lower end of the oil cooler 1 are mounting plates 2 and 3. Shown is a two-part mounting plate 2, 3, with which the oil cooler is attached to a housing, for example on an engine block. Depending on requirements, the mounting plate can also consist of more than two parts. (see section A in Fig. 3 where a line indicates that, for example, the mounting plate 3 may consist of several plates). The individual mounting plates may have the same thickness or be configured differently thick. In order to improve the quality of the connection between the oil cooler 1 and the directly adjoining mounting plate 2 , 2 cutouts 30 are provided in the mounting plate, which serve to absorb excess solder and to avoid air pockets in the solder joint.
In the mounting plates 2, 3 there are a plurality of openings 21 through which a medium, for example the oil, enters or exits the cooler. At the top of the oil cooler 1 can, as in the Fig. 1 shown, connecting pieces 5 are for the other medium. Depending on requirements, however, the second medium can also be fed in and out through the attachment plates 2, 3 . In that case, there are at least four openings 21 , each with a seal 20. The seal 20 is a common O-ring used for such purposes with a uniform diameter d.

Die Fig. 3 zeigt im Detail den Ausschnitt aus der Fig. 1, in dem die Öffnung 21 zu sehen ist. Die Fixierung der Dichtung 20 um die Öffnung 21 wird durch die Formgebung des umgebogenen Randes 22 der Öffnung 21a der Befestigungsplatte 2 und der wellenförmigen Ausgestaltung des Randes 25 der Öffnung 21b der Befestigungsplatte 3 erreicht.
Aus den Befestigungsplatten 2, 3 werden bei deren Herstellung jeweils die Öffnungen 21a und 21b ausgestanzt. Die Öffnung 21a in der Befestigungsplatte 2 ist kleiner als die Öffnung 21b in der Befestigungsplatte 3, da nach oder gleichzeitig mit dem Ausstanzen der Rand 22 der Öffnung 21a nach unten gebogen wird, um die Dichtung 20 zu fixieren. Der Rand 22 weist eine kragenartige Kontur auf, wobei idealerweise der Rand 22 um etwa 90° gegenüber der Ebene der Befestigungsplatte 2 umgebogen ist. Das obere Ende des Kragens weist einen Biegeradius auf, so dass dieser Bereich trichterförmig ausgebildet ist. Am unteren Ende ist der umgebogene Rand 22 rundum gerade. Er könnte jedoch auch einen wellenartigen Verlauf aufweisen. Der Rand 22 wird dabei soweit nach unten gebogen, dass die Dichtung 20 gut gehalten wird. Der Rand sollte nicht über die Befestigungsplatte 3 überstehen. Wäre dass der Fall, so könnte die Dichtung 20 nicht mehr zwischen Ölkühler 1 und Gehäuse eingeklemmt werden und der Ölkühler 1 wäre nicht mehr dicht mit dem Gehäuse verbunden.
Der umgebogene Rand 22 der Öffnung 21a greift in die Öffnung 21b hinein. Die Öffnung 21b in der Befestigungsplatte 3 muss größer sein, da sonst die Dichtung 20 zwischen dem Rand 22 und dem wellenförmigen Rand 25 der Öffnung 21b in der Nut 28 keinen Platz hat. Der wellenförmige Rand 25 der Öffnung 21b besitzt mehrere Wellenberge 26 und Wellentäler 27. Mit den Wellenbergen 26 wird die Dichtung 20 an den umgebogenen Rand 22 der Öffnung 21a festgedrückt. (siehe Fig. 2) In diesem Bereich ist in der Nut 28 lokal der Durchmesser D zwischen den beiden Rändern 22 und 25 der Öffnungen 21a und 21b der beiden Befestigungsplatten 2 und 3 kleiner als der Durchmesser d der Dichtung 20. Die Wellentäler 27 dienen dazu, nach dem Befestigen des Ölkühlers 1 an dem Gehäuse der Dichtung 20 Platz zu bieten. Dort kann sich also das von den Wellenbergen 26 weg gedrückte Dichtungsmaterial ausbreiten.The Fig. 3 shows in detail the detail from the Fig. 1 in which the opening 21 can be seen. The fixation of the seal 20 around the opening 21 is achieved by the shape of the bent edge 22 of the opening 21a of the mounting plate 2 and the wave-shaped design of the edge 25 of the opening 21b of the mounting plate. 3
The openings 21a and 21b are punched out of the attachment plates 2, 3 during their production. The opening 21 a in the mounting plate 2 is smaller than the opening 21 b in the mounting plate 3, since after or at the same time as the punching, the edge 22 of the opening 21 a is bent down to the Seal 20 to fix. The edge 22 has a collar-like contour, wherein ideally the edge 22 is bent by about 90 ° relative to the plane of the mounting plate 2 . The upper end of the collar has a bending radius, so that this area is funnel-shaped. At the lower end of the bent edge 22 is straight around. However, it could also have a wave-like course. The edge 22 is bent so far down that the seal 20 is held well. The edge should not protrude beyond the mounting plate 3 . If that were the case, the seal 20 could no longer be clamped between the oil cooler 1 and the housing and the oil cooler 1 would no longer be tightly connected to the housing.
The bent edge 22 of the opening 21a engages in the opening 21b . The opening 21b in the mounting plate 3 must be larger, otherwise the seal 20 between the edge 22 and the wavy edge 25 of the opening 21b in the groove 28 has no place. The wave-shaped edge 25 of the opening 21b has a plurality of wave crests 26 and wave troughs 27. The wave crests 26 , the seal 20 is pressed against the bent edge 22 of the opening 21a . (please refer Fig. 2 In this region, in the groove 28, the diameter D between the two edges 22 and 25 of the openings 21a and 21b of the two attachment plates 2 and 3 is smaller than the diameter d of the seal 20. The troughs 27 serve to secure the attachment Oil cooler 1 to the housing of the seal 20 to provide space. There, therefore, the 26 pressed away from the wave crests sealing material can spread.
