Description

Stand der TechnikState of the art

Die Erfindung betrifft einen Wärmetauscher mit mindestens einem Anschlußelement nach der Gattung des Patentanspruches 1. Außerdem betrifft die Erfindung ein Verfahren zur Herstellung der Verbindung zwischen Wärmetauscher und Anschlußelement.The invention relates to a heat exchanger with at least one connection element according to the preamble of claim 1. The invention also relates to a Process for the connection between heat exchanger and Connecting element.

Ein Wärmetauscher in Stapelbauweise ist z. B. aus der DE 93 09 741 bekannt. Dieser Wärmetauscher besteht aus ineinander gestellten wannenförmigen Stapelscheiben sowie Abschlußplatten. Die Bauelemente sind miteinander verlötet und ergeben auf diese Weise ein nach außen hin dichtes System. Ein- und Auslässe sind für den Kühlmittelkreislauf sowie für den Kreislauf des zu kühlenden Fluids vorgesehen.A stacked heat exchanger is e.g. B. from DE 93 09 741 known. This heat exchanger consists of trough-shaped, nested Stacking washers and end plates. The components are soldered together and in this way result in a dense system towards the outside. Inlets and outlets are for the coolant circuit and for the circuit of the fluid to be cooled intended.

Zur Befestigung des Wärmetauschers ist mindestens eine der Abschlußplatten als Flansch ausgebildet. Dieser kann mit Bohrungen versehen werden und z. B. mit Hilfe von Schrauben am vorgesehenen Montageort befestigt werden. Nachteilig an dieser Lösung ist jedoch der zusätzlich anfallende Arbeitsgang zum Vorsehen der Bohrung in den Abschlußplatten. Am Montageort muß gleichfalls eine Bohrung, evtl. mit einem Gewinde versehen, vorgesehen werden. Auch die als Befestigungsmittel verwendeten Schrauben bedeuten einen zusätzlichen Aufwand an Komponenten.To attach the heat exchanger is at least one of the end plates as Flange formed. This can be provided with holes and z. B. with help be fastened by screws at the intended installation location. Disadvantage of this The solution, however, is the additional process of providing the hole in the end plates. There must also be a hole at the installation location, possibly with provided with a thread. Even as a fastener The screws used mean an additional outlay on components.

Die Herstellung der Wärmetauscher erfolgt üblicherweise in einem Ofen. Die mit einem Lotwerkstoff beschichteten Bauteile des Wärmetauschers werden lose vormontiert und provisorisch fixiert. Im Ofen herrscht eine Temperatur, in dem der Lotwerkstoff schmilzt und in die Verbindungsstellen der einzelnen Bauteile fließt. Auf diese Weise werden die Bauteile miteinander verbunden und die Flüssigkeitskreisläufe gegeneinander sowie gegen die Umgebung hin abgedichtet. The heat exchangers are usually manufactured in an oven. With Components of the heat exchanger coated with a solder material become loose pre-assembled and provisionally fixed. There is a temperature in the oven at which the Solder material melts and flows into the connection points of the individual components. On in this way the components are connected and the Liquid circuits sealed against each other and against the environment.

Aus der EP-A-0 597 778 ist ein Wärmetauscher bekannt, bei dem Haltevorrichtungen für etwaige Anschlußelemente vollständig als Teil einer Abschlußplatte ausgebildet sind. Die Abschlußplatte muß mit den Anschlußelementen zusätzlich durch Kleben, Verschweißen, Verschrauben oder ähnlichem verbunden sein. Dies erfordert einen zusätzlichen Arbeitsvorgang.From EP-A-0 597 778 a heat exchanger is known in which holding devices fully formed as part of an end plate for any connection elements are. The end plate must also be glued to the connection elements, Welding, screwing or the like. This requires one additional operation.

Die WO 86/05866 beschreibt ebenfalls einen Wärmetauscher, wobei die Verbindung zwischen Anschluß und Wärmetauscher durch eine Verformung hergestellt werden muß. WO 86/05866 also describes a heat exchanger, the connection between connection and heat exchanger are produced by deformation got to.

Die Aufgabe der Erfindung besteht darin eine Kombination aus Wärmetauscher bzw. dessen Anschlußelementen zu schaffen, die hinsichtlich des Fertigungsaufwandes des Montageaufwandes bzw. der Funktionszuverlässigkeit optimiert ist.The object of the invention is a combination of heat exchanger or to create its connecting elements, the manufacturing costs the assembly effort or the functional reliability is optimized.

Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Ferner wird gemäß dem Anspruch 3 ein Verfahren zur Herstellung der Verbindung zwischen dem Wärmetauscher und seinen Anschlußelementen beansprucht.This object is solved by the features of claim 1. Further is a method for producing the compound according to claim 3 between the heat exchanger and its connection elements claimed.

Vorteile der ErfindungAdvantages of the invention

Die erfindungsgemäße Kombination aus Wärmetauscher und Anschlußelement weist einen Verbindungsmechanismus auf, der aus Haltevorrichtungen am Wärmetauscher besteht, die mit Aufnahmen an den Anschlußelementen zusammenwirken. Zusätzliche Verbindungsmittel wie z. B. Schrauben sind nicht notwendig. Die Haltevorrichtung sind als Teil des Gehäuses ausgebildet.The combination of heat exchanger and connection element according to the invention has a link mechanism that consists of holding devices on There is a heat exchanger with receptacles on the connection elements interact. Additional connecting means such. B. screws are not necessary. The holding device are designed as part of the housing.

Haltevorrichtung und Aufnahmen weisen eine einfache Geometrie auf. Die Aufnahmen können daher bereits im Urformwerkzeug der Anschlußelemente vorgesehen werden. Dadurch fallen zusätzliche Arbeitsgänge z. B. für das vorsehen von Bohrungen, die nicht hinterschneidungsfrei im Urformwerkzeug vorgesehen werden können, weg.The holding device and the receptacles have a simple geometry. The Recordings can therefore already in the master tool of the connection elements be provided. This eliminates additional operations such. B. provide for that of holes that are not provided in the master tool without undercuts can be gone.

Eine zweckmäßige Ausbildung des Erfindungsgedankens sieht vor, die Haltevorrichtung durch Verformung bestimmter Teile des Wärmetauschers, insbesondere der Abschlußplatten, zu erzeugen. Die Abschlußplatten sind im allgemeinen Stanzteile und werden zu deren Versteifung häufig mit Sicken versehen. In diesen Verfahrensschritten können ohne zusätzlichen Fertigungsaufwand auch Haltevorrichtung an die Abschlußplatte angeformt werden. Durch das Vorsehen derartiger Haltevorrichtungen entsteht also fast kein Mehraufwand. Appropriate training of the inventive concept provides that Holding device by deformation of certain parts of the heat exchanger, especially the end plates. The end plates are in general stamped parts and are often provided with beads to stiffen them. These process steps can also be carried out without additional manufacturing effort Holding device are integrally formed on the end plate. By providing Holding devices of this type therefore generate almost no additional effort.

Eine andere nicht beanspruchte Variante der Haltevorrichtung besteht aus Profilleisten, die fest mit dem Gehäuse verlötet sind. Die Profilleisten lassen sich aus kostengünstig zu beschaffenden Halbzeugen herstellen. Sie können mit unwesentlichem Mehraufwand in das lose vormontierte Stapelscheibenpaket des Wärmetauschers integriert werden. Durch die Behandlung im Ofen entsteht zwischen den Profilleisten und dem Gehäuse eine feste Verbindung. Die Behandlung des Wärmetauschers im Ofen ist ein Herstellungsschritt der sich aufgrund des Stapelscheibenaufbaus des Wärmetauschers ergibt. Somit ist auch bei dieser Variante kein zusätzlicher Verfahrensschritt zur Fixierung der Haltevorrichtung am Wärmetauscher notwendig.Another variant of the holding device which is not claimed consists of profiled strips which are fixed to the Housing are soldered. The profile strips can be inexpensively Manufacture semi-finished products. You can with insignificant Additional effort in the loosely preassembled stacked plate package of the heat exchanger to get integrated. The treatment in the oven creates between the profile strips and the housing a firm connection. Treatment of the heat exchanger in the Oven is a manufacturing step that is due to the stacked disc structure of the Heat exchanger results. So there is no additional one in this variant Process step for fixing the holding device to the heat exchanger necessary.

Es ist vorteilhaft, Arretierungen in der Verbindung zwischen den Haltevorrichtungen am Gehäuse und den Aufnahmen an den Anschlußelementen vorzusehen. Diese haben den Zweck, ein ungewolltes Lösen der Verbindung zu verhindern. Wenn die Anschlußelemente aus Kunststoff sind, kann die Eigenelastizität dieses Werkstoffes benutzt werden, z. B. durch Vorsehen von elastischen Schnappnasen. Ein Vorsehen von Arretierung hat den Vorteil, daß die Verbindung zwischen Anschlußelementen und Wärmetauscher lösbar ausgeführt sein kann.It is advantageous to have detents in the connection between the holding devices to be provided on the housing and the receptacles on the connection elements. This have the purpose of preventing an unwanted loosening of the connection. If the Connection elements are made of plastic, the inherent elasticity of this material be used, e.g. B. by providing elastic snap noses. A provision of locking has the advantage that the connection between connection elements and heat exchanger can be made detachable.

Natürlich müssen die Haltevorrichtung am Wärmetauscher sowie die Aufnahmen an den Anschlußelementen miteinander korrespondieren. Hierzu ist insbesondere auch eine entsprechende geometrische Ausgestaltung der Anschlußelemente notwendig. Dies kann erfindungsgemäß z. B. dadurch gelöst werden, daß Nuten oder Flansche am Anschlußeiement vorgesehen werden, die mit den Haltevorrichtungen am Wärmetauscher im Eingriff stehen. Handelt es sich bei dem Anschlußelementen z. B. um Ölfilter mit im wesentlichen zentralsymetrischer Geometrie, lassen sich diese Nuten bzw. Flansche durch eine durch die Symetrieachse verlaufende Formteilung hinterschneidungsfrei herstellen.Of course, the holding device on the heat exchanger as well as the receptacles the connection elements correspond with each other. This is particularly important a corresponding geometric design of the connection elements is necessary. This can, according to the invention, for. B. can be solved in that grooves or flanges be provided on the connecting element, which with the holding devices on Heat exchangers are engaged. Is it the connecting elements z. B. around oil filters with essentially symmetrical geometry, they can Grooves or flanges through a shape division running through the axis of symmetry Manufacture without undercuts.

Für die Herstellung des Wärmetauschers ist ein Verfahren gemäß Anspruch 3 geeignet. Danach wird das Anschlußelement an den vorgesehenen Montageort am Wärmetauscher gebracht. Anschließend werden die Haltevorrichtungen plastisch verformt, z. B. durch Umbiegen. Hierdurch entsteht ein Formschluß zwischen Anschlußelement und Wärmetauscher. Das Anschlußelement bleibt dabei weitgehend unverformt.For the manufacture of the heat exchanger is a process according to Claim 3 suitable. Then the connector is provided on the Installation site brought to the heat exchanger. Then the Holding devices plastically deformed, e.g. B. by bending. This creates a Positive connection between the connection element and the heat exchanger. The connector remains largely undeformed.

Die beschriebene Verbindung zwischen Wärmetauscher und Anschlußelement ist nicht lösbar, es sei denn, man bringt die Haltevorrichtung in ihre ursprüngliche Form zurück. Jedoch ist das Montageverfahren durch Verformung der Halteelemente besonders bei großen Stückzahlen sehr wirtschaftlich. Die Montage kann maschinell in einer dafür vorgesehenen Vorrichtung erfolgen.The described connection between the heat exchanger and the connecting element is cannot be removed unless the holding device is brought into its original shape back. However, the assembly process is due to deformation of the holding elements very economical, especially for large quantities. The assembly can be done mechanically take place in a device provided for this purpose.

Der Schenkel 26 der Profilleiste 24 ist nur in den dargestellten Bereichen A ausgeschnitten. Zwischen diesen Bereichen bleibt die Profilleiste 24 unverformt. Die unverformten Bereiche der Profilieiste 24 sind zusätzlich nötig, damit diese nicht in mehrere Einzelteile zerfällt. In Figure 4, the engagement of the plastically deformed cut parts 27 in recognize the groove 28. The leg 26 of the profile bar 24 is only shown in the Areas cut out. Profile strip 24 remains between these areas undeformed. The undeformed areas of the profiled strip 24 are additionally necessary for this it does not break down into several individual parts.

In Figur 5 ist eine Version der Haltevorrichtungen 19 dargestellt, die als Bajonettverschluß ausgebildet ist. Die Haltevorrichtungen sind, ähnlich wie in Figur 2 dargestellt, aus der Abschlußplatte 18 und der Profilleiste 24 gebildet. Der Filter 12 besitzt einen flanschartigen Ansatz der die Funktion der Aufnahmen 19 übernimmt. Damit der Ölfilter zwischen den Haltevorrichtungen plaziert werden kann, besitzt der flanschartige Ansatz Aussparungen 29. Der Ölfilter kann in eine hierfür vorgesehene Führung 30 eingesetzt werden. Durch anschließende Drehung des Ölfilters 12 um 90° kommen die Aufnahmen 19 unter den Haltevorrichtungen 17 zum Eingriff. Dabei rastet eine Arretierung 31 ein, die durch korrespondierende Einbuchtungen 32 in der Haltevorrichtung bzw. im Ölfilter gebildet wird.In Figure 5, a version of the holding devices 19 is shown, which as Bayonet lock is formed. The holding devices are, similar to that in FIG. 2 shown, formed from the end plate 18 and the profile strip 24. The filter 12 has a flange-like approach that takes over the function of the receptacles 19. So that the oil filter can be placed between the holding devices, the flange-like approach recesses 29. The oil filter can be in a designated Guide 30 are used. By subsequent rotation of the oil filter 12 The receptacles 19 come into engagement at 90 ° under the holding devices 17. there engages a lock 31, which by corresponding indentations 32 in the Holding device or in the oil filter is formed.

Figur 6 zeigt eine weitere alternative nicht beanspruchte Ausgestaltung für die Haltevorrichtung. Diese besteht aus einer Buchse 33, die z. B. in den Einlaß 15 eingelötet ist. Der Ölfilter 12 wird mit seiner innenöffnung 34 auf die Buchse geschoben, wobei diese durch plastische Verformung den Ölfilter festklemmt. Die Kanten 23 vor der montagebedingeten Verformung der Buchse 33 sind in Figur 6 gestrichelt dargestellt.FIG. 6 shows a further alternative embodiment for the holding device which is not claimed. This exists from a socket 33, the z. B. is soldered into the inlet 15. The oil filter 12 is with its inner opening 34 pushed onto the socket, this by plastic Deformation clamps the oil filter. The edges 23 before the assembly Deformation of the socket 33 is shown in dashed lines in FIG. 6.
