Description

Die Erfindung betrifft einen Kühler, insbesondere für Kraftfahrzeuge, mit einer von einem zu kühlenden Medium durchströmten Rohr, das zur Anordnung in einem Kühlluftstrom bestimmt ist.The invention relates to a cooler, in particular for Motor vehicles with one of a medium to be cooled flowed through pipe that is to be arranged in a cooling air flow is determined.

Zur Schmiermittelkühlung und zur Kühlung von Hydraulikflüssigkeiten werden in Kraftfahrzeugen häufig Kühler verwendet, die aus in einem Kühlluftstrom angeordneten Rohrschleifen bestehen. Diese Rohrschleifen können aus einem glatten Rundrohr oder zur Erhöhung der Kühlleistung bei gegebener Länge aus Rippenrohr bestehen, wobei das Rippenrohr unter Verwendung eines glatten Rundrohrs hergestellt ist, auf dem radial abstehende, dünnwandige Rippen angebracht oder ausgeformt sind, die das Rohr als einzelne Ringe oder in Form einer Wendel umgeben. Die Herstellung derartiger Rippenrohre und das Biegen der Rippenrohre in die für den jeweiligen Kühler geeignete Schleifenform ist aufwendig.For cooling lubricants and cooling hydraulic fluids coolers are often used in motor vehicles, which consist of pipe loops arranged in a cooling air flow consist. These pipe loops can be made from one smooth round tube or to increase the cooling capacity given length consist of finned tube, the finned tube made using a smooth round tube is attached to the radially projecting, thin-walled ribs or are molded to form the tube as an individual Rings or in the form of a spiral. The production such finned tubes and the bending of the finned tubes in is the appropriate loop shape for the respective cooler consuming.

Der Erfindung liegt die Aufgabe zugrunde, einen Kühler der eingangs genannten Art zu schaffen, der kostengünstiger herstellbar ist als ein unter Verwendung von Rippenrohren hergestellter Kühler, wobei die auf eine Rohrlängeneinheit bezogene Kühlleistung erheblich höher ist als die Kühlleistung glatter Rohre vergleichbarer Abmessung.The invention has for its object a cooler to create the kind mentioned above, the more cost-effective can be manufactured as one using finned tubes manufactured cooler, which on a pipe length unit related cooling capacity is significantly higher than the cooling capacity smooth pipes of comparable dimensions.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß das Rohr des Kühlers eine Vielzahl angestauchter, ringförmiger Wellen aufweist, die sich von der Rohrwand radial nach außen erstrecken und einen Abstand voneinander haben. Die einzelnen Wellen sind hierbei vorzugsweise so gestaltet, daß zwischen ihren sich radial erstreckenden Wandabschnitten ein mit dem Innenraum des Rohrs in Verbindung stehender Zwischenraum vorgesehen ist. Als besonders zweckmäßig hat sich eine Breite des Zwischenraums erwiesen, die kleiner oder gleich der Wandstärke des Rohrs bzw. der Wandabschnitte der Wellen ist.According to the invention this object is achieved in that the Tube of the cooler a variety of upset, annular Has waves extending radially from the pipe wall extend outside and have a distance from each other. The individual waves are preferably designed so that between their radially extending wall sections one related to the interior of the pipe Space is provided. Has been particularly useful the width of the gap turned out to be smaller or equal to the wall thickness of the pipe or the wall sections the waves is.

Die erfindungsgemäße Gestaltung des Kühlers zeichnet sich durch niedrige Herstellkosten und gute Kühlleistung aus. Die angestauchten Wellen bewirken eine Oberflächenvergrößerung von bis zu 50% im Vergleich zu einem geraden Rohr. Zudem wird durch die beim Stauchen der Wellen erzeugte Innenkontur des Rohres eine Verwirbelung des durch das Rohr geleiteten Mediums erreicht, woraus ein besserer Wärmeübergang und eine höhere Kühlleistung resultiert. Als vorteilhaft ist weiterhin anzusehen, daß die Wellen auf dem Rohr in beliebiger Position angeordnet sein können. Dadurch ist eine flexible Anpassung an die Einbaugegebenheiten für den Kühler leicht möglich. Neben den mit Wellen versehenen Wellrohrabschnitten können auch glatte Rohrabschnitte vorgesehen sein, die anschließend umgeformt oder mit Haltern versehen werden können. Zur Herstellung des erfindungsgemäßen Kühlers können Rohre aus Aluminium verwendet werden.The design of the cooler according to the invention stands out due to low manufacturing costs and good cooling performance. The upset waves cause an increase in surface area of up to 50% compared to a straight pipe. In addition, the generated when compressing the waves Inner contour of the tube is swirling through the tube conducted medium achieved, resulting in a better heat transfer and a higher cooling capacity results. As beneficial it can also be seen that the waves on the tube can be arranged in any position. This is a flexible adaptation to the installation conditions for the Cooler easily possible. In addition to those with waves Corrugated pipe sections can also provide smooth pipe sections be subsequently formed or with holders can be provided. To produce the invention Aluminum tubes can be used for the cooler.

Erfindungsgemäß wurde weiterhin gefunden, daß als Ausgangshalbzeug zur Herstellung des Kühlers auch ein glattes, mit einem Kunststoff, insbesondere Polyamid, beschichtetes Rohr aus Aluminium verwendet werden kann, da sich gezeigt hat, daß bei dem Stauchvorgang zur Herstellung der Wellen die Kunststoffbeschichtung nicht beschädigt wird. Die Verwendung eines vorbeschichteten Rohrs führt zu einer erheblichen Fertigungsvereinfachung, da eine nachträgliche Beschichtung des gewellten Rohrs sehr viel aufwendiger ist. According to the invention it was also found that as a starting semifinished product to produce the cooler also a smooth, with a plastic, especially polyamide, coated tube aluminum can be used because it has been shown that in the upsetting process to produce the shafts Plastic coating is not damaged. The usage of a pre-coated pipe leads to a significant one Simplification of production, as a subsequent Coating the corrugated tube is much more complex.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels näher erläutert, das in der Zeichnung dargestellt ist.The invention is described below using an exemplary embodiment explained in more detail, which is shown in the drawing is.

Die Zeichnung zeigt einen Abschnitt eines Rohres 1 eines erfindungsgemäßen Kühlers, teilweise geschnitten. Das Rohr 1 weist in regelmäßigem Abstand ringförmige Wellen 2 auf, die sich radial nach außen erstrecken und durch axiales Stauchen eines zuvor glatten, zylindrischen Rohrs als Ausgangshalbzeug erzeugt worden sind. Zwischen den Wellen 2 befinden sich glatte zylindrische Rohrabschnitte 3, deren Durchmesser im wesentlichen dem des Ausgangshalbzeugs entspricht. Die einzelnen Wellen 2 haben ebene, zueinander parallele Wandabschnitte 4 in Form von Kreisringscheiben, die radial zur Rohrachse angeordnet sind und die an ihren Rändern in Wandabschnitte 5, 6 übergehen, die etwa die Form von Torusteilflächen haben. Zwischen den Wandabschnitten 4 und 6 jeder Welle 2 ist ein ringförmiger Zwischenraum 7 vorgesehen, der mit dem Innenraum 8 des Rohrs 1 in Verbindung steht.The drawing shows a section of a tube 1 cooler according to the invention, partially cut. The pipe 1 has annular shafts 2 at regular intervals, which extend radially outwards and through axial Compression of a previously smooth, cylindrical tube as a semi-finished product have been generated. Between the waves 2 there are smooth cylindrical tube sections 3, the Diameter essentially corresponds to that of the starting semi-finished product. The individual shafts 2 have one another parallel wall sections 4 in the form of circular washers, which are arranged radially to the pipe axis and which on their Edges merge into wall sections 5, 6, which have approximately the shape of partial torus surfaces. Between the wall sections 4 and 6 of each shaft 2 is an annular space 7 provided that in connection with the interior 8 of the tube 1 stands.

Die Wellen 2 haben einen Außendurchmesser, der etwa das 1,3- bis 1,5-fache des Außendurchmessers der Rohrabschnitte 3 beträgt. Die Breite des Zwischenraums 7 ist im wesentlichen gleich der Wandstärke der Rohrabschnitte 3, kann aber auch kleiner bemessen sein. Insbesondere im radial äußeren Bereich ist eine kleinere Breite oder unzureichende Ausprägung des Zwischenraums 7 ohne Nachteil für die Funktion. Der Mittenabstand zwischen den einzelnen Wellen kann beliebig gewählt werden. Als besonders günstig hat sich ein Mittenabstand erwiesen, der etwa dem Außendurchmesser der Rohrabschnitte 3 entspricht.The shafts 2 have an outer diameter which is approximately that 1.3 to 1.5 times the outside diameter of the pipe sections 3 is. The width of the gap 7 is essentially equal to the wall thickness of the pipe sections 3, but can also be smaller. Especially in the radially outer Area is a smaller width or insufficient specification of the space 7 without disadvantage for the function. The center distance between the individual shafts can be any to get voted. A center distance has proven to be particularly favorable proven to be about the outside diameter of the Pipe sections 3 corresponds.

Bei einem aus dem Rohr 1 hergestellten Kühler wird das Rohr 1 von einem zu kühlenden flüssigen Medium, z.B. dem Öl eines Verbrennungsmotors oder eines Kraftfahrzeuggetriebes durchströmt und auf seiner Außenseite mit einem Kühlluftstrom beaufschlagt. Hierbei sorgt zum einen die durch die Ausbildung der Wellen 2 um bis zu 50% vergrößerte Oberfläche des Rohrs 1 für einen im Vergleich zu einem glatten Rohr größeren Wärmeübergang. Zum Zweiten bewirkt die durch die Wellen 2 gebildete, sich periodisch ändernde Innenkontur des Rohrs 1 Turbulenzen in dem zu kühlenden Medium und sorgt dadurch für einen erheblich verbesserten Wärmeübergang zwischen diesem Medium und der Rohrwand. Insgesamt wird auf diese Weise eine deutlich erhöhte Kühlerleistung erreicht, die an die Kühlleistung der aufwendigeren Rippenrohre nahezu heranreicht.In a cooler made from tube 1, the tube 1 from a liquid medium to be cooled, e.g. the oil an internal combustion engine or a motor vehicle transmission flows through and on the outside with a cooling air flow applied. On the one hand, this is ensured by Formation of waves 2 by up to 50% enlarged surface of tube 1 for one compared to a smooth one Pipe greater heat transfer. Second, it causes through the waves 2 formed, periodically changing inner contour of the pipe 1 turbulence in the medium to be cooled and thereby ensures a significantly improved heat transfer between this medium and the pipe wall. All in all becomes a significantly increased cooler performance in this way achieved that the cooling performance of the more complex finned tubes almost approached.
