Abstract
Gehäuse, insbesondere Gehäuse für einen Motor oder ein Getriebe eines Kraftfahrzeuges, mit mindestens einer Nut (14), welche auf der Außenseite einer Gehäusewand (12) angeordnet ist, wobei eine Abdeckung (16) die mindestens eine Nut (14) derart abschließt, dass die mindestens eine Nut (14) einen flüssigkeitsdichten, länglichen Kanal ausbildet, durch welchen eine Kühlflüssigkeit strömt, dadurch gekennzeichnet, dass die Nut (14) mäanderförmig und labyrinthförmig ausgebildet ist, wobei die Kühlflüssigkeit die von einem erhitzten Medium (10) in die Gehäusewand (12) geleitete Wärme aufnimmt und abführt.Housing, in particular housing for a motor or a gearbox of a motor vehicle, having at least one groove (14) which is arranged on the outside of a housing wall (12), wherein a cover (16) terminates the at least one groove (14) such that the at least one groove (14) forms a liquid-tight, elongate channel through which flows a cooling liquid, characterized in that the groove (14) is meander-shaped and labyrinth-shaped, wherein the cooling liquid from a heated medium (10) into the housing wall ( 12) absorbs conducted heat and dissipates.
Description
Die Erfindung betrifft ein Gehäuse, insbesondere ein Gehäuse für einen Motor oder ein Getriebe eines Kraftfahrzeugs, gemäß dem Oberbegriff von Anspruch 1, sowie ein Verfahren zur Erzeugung von Kühlstrukturen für ein Gehäuse durch Ausbildung mindestens eines länglichen Kanals im Bereich des Gehäuses, wobei der Kanal von einer Kühlflüssigkeit durchströmbar ist, gemäß dem Oberbegriff von Anspruch 4. The invention relates to a housing, in particular a housing for a motor or a transmission of a motor vehicle, according to the preamble of claim 1, and a method for producing cooling structures for a housing by forming at least one elongate channel in the region of the housing, wherein the channel of a cooling liquid can flow through, according to the preamble of claim 4.
Zur Kühlung von Kraftfahrzeugmotoren oder Kraftfahrzeuggetrieben ist es bekannt, Kühlkreisläufe im Bereich des Motors oder des Getriebes anzuordnen. Um eine wirksame Kühlung realisieren zu können, ist es wünschenswert, die von einer Kühlflüssigkeit durchströmbaren Kühlstrukturen, zum Beispiel einen Kühler, möglichst nah am abzukühlenden Medium anzuordnen. Hierzu ist es unter anderem bekannt, schlauch- beziehungsweise rohrartige Kühlstrukturen in das Gehäuse beziehungsweise die Gehäusewand eines Motors oder eines Getriebes zu integrieren. For cooling of motor vehicle engines or motor vehicle transmissions, it is known to arrange cooling circuits in the region of the engine or the transmission. In order to be able to realize effective cooling, it is desirable to arrange the cooling structures through which a cooling liquid can flow, for example a cooler, as close as possible to the medium to be cooled. For this purpose, it is known inter alia to integrate tubular or tubular cooling structures in the housing or the housing wall of an engine or a transmission.

Nachteilhafterweise wird zur Ausbildung (Herstellung) von geeigneten Kühlstrukturen eine Vielzahl von Prozessschritten benötigt. Weiterhin wird die Baugröße durch die Integration rohr- oder schlauchartiger Kühlstrukturen in das Gehäuse erhöht. Ein weiterer Nachteil besteht in der hohen Fertigungszeit der Kühlstruktur, welche regelmäßig einen komplexen Verlauf (zum Beispiel labyrinthförmig oder mäanderförmig) aufweisen. Weiterhin nachteilig ist es, dass die Integration der Kühlstrukturen in ein Motor- oder ein Getriebegehäuse regelmäßig mit einem hohen Werkzeugverschleiß einhergeht, da Motor- beziehungsweise Getriebegehäuse regelmäßig aus stabilen Metallblöcken oder Metallstrukturen aufgebaut sind. Disadvantageously, a large number of process steps are needed to form (manufacture) suitable cooling structures. Furthermore, the size is increased by the integration of tubular or hose-like cooling structures in the housing. Another disadvantage is the high production time of the cooling structure, which regularly have a complex course (for example, labyrinth-shaped or meander-shaped). Another disadvantage is that the integration of the cooling structures in a motor or a gear housing is regularly accompanied by a high tool wear, since engine or transmission housing are regularly constructed of stable metal blocks or metal structures.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Gehäuse, insbesondere ein Gehäuse für einen Motor oder ein Getriebe eines Kraftfahrzeuges anzugeben, welches über Kühlstrukturen effizienter verfügt und schneller und kostengünstiger als die bekannten Gehäuse nach dem Stand der Technik herstellbar ist. Weiterhin soll ein Verfahren zur Erzeugung von Kühlstrukturen für ein Gehäuse, insbesondere für ein Gehäuse eines Motors oder eines Getriebes eines Kraftfahrzeuges angegeben werden, mit welchem die Kühlstrukturen in geringerer Zeit, mit höherer Präzision und Güte und mit einem geringeren Kostenaufwand hergestellt werden können. The invention is therefore based on the object to provide a housing, in particular a housing for an engine or a transmission of a motor vehicle, which has more efficient cooling structures and faster and cheaper than the known housing according to the prior art can be produced. Furthermore, a method for producing cooling structures for a housing, in particular for a housing of an engine or a transmission of a motor vehicle is to be specified, with which the cooling structures can be produced in less time, with higher precision and quality and at a lower cost.
Diese Aufgaben werden erfindungsgemäß durch die jeweils kennzeichnenden Merkmale des Anspruchs 1 und des Anspruchs 4 gelöst. These objects are achieved by the respective characterizing features of claim 1 and claim 4.
Hierzu ist es bei einem Gehäuse der o.g. Art erfindungsgemäß vorgesehen, dass die Nut mäanderförmig und labyrinthförmig ausgebildet ist, wobei die Kühlflüssigkeit die von einem erhitzten Medium in die Gehäusewand geleitete Wärme aufnimmt und abführt For this it is in a case of o.g. Art according to the invention provided that the groove is formed meander-shaped and labyrinth-shaped, wherein the cooling liquid receives the heat conducted by a heated medium in the housing wall and dissipates
Weiterhin ist es bei einem Verfahren der o.g. Art erfindungsgemäß vorgesehen, dass mittels elektrochemischen Abtragens oder mittels funkenerosiven Abtragens die Nut mäanderförmig oder labyrinthförmig ausgebildet wird und somit durch die Kühlflüssigkeit die von dem erhitzten Medium in die Gehäusewand geleitete Wärme aufnehmbar und abführbar ist. Furthermore, in a method of the above-mentioned. Art according to the invention provided that by means of electrochemical removal or by spark erosive removal, the groove is formed meandering or labyrinth-shaped and thus by the cooling liquid, the heat conducted by the heated medium in the housing wall heat is absorbable and dissipatable.
Die Nuten weisen vorzugsweise eine Breite kleiner als 2 mm und eine Tiefe kleiner als 5 mm auf. Insbesondere bei komplexen Kühlstrukturen ist die Ausbildung mittels Schläuchen oder Rohren äußerst kompliziert und zeitintensiv. Um eine Integration der Schläuche oder Rohre in das Gehäuse beziehungsweise im Bereich des Gehäuses zu realisieren, wäre beispielsweise ein werkzeugverschleißendes Fräsen aus dem vollen oder aus dem vorgegossenen Material (Gehäusewand) notwendig. Dies kann durch das elektrochemische Senken beziehungsweise das funkenerosive Senken vermieden werden. Das elektrochemische Abtragen beruht auf der Auflösung eines als Anode (positiv) polarisierten metallischen Werkstoffs in einem elektrisch leitenden Medium. Das funkenerosive Abtragen beruht auch auf dem Abtragen dadurch, dass sich die elektrische Ladungsdifferenz zwischen Elektrode und Werkstück durch einen Lichtbogen entlädt und so Material an Elektrode und Werkstück abgeschmolzen wird. The grooves preferably have a width of less than 2 mm and a depth of less than 5 mm. Especially with complex cooling structures, the formation by means of hoses or pipes is extremely complicated and time-consuming. In order to realize an integration of the hoses or pipes in the housing or in the region of the housing, for example, a tool-wearing milling from the full or from the precast material (housing wall) would be necessary. This can be avoided by electrochemical sinking or spark erosion sinking. The electrochemical ablation is based on the dissolution of an anode (positive) polarized metallic material in an electrically conductive medium. The spark erosion ablation is also based on the removal by the fact that the electrical charge difference between the electrode and the workpiece is discharged by an arc and so material is melted to the electrode and workpiece.
Durch das elektrochemische Abtragen kann die Abtragsrate zur Oberflächenqualität (besser als feingeschlichtet) optimiert werden. Die hohe Oberflächengüte verbessert die Anströmung des Mediums an die Strukturwände und verbessert dadurch den Wärmeübergang und somit die Effizienz der Kühlung. By electrochemical removal, the removal rate can be optimized for surface quality (better than fine-grained). The high surface quality improves the flow of the medium to the structure walls and thus improves the heat transfer and thus the cooling efficiency.
Weitere bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den übrigen, in den Unteransprüchen genannten Merkmalen. Further preferred embodiments of the invention will become apparent from the remaining, mentioned in the dependent claims characteristics.
