Die der Erfindung zugrunde liegende Aufgabe wird darin gesehen, einen Ölkühler der eingangs genannten Art anzugeben, durch welchen sich die vorgenannten Probleme überwinden lassen. Insbesondere soll der Ölkühler so ausgebildet sein, dass er beengten Bauräumen dadurch Rechnung trägt, dass sich bisher nicht geeignete Bauräume für die Montage des Ölkühlers erschließen lassen. Des Weiteren soll der Ölkühler einen verbesserten Wärmeaustausch zwischen dem zu kühlenden Öl und der Kühlflüssigkeit ermöglichen.The object underlying the invention is seen in to specify an oil cooler of the type mentioned, by which can overcome the aforementioned problems. In particular, the oil cooler should be designed so that it cramped installation space takes into account that up to now Unsuitable installation space for mounting the oil cooler open up. Furthermore, the oil cooler should improved heat exchange between the oil to be cooled and allow the coolant.
Die Aufgabe wird erfindungsgemäß durch die Lehre des Patentanspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung gehen aus den Unteransprüchen hervor. The object is achieved by the teaching of Claim 1 solved. Further advantageous configurations and further developments of the invention result from the subclaims out.
Der erfindungsgemäße Ölkühler enthält wenigstens einen in einem Gehäuse angeordneten Ölkreis mit einer Öleinlass- und einer Ölauslassöffnung und wenigstens einen von einem Kühlmedium durchströmten Kühlkreis. Er zeichnet sich dadurch aus, dass das Gehäuse flach oder scheibenförmig ausgebildet ist, so dass die Höhe bzw. Dicke des Gehäuses wesentlich geringer ist als die seitlichen Ausmaße, wie Länge und Breite des Gehäuses. Durch einen mittleren Bereich der Gehäusescheibe erstreckt sich quer oder senkrecht zur Scheibenoberfläche eine Ausnehmung, welche die gesamte Dicke des Gehäuses durchdringt. Diese Ausnehmung ist an andere Maschinenelemente derart angepasst, dass diese sich ganz oder teilweise in die Ausnehmung erstrecken können. Beispielsweise kann der Ölkühler im Bereich einer Welle derart angeordnet sein, dass sich die Welle durch die Ausnehmung erstreckt.The oil cooler according to the invention contains at least one in one Housing arranged oil circuit with one oil inlet and one Oil outlet opening and at least one of a cooling medium flowed cooling circuit. It is characterized by the fact that Housing is flat or disc-shaped, so that the Height or thickness of the housing is significantly less than that lateral dimensions, such as length and width of the housing. By a central area of the housing disc extends transversely or a recess perpendicular to the surface of the pane, which penetrates the entire thickness of the housing. This recess is adapted to other machine elements in such a way that can extend completely or partially into the recess. For example, the oil cooler can be in the area of a shaft be arranged so that the shaft through the recess extends.
Bevorzugt wird dieser Ölkühler zwischen einem Verbrennungsmotor und einem dem Verbrennungsmotor nachgeschalteten und zu diesem beabstandeten Aggregat angeordnet, die über eine Antriebswelle, beispielsweise eine Kardanwelle, miteinander verbunden sind. Das angetriebene Aggregat kann beispielsweise ein dem Verbrennungsmotor nachgeordnetes Getriebe sein. Die Antriebswelle erstreckt sich dabei durch die Ausnehmung des Ölkühlers. Diese Ausbildung und Anordnung des Ölkühlers ermöglicht es, den Zwischenraum zwischen Verbrennungsmotor und Getriebe zu nutzen. Der Ölkühler lässt sich somit an einem besonders günstigen Ort platzieren, der nicht durch andere Bauelemente beansprucht wird. Der Ölkühler dient vorzugsweise der Kühlung eines dem Verbrennungsmotors nachgeschalteten Aggregats. Der Ölkühler kann derart ausgebildet werden, dass er relativ flach ist, so dass er auch von einer relativ schmalen Lücke zwischen Verbrennungsmotor und Getriebe aufgenommen werden kann ohne zusätzlichen Bauraum im beengten Motorbereich zu beanspruchen. Andererseits kann der Ölkühler trotz seiner kompakten Bauweise relativ große Radialmaße aufweisen, was insbesondere die Ausbildung langer Kühlkanäle und einen guten Wärmeaustausch ermöglicht. This oil cooler between an internal combustion engine is preferred and a downstream of the internal combustion engine and to this spaced-apart unit arranged via a drive shaft, for example, a cardan shaft, are connected to each other. The driven unit can, for example, a Internal combustion engine subordinate gear. The The drive shaft extends through the recess of the Oil cooler. This training and arrangement of the oil cooler allows the gap between the internal combustion engine and To use gears. The oil cooler can thus be attached to one place particularly cheap, not by others Components is claimed. The oil cooler is preferably used the cooling of a downstream of the internal combustion engine Aggregate. The oil cooler can be designed such that it is relatively flat, so it is also of a relatively narrow Gap between internal combustion engine and gearbox added can be done without additional installation space in the confined engine area to claim. On the other hand, the oil cooler can despite its compact design have relatively large radial dimensions, what especially the formation of long cooling channels and a good one Allows heat exchange.
Vorzugsweise schließt das Gehäuse einen in Plattenbauweise ausgebildeten Wärmetauscher ein. Dabei wird die umlaufende Gehäusewandung beispielsweise durch die hochstehenden Ränder der ineinanderliegenden, auf Abstand gestapelten und verlöteten wannenförmigen Platten gebildet. Der Wärmetauscher kann auf einer Grundplatte befestigt sein, wobei sich die Ausnehmung sowohl durch das Gehäuse als auch durch die Grundplatte erstreckt. Die Grundplatte ist mit Befestigungselementen versehen, die der Befestigung des Ölkühlers am Motorblock oder einem anderen Bauelement dienen. Durch die Verwendung einer Grundplatte werden Spannungen, die infolge der Befestigung auftreten können, von dem Wärmetauscher fern gehalten.The housing preferably includes a plate construction trained heat exchanger. The circumferential Housing wall, for example, by the raised edges the one inside the other, stacked and soldered at a distance trough-shaped plates formed. The heat exchanger can open be attached to a base plate, the recess both through the housing and through the base plate extends. The base plate is with fasteners provided that the attachment of the oil cooler to the engine block or serve another component. By using a Base plate are stresses resulting from the attachment can occur, kept away from the heat exchanger.
Die Ausnehmung kann sich in einem Randbereich des Ölkühlers befinden und an benachbarte Bauelemente angepasst sein. Besonders vorteilhaft ist es jedoch, wenn sich die Ausnehmung im Wesentlichen zentral durch das Gehäuse und gegebenenfalls durch die Grundplatte erstreckt, so dass die Ausnehmung von dem Ölkühler eingeschlossen ist.The recess can be in an edge area of the oil cooler are located and adapted to neighboring components. However, it is particularly advantageous if the recess essentially centrally through the housing and possibly extends through the base plate so that the recess of the Oil cooler is included.
Eine bevorzugte Ausgestaltung der Erfindung sieht vor, dass die Ausnehmung in etwa einen kreisförmigen Querschnitt aufweist. Sie ist damit besonders für die Durchführung von Wellen und dergleichen geeignet, wie es bereits erwähnt wurde.A preferred embodiment of the invention provides that the Recess has approximately a circular cross section. It is therefore particularly suitable for carrying out waves and the same suitable as already mentioned.
Des Weiteren ist es von Vorteil, die Umfangsfläche des Gehäuses und/oder der Grundplatte im Wesentlichen kreisförmig auszubilden, so dass die äußere Kontur des Ölkühlers im Wesentlichen eine kreisrunde Scheibe darstellt. Die Kanäle des Ölkreises und des Kühlkreises können hierbei im Wesentlichen in Umfangsrichtung und konzentrisch zur Scheibenachse verlaufen. Hierdurch ergeben sich lange Kühlkanäle, die einen guten Wärmeaustausch begünstigen.Furthermore, it is advantageous for the peripheral surface of the housing and / or the base plate is essentially circular train so that the outer contour of the oil cooler in the It essentially represents a circular disc. The channels of the Oil circuit and the cooling circuit can essentially in Run circumferentially and concentrically to the disc axis. This results in long cooling channels that are good Favor heat exchange.
Die genannten Vorzüge treten bei einer bevorzugten Weiterbildung der Erfindung besonders hervor, bei der das Gehäuse und/oder die Grundplatte ringartig ausgebildet sind, so dass das Gehäuse und/oder die Grundplatte im Wesentlichen kreisförmige Umfangsflächen und im Wesentlichen kreisförmige mittlere Ausnehmungen aufweisen.The advantages mentioned occur with a preferred Further development of the invention is particularly evident in that Housing and / or the base plate are ring-shaped, so that the housing and / or the base plate essentially circular peripheral surfaces and substantially circular have medium recesses.
Bei einem als Ringscheibe ausgebildeten Ölkühler hat es sich als zweckmäßig erwiesen, wenn der Durchmesser der Ausnehmung von der gleichen Größenordnung ist wie die Breite der die Ausnehmung umgebenden Scheibenoberfläche. Eine gleiche Größenordnung liegt dann vor, wenn die Abmessungsverhältnisse innerhalb eines Rahmens von 1 : 3 oder 3 : 1 liegen.In the case of an oil cooler designed as an annular disc, it did proven to be useful if the diameter of the recess is of the same order of magnitude as the width of the Recess surrounding disc surface. The same Magnitude is when the dimensional relationships are within a 1: 3 or 3: 1 range.
Es kann für eine Reihe von Anwendungsfällen zweckmäßig sein, wenn die Mittelachse der Umfangsfläche des Ölkühlers und die Mittelachse der Ausnehmung nicht miteinander fluchten, sondern zueinander versetzt sind. Bei einer ringförmigen Ausbildung bedeutet dies, dass über den gesamten Umfang die Ringbreite nicht konstant ist, sondern einen in radialer Richtung breiteren Bereich und einen schaleren Bereich aufweist. Diese Ausbildung ermöglicht eine optimale Anpassung an die jeweiligen räumlichen Verhältnisse. Sie hat auch den Vorzug, dass die Einlass- und Auslasskanäle an der breiteren Seite angeordnet werden können, wo ausreichender Platz zur Verfügung steht.It can be useful for a number of applications when the central axis of the peripheral surface of the oil cooler and the The central axis of the recess is not in alignment, but rather are offset from each other. With an annular formation this means that over the entire circumference the ring width is not constant, but one in the radial direction has a wider area and a narrower area. This Training enables optimal adaptation to the respective spatial relationships. It also has the advantage that the Inlet and outlet channels arranged on the wider side where there is sufficient space available.
Vorzugsweise ist ein ringförmiges Ölkühlgehäuse als geschlitzter Ring ausgebildet, wobei zwischen der Ausnehmung und der äußeren Umfangsfläche des Gehäuses ein radial verlaufender Schlitz oder Spalt ausgebildet ist, der sich durch die gesamte Ringdicke erstreckt und einen zentralen Ausnehmungsbereich mit der Umfangsfläche des Gehäuses verbindet. Auf einer Seite des Schlitzes können die Einlassöffnungen und auf der anderen Seite die Auslassöffnungen des Ölkreises und/oder des Kühlmittelkreises angeordnet sein. Die Ölkanäle des Ölkreises und/oder die Kühlmittelkanäle des Kühlkreises verlaufen dabei innerhalb des Ringes und vorzugsweise in Umfangsrichtung. Die Grundplatte bildet vorzugsweise einen geschlossenen, nicht geschlitzten Ring, um eine ausreichende Stabilität des Ölkühlers zu gewährleisten. Preferably, an annular oil cooling housing is as slotted ring formed, between the recess and the outer peripheral surface of the housing a radial extending slot or gap is formed which through extends the entire ring thickness and a central Recess area with the peripheral surface of the housing combines. On one side of the slot, the Inlet openings and on the other side the outlet openings the oil circuit and / or the coolant circuit. The oil channels of the oil circuit and / or the coolant channels of the The cooling circuit runs inside the ring and preferably in the circumferential direction. The base plate forms preferably a closed, unslit ring to to ensure sufficient stability of the oil cooler.
Wie bereits erwähnt wurde, kann es zweckmäßig sein, dass die Mittelachse der Umfangsfläche und die Mittelachse der Ausnehmung zueinander versetzt sind. Hierbei ist es des Weiteren von Vorteil, dass der Schlitz in etwa in der Richtung des Versatzes ausgerichtet ist. Vorzugsweise erstreckt sich der Schlitz durch einen Ringabschnitt des Gehäuses, an welcher der Ring seine größte Breite aufweist. Durch die vergrößerte Ausbildung der Ringenden wird ein ausreichender Raum für die Anordnung der Einlass- und Auslasskanäle bereitgestellt.As already mentioned, it may be appropriate for the Central axis of the peripheral surface and the central axis of the Recess are offset from each other. Here it is the Another advantage is that the slot is roughly in the direction of the offset is aligned. Preferably, the Slot through a ring portion of the housing on which the Ring has its greatest width. By the enlarged Training the wrestlers will be sufficient space for that Arrangement of the inlet and outlet channels provided.
Der Schlitz kann prinzipiell relativ schmal ausgebildet seinund wird an die jeweiligen Fertigungsbedingungen angepasst. Seine Breite ist wesentlich kleiner als der Querschnitt der Ausnehmung ist. Durch die Ausbildung eines nahezu geschlossen Ringes können relativ lange Kanäle für den Ölkreis und den Kühlkreis ausgebildet werden.In principle, the slot can be made relatively narrow and is adapted to the respective manufacturing conditions. Its width is much smaller than the cross section of the Recess is. Almost closed by training one Ringes can have relatively long channels for the oil circuit and the Cooling circuit are formed.
Eine für die Führung des Ölkreises und des Kühlkreises optimale Lage ergibt sich durch eine Anordnung der zugehörigen Einlassund Auslassöffnungen unmittelbar beiderseits des Schlitzes, wobei alle Öffnungen auf einer der Scheibenoberflächen des Ölkühlergehäuses austreten. Bei vielen Anwendungsfällen sind in diesem Bereich die räumlichen Verhältnisse nicht beengt, so dass eine mühelose Verlegung der Zu- und Ableitungen erfolgen kann.An optimal one for guiding the oil circuit and the cooling circuit Location results from an arrangement of the associated inlet and Outlet openings immediately on either side of the slot, with all openings on one of the disc surfaces of the Exit the oil cooler housing. For many applications, in this area is not cramped, so that the supply and discharge lines can be laid effortlessly can.
Vorzugsweise liegt das Verhältnis von Dicke des Gehäuses zu Durchmesser des Gehäuses in der Größenordnung von 1:4 bis 1: 12.The ratio of the thickness of the housing is preferably increased Diameter of the housing in the order of 1: 4 to 1: 12th
