Definitions

  • the invention relates to an oil cooler, in particular for a an internal combustion engine downstream transmission with at least an oil circuit arranged in a housing with a Oil inlet and an oil outlet opening and with at least one cooling circuit through which a cooling medium flows.
  • Oil coolers usually have one essentially cuboid housing, which inlet and outlet channels for the oil to be cooled and inlet and outlet channels for the Has coolant.
  • a stacked disc design trained oil cooler is described, for example, in DE 197 11 258 C2 described and consists of several trough-shaped plates, to form neighboring hollow chambers with their raised edges stacked one inside the other at a distance and are soldered.
  • Oil coolers can, for example, on a Side surface of the engine block (EP 0 243 138 B1) or on one Vehicle body part (DE 40 23 042 A1) are attached. Prepared because of the limited space in the engine compartment the housing of the oil cooler is often difficult. Of Also looking for designs that improve the Heat exchange between the oil to be cooled and the Bring coolant with you.
  • the object underlying the invention is seen in to specify an oil cooler of the type mentioned, by which can overcome the aforementioned problems.
  • 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.
  • the oil cooler should improved heat exchange between the oil to be cooled and allow the coolant.
  • 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.
  • the oil cooler can be in the area of a shaft be arranged so that the shaft through the recess extends.
  • 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 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the Central axis of the peripheral surface and the central axis of the Recess are offset from each other.
  • the slot is roughly in the direction of the offset is aligned.
  • the Slot through a ring portion of the housing on which the Ring has its greatest width.
  • 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.
  • 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.
  • the ratio of the thickness of the housing is preferably increased Diameter of the housing in the order of 1: 4 to 1: 12th
  • the oil cooler shown in Figures 1 and 2 consists in Essentially from a cooler housing 10, which is on a Base plate 12 is attached.
  • the cooler housing 10 closes a heat exchanger designed in a known plate construction one in which the circumferential housing wall through the upstanding edges of the nested, at a distance stacked and soldered tub-shaped plates formed becomes.
  • the outer shape of the cooler housing 10 forms a flat, slotted ring, the cross section of which is essentially is rectangular.
  • the base plate 12 is also annular trained, but not slotted. It contains three Fastening tabs 14 with holes that attach to serve a component in the engine area of a vehicle.
  • the outer jacket 16 of the oil cooler i.e. H. the outer jacket of the Radiator housing 10 and the base plate 12 is cylindrical trained and has its outer jacket cylinder axis at A.
  • Die inner recess 18 of the oil cooler is also cylindrical trained and has its recess cylinder axis at B.
  • Die two cylinder axes A and B do not coincide but are offset from each other by a distance a. This gives itself a ring, the cross-section of which is not in the circumferential direction is constant, but different radial dimensions having.
  • the radius of the recess 18 is the same Order of magnitude like the radial width of the ring.
  • the radial Ring width is in the illustrated embodiment on one Side of the ring slightly lower and on the other, opposite side of the ring slightly larger than the radius the recess 18.
  • the oil cooler housing has one Slot 20 on the entire thickness of the Radiator housing 10 between the recess 18 and the Outer jacket 16 extends.
  • the width of the slot 20 is compared to the diameter of the recess 18 relative low.
  • the inlet and Outlet connections for the oil circuit and not shown the coolant circuit, not shown.
  • the connections are arranged near the slot to make oil channels as long as possible and coolant channels that are essentially concentric extend within the oil cooler housing to allow. It are an oil inlet 22, an oil outlet 24, a coolant inlet 26 and a coolant outlet 28 are provided. Every connection is provided with an associated hose connector to which a corresponding oil hose or coolant hose can be connected.
  • the diameter of the outer jacket 16 is about eight times as large like the thickness of the oil cooler case.
