Definitions

  • the invention relates to an oil cooler for an internal combustion engine, comprising a plurality of disk bodies arranged in a stack in a housing through which coolant flows, the lower part of which is formed by one (13) of two matching plates and the cover of which is formed by the second plate (14), the edges ( 16, 18) of the spaced, profiled plates (13, 14) are soldered and enclose a cavity through which the oil to be cooled flows and which is connected to the cavities of adjacent disk bodies via flow openings (24, 25).
  • Disc oil coolers are known (DE-AS 28 43 423).
  • the plates forming the outer walls of the oil-flowing chambers are pushed onto a central tube and lie down with collars arranged in the area of the pipe and projecting outwards and with collars arranged in the area of their outer circumference. pronounced edges loosely to each other.
  • Turbulence inserts are inserted between each plate forming an oil chamber. The boards stacked in this way are then soldered. Care must be taken to ensure that the respective inner and outer edges of the plates are sufficiently firmly in contact with the associated parts of adjacent plates, because otherwise reliable soldering cannot be achieved. This is relatively expensive.
  • An oil cooler of the type mentioned at the outset is also known (WO 88/04761).
  • Flat tube bodies for oil coolers are provided there, which are each made up of two elongated plate halves. These plate halves are provided with all-round edges that overlap and are soldered. It is difficult here to hold the parallel longitudinal edges of the plate halves so tightly together in all areas for the soldering process that the desired soldering gap is reached at every point.
  • the present invention has for its object to simplify a disc oil cooler of the type mentioned in terms of manufacturing technology.
  • the edges are coordinated so that the outer edge is held in place and under tension on the inner edge.
  • This measure allows the individual disk bodies to be joined together in a relatively simple manner, prior to the soldering process, in the manner of a can, and can also hold the turbulence inserts assigned to them without the aid of assembly devices. If the disc bodies formed in this way are then pushed onto the tube, since the two plates belonging together are already centered against one another, there is also no fear of canting.
  • the advantage is also achieved that the latching edges, which are held in one another under pretension, form the desired narrow soldering gap all around the circumference and thus ensure tight soldering.
  • soldering material for example in the form of soldering foils
  • the plates can be solder-plated in a simple manner, so that the insertion of solder foils is eliminated.
  • Claim 2 there thereby the guarantee that the required bracing is maintained uniformly over the entire circumference and not, as in the prior art, is impossible due to straight edges.
  • the features of claims 3 and 4 offer the advantage that the disk body can be placed on one another and joined together in a simple manner.
  • Claim 5 has the advantage that the two plates forming the cavity do not have to be kept at a mutual distance by separate measures. They are arranged at the correct distance from one another after pretensioning their outer edges. The distance to adjacent disk bodies can be ensured by the measures of claim 6.
  • the measures of claim 7 ensure the simple positioning of the disk body on the central mounting tube, while at the same time maintaining the mutual spacing of the plates on the inside diameter.
  • the features of claim 8 ensure the flow through the cavities, the type of flow depending on the selected housing shape.
  • a can-shaped housing (1) of a disc oil cooler can be seen, which is cup-shaped and is closed at the bottom by an attached bottom (2) which overlaps the free edge of the cup-shaped housing (1) on the outside.
  • the housing (1) is provided with an inlet connection (3) for the cooling liquid, which is usually the cooling water of the Is the engine on which the oil cooler for cooling the engine oil is attached.
  • the housing (1) also has an outlet connection (4) for the cooling water.
  • Inlet and outlet connections (3, 4) are closed off from one another by a partition on the water side, which - as will be explained later (FIGS. 10, 11) - is formed by an expression (30) on the disk bodies. As shown in Fig.
  • an inflow opening (5) for the oil to be cooled is provided on the top of the pot-like housing (1), which is then supplied to the housing (1) in a manner not shown in the direction of arrow (6) flows through the disc body to be explained and leaves the housing (1) through an outlet opening (7) at the bottom (2) in the direction of the arrow (8).
  • the oil therefore enters and exits transversely to the flow of the cooling water indicated by the arrows (9) in FIG. 1.
  • Fig. 4 shows that the disc oil cooler in the interior of the housing (1) is constructed from a plurality of disc bodies (10) which are stacked one above the other in the interior of the pot-like housing (1) and each with a central opening (11) (see Fig 5, 6, 10 and 11) are pushed onto a tube (12) running centrally in the housing (1), the longitudinal axis of which extends parallel to the outer walls of the pot-like housing (1).
  • each disk body (10) consists of two plates (13 and 14) which are assigned to one another, of which the plate (14) shown in FIGS. 5 and 6 is the cover and that in FIGS.
  • the plate (13) shown forms the lower part of a disk body (10), which is designed in the manner of a can and also accommodates a turbulence insert (15) in its cavity, which improves the heat transfer between the oil flowing through the disk body (10) and to increase the cooling water flowing around the disc body (10).
  • the plates (13 and 14) are both circular.
  • the embodiment of FIGS. 1 to 4 is provided for the use of the oil cooler with an oil filter, which connects to the side of the oil cooler of FIG. 4 facing the outlet opening (7) in a manner not shown. The oil cleaned by the oil filter is then returned to the engine through the opening in the sleeve (12).
  • the space adjacent to the outlet opening (7) can therefore be sealed off within the circumferential housing bulge and, as shown in dashed lines in FIG. 1 and 4 is indicated, in the sleeve (12) a slot (31) running longitudinally on one side is provided, through which in this case the oil from the individual disk bodies, with the outlet opening (7) closed, directly into the sleeve (12) and from there can flow back again.
  • the plate forming the cover (14) has an outer circumferential edge (16) directed towards the lower part (13), the free end of which slightly follows is bent on the outside and thus forms an internal chamfer (17) which facilitates the sliding of the edge (16) over the edge (18) of the plate (13) forming the lower part (FIG. 12).
  • the free end of the edge (18) of the plate (13) is directed somewhat inwards, so that there is an external chamfer (19).
  • the edge (16) of the plate (14) has its largest inside dimension approximately in the middle.
  • a circumferential recess (20) is provided here, which has an obtuse-angled cross section with an apex directed outwards.
  • the edge (18) is designed such that it has a shape on the outside which corresponds approximately to the obtuse-angled cross-section of the edge (16), the apex of the obtuse angle also being directed outwards, so that a peripheral edge (21) arises when you press into each other of the lid and lower part of a disc body (10), that is, when the plates (14 and 13) are pressed together into the recess (20) of the outer edge (16).
  • the dimensions are chosen so that the edges (16 and 18) lie against each other under tension on the entire circumference. Such a prestress could also be achieved if the plates are designed elliptical or egg-shaped. It could not be achieved with an oval shape, because no defined elastic contact force is possible on the parallel longitudinal sides.
  • the plate (13) also has an indentation (30) which extends radially outward from the shape (23) of the left opening (FIG. 11) and which, as indicated in FIG. 1, has a partition between the inflow connector (3 ) and the drain port (4) for the cooling liquid, which is forced in this way to flow in the space between two disc bodies (10) the path marked in Fig. 1 with the arrows (9).
  • the plate (14) forming the cover of the disc body (10) is designed differently in the area of the inner opening (11). they does not have an edge framing the opening (11), but instead is provided in the region of two kidney-shaped openings (25) also opposite the opening (11) with only one web (26) provided on the inner edge of the respective opening (25), the the opening (25) bounds inwards and extends to just before the edge of the opening (24) of the other plate.
  • the webs serve to guide the oil flow and have the effect that the oil must flow through the disks in the sense of the arrows shown in broken lines in FIG. 6 and does not flow from an opening (25) from the inside to the opposite opening.
  • each of the approximately circular plates (14) is provided with outwardly directed button-like features (27) which are evenly distributed over the circumference and serve to provide support against adjacent disc bodies.
  • the features (27) of the plate (14) are based on corresponding features (28) of the plate (13) (see FIGS. 10, 11 and 13), the height of which also corresponds to half the distance between adjacent disk bodies.
  • the forms (23) provide support for adjacent pane bodies in the inner region of the pane bodies (10), this is achieved by the forms (27 and 28) in the outer region of the pane bodies.
  • the base (2) is put on, which ensures that all the disk bodies are pressed against one another with the necessary axial force.
  • the pre-assembled disc oil coolers are then soldered in a soldering oven. The selected design results in a good and tight connection of all parts.
