Definitions

  • the invention relates to an oil cooler for internal combustion engines according to the preamble of claim 1, in particular for installation between the engine and an oil filter (GB-A 1097357).
  • Oil coolers of this type are known in the form of disc coolers (DE-AS 2 843 423).
  • disc coolers In these disk coolers, a plurality of hollow disks are arranged in a housing through which the cooling water flows and in parallel to one another, through which the oil flows and around which the cooling water flows.
  • Such disc coolers have to be produced in a relatively complex manner, in which soldering or welding processes are necessary. They also have a relatively high weight and an insufficient cooling capacity for some applications.
  • an oil cooler is also known in which the hot oil coming from the internal combustion engine is passed through a pipe coil arranged inside a housing through which water flows.
  • This type of construction is also complex to manufacture because the pipe coil also has to be welded or soldered there.
  • the invention is therefore based on the object of providing an oil cooler of the type mentioned at the outset, which can be produced more easily and without a soldering or welding process.
  • the entire structure of the oil cooler is very simple because the coolant collection spaces are formed by the two opposing floors and a hood-shaped water box each, and it is then possible to design the housing chamber as a frame that is open on two sides, with the water boxes in the open sides used with seals and are each held by a flanged edge of the housing chamber. No soldering process is necessary for this either.
  • the tubes provided in the heat exchanger body can be those with an annular cross section, the ends of which are sealed in the bases by widening and / or by inserting sealing rings.
  • the tubes can in turn be connected via a plurality of ribs or fins, which lie essentially in planes running perpendicular to the longitudinal direction of the tubes and around which the oil flows, to form a tube fin block which is tightly clamped in the housing chamber with the bottoms provided on its two end sides before the two water boxes are put on.
  • a circumferential seal can be provided between the bottoms and the housing chamber.
  • the housing chamber can have a continuous bore extending transversely to the tubes of the heat exchanger body, through which a hollow connecting piece can be passed in a simple manner, one end of which can be screwed to a motor and the other end of which can be screwed to an oil filter.
  • the housing chamber can rest against the engine via a circumferential seal, oil inlet openings being able to be provided within the region of this seal and the space enclosed by the seal being connected to at least one connection opening to the engine.
  • the hot engine oil thereby enters the housing chamber through the oil inlet openings, flows past the pipes through which the coolant, for example water, flows, and past the fins and expediently enters a ring space of the filter via a plurality of outlet openings, these outlet openings again lead into a room that is delimited by a circumferential seal from the oil filter.
  • the two spaces enclosed by seals on both sides of the housing chamber can each be formed by a peripheral edge of the housing chamber, on the front side of which the seal is arranged.
  • connection socket and the drain socket for the coolant on the same side of the oil cooler for installation reasons, one of the two water boxes can finally be provided with both connection nozzles and with a partition between the inlet and outlet nozzles, so that the coolant can only be provided by one Part of the pipes in one direction and then after the deflection in the other water tank through the second part of the pipes can flow back into the first water tank.
  • the oil cooler shown in FIG. 1 is designated as a whole by 1. It has a housing chamber 2, which consists of a central part 2a, essentially designed as an open frame, with two opposite closed end walls 2b and two opposite side walls 2c, in each of which a hood-shaped water tank 2d or 2e is inserted on the other two open sides.
  • the middle part 2a forms a housing part into which a heat exchange body in the form of a tube fin block 18 is inserted.
  • the tube fin block 18 consists of a plurality of tubes 11a, 11b, 11c and 17a, 17b, which are arranged parallel to one another, into which turbulence inserts (not shown) can be inserted, and of lamellar fins 18a which lie in planes perpendicular to the axes of the tubes 11 a to 11 c and 17a and 17b run. These lamellar ribs 18a thus enlarge the heat exchange surface in a known manner. They are solderless with the tubes 11 to 11 c or 17a, 17b, e.g. connected by expanding the pipes and are in thermal contact with them.
  • the ends of the tubes 11a to 11c and 17a and 17b are inserted in trays 8 and 13, which are inserted into the middle part 2a after insertion of the tube fin block 18 from both sides with the interposition of a seal 13a and 8a and then be jammed against the middle part 2a.
  • This can be done by widening the free ends of the tubes 11 to 11c or 17a, 17b which protrude beyond the tube sheets 8 or 13, so that on the one hand they are pressed tightly into the tube sheets and on the other hand they are pressed towards one another and thus against one another press the seals 13a, 8a and the middle part 2a.
  • the middle part 2a which is closed off by the tube sheets 8 and 13 on both sides, which are initially still open, is then closed off from the outside by the hood-shaped water boxes 2d and 2e, which together with the bottoms 8 and 13 form cooling liquid collecting spaces 7, 9 and 15, through which the cooling water supplied through a connection piece 3 in the direction of arrow 4 can flow out in the direction of arrow 15 to a discharge pipe 5 and from there in the direction of arrow 6.
  • Inlet and outlet ports 3 and 5 are attached to the water tank 2d, which is also provided with a partition 10, which sits tightly on the associated floor 8 of the upper water tank.
  • the pipes are divided into two groups, the cooling water flowing down through the pipes 11a to 11c into the collecting space 15, being deflected there and passing through the pipes 17a, 17b into the cooling liquid collecting space 9 of the upper water tank 2d and from there emerges in the direction of arrow 6.
  • the two water boxes 2d and 2e are firmly connected to the middle part 2a in that an edge 2f of the middle part 2a is flanged over an edge of the water boxes 2d and 2e, so that the latter against the assigned floors 8 and 13 and against seals 12 are pressed, which produce the seal between the water tanks 2d, 2e and the associated floors 8 and 13.
  • the entire structure of the oil cooler 1 can therefore be carried out without a soldering or welding process.
  • the middle part 2a is provided on the sides 2c, which run approximately perpendicular to the side walls 2b, with a plurality of openings 19, which in the exemplary embodiment are designed as bores, which allow access to the interior of the housing chamber 2. Openings 25 of the same configuration are provided on the opposite side.
  • the openings 19 and 25 each open into an annular space 26a and 26b, which is open to the outside and is delimited by a peripheral edge 30a and 30b.
  • An inserted sleeve 21 runs centrally through the housing chamber 2 and is guided through corresponding openings in the side walls 2c and in the tube fin block 18. This sleeve 21 and the openings 19 and 25 are intended for the oil flow.
  • the oil initially flows, for example in the direction of arrow 22, through the openings 25 into the housing chamber, flows around the tube fin block 18 and emerges again in the direction of arrow 23 from the openings 19, flows through an oil filter, for example, and then returns in the direction of arrow 24a and 24b back through the sleeve 21 to the motor, as is clear from FIG. 3.
  • FIG. 4 shows the oil cooler in the representation according to FIG. 3, however, in the installed state, the connecting parts also being shown partly in section.
  • the engine block 40 of an internal combustion engine shown as a detail is provided with a bore 34, which is provided with an internal thread at its outer end.
  • a hollow connecting piece 28 is screwed into this internal thread and is inserted through the opening 20 of the oil cooler 1.
  • an oil filter 29 is screwed onto the connecting piece 28.
  • the oil cooler 1 is sealed off from the engine block 40 by a circumferential seal 36 which is inserted into a groove in the edge 30b. Opposite the oil Filter 29, the oil cooler 1 is sealed by a circumferential seal 31 which bears on the outside on the end face of the edge 30a.
  • the oil filter 29 has openings 35 through which the oil flowing out of the openings 19 (FIG. 3) in the direction of the arrow 23 can penetrate into the filter 29, is deflected there and through the opening 33 of the connecting piece 28 to the bore 34 of the engine block 40 arrives and from there is returned to the engine.
  • the uncleaned and hot engine oil passes through a connection channel 32 in the engine block 40 into the space 26b, from there through the openings 25 into the housing chamber 2 and, as already described with reference to FIG. 3, is guided past the tube fin block 18, through which the cooling water flows is.
  • the new oil cooler Due to its design, the new oil cooler has manufacturing advantages. But it also has a much larger cooling capacity and a much lower volume resistance for the oil, which can therefore be passed through the cooler and filter in larger quantities.
