Definitions

  • the invention relates to an oil cooler for internal combustion engines, in particular for installation between the engine and an oil filter with at least one heat exchange space through which the 01 to be cooled and one through which a cooling liquid, in particular water flows, which adjoin one another.
  • Oil coolers of this type are known in the form of disc coolers (DE-AS 28 43 423).
  • disc coolers a plurality of hollow discs are arranged in a housing through which the cooling water flows and parallel to one another and through which the oil flows and around which the cooling water flows.
  • a disadvantage of these disc coolers is the relatively complex type of manufacture, which requires soldering or welding processes.
  • Another disadvantage is the relatively high weight and the insufficient cooling capacity for some applications.
  • the invention has for its object to provide an oil cooler of the type mentioned, which is easier to manufacture and without a soldering or welding process.
  • the heat-exchange chamber through which the oil flows is designed as a housing chamber into which a heat-exchange body through which the coolant flows, which consists of a multiplicity of parallel tubes, the ends of which are each held in a bottom of a coolant-collecting space.
  • a heat-exchange body through which the coolant flows which consists of a multiplicity of parallel tubes, the ends of which are each held in a bottom of a coolant-collecting space.
  • the entire structure of the oil cooler can be made very simple if the coolant collection spaces are formed by the two opposing floors and a hood-shaped water tank, because it is then possible to design the housing chamber as a frame that is open on two sides, in the open sides of which the water boxes are inserted 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 have a variety of fins or fins that are in the essentially lie in planes running perpendicular to the longitudinal direction of the pipes and are washed around by the oil, to be connected to a pipe fin block which can be 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 the motor and the other end of which can be screwed to the 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 closed off 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 end face of which the seal is arranged.
  • connection piece and the drainage piece for the coolant can finally be equipped with both connection pieces and with a partition be provided between the inlet and outlet connections so that the coolant can flow back into the first water tank only through part of the pipes in one direction and after the deflection in the other water tank through the second part of the pipes.
  • 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 box 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 or 17a, 17b arranged parallel to one another, into which turbulence inserts (not shown) can be inserted, and of lamellar fins 18a, which lie in planes which run perpendicular to the axes of the tubes 11a to 11c and 17a and 17b.
  • These lamellar ribs 18a thus enlarge the heat exchange surface in a known manner. They are solderless with the tubes 11a to 11c or 17a, 17b, e.g. B. connected by expanding the pipes and are in thermal contact with them.
  • the ends of the tubes 11a to 11c or 17a and 17b are inserted in trays 8 and 13, which are inserted into the middle part 2a after inserting the tube fin block 18 from both sides with the interposition of a seal 13a or 8a and then against the middle part 2a jammed. This can be done by widening the free ends of the tubes 11a to 11c or 17a, 17b which protrude beyond the tube sheets 8 and 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 central 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 form cooling liquid collecting spaces 7, 9 and 15 with the bottoms 8 and 13, through which the cooling water supplied through a connecting piece 3 in the direction of arrow 4 can flow out in the direction of arrow 16 to a discharge pipe 5 and from there in the direction of arrow 6.
  • Feed and discharge 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 bottom 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 fixedly connected to the middle part 2a in that an edge 2f of the middle part 2a is flanged around an edge of the water boxes 2d and 2e, so that these against the assigned bases 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 central 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 from the openings 19 in the direction of arrow 23, 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 which is shown in sections, is provided with a bore 34, which is provided with an internal thread at its outer end.
  • a hollow connection piece 28 is screwed through the opening 20 of the oil cooler 1 is inserted.
  • 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 30 b.
  • the oil cooler 1 is sealed by a circumferential seal 31 which bears on the outside of the end face of the edge 30 a.
  • the oil filter 29 has openings 35 through which the oil flowing out of the openings 19 (FIG. 3) in the direction of 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 room 26 b, 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 by the cooling water is flowed through.
  • 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.
