Definitions

  • the invention relates to a heat exchanger, in particular oil cooler, with the features of the preamble of claim 1.
  • Heat exchangers or oil cooler of this type are known, which are constructed of trough-shaped plates.
  • the plates have bent edges.
  • the individual stacked plates are on top of each other like scales.
  • the media are distributed through tubes in the heat exchanger, the plates always alternately forming a channel of one fluid and a channel of the other fluid.
  • the entire oil cooler is by means of a mounting plate on the housing, for. B. on the housing of a filter screwed.
  • a distributor plate is integrated.
  • bores for the coolant, as well as for the oil are arranged, which distribute the two fluids.
  • the distributor plate and the mounting plate can be formed in one piece as well as in two pieces.
  • the oil cooler, the distributor - and the mounting plate are connected together during soldering. To seal the oil cooler relative to the housing grooves are poured into the housing during manufacture, in which then seals are inserted.
  • the housing also contains the connecting pieces for the two fluids.
  • another caseless oil cooler which has a reinforcement plate and a base plate for attachment.
  • the reinforcing plate is configured like a thickened heat transfer plate.
  • base and reinforcement plate are soldered to the oil cooler.
  • the base plate also has a peripheral edge with protruding tabs for tightening the oil cooler on the housing of an engine block.
  • the connecting pieces for oil and coolant are inserted directly into suitable holes in the housing.
  • the oil cooler is sealed off from the housing by means of seals which, on the one hand, are seated on the connecting piece and, on the other hand, are inserted in a groove in the housing.
  • the attachment of the groove in the housing including the creation of a flat sealing surface on the housing can lead to a certain undesirable expense.
  • a heat exchanger which has a base plate and a connection flange fastened thereto for fastening a conduit flange.
  • Another heat exchanger is known comprising a base plate, a reinforcing plate and a mounting plate. This heat exchanger is attached to a central tube.
  • an oil cooler of the type described is known. This oil cooler has a combined base and mounting plate. On the side facing away from the heat exchanger side of the combined base and mounting plate milled recesses are provided for receiving seals. The recesses are annular grooves that surround the openings at a radial distance.
  • FIG. 1 is the entire finished oil cooler 1 to see, with inserted seals 2 before it is screwed by means of the holes 5 on the housing, not shown, or on the engine block.
  • the base 3a and the mounting plate 3b are according to a first embodiment, as shown here, of two different thickness, but preferably with the same outer shape, soldered together plates 3a , 3b exist. Wherein the recesses 10 are to be punched out of the mounting plate 3b for the seals 2 .
  • the plates 3a , 3b can also have the same thickness.
  • the inside 32 which is the side facing away from the engine block side of the mounting plate 3b is solder plated.
  • FIG. 2 An exact plan view of the underside of the mounting plate 3b of the oil cooler 1 shows Fig. 2 , The sections E - E and F - F shown herein can be seen in the following figures.
  • the molded lugs 29 on the outside of the seals 2 serve to pinch the seal 2 , so that they can not fall out during mounting.
  • the recesses 10 for receiving the seals 2 have approximately a bone-like shape. It may also be possible, as in an embodiment not shown, another form, depending on the position of the openings 4 , 6 , which in turn is given by the shape and requirements of the engine block.
  • Fig. 3a and b is the section F - F off Fig. 2 shown.
  • the gasket 2 has noses 29 on the thick, annular bead 28 and is thinned in the middle 27 connecting the two annular beads 28 .
  • the opening 4 , 6 has a smaller cross-section than the recess 10 at the openings 4 , 6 , so that the seal 2 can not be pressed into the oil cooler 1 inside. This achieves a tight connection between oil cooler 1 including soldered base 3a and mounting plate 3b with the engine block.
  • the inside 32 of the mounting plate 3b is solder plated.
  • impressions 20 for a solder deposit in the vicinity of and around the recess 10 are embossed in the fastening plate 3b .
  • These impressions 20 have, as in Fig. 5 Interruptions 34 on, but they could also be consistent.
  • Fig. 3b one sees the soldered oil cooler 1 with the soldered base 3a and mounting plate 3b and with the seal 2 inserted.
  • Fig. 4a and b is the cut E - E off Fig. 2 shown.
  • the recess 10 , 41 in the mounting plate 3b has a larger diameter than the opening 4 in the base plate 3a .
  • Fig. 4b If you see the soldered oil cooler 1 with soldered base 3a and mounting plate 3b and with inserted seal. 2
  • the resulting in the oil cooler 1 by the nesting of the trough-shaped heat transfer plates 9 channels 7 , 8 for the coolant and the oil have been indicated by flow arrows.
  • Fig. 5 is the selected in this embodiment, the bone shape of the recess 10 to see well. It is composed of two circular openings 41 and a 41 connecting the openings slot 42nd
  • the shape of the seal 2 is adapted to the shape of the recess 10 in the respective embodiment.
  • the holes 43 are used for venting during the soldering process.
  • Fig. 6 an alternative embodiment is shown. It shows that the recesses 10 only consist of circular openings 41 without connecting slot 42 . This can be useful depending on the requirement.
  • the recesses 10 are larger than the openings 4 , 6 so that it is ensured here that the seal 2 is not pressed into the oil cooler.
  • the impressions 2 0 for the solder deposit are arranged around the recesses 10 , 41 .
  • the seals 2 also consist of a thick annular bead 28 with molded lugs 29 for clamping the seal 2 , during assembly of the oil cooler 1 on the engine block.
  • the recesses 10 are composed of two circular recesses and a rectangular recess connecting them. This rectangular recess can also be omitted, depending on the requirement.
  • the seals 2 are to be adjusted depending on the case.
