Definitions

  • the invention relates to a heat exchanger, in particular an oil cooler, with the features of the preamble of claim 1.
  • An oil cooler is out DE 103 47 181 A1 known. At the oil cooler shown there, the seals are pressed by noses formed thereon into the seal receptacle of the two-part mounting plate. Such seals are custom-made and therefore expensive.
  • the object of the present invention is to further improve the handling of the heat exchanger during assembly to a housing and to allow the use of ordinary O-ring seals.
  • EP 0 801 283 A1 shows a solution where the end plate is solid, and provided with a groove for the insertion of the O-ring seal.
  • the seals are fixed in place by the shaping of the edges, which extend around the openings of the at least two mounting plates. This has the effect that a simple O - ring can be used as the seal, which remains in place, thus simplifying the assembly of the oil cooler.
  • a further development aspect provides that the shaping of the edge of the openings of the one fastening plate is formed with projections.
  • a wave-shaped contour can be provided with wave crests and troughs.
  • the shape of the edge of the opening of the other mounting plate has a collar-like contour which engages in the opening of a mounting plate. Therefore, a groove is formed between the two edges of the openings, in which the seal is clamped.
  • Fig. 1 is a section of the oil cooler 1 can be seen.
  • the oil cooler 1 itself is not shown in detail. It is constructed of stacked trough-shaped heat exchanger plates. There are alternating flow channels for oil and coolant between the heat exchanger plates. About the inlet and outlet channels, the media are supplied to the flow channels and discharged therefrom.
  • mounting plates 2 and 3 Shown is a two-part mounting plate 2, 3, with which the oil cooler is attached to a housing, for example on an engine block. Depending on requirements, the mounting plate can also consist of more than two parts. (see section A in Fig. 3 where a line indicates that, for example, the mounting plate 3 may consist of several plates).
  • the individual mounting plates may have the same thickness or be configured differently thick.
  • 2 cutouts 30 are provided in the mounting plate, which serve to absorb excess solder and to avoid air pockets in the solder joint.
  • the mounting plates 2, 3 there are a plurality of openings 21 through which a medium, for example the oil, enters or exits the cooler.
  • a medium for example the oil
  • connecting pieces 5 are for the other medium.
  • the second medium can also be fed in and out through the attachment plates 2, 3 .
  • there are at least four openings 21 each with a seal 20.
  • the seal 20 is a common O-ring used for such purposes with a uniform diameter d.
  • the Fig. 3 shows in detail the detail from the Fig. 1 in which the opening 21 can be seen.
  • the fixation of the seal 20 around the opening 21 is achieved by the shape of the bent edge 22 of the opening 21a of the mounting plate 2 and the wave-shaped design of the edge 25 of the opening 21b of the mounting plate. 3
  • the openings 21a and 21b are punched out of the attachment plates 2, 3 during their production.
  • the opening 21 a in the mounting plate 2 is smaller than the opening 21 b in the mounting plate 3, since after or at the same time as the punching, the edge 22 of the opening 21 a is bent down to the Seal 20 to fix.
  • the edge 22 has a collar-like contour, wherein ideally the edge 22 is bent by about 90 ° relative to the plane of the mounting plate 2 .
  • the upper end of the collar has a bending radius, so that this area is funnel-shaped. At the lower end of the bent edge 22 is straight around. However, it could also have a wave-like course.
  • the edge 22 is bent so far down that the seal 20 is held well. The edge should not protrude beyond the mounting plate 3 . If that were the case, the seal 20 could no longer be clamped between the oil cooler 1 and the housing and the oil cooler 1 would no longer be tightly connected to the housing.
  • the bent edge 22 of the opening 21a engages in the opening 21b .
  • the opening 21b in the mounting plate 3 must be larger, otherwise the seal 20 between the edge 22 and the wavy edge 25 of the opening 21b in the groove 28 has no place.
  • the wave-shaped edge 25 of the opening 21b has a plurality of wave crests 26 and wave troughs 27.
  • the wave crests 26 the seal 20 is pressed against the bent edge 22 of the opening 21a .
  • the diameter D between the two edges 22 and 25 of the openings 21a and 21b of the two attachment plates 2 and 3 is smaller than the diameter d of the seal 20.
  • the troughs 27 serve to secure the attachment Oil cooler 1 to the housing of the seal 20 to provide space. There, therefore, the 26 pressed away from the wave crests sealing material can spread.
