Definitions

  • the DE 197 11 258A1 provides a reinforcing plate between the base plate and the lowermost heat exchanger plate.
  • the uppermost mounting plate has the cutout, and the mounting plates underneath are formed at the openings so that they are suitable for receiving seals.
  • the seal is clamped between a bent opening edge of the one mounting plate and a flat opening edge of the other mounting plate. It is slightly biased and does not fall out of position during assembly. These measures improve the ease of installation of the heat exchanger.
  • Another advantage of the invention over the prior art is also that the material usage is reduced.
  • the Fig. 1 shows the lower portion of the heat exchanger, such as an oil cooler 1. It is trough-shaped from a plurality of nested heat exchanger plates 10. They are located at their outer edges 11 abut each other and form a sealed by soldering heat exchanger. Between the heat exchanger plates 10 are formed by the shape of the heat exchanger plates 10 alternately flow channels 5 for the one and the other medium, which flow through this heat exchanger 1 . In the flow channels 5 , as shown here, turbulence inserts 6 can be provided for a better heat exchange or other possibilities not shown turbulence generation.
  • the media can pass through the openings 21 in the part 3 of the mounting plate and through the inlet and outlet channels 22 and 20 in the heat exchanger 1 or by non-illustrated connection piece.
  • the number of openings 21 in the mounting plate 3 are then adjusted as needed. Their position also depends on the choice of the heat exchanger to be fastened.
  • Fig. 2 the invention is shown.
  • a three-piece mounting plate consisting of the parts 2, 3, 4 is provided.
  • the parts 2 and 3 form at the openings 21 seal receivers as for example in the recently filed patent application DE 10 2006 005 084 are described.
  • Fig. 5 To clamp the seal 41 so that it does not fall out during assembly of the oil cooler 1 , the design of the opening 21 in the part 3 of the mounting plate is wavy here on the one hand and on the other hand, the opening 21 in Part 2 has a special shape 40th
  • the special here is the combination of the advantageous retention of the seal 41 by the particular shape 40 and the reinforcement of the lowermost trumpeterptatte 10 at its edge 11 by the bent edge 25 of the cutout 26 of the part 4 of the mounting plate.
  • the individual parts 2, 3, 4 of the mounting plate can be made of the same thickness sheets or of different thickness sheets. Overall, all mounting plates 2, 3, 4 together in the area below the heat exchanger 1 has a smaller thickness D than described in the prior art and in the remaining area B they are just as thick. However, the parts 2 or 4 of the mounting plate should have a greater thickness than the conventional heat exchanger plates 10 in order to obtain a particularly advantageous reinforcement. It may also be advantageous after bending the edge 25 of the mounting plate 4 in the bend 28 by reworking, z. B. by notching, the concerns of the edge 25 of the cutout 26 of the mounting plate on the edge 11 of the heat exchanger plate 10 to improve.
  • Fig. 3 is shown in the plan view of Part 2 or 4 of the mounting plate.
  • Part 2 or 4 of the mounting plate looks like this after the cutout 26 has been punched out.
  • the corners 52 are provided with an entry or corner cut 50 .
  • a region 51 on which no edge 25 of the cutout 26 at the edge 11 of the lowermost heat exchanger plate 10 is applied (see Fig. 4 ).
  • it is also possible to dispense with the single or corner cutout 50 then a lower material thickness at the corners 52 than at the side edges 53 (not shown).
  • the holes 30 are mounted in all parts 2, 3, 4 of the mounting plate and are used to attach the finished brazed heat exchanger 1 to a motor block or housing.
