Definitions

  • German patent application DE 10 2004 003 790 A1 discloses a heat exchanger/oil cooler with a relatively thick base plate which is hollowed out in a trough shape in complex processing steps. The heat exchanger is inserted into this hollow shape, and then soldered to the base plate. This measure serves to avoid fractures in edge regions of the bottom heat exchanger plate due to thermal and mechanical stresses.
  • Japanese patent application JP 02-691155 discloses various options for strengthening the bottom plate of a heat exchanger.
  • a stable base plate such as that described above
  • strips are applied from the outside, and extend on the base plate and around the circumference of the bottom heat exchanger plate.
  • Some embodiments of the present invention provide alternative, manufacturing-friendly solutions for heat exchangers having lower heat exchanger plates resistant to thermal and mechanical stresses.
  • a multipart heat exchanger attachment plate wherein a bottom heat exchanger plate lies on an attachment plate and an attachment plate which is arranged above it has a cutout having an edge shaped to lie against the trough-shaped edge of the bottom heat exchanger plate.
  • the edge of the cutout has a bending angle which corresponds to the angle of the trough-shaped edge of the bottom heat exchanger plate.
  • the angle of the trough-shaped edge can be approximately 8 to 15°.
  • the bending angle of the edge of the cutout can therefore exceed 90°, and in some embodiments is approximately 98 to 105°.
  • the shaping of the edge can be made easier if the corners of the cutout are indented or cut out.
  • the attachment plate is embodied in three parts. In light of the design feature disclosed herein, it is possible to provide an attachment plate having an overall thickness no greater than that found in the prior art. Nevertheless, the thickness of each part of the attachment plate can be significantly greater than the thickness of the heat exchanger plates.
  • the top attachment plate can have the cutout, and the attachment plates which are arranged below it can be formed in such a way that they are suitable for receiving seals.
  • Parts of the attachment plates can have marks so that they can be assembled more easily. Parts of the attachment plates can also have matching holes in order to be able to mount the heat exchanger.
  • a seal is clamped between a bent-over opening edge of one attachment plate and a planar opening edge of another attachment plate.
  • the seal can be placed under a degree of pre-stress so that the seal does not drop out of its position in the course of mounting.
  • the cutout is smaller than the base surface of the heat exchanger plate before the shaping of the edge is carried out.
  • the cutout and the base surface of the heat exchanger can, for example, be embodied as rectangles, with the four sides of the edge of the cutout running parallel to the four sides of the base surface.
  • FIGS. 1-5 Various features of the present invention are described with reference to exemplary embodiments shown in FIGS. 1-5 , wherein:
  • FIG. 1 shows a section through the lower region of a heat exchanger
  • FIG. 2 shows a partial section through a heat exchanger of another exemplary embodiment
  • FIG. 3 shows a plan view of an attachment plate used in FIGS. 1 or 2 ;
  • FIG. 4 shows another a plan view of the attachment plate of FIG. 3 ;
  • FIG. 5 shows a view of the attachment plate opening shown in FIG. 2 , viewed in the direction of the arrow in FIG. 2 .
  • FIG. 1 shows a lower region of a heat exchanger 1 , which is presented by way of example only as an oil cooler.
  • the illustrated heat exchanger 1 is composed of a number of trough-shaped heat exchanger plates 10 which are stacked one inside the other.
  • the heat exchanger plates 10 bear against one another at their outer edges 11 to form the heat exchanger 1 , which is sealed by soldering or brazing.
  • Alternating flow ducts 5 for two mediums flowing through the heat exchanger 1 are defined between the heat exchanger plates 10 , which are shaped to define the flow ducts 5 .
  • In the flow ducts 5 it is possible, as is shown here, to provide turbulence inserts 6 for improved heat exchange, or to provide other elements or structure (not shown) for generating turbulence.
  • media passes through the openings 21 in a part 3 of an attachment plate, and flows into and out of the heat exchanger 1 through feed ducts 22 and discharge ducts 20 (see arrows in FIG. 1 ).
  • the media can also flow into and out of the heat exchanger 1 through connectors (not shown) so that four openings 21 are provided in the part 3 of the attachment plate if both media are conducted through the attachment plate 3 .
  • the number and positions of openings 21 in the attachment plate 3 are adapted according to requirements of the heat exchanger.
  • a cutout 26 is punched into an attachment plate 2 during its manufacture, and the edge 25 of the cutout 26 is bent over subsequently or simultaneously.
  • the edge 25 of the cutout 26 can be bent in such a way that its end 27 covers to a greater or lesser extent approximately half of the edge 11 of the bottom-most heat exchanger plate 10 , and bears directly against it.
  • a bending radius for the edge 25 of approximately 98 to 105° can be produced, since the edge 11 of each heat exchanger plate 10 is bent outward away from a vertical orientation by approximately 8 to 15°.
  • This reinforcement configuration at the bottom-most heat exchanger plate 10 can avoid stress fractures. At the same time, in this way it is possible to reduce the consumption of material without reducing the ability of the heat exchanger and heat exchanger mounting structure to withstand stress. In fact, the ability to withstand such stress can even be improved which achieving this material savings.
  • FIG. 2 shows another exemplary embodiment of the heat exchanger 1 .
  • a three-part attachment plate is used, and includes parts 2 , 3 , and 4 .
  • Parts 2 and 3 can define seal receptacles at the openings 21 , such as are described, for example, in patent application number DE 10 2006 005 084).
  • the opening 21 in the part 3 of the attachment plate can be, on the one hand, formed here in a corrugated shape, and on the other hand the opening 21 in the part 2 can be shaped to at least partially receive the seal 41 (e.g., by a nested relationship with the seal 41 and/or by a rolled shape 40 in which the seal 41 is received).
  • significant advantage can be obtained through the combination of the secured or retained seal 41 (e.g., by means of the particular shape 40 of the attachment plate) and reinforcement of the edge 11 of the bottom-most heat exchanger plate 10 by the bent-over edge 25 of the cutout 26 of the attachment plate part 4 .
  • the individual parts 2 , 3 , 4 of the attachment plate can be manufactured from sheet metal plates of equal thickness or from sheet metal plates of different thicknesses. Overall, all the attachment plates 2 , 3 , 4 together can have a smaller thickness D in the region underneath the heat exchanger 1 compared to structures in the prior art, and in the rest of the region B can be equally thick (if desired).
  • the parts 2 or 4 of the attachment plate can have a greater thickness than conventional heat exchanger plates in order to bring about particularly advantageous reinforcement. After bending over the edge 25 of the attachment plate 4 , it may also be advantageous to improve the bearing of the edge 25 of the attachment plate cutout 26 against the edge 11 of the heat exchanger plate 10 in the bend 28 by post-processing, such as by notching or other operations.
  • FIG. 3 shows a plan view of the part 2 or 4 of either attachment plate shown in FIGS. 1 and 2 .
  • Part 2 or 4 of the attachment plate can have the appearance shown in FIG. 3 after the cutout 26 has been punched or made in any other manner.
  • the corners 52 can each be provided with an indent, notch, cut, or corner cutout 50 (collectively referred to herein as a “cutout”).
  • a region 51 can be produced at the corners 52 of the cutout 26 , at which region 51 an edge 25 of the cutout 26 does not bear on the edge 11 of the bottom heat exchanger plate 10 (see FIG. 4 ).
  • Holes 30 can be formed in all the parts 2 , 3 , 4 of the attachment plate to serve as engine block or housing attachment locations for the completely soldered heat exchanger 1 .
  • all the parts 2 , 3 , 4 of the attachment plate have marks in order to facilitate the mounting process.
