Definitions

  • the invention relates to a plate heat exchanger, consisting of a plurality of stacked trough-shaped heat exchanger plates with a stepped, circumferential, outer edge, the edges being joined by joining, in particular soldered.
  • Plate heat exchangers of this type are known for example from EP 0250439 and 0258236.
  • the plate heat exchangers are composed of individual trough-shaped heat exchanger plates of different designs, in particular different edge designs. Such heat exchanger plates are produced by suitable forming processes, for example deep drawing.
  • the stack is designed so that the heat exchanger plates with a single step edge design alternate with those with a double step edge design.
  • the heat exchanger plates also differ in their other design in such a way that they are suitable for being stacked on top of one another and connected in terms of joining technology to form separate flow channels through which the heat-exchanging fluids can flow.
  • edge design is unsatisfactory for a quality soldering process. As it cannot guarantee sufficient rigidity of the heat exchanger plates, the positioning and fixing of the plates stacked one inside the other will often be incorrect.
  • the object of the invention is to further develop a plate heat exchanger of the type described in the introduction in such a way that its manufacture becomes simpler and in particular enables a higher quality of the soldering process.
  • the pressing force is only transmitted vertically via the horizontal gradation and the vertical edge, so that the heat exchanger plates cannot slip even during the soldering process, but rather retain their desired position.
  • connection surface main connection surface
  • pressure soldering can take the place of gap soldering.
  • connection area leads to an effective enlargement of this area and makes an additional contribution to the quality-appropriate soldering.
  • the channel-like depression in the bottom of the heat exchanger plates improves the sharpest possible design of the rectangular outer edge. This is also a contribution to the correct positioning and to increase the connection area. Due to the material shift occurring in this area, the rigidity of the heat exchanger plates is further increased and cracking is inhibited.
  • An additional effect of the channel-like depression that is particularly worth mentioning is that the vertical force F is concentrated on the edge region or the main connecting surface, because the fins usually arranged between the heat exchanger plates are pressed into the channel-like circumferential depression and consequently reduce their resistance to the force F. .
  • the functionally unimportant outer radii in the area of the horizontal gradation have been chosen to be relatively large in order to counteract the risk of cracking.
  • the invention provides heat exchanger plates with a uniformly graduated edge design, which lead to advantages in terms of production technology.
  • the feature of claim 8 brings about a more stable design against mechanical influences, for example stone chipping, which occurs relatively frequently when the plate heat exchanger according to the invention is installed in motor vehicles.
  • Claims 11 to 14 additionally lead to a lower overall height of the heat exchanger and to a lower use of materials. Furthermore, the arrangement of the horizontal gradation at different heights, in conjunction with the turbulence-generating elevations impressed in the base of the heat exchanger plates, allows the plate heat exchanger to be better adapted to different cooling performance parameters. In known plate heat exchangers, in which the individual heat exchanger plates are always arranged with the same vertical distances, the cooling capacity can be varied by the number of heat exchanger plates, by measures improving the heat transfer, etc. The invention here provides an additional possibility of adapting the cooling capacity.
  • the water side of the heat exchanger is preferably formed with the lower vertical distance.
  • all of the heat exchanger plates are alternatively formed in their base with turbulence-generating elevations, which can be provided in different numbers, shape, arrangement and overall height.
  • the height extension within a heat exchanger plate should be the same.
  • the plate heat exchanger 1 is made of aluminum sheet. It serves to exchange heat between oil and water.
  • the outer shape of the plate heat exchanger 1 can be any, that is, it is adapted to the particular application and the installation location.
  • the plate heat exchanger 1 consists of six heat exchanger plates 2, which are stacked one inside the other and acted upon by a vertical force F, which is generated by the weight of a metal block placed thereon. Between the heat exchanger plates 2 fins 13 are arranged, which serve to improve the heat transfer. For a quality-appropriate soldering of all parts of the plate heat exchanger 1, as shown in FIG. 1, the exertion of a force F on the stack and in particular on the edge area is of great importance.
  • the lamellae 13 are pressed into the channel-like recess 6 worked into the bottom 5 in the edge region. You thus get the possibility to avoid, which leads to the fact that the force F is concentrated on the horizontal main connecting surface 3.
  • the main connection surface 3 between the heat exchanger plates 2 is formed by the lower edge of the respective upper heat exchanger plate 2a and the horizontal step 4 in the edge of the heat exchanger plate 2b located below it. Pressure soldering is possible on this surface 3, which guarantees a better quality of the soldered connection.
  • the main connection surface 3 is through the vertical connection surface located between the legs 12 has been expanded or enlarged, in which the solder runs and ensures an additional seal.
  • Each heat exchanger plate 2 has the same edge formation, as can be seen particularly from FIGS. 1 and 2.
  • 2 shows further important details. 2 mm were determined and provided as a favorable dimension for the width b of the circumferential channel-like depression 6.
  • the outer radius 7 of the lower outer edge 8 could be minimized, which has a positive effect on the enlargement of the main connection area 3.
  • the horizontal gradation 4 produced by material displacement has a sharp edge 41 on the inside and a rounding 42 with a correspondingly large radius on the outside.
  • the edge design also has a kink to the outside at a distance from the horizontal gradation 4.
  • FIG. 3 shows a further gradation 10 of the edge with a vertical edge termination 11.
  • all of the designs already mentioned, such as channel-like depression 6, horizontal gradation 4 with the inner edge 41 and the rounding 42, can be seen from this figure.
  • FIG. 4 shows a plate heat exchanger 1 which is already connected to a finished block by brazing.
  • the lamellae 13 usually present in the flow channels 14 were not drawn.
  • the separation of the flow channels 14 for, for example, oil and water has been ensured in this embodiment in that the neckings for the inflow and outflow of the fluids are each formed opposite to a horizontal plane.
  • the flow channels 14 thus sealed against one another then, viewed in the vertical direction, alternately lead e.g. Oil or water.
  • FIG 5 shows the area of the heat exchanger 1 with the coolant inlet side (water).
  • the water flows through the plate heat exchanger 1 according to the arrows 15 shown.
  • the flow channels 16, 17 have different cross-sectional areas.
  • the flow channel 17 for the water side has a lower height h than the flow channel 16 for the oil side.
  • Turbulence-generating knobs 18 are worked into the bottom 5 of the heat exchanger plates 2b and the water flows around them.
  • the upper end 19 of each knob 18 is soldered to the bottom 5 of the heat exchanger plate 2 a arranged above, whereby the compactness and resistance to internal pressure has been significantly improved.
  • the vertical height h of the knobs 18 is identical to the arrangement height of the horizontal step 4 in the vertically erected edge 20.
  • the flow channel 16 for the oil side is the one with the greater height H, this height H also being equal to the arrangement height of the horizontal step 4 in the vertical direction circumferential edge 20 of the heat exchanger plate 2a.
  • each heat exchanger plate 2a; 2b also has a relatively sharp-edged lower edge 21 and channel-like recess 6 embossed in the base 5 as a circumferential groove 22.
  • the horizontal step 4 is provided in two different heights H; h in each heat exchanger plate 2a; 2b.
  • the flow paths for water and oil in the flow channels 16; 17 are illustrated by the arrows 15; 24 of FIG. 6.
  • the flatter flow channels 17 on the water side have also been equipped with knobs 18 stamped into the bottom 5.
  • the larger flow channels 16 on the oil side accommodate fins 13.
  • the upper end of the plate heat exchanger 1 is formed by a cover plate 25, which could alternatively be equipped to accommodate the connections for the media.
  • the structural structure of the plate heat exchanger 1 can best be seen from the exploded view in FIG. 7.
  • the housing-free plate heat exchanger 1 has a base plate 26 at the bottom, which serves to fasten the plate heat exchanger 1, for example in a motor vehicle, and at the same time accommodates the connecting flanges (not shown) for the media.
  • the plate heat exchanger 1 implemented in practice will consist of a plurality of these elements, which are arranged as described, depending on the cooling capacity required. The plate provided between the upper heat exchanger plate 2b and the cover plate 25 was not drawn.
  • FIG. 8 An alternative embodiment is shown in FIG. 8.
  • oil-side fins 13 were dispensed with.
  • turbulence-generating and distance-forming elevations knocks 18
  • This embodiment leads to lower manufacturing costs, fewer individual parts and results in lower pressure losses. In terms of performance, a compromise was achieved that is of interest for certain applications.
