  • the desired distance of the adjacent plates can be to each other.
  • that diametrically opposite breakthroughs of the plates are the same size are, preferably in superimposed plates an upper Breakthrough designed to double the material thickness is greater than a lower breakthrough.
  • the openings each surrounded by a peripheral bead This can be done very advantageous the plates for training against each other sealed Insert flow paths pressure-tight. Due to the circumferential beads is a minimum Gap geometry between adjacent plates obtained in easy to seal pressure-tight.
  • Figure 1 shows a plan view of a generally designated 10 Heat exchanger.

  • cover plate to be explained later and connection plate not marked.
  • the heat exchanger 10 consists of plates 12 stacked on one another. According to the embodiment shown, four plates 12 are provided, it being understood that the number of plates 12 corresponds to the number of plates Requirements for the heat exchanger 10 may be smaller or larger.
  • the structure of the plates 12 is based on the plan view in Figure 1 on the upper plate 12 of the heat exchanger 10 explained.
  • the plate 12 is in Essentially disc-shaped and has a bottom 14, the is encompassed by a bevelled edge 16. This creates a, in the sectional views clearly becoming cup-shaped shape of the plates 12th
  • the base 14 forms a heat transfer area 18, which differs from Areas 20, 22, 24 and 26 is encompassed.
  • the areas 20, 22, 24 and 26 are arranged in a clockwise direction around the heat transfer area 18 and thus border on the one hand via inner edges 28 to the heat transfer area 18 and outer edges 30 to the edge 16 at. to better clarification of the still to be explained construction of the plates
  • the areas 20 and 24 associated inner edges with 28 and Outside edges with 30 and the areas 22 and 26 associated inner edges denoted by 28 'and the outer edges with 30'.
  • the heat transfer area 18 coincides with the plane of the bottom 14 of FIG Plate 12 together. According to the drawing in Figure 1 is Assume that the heat transfer area 18 in the paper plane lies.
  • the opposite regions 20 and 24 are formed in such a way that this below the level of the heat transfer area 18th lie while the opposing portions 22 and 26 formed in such a way These are above the level of the heat transfer area 18 lie.
  • the inner edges 28, 28 'thus form a kind of step, over which the areas 20, 22, 24, 26 in the heat transfer area 18th pass. As the sectional views make clear, the inner edges 28, 28 'in this case substantially not perpendicular to the plane of Heat transfer region 18 is formed.
  • the area 24 has a Breakthrough 34, while the area 20 has a breakthrough 32.
  • the region 26 has a breakthrough 36 and the region 22 a breakthrough 38.
  • the apertures 32, 34, 36 and 38 have an im Essentially oval shape, on each of the heat transfer area 18 facing side is flattened.
  • the breakthroughs 32 and 34 have the same size and the apertures 36 and 38 also have the same size.
  • the openings 32 and 34 are larger than the openings 36 and 38 and that according to a double Material thickness of the plate 12 is formed. This point of view becomes With reference to Figure 4 in more detail.
