Definitions

  • the invention relates to a method for producing the plates for a plate heat exchanger according to the preamble of claim 1 and a plate heat exchanger made from these plates.
  • a plate heat exchanger to which the invention relates consists of a plurality of stacked plates, the mutual spacing of which is determined by projections which are stamped into the plates and protrude from the plate on one or both sides.
  • the projections are arranged in such a pattern that they form parallel flow channels between the plates, these flow channels generally being rotated alternately by 90 degrees between adjacent plates (cross-flow plate heat exchanger).
  • the space between two adjacent plates is open on the narrow sides opposite in the flow direction, so that the medium involved in the heat exchange flows in one direction through every second of the spaces formed by the plates and the other medium perpendicularly through the remaining spaces.
  • the plates for the heat exchanger are made of easily pullable material, into which the protrusions are stamped.
  • an embossing tool which is used to emboss all the protrusions into the plate in a single embossing process.
  • Such a process requires a large and therefore expensive tool and also the availability of a large number of individual tools for different plate sizes.
  • the invention has for its object to develop a method for producing the plates for a plate heat exchanger of the type mentioned, in which the costs for the production of the plates can be kept much lower than in the known methods.
  • a plate heat exchanger which is produced by the method according to the invention has the features mentioned in the characterizing part of claim 7 according to the invention.
  • the method according to the invention makes it possible to produce panels of any size with a relatively small tool. It is sufficient if the length of the tool in the feed direction is so great that it extends only over the pitch T of the pattern of the protrusions in the feed direction plus the pitch t of an adjacent row of protrusions. This can be done perpendicular to the feed direction Tool can be assembled from individual parts according to the width of the plates.
  • Figure 1 shows a plate which is significantly larger than shown in both directions of its plane, which is indicated by the cross-shaped fracture lines a running through the figure.
  • the projections 2a shown in light protrude into the drawing plane, while the projections 2b shown in shaded (dotted) protrude from the drawing plane.
  • the projections lie on a square grid 10, which is constructed from grid fields 11.
  • the projections lying on opposite sides of the grid field are all either concave (grid field lines 10a and 10d) or convex (grid field lines 10c and 10b) with respect to the drawing plane.
  • the horizontal grid lines e.g. 16, 19
  • the vertical grid lines e.g. 36, 39
  • the sheet is pushed through, for example in the direction of arrow A, under an embossing tool 20 (FIG. 2).
  • the division of the pattern of the projections, which is repeated in the feed direction A, is denoted by T. It is therefore equal to the side length of a lattice field 11.
  • the projections are distributed over the sides of a lattice field 11 in such a way that they lie centrally symmetrical to the axis due to the geometric center of gravity of the lattice field.
  • the active i.e.
  • the defining minimum length 20 of the tool in the feed direction has the value W1.
  • n has the value 1, since then the tool has the smallest possible length in the feed direction.
  • the first line 21 and the last line 24 of the tool 20 in the feed direction are equipped with fewer dies (FIG. 2) than a corresponding line of projections 16, 19 on the plate (FIG. 1).
  • the two embossing stamp lines 21 and 24 each have only half as many stamps as there are projections on the corresponding line (grid field line) 19.
  • the embossing dies on one of these two embossing stamp rows are offset relative to the embossing dies on the other embossing stamp row (24) perpendicular to the feed direction.
  • This offset is such that when embossing the two embossing stamp lines 21 and 24 on the same grid field line (in two consecutive embossing processes) a full line 19 of projections is created.
  • the projection lines 16 and 19 are thus produced in two embossing processes and the projection lines 17 and 18 in one embossing process.
  • the finished plate on the outer boundary lines 12 to 15 of the grid is always occupied with such protrusions that are necessary in the finished plate heat exchanger to the edge of the plates support lying flow channels against each other by projections.
  • the number of spacer supports consisting of two cooperating projections is only half as large; in practice, however, this is not a disadvantage. If one were to work with a tool whose embossing length is only equal to a pitch T of the pattern of the projections, then one of the side flow channels would no longer be provided with spacer supports on its outside.
  • FIG. 3 shows, on an enlarged scale, a small section of the plate according to FIG. 1 along the section line I-I.
  • the shape of the two projections 2a and 2b protruding from the plate on one side can be seen.
  • the tool for producing a projection is indicated in principle. It consists of the embossing die 25 and a corresponding die 28 lying on the other side of the plate. It goes without saying that the part of the die on the die side must have a recess at the point 28 indicated by dashed lines in FIG. 2 and the other corresponding points so that the in the first stamping process, the projection stamped by the stamp 28a is not destroyed in the second stamping process.
  • the number of the protrusions lying on the sides 10a to 10b of the grid can also have values other than two. The number can also be odd. With, for example, three projections per grating side, two projections can be arranged on the embossing stamp line 21 and one projection on the embossing stamp line 24, or vice versa.
  • the projections need not have the circularly symmetrical shape according to the exemplary embodiment. They can also have, for example, an elliptical or substantially rectangular shape corresponding to the grid lines.
  • the method according to the invention can also be designed such that the stamp 26a and / or the stamp 27a is missing on the two boundary lines 12a and 13a extending in the feed direction. Accordingly, the projections 26 and / or 27 are then omitted in the finished plate.
  • the plate of a plate heat exchanger constructed from such plates according to the invention then has, for example, a reduced number of projections on all four outer boundary lines 12 to 15.
  • the projections 26 and 27 in FIG. 1 can be dispensed with because they do not provide a supporting function because the corresponding second projection is already missing in the outer boundary lines 14 and 15.
