Definitions

  • the present invention relates to a heat exchanger plate for a plate heat exchanger according to the preamble of claim 1 and a method for producing such a plate.
  • a number of profile-embossed thin plates with passage openings lined up form a package of flow gaps through which the heat exchanging media flow reciprocally. Between the plates inserted circumferential seals ensure that the desired flow through the plate pack is achieved and that this is sealed to the outside.
  • the heat exchanger plates used in plate heat exchangers are manufactured from sheet metal by a forming process.
  • austenitic chromium-nickel steels, chromium-nickel-molybdenum steels, nickel-based alloys or titanium are used as the board material.
  • the metal sheets consisting of these materials are manufactured in rolling mills with maximum sheet widths of 1250 mm, in special cases also 1500 mm.
  • the transformation of the metal sheets to heat exchanger plates takes place in special presses, which are limited both in terms of the maximum sheet width and in terms of the achievable pressing force.
  • connections of the plate heat exchangers are arranged side by side.
  • the maximum achievable connection size of piping to a plate heat exchanger directly from the maximum width of the heat exchanger plate determined. This is approx. 450 mm with a sheet width of 1250 mm and approx. 500 mm with a sheet width of 1500 mm.
  • Object of the present invention is to provide a solution that allows the construction of larger plate heat exchanger while maintaining the connection position.
  • the assembly of a heat exchanger plate made of sheet metal segments can be used to Assemble sheet metal segments of different material and / or different wall thickness.
  • So z. Example in heat exchanger plates, which consist of at least three joined together by transverse welds sheet segments, that or the sheet metal segments which form the central region of the heat exchanger plate, are designed with a lower sheet thickness, as the sheet segments that form the two head portions of the heat exchanger plate.
  • the plate thickness of a heat exchanger plate depends on the deformation-technically necessary plate thickness of the head regions, which have the highest local degrees of deformation.
  • the plate heat exchanger 1 shown in Fig. 1 has heat exchanger plates 2, which are mounted in a frame 3 and then clamped by means of clamping screws 4 between two clamping plates 5 and 6, so that the heat exchanger plates 2 are in a package close together. It will be used on each side of the plate heat exchanger 1 two clamping screws 4, of which only one is shown in the drawing.
  • Each heat exchanger plate 2 has four inlet and outlet openings 7 and is profiled in the area between these openings 7. With this profiling, the heat exchanger plates 2 are supported against each other. Furthermore, this profiling provides for an enlargement of the heat exchange surface and for the generation of the heat transfer conducive turbulence of the flow between the plates as well as for a better distribution of the heat exchanging media over the surface of the heat exchanger plate 2. Between the heat exchanger plates 2 inserted circumferential seals 8 provide for a in that the heat-exchanging media can not escape to the outside, but in particular also ensure that the media flows through each second heat exchanger plate pair separated from each other. The inflow and outflow of the heat exchanging media via pipe socket 9, which are provided on the clamping plate 5. The pipe socket 9 are aligned with the inlet and outlet openings 7 of the heat exchanger plates 2.
  • Fig. 2 shows such a composite heat exchanger plate 2 in a schematic plan view.
  • FIG. 3 to 6 show further embodiments of a welded together from sheet metal segments with straight welds heat exchanger plate 2.
  • the heat exchanger plate 2 of four sheet metal segments 12 to 15, by a straight vertical weld 25 and a straight horizontal weld 26th are joined together.
  • the heat exchanger plate 2 is composed of two sheet metal segments 16 and 17, which are interconnected by a straight horizontal weld 26.
  • the heat exchanger plate 2 shown in FIG. 5 is composed of three sheet metal segments 18 to 20, which are joined by two straight horizontal welds 26.
  • the two segments 18 and 20 thereby form the inlet and outlet openings 7 contained head portions of the heat exchanger plate 2.
  • the two sheet metal segments 18 and 20 have a larger wall thickness than the central region of the heat exchanger plate 2 forming sheet segment 19 for technical reasons. You can also made of a different material.
  • the heat exchanger plate 2 shown in Fig. 6 consists of four sheet metal segments 21 to 24, which are connected by straight horizontal welds 26.
  • the central region of the heat exchanger plate 2 is formed here by two sheet metal segments 22 and 23.
  • the individual sheet metal segments 21 to 24 with different wall thickness and / or made of different materials, if they can be welded together.
  • the welds 25, 26 have a course deviating from the straight course. It is expedient if this profile follows the contour of the profiling of the heat exchanger plate 2. But there are also welds 25, 26 possible, the other contours of the heat exchanger plate 2 follow.
  • the heat exchanger plate 2 is composed of two sheet segments 27, 28, in Fig. 8 of two sheet segments 29, 30, in Fig. 9 of four sheet segments 31-34, in Fig. 10 of four sheet segments 35-38 and Fig. 11 of three sheet segments 39-41 together.
  • FIGS. 12-15 show heat exchanger plates 2 with a combination of straight and odd welds 25, 26.
  • the heat exchanger plate 2 is composed of four sheet metal segments 42-45, in FIG. 51, in Fig. 14 of four sheet segments 52-55 and in Fig. 15 of six sheet segments 56-61 together.
  • one or more of the sheet metal segments 27-61 can be manufactured with different wall thickness and / or of different material.
  • the production of one of the sheet metal segments 10 and 11, 12 to 15, 16 and 17, 18 to 20, 21 to 24. 27 and 28, 29 and 30, 31 to 34, 35 to 38, 39 to 41, 42 to 45, 46 to 51, 52 to 55 and 56 to 61 composite heat exchanger plate 2 can be done by two different methods.
  • the sheet metal segments 10 to 61 are first welded together undeformed to form a flat heat exchanger plate blank, which is then converted in total to the finished heat exchanger plate 2.
  • the individual sheet metal segments 10 to 61 are individually formed and then assembled to form the finished heat exchanger plate 2.
  • the last procedure has the advantage that smaller presses can be used.
  • FIGS. 16 to 20 Possible embodiments of the heat exchanger plate 2 in the region of the welds 25 and 26 are shown in FIGS. 16 to 20.
  • the heat exchanger plate 2 in the region of the welds 25 and 26 is designed without profile.
  • the sheet metal segments 10 to 61 are butt welded together, while they are welded together overlapping in the embodiments of FIGS. 17 and 18.
  • two weld seams 25, 26 are provided in the overlapping region, whereby the stability of the heat exchanger plate 2 in this region is increased.
  • the heat exchanger plate 2 is also profiled in the region of the welds 25 and 26. While a butt weld 25, 26 is provided in the embodiment according to FIG. 19, the sheet metal segments 10 to 61 overlap in the profile region. As a result, the profiling of the heat exchanger plate 2 is used for centering the sheet metal segments 10 to 61 prior to welding together. Also in this embodiment is for stabilization in the overlapping area a double seam 25, 26 is provided. Of course, a single seam 25, 26 is possible.
