Definitions

  • the present invention relates to a method for executing the attachment of an inlet or outlet sleeve coupling to a supporting plate of a plate heat exchanger.
  • a plate heat exchanger of this kind is described in more detail in CH-A-633 099 and in Swedish Patent Application No. 8501599-8, from which this Application is derived.
  • a plate heat exchanger comprises a number of preferably rectangular plates, of which the outer plates constitute the aforementioned supporting plates.
  • the number of plates is selected having regard for the capacity of the heat exchanger and is joined together during manufacture, for instance by vacuum soldering.
  • One of the supporting plates is provided with cut-outs for inlet and outlet sleeve couplings.
  • a problem associated with the previously disclosed design is the complex procedure for executing the attachment of the sleeve couplings to the supporting plate.
  • the sleeve coupling is attached to the supporting plate by soldering which is carried out simultaneously with the soldering of the heat exchanger plates.
  • a solder plate is placed between the supporting plate and the sleeve coupling which is held in position by means of a suitable tool.
  • this way of holding the sleeve coupling in position requires skilled handling and a relatively complicated tool otherwise the sleeve coupling may slide during the soldering, which may result in an unsatisfactory connection between the sleeve coupling and the supporting plate.
  • FIG. 1 provides a diagrammatic representation of a plate heat exchanger viewed from above without a supporting plate and sleeve couplings.
  • Fig. 2 illustrates in the form of a cross- section along the line A-A in Fig. 1 a plate heat exchanger with sleeve couplings in accordance with the invention.
  • Fig. 3 illustrates a cross- section along the line B-B in Fig. 1 of the heat exchanger.
  • Fig. 4 illustrates in the form of a detailed view taken from Fig. 3 an attachment of a sleeve coupling in the manner proposed in the invention.
  • the reference 1 is used in the drawing to designate a plate heat exchanger which comprises a number of plates 2a, 2b, 2c and 2d and inlet and outlet sleeve connections 3, 4, 5, 6.
  • the plates 2a, 2b, 2c and 2d are essentially rectangular and have a relief pattern 7 and a border 8 running around its perimeter. This is off-set in two ledges 9, 10 by approximately one thickness of the plate so that the plates 2a, 2b, 2c and 2d are capable of being inserted into one another.
  • This means that the border 8 can be divided up into three steps 8a, 8b, 8c.
  • the first step is so arranged as to enclose the relief pattern 7 of the plate.
  • the second step which is referred to as the screening step, is intended to integrate the flow area for the flow channel of the subsequent plate.
  • the third step 8c is intended to constitute a joining and sealing element with the second step of the adjacent plate and is accordingly described as the joint step.
  • the first ledge shall be situated at a distance from the bend in the border 8 which is approximately equal to the depth of the pattern 7 in the plate 2.
  • the second ledge 10 shall be situated at a distance from the bend in the border 8 which is approximately equal to twice the depth of the pattern.
  • the inlet and outlet sleeve couplings are designated respectively by 3 and 6 and are attached to the supporting plate 11 a by the aforementioned sleeve couplings 3, 6, on the side which it is intended to attach to the supporting plate, being provided with a section 14 of thinner wall thickness than the rest of the sleeve coupling.
  • This section is illustrated in Fig. 4 by a solid line and is shown to be introduced into a cut-out intended for this purpose in the supporting plate. The outer end of the section with thinner wall thickness is then formed around the edge of the cut-out executed in the supporting plate so as to produce a flange 14a.
  • a first fixing between the supporting plate and the sleeve coupling is achieved in this way.
  • the plates of the heat exchanger are manufactured from a material which consists of, for example, stainless steel sheet with a thin layer of copper applied to it by rolling.
  • the copper layer forms a solder on soldering and also produces a good soldered joint between the supporting plates and the sleeve couplings.
