Definitions

  • the invention refers to a heat exchanger plate for a plate heat exchanger, wherein the plate includes a heat transfer area and a border area, which is located outside the heat transfer area and which extends along and delimits the heat transfer area.
  • the invention also refers to a plate heat exchanger including a plurality of such plates.
  • the invention refers to a method for manufacturing a heat exchanger plate, including the steps of: providing a sheet, cutting and forming the sheet to a heat exchanger plate with a heat transfer area, which has a number of open portholes, and a border area, which is located outside the heat transfer area and which extends along and delimits the heat transfer area,
  • SE-B-548 806 discloses a plate heat exchanger with such heat exchanger plates.
  • the heat exchanger plates are kept together to a plate package by means of tie bolts.
  • Today heat exchanger plates are manufactured by pressing to a desired shape and by cutting for removing unwanted portions, for instance the portholes.
  • the gaskets which are used between the heat exchanger plates in the plated heat exchanger, are manufactured separately, for instance by compression moulding or injection moulding.
  • the gaskets are usually manufactured in any relatively hard rubber material, such as nitrile, EPDM or fluorine rubber.
  • the complete gasket is attached to the complete heat exchanger plate.
  • the gasket is attached to the heat exchanger plate by gluing.
  • the gasket may also include various guide members, for instance so called T-tabs, which extend outwardly from the gasket and which are pressed to attachment in corresponding grooves in the heat exchanger plate.
  • Previous gaskets usually had a substantially rectangular cross-section shape whereas gaskets in recent years have been given a roof-like, acute cross-section shape for the upper surface of the gasket, i.e. the surface which faces and abuts the adjacent heat exchanger plate.
  • DE-A-23 59 978 discloses a plate heat exchanger of another type with plates of glass or any similar silicate material. Between the plates along the edges, strings of a combined sealing and adhesion material including silicon are provided. These strings are arranged successively in such a way that first strings and distance pieces are applied on a first plate. Thereafter, a second plate is applied to the distance pieces and the first strings Second strings and distance pieces are then applied to the second plate, whereupon a third plate is applied to the second strings etcetera. When the plate package has been mounted in this manner, the sealing and adhesion material is cured, whereupon the distance pieces are removed.
  • DE-A-39 05 066 discloses a heat exchanger module with thin metal foils that are stacked on each other with intermediate distance elements including an edge member and a fabric.
  • the edge member includes sealing means, which may consist of different polymer materials such as for instance silicon caoutchouc, thermoplastic resins etcetera.
  • the object is to simplify the manufacturing of plate heat exchangers and remedy the above-mentioned disadvantages.
  • the initially defined heat exchanger plate which is characterised in that a curable polymer material is applied to and cured on the border area in such a way that it extends along the whole or parts of the border area and is arranged to form a gasket for tight abutment against an adjacent plate in the plate heat exchanger.
  • the plate may be manufactured in an easy manner by applying the polymer material in a viscous uncured state to the plate in the border area and thereafter curing the material.
  • a heat exchanger plate on which the polymer material is fixedly attached to the border area and which may be provided adjacent to another such plate in a plate package is obtained.
  • the mounting of the previously used complete gaskets may thus be dispensed with.
  • the manufacturing may in an easy manner be automatised since the viscous polymer material may be applied by means of a robot.
  • the curable polymer material includes silicon, which has good sealing properties. Silicon also has a high adhesion capability to the underlying heat exchanger plate.
  • the curable polymer material may include Liquid Silicon Rubber, LSR.
  • the curable polymer material after curing forms a lower, substantially plane surface, which is attached directly to the border area.
  • the curable polymer material may after curing include an upper surface which in a cross-section has a softly curved, convex shape.
  • a convex shape By such a convex shape, a tight abutment against the adjacent plate is ensured. This abutment will due to the convex shape have an approximately linear shape.
  • the convex shape also contributes to a relatively small risk that the gasket will be attached to the adjacent plate, in particular in comparison with the adhesion to the border area of the underlying plate also after a long time of use.
  • the plate package may thus in an easy manner be dismounted.
  • the curable polymer material includes a first component and a second component, which are mixed to an applicable polymer mixture.
  • Such curable polymer materials may be stored during a long time before the components are mixed.
  • Such curable polymer materials may be given desired properties regarding adhesion capability, viscosity, hardness after curing etcetera.
  • the applicable polymer mixture is before curing highly viscous, wherein the polymer mixture may be applied in an easy manner.
  • the applicable polymer mixture may have a viscosity which amounts to between 300 and 800 Pas (Pascal ⁇ second). By such a viscosity, it may be ensured that the polymer mixture maintains a desired shape before the curing and until the curing is finished.
  • the selected viscosity thus has to be optimised with regard to at least the application capability, shape stability and joint uniformity.
  • the border area includes a bottom surface along substantially the whole border area and at least a first side surface which extends along the whole border area and between the bottom surface and the heat transfer area.
  • the first side surface may be broken in the sense that a break arises where the corrugation of the heat transfer area reaches the first side surface.
  • the first side surface forms an angle to the bottom surface. In such a way a marked path for the polymer material is formed.
  • the border area may also include a second side surface which extends along the whole border area outside the bottom surface, wherein the second side surface forms an angle to the bottom surface.
  • the polymer material will thus be enclosed between the side surfaces and kept in the desired position also after a long time of use of the plate heat exchanger.
  • the heat exchanger plate may also include an edge area, which is located outside the border area and which extends around and delimits the border area, wherein the second side surface extends between the bottom surface and the edge area.
  • the initially defined plate heat exchanger which includes a package of heat exchanger plates of the type defined above.
  • Such heat exchanger plates may in an easy manner be mounted to a plate package of the plate heat exchanger, wherein the plate package is kept together by means of tie bolts or any similar members.
  • the curable polymer material includes a first component and a second component, wherein the method substantially immediately before said application includes the step of mixing the two components to an applicable preferably highly viscous polymer mixture.
  • the first component may include silicon, for instance LSR, and possibly a catalyst, and the second component silicon, for instance LSR, and an activator, for instance in the form of a cross-linking agent, wherein the percentages of the two components in the polymer mixture are substantially equal.
  • the viscosities of the two components are advantageously substantially equal.
  • the curable polymer material may be applied by means of an automatic handling device arranged to carry a nozzle for the discharge of the polymer material and for guiding the nozzle along the border area.
  • the curable polymer material may be cured at a raised temperature, for instance between 150° C. and 250° C.
  • the polymer material may be cured during a curing time which amounts to at least 0,5 h.

  • Such a separation of the interspaces may be obtained by pressing the plates in such a way that the area around the portholes 10 substantially is positioned at a middle plane of the heat exchanger plate 3 .
  • the portholes 10 may also be surrounded by gaskets for obtaining this separation of the interspaces. These gaskets are to be explained more closely below.
