Definitions

  • This invention relates to plates for heat transfer apparatus, such as heat exchangers or evaporators.
  • heat is transferred between two thin,. broad streams, which may be both of liquid or one stream of liquid and one stream of vapour or two streams of vapour, or in some cases one or both streams may have mixed liquid and vapour phases.
  • the streams are separated by plates assembled in a spaced face to face relationship to provide flow spaces between the adjacent faces of the plate.
  • the boundaries of the flow spaces are enclosed and sealed byflexible or resilient gaskets surrounding the flow spaces between the flow spaces and entry and exit ports.
  • the ports, in plate heat exchangers usually one at each corner of the plate, are similarly surrounded or part-surrounded by gaskets.
  • a substantially similar construction to that used in plate heat exchangers has also been employed in tissue-culture vessels, which makes advantageous use of the large surface area afforded by such a construction.
  • the gasketing contains a possibly pathogenic organism and in some embodiments is subjected to the thermal shock associated with steam cleaning, it is therefore of the utmost importance that the gaskets sealing ability is not compromised.
  • Each gasket is normally of a one piece construction set within a pressed groove formed in the plate.
  • the manufacture of the gasket is normally carried out in moulds, but according to the size of the plate or the manufacturing techniques used the gasket may be assembled from two or more smaller components.
  • the gaskets are normally moulded of an elastomeric material.
  • the sealing force against the fluid pressure in the flow space is obtained by compression of the gaskets in a direction normal to the plate surface and the resistance to gasket extrusion from the proper sealing position in the groove is normally enhanced by securing the gasket to the plate surface by the application of a system of adhesion, which is necessary in certain applications in order to minimise gasket movement which would result in leakage.
  • a system of adhesion which is necessary in certain applications in order to minimise gasket movement which would result in leakage.
  • Such movements can arise because changes in the loading condition of one gasket will alterthe condition of the gasket on either side, and, perhaps of greater importance, the gaskets are assembled into the groove which is formed from this sheet material and which is therefore flexible.
  • This system of adhesion is frequently complex and time consuming, involving the application of an adhesive to both the gasket and the plate surface, and assembly of the two components together. According to the system which is adopted, it may be necessary to prepare the mating surface of either component before assembly and it may be necessary to subject the assembled components to
  • the gasket should be secured to a surface by fixing means such as a mask, or such as tabs which are attached to or integral with the gasket and are secured to the surface outside of the sealing area.
  • fixing means such as a mask, or such as tabs which are attached to or integral with the gasket and are secured to the surface outside of the sealing area.
  • a further known gasket as best illustrated in the US-A-4 377 204 teaches that the tab should lie in a trough, and be attached by the known oversize projection method related above.
  • a heat transfer plate at least partially bounded by a groove receiving a gasket in general conformity therewith and protruding somewhat thereabove so as to seal against an adjacent similar plate, wherein
  • the means for securing the gasket to the plate comprises an aperture in the plate which co-operates with a stud provided on the gasket.
  • Figure 1 shows an outline of a conventional heat exchanger plate in which the plate 1 has the usual entry and exit ports 2 and the central heat transfer area 3 surrounded by a resilient gasket 4.
  • the gasket 4 As shown in Figure 2, which is a section XX through the gasket (shown dashed), the gasket 4 is mounted in a pressed groove 5 and attached to the plate by means of an oversizxe projection 6, which protrudes through a hole 11, at a fixing point located in a trough 7.
  • the gasket groove 19, as shown in Figure 3 is provided with lateral enlargements in the vertical wall 20 as shown at 11.
  • the width of the gasket groove is locally enlarged. It is proposed that between some or all of these enlargements the groove edge 20 should be formed with a rear wall as indicated by the numeral 27 and as shown in Figure 4, to provide lateral bays 21 in the gasket groove.
  • the lateral bays 21 are provided with apertures 25 and protuberances 10 are provided on the gasket, being manufactured to such dimensions that the protuberances will be slightly compressed when entering the apertures so that the gasket 8 and plate 3 will remain assembled, but can be disassembled by pulling the gasket away from the plate.
  • the wider portions of the gasket groove are normally positioned to alternate one with another from plate to plate, and thus in this embodiment the protuberances 10 remain unaffected by compression when the plate pack is tightened to operable conditions, because the apertures 25 and protuberances 10 are well removed to one side of the sealing surface of the gaskets.
  • apertures 25 are not restricted in their placement to the base of the bay 21 but may be located in such side walls.
  • the bay 30 is not located between two enlargements, but provided in the flat outer wall 31 of a gasket groove 32.
  • An aperture 33a is provided in the base of the bay thereby enabling the gasket to be secured to the heat transfer plate.
  • the bay 30 is rectilinear rather than curvilinear as in the embodiment of figure 3.
  • the gasket may be formed with recesses in the exposed face adapted to seal against the adjacent plate to receive the ends of the projections from the gasket in the groove in that adjacent plate.
