Definitions

  • This invention relates to the gasketing of plate heat transfer apparatus.
  • a plate heat transfer apparatus i.e. either a plate heat exchanger or a plate evaporator, consists of a series of plates arranged in a spaced, face-to-face, parallel relationship to form flow spaces between the plates.
  • the boundaries of the flow spaces are formed and sealed by gaskets which are normally mounted in grooves pressed into the plates.
  • the gaskets are normally of a rubber or rubber-like material and are retained in their respective grooves by adhesive.
  • the initial mounting of the gaskets in the grooves is a fairly time consuming process involving surface preparation, application of adhesive, location of the gasket in the groove and probably curing of the adhesive. When the gasket needs to be replaced, the old gasket has to be stripped out, the metal surface cleaned of old adhesive and then the new gasket has to be mounted with all that entails.
  • the gasket recesses were precision machined grooves, the sealing could-be more easily obtained by using preformed 0-ring, lip or other similar seals which would be a close mechanical fit in the grooves and would therefore not need to be retained by adhesive.
  • the usual metal thickness e.g. 0.7 mm
  • precision machining of grooves is not practicable and for many years the use of adhesive has been the normal practice in the industry.
  • the present invention should disclose a replaceable seal and a method of forming a seal which does not require an accurately machined groove in the metal plate, adhesive fixing of the sealing gasket or a specially manufactured sealing gasket.
  • a pressed metal heat transfer plate having a pressed gasket groove characterized in that said pressed groove is at least partially filled with a rigid plastics material which adheres to the plate metal and which is formed in situ with an accurate recess adapted to receive and retain by a close mechanical fit, a preformed seal of O-ring, lip or other appropriate type.
  • the heat transfer plate may be characterised in that the plastics material is formed with two or more accurate recesses to receive seals so as to provide a double or multifold seal between the flow spaces and the environment.
  • the heat transfer plate may be characterised in that the space between the seals of the double seal is monitored for leaking fluid.
  • the heat transfer plate may be characterised in that the monitoring is achieved by circulating a gas or liquid through the space.
  • a method of forming an accurately profiled gasket recess in a pressed metal heat-transfer plate characterised by the steps of forming a pressed groove in the metal plate, at least partially filling the pressed groove with a rigid plastics material which adheres to the metal of the plate, and accurately forming, in situ, the gasket recess in the plastics material.
  • the method may be characterised in that two or more parallel gasket recesses are formed in the plastics material.
  • the method may be characterised in that the or each gasket recess may be formed by moulding or by machining the plastics material.
  • a heat transfer apparatus comprising a pack of heat transfer plates as above defined.
  • a heat exchanger plate is illustrated at 1 and as having four corner ports 2, 3, 4 and 5.
  • the line of a peripheral gasket, of double seal form is indicated at 6, and it will be noted that the corner ports 4 and 5 also have port gaskets 7, also of double seal nature.
  • FIGS 2 to 4 each show a portion of the heat exchanger plate 1 as being provided with a pressed in gasket recess 8.
  • this recess 8 may be converted to a form sufficiently accurate for a preformed seal 6, it is filled with a plastics material 9 which has the property of adhering to the metal of the plate 1 and which is formed, either by pressure moulding or by machining, or a combination of both, with an accurately formed recess 10 to receive the seal.
  • the plastics material can be moulded under pressure so as simultaneously to fix it in the pressed groove and to form a suitably profiled recess 10, for the seal.
  • the plastics material can be roughly sculptured and, when cured, machined to form the final shape of the recess 10.
  • Figure 2 shows a construction in which the filling 9 is formed with a pair of such recesses 10, each of which is shown as receiving an O-ring seal 11 to form the double seal.
  • the configurations of the port gaskets 7 may be similar.
  • a seal of this nature is beneficial, especially if the space between them is monitored for leakage of the hazardous fluid so that this leakage is detected before the hazardous fluid leaks past the second seal into the ambient atmosphere.
  • the space between the two seals 11 may have an appropriate fluid pumped through it and in circuit with a detector to detect the presence of the hazardous fluid in the diluent. Suitable micro-bore piping may be used to make the connections.
  • grooves 10 of Figure 2 are shown as receiving 0-ring seals, lip or other seals could be used instead.
