Definitions

  • Embodiments of the present disclosure relates to a heat transfer plate for a plate heat exchanger and a plate heat exchanger.
  • FIG. 1 shows a typical construction of a plate heat exchanger 100'.
  • the plate heat exchanger 100' comprises a plurality of heat transfer plate 10' stacked on top of each other.
  • the heat transfer plates 10' are formed with patterns such that flow paths are formed between each set of neighbouring heat transfer plates 10'. Openings 21 and 22 are formed in the heat transfer plates 10' to form inlets and outlets for fluids to these flow paths.
  • Gaskets 60 are positioned between the heat transfer plates 10' in gasket grooves 12 formed in the heat transfer plates.
  • the gasket is arranged at an edge portion of the heat transfer plate to seal the flow paths and at an area around the openings to seal pairs of the openings, such that only two of them have flow access to the flow path formed at one side of the heat transfer plate, while the other two is sealed therefrom.
  • FIG. 2 shows that the heat exchanger plates 10' are stacked and positioned between relatively thick and rigid top and bottom plates 51 and 52. Tension shown by arrows is then applied to the heat exchanger plates 10' to keep them close together and to squeeze the gaskets 60 slightly such that stable and fluid tight flow paths are formed. This tension typically is implemented through bolts (not shown) extending from the top plate 51 to the bottom plate 52.
  • the upper figure in FIG. 2 shows the state of the heat exchanger plates 10' before the tension is applied to them, while the lower figure in FIG. 2 shows a frequently experienced problem that this tension tends to prolong the heat exchanger plates 10', such as by several millimetres.
