  • US-A-5,918,664 discloses a plate heat exchanger of the kind initially defined, which comprises a plurality of heat exchanger plates. Each of the heat exchanger plates extends in parallel with a main extension plane. The heat exchanger plates are provided beside each other so that they form a plate package having an surrounding edge side and first plate interspaces for a first medium and second plate interspaces for a second medium.
  • Every second heat exchanger plate is formed by a first of said heat exchanger plates and the remaining heat exchanger plates are formed by a second heat exchanger plate in such a way that such a first heat exchanger plate together with such a second heat exchanger plate form a pair of heat exchanger plates, which encloses such a first plate interspace, and that the plate package comprises a plurality of such pairs of heat exchanger plates.
  • Each of the heat exchanger plates has at least two portholes forming ports extending through the plate package and communicating with the first plate interspaces.
  • the heat exchanger plates are configured in such a way that the second plate interspaces are open through the surrounding edge side.
