A heat exchanger plate, where the plate is provided with a heat transfer surface having a corrugated pattern, comprising a diagonal open and closed side distribution support section positioned between a diagonal open respectively closed groove and the heat transfer surface, and a diagonal open and closed side adiabatic support section positioned between the open respectively closed diagonal groove and a port hole, where the heat exchanger plate further comprises a transfer path between the diagonal open side distribution support section and the heat transfer surface and a bypass path between the diagonal closed side distribution support section and the heat transfer surface. A heat exchanger comprising a plurality of heat exchanger plates is also disclosed. The advantage of this heat exchanger plate is that it allows for heat exchangers with an improved efficiency.

Heat exchanger

A device, including a heat exchanger plate and a plate package () of heat exchanger plates () which are provided beside each other to form a plate interspace between adjacent plates. The plate interspaces form, in an alternating order, first passages () for a first medium and second passages () for a second medium which cools the first medium. Each heat exchanger plate has at least two portholes forming a first inlet port channel and a first outlet port channel (), which extend through the plate package to a first inlet and a first outlet, respectively, for the first medium to and from the first passages (). The first outlet forms a gas outlet () for discharging a gaseous portion of the first medium and a liquid outlet () for discharge of liquid of the first medium. The liquid outlet () is separated from the gas outlet () to permit separate discharge of the liquid and gaseous portions.
