  • Such plate heat exchangers are used for exchanging heat between fluids for various purposes.
  • heat exchangers of this type are used for heating or cooling purposes, such as in a heat pump or refrigeration system.

  • Such port opening areas are often flat and arranged to alternatingly contacting each other to provide selective communication with the plate interspaces.
  • the port opening areas are often annular, surrounding the port openings and arranged for selectively sealing against a port opening area of an adjacent heat exchanger plate, for example by a brazing joint.
  • the heat exchanger For some applications, such as in a heat pump application using a refrigerant as one of the fluids, the heat exchanger must be able to withstand relatively high pressures.
  • the port opening areas of brazed plate heat exchangers tend to break if subjected to high pressures.
  • the present invention is related to a brazed plate heat exchanger comprising a stack of at least first and second heat exchanger plates each provided with a pattern comprising ridges and grooves adapted to form contact points between neighbouring heat exchanger plates such that plate pairs of the heat exchanger plates form alternating first and second plate interspaces for first and second fluids to exchange heat over the heat exchanger plates, wherein the heat exchanger plates are provided with port openings forming inlet and outlet channels for the first and second fluids, wherein at least one of the first and second heat exchanger plates in a plate pair is arranged with a skirt extending at least partially around its first port opening to form a chamber between the skirt and plate interspaces, and wherein the chamber communicates with the first or second plate interspaces through a hole in one of the first and second heat exchanger plates of said plate pair, characterised in that the chamber is open to the channel through a gap between at least a free end portion of the skirt and an adjacent heat exchanger plate, and the gap varies along the circumference of the channel and
  • the variation of the gap between the free end portion or the free end of the skirt and the adjacent heat exchanger plate and/or the variation of the cross section area of the chamber result(s) in favourable pressure drop and distribution of the fluid to distribute the pressure and the stress around the port openings and achieve an even and efficient flow of the fluid from an inlet channel and into the plate interspaces.
  • the possibility to control the pressure drop and distribution of fluid into the chamber and further to the hole and hence into the plate interspace result in the possibility to achieve a stronger heat exchanger that can withstand high pressure.
  • the invention provides for a more even flow of the fluid in the inlet channel and improved distribution of the fluid therein, wherein the possibility for the heat exchanger to withstand pressure increases as the pressure on the heat exchanger plates at the skirt is distributed around its circumference to a greater extent.

  • the gap can be smaller closer to the hole and bigger more remote from the hole, so that the fluid is distributed in a more favorable way.
  • the variation of the gap can balance the distribution of fluid in the inlet channel and into the chamber.
  • the cross section of the chamber can be smaller in a position closer to the hole and larger in a position remote from the hole in a direction around the inlet channel to balance the distribution of fluid to the chamber.
  • the volume of the chamber decreases around the inlet channel towards the hole or a section comprising a plurality of holes, e.g., so that the volume of the chamber is smallest between the hole(s) and the portion of the skirt closest to the hole(s).
