  • the present invention relates to a plate heat exchanger.
  • the invention relates to collars of the plate heat exchanger which promote laminar fluid flow within the heat exchanger.
  • a plate-type heat exchangers may include a plurality of plates stacked together to form two fluid channels.
  • the two fluid channels are fluidically isolated from each other, yet thermal coupled with each other.
  • adjacent plates of the stacked plates delimit the path for the fluid channels.
  • Each plate may include openings for enabling fluid flow into the respective fluid channels.
  • the openings provided in the stack of plates form conduits that transfers the fluid to the respective fluid channels. Further, the openings may include collars to fluidically connect the conduits with the respective fluid channels.
  • the two fluid channels can be a refrigerant channel and a coolant channel.
  • the collars may include a portion that protrudes from the plates in a direction parallel to the longitudinal axis of the plates.
  • Such portion in the collars may cause detrimental change in fluid path between the conduit and the fluid channels.
  • the fluid flowing between the conduit and the respective fluid channel may have detrimental change in its flow path, i.e., 90 0 change in fluid flow direction.
  • Such change in direction flow between the conduits and the fluid channels may leads to high pressure drop of the fluid at an inlet area in the conduits.
  • Such highpressure drop of the fluid may cause non-uniform fluid distribution in the fluid channels that leads to inefficient heat exchange between two fluid flowing in the heat exchanger.
  • some elements or parameters may be indexed, such as a first element and a second element.
  • this indexation is only meant to differentiate and name elements, which are similar but not identical. No idea of priority should be inferred from such indexation, as these terms may be switched without betraying the invention. Additionally, this indexation does not imply any order in mounting or use of the elements of the invention.
