Abstract: A plate package for a heat exchanger device includes a plurality of heat exchanger plates with mating abutment portions forming a fluid distribution element in every second plate interspace thereby forming in the respective second plate interspaces two arc-shaped flow paths. A respective one of the two flow paths is divided into at least three flow path sectors arranged one after the other along a respective flow path. A plate and a heat exchanger are also disclosed.

Abstract: A heat exchanger plate module comprises a pressed heat exchanger plate and a flat plate, and a heat exchanger comprises plural of the modules. The plates comprise first and second longitudinal end portions each having a fluid port, and an intermediate heat exchange portion between the first and second longitudinal end portions. The plates further include a pressed corrugated pattern with alternating tops and bottoms in the thickness direction. The pressed pattern comprises in the first and/or second longitudinal end portions, a first fluid channel pattern leading fluid flow into the fluid port and/or a second fluid channel pattern bypassing the fluid port. In the intermediate heat exchange portion, a third fluid channel pattern fluidly communicates with the first and/or second fluid channel pattern and comprises longitudinally extending wave-shaped pressed lines that form discrete longitudinal extending fluid channels, when the pressed heat exchanger plate is attached to the flat plate.

Abstract: The disclosure relates to a header connected to or formed as a part of a heat exchanger. The heat exchanger has a heat exchanger body with a plurality of discrete channels for a first fluid and a plurality of discrete channels for a second fluid. The header has a first end having a round configuration and a second end being provided with a plurality of discrete channels. The header is provided with a plurality of dividers dividing one or more internal channels of the circular pipe into the plurality of discrete channels at the second end. At least some of the dividers extend from the second end to the first end and define a plurality of channel mouths at the first end. The disclosure also relates to a heat exchanger.
