    摘要： The disclosure relates to a plate heat exchanger (1) comprising: a package of heat exchanger plates (2), each having a peripheral portion (4) and several port portions (6a,6b) with through flow ports (8a,8b) communicating with flow passages (12) between adjacent heat exchanger plates (2). First guiding ribs (50) are arranged in the port portions (6a,6b), which first guiding ribs (50) in every other flow passage (12) between the heat exchanger plates (2) are configured to guide and distribute the first heat exchange medium (18) from a first inlet channel (16a) to a heat exchange portion (14) and from the heat exchange portion (14) to a first outlet channel (16b), and in that second guiding ribs (52) are arranged in the port portions (6a,6b), which second guiding ribs (52) in the remaining flow passages (12) between the heat exchanger plates (2) are configured to guide and distribute a second heat exchange medium (22) from a second inlet channel (20a) to the heat exchange portion (14) and from the heat exchange portion (14) to a second outlet channel (20b).

    摘要： The disclosure relates to a heat exchanger (100) comprising a stack of heat exchanger plates (102), a first set of channels (302), and a second set of channels (304), in each of the channels in the first and second set of channels (302, 304) fin structures (210) are positioned between the heat exchanger plates (202), in a first channel of the first set of channels (302), a first fin structure (210a) comprises at least a first and a second part (210a1-2), in a first channel of the second set of channels (304), the first channel of the second set of channels (304) being a neighbouring channel to the first channel of the first set of channels (302), a second fin structure (210b) comprises at least a first and a second part (210b1-2), an interface between the first and second parts (210a1-2) of the first fin structure (210a) extends across the fin direction (FD) and is positioned at a first position (P1), an interface between the first and second parts (210b1-2) of the second fin structure (210b) extends across the fin direction (FD) and is positioned at a second position (P2), and the first and second position are separated a distance (DP) from each other.

    摘要： The disclosure relates to a plate heat exchanger (1) comprising: a package of heat exchanger plates (2), each having a peripheral portion (4) and several port portions (6a,6b) with through flow ports (8a,8b); wherein the heat exchanger plates (2) are permanently joined to adjacent heat exchanger plates (2) of the package along their peripheral portions (4) in such manner that they leave flow passages (12) in a heat exchange portion (14) between adjacent heat exchanger plates (2). The through flow ports (8a,8b) of the heat exchanger plates (2) are aligned and form first inlet and outlet channels (16a,16b) through the package for a first heat exchange medium (18), which communicate with every other flow passage (12) between the heat exchanger plates (2), and second inlet and outlet channels (20a,20b) through the package for a second heat exchange medium (22), which communicate with remaining flow passages (12) between the heat exchanger plates (2). Fins (32) are arranged in the heat exchange portion (14) of the flow passages (12) between the adjacent heat exchanger plates (2), which fins (32) creates a number of parallel guide channels (34) for each of the first and second heat exchange medium (18,22), respective.
