Abstract
A plate heat exchanger comprises at least one unit comprising four plates, namely a plate pack comprising a first plate having transversely extending cutouts therein and an adjacent second plate having transversely extending cutouts therein, the plate pack being sandwiched between two solid plates without cutouts. At least some of the cutouts of the first plate intersect at least some of the cutouts of the second plate.

A plate heat exchanger, wherein the plate heat exchanger is configured for enabling a heat exchange between two media and comprises at least a first unit comprising four rectangular plates of identical outer dimensions, namely a plate pack comprising a first plate having non-intersecting cutouts therein and an adjacent second plate having non-intersecting cutouts therein, the plate pack being sandwiched between two plates without cutouts, individual cutouts of the first and second plates extending transversely from a vicinity of an edge at one side of the first or second plate towards a vicinity of an edge at an opposite side of the plate and belonging to one of two groups of cutouts, namely a first group of cutouts which are closed at both ends thereof in the vicinities of the edges at opposite sides of the plate, and a second group of cutouts which are closed at one end thereof in a vicinity of an edge at one side of the plate from which they extend, an end opposite to the closed end of the cutout terminating in one of the edges of the plate which are perpendicular to the edges of the plate from whose vicinities the cutouts originate, thereby forming gaps in the perpendicular edges, and wherein the two plates with intersecting cutouts are identical or differ with respect to at least one of thickness of the plate, number of the cutouts, width of the cutouts, distance between the cutouts, configuration of the cutouts, and inclination of the cutouts, and wherein one of the first and second plates with cutouts is rotated from a parallel orientation by 180° around its central symmetry axis that is parallel to the edges of the sides of the plate in whose vicinity the cutouts originate, resulting in at least some of the cutouts of the first plate intersecting at least some of the cutouts of the second plate.
A unit which is suitable for use in a plate heat exchanger, wherein the unit comprises four rectangular plates of identical outer dimensions, namely a plate pack of a first plate having non-intersecting cutouts therein and an adjacent second plate having non-intersecting cutouts therein, the plate pack being sandwiched between two plates without cutouts, individual cutouts of the first and second plates extending transversely from a vicinity of an edge at one side of the first or second plate towards a vicinity of an edge at an opposite side of the plate and belonging to one of two groups of cutouts, namely a first group of cutouts which are closed at both ends thereof in the vicinities of the edges at opposite sides of the plate, and a second group of cutouts which are closed at one end thereof in a vicinity of an edge at one side of the plate from which they extend, an end opposite to the closed end of the cutout terminating in one of the edges of the plate which are perpendicular to the edges of the plate from whose vicinities the cutouts originate, thereby forming gaps in the perpendicular edges, and wherein the two plates of the plate pack are identical or differ with respect to at least one of thickness of the plate, number of the cutouts, width of the cutouts, distance between the cutouts, configuration of the cutouts, and inclination of the cutouts, and wherein one of the first and second plates with cutouts is rotated from a parallel orientation by 180° around its central symmetry axis which is parallel to the edges of the sides of the plate in whose vicinity the cutouts originate, resulting in at least some of the cutouts of the first plate intersecting at least some of the cutouts of the second plate.
A plate pack which is suitable for use in a plate heat exchanger, wherein the plate pack comprises a first rectangular plate having non-intersecting cutouts therein and an adjacent second rectangular plate having non-intersecting cutouts therein, individual cutouts of the first and second plates extending transversely from a vicinity of an edge at one side of the first or second plate towards a vicinity of an edge at an opposite side of the plate and belonging to one of two groups of cutouts, namely a first group of cutouts which are closed at both ends thereof in the vicinities of the edges at opposite sides of the plate, and a second group of cutouts which are closed at one end thereof in a vicinity of an edge at one side of the plate from which they extend, an end opposite to the closed end of the cutout terminating in one of the edges of the plate which are perpendicular to the edges of the plate from whose vicinities the cutouts originate, thereby forming gaps in the perpendicular edges, and wherein the two plates of the plate pack are identical or differ with respect to at least one of thickness of the plate, number of the cutouts, width of the cutouts, distance between the cutouts, configuration of the cutouts, and inclination of the cutouts, and wherein one of the first and second plates is rotated from a parallel orientation by 180° around its central symmetry axis which is parallel to the edges of the sides of the plate in whose vicinity the cutouts originate, resulting in at least some of the cutouts of the first plate intersecting at least some of the cutouts of the second plate.
