Abstract: A diagonal gasket support (22) in a heat exchanger cassette adapted for a heat exchanger having a contact-free flow channel (28), where the cassette (11, 29) comprises two plates (12) of the same type, where each plate is provided with a corrugated pattern having a plurality of ridges (19) and valleys (20), characterized in that the diagonal gasket support (22) comprises a plurality of indentations (23) and protrusions (24) positioned adjacent each other along a diagonal gasket groove (21). The advantage of such a diagonal gasket support is that a contact-free support at the diagonal gasket is obtained.

Abstract: The invention relates to a heat exchanger plate for a plate heat exchanger, whereby the heat exchanger plate has a number of ports, distribution regions, adiabatic regions, a heat transfer region, and an edge region which extends outside the ports and the regions, whereby the heat exchanger plate includes a gasket groove extending in the edge region outside the regions and round the ports, whereby the gasket groove accommodates a gasket for sealing abutment against an adjacent heat exchanger plate in the plate heat exchanger where the gasket groove creates at least a recess of the heat transfer region along each side of the heat transfer region and that the recess enables a clip-on tab to be securely fastened to an edge region of the heat exchanger plate at the recess.

Abstract: A plate for the use in a heat exchanger cassette, where the plate comprises a corrugated pattern having a plurality of ridges (9) and valleys (10), and where the plate comprises a sealing gasket groove (3) encircling a heat transfer surface (8) that will be part of a contact-free fluid channel when two cassettes comprising at least one plate each are positioned adjacent each other, wherein the sealing gasket groove (3) comprises a base surface with a first, flat section (12) and a second, bent section (13), and where the bent section is angled with the angle ?. The advantage of the inventive plate is that an airtight heat exchanger cassette can be obtained in an easy and cost-effective way.

Abstract: The invention refers to a heat exchanger plate (11), a pair of heat exchanger plates, and a plate package for a plate heat exchanger. Each heat exchanger plate includes a heat transfer area (33) and a distribution area (34) which adjoins the heat transfer area along a borderline (35). The distribution area has projections and depressions abutting depressions and projections, respectively, on a distribution area of adjacent heat exchanger plates. The heat transfer area has projections (51) and depressions (52) abutting depressions and projections, respectively on a heat transfer area of adjacent heat exchanger plates for forming first contact surfaces positioned at a first distance from each other along a direction substantially parallel with the borderline.

Abstract: Heat exchanger device, comprising a plurality of cassettes, where a first cassette comprises two plates of a first type and a second cassette comprises two plates of a second type, where each plate is provided with a corrugated pattern having a plurality of ridges and valleys with side walls there between, where the corrugated pattern comprises undulations parallel to the direction of the corrugated pattern, where the cassettes are mounted adjacent each other at a predefined distance, and where the perpendicular distance between the side walls of two adjacent cassettes is substantially constant over the width of the heat exchanger device. The advantage of this device is that the difference in flow restriction in the heat exchanger is minimised.
