Abstract:
1. A heat exchanger plate formed from a quadrilateral plate having a pair of opposing first plate edges and a pair of opposing second plate edges, the heat exchanger plate comprising: first surface portions each along a first middle edge portion of a first plate edge, each first surface portion including a first contacting region; second surface portions each along a second middle edge portion of a second plate edge, each second surface portion including a second contacting region; at least two corner surface portions including a first corner edge portion and a second corner edge portion, which form continuations of the corresponding first middle edge portion and the second middle edge portions respectively; wherein the first surface portions are bent to a first side of the quadrilateral plate resulting in a first partial fluid channel, and the second surface portions are bent to a second side of the quadrilateral plate resulting in a second partial fluid channel; wherein the first contacting regions extend along coplanar edge lines defining a plane; and wherein the at least two corner surface portions are bent inward towards the first partial fluid channel and away from the first surface portion such that the first corner edge portions are in the plane and tilted at a non-zero angle α in the range 0°<α<90° with respect to the corresponding edge line, while the respective second corner edge portions are substantially perpendicular to the plane.
