The heat exchanger plate (10) comprises at least an opening (16) extending from a first face (12) to a second face (13) of the heat exchanger plate (10). The opening (16) is delimited by a collar (17) that is arranged around the opening (16). The heat exchanger plate (10) comprises at least a dimple (18) protruding above at least one of the faces (12, 13). Said dimple (18) comprises at least a flat area (19) and a slopped area (20), said slopped area (20) being interposed between the collar (17) and the flat area (19). ## Claims ### Claim 1 A heat exchanger plate of a heat exchanger, the heat exchanger plate comprising: two faces extending between two lateral edges and two longitudinal edges of said heat exchanger plate; at least an opening extending from a first face to a second face of the heat exchanger plate, the opening being delimited by a collar that is arranged around the opening; and at least a dimple protruding above at least one of the faces, wherein said dimple comprises at least a flat area and a slopped area, said slopped area being interposed between the collar and the flat area. ### Claim 2 (depends on 1) The heat exchanger plate according to claim 1, wherein the collar emerges over the first face of the heat exchanger plate and the dimple emerges over the second face of the heat exchanger plate. ### Claim 3 (depends on 1) The heat exchanger plate according to claim 1, wherein the slopped area being delimited by two opposite side lines, a first distance between both side lines is growing from the flat area of the dimple up to the collar. ### Claim 4 (depends on 1) The heat exchanger plate according to claim 1, wherein the slopped area is a curved area, the curvature center of the curved area is located at a second distance that is bigger than a depth of the dimple. ### Claim 5 (depends on 1) The heat exchanger plate according to claim 1, wherein the slopped area comprises a fringe that is tangent to the collar. ### Claim 6 (depends on 1) The heat exchanger plate according to claim 1, further comprising: a plurality of dimples that comprises at least a flat area and a slopped area, a third distance between an opening center of the opening and a limit between the slopped area and the flat area is constant from one dimple to another dimple. ### Claim 7 (depends on 1) The heat exchanger plate according to claim 1, wherein a thickness of the slopped area is at least constant from a limit between the slopped area and the flat area up to the collar. ### Claim 8 (depends on 1) The heat exchanger plate according to claim 1, further comprising at least a groove that is located in a core portion of the heat exchanger plate. ### Claim 9 (depends on 8) The heat exchanger plate according to claim 8, wherein a dimple comprising a summit, the summit of the dimple is located in a canal that is delimited by at least a groove. ### Claim 10 (depends on 8) The heat exchanger plate according to claim 8, wherein a dimple is a prolongation of a groove. ### Claim 11 (depends on 1) The heat exchanger plate according to claim 1, wherein the dimple comprises a chamfer, a width of the chamfer of the slopped area being bigger than a width of the chamfer of the flat area. ### Claim 12 A heat exchanger comprising: at least one heat exchanger plate comprising: two faces extending between two lateral edges and two longitudinal edges of said heat exchanger plate, at least an opening extending from a first face to a second face of the heat exchanger plate, the opening being delimited by a collar that is arranged around the opening, and at least a dimple protruding above at least one of the faces, wherein said dimple comprises at least a flat area and a slopped area, said slopped area being interposed between the collar and the flat area. ### Claim 13 (depends on 12) The heat exchanger according to claim 12, wherein the at least one heat exchanger plate comprises a first heat exchanger plate and a second heat exchanger plate, the flat area of both heat exchanger plates being in contact with each other.
