Abstract: The invention deals with a heat exchanger tube (1) for use in a heat exchanger tube (1) of a motor vehicle, the heat exchanger tube (1) comprising a pair (2) of plates (3) elongating along a longitudinal plan (A), the pair (2) of plates (3) comprising a first plate (3) and a second plate (4) joined to each other to form an inner area (5) dedicated to refrigerant fluid (RF) circulation and divided in at least six channels (6), at least one channel (6) is defined by a cross section area (S) that has a length (L), at least one of the plate is defined by a thickness (T) measured between an internal wall (7) of the plate and an external wall (8) of the plate opposed to the internal wall (7), wherein said thickness (T) is between 0.190 mm and 0.300 mm and said length (L) is between 2 mm and 5 mm.

Abstract: The invention relates to a heat exchanger plate (10) of a heat exchanger, the heat exchanger plate (10) comprising two faces (12, 13) extending between two lateral edges and two longitudinal edges (15) of said heat exchanger plate (10). 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).

Abstract: The invention relates to a tube (6) of a heat exchanger, the tube (6) extending mainly along a longitudinal direction and the tube (6) extending between two opposite lateral edges (21, 22) of the tube (6). The tube (6) comprises a plurality of canals (15a, 15b) that are parallel to the longitudinal direction. The tube (6) comprises a single first rank canal (15a) that is delimited by at least a first lateral edge (21) of the tube (6) and two first rank side walls (16a). The tube (6) comprises at least a second rank canal (15b) that is delimited by at least two second rank side walls (16b). A thickness (19) of both first rank side walls (16a) of the first rank canal (15a) is bigger than a thickness (19) of any second rank side wall (16b) of a second rank canal (15b) of the tube (6) and a thickness (19) of the first lateral edge (21) of the tube (6) is bigger than a thickness (19) of any second rank side wall (16b) of a second rank canal (15b). The tube (6) is obtained by folding a single sheet (23).
