Abstract: The object of the invention is, among others, a tube for a heat exchanger, including: a first tubular element and at least one second tubular element each tubular element including two juxtaposed longer walls having essentially flat surface connected by a pair of shorter walls to form a closed profile of each tubular element. The tube further includes at least one reversal element configured to fluidly connect the first tubular element and the second tubular element. The tubular elements are arranged next to each other, so that the respective longer walls are coplanar with respect to each-other. The reversal element is made integral with the tubular elements.

Abstract: A header-tank assembly for a fluid, including: a header, a cover, a first baffle forming an end wall for a fluid channel at an end of the header, a second baffle including a first opening configured to provide a fluidal communication between the header-tank assembly and a fluid loop, a distribution device located between the first baffle and the second baffle, the distribution device including a first open end and a second open end. The first open end of the distribution device is in a contact with the first baffle and the second open end is fluidly connected with the first opening of the second baffle. The first baffle includes a sealing portion configured to be fixed to the first open end of the distribution device to form a fluid-tight connection blocking the exit of the fluid from the first open end of the distribution device.

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 sloped area (20), said sloped 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).

Abstract: The invention relates to a connecting device having a female part and a complementary male part, wherein the female part is a sleeve able to receive at least partially the associated male part with a gap between the sleeve and the male part for receiving a brazing material. The sleeve at least partially has a conical shape. The conical shape has a first substantially conical part having a complementary shape to the male part, with a first inclination angle with respect to a longitudinal axis of the sleeve. The conical shape also has a second substantially conical part with a second inclination angle with respect to the axis, with the second inclination angle being larger than the first inclination angle.
