Abstract:
A heat exchanger in the form of an evaporator comprising a bank of tubes (10) mounted between two fluid chamber covers (28, 46) by means of respective manifolds secure to the tubes (10) and suitable for being traversed by a fluid, wherein the tubes (10) each include at least two channels (12) separated by at least one longitudinal partition (68) and are arranged along a single row, parallel to two large faces (F1, F2) of the exchanger, wherein the circulation of the fluid takes place in at least two layers (SN1, SN2; SN3, SN4) parallel to the large faces of the exchanger and each formed by a part (G1; G2) of the channels (12) of the tubes, and wherein at least one of the fluid chamber covers (28, 46) comprises an internal longitudinal partition (48, 68) suitable for dividing a manifold chamber into at least two longitudinal compartments communicating respectively with the two layers, wherein said internal longitudinal partition is homogenously formed with said at least one of the fluid chamber covers,wherein each manifold (16) further comprises apertures (18) surrounded by collars (20) for the insertion of the extremities (14) of the tubes (10) of the bank, a manifold plate (22) is affixed by brazing to said manifold Eâ€”has been inserted and is equipped with a flat surface (22, 24) for brazing of at least one of said fluid chamber covers (28, 46) said manifold plate including apertures (26) aligned with the apertures (18) of the manifold.
