摘要:
The invention relates to a header (10) for a heat exchanger of a motor vehicle, designed to receive heat exchange tubes (12). The header comprises: a metal plate (18) through which the tubes (12) pass and which has two long edges (26) for the crimping of the header (10) to a header box (16); and a plate (22) comprising a polymer material, placed above the metal plate (18) and provided with openings (42) for receiving the tubes (12).
摘要:
The invention relates to a fin of a heat exchanger notably for a motor vehicle, comprising at least one orifice (22) of substantially longitudinal shape, intended to have passing through it a tube of the heat exchanger, said at least one orifice (22) being bordered by a flange (32) formed as an integral part of the fin. According to the invention, the flange (32) is made with a shape that is substantially curved with respect to the overall plane defined by the fin, so as to have a radius of curvature (RI, R2) between the overall plane defined by the fin (20) and the top of the flange (32) which top of the flange (32) projects with respect to the overall plane defined by the fin (20), the radius of curvature of the flange being at a minimum (R1) at the ends of the associated orifice (22) and at a maximum (R2) in a region that is substantially central along the longitudinal axis of the associated orifice (22).
摘要:
The invention relates to a heat exchanger comprising: at least one fin (4), - at least one row of tubes (2); the tubes being connected to the fin (4) by clamping the tubes (2) in a collar (6) arranged in the fin (4); and - at least one row (10) of louvres (12), arranged in the fin (4) and inserted between two tubes (2) of the row of tubes, each louvre (12) comprising a vane (14) having a free edge (16) and a connecting edge (18) connecting the louvre (12) to the fin (4). The connecting edge (18) of the vane (14) of at least the first louvre (12) of the row (10) forms the upstream edge with respect to the flow of air, the free edge (16) of the vane (14) forming the downstream edge.
