Abstract (en)

[origin: WO03098142A1] The invention relates to a heat carrier comprising at least one collector pipe (1) for receiving the ends of flat pipes (10a), especially for a CO<2> air conditioning unit for motor vehicles. The collector pipe (1) is formed by an open hollow profiled section (7) with edges (8, 9) forming a continuous longitudinal slit extending in a longitudinal direction and the ends of the flat pipes (10a), which are twisted at an angle of 90 DEG , are received in a fluidically tight manner in the longitudinal slot. According to the invention, the edges (8,9) partially abut, forming a separating joint (4) and are partially rolled back, forming receiving openings for the ends of the flat pipes (10a). The receiving openings are produced by plastic deformation.
