Integrated, a header and an inner heat exchanger as well as the structural unit comprising a process for the preparation of the structural unit

摘要

The present invention relates to an integrated, a header (2) and an inner heat exchanger (3) comprising a structural unit (1) of a refrigerant circuit, in particular for a motor vehicle - air conditioning system, wherein the structural unit (1) a cylindrical housing jacket (5a) and the collector (2) a cylindrical, with the housing jacket (5a) an annular gap (6), which forms the outer wall of the container (2a), in which in the annular gap (6) a of the housing shell (5a) and of the container casing (2a) which is applied to the coiled tubing (4) is arranged.It is proposed that the coiled tubing (4) to the housing jacket (5a) and the container (2a) forms a non-positive lockup.
