Coaxial heat exchanger, in particular, for a vehicle heating/ventilating and/or air-conditioning plant comprises at least one structure whose wall thickness with respect to at least one of its other structures is reduced

摘要

The coaxial heat exchanger (1) with outer, inner and intermediate structures (6, 7, 12), in particular, for a vehicle high-pressure heating, ventilating and/or air-conditioning plant comprises at least one structure whose wall thickness with respect to at least one of its other structures is reduced. Independent claims are also included for: (A) a method for producing the proposed coaxial heat exchanger; (B) a ring-shaped plastic sealing element for the proposed heat exchanger.
