Abstract (en)
[origin: WO2016012664A1] The invention relates to a heat exchanger with an outer tube carrying a low-pressure fluid and containing at least one pipe carrying a high-pressure fluid, such as an inner heat exchanger for a motor vehicle air-conditioning system, and such an air-conditioning system including said inner heat exchanger. Said heat exchanger (Ei1) comprises: an outer tube (10) having a longitudinal axis of symmetry (X), a length measured along said axis, and being suitable for carrying a low-pressure fluid (BP); and at least one pipe (20A) which is mounted radially inside the outer tube and which has a plurality of longitudinal channels suitable for carrying a high-pressure fluid (HP), the exchanger including soundproofing means capable of attenuating the noise transmitted by the low-pressure fluid. According to the invention, said means are at least partially formed by said at least one pipe twisted and/or wound around and along said axis over more than 50 % of said length.
