Heat exchanger assembly of tubular elements nested, in particular for motor vehicle, 2004, and for its manufacture

摘要

The invention relates to a heat exchanger comprising a bundle of tubes which is obtained by assembly of tubular elements (1,4). br / the assembly is the result of the thermal contraction of the radial dimension of the outside of a male end (5) by a rise in temperature and then by thermal expansion and / or of the thermal expansion of the internal radial dimension of a female end (3) and of its thermal contraction. & br / application in particular to the evaporators or to a condenser forming part of the heating installations - air conditioning of motor vehicles.
