Heat exchanger has a tubular elements nested, in particular for motor vehicle, 2004, and method of manufacturing

摘要

The invention relates to a heat exchanger of the type comprising a beam with a tubular elements fitted. & br / a male end (2) of a first tubular element (1) is fitted into a female end (4) of a second tubular element (3), and a clamping ring (5) which has previously been expanded by an increase in temperature is acquired by a return to ambient temperature, which makes it possible to ensure a sealed assembly. & br / application in particular to the evaporators and a condenser forming part of the heating and air-conditioning installations for motor vehicles.
