TUBE ENDPIECE FOR A HYDRAULIC CIRCUIT ELEMENT, PARTICULARLY FOR A HEAT EXCHANGER

摘要

The invention relates to a tube endpiece (60) configured in such a way that it can be fitted to one end of a fluid circulation tube (22) in order to form a hydraulic circuit. The endpiece comprises a sheet metal strip which is folded in order to form two branches (62) which can be applied against two opposite surfaces of the tube. One of the branches comprises at least one flared collar (66) with a turned-up annular edge (70) providing a junction area for an analogous endpiece. The thus stacked circuit elements are used to form heat exchangers, particularly in a motor vehicle.
