Title: HEAT EXCHANGER, IN PARTICULAR FOR A MOTOR VEHICLE
Abstract:
The invention relates to a heat exchanger, comprising: - a heat exchange bundle comprising a plurality of tubes (11) the ends of which are substantially elongate in cross-section, - at least one header box comprising a header plate (21), the header plate (21) having a plurality of openings (211) respectively receiving one end of a tube (11), the openings (211) of the header plate (21) being substantially elongate in cross-section, and - at least one compressible seal (25) arranged around the ends of the tubes (11). According to the invention, - the tubes (11) are mechanically assembled to the header plate (21) by flaring the ends of the tubes (11), so as to at least partially increase the width of the ends of the tubes (11) in such a way as to compress the sealing means (25), and - the width (A) of each opening (211) of the header plate (21) is less than the width (li) of a tube end (11) before flaring.
