Connecting device, and corresponding thermal exchanger, particularly for a motor vehicle

摘要

The invention relates to a connecting device having a female part (9) and a complementary male part (11), wherein the female part is realized as a sleeve (9) able to receive at least partially the associated male part (11) with a gap between the sleeve (9) and the male part (11) for receiving a brazing material (13). According to the invention, said sleeve (9) is designed at least partially with a conical shape comprising:
- a first substantially conical part (15) having a complementary shape to the male part (11), with a first inclination angle (± 1 ) with respect to a longitudinal axis (A) of the sleeve (9), and
- a second substantially conical part (17) with a second inclination angle (± 2 ) with respect to said axis (A), the second inclination angle (± 2 ) being larger than the first inclination angle (± 1 ). The invention also relates to a thermal exchanger comprising such a connecting device.
