Abstract:
The present invention relates to a heat exchange device (10) for a motor vehicle including a heat exchanger (12) with first and second collector plates (26; 28), first and second header boxes (30; 56) attached to the collector plates (26; 28) and a bundle (18; 20) of pipes (22) extending between the first and second collector plates (30; 56). Each of the collector plates (30; 56) forms a groove (54; 72) between the pipes (22) of the pipe bundle (18; 20) and a lateral end (50; 68) of the respective collector plate (30; 56). A perforated protective device (14) for the pipes (22) is attached to the heat exchanger (12) using attachment means (78, 80) bearing against the inside of the grooves (54, 72) in the first and second collector plates (26; 28).
