Improved collector case for heat exchanger and corresponding heat exchanger

摘要

The box e.g. lower collector box (14), has a cover (45) including an intermediate plate (43) comprising end faces that are pierced with openings along a longitudinal direction. The cover has a stamped plate (44) provided with an inner face. The plates are connected at a level of the faces adapted to be soldered with each other and with the openings. Humps of the plate (44) and the openings of the plate (43) define a collector volume to connect reception openings (28) of a collector plate (26) along the longitudinal direction.
