Heat exchanger for heating/conditioning system for car has slots defined by flanges allowing setting of flat pipes and bell-shaped four-sided cap with rims attached to edges of collecting plate

摘要

Slots (24) are defined by flanges (26) spreading inwards of collecting case to allow setting by brazing of flat pipes (21)' tips (23). Longitudinal sides (31, 32) of collecting plate (25) spread from end sides (29, 30) of flange slightly towards direction of pipes. Transversal sides (34, 35) of plate spread from outer transversal sides (27a, 27b) of flanges. Transversal sides form, with longitudinal sides, four-angled open skirt. Bell-shaped four-cornered cap (40) has rims (41, 42, 43, 44) attached by brazing to edges (31, 32, 34, 35) of collecting plate.
