Abstract

A heat exchanger, particularly for motor vehicles, including a collecting tank and a metallic tube plate which has a primary side, a secondary side, and collars which are formed on it, and in which collars tubes are to be held and sealed. Neighboring collars (17, 19) are alternately directed towards the primary side (22) and towards the secondary side (23). In other words, collars disposed side by side are alternately formed in the direction of the air side and of the water side, whereby the distance between the collars can be reduced to a minimum.
