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.
Claims19
A heat exchanger, particularly for motor vehicles, comprising:
- a collecting tank;
- and
- a single metallic tube plate which has a primary side, a secondary side, a wall thickness and collars having a wall thickness approximately equal the wall thickness of the metallic tube plate, the collars being formed continuously from the metallic tube plate, and in which tubes are to be held and sealed,
- wherein neighboring collars are alternately directed towards the primary side and towards the secondary side.
A heat exchanger, particularly for motor vehicles, comprising:
- 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 tubes are to be held and sealed,
- wherein neighboring collars are alternately directed towards the primary side and towards the secondary side;
- wherein the collars are disposed directly side by side, and
- wherein radii, at a transition from the collar to a plane of the plate, of two collars directed oppositely to one another merge directly into one another in an S-shape.
