Abstract
The invention relates to a heat exchanger, especially for motor vehicles, comprising a soldered heat exchanger network made of flat pipes (2,3) and corrugated ribs (1). A liquid and/or vaporous-type medium can flow through the flat tubes (2, 3) and air can circulate around the corrugated ribs. One corrugated rib respectively comprises two surfaces (4,5) which are arranged in an essentially parallel manner in relation to each other and which are connected respectively by an arch-shaped piece (6) which is soldered to a flat pipe, said arch-shaped piece comprising three sections (6a,6b,6c) which have different curvatures.
Claims15
A heat exchanger, comprising:
- a soldered heat exchanger network comprising flat tubes and corrugated ribs configured so that a liquid and/or gaseous medium can flow through the flat tubes and air can flow around the corrugated ribs, and
- a corrugated rib having at least two rib surfaces which are arranged essentially parallel to one another and are connected by an arcuate piece joined to a flat tube,
- wherein the arcuate piece has a lower curvature in a middle portion than in a first outer portion and in a second outer portion,
- wherein the arcuate piece has in the middle portion a radius of curvature R1 which is greater than a rib height RH of the corrugated rib,
- wherein the arcuate piece has in the first outer portion a radius of curvature R2 which is lower than half a rib height RH of the corrugated rib.
