Abstract
A rib or fin for the joint ribbing of a plurality of heat exchanger tubes in a ribbed-tube heat exchanger for motor vehicles in which the ambient air flows as a first heat exchange fluid along the surface of the rib or fin and a second heat exchange fluid is conducted in the heat exchanger tubes. The rib is corrugated in the direction of flow of the first fluid. The rib is provided with shaped-on connecting sleeves which serve as a connection to the heat exchanger tubes. At least one wave crest of the corrugation extends between two connecting sleeves that are adjacent one another transversely to the flow direction of the first fluid, and local air guidance profiles are shaped in the corrugated surface of the rib in the spaces between the connecting sleeves. The air guidance profiles are constituted by at least predominantly closed bulges which have a lower height than the distance between the ribs when assembled in the heat exchanger and the bulges are each disposed on a slope of the corrugation.
