Abstract
The invention concerns a corrugated heat exchanger element () that can be produced from a metal strip and has a corrugation height (h) that lies between the crests () of the corrugations, in which the crests () form a first and second plane, consisting of several crests (), at least some of the crests () of each plane being connected to the heat exchanger walls (), and in which each crest () of the first plane is connected to the following crest () of the second plane by means of flanks (), and a flow channel () is formed between adjacent flanks (); structures (), whose direction of alignment () in one flank () intersects the direction of alignment () in the following flank (), are situated in the flanks (). In order to improve the efficiency of heat exchange, it is proposed in a first variant according to the invention that the elements of structures () be beads () or corrugations or the like that provide the flow channel with alternating constrictions () and widenings (), the adjacent flow channels () being essentially separated from each other in terms of flow. A second variant according to the invention proposes that the elements of the structures () be cuts () that connect the adjacent flow channels () together in terms of flow. A third variant prescribes that the elements of the structures be beads () or corrugations, in which cuts () lying in the direction of alignment () of the beads () or corrugations are arranged.
