Corrugated heat exchange element

Abstract

Abstract The invention concerns a corrugated heat exchanger element ( 1 ) that can be produced from a metal strip and has a corrugation height (h) that lies between the crests ( 2 ) of the corrugations, in which the crests ( 2 ) form a first and second plane, consisting of several crests ( 2 ), at least some of the crests ( 2 ) of each plane being connected to the heat exchanger walls ( 3 ), and in which each crest ( 2 ) of the first plane is connected to the following crest ( 2 ) of the second plane by means of flanks ( 4 ), and a flow channel ( 20 ) is formed between adjacent flanks ( 4 ); structures ( 5 ), whose direction of alignment ( 15 ) in one flank ( 4 ) intersects the direction of alignment ( 15 ) in the following flank ( 4 ), are situated in the flanks ( 4 ). 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 ( 5 ) be beads ( 6 ) or corrugations or the like that provide the flow channel with alternating constrictions ( 11 ) and widenings ( 10 ), the adjacent flow channels ( 20 ) being essentially separated from each other in terms of flow. A second variant according to the invention proposes that the elements of the structures ( 5 ) be cuts ( 7 ) that connect the adjacent flow channels ( 20 ) together in terms of flow. A third variant prescribes that the elements of the structures be beads ( 6 ) or corrugations, in which cuts ( 7 ) lying in the direction of alignment ( 15 ) of the beads ( 6 ) or corrugations are arranged.
