Heat exchanger assembly easier, and a heat transfer improved

摘要

Heat exchanger, for example for a motor-vehicle air-conditioning circuit (1) comprising a body in which are formed a series of first (18) fluid circulation channels and a series of second (20) fluid circulation channels. The body comprises a first element of the body (2) with a crenellated configuration comprising at least a first groove (14) and at least a first rib (6), each first rib (6) which contains at least one of the first fluid circulation channels (18), and a second body element (4) with a crenellated configuration comprising at least a second rib (8) and at least a second groove (16), each second rib (8) which contains at least one of the second fluid circulation channels (20), the first (2) and second elements of the body (4) being interleaved in such a way that each first rib (6) and each second rib (8) are respectively received in a second groove (16) and a first groove (14).
