Abstract (en)
[origin: WO2021014091A1] The invention relates to a heat exchanger comprising a heat exchange bundle (3) transferring heat between a first fluid (F1) and a second fluid (F2), said heat exchange bundle (3) being composed of: at least two hollow elements (31) that are designed to form a channel inside which the first fluid (F1) is intended to flow and to allow the second fluid (F2) to flow in a space (37) between the stacked hollow elements (31), wherein at least one of the hollow elements (31) has a plurality of protrusions (5) that are located at least on one of the first (33a) and/or second (33b) faces of the hollow element (31), said protrusions (5) extending into the space (37) defined for the second fluid (F2) to flow in; and the heat exchange bundle (3) comprises at least one additional fin (6) in the space (37) defined between two adjacent hollow elements (31).
