Abstract (en)

[origin: WO2021038152A1] The present invention relates to a heat exchanger comprising a bundle (3) for heat exchange between at least a first fluid (F1) and a second fluid (F2), the heat exchange bundle (3) being made up of at least two hollow elements (31) that are superposed and configured to respectively form a channel (35) inside of which the first fluid (F1) is intended to circulate, and to allow the circulation of the second fluid (F2) in a space (37) between the superposed hollow elements (31), at least one hollow element has a plurality of protuberances (5) extending within the space (37) for the circulation of the second fluid (F2), the protuberances (5) creating a link between two adjacent hollow elements (31), and at least a first hollow element (31a) and a second hollow element (31b) arranged facing one another are in fluid communication with one another via at least one hollow protuberance (5).
