Abstract (en)
[origin: WO8905432A1] In a countercurrent heat-exchanger (12), the passages through which the media (2, 3) flow have an extension perpendicular to the exchange surfaces, through which most of the heat exchange occurs, not greater than approximately twice the thickness (S) of the boundary layer of the flowing media (2, 3), and the passages are delimited by their sheet metal elements (1) (Fig. 5).
