The heat exchanger is constituted by a core (1) to which are fixed inlet and outlet air scoops. On one face of the core the air penetrates through regularly spaced angular sectors (5) and gas leaves through alternate angular sectors (6). On the core opposite face the air leaves through angularly spaced angular sectors (3) alternating with gas inlet angular sectors (4). The core is formed by winding a pair of sheets around an axis (z). One sheet is longitudinally rippled whilst the other sheet is transversely rippled. The first sheet has three axial ripple zones near the edges and a central zone. The other sheet is also rippled on these same three zones and also has inlet-outlet zones, with its edges alternately curved to form fluid inlet-outlet scoops. |
