Abstract

A heat exchanger (10) for a transmission unit of an aircraft (1) is described that comprises: a first module (23) defining a first feed path (P) for a first fluid to be cooled; a second module (33) defining a second feed path (T) for a second cooling fluid; the first and second feed paths being thermally coupled to each other; each second module (33) comprising: at least one cell (45) formed by an inlet (39) for a second cooling fluid; an outlet (40) for the second cooling fluid, which is arrange on the opposite side to the inlet (39) along a first direction (X); a first wall (35) thermally coupled to the first path (P); a pair of second walls (36a, 36b); and a plurality of fins (55) projecting in a cantilever fashion from the first wall (35). The heat exchanger (10) further comprises at least a first row (61) of fins (55), which lie on a plane orthogonal to the first direction (X), the fins (55) of the first row (62) extending at progressively increasing distances from one (36a) of the second walls (36a, 36b) along a second direction (Y) orthogonal to the first direction (X).
