Abstract (en)

[origin: WO2018065304A1] The invention relates to a matrix (30) for a heat exchanger between a first fluid and a second fluid, in particular for an air/oil application in a turbomachine. The matrix (30) comprises: a cross-passage in which the first fluid can flow; a grid with tubes (34) extending in the cross-passage and in which the second fluid circulates. The grid supports at least two fins (38; 40) that are in succession in the flow of the first fluid, in particular cooling fins. These successive fins (38; 40) extend in the first fluid along principal directions that are inclined with respect to one another.
