Abstract
In a matrix for a heat exchanger to exchange heat between a first fluid and a second fluid, the first fluid being for instance air and the second fluid being for instance oil, the matrix includes a channel for the first fluid, an array of passages for the second fluid, the passages extending in the channel. The array supports at least two cooling fins. The matrix is made by a process of additive manufacturing. The fins are inclined with respect to each other along the direction of the flow of the first fluid. The array defines rectangular corridors for the first fluid.

Matrix for a heat exchanger, the matrix comprising:
- an array of walls defining a plurality of corridors for a first fluid, each of the corridors having a quadrangular cross-section, each of the corridors having a central axis;
- the array of walls defining passages for a second fluid;
- wherein the array of walls supports at least two fins arranged one behind the other along the central axis of one corridor of the plurality of corridors;
- wherein the at least two fins are planar, extend in parallel with the central axis and are inclined relative to one another around the central axis;
- and
- wherein each of the at least two fins has two ends, both ends of each of the at least two fins being connected to the array of walls.
Matrix for a heat exchanger, the matrix comprising:
- an array of walls defining square corridors for a first fluid and rectangular passages for a second fluid.
