A counter-current heat exchanger for a turbomachine comprising a first and a second circuit, the first and the second circuit being respectively configured to receive a first gas flow and a second gas flow, each circuit including a secondary inlet manifold, an exchanging part and a secondary outlet manifold; the exchanging parts of the first circuit and of the second circuit being delimited by exchange walls configured to direct the first and the second gas flow along a first direction; and wherein the secondary inlet manifold and the secondary outlet manifold of the first circuit extend along a second direction substantially perpendicular to the first direction, and open onto a same face of the exchanger.
The heat exchanger as claimed in claim 2,
The heat exchanger as claimed in claim 1, wherein the first circuit comprises a plurality of secondary inlet manifolds and a plurality of secondary outlet manifolds configured such that at least one secondary inlet manifold communicates with at least two secondary outlet manifolds.
The heat exchanger as claimed in claim 1, wherein the secondary inlet manifold and the secondary outlet manifold of the second circuit are respectively configured so that the directions of flow of the second gas flow at the inlet and the outlet of the second circuit are substantially along the first direction.
A turbomachine comprising a heat exchanger as claimed in claim 1.
A method for manufacturing a heat exchanger as claimed in claim 1, comprising at least one powder bed additive manufacturing step.
