Abstract: The invention relates to an aircraft pylon comprising a cooling exchanger (10) with counterflow of a flow of hot primary air (22) by a flow of cold secondary air (24) flowing oppositely to each other in a longitudinal direction (L), characterized in that it comprises two bundles (10a, 10b) juxtaposed on both sides of a central axis (12) and each comprising a plurality of parallel longitudinal plates (15) forming a hot pass and a cold pass of the bundle, and in that one of the hot or cold passes of each bundle is supplied by a central inlet (14a) common to the two bundles (10a, 10b) and one of the hot or cold passes of each bundle opens into a central outlet (16) common to the two bundles, said inlets (14b, 14c) and outlets (16b, 16c) of the conjugate passes, referred to as side inlets and outlets, being separate and diverging laterally from said central axis (12).

Abstract: A tubular heat exchanger (10) comprising: a fluid circulation chamber (20) intended to be supplied with a first fluid, referred to as outer fluid, brought to a first temperature, a heat exchange matrix (30) housed in said circulation chamber and formed by a plurality of heat exchange tubes (31) each comprising at least one pair of ducts (32; 33) nested one inside the other, extending along a direction, referred to as longitudinal direction, and defining: a channel for circulating a fluid, referred to as inner channel (32c; 33c), suitable for being able to be supplied with a second fluid, referred to as inner fluid, brought to a second temperature, and a channel for the circulation of a fluid, referred to as intermediate channel (32d; 33d), and suitable for being able to be supplied with a third fluid, referred to as intermediate fluid, brought to a third temperature, different from said first temperature.

Abstract: The invention relates to a heat exchanger that is configured to permit an exchange of heat between a first fluid and a second fluid that circulate in passage paths formed by plates (14a, 14b) and fins (16a, 16b) of the heat exchanger, the fluids flowing in a multitude of passage channels (10) each consisting of a closed space (12) delimited by two adjacent plates and two adjacent fins, characterized in that each plate extends along a non-planar surface following at least a first oscillating curve, and each fin further following at least one second oscillating curve along at least one second main direction, in such a way that each passage path allows the fluid to flow in the closed space along a fluid direction defined by a generatrix that is a combination at least of the first oscillating curve and the second oscillating curve.
