- the turbojet engine 2 comprises a first compression level, called a low-pressure compressor 5, a second compression level, called a high-pressure compressor 6, a combustion chamber 8 and one or more levels of turbines 10.
- the mechanical power the turbine 10 transmitted via the central shaft to the rotor 12 sets in motion the two compressors 5 and 6.
- the latter comprise several rows of rotor blades associated with rows of stator vanes.
- the rotation of the rotor 12 about its axis of rotation 14 thus makes it possible to generate an air flow and to compress it progressively to the inlet of the combustion chamber 8.
- a commonly designated fan or fan inlet fan 16 is coupled to the rotor 12 via a transmission 17. It generates a flow of air which is divided into a primary flow 18 passing through the various levels of the turbomachine mentioned above, and a secondary flow 20.
- the secondary flow can be accelerated so as to generate a push reaction.
- the transmission 17 and the bearings 22 of the rotor 12 are lubricated and cooled by an oil circuit. Its oil passes through a heat exchanger 24 placed in a sleeve 26 taking part of the secondary flow 20 used as a cold source.
- FIG. 2 shows a plan view of a heat exchanger 24 such as that shown in Figure 1.
- the heat exchanger 24 has a generally arcuate shape. It matches an annular housing 28 of the turbomachine. It is crossed by the air of the secondary flow which forms a first fluid, and receives oil forming a second fluid. It comprises a matrix 30 disposed between two collectors 32 closing its ends and collecting the second fluid; for example the oil during its cooling.
- the exchanger may be mixed and comprise both types of matrices described below.

- the crossing can usually form a corridor; possibly of variable external contour.
- a network receiving the second fluid is disposed in the bushing.
- the network may comprise a series of tubes 34.
- the various tubes 34 may provide passages 36 between them.
- the tubes 34 support fins (38; 40). These fins (38; 40) can be placed one after the other according to the flow of the first fluid, so that they form successive fins according to this flow.
- the concentration of fins in the matrix 30 can vary.

- the front fins 38 are placed in a front plane, and the rear wings 40 are placed in the background.

- two successive fins (38; 40) may each extend into the first fluid in a proper main direction. These main directions can be inclined relative to each other, in particular inclined by 90 °. From the front, the successive fins (38; 40) draw crosses, for example series of crosses connecting the tubes 34. Since the fins (38; 40) are inclined relative to the tubes 34, they form triangulations, or legs by force.
- intersections 42 in the space of the successive fins (38; 40) is at a distance from the tubes 34, possibly halfway between two successive tubes 34. This central position of the intersections 42 avoids amplifying the losses in the boundary layers.

- the matrix 30 has an inlet 41 and an outlet 43.
- the primary flow 20 takes the matrix 30 from the inlet to the outlet, thus defining the direction of flow of the first fluid, possibly its main direction of flow.
- the matrix 30 may comprise an outer envelope 45.
- the outer envelope may form an outer skin of the matrix 30.
- the outer envelope 45 may delimit, in particular surround the crossing and / or the network.
- the input 41 and the output 43 can be made in the outer envelope 45.
- the latter can form a support for the entities inside.
- the partitions 48 of the tubes 34 form the structure of the matrix 30, the heat exchange taking place at the cross-section of their thicknesses.
- the tubes 34 can be partitioned by an inner wall 35, which increases the rigidity of these tubes 34.
- the interior of the tubes is embellished with obstacles (not shown) to generate turbulence in the second fluid in order to increase the heat exchange.
- the fins (38; 40) of the different fin planes can be spaced from the other fins, which reduces the mass and the occupation of the bushing.
- the front fins 38 can join the upstream tubes, and the rear fins 40 join the tubes arranged downstream.
- This configuration makes it possible to connect the tubes 34 to each other despite the presence of the passages 36 separating them.
- the tubes 34 may have rounded profiles, for example in ellipses. They are thinned transversely to the flow of the first fluid to reduce the pressure losses, and thus increase the possible flow.
- the tubes 34 placed in the extension of each other according to the flow of the first fluid are separated by the passages 36.
- other passages 36 separate the superimposed tubes. Since these passages 36 communicate with each other, the matrix becomes through and the flow of the first fluid can circulate in a straight line as diagonally with respect to the secondary flow 20.

- the set of fins (138; 140) can form a succession of successive crosses.
- the different crosses are rotated relative to each other in order to optimize the heat exchange while limiting the losses of loads. For example, each cross is rotated 22.5 degrees from its upstream cross. A pattern with four crosses rotated regularly can be repeated.
- the crosses form helical passages 136 within the channels 146, for example four helical passages 136 wound around each other.
- the channels 146 may be straight or twisted.
- FIG. 7 is a partial section along the axis 7-7 drawn in FIG. 5.
- Three channels 146 are represented, as are four portions of mesh 144 in FIG. which circulates the second fluid; for example oil.
- the fins (138; 140) and thus the crosses they form appear in section.
- the front wings 138 are visible in all their lengths while the rear wings 140 are only partially visible since they remain in section.
- the following crosses are also partially represented via their hubs 150 of crossing their fins.

- the angle of inclination ⁇ the fins planes 152 and the general flow of the first fluid can be between 30 ° and 60 °.
- the angle of inclination ⁇ may be equal to 45 °. From this it follows that the passages 146 comprise sections inclined with respect to the general direction of the flow of the first fluid through the matrix 130. This arrangement causes the first fluid to change section as it circulates, and to better cool the offset fins.
