- Such an armature 16 consists of two similar plates 20 (hereinafter wing plates) nested one inside the other. To understand the structure of the armature 16, it is therefore necessary to first describe one of these fin plates 20. This is what will be done in the following with reference to Figures 4 and 5.

- the lateral direction X of the finned plate 20 is defined for the following, in which extend its short sides 24a, 24b, its longitudinal direction Y, in which extend its long sides 26a, 26b, and finally its transverse direction. Z, normal to the basic plane PB. To simplify the representation, only a portion of the plate 20 is shown in Figures 4 and 5. As indicated by the dashed lines, the plate continues identically in the longitudinal direction Y.
- the longitudinal direction Y of a finned plate 20 included in this exchanger is parallel to the longitudinal direction Y1 of the exchanger 80.

- This offset, in the lateral direction X, between the rank 2N and rank 2N + 1 bands, is here equal to a quarter of the length L of a fin, measured in the same lateral direction X. It is observed, again by observing FIG. 6, that all the bands of rank 2N have the same length, greater than that of the bands of rank 2N + 1.
- the rank 2N strips comprise, in fact, a fin portion 50 in addition, at one of their ends. Each of these fin parts is folded towards the base plane according to a triangular profile 50, as illustrated in FIG. 4. From FIG. 6, it is further apparent from said fin portion has a length equal to L / 2. in other words half the length of a fin.
- two immediately adjacent wings of rank 2N and 2N + 1 are spaced, in the longitudinal direction Y, by a distance at least equal to the width of a strip of fins in this direction Y.

- the distance separating two successive wing branches of the same orientation, in the longitudinal direction Y, is denoted by D, and D is here equal to 3 times the width of a strip of fins.
- a fluid F passing through the armature 16, in the longitudinal direction Y successively encounters (if we consider portions of the width of a band of fins) a fin, then nothing, nothing, nothing, a fin, nothing, nothing, nothing, a fin, etc.
- a sheet of fluid of the same cross section as a fin and flowing along F passes closer to the fins of rank 4N in this longitudinal direction Y.
- the periodicity of the fins inside the armature 16 may be different from 4, and in particular greater than 4.

- each fin plate 20 has, at each of its lateral ends 126a, 126b, 226a, 226b an edge respectively 125a, 125b, 225a, 225b folded perpendicularly to the base 22 and of constant height over the entire width of the finned plate 20.
- each folded edge 125a, 125b, 225a, 225b is pressed against the side 65 of a spacer 60a, 60b.
- the height of the folded edges of each finned plate is chosen to be less than at least half the thickness d3 of the spacer, so that the respective edges of the two finned plates 120, 220 opposite do not overlap.
- the shape of the fins and in particular their oblique walls 42, 44 give them a relative elasticity, which makes it possible to reduce the dimensional constraints during assembly between the separating plates 70, 72.
- the oblique parts of the fins flex when the plates 70, 72 are brought closer to each other until they come into contact with the bearing faces of the struts.
