- This defines a heat exchanger comprising a plurality of tubes 10, possible spacers (not shown), two collectors 16 (of which only one is shown), two collector plates 22, as well as a box fluid 28 in the upper part and a fluid box 46 in lower part.
- the partition 68 of the fluid box 46 is provided for dividing each tube in such a way that compartment 70 communicates with G1 group channels and compartment 72 with the channels of group G2.
- Fluid circulation in the heat exchanger takes place in several passes as shown in Figure 5.
- the fluid enters compartment 58 through inlet manifold 54 and circulates in a first sub-layer SN1 formed by the channels of group G1 belonging to part of the tubes for gain compartment 70 by a vertical circulation of top to bottom.
- the fluid flows from bottom to top from the same compartment 70 to reach compartment 64, traffic taking place in a second SN2 sub-layer.
- the fluid circulates in the group G1 of the channels of the other tubes of the bundle.
- the fluid reaches compartment 72 by circulation vertical from top to bottom in a third SN3 sublayer, circulation taking place in the channels of the G2 group part of the tubes.

- the first two passes correspond SN1 and SN2 respectively.
- These two sub-layers belong to the same layer which extends to near the large face F1 of the heat exchanger.
- the circulation then takes place in two other passes which correspond to the SN3 and SN4 sub-layers.
- These two tablecloths are part of a second tablecloth which is connected in series at the first layer and which extends parallel to the large face F2 of the heat exchanger.
- the first layer is formed by the groups G1 of the channels (here three in number) and the second layer by the group G2 channels (here four in number).
- FIG. 6 shows a tube extruded 10 according to the invention which comprises a multiplicity of channels 12, in the example eleven in number.

- the two partitions 78 located in the central region have a thickness A and they are each followed by partitions having respective thicknesses B, C, D and E such that A> B> C> D> E.
- the thicknesses of the partitions thus decrease by the central region on the outskirts.
- the tube 10 is formed from a sheet 80 folded so as to include two opposite planar faces 82 joined by two end faces 84 of semi-circular profile.
- the sheet 80 has two longitudinal edges 86 assembled respectively against a intermediate part 88 of the stepped structure sheet forming a partition wall.
- the two edges 86 are assembled by longitudinal brazed joints 88 so to close the tube and define two channels 12.

- the plates 90 are mutually tightly soldered speakers respective edges so as to define two channels 12.
- the heat exchanger in Figure 9 is similar to that of Figure 4 but differs however in the structure of the fluid box 28 in the upper part and by the structure of the fluid box 46 in the lower part ( Figure 10).
- the fluid box 28 comprises, as in the case of the figure 4, an inlet manifold 54 and an outlet manifold 56 which communicate respectively with two compartments 58 and 60 separated by a longitudinal partition 48. But, the partition 48 continues beyond the transverse partition 52 for define two other compartments 98 and 100.
- the fluid box 46 has a longitudinal partition 68 which extends over part of its length and which joins a transverse partition 102. Another transverse partition 104 is provided at a distance from the partition 102. As a result, the fluid box 46 delimits two longitudinal compartments adjacent 70 and 72 on either side of the partition 68 and two transverse compartments 106 and 108 on both sides of the partition 104.
- the circulation of the fluid in the heat exchanger of Figures 9 and 10 are carried out in six passes divided in two plies.
- the fluid circulates successively in the first group of channels passing successively by compartments 54, 70, 98 and 106, 98 and 108.
- the fluid circulates successively in the second group of channels passing successively by compartments 108 and 100, 106 and 100, 72 and 56.
- the invention thus makes it possible to produce a heat exchanger obtained by brazing metal parts advantageously at aluminum base.
- the use of multi-channel tubes allows to define, in each tube, at least two groups of channels corresponding respectively to at least two layers of circulation. Because each collector offers a surface flat to bring back the collector plate, this allows to obtain a perfect seal between this flat surface and the fluid box and define compartments for the circulation of the fluid in several passes.
- the invention makes it possible to produce an exchanger heat with circulation in two layers, which leads to better temperature balancing of the exchanger. This is particularly interesting in the case where the heat exchanger is made in the form of a evaporator.
- each tablecloth at least two passes can be provided, usually two, three or four passes.
- the invention makes it possible to simplify the method of assembling the heat exchanger while providing a seal.
- the heat exchanger thus produced has a reinforced resistance to bursting and reduces pressure constraints on the fluid boxes and collectors, since each of the fluid boxes can have a lower height.
- the invention finds a particular application in the heating and / or air conditioning equipment for motor vehicles.
