- Each ventilation tube 8 opens into a separate orifice of each manifold 12.
- each air manifold 12 has as many orifices as it receives ventilation tubes 8, a ventilation tube 8 being received in each of the orifices of the air collector 12.

It is thus possible to adapt the flow of air ejected by the ventilation device 2 and, by the same, the flow of air Fl passing through the heat exchanger. For example, again, it is possible to produce an air flow Fl only with regard to certain elements to be cooled. This may be more particularly advantageous when the ventilation device 2 is associated with different heat exchangers and / or different elements to be cooled, arranged in defined zones facing the ventilation device 2. By “defined zones”, it is understood here that areas that can advantageously be distinct, without overlap.

- the flow of air ejected through the openings 40 runs along at least part of the first profile 42 of the aerodynamic tube 8, for example by Coanda effect. Taking advantage of this phenomenon, it is possible, thanks to the entrainment of the ambient air in the created air passage, to obtain a flow of air sent to the heat pipes identical to that generated by a propeller fan. while consuming less energy.
- the air flow sent to the row of heat transfer tubes 4 is the sum of the air flow ejected by the slots and induced air.
- a turbomachine of reduced power compared to a conventional propeller fan generally implemented in the context of such a heat exchange module.
- a first profile 42 having a Coanda surface also makes it possible not to to have to direct the openings 40 directly towards the heat-transfer tubes 4, and thus to limit the size of the aerodynamic tubes 8. It is thus possible to maintain a larger passage section between the aerodynamic tubes 8, which promotes the formation of a greater induced air flow.
- the opening 40 is, in Figure 5, delimited by lips 40a, 40b.
- the spacing e between the lips 40a, 40b, which defines the height of the opening 40 may be greater than or equal to 0.3 mm, preferably greater than or equal to 0.5 mm, more preferably greater than or equal to 0.7 mm and / or less than 2 mm, preferably less than or equal to 1.5 mm, more preferably less than 0.9 mm, more preferably less than or equal to 0.7 mm.
- the height of the slot is the size of this slot in the direction perpendicular to its length. The lower the height of the slot 40, the greater the speed of the air flow ejected by this slot. A high speed of ejected airflow results in a high dynamic pressure.
- This dynamic pressure is then converted into static pressure in the mixing zone of the air flow ejected by the slot 40 and the induced air flow.
- This static pressure makes it possible to overcome the pressure losses due to the presence of the heat exchanger downstream of the ventilation device, in order to ensure a suitable flow of air through the heat exchanger.
- These pressure losses due to the heat exchanger vary in particular as a function of the heat pipe pitch and the pitch of the fins of the heat exchanger, as well as the number of heat exchange modules that can be superimposed. in the heat exchanger.
- a slot height too low induces high pressure losses in the ventilation device, which involves using an air propulsion device or several oversized (s). This can lead to additional cost and / or create a space incompatible with the space available in the vicinity of the heat exchange module in the motor vehicle.
- the outer lip 40a here consists of the extension of the wall of the aerodynamic tube 8 defining the leading edge 37.
- the inner lip 40b is constituted by a curved portion 50 of the first profile 42.
- An end 51 of the inner lip 40b can extend, as shown in Figure 5, in the direction of the second profile 44, beyond a plane L normal to the free end of the outer lip 40a.
- the end 51 of the inner lip 40b can extend, towards the leading edge 37, beyond the normal plane L at the free end of the outer lip 40a.
- the end 51 can then contribute to directing the flow of air flowing in the aerodynamic tube 8 towards the opening 40.
- the opening 40 of the aerodynamic tube 8 can be configured so that a flow of air flowing in this aerodynamic tube 8 is ejected through this opening 40, flowing along the first profile 42 substantially to the trailing edge 38 of the aerodynamic tube 8.
- the flow of airflow along the first profile 42 may result from the Coanda effect. It is recalled that the Coanda effect is an aerodynamic phenomenon that results in the fact that a fluid flowing along a surface at a short distance from it tends to outcrop or even hang on it.
- the maximum distance h between the first 42 and the second 44 profiles, measured according to an alignment direction of the aerodynamic tubes 8, is downstream of the opening 40.
- the maximum distance h may be greater than 10 mm, preferably greater than 11 mm and / or less than 20 mm, preferably less than 15 mm.
- the maximum distance h is substantially equal to 11.5 mm.
- a height h too low can cause significant pressure losses in the aerodynamic tube 8 which could require to implement a turbomachine more powerful and therefore more voluminous.
- a height h too large limits the passage section between the aerodynamic tubes for the induced air flow. The total air flow directed to the heat exchanger is then also reduced.
- the first profile 42 here comprises a curved portion 50 whose apex defines the point of the first profile 42 corresponding to the maximum distance h.
- the curved portion 50 may be disposed downstream of the opening 40 in the direction of ejection of the air flow.
- the convex portion 50 may be contiguous with the inner lip 40b delimiting the opening 40.
- the first profile 42 of the aerodynamic tube 8 of the example of Figure 5 comprises a first portion 52 substantially straight.
- the second profile 44 comprises, in the example illustrated in FIG. 5, a substantially rectilinear portion 48, extending preferably over a majority of the length of the second profile 44.
- the length 1 of the first rectilinear part 52 measured in a direction perpendicular to the longitudinal direction of the aerodynamic tube 8 and the alignment direction of the row of aerodynamic tubes, may be greater than or equal to 30 mm, preferably greater than or equal to 40 mm, and / or less than or equal to 50 mm.
- this first rectilinear part is particularly desired for guiding the air flow ejected from the opening 40, which ensures a greater suction of air.
- the length of this first rectilinear part is however limited because of the corresponding size of the ventilation device and its consequences on the packaging of the ventilation device or the heat exchange module.
- the first rectilinear portion 52 of the first profile 42 and the straight portion 48 of the second profile 44 may form a non-flat angle Q.
- the angle Q thus formed may in particular be greater than or equal to 5 °, and / or less than or equal to 20 °, more preferably substantially equal to 10 °.
- This angle of the first rectilinear portion 52 with respect to the rectilinear portion 48 of the second profile 44 makes it possible to accentuate the expansion of the flow of air ejected by the opening 40 and undergoing the Coanda effect forcing it to follow the first profile 42 , this accentuated relaxation to increase the induced air flow.
- An angle Q too great, however, may prevent the realization of the Coanda effect, so that the flow of air ejected through the opening 40 may not follow the first profile 42 and, therefore, not to be oriented correctly towards the heat exchanger 2.
- the first profile 42 may comprise, as illustrated in FIG. 5, a second rectilinear portion 38a, downstream of the first straight portion 52, in the direction of ejection of the air flow, the second straight portion 38a extending substantially parallel to the rectilinear portion 48 of the second profile 44.
- the first profile 42 may also include a third straight portion 54, downstream of the second straight portion 38a of the first profile 42.
- the third straight portion 54 may form a non-flat angle with the rectilinear portion 48 of the second profile 44.
- the third rectilinear portion 54 may extend, as illustrated, substantially to a rounded edge connecting the third rectilinear portion 54 of the first profile 42 and the straight portion 48 of the second profile 44.
- the edge rounded can define the trailing edge 38 of the cross section of the aerodynamic tube 8.
- the rectilinear portion 48 of the second profile 44 extends in the example of Figure 5 over the majority of the length c of the cross section.
- This length c is measured in a direction perpendicular to the longitudinal direction of the aerodynamic tubes 8 and the alignment direction of the row of the aerodynamic tubes 8.
- This direction corresponds, in the example of Figure 4, substantially to the direction of the flow of the induced air flow.
- the length c of the cross section (or width of the aerodynamic tube 8) may be greater than or equal to 50 mm and / or less than or equal to 70 mm, preferably substantially equal to 60 mm.
- the inventors have found that a relatively large length of the cross section of the aerodynamic tube makes it possible to more effectively guide the flow of air ejected through the opening 40 and the induced air flow, which mixes with this flow of air ejected.
- too great a length of the cross section of the aerodynamic tube 8 poses a problem of packaging of the ventilation device 2.
- the size of the heat exchange module can then be too large compared to the place that is available in the motor vehicle in which it is intended to be mounted.
- the packaging of the heat exchange module or the ventilation device can also be problematic in this case.
- the second straight portion 38a of the first profile 42 and the portion 38b of the straight portion 48 of the second profile 44 which faces it, are parallel.
- the distance f between this second rectilinear portion 38a and the portion 38b of the rectilinear portion 48 of the second profile 44 may be greater than or equal to 2 mm and / or less than or equal to 10 mm, preferably less than or equal to 5 mm. mm.
- FIG. 5 further illustrates that the cross section (or geometrical section) of the aerodynamic tube 8 delimits a passage section S for the flow of air passing through the aerodynamic tube 8.
- This passage section S is here defined by the walls of the aerodynamic tube 8 and the segment extending in the alignment direction of the aerodynamic tubes 8 between the second profile 44 and the end of the end 51 of the inner lip 40b.
- This passage section may have an area greater than or equal to 150 mm 2 , preferably greater than or equal to 200 mm 2 , and / or less than or equal to 700 mm 2 , preferably less than or equal to 650 mm 2 .
- a passage section of the air flow in the aerodynamic tube 8 limits the pressure losses which would have the consequence of having to oversize the turbomachine used to obtain an air flow ejected by the desired opening 40.
- a large passage section induces a large size of the aerodynamic tube 8.
- a larger passage section may affect the passage section of the induced air flow between the aerodynamic tubes 8 , thus not making it possible to obtain a satisfactory total flow of air directed towards the heat-transfer tubes 4.
- each aerodynamic tube 8 is vis-à-vis screw of the front face 4f connecting the first 4a and second 4b flat walls of a heat pipe 4 corresponding. More particularly, the trailing edge 38 of each aerodynamic tube 8 is included in the volume defined by the first and second longitudinal plane walls 4a, 4b of the heat pipe 4 corresponding.
- the second rectilinear portion 38a of the first profile and the rectilinear portion 48 of the second profile 44 are respectively contained in the same plane as the first longitudinal plane wall 4a and the second longitudinal plane wall 4b of the heat pipe 4 corresponding.

- this distance f is greater than or equal to 2 mm and / or less than or equal to 10 mm, preferably less than or equal to 5 mm.
- the distance f between the second rectilinear portion 38a of the first profile 42 and the portion 38b of the rectilinear portion 48 of the second profile 44, which faces it, may, however, be less than the distance separating the first longitudinal wall and the second longitudinal wall of the heat transport tube vis-à-vis the aerodynamic tube 8 is disposed.
- Two heat transfer tubes 4 may be contained in the volume defined by the air passage defined by two aerodynamic tubes 8 neighbors. However, it can be envisaged that a single heat-transfer tube 4, or three or four heat-transfer tubes 4 are contained in this volume. Conversely, it can be envisaged that an aerodynamic tube 8 is disposed opposite each heat-carrying tube 4.
- the aerodynamic ducts 8 are substantially rectilinear, parallel to each other and aligned so as to form a row of aerodynamic tubes 8.
- the first and second profiles 42, 44 of each aerodynamic tube 8 are, according to these examples, symmetrical with respect to a plane CC, or rope plane, passing through the leading edge 37 and the trailing edge 38 of each aerodynamic tube 8.

- the peak speed of the air velocity profile in the vicinity of the profile tends to be reduced by departing from the opening 40 in the aerodynamic tube.
- An absence of peak reflects a homogeneous mixture of the air flow ejected by the opening 40 and the induced air flow. It is preferable that such a homogeneous mixture is made before the airflow reaches the aerodynamic tubes.
- a flow of air incident on the heat transfer tubes, heterogeneous does not allow optimal cooling of the heat pipes and induces greater pressure losses.
- the distance between the aerodynamic tubes and the heat transfer tubes is preferably contained to limit the size of the cooling module.
