- FIG. 8 it is in particular possible for the opening 60-1 of a module 100-1 to be closed, totally or partially, while the opening 60-2 of the other module 100-2 is left free, totally or partially.
- the covering bodies 64-1, 64-2 make it possible to direct the air flow created towards the turbomachine 28-1, 28-2 of the associated module 100-1, 100-2.
- the configuration where the covering bodies 64-1, 64-2 leave the openings 60-1, 60-2 of the two modules 100-1, 100-2 completely free, generally achieved while the turbomachines 28-1, 28 -2 are off allows to direct at least part of the air flow created for example by the speed of the vehicle, on which the cooling module 22 is mounted, through the openings 60-1, 60-2 in the frame 30, without going through the turbomachines 28-1, 28-2. This "diverts" the air flow from the turbomachines 28-1, 28-2.
- An intermediate configuration can allow part of the air flow to pass through the opening 60-1, 60-2 of a module 100-1, 100-2 of reduced size, another part of the air flow being guided towards the turbomachine 28-1, 28-2 of a module 100-1, 100-2.
- FIG. 9 illustrates a second example of a ventilation device 24, in which the two modules 100-1, 100-2 are arranged such that the air outlet 46-1 of the turbomachine 28-1 of a first module 100-1 is arranged opposite the guide portion 42-2 of the turbomachine 28-2 of the second module 100-2. This limits the risks that the air flows F1, F2 from the two turbomachines 28-1, 28-2 interfere with each other.
- FIG. 10 illustrates a third example of a ventilation device 24, in which the two modules 100-1, 100-2 are arranged such that the guide portion 42-1 of the turbomachine 28-1 of a first module 100-1 is arranged opposite the guide portion 42-2 of the turbomachine 28-2 of the second module 100-2.
- the two air outlets 46-1, 46-2 of the two turbomachines 28-1, 28-2 are oriented in opposite directions, such that the risks that the air flows F1, F2 from the two turbomachines 28-1, 28-2 disturb each other.
- the invention is not limited only to the examples described above. On the contrary, the invention is capable of numerous variants accessible to those skilled in the art.
- the body covering 64-1, 64-2 is in one piece.
- the covering body can be formed of blades interconnected by articulations of such kind that the blades can be pivoted with respect to each other.
- the covering body passes from the position of closing the opening 60-1, 60-2 to the position leaving the opening 60-1, 60-2 free, in being wrapped around a tree.
- the opening body can be retracted or folded up.
- the ventilation device 24 comprises two modules 100-1, 100-2.
- the ventilation device 24 can consist of a single module 100-1, 100-2 or more than two modules 100-1, 100-2.
