    Brief description of the drawings
    The objects, objects and features of the present invention, as well as its advantages, will appear more clearly on reading the present description of a preferred embodiment according to the invention, with reference to the drawings, in which: FIG. 1 shows an exploded view of a cooling system according to one embodiment of the invention.
    Detailed Description
    The purpose of the following description is to explain the invention in a sufficiently clear and complete manner, in particular by means of examples, but in no case should it be considered as limiting the scope of protection to the embodiments. described below.
    In the present description, the term "cap" is used which refers to the armature for a fan. The cap, also known by its English name "shroud" is a structure adapted to position the fan and comprises an opening which coincides substantially with the ends of the rotating elements of said fan.
    In general, within a motor vehicle, a front-end module is a structural element intended to contain a plurality of devices necessary for the optimal operation of said motor vehicle, such as projectors and a cooling system. At the end of the production of a front-end module of a motor vehicle, it can be assembled directly on said motor vehicle, in particular with elements of the chassis of said vehicle, such as longitudinal members. The front-end module can also be installed on the motor vehicle by assembling with a bumper or a front bumper.
    In known manner, the front-end module of a motor vehicle comprises a support for receiving the device necessary for the operation of said vehicle and a bumper beam for protecting said device in the event of a frontal collision.
    As a general rule, the support of the front-end module comprises a lower cross-member, lateral posts for said lower cross-member, an upper cross-member at the top of the lateral posts and, optionally, reinforcement arms fixed to the ends of the upper rail and / or lateral amounts. Such a support of the front panel module may comprise different pieces fixed together. This is for example the case when the support of the front panel module is composed of steel elements.
    Alternatively, the support of the front panel module can be obtained using a suitable plastic material, made by a molding process. It is also known to use front-end module supports comprising two materials in which the basic structure comprises plastic and in which reinforcements comprise metallic materials.
    FIG. 1 represents an exploded view of the cooling system 1 of a motor vehicle according to one embodiment of the invention. The cooling system 1 comprises a support 10 of a front-end module forming the main element and intended to receive and fix the ancillary elements of said cooling system 1 according to the invention. The support comprises an upper crossmember 21, a lower crossmember 22 and two lateral uprights 23, 24. The support 10 is adapted to receive and to allow the fixing of elements necessary for the cooling system 1. For illustrative reasons, some elements are shown in FIG. 1, such as the condenser 11, an upper moving shutter structure 12, a lower movable shutter structure 13.
    The cooling system 1 comprises an air / air or air / water heat exchanger 14 within which a heat exchange takes place between a first fluid to be cooled and a flow of air passing through the cooling system 1 according to FIG. .
    The cooling system 1 according to Figure 1 also comprises a radiator 15 and a fan 16, both positioned on a cap 17. Furthermore, the cooling system 1 may have sealing elements such as a cover 18.
    According to a non-illustrated embodiment, it is possible for the fan 16 to be positioned on the cap 17 and for the radiator 15 to be fixed directly on the support 10.
    The cooling system 1 as shown in Figure 1 allows the attachment of the various elements 10 to 18 on the support 10 of the front panel module to form together an encapsulated cooling system. The cooling system 1 is thus provided, thanks to the assembly of the elements 11 to 18, of a box comprising a sealed structure for encapsulating the entire cooling system 1 between an air inlet, formed by the upper and lower movable shutter structures 12, 13, and the air outlet, formed by the fan 16. The effect of the measures described above is that the cooling system 1 according to Figure 1 is provided with a housing or waterproof envelope providing a sealed structure to prevent air leakage between the inlet and the air outlet of said cooling system 1. The housing or the sealed structure is formed by the various elements of the system of 1 which are adapted to form together an envelope or waterproof structure. As a result, all the air entering the cooling system 1 is used for heat exchange, thus optimizing the cooling of a fluid.
    According to a first technical effect, the use of penetrating air within the cooling system for heat exchange is optimized, which makes it possible to use a smaller flow of air to cool a quantity of fluid. determined.
    According to a second technical effect lies in the fact that the various elements used within the cooling system 1 according to the invention can be undersized compared to cooling systems that do not include the type of housing provided with a sealed structure to prevent leaks.
    In addition, within the cooling system 1 as shown in Figure 1, the support 10 of the front panel module is integral with said cooling system 1 according to the invention. In other words, it avoids a construction comprising, firstly, the assembly of a cooling system and, in a second step, the fixing of said system on the front panel module of the motor vehicle.
    The cooling system 1 as shown in FIG. 1 is adapted to allow the various elements 11 to 18 to be assembled on the front-face module 10 and thus to obtain the cooling system 1 according to the invention, in which the support 10 front face forms part of the sealed structure around said cooling system 1.
    The cooling system 1 as shown in FIG. 1 makes it possible to ensure that the use of the material intended to obtain the support 10 of the front-face module is optimized in that said support offers a dual function making it possible to on the one hand, fixing said front panel module 10 inside a motor vehicle and, on the other hand, using said front panel module 10 to create a structure or sealed envelope around a cooling system 1 of said motor vehicle.
