Definitions

• the present invention relates to a motor vehicle, which has a new implementation of its aerothermal module. It also relates to a new method of mounting on a motor vehicle of an aerothermal module with such a new implantation.
• radiator means, in the following text, a set of equipment for cooling the engine, such as a radiator and a motor fan (also referred to as “GMV” in the following text) , to which may be added a condenser, if the vehicle is equipped with an air conditioning, and a charge air cooler, if the vehicle is turbocharged.
• GMV motor fan
• This aerothermal module is located, conventionally, in front of the front block of the vehicle, between the shock beam and the powertrain (also referred to as "GMP" in the rest of the text), according to a layout called “ in facade ", the various elements of the aerothermal module being arranged substantially vertically against each other.
• This front layout has the disadvantage of requiring a relatively large carrier structure length between the center of the front wheel and the front end of the vehicle. This length has the consequence, on the one hand, to increase the overall length of the vehicle and, on the other hand, to increase the front overhang. Too long a length of this front overhang prejudices the "style", the aerodynamics, the mass and the cost of the vehicle, the turning circle between walls, and reduces the angle of attack, it that is to say the maximum inclination of the ascending slope that can approach the vehicle without damaging the bottom of the body.
• [ooo ⁇ ] To overcome one or more of these difficulties, it has already substantially changed the implementation of the aerothermal module, or at least one of the elements that constitute it.

• This module 1 is located above the GMP, general reference 8, in a space between the hood 10 of the vehicle and the GMP 8, more precisely in the space between the fictitious surface called "technical hood", shown by line 9 in Figure 1, and the surface of the GMP increased its deflection, said surface of the "GMP discussed", represented by the line 1 1 in Figure 1.
• hood is meant, in a conventional manner, the dummy surface, located under the lining of the hood, which delimits with the latter an exclusion zone, in which is excluded any implantation of a rigid component, in order to take into account the possible consequences of a pedestrian impact.
• the “technical hood” 9 is the design limit sufficiently far from the hood to be compatible with the pedestrian impact regulation.
• GMP discussed January 1 means the outer surface of the GMP increased its clearance space, the deflection being due mainly to the demands of the road.
• the new implementation of the aerothermal module 1 above the GMP 8 substantially reduces the distance between the GMP 8 and the shock beam, referenced 7 in the figures, at the front end of the vehicle and, accordingly, can reduce the front overhang of the vehicle, that is to say the distance between the front end of the vehicle and the center of the front wheel (not shown).

• the water ducts, coolant and degassing are adapted and allow to put the aerothermal module 1 in "after-sales" position (position B of Figure 4).
• the inclination of the frame 12 relative to the vertical is minimal, so as not to penalize the performance of the exchangers.
• the cooling equipment consisting of "hard” elements, is tangent to the technical hood 9 built from the style hood 10, itself consistent with the style and the criterion of low visibility.
• a sheath 16 fresh air supply (Figure 1), fixed on the front, allows to feed the cooling equipment with the appropriate air velocities.
• This sheath 16 is made of flexible material and, thanks to this flexibility, can be partially installed above the technical hood 9.

• the implementation described above of a motor vehicle aerothermal module has the advantage of allowing a gain in architecture performance of the front block of the vehicle. This yield essentially results in a sharp reduction in the distance between the impact beam 7 and the GMP 8, therefore a sharp reduction in the technical front overhang of the vehicle.
