DEVICE FOR CHANNELING AND MANAGING THE FLOW OF THE COOLING AIR FLOW OF A VEHICLE AND SUPPORTING ONE OR MORE WIND POWER GENERATORS.

FR 3 063 686 - A1

The invention relates to a device making it possible to improve the efficiency of the air flow entering through the front part of a motor-powered four-wheeled vehicle (private car, leisure or transport vehicle) to improve the performance of the latter in terms of consumption, emission, electricity production, speed and stability.

It consists of a technical structure on the front of the vehicle in the form of a rigid hollow shell, made in one or more parts, adapted to each model of vehicle, positioned and fixed under the hood, between and against all or part of the air inlets located on the front of the vehicle (upstream) and all or part of the front of one or more of its heat exchangers (downstream). Constitutively, this hull has openings to channel and manage the air flow circulating from upstream to downstream and has internal locations to support wind turbines to stir the air flow while generating electricity. This shell can also have openings with hinged or non-articulated baffles, openings for positioning sensors, internal air baffles and electronic and software systems for managing the active elements present.

The device according to the invention is particularly intended for the automotive sector to improve vehicle performance, user comfort and the services rendered.

The present invention relates to a device for channeling and managing the flow of the cooling air flow entering through the front part of a motor-powered vehicle rolling on four wheels (private car, leisure vehicle, transport vehicle for goods or people), located under its hood, between all or part of the air inlets and all or part of its heat exchangers (radiator, condenser ...).

When on the move, the coefficient of cooling drag of a four-wheel motorized powered vehicle should not be overlooked. It represents for example between 5 and 10% of its total aerodynamic drag (Cx) in the case of an automobile. Managing the air flow entering upstream under the hood from the front of a moving vehicle is advantageous for improving its performance (consumption, emissions, electricity production, speed, and stability).

The management of this air flow entering from the front of a vehicle is traditionally carried out using:

the shield geometry, the number, the geometry and the location of the front air intakes, the geometry of the grilles or deflectors located at the air intakes of the front shield, the grille or the spoilers, the location of the exchangers the geometry of the elements under the hood.

simple and passive air guide structures on the front

However, a) a part of the incoming air flow does not reach the heat exchangers, passing on either side around it, and b) the other part of the incoming air flow remains distributed in a nonuniform manner and generally in overpressure on the front face of these same heat exchangers; this continuing to impact the efficiency of the incoming air flow and therefore the performance of the vehicle (consumption, emissions, electricity production, speed, and stability).

The device according to the invention overcomes these drawbacks. According to a first characteristic, the device comprises a technical structure of the vehicle front face in the form of a rigid hollow shell, manufactured in one or more parts, adapted to each vehicle model, positioned and fixed specifically according to the vehicle model under the hood, between and against the air intake (s) located on the front of the vehicle (upstream) and the front face of one or more of its heat exchangers (downstream). Constitutively, this hull has openings to channel and manage the incoming and outgoing air flow from upstream to downstream and has one or more internal locations to support fixed or removable wind power generators designed to stir the flow air entering and flowing from upstream to downstream while generating electricity.

According to particular embodiments:

) the shell may constitute all or part of the front face, shield or grille of the vehicle

-22) the openings can be aligned and adjusted opposite all or part of the air inlets as well as opposite all or part of the front face of one or more heat exchangers of the vehicle

3) the hull can support one or more fixed, removable and / or articulated internal air deflectors.

4) openings can have one or more flaps, articulated or not, which can serve as air deflectors to manage the volume, the flow and / or the speed of the incoming and outgoing air flow from upstream to downstream

5) openings can be used to position any type of sensor inside the hull to characterize the circulating air flow (speed, pressure, composition ...)

6) electronic systems and software can be added to manage the active elements present: wind power generators, deflectors, shutters and sensors.

The accompanying drawing (Figure 1) illustrates the device of the invention.

With reference to these drawings, the device comprises a technical structure of the vehicle front face in the form of a rigid hollow shell (1), manufactured in one or more parts, adapted to each vehicle model, positioned and fixed specifically according to the model. under the hood, between and against the air inlet (s) located on the front of the vehicle (upstream) and the front face of one or more of its heat exchangers (downstream). Constitutively, this hull (1) has openings of two types to channel and manage the incoming and outgoing air flow from upstream to downstream:

constituent openings: upstream openings (2) which can align and adjust facing all or part of the air inlets, and downstream openings (3) which can align and adjust facing all or part of the front face of one or more heat exchangers;

optional openings: management openings (7) having one or more flaps (8), articulated or not, which can serve as a deflector for managing the volume, the flow and / or speed of the incoming air flow, and measurement openings (9) for positioning any type of sensor (10) inside the shell (1) to characterize the flow of circulating air (speed, pressure, composition, etc.).

This shell (1) also has one or more internal locations (4), located between the upstream and downstream openings (2,3), to support one or more fixed or removable wind power generators (5) placed in the shell to mix the incoming and outgoing air flow from upstream to downstream, while generating electricity.

Still with reference to the drawings, the device can support one or more internal, fixed, removable and / or articulated air deflectors (6), as well as have electronic systems and software (11) to manage the active elements present: electric generators wind turbines (5), deflectors (6), shutters (8) and sensors (10).

-375 The device according to the invention is particularly intended for the automotive sector to improve vehicle performance, user comfort and the services rendered. It can interest public or private companies with fleets of vehicles, companies transporting goods or people,

- individuals, car and equipment manufacturers, and wind turbine manufacturers.
