Definitions
- the present invention relates to a set of tangential turbomachine cooling modules for the front face of an electric or hybrid motor vehicle.
- a cooling module (or heat exchange module) of a motor vehicle conventionally comprises at least one heat exchanger and a ventilation device adapted to generate an air flow in contact with the at least one heat exchanger.
- the ventilation device thus makes it possible, for example, to generate a flow of air in contact with the heat exchanger, when the vehicle is stationary or at low driving speed.
- the at least one heat exchanger is of substantially square or rectangular shape, the ventilation device then being a propeller fan whose diameter is substantially equal to the side of the square formed by the heat exchanger. heat.
- the heat exchanger is then placed opposite at least two cooling bays, formed in the front face of the motor vehicle body.
- a first cooling bay is located above the bumper while a second bay is located below the bumper.
- Such a configuration is preferred because the heat engine must also be supplied with air, the air intake of the engine being conventionally located in the passage of the air flow passing through the upper cooling bay.
- electric vehicles are preferably provided only with cooling bays located under the bumper, more preferably with a single cooling bay located under the bumper. Indeed, the electric motor does not need to be supplied with air. And the reduction in the number of cooling bays improves the aerodynamic characteristics of the electric vehicle. This also translates into better autonomy and a higher top speed of the motor vehicle.
- cooling bays also leads to a reduction in the surface area available for the passage of an air flow passing through the heat exchangers arranged downstream.
- cooling power requirements are different. In rapid battery charging, the cooling power requirements are high and it is therefore necessary to have a large exchange surface. In normal use of the batteries, the cooling power requirements are lower and therefore a smaller exchange surface may be suitable.
- the batteries are recharged quickly when stationary.
- a large exchange surface at the level of the cooling module and powerful means of ventilation are therefore necessary for good thermal management of the batteries.
- all of this exchange surface is not necessary for good thermal management of the latter. This generates an excess of air intake on the front face and thus reduces the aerodynamic characteristics of the electric or hybrid vehicle, which can reduce the range and top speed of the motor vehicle.
- the object of the present invention is therefore to remedy, at least partially, the drawbacks of the prior art and to propose an improved motor vehicle front end.
- the present invention therefore relates to a set of cooling modules for the front face of an electric or hybrid motor vehicle, said set of cooling modules comprising at least two cooling modules each comprising
- cooling modules intended to be connected to a cooling circuit, and a turbomachine, said cooling modules being juxtaposed so as to be crossed by separate air flows.
- the heat exchangers of the cooling modules are condensers connected to a refrigerant fluid circulation loop configured for the thermal management of the batteries of the electric or hybrid vehicle.
- the heat exchangers of the cooling modules are connected in parallel to each other within the refrigerant fluid circulation loop.
- the heat exchangers of the cooling modules are connected in series within the refrigerant circulation loop.
- each cooling module comprises an individual motor, configured to allow the rotation of its turbine engine.
- the set of cooling modules comprises a common motor configured to allow the simultaneous rotation of the turbomachines of each cooling module.
- the turbomachines (30, 30′, 30′′) of the juxtaposed cooling modules are connected to each other by a connection and drive shaft.
- the connecting and drive shaft comprises an articulation.
- the cooling modules each comprise a dedicated shutter device.
- the set of cooling modules comprises a main cooling module and at least one secondary cooling module of smaller size than the main cooling module.
- the present invention also relates to a front face of an electric and/or hybrid motor vehicle comprising a set of cooling modules as described previously.

- the following achievements are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference is to the same embodiment, or that the features apply only to a single embodiment. Single features of different embodiments may also be combined and/or interchanged to provide other embodiments.
- first element or second element as well as first parameter and second parameter or else first criterion and second criterion, etc.
- first criterion and second criterion etc.
- it is a simple indexing to differentiate and name elements or parameters or criteria that are close, but not identical. This indexing does not imply a priority of one element, parameter or criterion over another and it is easy to interchange such denominations without departing from the scope of the present description. Nor does this indexing imply an order in time, for example, to assess such and such a criterion.
- placed upstream means that one element is placed before another with respect to the direction of circulation of an air flow.
- placed downstream means that one element is placed after another in relation to the direction of circulation of the air flow.
- an XYZ trihedron is represented in order to define the orientation of the various elements from each other.
- a first direction, denoted X corresponds to a longitudinal direction of the vehicle. It also corresponds to the direction of travel of the vehicle.
- a second direction, denoted Y is a lateral or transverse direction.
- a third direction, denoted Z is vertical. The directions, X, Y, Z are orthogonal two by two.
- a main cooling module 22 in a functional position, that is to say when it is arranged within a motor vehicle, more precisely at the level of the front face of said motor vehicle .
- FIG. 1 schematically illustrates the front part of an electric or hybrid motor vehicle 10 which may comprise an electric motor 12.
- the vehicle 10 notably comprises a body 14 and a bumper 16 carried by a chassis (not shown) of the vehicle automobile 10.
- the body 14 defines a cooling bay 18, that is to say an opening through the body 14.
- the cooling bay 18 is unique here.
- This cooling bay 18 is preferably located in the lower part of the front face 14a of the bodywork 14. In the example illustrated, the bay 18 is located under the bumper 16.
- a grid 20 can be arranged in the cooling bay 18 to prevent projectiles from passing through the cooling bay 18.
- At least two cooling modules 22, 22', 22” are arranged opposite the cooling bay 18.
- the front face of the electric or hybrid vehicle comprises a set of cooling modules 22, 22', 22” juxtaposed and visible in more detail in FIGS. 4 to 6.
- This set of cooling modules 22, 22', 22” comprises a main cooling module 22 and at least one secondary cooling module 22', 22”.
- the grid 20 is used in particular to protect the various cooling modules 22, 22′, 22′′.
- the main cooling module 22 is intended to be traversed by an air flow F parallel to the direction X and going from the front to the rear of the vehicle 10.
- the main cooling module 22 comprises a set of heat exchangers 23 through which the air flow F passes.
- the main cooling module 22 can essentially comprise a casing or shroud 40 forming an internal channel between two opposite ends 40a, 40b and inside which the set of heat exchangers 23 is arranged.
- This internal channel is preferably oriented parallel to the direction X so that the upstream end 40a is oriented towards the front of the vehicle 10 opposite the cooling bay 18 and so that the downstream end 40b is oriented towards the rear of the vehicle 10.
- the main cooling module 22 may also comprise a first manifold box 41 disposed downstream of the set of heat exchangers 23 in the direction of circulation of the air flow.
- This first collector box 41 comprises an outlet 45 for the air flow F.
- This first collector box 41 thus makes it possible to recover the flow of air passing through the set of heat exchangers 23 and to direct this flow of air towards the outlet 45.
- the first collector box 41 can be made in one piece with the fairing 40 or else be an attached part fixed to the downstream end 40b of said fairing 40.
- the main cooling module 22 also comprises at least one tangential fan, also called tangential turbomachine 30, configured so as to generate the air flow F to the set of heat exchangers 23.
- the tangential turbomachine 30 comprises a rotor or turbine (or tangential propeller).
- the turbine has a substantially cylindrical shape.
- the turbine advantageously comprises several stages of blades (or blades).
- the turbine is rotatably mounted around an axis of rotation A, by example parallel to the direction Y.
- the diameter of the turbine is for example between 35 mm and 200 mm to limit its size.
- the tangential turbomachine 30 is thus compact.
- the use of such a tangential turbomachine 30 allows in particular that the air flow F is equal over the entire width of the set of heat exchangers 23.
- such a tangential turbomachine 30 saves space by compared to conventional fans.
- the tangential turbomachine 30 can also comprise a motor 31 (visible in FIG. 2) configured to set the turbine in rotation.
- the motor 31 is for example adapted to drive the turbine in rotation, at a speed of between 200 revolutions/min and 14,000 revolutions/min. This makes it possible in particular to limit the noise generated by the tangential turbomachine 30.
- the tangential turbomachine 30 is preferably arranged in the first manifold housing 4L.
- the tangential turbomachine 30 is then configured to suck in air in order to generate the air flow F passing through the set of heat exchangers 23.
- the first housing collector 41 then forms a volute in the center of which is arranged the turbine and whose air evacuation at the outlet 45 of the first collector box 41 allows the outlet of the air flow F.
- the tangential turbomachine 30 is in a high position, in particular in the upper third of the first manifold housing 41, preferably in the upper quarter of the first manifold housing 4L. This makes it possible in particular to protect the turbomachine tangential in the event of submersion and/or to limit the size of the main cooling module 22 in its lower part.
- the tangential turbomachine 30 is in a low position, in particular in the lower third of the first collector box 4L. This would make it possible to limit the size of the main cooling module 22 in its upper part.
- the tangential turbomachine 30 can be in a middle position, in particular in the middle third of the height of the first manifold box 41, for example for reasons of integration of the cooling module 22 in its environment.
- the tangential turbomachine 30 operates in suction mode, that is to say it sucks in the ambient air so that it passes through the set of heat exchangers 23
- the tangential turbomachine 30 can operate by blowing, blowing air towards the set of heat exchangers 23.
- the tangential turbomachine 30 will be placed upstream of the set of heat exchangers 23.
- the main cooling module 22 can also include a second manifold box 42 arranged upstream of the set of heat exchangers 23.
- This second manifold box 42 includes an inlet 42a for the flow of air F coming from outside the vehicle 10.
- the inlet 42a may in particular be arranged opposite the cooling bay 18.
- This inlet 42a may also include the protective grid 20.
- the second collector box 42 can be made in one piece with the fairing 40 or else be an attached part fixed to the upstream end 40a of said fairing 40.
- the center 42a of the second collector box 42 may comprise a front face shutter device (not shown) movable between a first so-called open position and a second so-called closed position.
- This front face closing device is configured in particular to allow the air flow F coming from F outside the vehicle 10 to pass through said inlet 42a in its open position and to close said air flow inlet 42a in its shutter position.
- the front face closure device can be in different forms, such as for example in the form of a plurality of flaps mounted to pivot between an open position and a closed position. These flaps are preferably mounted parallel to the Y direction. Nevertheless, it is entirely possible to imagine other configurations such as, for example, flaps mounted parallel to the Z direction. Other types of shutters such as butterfly shutters are quite possible.
- the set of heat exchangers 23 more particularly comprises a plurality of heat exchangers 24, 26, 28 arranged one behind the other so as to be crossed by the same flow of air F.
- the main cooling module 22 here comprises three heat exchangers 24, 26 and 28. Each of its heat exchangers can be dedicated to the evacuation of heat in order to cool elements or components within the electric vehicle.
- the set of heat exchangers 23 of the main cooling module 22 notably comprises a heat exchanger 28 connected to a cooling circuit. More specifically, this heat exchanger 28 can be a condenser and be connected to a refrigerant fluid circulation loop C configured to allow thermal management of the motor vehicle batteries. As shown in FIG. 3, the refrigerant circulation loop C may comprise, in the direction of circulation of the refrigerant fluid, a compressor 3, the condenser 28, a first expansion device 4 and a heat exchange interface 5 with The batteries. This heat exchange interface 5 can be in direct contact with the batteries or else allow heat energy exchanges with another circulation loop (not shown) for indirect management of the temperature of the batteries.
- the refrigerant circulation loop C can for example be an air conditioning loop and comprise, in parallel with the first expansion device 4 and the heat exchange interface 5, a second expansion device 6 and an evaporator 7 configured to cooling a flow of air to the passenger compartment.
- Other more complex architectures can quite be imagined for this refrigerant circulation loop C.
- the set of heat exchangers 23 of the main cooling module 22 may include additional heat exchangers 24, 26.
- the main cooling module 22 comprises two additional heat exchangers 24 and 26. It is however entirely possible to imagine examples with a single additional heat exchanger 24.
- These additional heat exchangers 24, 26 can also be heat exchangers dedicated to the evacuation of heat in order to cool elements or components within the electric vehicle.
- one of these additional heat exchangers 24 can be a radiator connected to the heat transfer fluid circulation loop B.
- This heat transfer fluid circulation loop B can in particular be configured to allow the thermal management of electrical elements such as the power electronics and/or the electric motor of the motor vehicle.
- This heat transfer fluid circulation loop B can thus comprise, in addition to the radiator 24, a pump 8 and a heat exchange interface 9 with electrical elements such as the power electronics and/or the electric motor of the motor vehicle.
- this radiator 24 is more particularly arranged the furthest downstream of the air flow F within the cooling module 22, in particular downstream of the condenser 28. Indeed, because this radiator 24 allows the thermal management of electrical elements such as the power electronics and/or the electric motor of the motor vehicle, the cooling requirements are lower than for other elements such as the batteries. The air flow F passing through the radiator 24 therefore has no need to be as "cool” as possible, unlike the air flow F passing through the condenser 28.
- the set of heat exchangers 23 comprises only two heat exchangers 28 and 24.
- the third heat exchanger 26 is not shown.
- the latter can be optional and for example be connected to a heat transfer fluid loop dedicated to cooling the electric motor.
- the set of cooling modules 22, 22', 22" includes a primary cooling module 22 and at least one secondary cooling module 22', 22".
- the 22, 22’, 22” cooling modules are juxtaposed so as to be crossed by distinct air flows F.
- the fact of having different cooling modules 22, 22', 22" juxtaposed makes it possible to control the air flows F passing through each of the cooling modules 22, 22', 22" and thus to control the exchange surfaces necessary for the different thermal managements.
- each cooling module 22, 22′ and 22′′ may in particular each comprise a dedicated shutter device (not shown).
- the set of cooling modules 22, 22', 22" more specifically comprises a main cooling module 22 and two secondary cooling modules 22' and 22".
- the secondary cooling modules 22' and 22" are here arranged on either side of the main cooling module 22 in the transverse direction Y.
- the secondary cooling modules 22', 22" are structurally similar to the main cooling module 22.
- the secondary cooling modules 22', 22" also comprise at least one heat exchanger 28', 28" intended to be connected to a circuit cooler and a 30', 30” turbomachine. This makes it possible to control the exchange surface allocated to the thermal management of different elements and thus to adapt it to the need for cooling power, for example between normal use of the batteries and rapid recharging of the latter.
- the heat exchangers 28', 28” of the secondary cooling modules 22', 22” can also be condensers connected to the refrigerant fluid circulation loop C configured for the thermal management of the batteries of the electric or hybrid vehicle.
- the heat exchangers 28, 28', 28" of the cooling modules 22, 22', 22" are connected in series within the refrigerant circulation loop C.
- the heat exchangers 28' and 28” of the secondary cooling modules 22' and 22” can in particular be arranged downstream of the heat exchanger 28 of the main cooling module 22 within the circulation loop C of the refrigerant fluid.
- the refrigerant circulation loop C can also include a bypass (not shown) allowing the bypass of the heat exchangers 28' and 28" of the secondary cooling modules 22', 22" in order to increase or decrease the exchange surface. between the air flow F and the refrigerant fluid.
- H is thus possible to increase or decrease the exchange surface between the air flow F and the cooling fluid by controlling, for example, the air flow passing through the various cooling modules 22, 22', 22”, in particular the secondary cooling modules 22', 22” by means of front face closing devices or by controlling the circulation or not of the refrigerant fluid in the heat exchangers 28' and 28” of the secondary cooling modules 22', 22” through derivation.
- the heat exchangers 28, 28', 28" of the cooling modules 22, 22', 22" can be connected in parallel with each other. others within the refrigerant circulation loop C.
- the secondary cooling modules 22', 22” can in particular be smaller in size than the main cooling module 22. Indeed, the main cooling module 22 and its heat exchanger 28 remain the main exchange surface and therefore the main source of cooling power while the secondary cooling modules 22', 22” and their heat exchangers 28', 28” are additional exchange surfaces used in certain special cases, for example during rapid recharging of the batteries.
- each cooling module 22, 22', 22" comprises an individual motor 31, 31', 31", configured to allow the rotation of its 30, 30', 30” turbomachine. It is thus possible to generate an air flow F independently for each cooling module 22, 22', 22” by means of their individual turbomachine 30, 30', 30”.
- the set of cooling modules 22, 22', 22" may include a common motor 31 configured to allow the simultaneous rotation of the turbomachines 30, 30', 30" of each cooling module 22, 22', 22”.
- turbomachines 30, 30', 30" of the juxtaposed cooling modules 22, 22', 22" can be connected to each other by a connecting and drive shaft 32 as illustrated in FIG. 5 More specifically, one end of a turbomachine 30, 30', 30" is connected to one end of another turbomachine 30, 30', 30" facing it by a connecting and drive shaft 32.
- the connecting and drive shaft 32 may also include an articulation 33.
- This articulation 33 may for example be a universal joint. This thus makes it possible to modify the angle of the various cooling modules 22, 22′, 22′′ relative to each other in order, for example, to match the rounded shape of the front face of the motor vehicle.
