Definitions
- the present invention relates to a cooling module for an electric or hybrid motor vehicle, with a tangential turbomachine.
- 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 heat exchanger is then placed in a compartment 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.
- this compartment may be more or less cluttered and obstacles may be present at the rear of the cooling module and hinder the evacuation of the air flow passing through it. This is especially the case when the airflow is generated by the ventilation device. It is therefore necessary to increase the size and/or the power of this ventilation device so that the air flow is sufficient for the heat exchanges to take place correctly at the level of the heat exchanger(s). This solution is not the most optimal because it consumes energy and can affect the range of the electric or hybrid vehicle.
- the object of the present invention is therefore to at least partially remedy the drawbacks of the prior art and to propose an improved cooling module allowing optimal performance while limiting its energy consumption.
- the present invention therefore relates to a cooling module for an electric or hybrid motor vehicle, said cooling module being intended to be traversed by a flow of air and comprising:
- a fairing forming an internal channel through which the air flow passes between an upstream end and a downstream end opposite to each other, said fairing comprising at least one heat exchanger, - a first manifold housing disposed downstream of the fairing in a longitudinal direction of the cooling module extending from the front to the rear of said cooling module, said first manifold housing comprising a tangential turbomachine configured so as to generate the air flow , said tangential turbomachine comprising a volute comprising an airflow outlet, the volute comprising an outer wall movable between a first extreme position in which the airflow outlet has a first orientation and a second extreme position in which the outlet of the airflow has a second orientation distinct from the first orientation.
- the outer wall is sliding.
- the cooling module comprises a winding shaft around which the outer wall winds, said winding shaft being fixed to the end of the outer wall opposite to its end forming the outlet.
- the winding axis is motorized.
- the cooling module comprises side rails for guiding the outer wall.
- the first orientation of the airflow outlet is perpendicular to the longitudinal direction of the cooling module.
- the second orientation of the airflow outlet is opposite to the first orientation of said outlet with respect to the longitudinal direction of the module cooling.
- the outlet of the air flow is oriented in an intermediate orientation between the first and the second direction.
- the outer wall of the volute comprises a succession of articulated and mutually parallel slats.
- the external wall of the volute is a semi-rigid canvas impermeable to air.
- FIG. 1 shows a schematic representation of the front of a motor vehicle in side view
- Figure 2 shows a schematic representation in perspective and in partial section of the front of a motor vehicle and a cooling module
- Figure 3 shows a schematic sectional representation of a first collector an outer wall according to a first extreme position
- Figure 4 shows a schematic sectional representation of a first manifold an outer wall in an intermediate position
- Figure 5 shows a schematic sectional representation of a first collector an outer wall according to a second extreme position.
- 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 such denominations can easily be interchanged 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.
- upstream means that one element is placed before another with respect to the direction of circulation of an air flow.
- downstream we mean that one element is placed after another in relation to the direction of circulation of a flow or a fluid.
- an XYZ trihedron is shown in order to define the orientation of the various elements relative to each other.
- a first direction, denoted X corresponds to a longitudinal direction of the vehicle. It also corresponds to the inverse of the direction vehicle progress.
- 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.
- cooling module according to the present invention is illustrated in a functional position, that is to say when it is arranged within a 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 cooling bay 18 is located under the bumper 16.
- a grille 20 can be arranged in the cooling bay 18 to prevent projectiles from passing through the cooling bay 18.
- a cooling module 22 is arranged opposite the cooling bay 18.
- the grid 20 makes it possible in particular to protect this cooling module 22.
- the cooling module 22 is intended to be crossed by an air flow L parallel to the direction X and going from the front to the rear of the vehicle 10.
- This direction X corresponds more particularly to a longitudinal direction X running from the front to the rear of the cooling module 22.
- an element is referred to as "upstream” or “downstream” according to the longitudinal direction X of the cooling module 22, an element which is respectively arranged more forwards or backwards than another element.
- the front corresponds to the front of the motor vehicle 10 in the assembled state or else the face of the cooling module 22 via which the air flow L is intended to enter the cooling module 22. to him at the rear of the motor vehicle 10 or else to the face of the cooling module 22 through which the air flow L is intended to come out of the cooling module 22.
- the cooling module 22 essentially comprises a casing or shroud 40 forming an internal channel between an upstream end 40a and a downstream end 40b opposite each other. Inside said fairing 40 is arranged at least one heat exchanger 24, 26, 28. This internal channel is preferably oriented parallel in the longitudinal direction X so that the upstream end 40a is oriented towards the front of the vehicle 10 facing the cooling bay 18 and so that the downstream end 40b is oriented towards the rear of the vehicle 10.
- FIG. 2 the cooling module 22 comprises three heat exchangers 24, 26, 28 grouped together within a set of heat exchangers 23. It could however comprise more or less depending on the desired configuration.
- a first heat exchanger 24 can for example be configured to release heat energy from the air flow F.
- This first heat exchanger 24 can more particularly be a condenser connected to a cooling circuit (not shown), for example in order to cool the batteries of the vehicle 10.
- This cooling circuit can for example be an air conditioning circuit able to cool the batteries as well as an internal air flow intended for the passenger compartment of the motor vehicle.
- a second heat exchanger 26 can also be configured to release heat energy into the air flow F.
- This second heat exchanger 26 can more particularly be a radiator connected to a thermal management circuit (not shown) of electrical elements such as the electric motor 12.
- the first heat exchanger 24 generally being a condenser of an air conditioning circuit, the latter needs the air flow F to be as "cool" as possible in air conditioning mode.
- the second heat exchanger 26 is preferably arranged downstream of the first heat exchanger 24 in the longitudinal direction X of the cooling module 22. It is nevertheless quite possible to imagine that the second heat exchanger 26 is arranged upstream of the first heat exchanger 24.
- the third heat exchanger 28 can also be configured to release heat energy into the airflow.
- This third heat exchanger 28 may more particularly be a radiator connected to a thermal management circuit (not shown), which may be separate from that connected to the second heat exchanger 26, for electrical elements such as power electronics. It is also quite possible to imagine that the second 26 and the third 28 heat exchanger are connected to the same thermal management circuit, for example connected in parallel with each other.
- the second heat exchanger 26 is arranged downstream of the first heat exchanger 24 while the third heat exchanger 28 is arranged upstream of the first heat exchanger 24.
- Other configurations can nevertheless be envisaged, such as for example the second 26 and third 28 heat exchangers both arranged downstream or upstream of the first heat exchanger 24.
- each of the heat exchangers 24, 26, 28 has a generally parallelepipedal shape determined by a length, a thickness and a height.
- the length extends along the Y direction, the thickness along the X direction and the height in the Z direction. vertical Z and the lateral direction Y.
- This general plane is preferably perpendicular to the longitudinal direction X of the cooling module 22.
- the cooling module 22 also comprises a first manifold box 41 arranged 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 F passing through the set of heat exchangers 23 and to direct this air flow F to 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 tangential turbomachine 30 comprises a rotor or turbine 32 (or tangential propeller).
- the turbine 32 has a substantially cylindrical shape.
- the turbine 32 advantageously comprises several stages of blades (or blades).
- the turbine 32 is rotatably mounted around an axis of rotation A, for example parallel to the direction Y as illustrated in FIG. 2.
- the diameter of the turbine 32 is for example between 35 mm and 200 mm to limit its size.
- the turbomachine 30 is thus compact.
- the tangential turbomachine 30 can also comprise a motor 31 (visible in FIG. 2) configured to set the turbine 32 in rotation.
- the motor 31 is for example adapted to drive the turbine 32 in rotation, at a speed of between 200 rpm and 14,000 rpm. This makes it possible in particular to limit the noise generated by the tangential turbomachine 30.
- the tangential turbomachine 30 is arranged in the first manifold housing 4L
- the tangential turbomachine 30 is configured to suck in air in order to generate the air flow F passing through the set of heat exchangers 23.
- the turbomachine tangential 30 comprises more precisely a volute 44, formed by the first manifold housing 41 and at the center of which is arranged the turbine 32.
- the air evacuation of the volute 44 corresponds to the outlet 45 of the air flow F of the first manifold housing 41.
- 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 41. This makes it possible in particular to protect the tangential turbomachine 30 in the event of submersion and/or to limit the size of the cooling module 22 in its lower part.
- the outlet 45 of the air flow F is preferably oriented towards the lower part of the cooling module 22.
- the tangential turbomachine 30 is in a low position, in particular in the lower third of the first manifold housing 41. This would limit the size of the cooling module 22 in its upper part.
- the outlet 45 of the air flow will preferably be oriented towards the upper part of the cooling module 22
- upper and lower is meant here an orientation in the direction Z.
- a so-called upper element will be closer to the roof of the vehicle 10 and a so-called lower element will be closer to the ground.
- the first collector box 41 comprises, arranged facing the downstream end 40b of the fairing 40, a guide wall 46 of the flow of air F towards the outlet 45.
- This guide wall 46 makes more particularly the junction with an upstream edge 451 of the outlet 45 of the air flow F.
- upstream edge 451 we mean here the edge of the outlet 45 the closer to the downstream end 40b of the fairing 40.
- the guide wall 46 forms an angle ⁇ with a first plane PI perpendicular to the longitudinal direction X of the cooling module 22.
- This angle ⁇ is more particularly between 0° and a maximum angle of 25°, preferably 23°. If the angle a is 0° then the guide wall 46 coincides with the perpendicular PI to the longitudinal direction X of the cooling module 22.
- the maximum angle of 25° corresponds to the angle a' d a second plane of maximum inclination P2 (visible in FIGS. 3 to 5) with the first plane P1.
- the guide wall 46 is inclined and the angle a is between 5 and 25° with respect to the first plan pl.
- This second plane of maximum inclination P2 more precisely connects the upstream edge 451 of the outlet 45 and a downstream end edge 230 of F at least one heat exchanger 24, 26, 28.
- downstream end edge 230 is meant here the edge of a heat exchanger 24, 26, 28 closest to the downstream end 40b of the fairing 40.
- the downstream end edge 230 taken into consideration is the downstream end edge 230 of the most downstream heat exchanger, here the second heat exchanger 26.
- the end edge downstream 230 is arranged opposite the outlet 45 of the air flow F.
- the edge downstream end edge 230 is a lower end edge of the heat exchanger 26. Conversely, if the outlet 45 is oriented towards the upper part of the cooling module 22, the downstream end edge 230 will be an edge of upper end of the heat exchanger 26.
- the guide wall 46 forms an angle a comprised between 0° and 25° and more particularly when it is inclined at an angle a comprised between 0° and 25° allows better circulation of the air flow F within of the first manifold box 41 and limits the loss of charges.
- the volute 44 has an outer wall 440 movable.
- This outer wall 440 is more particularly movable between a first extreme position (illustrated in FIG. 3) in which the outlet 45 of the air flow F has a first orientation and a second extreme position (illustrated in FIG. 5) in which the outlet 45 of the air flow F has a second orientation distinct from the first orientation.
- the outer wall 440 can in particular be sliding.
- the cooling module 22 may comprise side rails 442 for guiding the outer wall 440. These side rails may in particular be arranged on the inner face of the side walls 443. These side walls 443 are more particularly perpendicular to the axis of rotation A of the turbine 32.
- the outer wall 440 of the volute 44 may for example comprise a succession of articulated and parallel slats to each other so as to form a semi-rigid curtain.
- the external wall 440 of volute 44 can also be, for example, a semi-rigid canvas that is impermeable to air.
- the cooling module 22 may include a winding axis 441 around which the outer wall 440 winds.
- This winding shaft 441 being fixed to the end of the outer wall 440 opposite its end forming the outlet 45.
- the winding axis 441 can more particularly be motorized. Thus, it is possible to adjust the position of the outer wall 440 by controlling the number as well as the direction of rotation of the winding axis 441 as required.
- Figure 3 shows an example in which the outer wall 440 is in its first extreme position.
- the first orientation of the outlet 45 of the air flow F is then perpendicular to the longitudinal direction X of the cooling module 22.
- this first orientation of the outlet 45 is thus downwards, i.e. that is to say facing the ground in the mounted state in the motor vehicle.
- Figure 4 shows an example in which the outer wall 440 is in an intermediate position located between its first and its second extreme position.
- the outlet 45 of the air flow F is then oriented in an intermediate orientation between the first and the second orientation.
- This intermediate orientation is here also oriented downwards as for the first orientation of the outlet 45 illustrated in FIG. 3.
- the angle here is not perpendicular with the longitudinal direction X of the cooling module 22.
- This angle is here less pronounced and can for example be of the order of 5 to 45° with respect to the longitudinal direction X of the cooling module 22.
- This particular angle may in particular be due to the fact that the non-retracted part of the outer wall 440 retains a curved shape guiding the airflow F.
- Figure 5 finally shows an example in which the outer wall 440 is in its second extreme position.
- the second orientation of the outlet 45 of the air flow F is opposite to the first orientation of said outlet 45 with respect to the longitudinal direction X of the cooling module 22.
- outlet 45 is facing down (as shown in Figure 3), so in its second orientation, outlet 45 will be facing up (as shown in Figure 5).
- the reverse is also possible, i.e. if by example, in its first orientation, the output 45 is oriented upwards, then, in its second orientation, the output 45 will be oriented downwards.
- the cooling module 22 may also include a second collector box 42 arranged upstream of the shroud 40 and of the set of heat exchangers 23, opposite the first collector box 41.
- This second collector box 42 comprises an inlet 42a for the flow of air F coming from outside the vehicle 10.
- the inlet 42a can in particular be arranged facing the cooling bay 18.
- This inlet 42a can also comprise the grid 20 of protection.
- 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 inlet 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 blocking device is configured in particular to allow the air flow F coming from outside G of the vehicle 10 to pass through said inlet 42a in its open position and to block said air flow inlet 42a in its closed 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.
- the flaps can be mounted parallel to the Y direction.
- other configurations such as, for example, flaps mounted parallel to the Z direction.
- other types of shutters such as butterfly shutters are quite possible.
