- an actuator can be configured to move all of the air outlet valves 42 jointly.
- the heat exchange module 22 further comprises at least one closure panel 44.
- the closure panel 44 is for example a curtain. It can be made of a rigid or flexible material. This closure panel 44 is intended to separate the internal air channel into at least two air flow paths 331, 332 and to isolate them advantageously in a sealed manner.
- the closure panel 44 is mounted to move between a stowed, folded position and a deployed position.
- the shutter panel 44 In the deployed position, as shown in Figure 4, the shutter panel 44 extends between the first heat exchanger 24 on the one hand and the additional air inlet 35b and the second heat exchanger 26 on the other.
- the closure panel 44 is in the deployed position when the air inlet valve 37 releases the corresponding additional air inlet 35b.
- the closing panel 44 deployed, thus delimits and isolates a first air flow path 331 from the first air inlet 35a to the second air outlet 40b, and a second air flow path air 332 from the additional air inlet 35b to the first air outlet 40a.
- the blanking panel 44 can extend between, on the one hand, a first heat exchange group and, on the other hand, the additional air inlet 35b and a second heat exchange group.
- Each blanking panel 44 makes it possible in this case to isolate two air flow paths from an air inlet to an air outlet.
- one of the end air flow paths places the first air inlet 35a in fluid communication with an air outlet downstream of a second tangential turbomachine 30b.
- the other air flow path at the end puts in fluid communication an additional air inlet 35b and the first air outlet 40a.
- the intermediate air flow path or paths can put an additional air inlet 35b and an air outlet downstream of a second tangential turbomachine 30b in fluid communication.
- the shutter panel 44 is for example intended to be rolled up around a winding axis B.
- the winding axis B of the shutter panel 44 is for example transverse to the axis alignment of the heat exchangers 24, 26.
- the winding axis B is parallel or substantially parallel to the axis of rotation A, respectively A', of the first 30a, respectively second 30b, turbomachine tangential.
- the winding axis B is here parallel to the transverse axis Y.
- the heat exchange module 22 may include one or more elements for fixing the blanking panel(s) 44 to the box 32.
- the heat exchange module 22 may include a drive mechanism for the shutter panel 44, advantageously motorized.
- the control unit or another may comprise one or more processing means for controlling the actuation of the shutter panel 44, and therefore of the corresponding drive mechanism.
- the heat exchange module 22 may further comprise a control unit (not shown). It can be, for example, a calculator.
- This control unit comprises one or more processing means for controlling one or more of the actuators (not shown) of the sets of shutters 31, 31', of the valves 37, 42, and/or of the drive mechanism of the shutter panel 44.
- Figure 3 illustrates a first operating configuration, which may be a standard configuration.
- a single air flow path is defined in the internal air channel 33, from the first air inlet 35a to the first air outlet 40a downstream of the first tangential turbomachine. 30a.
- the first flow of air F1 is set in motion and passes through the first grille part of the motor vehicle equipped with the heat exchange module 22, enters the box 32 through the first air inlet 35a then crosses all of the heat exchangers 24, 26 before leaving the heat exchange module 22 through the first air outlet 40a downstream of the first tangential turbomachine 30a.
- the air flow downstream of the first tangential turbomachine 30a is directed towards the lower body of the motor vehicle equipped with the heat exchange module 22.
- the arrangement of the air inlet valve 37 to block the additional air inlet and the arrangement of the second set of flaps 31' so as to block the opening of the second part of the frame 29, make it possible to prevent the generally hot air which is evacuated downstream of the first tangential turbomachine 30a from being sucked back into the casing 32. In other words, this avoids “polluting" the fresh air entering the casing 32 by hot air having already passed through the heat exchangers 24, 26.
- Figure 4 illustrates a second operating configuration, which may be a fast charge configuration.
- the two air inlet 37 and air outlet 42 valves are open. Moreover, the two sets of shutters 31, 31' are arranged to release the openings of the frame 29.
- the shutter panel or curtain 44 is deployed. It makes it possible to delimit, to isolate, the two air flow paths 331, 332.
- the closing panel 44 is deployed between the first heat exchanger 24 and the second heat exchanger 26.
- the air channel that there would be between the first heat exchanger 24 and the second heat exchanger 26 (as described with reference to the first operating configuration) is thus condemned.
- the blanking panel 44 makes it possible to isolate the additional air inlet 35b from the first air inlet 35a and from the first heat exchanger 24.
- the first air flow path 331 puts the first air inlet 35a in fluid communication with the second air outlet 40b, while the second air flow path 332 puts the inlet in fluid communication. additional air 35b with the first air outlet 40a.
- the blanking panel 44 could be deployed between two heat exchange groups or sets of heat exchangers. Several blanking panels 44 could also be deployed between the heat exchange groups or sets of heat exchangers.
- the two tangential turbomachines 30a and 30b can operate. Thus, each makes it possible to set in motion an air flow intended to pass through the heat exchanger(s) in the associated air flow path 331, 332.
- the second tangential turbomachine 30b can set in motion a second flow of air F2 which is intended to pass through a first part of the grille, enter the casing 32 through the first air inlet 35a and pass through the first heat exchanger 24 before leaving the box 32 through the second air outlet 40b.
- the second air flow F2 crosses the first heat exchanger 24 without circulating through the second heat exchanger 26.
- the first turbomachine 30a for its part, can set in motion a third air flow F3 intended to pass through a second part of the grille, enter the casing 32 through the additional air inlet 35b, pass through the second heat exchanger 26 before to leave the box 32 by the first air outlet 40a.
- the third flow of air F3 passes through the second heat exchanger 26 which is located after the additional air inlet 35b, along the longitudinal axis X, without circulating through the first heat exchanger 24.
- This configuration is particularly interesting because it allows a supply of fresh air upstream of the second heat exchanger 26. This makes it possible to optimize the cooling performance of the second heat exchanger 26.
- second and third airflows F2, F3 are used to distinguish the airflows F2, F3 set in motion, in particular sucked in, by the two tangential turbomachines 30a, 30b according to the second operating configuration, of the first airflow F1 described with reference to the first operating configuration.
- FIG. 5 illustrates a third operating configuration, corresponding to an intermediate mode.
- This third operating configuration can be advantageous in particular when the first heat exchanger 24 requires more cooling. This may be the case for example when it comes to an evapo-condenser.
- This evapo-condenser can be configured to dissipate / evacuate the heat captured at the level of a liquid cooler type exchanger, or water cooler, also called "chiller" in English, itself configured to dissipate the heat generated by at least one electronic and/or electric component (such as batteries of an electric motor vehicle).
- the air inlet valve 37 between the two heat exchangers 24, 26 is closed, and conversely the air outlet valve 42 at the level of the second tangential turbomachine 30b is open.
- the flaps 31 of the first set release the opening of the first part of the frame 29, while the flap or flaps 31' of the second set block the opening of the second part of the frame 29.
- the shutter panel 44 is stored, for example folded or retracted.
- the two tangential turbomachines 30a, 30b can operate. They set in motion an air flow F which enters the box 32 through the first air inlet 35a. All the air flow F sucked in passes through the first heat exchanger 24. A first part of the air flow F′ downstream of the first heat exchanger 24 is evacuated through the second air outlet 40b. A second part of the air flow F” downstream of the first heat exchanger 24 also passes through the second heat exchanger 26 before being evacuated through the first air outlet 40a.
- all the air flow F drawn in would pass through a first set of heat exchangers before the or a second tangential turbomachine 30b.
- the first part of the air flow F′ downstream of the first set of heat exchangers would be evacuated by the or a second air outlet 40b.
- the second part of the air flow F′′ downstream of the first set of heat exchangers would pass through a second set of heat exchangers before being evacuated through the first air outlet 40a.
- the air flows downstream of the first tangential turbomachine 30a and of the second tangential turbomachine 30b are directed towards the bottom of the body of the motor vehicle equipped with the heat exchange module 22.
- the air inlet valve 37 closing the additional air inlet and the second set of flaps 31' closing the opening of the second part of the frame 29, make it possible to prevent the generally hot air which is evacuated downstream of the tangential turbomachines 30a, 30b is not sucked back into the casing 32, thus avoiding “polluting” the fresh air entering the casing 32 with hot air.
- the heat exchange module 22 may further comprise one or more flaps 46 arranged at the rear end of the box 32, on the side opposite the first air inlet 35a. These are, for example, flaps 46 pivotally mounted between an open position allowing circulation of at least one air flow and a closed position.
- the open position can be particularly advantageous at high speed of the motor vehicle, and when the tangential turbomachines 30a, 30b are stationary.
- the closed position can be advantageous at low speed of the motor vehicle, and at least one of the tangential turbomachines 30a, 30b is operating.
- the axis of pivoting of the flaps 46 can be parallel or substantially parallel to the axis of rotation A, respectively A′, of the first 30a, respectively second 30b, tangential turbomachine.
- Other configurations are possible.
- the flaps 46 are therefore arranged in an inclined plane forming in this example a non-zero angle a with an axis orthogonal to the axis of alignment of the heat exchangers 24, 26 and to the axis of rotation A of the first tangential turbomachine 30a, that is to say with the vertical axis Z when the heat exchange module 22 is fitted to a motor vehicle.
- the angle a is preferably between 5° and 20°. This angle a ensures a homogeneous distribution of the air on the heat exchangers 24, 26.
- the second tangential turbomachine(s) 30b make it possible to increase the air flow and meet a greater need for fresh air from the heat exchange module.
