A mid-mounted radiator in a motor vehicle has at least one outgoing air guide attached laterally on the left and right of the radiator. In vehicles with a relatively low cooling requirement, the lateral outgoing air guides are removed and the openings are closed by a cover.

An air-governing device (10) for governing an air flow into a vehicle (100) has a main body (20) with an installation section (22) for fastening to a body of the vehicle (100) and an air opening (24). At least one slat (30) is mounted on the main body (20) for movement between a closed position (SP) closing the air opening (24) and an open position (OP) opening the air opening (24). A drive device (40) is fastened to the main body (20) and generates a moving force for the slat (30). A lever mechanism (50) forms an operative connection between the drive device (40) and the at least one slat (30). The lever mechanism (50) has at least one drive lever (52) operatively connected to the drive device (40) in a torque-transmitting manner and fastened in an end position (EP) of a keyhole opening (26) in the main body (20).

A cooling module for an electric or hybrid motor vehicle, through which an air flow is intended to pass, having a set of heat exchangers including a first heat exchanger and a second heat exchanger; a fan casing disposed downstream, the fan casing having an outlet for the air flow; a tangential turbomachine configured so as to generate the air flow; the cooling module further including: an air discharge vent disposed downstream of the outlet for the air flow of the fan casing; and a bypass connecting the outlet for the air flow to an opening upstream of the set of heat exchangers; the air discharge vent having a closure device configured so as to redirect the air flow from the outlet towards the outside of the vehicle when in the discharge position and to redirect the air flow towards the bypass when in the recirculation position.

A vehicle includes a traction battery and a cooling system. The cooling system has a chiller, a radiator, and conduit and valving arranged to form a thermal circuit configured to selectively transport heat via coolant from the traction battery to the radiator. The vehicle also includes a grille shutter assembly having an opening and shutters movable to alter an effective cross-sectional area of the opening. A controller is programed to operate the shutters to change the effective cross-sectional area of the opening to increase or decrease air flow over the radiator based on a temperature of the coolant and an ambient air temperature.

An assembly for improving aerodynamics of a motor vehicle including a movable member forming an active aerodynamic dam positioned at a front end of the motor vehicle and attached to one end of at least one lever, wherein the at least one lever is connected to a motor that powers movement of the movable member, wherein the motor is operatively connected to at least one sensor configured to provide an input to the motor, the motor with a gear selector disposed within the motor that is configured to move a motor gear from a first gear position to a second gear position, resulting in the movable member being disposed in one of a retracted position, a transition position, and a lowered position, based on the received input.

A shutter system includes a housing, and a plurality of shutters coupled to the housing. Each of the shutters is rotatable about a respective rotation axis, between a first position and a second position. At least one actuator is attached to the housing, and is coupled to at least one of the shutters for moving that shutter between its respective first position and second position. Each of the shutters define a first angle relative to a reference axis when disposed in their respective first position, and a second angle relative to the reference axis when disposed in their respective second position. The first angle of each of the shutters is substantially equal to the first angle of all other of the shutters. The second angle of at least one of the shutters is different than the second angle of at least another of the shutters.

A grille for a vehicle is disclosed. The grille is configured to be arranged in front of at least one heat exchanger of the vehicle and includes a plurality of grille bars arranged at a distance from one other. A respective portion of each of the plurality of grille bars is airfoil-shaped.

A heat exchanger system for an agricultural vehicle. The heat exchanger system has at least two separate heat exchanger assemblies, where an adjustable baffle is used to vary the airflow between the heat exchanger assemblies, accordingly varying the cooling effect of the assemblies, based on system requirements. The adjustable baffle may be arranged to restrict or block at least a portion of a heat exchanger to reduce airflow through the exchanger, to provide a flow bypass of an exchanger, and/or to proportionally adjust the airflow through a pair of heat exchangers provided as part of a single heat exchanger assembly.

A vehicle underbody cover structure includes: a first splash shield placed below a cooling object and having a service hole; and a service lid detachably attached to the first splash shield such that the service lid covers the service hole. The service lid includes a lid-side vertical wall standing in the up-down direction, the lid-side vertical wall being placed ahead of the cooling object in the vehicle front-rear direction. The lid-side vertical wall has an air-cooling hole provided in a penetrating manner in the vehicle front-rear direction such that travel wind passes through the air-cooling hole, the air-cooling hole being provided to at least partially overlap with the cooling object in the vehicle width direction.
