A radiator shutter for a motor vehicle includes a carrier, which has a cross-sectional surface, through which air can flow, at least one lamella, which is arranged on the carrier, and which has a longitudinally extended flexible and elastic bending rod and at least one planar segment, wherein the planar segment is connected to the bending rod along a side edge.

The invention relates to an air inlet arrangement for a vehicle, having a frame-like carrier element in which at least one first ventilation flap is arranged, the at least one first ventilation flap being rotatable about an axis of rotation between a first, closed position and a second, opened position, the at least one first ventilation flap having a first terminal end portion and a second terminal end portion as viewed in the direction of the axis of rotation, the first end portion being at least indirectly rotatably mounted on the carrier element and being fixed against an axial stop as viewed in the direction of the axis of rotation, and the second terminal end portion being at least indirectly connected by means of a connecting element to an actuating drive for rotating the at least one first ventilation flap about the axis of rotation.

A vehicle has an engine (26), a power storage device (10), two motor/generators (M/G1, M/G2), a front grille with a shutter, an engine room, a first temperature sensor, a second temperature sensor, and a controller. The shutter changes the amount of air introduced from the front grille into the engine room. The first temperature sensor detects a temperature (Tw) of a coolant of the engine, and outputs the detected coolant temperature to the controller. The second temperature sensor detects an outside air temperature (Te), and outpots the detected outside air temperature to the controller. The controller starts the engine (26) when the coolant temperature is equal to or lower than a threshold value. When the coolant temperature is higher than the threshold value, and the vehicle starts traveling in a first mode with power from the power storage device (10), the controller drives the shutter such that the amount of the air is reduced when the coolant temperature (Tw) is higher than the outside air temperature (Te).

An active air flap system mounted in a predetermined portion of a vehicle, includes: a housing, a flap mounted on the housing to be relatively movable, an actuator coupled to the at least one flap and configured to drive the at least one flap, and a power transfer mechanism engaging the actuator and the flip and configured to transfer power from the actuator to the at least one flap so that the at least one flap performs a dual operation of a sliding movement operation and a rotation operation of rotating around a predetermined rotation axis, preventing the occurrence of design heterogeneity and the air resistance caused by forming the space between the at least one flap and the radiator grill, and improving shielding properties.

A radiator unit includes a cooling air duct, a first heat exchanger that is arranged in the cooling air duct and incompletely fills out the cross section of the cooling air duct and a second heat exchanger that fills out at least the part of the cross section not filled out by the first heat exchanger. An air flap arrangement meters a cooling air flow through the heat exchangers. A first part of the air flap arrangement predominantly fluidically overlaps the first heat exchanger. A second part of the air flap arrangement predominantly fluidically overlaps the part of the cross section not filled out by the first heat exchanger. The air flaps of the first and second part are coupled for swiveling in opposite directions around axes that are parallel to a boundary between the two parts.

A flap system for supplying cooling air of a motor vehicle, and which includes a drive component which receives and supports at least one flap element to be pivoted about a longitudinal axis. The flap element is to be supported at ends thereof by a shaft which is received in a cylindrical bearing receiving member of a rail.

A grille shutter is a device configured to adjust a temperature of coolant water of an engine by adjusting an amount of outside air introduced into a radiator of the engine. An ECU performs a failure diagnosis for the engine based on a temperature of coolant water of the engine. When the grille shutter is immovable in an opened state of the grille shutter regardless of an operating command to the grille shutter, the ECU renders the failure diagnosis process for the thermostat valve not to be executed. As a result, an incorrect operation of various controls executed based on a temperature of coolant water of the engine can be suppressed.

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.
