A system for controlling an air heat exchanger of a vehicle includes an information collector which collects environmental information including a current speed of a vehicle, a desired air mass flow rate, and an ambient temperature. A storage stores the environmental information therein. A controller calculates a driving load and a cooling load in accordance with the environmental information and calculating a control amount of an air heat exchanger, at which a cost function that is a sum of the driving load and the cooling load is minimum.

The invention relates to a cooling module (22) for a motor vehicle, preferably having an electric motor, comprising: —at least one heat exchanger (24, 26, 28), —at least one tangential turbomachine (30) capable of creating a flow of air in contact with said at least one heat exchanger (24, 26, 28), and —a fairing (40) for housing said at least one heat exchanger (24, 26, 28), wherein the fairing (40) comprises at least one indentation (34-1, 34-2, 36-1, 36-2, 38-1, 38-2) for retaining at least one heat exchanger.

A ventilation device for a motor vehicle includes a frame defining an opening for an air flow, and at least one flap mounted so as to rotate relative to the frame about a pivot axis between an open position, suitable for allowing the air flow to pass, and a closed position, suitable for reducing the intensity of the air flow or changing its direction. The flap extends along the pivot axis and has a first end and a second end that are opposite one another along this axis and mounted so as to rotate on the frame around the pivot axis. The ventilation device further includes an intermediate support located between the first end and the second end along the pivot axis. The flap is mounted so as to rotate on the intermediate support relative to the frame about the pivot axis, the intermediate support being attached on the frame.

The invention relates to a cooling system for a vehicle, the cooling system comprising a cooling fan comprising a ram air turbine disposed in an aperture of a fan shroud, the fan shroud comprising: an opening, a shutter mechanism movable between a closed position in which it closes the opening, and an open position in which it opens the opening so that a ram air flow can pass through the opening, wherein the fan shroud further comprises: a velocity sensor configured to measure ram air flow velocity, a temperature sensor configured to measure ram air flow temperature, and an actuator configured to move the shutter mechanism between the closed position and the open position based on measured ram air flow velocity and measured ram air flow temperature.

An active dual roll shutter apparatus for a vehicle has two lead screws rotated by power from a single motor. First and second roll screens are simultaneously operated upward and downward in opposite directions along the two lead screws to open a flow path when the lead screws rotate, thereby improving sealability of the flow path and aerodynamic performance of the vehicle.

A cooling system includes a first cooler, a second cooler, a fan positioned to drive air through the first cooler and the second cooler, and a baffle system. The baffle system includes a baffle and an actuator. The baffle is positioned to facilitate selectively restricting airflow through at least a portion of the first cooler. The actuator is positioned to facilitate reconfiguring the baffle between (i) a first orientation where the baffle does not restrict the airflow through the portion of the first cooler and (ii) a second orientation where the baffle restricts the airflow through the portion of the first cooler, thereby diverting additional airflow through the second cooler.
