Abstract
An engine cooling module 10 includes a shroud 12 having at least one fan opening 15 and at least one additional opening 18 in the wall generally adjacent to the fan opening to permit air to pass though the shroud 12. A fan 14 is coupled to the shroud to permit air moved by the fan to pass through the shroud 12. An electric motor drives the fan. Closure structure 20 is movable to prevent and permit air flow through the additional opening 18. An actuator 28 moves the closure structure 20 from a closed position, covering the additional opening 18, to an opened position, uncovering the additional opening 18. A sensor 34 detects ram air at the shroud 12. A controller 32 receives a signal from the sensor 34 indicating the initial presence of ram air and, in response thereto, sends a signal to the actuator 28 to move the closure structure 20 to the opened position.
