Abstract
An engine cooling module which includes a shroud , a heat exchanger , a fan , a motor for driving fan , and a plurality of air dams . Shroud , circumscribing the fan, has a main opening to allow air to pass through the fan to or from a heat exchanger . Fan is associated with the shroud to be adjacent to the fan opening to permit air moved by the fan to pass through the heat exchanger. Air dams allow air to flow more easily in one direction than the opposite direction. In the fan flow direction, air dams provide relatively little resistance to the flow. In the direction opposite to fan flow direction, air dams provide more resistance than as compared to the resistance when air flows in the fan flow direction. Under ram air conditions (e.g., when the vehicle is moving), the use of air dams can reduce the load on the fan's motor by cooling properties of ram air, while reducing recirculation, thereby increasing efficiency.
