Abstract
A fan module for a vehicle engine cooling system includes a pair of co-axial, counter-rotating, axial flow fans. Each fan is supported on and driven by a dedicated downstream motor, and each motor is supported by a dedicated shroud. The shroud that supports the first motor includes a barrel, a motor carrier that is surrounded by the barrel, and vanes that extend between the barrel and the motor carrier. For each vane, a line that extends between the vane nose and the vane tail is angled relative to the fan rotational axis, and the angle is selected to minimize air flow losses through the shroud.
