摘要:
A cooling system includes a cooling fan with an outlet and an inlet and a shroud surrounding at least a portion of the cooling fan. The cooling fan includes a plurality of fan blades, and each fan blade includes an inlet portion and an outlet portion that define an outer periphery of the fan blade. The outlet portion has a profile defined by a radial distance, perpendicular from a central axis of the fan, increasing in a direction towards the outlet. The average angle, relative to a central axis of the fan, of either a profile of the outlet portion or a profile of a portion of the shroud surrounding the outlet portion is between about ±15° of an average angle to the central axis at which a flow of fluid exits the outer periphery of the fan blades or between about 20° and about 70°.
