Abstract
An axial-flow fan for a vehicle radiator includes a fan wheel that delivers the main air flow and is driven by a hub motor coupled to the fan wheel. The vehicle radiator is on the intake side of the fan wheel, the hub motor during operation is cooled by a secondary air flow, and the cooling air flow of the hub motor flowing out from an air outlet opening is on the intake side in the hub area of the fan wheel. An air baffle device including a propeller is assigned to the hub motor and the cooling air flow passing through the air baffle device is led out of the air outlet opening, avoiding disturbances of the main air flow delivered by the fan wheel.
