摘要： An axial fan, having an inner electric motor and a fan wheel connected to the electric motor so as to rotate with it and has a plurality of wheel blades defining a blade length and extend outwardly from the electric motor. A fan housing surrounds the fan wheel. The fan housing is connected to the motor via holding struts which extend to the outside from the motor to the fan housing. A motor housing is provided on the motor behind the fan wheel and accommodates a motor electronics system. A flow duct having an inflow opening and an outflow opening is fastened to the motor behind the fan wheel such that the inflow opening is arranged offset to the outside with respect to the outflow opening. The outflow opening is oriented in such a way that an air flow which exits the outlet opening is guided onto the motor housing.
