Abstract: An axial cooling fan for a vehicle includes an electrically powered motor operable to rotate fan blades to move air to cool a component or accessory of the vehicle. A stator is at the motor and has a plurality of struts that fixedly support the motor at the vehicle. The struts of the stator include leading edge surfaces that generally face air that is flowing towards the struts and past the struts and stator, such as when the motor is powered to rotate the fan blades. The leading edge surfaces of the struts comprise an aerodynamic design or pattern or structure established thereat, such as a toothed pattern or structure at the leading edge surfaces of the struts.

Abstract: A fan arrangement for a heat exchanger of a motor vehicle, a system for a motor vehicle, and a motor vehicle. A fan is arranged downstream of the heat exchanger in an air supply direction. The fan is arranged in a fan cowling which covers an air passage area of the heat exchanger and which is arranged spaced from the heat exchanger in an axial direction and coupled to the heat exchanger via a sealing part. A plurality of air passages having openings are arranged opposite each other in the sealing part. The dimensions of the air passage openings in a direction perpendicular to the air supply direction, in relation to the peripheral area of the sealing part, is at least a factor of 0.025 of the diameter of the fan, and the dimensions of the air passage openings in the direction of the air supply, is at least 0.0025 of the diameter of the fan.

Abstract: Air guide for a fan cowling of a motor vehicle, the fan cowling being arranged downstream of a heat exchanger in a direction of airflow. The air guide includes an air guide body having a plurality of surfaces and an air passage opening arranged between adjacent surfaces of the air guide body, a guide surface which corresponds to the opening and configured to act on airflow through the air passage opening; and an end region which extends from the guide surface and which is spaced from and extends in a plane which is substantially parallel to a plane of the surface of the air guide body. The guide surface begins at a first edge of the air passage opening and the end region ends at the opposite edge of the opening, and the end region does not overlap with an adjacent surface that continues at the opposite edge of the air passage opening.
