Zusammenfassung:An axial ventilator for a cooling system in a rail vehicle is provided to reduce a noise by making a sweep angle between a connection line and a tangential line meet a non-linear function. An axial ventilator for a cooling system in a rail vehicle comprises a blade wheel(1) having one hub and plural blades(3) such as sickle blades, and a connection line wherein the center of sections is three-dimensionally bended. The sweep angle between the connection line and a tangential line meets a non-linear function.
