摘要： An axial flow fan is provided that is arranged in a rotatable manner around an axis in a stationary shroud ring, with fan blades. The shroud ring has an essentially cylindrical annular surface with an axial extension from a leading edge to a trailing edge and the fan blades have an axial depth from an inflow edge to an outflow edge. The outflow edges of the fan blades in an axial direction project beyond the trailing edge of the annular surface and form a blade overhang and flow guidance elements are arranged radially outside the fan blades as well as in the axial region of the blade overhang.
