摘要： The invention is directed to dual purposes of increasing air volume and reducing noises of an inline axial flow fan. In the inline axial flow fan including a first axial flow fan unit 100-1, a first honeycomb 200-2, a second axial flow fan unit 100-2 and a second honeycomb 200-2 which are arranged in the order starting from an upstream side in an air flow direction, the first honeycomb includes a stator vane configured to be warped in a “U” shape against a rotation direction of the first axial flow fan unit, while the second honeycomb includes a stator vane configured to direct a trailing edge thereof in parallel to the air flow direction.

摘要： A fan module and server equipment are provided that can achieve a balance between increased airflow and noise reduction when an axial flow fan is mounted in the server equipment.The fan module for taking in and discharging air includes a stator located on an upstream side with respect to airflow and an axial flow fan located on the downstream side. When the fan module is viewed from the rotational-axial direction of the axial flow fan, if a leading edge of a rotor vane constituting part of the axial flow fan passes a trailing edge of a stator vane constituting part of the rotor, a skew is formed in which the leading edge of the rotor vane constantly intersects the leading edge of the rotor vane at a single point.
