A fan assembly comprising a fan, a stationary airflow directing device and a support inner ring. The fan has a hub portion and a plurality of fan blades. Each of the fan blades has a root region and a tip region. The root regions of each fan blade are secured to the hub portion wherein the fan blades extend substantially radially of a fan rotational axis. The airflow directing device has a plurality of stator blades extending radially about the support inner ring. The stator blades receive air flow from the fan and divert the airflow. The surface area of the stator blades is substantially less than the surface area of the fan blades. Each stator blade has a planar surface and a curved surface opposing the planar surface. The planar surface is disposed such that rotational components of air flow from the fan are incident on the planar surface.
A fan assembly comprising an axial flow fan, an airflow directing device, and a support inner ring, said fan having a hub portion and a plurality of fan blades, each fan blade having a root region and a tip region, the root regions of each fan blade being secured to the hub portion, the airflow directing device having a plurality of stator blades and a stator support outer ring, said plurality of stator blades extending radially about said support inner ring, each stator blade having a tip region and a substantially constant chord length over about the first 50% of the distance between the support inner ring and the stator support outer ring, and thereafter the chord length increases, said stator blades receive air flow from said fan and divert said airflow, wherein the surface area of the stator blades is substantially less than the surface area of the fan blades.
A fan assembly comprising an axial flow fan, an airflow directing device and a support inner ring, said fan having a hub portion and a plurality of fan blades, each fan blade having a root region and a tip region, the root regions of each fan blade being secured to the hub portion, the airflow directing device having a plurality of stator blades extending radially about said support inner ring, each stator blade having a tip region, said stator blades receive air flow from said fan and divert said airflow, wherein the surface area of the stator blades is substantially less than the surface area of the fan blades, wherein each stator blade has a first and a second surface, said first surface is planar and said second surface is curved wherein said first surface is disposed such that rotational components of air flow from said fan are incident on said first surface.
An air flow directing device for use with an axial flow fan, the device comprising a support inner ring for supporting the fan and a plurality of stator blades extending radially about said support inner ring, said stator blades receive air flow from said fan and direct said air flow, wherein each stator blade has a tip, a first surface, and a second surface, said second surface opposing said first surface, said first surface being substantially planar and disposed such that rotational components of air flow from said fan are incident on said first surface, and said second surface being curved.
