Claim 0:
1. A server system comprising:
a fan container having an exterior surface;
a plurality of cooling fans positioned within the fan container, the plurality of cooling fans including a first fan and a second fan, the first fan being positioned adjacent to the second fan, the first fan creating an air flow towards the second fan, the second fan continuing the air flow towards the exterior surface of the fan container; and
a fan guard coupled directly to and extending from the exterior surface of the fan container, the fan guard being outside the fan container and adjacent to the second fan, the fan guard receiving the air flow in an area outside the fan container, the fan guard including
a housing having a hollow interior defined by a cylindrical inner surface, the cylindrical inner surface defining a full cylindrical shape for the hollow interior, the housing extending longitudinally between a first housing end and a second housing end, the first housing end being adjacent to the exterior surface of the fan container, the second housing end being outside and away from the exterior surface of the fan container, the housing being configured to receive the air flow from the plurality of cooling fans, the air flow entering at the first housing end and exiting at the second housing end, the housing further having an outer surface that includes a cylindrical portion and a non-cylindrical portion, the non-cylindrical portion including two opposing straight edges extending from respective intersections with the cylindrical portion, the two opposing straight edges being connected by an intermediate straight edge that is generally perpendicular to each of the two opposing straight edges; and
a plurality of wings positioned within the hollow interior of the housing, each wing of the plurality of wings extending radially from a center of symmetry of the cylindrical inner surface to the cylindrical inner surface, each wing of the plurality of wings having a radial curvature between the first housing end and the second housing end, the radial curvature forming a concave shape that extends longitudinally between the first housing end, where the air flow enters, and the second housing end, where the air flow exits, the concave shape of each wing being (a) closer to the first housing end at the center of symmetry and (b) closer to the second housing end at a point of contact with the cylindrical inner surface.
