Claim 11:
12. A server system, comprising:
a fan container having an exterior surface;
a plurality of cooling fans housed within the fan container, each fan of the plurality of cooling fans having a plurality of rotatable blades, the plurality of rotatable blades forming a center of rotation and capable of causing an air flow, 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 moving the 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 being downstream from the plurality of cooling fans, the fan guard including:
a housing having a hollow interior defined by a cylindrical inner surface, 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 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; and
a plurality of wings positioned within the hollow interior of the housing, each wing of the plurality of wings being radially curved between the first housing end and the second housing end, each wing being radially curved into 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.
