Abstract

Disclosed embodiments relate to a housing for a fan that is constructed by cutting, bending, and/or folding a single sheet of metal. A disclosed housing is configured to house a fan having a motor that is configured to rotate around an axial direction. The housing includes a first plate that is oriented in a plane that is perpendicular to the axial direction and substantially flat wall regions extending away from the first plate so as to be non-coplanar with the first plate. The housing further includes a second plate having an air intake nozzle, the second plate oriented perpendicularly to the axial direction and thereby oriented parallel to the first plate and located a first distance along the axial direction from the first plate, with the first distance being determined by a length of the wall regions. The wall regions are configured to include air flow openings.
