Patent ID: 7173822

Claim:
A support assembly for supporting electronic circuitry, the electronic assembly comprising: a frame configured to hold the electronic circuitry; a fan subsystem coupled to the frame; and a panel member attached to the frame, the panel member is disposed at an input location of the frame, and the panel member including: a mounting portion configured to mount to the frame; a face portion coupled to the mounting portion, the face portion defining a plane and multiple openings within the plane, the face portion has a first depth which is measured in a direction that is perpendicular to the plane; and multiple brimmed portions coupled to the face portion, each brimmed portion (i) extending around an opening defined by the face portion and (ii) projecting from that opening in a direction which is away from the plane, the face portion and multiple brimmed portions forming ventilation pathways for an air stream provided by the fan subsystem in order to cool the electronic circuitry wherein the face portion in combination with any of the multiple brimmed portions forms a projecting edge having a second depth which is measured in the direction that is perpendicular to the plane, and wherein the second depth is substantially greater than the first depth to provide enhanced electromagnetic interference shielding characteristics to the panel member and the face portion in combination with the multiple brimmed portions defines a set of tapered holes as the ventilation pathways, and wherein the face portion in combination with the multiple brimmed portions defines a set of conical shaped apertures as the set of tapered holes with larger diameters facing away from the electronic circuitry and smaller diameters facing the electronic circuitry.
