Multi-feature Card Guide Structure

      Described is a multi-feature card guide structure to be
used in personal computer system housings which require densely
packed system components.

      The primary objective of the multi-feature card structure is to
provide a means of housing high-powered circuit components in a
densely packed environment while enabling high air velocity for
cooling purposes.  The high air velocity is routed from the sides of
the card structure through a ducted area created by a shield (not
shown) in the top cover and from the front bezel openings in the
cover to the card guide section.

      Fig. 1 is an exploded perspective view of a personal computer
housing.  The concept described herein centers about card guide
structure 10.  Fig. 2 is a detail view  of structure 10.  Structure
10 is made of a plastic material to provide electrical isolation of
the leads and components from the metal system unit frame.  Structure
10 contains four pairs of ribs 11 that align, guide and support four
separate circuit cards (not shown) as required by the system.  A
fifth pair of ribs 12 provides the card guide function for the system
processor card.  Plenum area 13 is designed to enable the mounting of
an 80 mm standard axial flow fan at four screw positions.  Fans with
different flow rates may be installed at this location to provide for
optimal cooling.  Air baffle 14 is located adjacent to plenum area 13
and is used to ensure that accelera...
