Enhanced Convective Cooling

      A method of providing cool, unheated air to all critical
modules or components on an air-cooled card is disclosed.
Personalized air flow passages in a molded book cover/enclosure
direct "fresh" cool air to selected regions of the card.

      This disclosure presents a method of providing each air-cooled
card with its own personal, optimized flow arrangement which is
created by connecting an appropriately molded cover to the card.
Each card will get its own cover.  A molded flow cover is created so
that the inlet area occupies the region between two cards, or between
a card and the system wall.  The shape of the cover is card-specific.
Passages or channels molded into the cover direct extra cooling air
to the devices that require it, and it provides a reduced air flow in
those regions that do not require much cooling.  It is possible to
channel/duct air around objects so that devices that are located
behind others get cool, unheated air rather than the air that is
preheated by flowing past the upstream objects.

      A simplified, three-passage, card cover is presented in the
Figure.  An electronics card (1) is populated with high power modules
(2) and an array of lower power modules (3).  Two views are shown in
the Figure, a top or plan view and a side or elevation view.  The
Figure is further broken into three parts (a, b, and c) to highlight
the three personalized air flow passages for the simplified cover
(4).  The c...
