Slotted Riser Card Provides Unrestricted Airflow
Disclosed is
a method of allowing unrestricted airflow inside
desktop computers that have pluggable riser/daughter cards and use a
fan to exhaust hot air from the box.
Any riser
card or daughter card plugged vertically into a
mother board will restrict the cooling airflow across the board and
create hot spots. These high temperature
areas can damage
temperature-sensitive components.
Cooling air
can be moved over hot spots by providing baffles
and deflector mechanisms that add cost and create other hot spots.
Providing
slots or holes in the riser card allows air to flow
through the card (Fig. 2) instead of around the card (Fig. 1). Hot
spots no longer exist and less baffling is needed.
