Thermo Electric Cooler Feature Card

      This article describes the use of a feature card location in a
personal computer (PC) for the purpose of microprocessor
environmental control.  This environmental control is accomplished
using a voltage regulator, the supply and a thermal electric cooler
(TEC).

      Wherever the microprocessor is placed in a PC, there is a
possibility that its heat sink interferes with either a hard file or
feature card, etc.  There is generally a lack of "headroom" for heat
exchanging.  In the design disclosed herein, the feature card draws
electrical power for the TEC from the PC bus and dissipates the
thermal energy generated by the microprocessor.  The heat sink is
very large, approximating an ideal cold plate.

      In the drawings, Fig. 1 is a front view, Fig. 2 is a top
view and Fig. 3 is a side view of the TEC and feature card.  Fig.
4 is a detail view of the flange area.  The key here is the fact
that the feature card is no longer in the way, but instead is used to
bring electrical power into the TEC and to shed the thermal power
because it is also a heat sink.
