Abstract

A means is proposed to obtain work from the heat dissipation from electronic equipment, which includes individual components as well as entire systems. As power is inputted into the integrated circuits, heat is dissipated. This heat is generally transmitted into the environment by means of heat sinks, air fans, heatpipes, etc. This resultant heat only increases the entropy of the environment and does not provide any positive attributes back to the system.

Entropy Management for Computer Systems

      A means is proposed to obtain work from the heat dissipation
from electronic equipment, which includes individual components as
well as entire systems.  As power is inputted into the integrated
circuits, heat is dissipated.  This heat is generally transmitted
into the environment by means of heat sinks, air fans, heatpipes,
etc.  This resultant heat only increases the entropy of the
environment
and does not provide any positive attributes back to the system.

      A system can be developed to use this discarded heat to
generate useful power back into the system.  The means of this
electronic power could be accomplished by any of several means.
These include, but are not limited to:
  o  thermo-chemical closed loop,
  o  open loop power or,
  o  piezo electric.

      The generation of power from the heat dissipation can be used
to provide several advantages.  In the case of portable systems, the
power generation can be used to extend the battery life of the
system.  For larger computer systems which generate hundreds of
watts/sq-cm, a very efficient power system could be designed to
harness a Carnot efficiency in the order of 10-20%.  A size and cost
reduction of the power supply could be realized by this system by use
of this concept.  Additionally, the expense and noise of fans to cool
computer systems could be eliminated.
