Abstract

It is proposed to use the extraneous heat released by a heat exchanger of a liquid cooled computer, such as a workstation, in a manner that would reduce the system power requirements. This has the advantage of decreasing the amount of power required for the system as well as reducing the amount of waste heat dissipated into the office environment.

Enhance Thermal Performance for Liquid Cooled Systems

      It is proposed to use the extraneous heat released by a heat
exchanger of a liquid cooled computer, such as a workstation, in a
manner that would reduce the system power requirements.  This has the
advantage of decreasing the amount of power required for the system
as well as reducing the amount of waste heat dissipated into the
office environment.

      In liquid cooled systems, cooling is accomplished by
circulating fluids, typically water, around the system to the hot
components of the system.  The fluid collects the heat, cooling the
devices, and dissipates its heat in a heat exchanger which in turn
transfers heat to the surrounding air.  Efficiency of the exchanger
is often enhanced by moving air around the exchanger.

      The disclosed concept uses this significant amount of heat to
generate power which can be applied to an internal power grid
reducing the amount of power that is required externally.  This power
can be used to drive some of the cooling elements of the system,
including fans.  A typical application is shown in the Figure.
