Abstract:
Research and development of high thermal conductivity metal-matrix compositeheat pipe for ???? will continue. The goal is to produce a metal-matrix composite
exhibiting thermal conductivity significantly higher than that of copper, and to
demonstrate performance of this "heat-pipe" material in controlling the temperature
of a demonstration electronic heat source. Variations of "DWG" composite material
(continuous graphite fiber in a metal matrix) tailored to optimize thermal conductivity
will be featured. The objectives are to optimize thermal conductivity; demonstrate
fabrication of generic shapes; develop joining methodology; assess performance of
the material used in real hardware; compile a beginning data base; and promote commercial
sector commitment to sponsor further ManTech programming. It is confidently expected
that DWG exhibiting more than 150% the thermal conductivity of copper can be demonstrated
and that several of the DWG composites will exhibit this high conductivity over the
temperature range -150C +150C. The potential applications for this unique and innovative
material concept are in controlling and dissipating heat from high-power-density
electronics as found in space, robotics, avionics, medical equipment, automative
components, computers, and advanced military systems. All these applications need
the reliability of solid-
state, superconducting "DWG" heat pipe.
