Thermal Management Technologies (TMT)
Abstract
The goal of the Thermal Management Technologies (TMT) program was to explore and optimize new nanostructured materials and other recent advances for use in thermal management systems. The overall goal of the program was to insert breakthrough materials and structures at all layers of DoD systems, and enable higher power densities, increased performance, and improved efficiency. Modern, high-performance heat spreaders, which use two-phase cooling, were developed to replace the copper alloy spreaders in conventional systems. Enhancing air-cooled exchangers by reducing the thermal resistance through the heat sink to the ambient, increasing convection through the system, improving heat sink fin thermal conductivity, optimizing and/or redesigning the complementary heat sink blower, and increasing the overall system (heat sink and blower) coefficient of performance was another thrust of this program. Another element of this effort focused on novel materials and structures that can provide significant reductions in the thermal resistance of the thermal interface layer between the backside of an electronic device and the next layer of the package, which might be a spreader or a heat sink. Technology will be inserted through DoD industrial firms into future DoD systems.
