Abstract:

This Phase I SBIR project has investigated a lightweight packaging design for phase change materials PCMs used in thermal management. To control expansion stress, conventional PCM heat sinks have strong encapsulation that weighs more than the PCM they contain. The objective of this work is to develop PCM heat sinks configured as thin sandwich plates, in which the mass of the encapsulation is a small fraction of the PCM mass. The design is based on a lightweight carbon fiber core that has suitable mechanical, thermal, and capillary properties. PCM composite plates were fabricated with dimensions 15x15x0.6 cm3 and with a dodecan, sealed, and successfully tested in thermal-vacuum environment. No performance degration was observed after 100 deep thermal cycles in air. A lightweight design incorporating heat pipes was demonstrated. It appears feasible to fabricate such plates with thickness 1-10 mm and with organic PCM mass fractions exceeding 75. Thick heat sinks may be formed by laminating thin plates.
