An electronic device includes a housing with a plurality of sides and electronics components in the housing. A porous and thermally conductive material is associated with the housing. The material has a thermal conductively (k), and a porosity between 10% and 70% that results in a specific heat (&rgr;) and density (Cp) for the material, such that k*&rgr;*Cp is between 0 (J*W)/(m4*K2) and 1,000,000 (J*W)/(m4*K2). The material may be: a glass-based material having a thermal conductivity between 0.5-2 W/m-K, a density between 1000-2500 kg/m3, and a specific heat between 500-1000 J/kg-K; a metal-based material having a thermal conductivity between 300-400 W/m-K, a density between 4000-8000 kg/m3, and a specific heat between 200-300 J/kg-K; and a plastic-based material having a thermal conductivity may be between 0.1-0.4 W/m-K, a density between 400-1000 kg/m3, and a specific heat between 1900-2000 J/kg-K. |
