Abstract

Un disipador (10) de calor incluye una capa (14) térmicamente conductora que comprende por lo menos uno de fulereno y nanotubos dispuestos en un receptor polimérico. La capa térmicamente conductora puede disponerse en un cuerpo de disipador de calor, que puede ser térmicamente aislante y/o plástico y puede incluir estructuras de radiación de calor mejoradoras de área superficial, tal como aletas (16), con la capa térmicamente conductora siendo dispuesta sobre al menos las estructuras de radiación de calor mejoradoras de área superficial. Una modalidad de lámpara de diodos emisores de luz (LED) incluye el disipador de calor y un módulo (30) de LED que incluye uno o más dispositivos (32) de LED asegurados con y en comunicación térmica con el disipador de calor. Una modalidad del método incluye formar el cuerpo de disipador de calor y disponer la capa térmicamente conductora sobre el cuerpo de disipador de calor. La disposición puede comprender recubrimiento por aspersión. Un campo de energía externo puede aplicarse durante el recubrimiento por aspersión para impartir una orientación no aleatoria a los nanotubos en el receptor polimérico.
