Abstract

"MATERIAL DE ACUMULADOR TéRMICO LATENTE". A presente invenção refere-se a um material acumulador térmico latente, o qual é formado como material composto de um material trocador de fases para a acumulação de calor latente e flocos de grafite armazenados no mesmo para o aperfeiçoamento da condutibilidade térmica. Os flocos de grafite destacam-se por uma alta correlação e por uma alta anisotropia da condutibilidade térmica. A porcentagem volumétrica dos flocos de grafite no material acumulador térmico latente importa entre 10 e 40 %. O material composto é obtenível através da mistura dos componentes ou infiltração de uma carga contendo flocos de grafite com um material trocador de fases líquido. De preferência, os flocos de grafite ao serem misturados com o material trocador de fases mediante sacolejamento, compressão ou semelhantes é orientado de forma tal, que a condutibilidade térmica é maximizada na direção favorável para a respectiva aplicação.
