Abstract

Método de fabricación de un disipador térmico poroso para dispositivos electrónicos utilizando técnicas computacionales de diseño asistido por ordenador basadas en un método basado en diagramas de Voronoi. El disipador térmico poroso obtenido se caracteriza por poseer macroporosidad variable e interconectada. Dicha macroporosidad se establece a partir de la definición del espesor trabecular de sección no constante (Tb.Th), de la separación trabecular (Tb.Sp), del número de puntos de nucleación de Voronoi y del volumen de la zona a rellenar. Dicho disipador térmico poroso se fabrica a partir de técnicas aditivas por impresión tridimensional (3D) con materiales conductores. Esta invención es aplicable en el campo dedicado a la fabricación de disipadores o intercambiadores de calor encargados de la evacuación de calor desde un elemento con elevada temperatura hacia un medio con menor temperatura con o sin circulación forzada de aire. Su elevada superficie específica y la posibilidad de conformarlo adaptándolo a un volumen predefinido permite optimizar la evacuación de calor en espacios reducidos.
