Abstract

Compositions de fluides présentant une conductivité thermique améliorée, supérieure jusqu'à 250 % à leurs analogues traditionnels et procédés de préparation de ces fluides. Les compositions contiennent au minimum un milieu fluide tel que l'huile ou l'eau et une quantité efficace sélectionnée de nanomatériaux de carbone, nécessaires pour améliorer la conductivité thermique du fluide. Un des nanomatériaux de carbone préférés est un graphite à conductivité thermique élevée, sa conductivité thermique étant supérieure à celle du fluide pur qui est dispersé à l'intérieur dudit matériau avec une conductivité thermique et concassé, broyé ou préparé de façon naturelle avec une granulométrie moyenne inférieure à 500 nm, et de préférence moins de 200 nm, et si possible moins de 100 nm. Le graphite est dispersé dans le fluide au moyen d'un ou de plusieurs procédés, y compris l'utilisation d'ultrasons, le concassage et la dispersion chimique. Une autre source préférée de nanomatériau à base de carbone est le nanotube de carbone avec une structure graphitique; toutefois, d'autres nanomatériaux à base de carbone sont également acceptables. Pour conférer une plus grande stabilité au matériau, on choisira un ou plusieurs dispersants chimiques. L'amélioration de la conductivité, en comparaison au fluide sans nanomatériau de carbone, est à peu près proportionnelle à la quantité de nanomatériaux à base de carbone (nanotubes de carbone et/ou de graphite) ajoutés.
