Beschreibung
Zusammenfassung:	The present invention relates to a method of heat transfer between a metallic or non-metallic item and a heat transfer fluid comprising a fluid medium, hydrophobic nanoparticles having a lateral size between 26 and 50µ?? and a dispersing agent, wherein the nanoparticles concentration / dispersing agent concentration ratio in weight is between 3 and 18 and wherein nanoparticles do not comprise carbon nanotubes. La présente invention concerne un procédé de transfert de chaleur entre un élément métallique ou non métallique et un fluide de transfert de chaleur comprenant un milieu fluide, des nanoparticules hydrophobes ayant une taille latérale comprise entre 26 et 50 µm et un agent dispersant, le rapport entre la concentration de nanoparticules et la concentration d'agent dispersant étant compris entre 3 et 18 et les nanoparticules ne comprenant pas de nanotubes de carbone.
