Abstract
L'invention concerne un matériau de transfert de chaleur poreux, souple et élastique comprenant un réseau de flocons métalliques. De tels matériaux de transfert de chaleur sont, de préférence, obtenus, dans un premier temps, par formation d'une pâte conductrice comprenant un solvant volatil organique et des flocons métalliques conducteurs. La pâte conductrice est chauffée à une température inférieure au point de fusion des flocons métalliques, évaporant ainsi le solvant et frittant uniquement les bords des flocons qui sont fusionnés aux bords de flocons adjacents, de manière que des pores ouverts soient définis entre au moins quelques flocons parmi les flocons adjacents, formant ainsi un réseau de flocons métalliques. Grâce à cette structure en réseau, le matériau de transfert de chaleur présente aussi bien un faible module de stockage inférieur à environ 10 Gpa que de bonnes propriétés de résistance électrique.
