Patent ID: 7800908

Claim:
An apparatus with a heat source comprising at least one electric or electronic component, with a heat sink and with an intermediate layer made of a thermally conductive material provided between the heat source and the heat sink, wherein the intermediate layer consists of an organic matrix with embedded nanofibers, the length of at least a majority of the nanofibers embedded in the organic matrix is between 1-100 μm and wherein the heat source and the heat sink bear with thermally conductive surfaces against the intermediate layer with a surface pressure between approximately 0.1 and 100 bar, wherein the organic matrix is already in the viscous or liquid state at a temperature between 10 and 30° C. and is in the viscous state or the liquid state at an operating temperature of the apparatus higher than 30° C. or at a temperature between 40° C. and 80° C.; and wherein the percentage of nanofibers in the matrix is between 5 and 20 percent by weight in relation to the total mass of the intermediate layer, and wherein a length/thickness ratio of a majority of the nanofibers embedded in the organic matrix is greater than 10, and wherein the thickness of the intermediate layer is between 0.01 mm and 0.5 mm.
