Simple Measuring Method of Thermal Conductivity of Silicone Grease and Effect of Carbon Nanomaterials on Its Thermal Conductivity

In the electronic equipment like personal computers with high heat fluxes for instance, the thermal contact resistance plays an important role in its cooling system. To attain high cooling performance, some kind of grease is often introduced between a heat source and a heat sink. In the present study, a simple method for thermal conductivity measurement of grease has been proposed and confirmed its validity by using greases with known thermal conductivity. From a series of measurements, the validity of the present measuring method has been confirmed. Further, the effect of the addition of carbon nanomaterials on the thermal conductivity of silicone grease has been investigated, and its quantitative relation has been clarified.
