Abstract
Provided are a heat-dissipation fluid composition, a method of preparing the heat-dissipation fluid composition, and a battery module and battery pack including the heat-dissipation fluid composition. The heat-dissipation fluid composition can include 100 parts by weight of a nonconductive oil; 1 to 30 parts by weight of thermally conductive inorganic particles; and 1 to 30 parts by weight of an inorganic precipitation inhibitor, wherein a viscosity at 20° C. and 50 rpm is 850 cP or more, and a viscosity at 30° C. and 50 rpm is 750 cP or less. The heat-dissipation fluid composition exhibits excellent electrical insulating properties and thermal conductivity and, especially, excellent heat dissipation performance even after long-term use because thermally conductive inorganic particles are not permanently precipitated during use.
