摘要
Disclosed 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. More particularly, the present disclosure relates to a heat-dissipation fluid composition including 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 is 850 cP or more, and a viscosity at 30 °C is 750 cP or less, a method of preparing the heat-dissipation fluid composition, and a battery module and battery pack including the heat-dissipation fluid composition. In accordance with the present disclosure, a heat-dissipation fluid composition that 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 in a heat-dissipation fluid including the 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 are provided.
