Description

Additive for thermal management fluid and thermal management fluid composition comprising same Technical Field The present disclosure relates to an additive for a thermal management fluid and a thermal management fluid composition including the same. Background A thermal management fluid (THERMAL MANAGEMENT fluid) is a fluid used to efficiently transfer and control heat, primarily for cooling and heating systems. The coolant functions to reduce the temperature of the heat source by absorbing heat generated from the heat source. Substances which have high thermal efficiency, low viscosity, low cost, are non-toxic, chemically stable, and do not cause corrosion of the apparatus are preferred as coolants. With the high performance of various electronic products such as electric vehicles, the electronic products generate more heat during use. Controlling the heat generated by the product is a necessary consideration for smooth use of the product and preventing the life of the product from being shortened. Immersion cooling (Immersion cooling) is one of the cooling methods used for thermal management of electronic devices and computer systems. Since the immersion cooling is performed by directly cooling the electronic device with a fluid, heat can be removed more effectively than in the conventional air cooling method or water cooling method.
