👉 The thread fluid, also known as the cooling fluid or coolant, is a specialized liquid used in various systems to manage heat and maintain optimal operating temperatures. It circulates through channels or passages within components like CPUs, GPUs, and power electronics, absorbing heat generated by these parts and transferring it to a heat exchanger or radiator where the heat is dissipated into the surrounding environment. This fluid typically has high thermal conductivity and low viscosity to ensure efficient heat transfer while minimizing pumping power requirements. Common types include water-glycol mixtures, mineral oils, and synthetic fluids, each chosen based on the specific thermal and operational demands of the application.
