In the working state day and night, routers will constantly generate heat. Proper use of thermal conductive materials can ensure heat dissipation while increasing stability. Thermal pad is added between the radiator and the metal shielding cover to fill the gap. Its soft and compressible properties can cover uneven surfaces, reduce interface thermal resistance, and achieve better heat dissipation effect. Thermal pad play a crucial role in the heat dissipation of routers due to their excellent thermal conductivity and compressibility.
