Heat dissipation

Definition

Heat dissipation is the process by which excess heat generated by a device or system is released into the surrounding environment to maintain optimal operating temperatures. In the context of computing, managing heat dissipation is crucial for maintaining performance and longevity of components, especially in high-speed systems. Effective heat dissipation techniques help reduce thermal stress and prevent overheating, which can adversely affect reliability and efficiency.
