Active cooling systems

Definition

Active cooling systems are technologies designed to actively remove heat from a system, typically through the use of coolant fluids and heat exchangers. These systems play a crucial role in maintaining optimal operating temperatures for equipment that is exposed to high-energy environments, such as plasma devices. By effectively managing heat, active cooling systems help prevent damage to components and ensure the efficiency and longevity of energy-intensive operations.
