👉 The amplifier fluid, also known as a coolant or working fluid in power electronics, is a specialized liquid used to manage heat in electronic devices such as inverters and motor drives. It circulates through the system, absorbing excess heat generated by components like transistors and capacitors, then dissipating this heat through a radiator or heat sink to maintain optimal operating temperatures. This fluid is crucial for ensuring the longevity and efficiency of electronic systems by preventing overheating, which can lead to performance degradation or failure. The fluid's properties, such as thermal conductivity and viscosity, are carefully selected to balance heat transfer efficiency with pumpability and chemical stability.
