现今电子装置的运作功能日益复杂，因而需要设置众多高性能的零组件以实现其装置功能。然而，高性能零组件通常是在高功率状态下运作，如此会伴随大量的热能产生，而导致电子装置的温度提高。此外，电子装置的轻薄化发展趋势，也使得电子装置特定部位产生的热能不易散逸。因此，在电子装置内部的特定零组件如处理芯片、电源模组、电池模组处常会发生局部过热问题，而影响装置效能，严重的甚至可能会导致零组件毁损、起燃的问题发生。The operational functions of today's electronic devices are becoming more and more complex, so many high-performance components need to be provided to realize the device functions. However, high-performance components usually operate in a high-power state, which results in a large amount of thermal energy being generated, resulting in an increase in the temperature of the electronic device. In addition, the trend of thinning and lightening of electronic devices also makes it difficult for the heat energy generated in specific parts of the electronic device to dissipate. Therefore, local overheating problems often occur in specific components inside electronic devices, such as processing chips, power modules, and battery modules, which affect device performance, and may even lead to component damage and ignition problems.
