The concept of phase change material (PCM) is simple: they are substances that absorb and release large amounts of heat during the process of changing their phase (e.g. from solid to liquid or vice versa). These substances melt and solidify at specific, defined temperatures, making them suitable for a wide range of thermal management applications. Thermal management with phase change materials can be challenging, as their various forms may have inadequate thermal conductivity on their own. Although it may seem counterintuitive, the use of these unique materials, combined with expert heat sink engineering, can create incredibly effective thermal management solutions.
How are heat sinks made of phase change materials used for thermal management?
