When a material undergoes a phase change such as a solid turning into a liquid, generally energy is absorbed by the material in order to change from a solid to a liquid. This energy absorption, at the phase change point, can be utilized to enhance a heat sink capacity during transient events to control the temperature rise in an electronic component. Phase-change materials (PCM) can be incorporated into a heatsink to provide the additional energy absorption and heat dissipation during these transient thermal events in electronic components to allow for great operating range.

当材料发生相变（例如固体变成液体）时，通常材料会吸收能量以从固体变为液体。这种在相变点的能量吸收可用于在瞬态事件期间增强散热能力，以控制电子元件中的温升。相变材料 (PCM) 可以结合到散热器中，以在电子元件中的这些瞬态热事件期间提供额外的能量吸收和散热，从而实现更大的工作范围。
