论文摘要
电子技术的技术进步通常需要在越来越积极的环境中使用，例如快速热循环和高功率密度。热二极管似乎是极好的候选者，可以保护关键的电子组件并确保耐用性和可靠性。我们对跨正方板的热传输进行建模，其孔受到振荡的外部温度，这种空间和时间对称性被损坏。我们发现强烈取决于孔的频率和几何形状的热电流的校准。该系统作为热二极管的行为，可以用作热结构的一部分，以在循环温度条件下散发热量。
Technological progress in electronics usually requires their use in increasingly aggressive environments, such as rapid thermal cycling and high power density. Thermal diodes appear as excellent candidates to thermally protect critical electronic components and ensure durability and reliability. We model the heat transport across a square plate with a hole subjected to an oscillating external temperature, such spatial and temporal symmetries are broken. We find rectification of the heat current that strongly depends on the frequency and the geometry of the hole. This system behaves as a thermal diode that could be used as part of a thermal architecture to dissipate heat under cycling temperature conditions.
