摘要

应用微分几何方法可以优化圆柱扩散器的抽热效率[j]。黄，理论热学:热超材料的转换热学和扩展理论(b施普林格，2020)]，以找到一种超材料设计。这可以通过将隔热材料(聚四氟乙烯)与高导热材料(铜)耦合来实现，其中热流是定向的。通过控制等温等温线之间的距离，以提取热量，同时保持沿扩散器恒定的温度梯度，避免热量积聚。

Metamaterials simulation for thermal diffusers

The heat extraction efficiency of a cylindrical diffuser can be optimized by applying differential geometry [J.-P. Huang, Theoretical Thermotics: Transformation Thermotics and Extended Theories for Thermal Metamaterials (Springer, 2020)], in order to find a metamaterial design. That can be done by coupling a thermally insulating material (polytetrafluoroethylene) with a high thermal conductivity material (copper) where the heat flow is directed. By controlling the distance between the isothermal contours, to extract the heat while maintaining a constant temperature gradient along the diffuser avoiding heat accumulation.
