DeHeat Solid-State Cooling Using 3D Printed, Graphene-Doped, Fractal-Like Metamaterials

DeHeat™技术是一种基于分形的固态可持续冷却解决方案。我们正在申请专利的超材料结构与“门格尔海绵”是自相似的，这是一种复杂的分形结构，虽然在数学上有定义，但以前证明不可能在所需的分辨率下制造。然而，3D打印（或增材制造）和选择性激光烧结（SLS）的快速成熟现在允许制造这样的架构。制造过程将通过最先进的3D打印能力，特别是选择性激光烧结（SLS）。当红外辐射入射到材料上时，它被复杂的结构捕获，不能再辐射回环境中，从而产生净冷却效应。由于石墨烯涂层聚合物珠具有很高的导热性，因此将用于提高材料性能。该原理是完全可扩展的——从计算机芯片的热管理，大型数据中心的冷却和电动汽车电池——这是一项具有多种潜在应用的使能技术。这样一个系统的好处是多方面的——节约能源、保护环境和减少碳足迹（不需要氢氟碳化物）。

Inclusive Designs Ltd DeHeat™ technology is a fractal-based, solid-state sustainable cooling solution. Our patent-pending metamaterial structures are self-similar to the ‘Menger Sponge’ – a complex fractal construct that while mathematically defined, has previously proved impossible to fabricate at the required resolution. However, the rapid maturation of 3D printing (or additive manufacturing) and selective laser sintering (SLS) now allows for such architectures to be fabricated. The manufacturing process will be via state-of-the-art 3D printing capabilities, in particular, selective laser sintering (SLS). When infrared radiation is incident upon the material it is captured by the complex structure and cannot re-radiate back into the environment, resulting in a net cooling effect. Graphene-coated polymer beads will be used to enhance the material performance due to the very high thermal conductivity. The principle is completely scalable – from thermal management of computer chips, large data centre cooling and electric vehicle batteries - it is an enabling technology with multiple potential applications. The benefits of such a system are many-fold –making energy savings, protecting our environment and reducing carbon footprint (no HFCs required).
