We adapt tools of transformation optics, governed by a (elliptic) wave equation, to thermodynamics, governed by the (parabolic) heat equation. We apply this new concept to an invibility cloak in order to thermally protect a region (a dead core) and to a concentrator to focus heat flux in a small region. We finally propose a multilayered cloak consisting of 20 homogeneous concentric layers with a piecewise constant isotropic diffusivity working over a finite time interval (homogenization approach).
我们将由（椭圆型）波动方程支配的变换光学工具应用于由（抛物型）热方程支配的热力学。我们将这一新概念应用于一个隐形斗篷，以便对一个区域（一个死核）进行热保护，并应用于一个集中器，以在一个小区域内聚焦热通量。我们最终提出了一种由20个均匀同心层组成的多层斗篷，其具有分段常数各向同性扩散率，在有限时间间隔内起作用（均匀化方法）。
