Thermal deception method and thermal deception structure

Abstract

According to the thermal deception method and the thermal deception structure, a directional heat conduction structure composed of a high-heat-conductivity material and a low-heat-conductivity material which are distributed according to a specific rule is introduced above an actual object plane where a heat source (object) is located, and the directional heat conduction structure can directionally guide heat flow generated by the heat source on the actual object plane, therefore, a special thermal phantom is generated on an emergent surface (namely an observation image plane) of the directional heat conduction structure. Compared with an actual heat source, the number, the position, the size, the shape and other characteristics of the thermal illusion can be regulated and controlled by designing the heat conduction direction of the directional heat conduction structure, and then the pre-designed thermal deception effect can be achieved.

Description

technical field [0001] The invention belongs to novel thermal deception technology, in particular to a thermal deception method and a thermal deception structure. Background technique [0002] Thermal Camouflage is a new type of thermal phantom device proposed with the development of thermal metamaterials and transformation thermodynamics. When the heat flow conducts on the isotropic and uniform heat-conducting material plane, the thermal diffusion rate of the heat flow along all directions is the same, and the distribution of the temperature field is also uniform after reaching thermal equilibrium. However, if there are some other objects with different thermal conductivity on the heat conduction plane, the temperature field distribution after reaching thermal equilibrium will no longer be uniform. At this time, outside observers will "perceive" through the temperature field distribution that there are other objects on the heat conduction plane. object. To achieve thermal...
