The state of Sb-Te chalcogenides changes, and reversible change can also occur for bulk thermal conductivity constants.
The present invention provides a kind of controllable stealthy cape of heat based on multilayer chalcogenide.The controllable heat of the three-dimensional is stealthy
Cape covers shell by the surface that chalcogenide forms and realizes.Wherein, covering shell in surface is multiple chalcogenide rings
Superposition is constituted layer from bottom to top, by controlling the crystallization degree of chalcogenide in different circular layers, can make every layer it is corresponding different
Bulk thermal conductivity constants, obtain the stealthy required three-dimensional thermal conductivity distribution of heat, and then make hot-fluid around behind cape region, temperature field and
Thermoisopleth restores original distribution, realizes the stealthy function of heat.Meanwhile passing through the crystalline substance of chalcogenide in each circular layer of loop control
Change-anti-crystallization process, realizes the real-time ON/OFF performance of the stealthy cape of heat, lacking to overcome that the stealthy cape of heat cannot switch
Point.The present invention is based on chalcogenide crystallization-anti-crystallization principles, can effectively save energy, extend pseudo- ETL estimated time of loading；It is realizing
On, using the widely used device such as electricity, light-operated switch, the complexity and cost of the stealthy cape of heat are significantly reduced, is actually answered
It is big with potentiality.Using the technology of the present invention, the stealthy cape of calorifics can be made to be closed in most of time (i.e. not hidden
Body), so that other side is detected some invalid calorifics information, and open the stealthy function of heat when needed and allow other side's detection less than it
Thermal signals effectively hide various important informations, benumb enemy, and so that us is taken action has emergentness.The technology can make computer
Chip high efficiency and heat radiation, to improve computer performance；It realizes heat illusion, confuses infrared detector；Simultaneously spacecraft return capsule,
There is huge applications value in the equipment such as satellite.
