Radiation heat flow regulation and control device and application thereof

The invention belongs to the technical field of thermal radiation, and particularly relates to a radiation heat flow regulation and control device and application thereof. The radiation heat flow regulation and control device comprises at least two radiation bodies which are oppositely arranged, and each radiation body comprises a radiation layer; the at least one radiator includes a substrate and one or more organic polymer layers, where the organic polymer layers are located between the substrate and the radiation layer to reduce radiation absorption of materials other than the radiation layer. The radiation spectrum mismatch between the organic polymer layer and the radiation layer can effectively reduce the heat energy absorbed by the substrate or other materials so as to establish an efficient heat radiation channel, and the efficient heat radiation channel is beneficial to improving the heat rectification ratio of the heat rectification device and improving the output power and energy conversion efficie
