Abstract
The invention provides a combined type heat dissipation device which comprises an electromagnetic radiation heat dissipation structure, the electromagnetic radiation heat dissipation structure comprises a polarization material, the polarization material is composed of a plurality of polarization material units, each polarization material unit is provided with an optical phonon, and the polarization material can interact with solar radiation and thermal radiation. The solar radiation interacts with the surface of the polarization material unit to generate diffuse reflection, the thermal radiation interacts with the optical phonons, and the optical phonons gain the energy intensity of the thermal radiation.
