Abstract

The invention discloses a radiation refrigeration structure. The radiation refrigeration structure comprises a radiation refrigeration layer and a protective layer, wherein the radiation refrigerationlayer is provided with a high-low fluctuating first surface, the protective layer is arranged above the first surface, and the outer surface of the protective layer is a flat second surface. According to the radiation refrigeration structure, one side of the radiation refrigeration layer is arranged to be the heaving surface, so that the surface area of the radiation refrigeration layer is increased; and even more radiation refrigerating bodies in the radiation refrigerating layer are opposite to the atmosphere, so that the radiation refrigerating efficiency of the unit area is increased; andthe protective layer with a flat outer surface is arranged on the high-low fluctuating radiation refrigerating layer, so that the flowing of hot air on the surface of the radiation refrigeration layer can be avoided, the heat on the surface of the radiation refrigeration layer caused by heat convection is avoided, and the high refrigeration efficiency of the radiation refrigeration structure is further ensured.

Description

technical field [0001] The invention relates to the technical field of radiation refrigeration, in particular to a radiation refrigeration structure. Background technique [0002] Radiation refrigeration technology, as a means of temperature regulation without energy consumption, has good practicability and can enable human beings to develop harmoniously in terms of environmental protection and energy utilization, and will bring about major changes in the energy field. [0003] Any object whose temperature is higher than absolute zero will produce electromagnetic radiation. With the different conditions such as the material, molecular structure and temperature of the radiating object, the wavelength of the radiation is also different. In the infrared radiation band, in terms of the nature of radiation, when the atoms or atomic groups in a molecule change from a high-energy vibration state to a low-energy vibration state, infrared radiation in the 2.5 μm to 25 μm band is gen...
