Technical field
The utility model relates to refrigeration technology field more particularly to a kind of radiation refrigeration covers.
Background technique
Most widely used refrigeration modes are mechanical refrigeration mode in production and living, will be electric by refrigeration systems such as compressors
It can be converted into cold energy, refrigerator and air-conditioning etc. are all made of this mode.This mode expends that electricity is larger, and the fluorine benefit largely used
High working medium not environmentally, endangers atmospheric ozone layer larger.
Radiation refrigeration belongs to passive refrigeration modes, does not expend electric energy, and no working medium is non-hazardous to environment, passes through atmospheric window
Radiation refrigeration is of great significance for energy conservation and environmental protection.Atmospheric window refers to that solar radiation is not reflected, absorbed by atmosphere
With scattering those of the high light radiation wavelength band of transmissivity.The infrared light spectral coverage of atmospheric window is 8-13 microns, ground object
The electromagnetic wave of the infrared light spectral coverage of sending is directly entered -270 DEG C of space of cold space through atmosphere, thus by the heat of object
It takes away, realizes refrigeration cool-down.Domestic and international researcher uses various method enhanced rad refrigerating capacities.
The method of radiation refrigeration ability enhancing is to try to reduce the solar radiation that body surface absorbs, while enhancing as far as possible
The infrared emission of infrared light spectral coverage.Common body surface is difficult to be provided simultaneously with the two performances or sun absorption is larger, or

Method is relatively simple, general using material emit sun light intensity (such as silver-plated or aluminize) realization.It is more multiple to enhance infra-red radiation
It is miscellaneous, it has been found that surface micro-nano structure can be very big with electromagnetic wave coupling (such as surphon excimer, microcavity resonance effect)
Enhance the infrared emittance of certain spectral.Enhance atmospheric window infrared spectroscopy by artificial nano material or surface Meta Materials
The infrared emittance of section.Australian Si Weiben University of Science and Technology proposes a kind of anisotropic cone cell matrix surface texture, enhancing
Atmospheric radiation window broadband infrared radiates, and the refrigeration work consumption of 116.6W/m2 is realized under atmospheric environment.This micro-nano processing method at
This valuableness, complex process, it is difficult to realize large-scale production and application.It is thin that Univ Colorado-Boulder USA has developed a kind of macromolecule
Film, it is silver-plated in film surface by embedding microsphere particle on film, realize radiation refrigeration, it is final to realize direct sunlight condition
Lower refrigeration work consumption about 93W/m2.But this embedded microsphere particle is very high to requirements such as circularity, the particle homogeneity of microballoon, price
It is expensive.
Although outdoor tent, automotive sewing car cover etc. have certain heat-insulated and sunshade effect, still more much higher than temperature, it is not achieved
The effect of refrigeration cool-down.
