Specifically, the radiation refrigeration coating 4 includes at least one high-reflectivity inorganic particle and at least one high molecular polymer, and the surface of the radiation refrigeration coating 4 includes hydrophilic regions 401 and hydrophobic regions 402, and the hydrophilic regions 401 and the hydrophobic regions 402 are arranged in a staggered manner.
Specifically, the inorganic particles having high reflectance are preferably one or more of zirconium oxide, hafnium oxide, calcium carbonate, aluminum oxide, titanium oxide, barium sulfate, and the like;
specifically, the high molecular polymer is preferably one or more of PTFE, PVDF, PEVE, NMP, and the like;
specifically, the radiation refrigeration coating 4 has a desert beetle bionic structure, the surface of the radiation refrigeration coating is formed by combining hydrophilic areas 401 and hydrophobic areas 402 in a staggered manner, and the hydrophilic areas 401 can condense water vapor into small water drops under the action of passive radiation refrigeration;
specifically, the hydrophobic region 402 collects the small water droplets to the fresh water storage chamber; avoid scraping through the manual work and get the collection comdenstion water, improve condensation efficiency.
Specifically, the heating of the seawater or the soil is completed through the photothermal conversion of sunlight, the condensation is refrigerated through passive radiation, the heat is radiated to the low-temperature universe while the sunlight is reflected, and the temperature of the condensation chamber 2 is reduced to be lower than the dew point temperature; more importantly, the bionic structure design of the radiation refrigeration coating 4 enables the radiation refrigeration coating to have higher condensed water collection efficiency compared with the traditional method.
In the present embodiment, the reflectance of the radiation refrigeration coating 4 in the visible band is greater than 0.9, an
Specifically, the emissivity of the radiation refrigeration coating 4 in the mid-infrared atmosphere transparent window waveband is greater than 0.9.
Specifically, as shown in fig. 5, fig. 5 is a reflectivity of the radiation refrigeration coating 4 in the visible near infrared, which illustrates that the coating has a reflectivity of 0.9 or more in the visible near infrared band, especially in the strong sunlight band of 400-700 nm.
Specifically, as shown in fig. 6, fig. 6 shows the emissivity of the radiation refrigeration coating in the mid-infrared range of 2-20 microns, illustrating that the coating has an average emissivity of above 0.9 in the mid-infrared atmospheric transparent window band.
In this embodiment, the radiation refrigeration coating 4 is inclined to one side to form a height difference, and an included angle between the radiation refrigeration coating 4 and a horizontal plane is 0 to 45 degrees, so that condensed water drops can slide from the radiation refrigeration coating 4, and manual scraping and collection are not needed.
Specifically, the two-dimensional bionic surface treatment with hydrophilic and hydrophobic areas staggered is carried out on the surface of the radiation refrigeration coating in the condensation chamber, so that condensed water on the surface of the radiation refrigeration coating is easy to gather and can spontaneously break away from the surface, and the problem that fresh water at a condensation end in the current evaporation and condensation system is difficult to gather and can be collected only by additionally consuming manpower or electric power is solved.
Specifically, the staggered arrangement mode of the hydrophilic areas and the hydrophobic areas can overcome the problem of overlarge or undersize surface tension, so that the condensation and the falling off of water drops can be realized simultaneously.
Specifically, when the surface of the radiation refrigeration coating in the condensation chamber is subjected to two-dimensional bionic surface treatment with hydrophilic and hydrophobic areas staggered, the included angle between the radiation refrigeration coating and the horizontal plane is 30-45 degrees, so that liquid drops can flow on the surface of the radiation refrigeration coating.
Specifically, when the surface of the radiation refrigeration coating in the condensation chamber is subjected to three-dimensional bionic surface treatment with hydrophilic and hydrophobic areas staggered, the included angle between the radiation refrigeration coating and the horizontal plane is 10-30 degrees, so that liquid drops can flow on the surface of the radiation refrigeration coating. It should be noted that the smaller the tilt angle of the radiation refrigeration coating, the better the refrigeration effect, but the adverse effect on water drop rolling; when the two-dimensional bionic surface is adopted, the required angle is large, so that water drops can roll off easily; after the three-dimensional bionic surface is made, water drops can roll down along a slope body (please refer to fig. 7, a hydrophilic area of the three-dimensional bionic surface of the radiation refrigeration coating is a semicircular slope body), so that the inclination angle of the radiation refrigeration coating is set to be smaller as much as possible.
Specifically, referring to fig. 7, the surface of the radiation refrigeration coating in the condensation chamber is subjected to three-dimensional bionic surface treatment with interlaced hydrophilic and hydrophobic regions, so as to further increase the condensed water collection efficiency of the coating. The method comprises the following steps of (1) obtaining a semi-circular slope-like body higher than a plane on an original coating by using the same type of slurry of a radiation refrigeration coating as a raw material and using methods such as silk-screen printing, 3D printing, mesh spraying and the like; the surface of the slope body is subjected to hydrophilic treatment, the diameter of the plane circle is 0.5mm-1mm, the height of the slope body is the same as the diameter of the circle, and the slope forms an inclination angle for the rolling of the liquid drops, so that the liquid drops are favorably separated from the surface and roll down to a bottom hydrophobic area along the slope. Wherein, the distance between the slope bodies is 0.5mm-1.5mm, which is beneficial to the accumulation of small drops among each other to form large drops as soon as possible and the accelerated rolling; the placing angle of the radiation refrigeration coating and the plane form 10-30 degrees, which is beneficial to the coating to achieve the maximum refrigeration effect.
Specifically, referring to fig. 8, the contact angle less than 10 ° is super-hydrophilic (the contact angle is labeled as 0 °), which illustrates that the hydrophilic region has super-hydrophilicity and has the ability to condense water droplets in the region.
Specifically, referring to fig. 9, the contact angle greater than 120 ° is super-hydrophobic (the contact angle is labeled as 137.6 degrees in the figure), which indicates that the hydrophobic region has super-hydrophobicity and the ability of causing the water droplet to roll spontaneously in the region.
Specifically, the thickness of the radiation refrigeration coating 4 is 20-150 μm.
Specifically, the thickness of the radiation refrigerating coating 4 is preferably 20 to 60 μm. The thickness of the radiation refrigeration coating 4 is 20-150 μm, which is beneficial to avoiding the transmission of sunlight and increasing the reflection; radiation cooling coatings 4 below 20 μm can cause sunlight penetration and radiation cooling coatings 4 above 150 μm can result in excess material.
In this embodiment, the ratio of the inorganic particles to the high molecular polymer is not less than 3: 2; and
the particle size of the inorganic particles is 0.4-2 μm.
Specifically, the particle size of the inorganic particles is preferably 0.4 to 2 μm, which is advantageous for scattering with sunlight and increasing reflection (the improvement of reflection effect is not significant if the particle size is not within this range).
Specifically, when the ratio of inorganic particles to high molecular weight polymer was 3: 2, as shown in FIG. 4, the air averaged 47.49 degrees and the radiation refrigeration coating 4 averaged 42.19 degrees. The radiation refrigeration coating 4 has a cooling effect of about 6 degrees lower than that of air, which indicates that the surface temperature of the radiation refrigeration coating 4 is far lower than that of air, and the temperature difference required by condensed water vapor is sufficiently provided, so that the condensation efficiency is improved.
