Description of the invention: [Technical field to which the invention pertains] The present invention relates to a solar collector. [Prior Art], (4) ^ The development of society, the human society has strengthened resources and energy. It is well known that the resources and energy systems on the earth are limited. Therefore, in various economic, political and scientific research activities, the issue of resources and energy has become a top priority. And because some of the resources can be recycled through some people's processes, the problem of 'energy' is more prominent. Solar energy is the most abundant energy available to humans, and it is also the cheapest, cleanest, and most promising source of energy. Solar cells and solar collectors are the primary means of direct utilization and absorption of solar energy. Compared with solar cells, the efficiency of solar heat collection n is much higher than that of other solar energy sources. However, due to the limitations of structure and materials, solar collectors are still narrow in scope and field of application.太阳能 Widely used solar collectors are divided into solar tube type vessels (please refer to “Comparison of vacuum tube solar domestic water heaters and their east placement”, Journal of Solar Energy, Wu Jiaqing, etc., ν〇19, Ρ396-405 (1988) )) and solar panel collectors. Referring to the drawing, the solar tube collector 300 of the prior art includes a seat body 30 placed on the ground, a water storage bucket 32 mounted on the side of the seat body 30, and a connecting body 30. A vacuum heat absorbing tube 34 between the other side and the water storage tank 32. When the vacuum heat absorbing tube 34 receives the solar energy, the cold water flow and the hot water rise phenomenon are generated by utilizing the principle that the cold water is more important than the hot water, so that the liquid in the vacuum heat absorbing tube 34 of the above-mentioned 2009200943 is convected by natural convection. , with = good temperature. However, when the sunlight is irradiated onto the circular tube curve of the heat absorbing tube 34 of the vacuum suction tube 34, it is necessary to (4) clean, return, and maintain a good hot material formation, which is time consuming and laborious. The advent of solar panel collectors overcomes the problems that arise in the solar tube 300. Referring to FIG. 2, the solar panel collector 500 of the prior art includes an upper substrate 5, a lower substrate 52, a frame holder 56, and a plurality of supports 58. The upper substrate 5 is a transparent substrate and is made of a transparent material such as glass or plastic. The lower substrate 52 is a heat absorbing plate, made of a material such as copper, aluminum alloy (preferably rustproof aluminum), stainless steel, zinc or the like. The upper substrate 50 and the lower substrate 52 constitute a cavity 60, and the frame holder 56 is provided on both sides of the cavity 6''. A plurality of supports 58 are disposed between the upper substrate 50 and the lower substrate 52. ❹ However, in order to prevent the lower substrate 52 from being oxidized during the preparation process, the lower substrate 52 needs to be prepared in a high vacuum adiabatic environment, and is heated to a higher temperature, and the production process is complicated. Therefore, the cost in the preparation process of the lower substrate 52 is made higher, so that the cost of the solar panel collector 500 is correspondingly high, and it is not suitable for popularization and application in a large area. In addition, the lower substrate 52 itself of the solar panel type collector 500 also serves as a heat absorbing layer, so that the selection of the material of the lower substrate 52 is limited, and the heat absorbing material must be used, and the lower substrate 52 made of a heat absorbing material such as copper or aluminum alloy is used. Since the heat absorption surface area of the lower substrate 52 is small and the reflection of sunlight is larger than 200946843 ♦, the conversion efficiency to solar energy is low. In view of this, it is necessary to provide a solar collector having a high conversion efficiency and an unlimited selection of the underlying sheet material. SUMMARY OF THE INVENTION A solar collector includes an upper substrate, a lower substrate, a heat absorbing layer, a frame support, and a plurality of supports. The upper substrate and the lower substrate are disposed opposite each other. The frame bracket is disposed between the upper substrate and the lower substrate. The upper substrate, the lower substrate and the frame bracket together form a cavity. The heat sink layer is disposed on an upper surface of the lower substrate within the cavity. The plurality of supports are disposed in the cavity at intervals and are in contact with the upper substrate and the heat absorbing layer, respectively. The heat absorbing layer is a carbon nanotube composite material layer. Compared with the prior art, the solar collector has the following advantages: First, since the carbon nanotube has good heat absorption, the solar collector composite layer is used as the heat absorption layer, and the solar collector can be improved. For the energy conversion efficiency of the sun @能, the solar energy is absorbed evenly. Second, since the carbon nanotube composite layer is used as the heat absorbing layer, the selection of the material of the lower substrate is not limited. [Embodiment] Hereinafter, a solar collector of the present technical solution will be described in detail with reference to the accompanying drawings. Referring to FIG. 3 and FIG. 4, the embodiment of the present invention provides a solar energy collector 100 including an upper substrate 10, a lower substrate 12, a heat absorbing layer 14, a frame support 16, and a plurality of supports 18. The upper substrate 10 and the lower substrate 12 are disposed opposite to each other. The frame holder 16 is disposed between the substrate 10 and the lower substrate 12. The upper substrate 10, the lower substrate 12, and the side [the holder 16 form a cavity 2". The heat absorbing layer is disposed on the upper surface 121 of the lower substrate 12 located in the cavity 2G. The plurality of supports 18 are spaced apart from the cavity 2〇β and are in contact with the upper substrate ίο and the heat absorbing layer 14, respectively. The heat absorbing layer 14 includes a carbon nanotube composite layer. The upper substrate 10 is a light transmissive substrate for transmitting sunlight. The upper substrate 10 is made of a transparent material such as glass, plastic, transparent ceramic, high molecular transparent material or the like. The upper substrate 10 has a thickness of 100 μm to 5 mm, preferably 3 mm. The shape of the upper substrate 1〇 is not limited, and may be a triangle, a hexagon, a quadrangle, etc., and may be formed into an arbitrary shape according to requirements. The lower substrate 12 is disposed opposite to the upper substrate 1 . The lower substrate 12 is a heat collecting substrate 'for collecting and transmitting energy of sunlight. The lower substrate 12 may be made of glass or made of a material having a good thermal conductivity such as zinc, indium or stainless steel. The thickness of the lower substrate 12 is 1 〇〇 μm ❹ 5 5 mm', preferably 3 mm. The shape of the lower substrate 12 is not limited, and may be a triangle, a hexagon, a quadrangle or the like, and may be formed into any shape according to requirements. The frame bracket 16 may be made of a material such as glass. The height of the frame support 16 is from 1 μm to 500 μm, preferably from 150 μm to 250 μm. The cavity 20 is a vacuum insulation environment, which suppresses the natural convection of the air, thereby reducing the loss of convective heat transfer in the solar collector 100, and maintaining the heat, thereby greatly improving the heat of the solar collector 100. 200946843 Efficiency. In addition, the cavity 20 may not be in a vacuum environment, and the cavity 20 may be filled with a spacer layer (not shown) capable of transmitting light and being insulated. The spacer layer fills the entire cavity and may be Transparent foam-type materials such as heat-resistant plastics can also be used as a spacer layer by using a less thermally conductive gas such as nitrogen. The heat absorbing layer 14 comprises a carbon nanotube composite layer comprising a plurality of carbon nanotubes and a black opaque material. The black opaque material is carbon particles or graphite milk. The carbon nanotubes are randomly arranged and uniformly distributed in the layer of the carbon nanotube composite material. The mass percentage of the carbon nanotubes in the carbon nanotube composite layer is 8〇%, and the mass percentage of the black opaque material is 2% or less. The preparation method of the heat absorption layer 14 in this embodiment includes the following steps: First, a carbon nanotube slurry is provided. The carbon nanotube slurry comprises a nanocarbon f, a black opaque material, and an organic vehicle. In this embodiment, preferably 5% by mole of carbon nanotubes, 20% of carbon particles, and 3% by weight of an organic vehicle. The organic oxime body includes terpineol as a main solvent, a small amount of dibutyl phthalate orthophthalic acid as a plasticizer, and a small amount of ethyl cellulose as a stabilizer. After the components are mixed in proportion, the components can be uniformly dispersed in the polymer by ultrasonic vibration to obtain a uniform and stable slurry. Then, the above carbon nanotube aggregate is applied to the upper surface 12 of the lower substrate 12 in the cavity 2G by screen printing or direct coating method and the organic carrier in the carbon nanotube (four) bucket is removed. , 14. The method of removing the organic vehicle can be (4) drying or self-drying. The carbon nanotubes in the carbon nanotube composite layer may be single-walled nanocarbons 11 200946843 • tubes, double-walled carbon nanotubes or multi-walled carbon tubes. When the carbon nanotubes in the carbon nanotube composite layer are single-walled carbon nanotubes, the diameter of the single-walled carbon nanotubes is from 0.5 nm to 50 nm. When the carbon nanotubes in the carbon nanotube composite layer are double-walled carbon nanotubes, the double-walled carbon nanotubes have a diameter of nanometers to 50 nanometers. When the carbon nanotubes in the carbon nanotube composite layer are multi-walled carbon nanotubes, the diameter of the multi-walled carbon nanotubes is 15 nm to 5 Å. The carbon nanotube composite layer includes The black nano-material is the carbon nanotube, the carbon nanotube has good absorption characteristics and high thermal conductivity. The nano-carbon composite layer has good absorption properties for sunlight. . The nano carbon tube composite material layer can be prepared by screen printing or direct coating method, and the preparation method is simple, the cost is low, and the utility model is suitable for large-area popularization and application. The solar collector 1 has a heat absorbing layer. The absorption efficiency of light increases as the thickness of the heat absorbing layer 14 increases. = 2 = The thicker the layer 14, the higher the absorption efficiency for sunlight. The heat absorbing layer 14 has a thickness of 3 μm to 2 mm. Ο The plurality of branches 18 are used to resist atmospheric pressure and enhance the robustness of the solar collector 100. The height of the support 18 is the same as the height of the side frame bracket 16. The support 18 is made of a material that is less heat absorbing, such as glass. The shape of the support 18 is not limited and may be a bead shape or a filament shape. The solar collector 100 is a flat type structure. In addition, the solar collector 100 can be formed into various other shapes, such as a cylindrical surface, a spherical surface, and the like. The solar collector 100 can be widely applied to the outer wall of a building structure to achieve heating of the interior of the building. 12 200946843 > * The upper substrate 1 〇 and the lower substrate 12 of the solar heat collecting HUH can be conveniently formed into various shapes to serve as a decoration. The positron collector 100 further includes a reflective layer 22 disposed on the lower surface 101 of the upper substrate 1 空腔 in the cavity 2 ' having a thickness of 10 nm to 1 μm... An ideal solar collector 100 should be able to absorb solar energy from the surface of the human body to the maximum extent, while at the same time reducing its own radiant heat loss, so as to maximize the conversion of solar energy into heat. The solar heat collection means that the reflectance of the visible light and the near-infrared light band is low, that is, the absorption ratio is high, and the reflectance is high in the medium and far red light bands, that is, the emissivity is low. This requires a reflective layer 22 to be disposed within the solar collector 100. The reflective layer 22 is an infrared reflective layer, such as an indium tin oxide film or a carbon nanotube structure. The carbon nanotube structure comprises a disordered carbon nanotube layer, an ordered carbon nanotube layer or a carbon nanotube composite layer. The reflective layer 22 is transparent to visible light and near-infrared light, and has excellent characteristics of transmitting visible light and near-infrared light, and reflecting medium and far-reaching = external light, thereby reducing the solar collector 100 to solar energy. The radiation loss of energy increases the energy conversion efficiency of the solar collector 100 to solar energy. The reflective layer 22 and the heat absorbing layer 14 may both be carbon nanotube structures, but the thickness of the reflective layer 22 is smaller than the thickness of the heat absorbing layer 14 to ensure that most of visible light and near-infrared light pass through the reflection. Layer 22. Further, a circulating fluid layer 24 may be disposed on the lower surface 122' of the lower substrate 12 of the solar collector 100, such as a lower temperature water or a liquid such as ethylene glycol as a circulating liquid. The solar collector 100 can be used to directly use water as hot water, or to take heat away as other 'applications' such as seawater desalination, refrigeration, power generation, and the like. The solar collector 100 is irradiated to the heat absorbing layer 14 after the sunlight passes through the light-transmitting upper substrate 10. Since the heat absorbing layer comprises a tired color nanomaterial, that is, a carbon nanotube, the heat absorbing layer 14 has a relatively good absorption for sunlight and a near-infrared light band, and is converted into heat energy, and then passes through the set. The hot lower substrate 12 transfers thermal energy to the circulating flow layer 24. Since the carbon nanotubes in the heat absorbing layer 14 have excellent characteristics of good stability and high thermal conductivity, the efficiency with which the heat absorbing layer 14 transfers thermal energy to the circulating fluid layer 24 can be improved. In addition, the heat absorbing layer 14 absorbs solar energy and the temperature rises, and the heat absorbing layer 14 as a heat source also radiates heat outward. The arrangement of the reflective layer 22 can reflect the portion of the thermal radiation back into the cavity, which can reduce the heat loss of the solar thermal collector 100, and further improve the working efficiency of the solar thermal collector 100. ❹ The solar collector has the following advantages: f 典 gastric female white red and another love point. First, because nano carbon & has good (four) heat, so the carbon nanotube composite layer is used as the heat absorbing layer The energy absorption efficiency of the solar energy collector of the solar energy collector can be hooked up. Third, since the carbon nanotube is used as the heat absorbing layer, the choice of the substrate material is not limited.
