Abstract
The utility model relates to a solar spectrum selective absorbing thin film, which comprises a copper substrate. A four-layer structure film system is used; three film layers are arranged on the copper substrate; and the four-layer structure film system comprises a copper substrate layer, a NiCrOxNy high metal content absorbing layer, a NiCrOxNy low metal content absorbing layer and a medium antireflection layer in sequence from the bottom to top. In the solar spectrum selective absorbing thin film, as three layers of nickel-chromium-oxygen-nitrogen composite thin films are prepared on the copper substrate by adopting a magnetron sputtering technology, the solar spectrum selective absorbing thin film has high absorption rate, low emissivity, good adhesion force and multicolor, and the solar spectrum selective absorbing thin film is applicable to a solar photo-thermal converter.
Description
Technical field
The utility model relates to a kind of selective solar spectrum absorbing membrane, particularly a kind of colored solar spectrum absorbing membrane, be to prepare solar spectral selective with magnetron sputtering technology to absorb composite film material, in order to realize the conversion of high-efficiency solar photo-thermal and to reach building decorative effect.
Background technology
The most direct valid approach of solar energy utilization converts solar energy to heat energy exactly and is used, and the height of solar thermal collector efficient is mainly determined by two factors, and the one, heat collector is to the absorbability of solar radiation; The 2nd, the radiation loss degree of heat collector.The total principle that improves its efficient be to absorb as much as possible solar radiant energy and try one's best reduce heat loss, have good absorbent properties and itself have only a small amount of thermal-radiating surface and the spectral selection absorbing membrane is exactly a shortwave radiation to the sun, thereby using the solar spectral selective absorbing membrane is one of the effective measures the most that improve collector efficiency.Realize best solar energy optical-thermal conversion, the thermal-arrest material that is adopted just must satisfy following two conditions: (being λ≤2.5 μ m) has the high absorptivity α that tries one's best in the solar spectrum scope; (being λ＞2.5 μ m) has alap radiation loss in heat radiation wavelength scope, and alap emissivity is promptly arranged.The coating material that possesses this characteristic is called as spectral selective absorbing coating.For solar thermal collector, obtain satisfied photo-thermal conversion efficiency, selective absorbing film is a necessary condition efficiently, is the sport technique segment of a key.Using solar water heater is an active and effective supplementary means that solves China's energy and environment problem at present.Whole nation solar energy heat absorbing material annual production in recent years is ten thousand square metres of 500-600, wherein 1/3rd be to use the plate type solar heat-absorbing plate core, demand to the selective solar spectrum absorbing membrane is big, plate water heater is easier organically to be combined with building, be good ascendant trend, have good market prospects.
Summary of the invention
The utility model provides a kind of selective solar spectrum absorbing membrane, it adopts magnetron sputtering technique to prepare three layers of composite membrane on copper base, form the four layer series structure, thereby the absorptivity height, the emissivity that reach film adhesion height, film are low, and the purpose of convertible film surface color.
Technical solution adopted in the utility model: a kind of selective solar spectrum absorbing membrane, comprise the copper base layer, adopt four-layer structure film system, it is characterized in that on the copper base layer, being provided with folded formula trilamellar membrane layer, be followed successively by copper base layer, the high tenor absorbed layer of NiCrOxNy, NiCrOxNy low-metal content absorbed layer and NiCrOx antireflection layer from bottom to up.
All contain Ni and Cr metallic particles in described high tenor absorbed layer and the low-metal content absorbed layer, the NiCrOx antireflection layer is the compound media coating.
Described copper sheet layer is the smooth copper sheet of surface-brightening.
The thickness of the high tenor absorbed layer of this film is 40～60nm, and the thickness of low-metal content absorbed layer is 40～70nm, and the thickness of antireflection layer is 40～70nm.
This structure deposits high tenor absorbed layer, low-metal content absorbed layer and antireflection layer successively on copper base, constitute three layers of composite membrane.
The beneficial effects of the utility model: this structure prepares trilamellar membrane with sputtering technology on copper base, constitute four-layer structure film system, tenor and the thickness regulated between each rete can reach good shortwave absorption and anti-reflective effect, bright simultaneously copper base has high infrared reflection and forms the infrared high reflection of whole selective absorption surface, thereby the whole film cording adhesive force that has high absorptivity, low emissivity to become reconciled, and by the nickel of interlayer, the variation of chromium metallic particles content, transfer the film surface color, to satisfy instructions for use.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1. copper base layer, 2. high tenor absorbed layer, 3. low-metal content absorbed layer 4. antireflection layers.
The specific embodiment
The contrast accompanying drawing specifies its structure.
In Fig. 1, adopt magnetron sputtering technique, the trilamellar membrane layer is set on bright copper substrate layer 1, be followed successively by copper base, the high tenor absorbed layer 2 of NiCrOxNy, NiCrOxNy low-metal content absorbed layer 3 and NiCrOx antireflection layer 4 from the bottom to top, copper base and the trilamellar membrane layer on it constitute total of the present utility model.This film is regulated the color of film by the variation of metallic nickel, chromium particle in the film, and for example turquoise, Zijin look, hyacinthine are to satisfy practical requirement.
