Abstract
The utility model discloses a heat absorbing fin plate of an intermediate-temperate solar flat plate collector, which includes a metal bottom plate. The utility model has a key point that a layer of TiAlN infrared reflection resistant film, two layers of TiAlON composite absorbing films and a layer of TiAlO radiation resistant composite protection film are sequentially arranged on the metal bottom plate. The utility model has benefits that because TiAlN has the infrared reflectivity close to that of gold and has lower low-temperature emissivity and heat loss, the thermal insulation performance is better; and at the same time, TiAlN is an excellent, wear-resistant and oxidation-resistant material with high hardness, so that the flat plate collector using the coating has excellent weather resistance and oxidation resistance, and the use performance at an intermediate-temperate about 150 DEG C can be excellent. The utility model solves the technical problems that the prior art is not ideal in resistance to infrared reflection and resistance to thermal radiation.
Description
Technical field the utility model belongs to the solar energy optical-thermal applied technical field, relates to a kind of flat plate collector absorber plate, specifically a kind of middle temperature solar flat plate collector heat absorption fin plate.
The flat plate collector heat absorption fin plate of background technology prior art comprises metal base plate, and metal base plate is provided with one deck reflectance coating, and Coating Materials is TiNxOy or NiCr.The flat plate collector heat absorption fin plate of this structure is in producing and using, the deficiency that exists is, the performance of antagonism far-infrared reflection and heat resistanceheat resistant radiation is all not really desirable, just all do not reach best effects to the absorption of sunlight with to the heat preservation effect, about 150 ℃ of temperature are when using particularly, and it is in addition perfect to also have many problems to await in the industry scientific and technical personnel.
The summary of the invention the purpose of this utility model is to solve the undesirable technical problem of performance that prior art exists antagonism far-infrared reflection and heat resistanceheat resistant radiation, purpose be to solve the undesirable technical problem of performance that prior art exists antagonism far-infrared reflection and heat resistanceheat resistant radiation, a kind of middle temperature solar flat plate collector heat absorption fin plate is provided, thereby overcomes the deficiencies in the prior art.
For achieving the above object; temperature solar flat plate collector heat absorption fin plate in the utility model; comprise metal base plate, its main points are to be provided with one deck TiAlN counter infrared ray reflectance coating, two-layer aluminum oxynitride titanium composite absorption film and one deck aluminium oxide titanium radioresistance composite protection film on metal base plate successively.
The invention has the beneficial effects as follows, because the infrared reflectivity of TiAlN (TiAlN) and infrared reflectivity and gold are approaching, have lower low temperature emissivity and heat waste, heat-insulating property is better, TiAlN is a kind of high rigidity of high-quality, wear-resisting and oxidation-resistant material simultaneously, therefore use the flat plate collector of this coating to have good weatherability and oxidative resistance, can be about 150 ℃ in warm serviceability good.The utility model has solved prior art and has had the undesirable technical problem of performance of resisting far-infrared reflection and heat resistanceheat resistant radiation.
Appended drawings is the utility model structural representation.
Among the figure 1, counter infrared ray reflectance coating 2, the first composite absorption film 3, the second composite absorption film 4, radioresistance composite protection film 5, metal base plate
The specific embodiment is with reference to accompanying drawing; temperature solar flat plate collector heat absorption fin plate in the utility model; comprise metal base plate 5, on metal base plate 5, be provided with one deck TiAlN counter infrared ray reflectance coating 1, two-layer aluminum oxynitride titanium composite absorption film 2,3 and one deck aluminium oxide titanium radioresistance composite protection film 4 successively.
When the utility model prepares at rete, workpiece metal base plate 5 is contained on the pivoted frame of two target magnetic control sputtering coating machines, rotation in the time of the workpiece revolution, the operation of automatic program control sputter coating process, technology has been moved the back and has been taken out workpiece.
Operating procedure is as follows:
The preparation method of rete belongs to the reactive magnetron sputtering method, and sputter gas is an argon gas, and reacting gas is high purity oxygen gas and nitrogen, and rete is divided into four layers of sputter, and some transition zones are arranged therebetween.

Operating pressure 0.2-0.5Pa, reacting gas nitrogen amount 20-200Sccm, sputter thickness 0.04-0.3 μ m;
2, the first composite absorption film 2, aluminium oxynitride titanium TiAlNO sputter, titanium al proportion 1: 1, operating pressure 0.2-0.8Pa, reacting gas nitrogen, nitrogen oxygen ratio 0.2: 1, gas flow 60-150Sccm, sputter thickness 0.04-0.1 μ m;
3, the second composite absorption film 3, aluminum oxynitride titanium TiAlNO sputter, titanium al proportion 1: 1, operating pressure 0.2-0.8Pa, reacting gas nitrogen, nitrogen oxygen ratio 0.2: 1, gas flow 60-150Sccm, sputter thickness 0.04-0.15 μ m;
4, the radioresistance composite protection film 4, aluminium oxide titanium TiAlO sputter, 1: 1 operating pressure 0.2-0.8Pa of titanium al proportion, reacting gas amount of oxygen 30-200Sccm, sputter thickness 0.03-0.12 μ m.
Rete is pressed the sputter material branch, and film structure is divided into four layers of sputter and forms, and the thickness of each layer sputtered film is to be finished by twice above sputter at least by the material of identical material, final formation: metal/TiAlN/TiAlON/TiAlON/TiAlO composite film coating thermal-arrest plate.
