The selection of collector metal tube outer surface coating for selective absorption according to the invention: coating for selective absorption is an important step of solar thermal utilization, and it has material impact to the thermal conversion efficiency of system.If the optical property of coating is unstable, the hot property of whole system just can not get guaranteeing.Coating for selective absorption can be divided into 4 types of absorption/combinations of reflections rete, surperficial texture rete, resonance scattering rete and compound interference absorbing membranous layers, and wherein absorption/combinations of reflections rete and compound interference absorbing membranous layer are used the most common.Absorption/combinations of reflections rete generally designs by means of the absorption of semi-conducting material and the infrared external reflection of metallic substrate surface.It utilizes the electronic structure of semiconductor substance; Select natural or artificial synthetic semi-conducting material with suitable energy gap Eg; Absorb the solar radiation photon of energy greater than Eg; Thereby make the valence electron of material get into conduction band, and the photon of energy less than Eg seen through, thereby the infrared external reflection characteristic of surface of bottom material works.The compound interference absorbing membranous layer is that the light to a certain wavelength can produce destructive interference effect during by the deielectric-coating of non-absorption and absorbing composite membrane metal substrate or bottom film combination.This effect will absorb the solar energy of this wavelength when occurring in the peak wavelength of solar spectrum.Single inteferometer coating can only make that the reflectivity of a certain wavelength equals zero in the solar spectrum, absorb the solar energy of whole solar spectrum wave band, will design compound multilayer film.Practical coating for selective absorption should have following characteristic: 1. maximum absorptivity is arranged in the wave-length coverage of solar spectrum, the practicality coating is generally required α>=0.9; 2. when wavelength X＞2.5 μ m, high to the greatest extent reflectivity ρ is arranged, promptly in the serviceability temperature scope, its hemisphere emission is better more than more little, general operational requirement ε≤0.1.
Utilize outer membrane that the radiation less than critical wavelength is had higher absorbability, the radiation greater than critical wavelength is had good transmittance, black nickel-copper-stainless-steel base material film architecture is selected in the absorption of the highly reflective of underlying metal skin covering of the surface/combinations of reflections rete.From low-cost and technology easy; Selecting electroless copper for use is the high infrared reflection film; With the black nickel plating layer serves as that high thickness and the surface microscopic shape that absorbs outer coating has bigger influence to α and ε; So must on technology, control electroplating time, current density and bath temperature are so that the thickness and the surface quality of control rete.The optical property of black nickel plating coating is relevant with the fineness of the thickness of black nickel coating and substrate surface, and is relevant with coating process.The optical property of double-deck black nickel coating is superior to the optical property of the black nickel coating of individual layer, and double-deck black nickel coating can obtain through the way that increases current density by the time in proportion suddenly.The optimum thickness of double-deck black nickel coating is 0.048～0.063mg/cm
2, the optimum thickness of the black nickel coating of individual layer is 0.040～0.052mg/cm
2For effectively reducing the emissivity of black nickel coating, must improve the fineness of substrate surface.By thermal-collecting tube α>=0.94 that above technology makes, ε≤0.06.

A kind of heat collecting module of metal-glass sheathing heat collecting pipe operation principle of the present invention is the natural microcirculation method that changes former heat collector; But with forced circulation cold water through fill cycle runner batch (-type) (time is 30-300 second) through extending to the bottom that is injected into each collector metal pipe near the water injection pipe of collector metal pipe bottom respectively; Behind the solar irradiation, the coating of collector metal tube outer surface absorbs energy, heating water conservancy project matter; When the fluid temperature of experiencing connecting pipe outlet position when temperature sensor reaches a certain setting value; Circulating pump starts, and cold water re-injects the bottom of glass heat-collecting vacuum tube, simultaneously hot water is ejected.Water conservancy project matter does not contact with glass insulating layer, has avoided booster, the bursting by freezing of glass heat-insulating pipe.In case and the insulating tube fragmentation can not influence the operation of whole system yet.
Beneficial effect of the present invention is:
1, select the stainless steel tube elder generation electroless copper of thin-walled polishing to form infrared reflection film, the technology of plating again with black nickel is simple and feasible, i.e. energy-conserving and environment-protective have improved the light radiation absorption efficiency again widely.Traditional thermal-collecting tube is that the selectivity coatings absorbing light energy by inner tube outer surface passes to water conservancy project matter by glass again, because of glass is the poor conductor that conducts heat, so heat transfer efficiency is far below the heat transfer efficiency of stainless steel tube.Be sleeved on the outer transparent vacuum insulation glass tube of collector metal pipe and be more prone to make, because of having removed the magnetron sputtering plating link from, its cost significantly reduces.
2, the present invention has changed the problem of current disclosed heat collector water inlet of order and delivery port short-circuit flow, adopts cold water and go out hot water to be separated.
3, common all-glass solar vacuum tubular collector, phenomenon such as the Secondary Flow that produces because of free convection heat transfer, short-circuit flow, eddy current, turbulence causes that thermal starting is slow, the thermal efficiency is low, has also obtained solution because of the pressure thermal cycle among the present invention.
4, in the past all-glass solar vacuum tubular collector, because of the natural microcirculation of water conservancy project matter in the thermal-collecting tube, the thermal-collecting tube bottom is prone to deposition impurity wadding dirt, and the problem of easy to clean does not solve because of the straight-through thermal-collecting tube of water injection pipe of the present invention bottom yet.And can be because of forced circulation, the filter filtering of the system that flows through.
5, owing to special construction of the present invention, the water injection pipe near the thermal-collecting tube bottom through the circulation of drawing water of system, can blot the water conservancy project matter in the thermal-collecting tube very easily, and all-glass solar vacuum tubular collector can get into antifreeze or service mode.
6, adapt to the utilization that the special module structure of pressure-bearing (0.65MP-1.0MP) has solved skyscraper Nan Li face wall.
7, water conservancy project matter does not contact with glass insulating layer, has avoided booster, the bursting by freezing of glass heat-insulating pipe.In case and the insulating tube fragmentation can not influence the operation of whole system yet.
