Abstract
A vacuum glass assembly with a collecting lens array is disclosed. The vacuum glass assembly has a double-layer glass structure; vacuum is built between the layers and the space between the layers is sealed; and the effects of supporting the vacuum and collecting solar light are achieved simultaneously by a method of arranging the collecting lens array on a side of one layer of glass which faces the middle interlayer. The collecting vacuum glass assembly has excellent thermal insulating/heat retaining properties and thereby can be applied to the solar light collecting optical-thermal field; and especially for the field of the high/medium-temperature flat plate collector, the application of the glass assembly means a breakthrough on heat collection temperature and optical-thermal conversion efficiency.
Description
Technical field
The utility model relates to a kind of vacuum glass assembly with condenser lens array.
Background technology
Solar energy has environmental protection as a kind of new forms of energy, and inexhaustible advantage is the focus that present various countries competitively research and develop.Yet because it is little to arrive tellurian solar energy energy-flux density, illumination is discontinuous; In order to utilize solar energy fully; Make things convenient for power conversion and improve conversion efficiency, the luminous energy density of managing to strengthen sunshine is the most effective one of means, and therefore various solar-energy light collectors arise at the historic moment.Except middle high temperature solar heat utilization must be adopted the optically focused means; In low-temperature solar energy solar thermal utilization field; Suitably carry out optically focused and adopt the excellent insulating measure can improve the solar energy thermal conversion efficiency greatly; Therefore under the situation of small-scale low-temperature solar energy solar thermal utilization (for example flat plate collector), optically focused and insulation are the key technology key elements.The vacuum glass assembly with condenser lens array that the present invention proposes is conceived to this two big technology essential factor just; Optically focused and heat insulation function are united two into one, and feasible photo-thermal conversion efficiency and the hot quality of using the solar energy heat utilization product of this vacuum glass assembly goes another step.For example use the light-focusing type flat plate collector of this vacuum glass assembly as transparent cover plate; Good at irradiation, optically focused is than suitable, under the condition of other insulation appropriate measures of plate core; Its inner heating-up temperature can reach more than 400 ℃, has widened the application and the region of flat plate collector.
Summary of the invention
To achieve these goals, the utility model provides a kind of vacuum glass assembly with condenser lens array.The characteristics of this vacuum glass assembly are: optically focused and heat insulation function united two into one, reduced the manufacture difficulty of vacuum glass assembly, and simple in structure, compact.
The utility model solves the technical scheme that its technical problem adopted: adopt double-layer glass structure; At glass surface anti-reflection film and selective reflection film are arranged; On a glass plate condenser lens array is arranged therein, and make condenser lens array between the layer glass plate, assemble, seal, vacuumize formation vacuum glass assembly again; Wherein, the negative pressure of the vacuum section in the middle of double glazing supports through condenser lens array.
The beneficial effect of the utility model is: can improve photo-thermal conversion efficiency and the hot quality of utilizing the solar energy heat utilization product that this vacuum glass assembly processes, and enlarge its range of application.Condensing evacuated glass assembly like this; Can and converge the light transmission to produce the higher heat energy of temperature; Can prevent that again heat radiation from can be good heat-insulation and heat-preservation assembly from the other direction passing glass assembly and scattering and disappearing, and can be used on the many aspects in the Salar light-gathering heat utilization field.
