Description

Infrared ray greenhouse type flat-plate solar collector

● technical field

Infrared ray greenhouse type flat-plate solar collector belongs to solar energy heat utilization technical field, relates to a kind of flat-plate solar collector.

● background technology

Vacuum tube solar heating element has good heat insulation, heat is imitated characteristics such as height, but load performance, installation capability, can not show a candle to flat plate collector with building binding ability attractive in appearance.The structure of classic flat-plate solar thermal collector is that fin thermal-arrest plate is housed on the thermal-arrest tube core, and be installed in the lump in the flat plate shape box-frame, towards sunny side euphotic cover plate is housed, this heat collector has that daylighting area is big, pressure-bearing, durable, simple in structure, advantage such as body is frivolous, and be convenient to and attractive in appearance combination of building, but heat-insulating property is relatively poor, and the thermal efficiency is on the low side.Patent application 02219193,00263979,00263980 has proposed several reduction euphotic cover plate heat-transfer capabilities respectively, has reduced the scheme of conductive heat loss, thereby improved collecting efficiency to a certain extent, but all there is following open defect in the flat plate collector of prior art: the one, the thermal-arrest plate be that the infrared energy major part of thermal-arrest plate directly or indirectly is lost to space outerpace to the transparent air window of infrared ray towards sunny side; The 2nd, the air in the casing certain fluctuation occurs with its pressure of variations in temperature of heat-collecting plate core, miscellaneous part to euphotic cover plate and heat collector produces mechanical function, influence the intensity of heat collector and the idealized selection of euphotic cover plate, the moisture that contains in the inner air of coming in extraneous respiration institute seepage of heat collector simultaneously, easily frosting is revealed and has been reduced light transmittance, influences collecting efficiency on euphotic cover plate.

● summary of the invention

The purpose of this utility model provides a kind of flat-plate solar collector that can control infrared radiation loss, form the heat-insulation layer of greenhouse effect and can improve stress, avoid the dewfall influence.

For achieving the above object, infrared ray greenhouse type flat-plate solar collector of the present utility model is made up of euphotic cover plate, thermal-arrest tube core, thermal-arrest plate, union pipe, solid heat-insulation layer, insulation box-frame and flexible balance film, printing opacity greenhouse gases and the infrared highly reflecting films of printing opacity; Towards sunny side euphotic cover plate being installed and forming plate shaped airtight casing of insulation box-frame, thermal-arrest tube core, solid heat-insulation layer, the flexible balance film of band thermal-arrest plate is housed successively from euphotic cover plate in casing, form preceding greenhouse, greenhouse, back and air balance chamber successively; Thermal-arrest plate and thermal-arrest tube core are fixedly connected into one and good heat conductive, adhere to solar energy absorbing membranous layer towards sunny side, and the solid heat-insulation layer is close at the back side, organize the thermal-arrest tube core more and are connected with the union pipe that has the medium import and export; The air balance chamber is communicated with atmosphere by the balance pipe on the box-frame, preceding greenhouse is communicated with the greenhouse, back by the gas port on solid heat-insulation layer and the thermal-arrest plate, the pure printing opacity greenhouse gases of filling in preceding greenhouse and the greenhouse, back, described printing opacity greenhouse gases are to visible transparent and to the gas of infrared ray absorbing; One side of euphotic cover plate is adhered to the infrared ray highly reflecting films of skim printing opacity.

The thermal-arrest plate can be made into and has corrugated surface or the corrugation face that favours dull and stereotyped basal plane; Euphotic cover plate also can adopt finished product hollow light-passing board, in the periphery sealing of the intermediate course of two-layer light-passing board, is evacuated in the interlayer or fills the printing opacity adiabatic gas; The printing opacity greenhouse gases are single greenhouse gases or more than one mixing greenhouse gases; Thermal-arrest tube core available metal siphunculus or phase transformation heat pipe can be installed antifreeze core and scale removal rod in the metal siphunculus.

After adopting said structure, when sunlight sees through euphotic cover plate and printing opacity greenhouse gases and shines solar energy absorbing membranous layer on the thermal-arrest plate, luminous energy is transformed into heat energy and is absorbed by the medium of thermal-collecting tube in-core, the infrared highly reflecting films reflection that the infrared radiation that the higher thermal-arrest plate of temperature is launched is formed on the euphotic cover plate, and by the greenhouse of the absorption of the printing opacity greenhouse gases in preceding greenhouse formation insulation effect; The printing opacity greenhouse gases expand with the rising of temperature, before making, thereby the gas pressure in the back greenhouse increase oppress flexible balance film to balance cylinder's direction distortion with the dilatation step-down, before the respiration of air in the balance cylinder by balance pipe makes, printing opacity greenhouse gases pressure in the back greenhouse and external atmospheric pressure keep balance, thereby guaranteed that euphotic cover plate and heat collector work and the poor effect that is not stressed under atmospheric pressure environment, pure greenhouse gases have been avoided frosting, the dewfall phenomenon, if select the heat-transfer capability greenhouse gases more less than air, heat insulation effect further improves; Inclination corrugated surface on the thermal-arrest plate or corrugation face can guarantee the favourable angle that heat collector tilts or vertical direction is installed back and sunlight; The hollow euphotic cover plate has higher thermal resistance, reduces the heat transfer loss, improves heat insulation effect.Heat collector of the present utility model and water tank can be formed hot-water heating system, cooperate with other equipment and can form solar airconditioning, solar energy production process system or the like; But the utility model independent inclination is installed, and also can be used as construction wall parts or decorative element and vertically inlays installation, and it is convenient and attractive in appearance to use.
