Description
Technical field
The utility model belongs to Application of Solar Energy field, especially plate solar collector.
Background technology
Known plate solar collector arranges heat-absorbing plate core in insulation half box body, in plate core upper cover, glass cover-plate is formed, air layer is formed between glass cover-plate and plate core, the heat that plate wicking is received is passed to glass cover-plate by the mode of convection current by this air layer, heat is passed to glass surface by the mode of conduction by glass cover-plate, dissipate in an atmosphere, thus reduction collecting efficiency, for reducing this thermal loss, this sheaf space is filled dry air by technical staff, or inert gas, drier is deposited in space, blend compounds bar is by its peripheral sealing, such work, because dry air is lower than the heat transfer coefficient of humid air, think the heat insulation effect improving heat collector by this way, but, due to the difference variation that collector plate wicking surface is strong, time noon on daytime, sunshine was strong, the air of air layer is caused acutely to expand, pressure increase, go out sealing ring, when evening, temperature was low time, due to a part of having run away daytime in air layer, original air just adds that low temperature is but cool when few, volume-diminished, this space is made to form negative pressure, like this, extraneous air is just inhaled into this air layer, formed and breathe once a day, due to continuous respiration, make the drier of this air layer ineffective, the dry air of not water content is made to become humid air containing certain moisture content, humid air heat transfer coefficient is high, heat collector heat insulation effect is deteriorated, thus reduction collecting efficiency, further, this air also presss from both sides in some area has worn other harmful components, closing important coating for selective absorption, causing mortal injury, shortening the service life of solar thermal collector to causing.
Summary of the invention
Object of the present invention to provide a kind of plate solar collector, and the dry air layer above this plate solar collector heat-absorbing plate core can keep dry for a long time.
The technical scheme realizing above-mentioned purpose is: plate solar collector comprises frame, glass cover-plate, absorber plate, heat-insulation layer, base plate, fixed space and variable spaces; Wherein: frame and base plate and heat-insulation layer form insulation half box body, be incubated in half box body and place absorber plate, absorber plate upper cover glass cover-plate, gas heat insulating layer is formed between cover glass cover plate and absorber plate, between base plate and heat-insulation layer, fixed space is set, fixed space communicates with air, arranges variable spaces in fixed space, and variable spaces communicates with gas heat insulating layer through conduit.
Further, described variable spaces rubber makes, and has elasticity.
Further, described fixed space is tubular, and the variable spaces of the inside adapts therewith.
Further, the outer surface of described fixed space all applies reflective space adiabatic heat-insulation coating.
Further, what fill inside described gas heat insulating layer is dry air, places drier in air layer.
Further, what fill inside described gas heat insulating layer is inert gas.
Further, described fixed space is flat tube shape, and described variable spaces is strip hydrogen balloon, or threaded plastic bag.
Further, described fixed space is the true pipe syringe of glass.
Operation principle:
Because variable spaces rubber makes, it has good elasticity as hydrogen balloon, be arranged in a fixed space communicated with air, it can free to contract and expand, when noon the sun strong, the air of gas heat insulating layer is under the high-temperature baking of absorber plate, volumetric expansion, part dry air is just gone in variable spaces, when evening, temperature was low time, air layer cools, pressure reduces, variable spaces reduces, dry air in space gets back to again gas heat insulating layer, like this, utilize the variation effect of variable spaces, gas heat insulating stressor layer is made to remain steady, like this, just can avoid the respiration of gas heat insulating layer and airspace, enable the air that gas heat insulating layer keeps dry muchly.
Beneficial effect:
1., because of the air that gas heat insulating layer can keep dry for a long time, dry air conduction coefficient is low, makes heat collector can keep higher collecting efficiency muchly,
2. avoid moisture to enter, protect coating for selective absorption, extend the service life of heat collector.
3. time solar radiation is strong, the temperature of absorber plate is high, the dry air expanded by heating in gas heat insulating layer, run a part of in air bag, the dry air in gas heat insulating layer just becomes thinner, like this, the thermal conductivity factor of gas heat insulating layer is lower, is more conducive to improving collecting efficiency.
4. thin dry air heat-insulation and heat-preservation more, in the middle and lower reach of Yangtze River etc., the area that humidity is larger, the temperature of heat collector can improve about 10 degree, and the water heater be made with this heat collector will use more than 50 day every year.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram of plate solar collector.
Shown in figure: frame 1, glass cover-plate 2, absorber plate 3, heat-insulation layer 4, base plate 5, fixed space 6, variable spaces 7 gas heat insulating layer 8.
Detailed description of the invention
Below in conjunction with Fig. 1, detailed description of the invention of the present utility model is described,
This heat collector is made up of frame 1, glass cover-plate 2, absorber plate 3, heat-insulation layer 4, base plate 5, gasbag chamber 6, air bag 7 and gas heat insulating layer 8; Wherein: frame 1 forms insulation half box body with base plate 5 and heat-insulation layer 4, be incubated in half box body and place absorber plate 3, absorber plate 3 upper cover glass cover-plate 2, it is gas heat insulating layer 8 between cover glass cover plate 2 and absorber plate 3, between base plate 5 and heat-insulation layer 4, arrange fixed space 6, fixed space 6 has aperture to communicate with the external world, and variable spaces 7 is arranged on inside fixed space 6, variable spaces 7 connects a conduit, and this conduit communicates with gas heat insulating layer 8.Seal between conduit and fixed space 6, in gas heat insulating layer, fill dry air or inert gas.
Most preferred embodiment, fixed space 6 available metal or plastic production become flat tube, one end of flat tube is affixed on the base of frame, aperture is had to communicate with the external world, tubulose hydrogen balloon (or tubular plastic bag) is placed in flat tube, at oral area butting conduit of hydrogen balloon, described conduit communicates with gas heat insulating layer 8 through the closed end cap of flat tube and heat-insulation layer 4.To seal between described conduit and the closed end cap of flat tube.Because fixed space occupies certain position, heat-insulation layer herein decreases 1/3 or 1/2, for making up the deficiency of insulation layer thickness, just at the outer surface thermal insulation coat of flat tube, should preferably apply reflective space adiabatic heat-insulation coating.
Fixed space can make various shape with various material, and fixed space very causes a space of just heat-insulation layer bottom.This space, will communicate with the external world, airtight with heat-insulation layer.In this fixed space, arrange a variable spaces, described variable spaces is airtight, has polytype, and as cylinder and piston, syringe, glass needle tubing, the air bag of the various shapes that rubber or plastics are made, hydrogen balloon etc., all can be considered variable spaces.
Fixed space and variable spaces also can be made an annex, are arranged on the outside of flat plate collector.
As long as utilize variable spaces, adjust the pressure change of gas heat insulating layer, avoid respiration to reach, thus stop moisture to enter the gas heat insulating layer of flat plate collector, all belong to the protection domain of this patent.
