Abstract
The invention discloses a solar air heat collector with a corrugated plate. A heat absorbing plate of the solar heat collector is a wavy thin metal plate, a plurality of small circular holes which are uniformly distributed are disposed on the wavy thin metal plate, the section of the heat absorbing plate is a wavy thin plate, fluctuation of crests and troughs of the heat absorbing plate is smooth, and the small circular holes which are densely arranged are distributed on the heat absorbing plate. The heat absorbing plate is wavy, accordingly, mechanical strength of the heat absorbing plate can be improved, and pressure resistance and deformation stress resistance are enhanced. Simultaneously, larger heat absorption area for sunlight irradiation on the heat absorbing plate is increased due to the wavy fluctuation, a better heat absorbing angle is realized, multiple reflection and absorption are generated, heat transfer efficiency between the heat absorbing plate and air can also be strengthened, and accordingly a heat performance of the air heat collector is enhanced.
Description
One, technical field
The present invention relates to solar energy heat utilization field, refering in particular to a kind of absorber plate is the solar energy air heat collector that has the waveform metallic plate of a plurality of even densely distributed prototype apertures.
Two, background technology
The plate type solar air collector is a kind of solar energy heat collector that utilizes air for medium, is highly suitable for fields such as heating in solar energy building, dehumidifying, industrial or agricultural dry materials.Compare with the vacuum tube type solar energy heat collector, advantage such as that the plate type solar air collector has is simple in structure, the sunlight footprint is big, seal request is low, it is antifreeze not need, cleaning, response are fast, but also have shortcomings such as heat loss is big, collecting efficiency is low.How further to improve the collecting efficiency of plate type solar air collector, be the target that the scientific research personnel pursues always.
The plate type solar air collector mainly is made up of transparent cover plate, absorber plate, insulation shell three parts.During work, the absorber plate that scribbles coating for selective absorption is converted into heat energy with solar radiation, and heat is passed to flow air through heat conduction and convection current.Because air tends to away shortest path from import to outlet (being usually located at the two ends of absorber plate clinodiagonal), and the buoyancy convection current can take place after being heated in air, so air-flow is difficult to evenly flow through absorber plate top each point.Therefore, the plate type solar air collector since air-flow easily " short circuit " cause heating uneven, make the air can not be efficiently and the absorber plate heat exchange, become the principal element that influences its collecting efficiency.
To the problems referred to above of plate type solar air collector, existing some kinds of corrective measures.For example: patent " a kind of binary channels waveform central layer solar energy air heat collector " (patent publication No. CN200986333); The above and below that it is characterized in that absorber plate is separated into two heat tunnels with heat collector cavity; Increased the path that air heats in heat collector, adopted the wave mode heat collection chip to increase collector area simultaneously and strengthen the disturbance of air.Patent " tortuous flow doubleeffect heating solar heat-collector air heat collectors " (patent publication No. CN101178260A); Between absorber plate and insulation base plate, adopt the airtight hot-flow flue that adds; Adding the thermal-collecting tube that vacuum heat-preserving is set again above the hot-flow flue; Make gas do secondary cycle between hot-flow flue and the vacuum heat collection pipe and flow adding, so that obtain better heat exchange.
The enforcement of above-mentioned patent all has certain effect to the thermal efficiency that improves solar energy air heat collector, plunders the formula heat convection but still belong to traditional plate between air and the absorber plate, and the increase rate of the thermal efficiency is less.
Three, summary of the invention
A kind of corrugated sheet solar energy air heat collector that the present invention proposes, this heat collector is made up of air inlet, absorber plate, air outlet, insulation shell and transparent cover plate, and wherein absorber plate is a waveform metal sheet that has a plurality of equally distributed circular apertures.The absorber plate cross section is the thin plate that waveform rises and falls, and crest and trough fluctuation ratio are milder, and are distributed with the circular aperture of dense arrangement.An absorber plate side on the sunny side is coated with selective heat absorbing coating.Four limits and the insulation shell of absorber plate are combined closely, air cavity and back air cavity before the spatial that insulation shell and transparent cover plate are surrounded is slit into.Under fan action, air cavity before air gets into from air inlet gets into the back air cavity after passing the aperture on the absorber plate, and flows out from air outlet.Absorber plate is shaped as waveform, can increase its mechanical strength, makes compressive resistance and anti deformational force strengthen.Simultaneously waveform rises and falls has more endotherm area when making solar radiation on absorber plate, the angle of better absorbing heat, and produces repeatedly reflection and absorb, and the heat transfer efficiency of absorber plate and air also can be enhanced, thus the hot property of raising air collector.

The position of marking is respectively among the figure: 1, air inlet; 2, preceding air cavity; 3, absorber plate; 4, back air cavity; 5, air outlet; 6, insulation shell; 7, transparent cover plate; 8, circular aperture.
Five, the specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described further.
The external blower fan of the present invention.Sunlight sees through transparent cover plate 7 and is radiated on the absorber plate 3, because the effect of spectral selective absorbing coating, absorber plate 3 becomes heat energy with conversion of solar energy, and produces high temperature.When the user need use hot blast, start blower fan, air cavity 2 before air flows into through air inlet 1 equably passes the rectangle aperture 8 that evenly gathers on the absorber plate 3 again, with absorber plate 3 abundant heat exchange, gets into back air cavity 4 at last, flows out from air outlet 5.Because air cavity 2 before air at first gets into, from top to down passes the rectangle aperture 8 that gathers on the absorber plate 3 then, so reduced the heat loss that heat convection caused between air and the transparent cover plate 7, has improved the thermal efficiency.The absorber plate of waveform can repeatedly reflect sunlight in addition, improves absorptivity, and the waveform absorber plate can increase and accepts illuminating area.
