This special flow channel structure effectively improves the thermal efficiency of the collector.
Description
One, technical field
The utility model relates to solar energy heat utilization field, refers in particular to a kind of new-type plate type solar air collector, can be widely used in fields such as building and heating, material and cloth drying.
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
The purpose that the utility model proposes is to provide the plate type solar air heat-collecting device that a kind of air flows evenly, heat exchange efficiency is high.This device takes up room little, and external form rule, attractive in appearance is easy to and building combines, and can make full use of solar energy and for the user hot blast is provided.It mainly partly is made up of transparent cover plate, thermal-arrest plate, heat-insulation layer, framework, air duct and blower fan etc.Wherein thermal-arrest plate surface is coated with spectral selective absorbing coating, is drilled with densely covered aperture.Thermal-arrest backboard face connects a plurality of admission lines, and bottom of device connects outlet pipe, and blower fan links to each other with outlet pipe.The admission line of porous thermal-arrest backboard face is evenly distributed on a side of heat collector, and the outlet pipe that the heat collector bottom connects is distributed in the heat collector opposite side.Transparent cover plate and porous thermal-arrest plate are divided into two parts up and down with the heat collector cavity.
Four, description of drawings
Gather accompanying drawing below, the utility model is described further.
Fig. 1 is the structural representation of this device.
Fig. 2 is the A-A face cutaway view of this device.
The position of marking is respectively among the figure: 1, transparent cover plate; 2, blower fan; 3, outlet pipe; 4, admission line; 5, heat-insulation layer; 6, thermal-arrest plate; 7, sweating aperture.
Five, the specific embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described further.
Sunlight sees through transparent cover plate 1 and is radiated on the thermal-arrest plate 2, because the effect of spectral selective absorbing coating, thermal-arrest plate 6 becomes heat energy with conversion of solar energy, and produces high temperature.When the user need use hot blast; Start blower fan 2; Air flows into the cavity between transparent cover plate 1 and the thermal-arrest plate 6 equably through admission line 4, passes the densely covered sweating aperture 7 on the thermal-arrest plate 6 again, with thermal-arrest plate 6 abundant heat convections; Get into the cavity between thermal-arrest plate 6 and the bottom heat-insulation layer 5 at last, flow out from outlet pipe 3.Because air at first gets into the cavity above the thermal-arrest plate 2, from top to down passes the densely covered sweating aperture 7 on the thermal-arrest plate 2 then, so reduced the heat loss that heat convection caused between air and the transparent cover plate 1, has improved the thermal efficiency.
