Description
Technical field
The utility model relates to a kind of straight-through vacuum tube solar air collector.
Background technology
Over more than 20 year, passive solar house has obtained applying to a certain degree in the rural area of northern China, has not only improved grange indoor thermal environment in winter situation, and has saved a large amount of heating coal consumptions.But because the current Te Longbu thermal-arrest body of wall that generally adopts is subjected to the not influence of factor such as easy-maintaining and construction quality, many its heating functions of having lost gradually.
The wall-hanging solar air collector has appearred in the solar heating The Application of Technology for the ease of existing building transformation and future city building.
Solar energy air heat collector is to use air as the solar thermal collector of heat transfer agent, and solar energy is converted to heat energy, provides the hot blast workpeople to use.Can provide the pollution-free green energy at aspects such as crops drying, constructure heatings at present.For example be incubated the dehumidifying that heats up of good hypogee, perhaps be difficult to dryly as in the used for drying corps operations such as red date, solar energy air heat collector obtains using more widely.
At present vacuum pipe solar air collector on the market all adopts inner-intubation, and vacuum tube adopts the vacuum tube of end opening other end sealing, and air enters from interpolation pipe and flows to the vacuum tube bottom and be back to header then.Can make the diameter of runner reduce half at vacuum tube interpolation mozzle, runner prolongs one times, and on-way resistance just increases 2 times like this; Because under the certain situation of flow, caliber dwindles the back flow velocity and increases, and on-way resistance also can increase.Cause blower fan power consumption bigger like this, cause energy waste.
Another kind of main flow solar energy air heat collector is bilateral tube solar air collector, and the inner-diameter portion whose of its bilateral pipe causes collector efficiency to descend because do not have shelter, air to be easy to form laminar flow.
Summary of the invention
Therefore, the purpose of this utility model is, a kind of straight-through vacuum tube solar air collector is provided, and improves the solar collecting performance of heat collector by the mode of flow-disturbing.
The technical solution adopted in the utility model is:
A kind of straight-through vacuum tube solar air collector comprises one group of straight-through vacuum pipe and the heat collector assembly of this group straight-through vacuum pipe connection collection, the interior tubular axis of described straight-through vacuum pipe is to being provided with flow spoiler.
From said structure as can be seen, according to the utility model, adopt the straight-through vacuum pipe, and pipe arranges flow spoiler within it, thereby it is disorderly that institute's ventilating air is produced, and is not easy to produce air stratification, thereby guaranteed collecting efficiency.And said structure is relatively simple, and low cost of manufacture is convenient to safeguard.
In certain embodiments, above-mentioned straight-through vacuum tube solar air collector, described flow spoiler are the helical member of pipe internal surface in being supported in.
Above-mentioned straight-through vacuum tube solar air collector, the lead angle of described helical member is 70 ~ 85 °.
In further embodiments, described flow spoiler is to the array of fins of extending at interior caliber.
Further, the length of described fin is 0.15 ~ 0.2 times of interior pipe radius.
In some embodiment again, above-mentioned straight-through vacuum tube solar air collector, described flow spoiler are from the uniform thorn that entad extends of interior pipe internal surface.
Above-mentioned straight-through vacuum tube solar air collector also comprises the connection collection parts for the described straight-through vacuum pipe of connection collection, and should connection to collect parts be the header that is built-in with union pipe, and this header is furnished with heat-insulation layer.
Description of drawings
Fig. 1 is according to a kind of straight-through vacuum tube solar air collector structural representation of the present utility model.
Among the figure: 1, cold air inlet, 2, the cold wind header, 3, heat-insulation layer, 4, straight-through vacuum pipe, 5, the hot blast header, 6, hot-blast outlet, 7 flow spoilers.
The specific embodiment
With reference to a kind of straight-through vacuum tube solar air collector shown in the explanation accompanying drawing 1, adopt one group of straight-through vacuum pipe 4, two ends join collection by union pipe respectively, form the collector structure with irradiation face as shown in Figure 1, two corresponding union pipes, one flows into cold wind, another outflow is heated the hot blast that the back forms, as shown in Figure 1, to cold air inlet 1 and hot-blast outlet should be arranged, those skilled in the art should have clearly understanding to this.
Straight-through vacuum pipe 4 full name are straight-through type solar energy vacuum heat collecting tubes, comprise inner glass tube (pipe in being called for short, the pipe metal tubes that adopt in middle temperature is above) more and are sleeved on cover glass tube on the inner glass tube, and sealing-in formation vacuum chamber vacuumizes and namely forms vacuum tube between pipe.
Air to be heated is passed to the other end from an end of interior pipe, when not by disturbance, circulation of air is more stable, owing to expand with heat and contract with cold, can be easy to generate laminar flow, hot part is easier being heated in the above, needs heated air to be difficult to obtain heat below, because the influence on warm rank causes collecting efficiency lower.
For inferior, as shown in Figure 1, the interior tubular axis of described straight-through vacuum pipe 4 is to being provided with flow spoiler 7.After adopting straight pipe, under the certain situation of flow, speed air flow reduces, and pipeline pressure falls and reduces; It is big that diameter becomes, and pipeline pressure falls and reduces, and can lower the power of blower fan so to a great extent, makes whole system more energy-conservation.After increasing disturbing flow device, air is flowed produce disorder, heat exchange is more even, and collector efficiency is provided.
Flow spoiler 7 can make rule or irregular shape put with the straight-through vacuum pipe in, in certain embodiments, described flow spoiler 7 is the helical member of pipe internal surface in being supported in.Helical member is made simple, is similar at interior pipe and forms internal thread, is subjected to the influence of boundary current, and institute's ventilating air is converted into eddy current at leisure, thereby can avoid occurring laminar flow effectively.
Find that through experiment when the lead angle of described helical member was 80 ° of left and right sides, Heat-collecting effect was higher, was subjected to flow rate effect simultaneously, the best set thermal effect may not be exactly 80 °, through long-term checking, under 70 ~ 85 ° of conditions, collecting efficiency difference is less, exceeds this scope, and the collecting efficiency fluctuation becomes big.
In certain embodiments, described flow spoiler is that fin can be arranged according to the fork in the fluidics in the array of fins of interior caliber to extension, to improve the flow-disturbing effect.
Fin is unsuitable long, otherwise can increase flow resistance, for balance flow-disturbing and flow resistance, and when finding that through checking the length of described fin is 0.15 ~ 0.2 times of interior pipe radius, better both pros and cons of balance.
In some embodiment again, described flow spoiler is from the uniform thorn that entad extends of interior pipe internal surface, and it is poor slightly to stream effect, and cost is relatively low.
As shown in Figure 1, the connection collection parts that are used for the described straight-through vacuum pipe of connection collection are the header that is built-in with union pipe, and this header is furnished with heat-insulation layer 3, to reduce heat waste.
