Description
Technical field
The utility model relates to a kind of vacuum pipe solar air collector, belongs to solar energy utilization technique field.
Background technology
The energy is the basis of human survival and development of relying, but current many national ubiquity energy crises.Conventional fossil fuel has negative effect to environment, and therefore countries in the world man is all greatly developing regenerative resource.Solar energy is one of potential regenerative resource of current most.Solar energy air heat collector is one of Technical comparing maturation in solar thermal utilization, has a wide range of applications in the field such as industrially drying, solar heated green house.Current known vacuum tube air collector is a kind of is the simple straight through heat collecting device of structure formed primarily of header and all-glass vacuum tube, but the hot-air in its vacuum tube and the mobility between the cold air in collector not strong, there is the large temperature rise of air mass flow little, or the little temperature rise of air mass flow is large, the problems such as overall efficiency is low.Another kind of heat collector is transformed collector inside, application mozzle, strengthen the thermal convection current between collector and vacuum tube, but structure is too complicated, high to technological requirement, cost is too high, and internal drag causes greatly, and air mass flow is little need could improve flow with air blast, efficiency improves not obvious, and practicality is not high.
Summary of the invention
The purpose of this utility model is to overcome the existing technical deficiency of existing solar energy vacuum tube air collector, provides the vacuum pipe solar air collector that a kind of dependable performance, overall efficiency are high, economical and practical.
The utility model is achieved through the following technical solutions: a kind of vacuum pipe solar air collector, comprise a vacuum tube collector, several all-glass vacuum thermal-collecting tubes, air inlet and outlet lay respectively at the two ends of vacuum tube collector, it is characterized in that: be provided with air conducting sheet, air conducting sheet forms by two sections, first paragraph flow deflector is positioned at vacuum tube collector, and be provided with a draw-in groove, second segment flow deflector is positioned at all-glass vacuum thermal-collecting tube, be divided into two by vacuum tube, the connection realizing two sections is inserted in the draw-in groove of first paragraph flow deflector in its front end; First paragraph flow deflector is towards air intlet lateral buckling.Like this, after cold air flows into vacuum tube collector from air intlet, due to the barrier effect of air conducting sheet, air flows out vacuum tube along flow deflector again by behind the bottom entering vacuum tube along flow deflector.After so flowing through each vacuum heat collection pipe successively, then flow out through the air outlet slit of collector.Like this, air can both realize forced-convection heat transfer in each vacuum tube, improves heat transfer efficiency, thus improves the thermal efficiency of system.And can the degree of depth of draw-in groove be inserted by changing second segment flow deflector thus change its length in vacuum tube inside, thus reach the size regulating heat collector inner air flow resistance to a certain extent, and then control temperature rise and the flow of outlet air.The quantity of vacuum tube can according to required air temperature, Flow-rate adjustment.
Compared with prior art, tool has the following advantages the utility model:
1, under the effect of air conducting sheet, air can be heated repeatedly, obtain high temperature air, and heat utilization efficiency is high.
2, the utility model internal structure is simple, and resistance is little still can obtain good temperature rise under large discharge, can obtain good flow value when Natural Circulation.
3, first paragraph flow deflector is connected by draw-in groove with second segment flow deflector, easy installation and removal, and flow deflector quality is light, the little not fragile vacuum tube of volume, and the length of second segment flow deflector can be regulated to control air collector internal flow resistance.
4, the utility model stable performance, easy for installation, collecting efficiency is high, and economic and practical is high.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is vacuum tube and flow deflector schematic diagram.
Fig. 3 is that first paragraph flow deflector is connected front view with second segment flow deflector

In figure, 1. vacuum tube collector, 2. all-glass vacuum tube, 3. first paragraph flow deflector, 4. second segment flow deflector, 5. air intake, 6. primary air runner, 7. air outlet slit, 8. vacuum light connector, 9. collector heat-insulation layer, 10 flow deflector draw-in grooves.
detailed description of the invention:
A kind of vacuum pipe solar air collector, comprise a vacuum tube collector (1), all-glass vacuum thermal-collecting tube (2), air conducting sheet is made up of first paragraph flow deflector (3) and second segment flow deflector (4).Vacuum tube collector is provided with air intake (5), primary air runner (6), air outlet slit (7), vacuum tube connector (8) heat-insulation layer (9) is housed.A kind of vacuum pipe solar air collector is characterized in that being provided with first paragraph flow deflector (4) in primary air runner inside, and first paragraph flow deflector is connected by draw-in groove (10) with second segment flow deflector.Vacuum tube to be connected with vacuum tube collector by vacuum tube connector and to communicate with primary air runner, and vacuum tube inner space is divided into two-layer by air conducting sheet.The quantity of vacuum tube can according to required air temperature, Flow-rate adjustment.
Embodiment 1
A kind of vacuum pipe solar air collector mode of operation: under the effect of air blast, cold air enters primary air runner (6) from air intake (5), first paragraph flow deflector (3) and second segment flow deflector (4) guide functions next directly enter into vacuum tube (2) end, after get back to primary air runner (6) along air conducting sheet again, and fully absorb the heat of vacuum tube (2) in the process.Vacuum tube (2) is again entered again under the effect of pressure effect and first paragraph flow deflector (3) and second segment flow deflector (4), class this repeated multiple times after obtain middle high temperature air, finally derive from air outlet slit (7), avoid the shortcoming of the deficiency of heat collector temperature rise now.
