Description
Technical field
The present invention relates to solar energy heating technical field, especially a kind of evacuated collector tube for being used to gather solar energy.
Background technology
The existing evacuated collector tube for being used to gather solar energy generally comprises circular glass thermal-collecting tube, the pipe of the thermal-collecting tube
Wall has the vacuum glass double-layer tube wall of spectrum selective paint, thermal-collecting tube one end open in, and coating can be selectively absorbed
Solar spectrum, absorbs solar radiant energy to greatest extent.Through sunlight, photon strikes coating, solar energy changes into thermal energy, water
To absorb heat outside coating, water temperature rise, density reduces, and hot water moves upwards, and heavy cold water declines, thus in thermal-collecting tube
Top water temperature is higher, and lower part water temperature is relatively low, and sunlit scope more exacerbates upper water warm again more on top,
The relatively low phenomenon of lower part water temperature, causes the water temperature heating in pipe uneven, and the low shipwreck of temperature of lower is made with effectively being heated
Whole thermal-collecting tube drops bottom to the efficiency of heating surface of water；And the thermal-collecting tube of one end open cannot direct water pipe, allow water directly through.
The content of the invention
Problem to be solved by this invention is to provide a kind of vane type solar energy heat collection pipe, to solve existing solar energy collection
The problem of heat pipes heat is uneven, and the efficiency of heating surface is not high.
To solve the above-mentioned problems, the technical scheme is that：This vane type solar energy heat collection pipe includes circular glass
Thermal-collecting tube, the tube wall of the thermal-collecting tube have the vacuum sealing tube wall of the double glazing of spectrum selective paint, the thermal-arrest in
Pipe both ends open, the thermal-arrest inner axial tube are equipped with multiple revolving parts successively, and each revolving part includes one and the collection
Round bar made of the transparent resin that heat pipe is axially set, the round bar are radially radioactively evenly arranged with multi-disc transparent resin
Blade, the blade are reduced from itself and the round bar junction to its afterbody arc；The diameter of the round bar is less than the thermal-arrest
2 the percent of bore, the maximum gauge of the blade are less than 1/5th of the rod diameter；When in the thermal-collecting tube
When water is produced flowing by heating, revolving part described in water flowing generation pressure-driven slightly rotates；When the both ends of the thermal-collecting tube have
Water flow pressure is poor, when each blade of the revolving part is pressurized inconsistent, the revolving part rotation.
In above-mentioned technical proposal, more specifically scheme can be：The blade is integrally formed with the round bar；The leaf
The distance between piece afterbody and the collector tube inner wall are in the range of the thermal-arrest bore 6 percent to 10.
Further：The blade has six.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
This vane type solar energy heat collection pipe is the vacuum sealing tube wall of double glazing, and thermal-collecting tube both ends open, both ends can be direct
Water receiving pipe；Using the revolving part with blade, during using being produced flowing by heating in thermal-collecting tube, water flowing is produced described in pressure-driven
Revolving part slightly rotates so that in thermal-collecting tube water along thermal-collecting tube Radial Flow,；When there is water flow pressure at the both ends of the thermal-collecting tube
Difference, when each blade of the revolving part is pressurized inconsistent, the revolving part rotation, automatically balances thermally equivalent, reaches
To being heated evenly, the high effect of the efficiency of heating surface；The arc of blade is excessive, is adapted to water jet propulsion blade；Transparent resin is material, then
Plus the requirement of the size of blade and round bar, neither influence to be heated, but it is lighter, and rotational resistance is small；Blade and round bar one into
Type, not only simplifies structure, but also the obstruction of current will can be preferably minimized.
Brief description of the drawings
Fig. 1 is the front view of the embodiment of the present invention；
Fig. 2 is the left view of the embodiment of the present invention.
Embodiment
The embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings：
This vane type solar energy heat collection pipe as shown in Figure 1 and Figure 2, it includes circular glass thermal-collecting tube, and the tube wall of thermal-collecting tube is interior
There is the vacuum sealing tube wall of the double glazing of spectrum selective paint 2, outer tube wall 1 and the sealing of inner tubal wall 3 form vacuum tube wall, collect
Heat pipe both ends open, both ends can direct water receiving pipes；Thermal-arrest inner axial tube is equipped with multiple revolving parts successively, and each revolving part includes
Round bar 4 made of a piece transparent resin axially set with thermal-collecting tube, round bar 4 are radially radioactively evenly arranged with six thoroughly
Ming tree fat blade 5, blade 5 are reduced from itself and 4 junction of round bar to its afterbody arc；When water is produced flowing by heating in thermal-collecting tube
When, water flowing produces pressure-driven revolving part and slightly rotates；When the both ends of thermal-collecting tube have, water flow pressure is poor, each leaf of revolving part
When piece is pressurized inconsistent, revolving part rotation.During using being produced flowing by heating in thermal-collecting tube, water flowing is produced described in pressure-driven
Revolving part slightly rotates, so that water automatically balances thermally equivalent, reach heated equal along thermal-collecting tube Radial Flow in thermal-collecting tube
It is even, the high effect of the efficiency of heating surface；The arc of blade is excessive, is adapted to water jet propulsion blade 5；Blade 5 is integrally formed with round bar 4, both
Simplify structure, and the obstruction of current will can be preferably minimized；The diameter b of round bar 4 is less than 2 the percent of thermal-arrest bore a,
The maximum gauge c of blade 4 is less than 1/5th of 4 diameter b of round bar；When water is produced flowing by heating in thermal-collecting tube, water flowing
Pressure-driven revolving part is produced slightly to rotate.The distance between 5 afterbody of blade and collector tube inner wall d are in thermal-arrest bore a percentages
Six to 10 in the range of, specifically, the distance between 5 afterbody of blade and collector tube inner wall d are thermal-arrest bore a hundred
/ six.Transparent resin is material, along with the requirement of the size of blade and round bar, neither influences heated and lighter, rotation
Resistance is small.
