Description
Technical field
The utility model relates to solar facilities, particularly a kind of straight-through tab style solar energy heat collection pipe.
Background technology
Occurred a variety of solar energy heat collection pipes in existing market and patent, the solar energy heat collection pipe primary structure put goods on the market is: an end sealing, and the direct insertion structure of the double glazing that an end is uncovered, the advantage of above-mentioned direct insertion structure is that technique is simple, easy to process; Shortcoming is that to add thermal recovery microcirculation mode thermal-arrest limited in one's ability, is difficult for the water heated in pipe is all taken out, and can not meet the field use that larger bearing requirements is arranged.
The through type double-decker of open at both ends is disclosed in patent document, this structure has two types at present, a kind of is that inner tube is metal material, outer tube is glass material, be that ，Guan two ends, vacuum insulation space are metal connectors between pipe, carry out the sealing-in of glass and metal by kovar alloy, simultaneously on metal tube or glass outer tube, connect expansion joint, with compensation metal and the stress of generation different with linear expansion coefficient after the glass bi-material heats up.
The metal straight through heat collection tube is mainly used in high temperature photo-thermal power generation field, the report that abroad existing business is applied, but the domestic commercial application report that there is no.Its use cost is higher, is not suitable for test and industrialization and uses.Owing to using two kinds of different materials, can expand frequently, shrink with the variation thermal-collecting tube of temperature, the stress of generation checker, the tolerance degree difference of two kinds of counter stresses, the place's destructible that is tightly connected, make the lost of life.Another kind of type is all-glass construction, the glass round tube of identical material for inner and outer pipes, the glass inner tube of two kinds of structures and glass outer tube are glass round tube, it between two pipes, is vacuum chamber, the outer surface of glass inner tube scribbles solar selective coat, simultaneously the outer effective glass flange of glass is connected with bellows, in order to compensate the difference of the stroke that inner and outer pipes causes due to temperature difference.No matter all-glass construction is place along north-south or place along East and West direction, its effective collector area all can not surpass half of inner tube surface area, although increasing diameter of inner pipe, can improve corresponding collector area, but the increase of caliber, make that in pipe water-holding quantity is corresponding increases, and the temperature of final actual hot water is difficult for reaching higher water temperature, so above-mentioned glass straight through heat collection tube generally is applied to middle low-temperature water heating application, range of application is extremely restricted.
The utility model content
The utility model provide a kind of with low cost, collecting efficiency is high, the straight-through tab style solar energy heat collection pipe of long service life.
The utility model solves the technical scheme that its technical problem adopts:
Straight-through tab style solar energy heat collection pipe, comprise outer tube and inner tube, is provided with the straight-through inner tube of fin in described outer tube, be provided with bracing frame between the straight-through inner tube of outer tube and fin, the outer tube two ends are provided with glass cover, and the straight-through outer wall of inner tube of fin is provided with solar selective coat, and outer tube wall is provided with air exhaust nozzle.
The straight-through inner tube of described fin middle part projection, cross section is shuttle shape.
Support frame as described above comprises buckle and lower buckle, and upper and lower buckle is arranged along the outer tube vertical direction, and buckle is the X font, buckle one end and outer tube wall clamping, and the straight-through inner tube of the other end and fin fastens.
Be provided with many group bracing frames in described outer tube.
Described outer tube is provided with outer pipe expansion joint.
The material of the straight-through inner tube of described outer tube and fin is high-boron-silicon glass.
The utility model is shuttle shape by the Cross section Design of inner tube, the straight-through inner tube of fin middle part projection, and the heating surface area of increase inner tube, also can not make body deadweight and caliber significantly increase, and not only convenient the support installed, but also improved water temperature and thermal-collecting tube operating efficiency.Bracing frame comprises buckle and lower buckle, and upper and lower buckle is arranged along the outer tube vertical direction, and buckle is the X font, buckle one end and outer tube wall clamping, and the straight-through inner tube of the other end and fin fastens.Above-mentioned bracing frame can lead directly to inner tube by the firm grip fin, does not take space in pipe, can not block the straight-through inner tube of fin.Inner and outer pipe all adopts the glass of identical material to make, the tolerance degree of inner and outer pipe counter stress is identical, connection sealing can be more outstanding, set up outer pipe expansion joint on outer tube, in order to compensate the poor of stroke that inner and outer pipes causes due to temperature difference, further promote the cold-resistant heat resistance of outer tube, bulk life time significantly promotes.
