Abstract
The utility model relates to a bi-pass glass-metal vacuum solar heat collecting pipe with a direct compensation inner pipe, which relates to the structural design of the bi-pass glass-metal vacuum solar heat collecting pipe. The utility model is mainly composed of a glass outer pipe, a metal inner pipe of which the surface is plated with a selective absorbing coating layer, an exhaust pipe, an outer through pipe which is connected with both ends of the metal inner pipe, and metal caps which are in sealing connection with both ends of the metal inner pipe and the glass outer pipe, wherein, a vacuum sandwich layer is arranged between the metal inner pipe and the glass outer pipe, and the metal inner pipe uses completely or partially a corrugated metal pipe. Because the metal inner pipe is directly manufactured into the corrugated pipe, one end of the metal inner pipe is not needed to be in sealing connection with a length compensator (the corrugated pipe), so the inner pipe is simple in structure, moreover, the welded seams are reduced, the leakage probability is reduced, the rate of finished products is increased, and the anti-pressure ability of the entire pipe is raised; the inner pipe and the corrugated pipe are combined into one, which simplifies the technology and reduces the cost; the corrugated pipes of different lengths can be manufactured on the inner pipe according to the working conditions of the entire pipe so as to widen the application range of the solar heat collecting pipe.
Description
Skill wood field
The utility model relates to a kind of vacuum solar collector tubes, the structural design of particularly a kind of bilateral glass-metal vacuum solar thermal-collecting tube.
Background technology
Glass-metal vacuum solar thermal-collecting tube is made up of transparent glass outer tube and the metal inner pipe that is coated with coating for selective absorption, be tightly connected with outer siphunculus respectively again behind the two ends of inner and outer pipe and the metal cap sealing by fusing, constitute the thermal-collecting tube of bilateral type, the interlayer between the inner and outer pipes is evacuated.
What the patent No. 99107429 related to is a kind of spiral full glass bilateral vacuum solar collector tubes of glass that has the solar spectrum absorber coatings.The applicant attempts in the version adjustment with helix tube pipe because of the cold and hot length variations that causes, but because glass is a kind of fragile material that does not have strain, does not reach above-mentioned purpose, will inevitably cause bursting of thermal-collecting tube.
The patent No. 87210032 and 99241883.6 is glass-metal structure vacuum solar collector tubes of a kind of single-ended opening, and it is that metal inner pipe and the sealing-in of glass outer tube form opening that an end is promptly only arranged, and claims openend; At other end metal inner pipe is free state, claims free end.The outer surface coated coating for selective absorption of interior pipe, it will stand cold and hot variation, causes the variation of length, adjusts by free end, avoids glass outer tube generation stress to cause and bursts.This thermal-collecting tube only is fit in parallel, has limited its scope of application.
What patent No. ZL01224848.7 and publication number CN1321865A related to is through type (both ends open) glass-metal structure vacuum solar collector tubes, the no free end of promptly interior pipe.The length variations that causes because of cold and hot variation for pipe in eliminating at a length compensation device of an end sealing-in (bellows) of interior pipe, and then is connected with outer siphunculus.Its shortcoming be interior pipe must with the bellows hermetic seal, during sealing-in or adopt the Ar arc-welding, or adopt plasma welding, or other Qian Soldering method.Corresponding mould or anchor clamps are arranged, even annex during welding, not only increased the difficulty of cost and tubulation, and the increase of operation will inevitably have influence on the yield rate of homogeneous tube, structure as shown in Figure 1.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art and defective, a kind of novel bilateral glass-metal vacuum solar thermal-collecting tube that interior pipe and bellows are united two into one is proposed, thereby reach further simplification product structure, improve the finished product rate, the purpose that reduces production costs.
The purpose of this utility model is achieved by the following technical solution: a kind of bilateral glass-metal vacuum solar thermal-collecting tube with pipe in the direct compensation formula, mainly by the glass outer tube, the surface is coated with the metal inner pipe of coating for selective absorption, blast pipe, the outer siphunculus that links to each other with interior pipe two ends and form with the metal cap of inner and outer pipe two ends sealing-in, be vacuum interlayer between described outer tube and the interior pipe, its technical characterictic is that described metal inner pipe adopts all or part of undulatory metal tube that is.
The present invention compared with prior art, because its metal inner pipe is all or part of bellows that is processed into directly, one end of interior pipe need not a length compensation device of sealing-in again (bellows), not only inner tube structure is simple, and reduced weld seam, reduce the gas leakage probability, improved yield rate, increased the anti-pressure ability of homogeneous tube; Interior pipe unites two into one with bellows, can simplify technology, reduces cost; Can process the bellows of different length according to the condition of work of homogeneous tube on inner pipe, widen the range of application of evacuated solar collecting tube greatly.
Description of drawings
Fig. 1 is existing bilateral vacuum solar collector tubes structural representation composition.
Fig. 2 is the overall construction drawing of the utility model embodiment.
Among the figure: the 1-metal cap; 2-glass outer tube; 3, the outer siphunculus of 4-; 1,5,6,8,10-metal cap; The 7-bellows; The 9-metal inner pipe; The 11-blast pipe; The 12-getter; The 13-coating for selective absorption; The 14-vacuum interlayer; The 16-support ring; The 16-wire netting.
The specific embodiment
Below in conjunction with accompanying drawing, further specify concrete structure of the present utility model and preferred forms:
Fig. 2 is the overall construction drawing of the utility model embodiment, and it comprises glass outer tube 2, respectively the outer siphunculus 3,4 that links to each other with interior pipe two ends, the surface is coated with the metal inner pipe 9 of coating for selective absorption 13, blast pipe 11, vacuum interlayer 14, metal cap 1,5,6,8 and 10 and getter 12.Cancel bellows among the figure, directly interior pipe has been processed into bellows.This thermal-collecting tube comprises the high transparent glass outer tube 2 of sunshine and has the high metal inner pipe 9 that absorbs the sunshine effect.Glass tube 2 becomes outer tube with metal cap 1 sealing by fusing, keeps airtight; Metal cap 6 and blast pipe 11 sealing-ins keep airtight; Outer siphunculus 3 respectively with metal cap 5 and 8 sealing-ins, keep airtight; Outer siphunculus 4 respectively with metal cap 6 and 10 sealing-ins, keep airtight; Make airtight welded pipe with sheet metal strip, become undulatory interior pipe 9, high annealing afterwards with bloated type processes; Cooling final vacuum plating coating for selective absorption; At least one end points at interior pipe welds non-nonevaporable getter agent 12.With the two ends of interior pipe respectively with metal cap 8 and 10 sealing-ins, keep airtight; With metal cap 1 and 5, metal cap 1 and 6 sealing-ins keep airtight.Gap between the inner and outer pipe vacuumizes, and forms vacuum interlayer 14.
The utility model can be operated in high, medium and low temperature range condition according to thermal-collecting tube, promptly need to adjust the scope of its length, the bloated type processes of its all or part of usefulness is become corrugated, and annealing at high temperature, the direct outer wall coated coating for selective absorption of pipe whole in forms the height absorption metal inner pipe that self has its length variations function of compensation then.
