Description
Technical field
Solar vacuum heat-collecting pipe technical field is the utility model is related to, it is true more particularly, to a kind of resistant to elevated temperatures solar energy
Empty set heat pipe end protection structure.
Background technology
The sealing-in position of solar energy heating tube end can cut down sealing-in outer tube by stainless steel metal inner tube, glass and incite somebody to action both
Flanged (FLGD) bellows for connecting is formed, and it is lower that bellows and sealing-in can cut down ring antibody Monoclonal ability, can neither be through
Also being unable to undergo overheat by the effect of big external force is influenceed, but in storage and transportation, the sealing-in position of thermal-arrest tube end
Certain external force is inevitably born, if being easy for causing the position distortions and rupture without certain safeguard measure；
On the other hand, under solar vacuum heat-collecting pipe normal operating conditions, the Salar light-gathering speculum with the supporting setting of thermal-collecting tube
The strong sunshine reflected can be irradiated to sealing-in position, and sealing-in position is chronically under hot conditions in the course of time unavoidably can be to envelope
Socket part position damages, and destroys the sealing property at sealing-in position, ultimately results in the vacuum expendable pattern of solar vacuum heat-collecting pipe, seriously
The collecting efficiency of thermal-collecting tube is influenceed, so as to reduce generated output.Applied at present in solar energy vacuum heat collecting system on the market
Protection structure and sealing-in position are mostly Hard link at the sealing-in of end, and when external force acts on protection structure, protection structure is easily external force
Sealing-in position is directly conducted to, so as to cause the damage at sealing-in position, and traditional end protection structure uses individual layer material more
Matter, effect of heat insulation are limited, it is impossible to which good tamper seal socket part position is not susceptible to overheating, in summary, it is now desired to which one kind was both
The thermal-arrest tube end protection structure that external force influences and has more preferable effect of heat insulation can be effectively reduced.
Utility model content
For problems of the prior art, the purpose of this utility model is to provide a kind of resistant to elevated temperatures solar energy true
Empty set heat pipe end protection structure, so as to effectively reduce high temperature and external force to being brought at the sealing-in of solar vacuum heat-collecting pipe end
Harmful effect.
To achieve the above object, the technical solution of the utility model is：
A kind of resistant to elevated temperatures solar vacuum heat-collecting pipe end protection structure, it includes being socketed on solar vacuum heat-collecting pipe
Cylindrical cover body on the outside of sealing-in position and several potsherds for being laid in the cover body periphery, at left and right sides of the cover body
It is open, opening is further fixedly arranged on the spring for being connected with the solar vacuum heat-collecting tube sealing position on the left of cover body
Piece, the cover body are rolled by the stainless steel plate with cavity and formed, between the potsherd and potsherd by can bending not
The steel bar that becomes rusty connects, and the potsherd corner and stainless steel strip both ends offer identical through hole, fixing bolt are provided with through hole,
Nut is provided with fixing bolt.
Further, the cover body internal diameter is more than solar vacuum heat-collecting tube glass outer tube external diameter 5mm -10mm, and cover body is normal
Length under temperature is more than the length at sealing-in position.
Further, the spring leaf is made up of the multiple bending of stainless steel substrates, and spring leaf is welded in sealing-in position bellows
On outward flange disk.
Further, the stainless steel strip includes long stainless steel strip and short stainless steel strip.
Above-mentioned technical proposal of the present utility model has the advantages that：The utility model is protected end using spring leaf
Protection structure flows through journey medial end portions sealing-in with being connected at the sealing-in of solar vacuum heat-collecting pipe end, even in storage and transport
By external impacts, spring leaf can also effectively reduce external force to the influence at sealing-in at place；On the other hand, in the operating condition,
The potsherd of periphery laying is it is possible to prevente effectively from solar light focusing is irradiated at sealing-in, and has the heat transfer efficiency phase of the cover body of cavity
Substantially reduced for individual layer cover body, effectively protect and be not susceptible to overheating at sealing-in.By the sun with this end construction
Energy vacuum heat collection pipe loads experimental power station loop, and thermal-collecting tube is without damaged and vacuum expendable pattern phenomenon, this Shen after running a period of time
Please be novel in design, it is durable, there is very strong practicality.
