Abstract
The invention discloses an inner protecting cover for end sealing of an evacuated solar collector tube. The inner protecting cover is mainly characterized in that the whole inner protecting cover is in a horn shape, the outer circle surface of a large-diameter position of a horn-shaped cover body of the inner protecting cover keeps a distance from the inner circle surface of an outer glass tube, the diameter of a small-diameter section of the cover body is larger than the outer diameter of an inner stainless steel tube, the small-diameter section of the cover body is fixedly connected with a flange connected with a corrugated tube and a thin-wall sealing tube, and a large-diameter horn mouth of the cover body stretches into the outer glass tube and extends until sunlight can be prevented from being reflected and irradiating the sealing portion of the thin-wall sealing tube and the outer glass tube. The inner protecting cover has the advantages of being simple in structure and reasonable in layout, effectively preventing sunlight from burning the sealing portion and the like.
Description
Technical field
The present invention relates to a kind of interior protective cover of solar vacuum heat-collecting pipe end sealing-in, belong to solar thermal utilization equipment technology.
Background technology
Sealing-in of the present invention, refers to that thin-walled sealing-in pipe 5(comprises stainless steel sealed pipe and kovar alloy sealing-in pipe) the position F(that implements sealing-in with outer glass tube 2 refers to accompanying drawing 1).
Because thin-walled sealing-in pipe 5 and outer glass tube 2, take glass hot melt to overlap sealing-in, thus both sealing-ins are quite fragile, and it can not accept the interference of super external force, is also unable to undergo overheated impact.
But, under described solar vacuum heat-collecting pipe normally runs working condition, the sunshine reflected by the Salar light-gathering speculum with its phase configuration, the sealing-in position described in it can be radiated at for a long time, so that described sealing-in position of burning, damage to described sealing-in position, destroy the sealing property at sealing-in position, finally cause the vacuum of solar vacuum heat-collecting pipe to disappear totally, had a strong impact on the collecting efficiency of described thermal-collecting tube, so that reduced the power of solar energy thermal-power-generating.
And this described sunshine is burnt the phenomenon of solar vacuum heat-collecting tube sealing, be that institute of solar energy thermal-power-generating economic entity (operator) is unacceptable.
Summary of the invention
It is simple that the present invention aims to provide a kind of structure, lays rationally, and protective cover in the solar vacuum heat-collecting pipe end sealing-in can effectively avoiding described sealing-in to be burnt by sunshine, to overcome the realistic problem that must conscientiously solve existing for prior art.
The technical scheme that the present invention realizes its object is:
A kind of interior protective cover of solar vacuum heat-collecting pipe end sealing-in; its global shape is horn-like; and its to be the outer round surface at major diameter place of horn-like cover body and the internal circular surfaces of outer glass tube keep at a distance arranges; and the large external diameter with pipe in stainless pipe of the diameter of the reduced diameter section of cover body; and be fixedly connected with the flange that bellows is connected with thin-walled sealing-in pipe; the major diameter horn mouth of described cover body stretches in outer glass tube, and reaches always and can stop the position of sunshine reflected illumination to thin-walled sealing-in pipe and outer glass tube sealing-in place.
Can be known by above given technical scheme, because the present invention will in trumpet-shaped interior protective cover, rationally and be dexterously laid in the end of outer glass tube, neither change the overall structure of original described thermal-collecting tube, hush up again described sealing-in not rightly to be sunlighted, avoided and cause burning of sealing-in; And keep at a distance between the major diameter place of described horn-like cover body and outer glass tube inwall, the vacuum dead angle of described vacuum heat collection pipe can be eliminated, make it to keep the consistent of vacuum, and make described vacuum heat collection pipe keep its normal service behaviour, thus achieve the object desired by the present invention.
The present invention further advocates:
The major diameter horn mouth of described cover body stretches into distance in outer glass tube within the scope of 5 ~ 20mm.But be not limited thereto.
The outer round surface at major diameter place of described cover body and the distance of the internal circular surfaces of outer glass tube are within the scope of 3 ~ 8mm.But be not limited thereto.
The described interior sidewall surface in trumpet-shaped cover body, in the spotlight camber throwing upper thread.Such frame mode, will improve the collecting efficiency of described vacuum heat collection pipe further.
Described cover body is aluminium matter cover body or stainless steel cover body.But be not limited thereto.
And anodic oxide coating is had in the rear surface of aluminium matter cover body, and its inner surface is minute surface.The positive effect of this technical scheme is to promote further that described cover body is anticorrosive, resistance to elevated temperatures and reflector efficiency thereof.
After technique scheme is implemented in full, the structure that the present invention has is simple, lay rationally and the sealing-in of vacuum heat collection pipe described in available protecting the feature such as not to be burnt by sunshine, is self-evident.
Accompanying drawing explanation
Fig. 1 is a kind of detailed description of the invention of the present invention and solar vacuum heat-collecting pipe assembled state schematic diagram.
Detailed description of the invention
Below contrast accompanying drawing, by the description of detailed description of the invention, the invention will be further described.
A kind of typical detailed description of the invention, as shown in Figure 1.
A kind of interior protective cover of solar vacuum heat-collecting pipe end sealing-in, its global shape is horn-like, and its to be the outer round surface at the major diameter place of horn-like cover body 1 and the internal circular surfaces of outer glass tube 2 keep at a distance arranges, and the large external diameter with pipe 3 in stainless pipe of the diameter of the reduced diameter section of cover body 1, and be fixedly connected with the flange 6 that bellows 4 is connected with thin-wall stainless steel sealing-in pipe 5, the major diameter horn mouth of described cover body 1 stretches in outer glass tube 2, and reach always and can stop that sunshine reflected illumination is to position with both outer glass tube 2 sealing-in place F of thin-wall stainless steel sealing-in pipe 5.
And the major diameter horn mouth of cover body 1 described in it stretches into distance in outer glass tube 2 within the scope of 5 ~ 20mm.
And the distance of the outer round surface at the major diameter place of cover body 1 described in it and the internal circular surfaces of outer glass tube 2 is within the scope of 3 ~ 8mm.
And the interior sidewall surface in trumpet-shaped cover body 1 described in it, in the spotlight camber throwing upper thread.
And cover body 1 described in it is aluminium matter cover body or stainless steel cover body.
And it has anodic oxide coating in the rear surface of aluminium matter cover body 1, and its inner surface is minute surface.
In above-mentioned detailed description of the invention, described horn-like cover body 1, be by aluminium plate by there is the punch of accurate light gathering reflector minute surface through being stamped to form, and stand anodized at its outer surface (non-reflective surface), and within it mirror process is implemented on surface (reflective surface).
And the thickness of described aluminium plate is within the scope of 1 ~ 2mm.
First sample of the present invention is very gratifying in effect that machine is tested.
