Abstract
Provided is an outer attaching mirror face high edge opening bending inner glass pipe eccentric vacuum heat collecting pipe. A bending inner glass pipe formed by an eccentric straight section, an outer straight section and a bending section which connects the eccentric straight section and the outer straight section is used for being arranged with a sleeve glass pipe with one end in circular sealing in an embedding mode. The waist portion of the outer straight section and a port of the sleeve glass pipe are connected in a melt sealing mode to form an eccentric clamping sleeve. The outer straight section extends out to form a high edge opening. The heat collecting pipe is formed after baking exhausting is carried out in the eccentric clamping sleeve in a sealing-off mode. The outer attaching mirror face high edge opening bending inner glass pipe eccentric vacuum heat collecting pipe is characterized in that a semi-circular groove-shaped object is connected to the outer surface of the sleeve glass pipe in a matching mode, a mirror face is manufactured on the inner-concave surface of the semi-circular groove-shaped object, an absorbing film is arranged on the eccentric straight section of the bending inner glass pipe, and the eccentric straight section with the absorbing film and the mirror face on the inner-concave surface of the semi-circular groove-shaped object are connected in a light-focusing mode. The semi-circular mirror face is manufactured on the outer portion of the sleeve glass pipe, and the design freedom of the technology is greatly improved.
Description
Technical field
The present invention relates to the outer eccentric vacuum heat collection pipe of the curved inner glass tube of the high bead of minute surface that pastes.
Background technology
The eccentric all-glass vacuum thermal-collecting tube of settling of existing a kind of inner glass tube claims eccentric thermal-collecting tube again.The diameter of its inner glass tube is about half of cover glass tube, the semicircle AM aluminum metallization minute surface optically focused that utilizes cover glass tube inwall thermal-arrest to the absorbing film on inner glass tube surface has advantages such as less with material, that the few little startup of the little heat waste of heat sink little surface area of the little water of inner glass tube cavity is fast.But the semicircle AM aluminum metallization minute surface of its cover glass tube inwall employing high-frequency induction is built in the hot boat heating in the cover glass tube, and makes the aluminium thawing generation aluminium steam in the hot boat form semicircle plated film layer at the cover glass tube inwall under high vacuum condition.The equipment manufacturing cost height that this production technology relates to once can only evaporation one arm, and the inconvenient grafting magnetron sputtering of this technology etc. is efficient, the coating process of excellent performance.Influenced the raising of eccentric thermal-collecting tube production efficiency.In addition, be utilization and extention solar energy, should the more eccentric thermal-collecting tube product of Development and Production.
Summary of the invention
The objective of the invention is to provide the outer eccentric vacuum heat collection pipe of the curved inner glass tube of the high bead of minute surface that pastes.
The present invention solves the technical scheme of its technical problem: adopt one by eccentric straight section, the curved inner glass tube of outer straight section and the bending section formation that is connected eccentric straight section and outer straight section is with the cover glass tube nested arrangement of an end circle envelope; The waist of described outer straight section and the port of cover glass tube melt envelope and are connected to form an eccentric chuck; Described outer straight section stretches out and forms high bead; To sealed-off after the inner baking of the eccentric chuck exhaust, make an outer eccentric vacuum heat collection pipe of the curved inner glass tube of the high bead of minute surface that pastes.At the cover glass tube outer surface half slot shape object that is connected, the concave surface of described half slot shape object is manufactured with minute surface; Have absorbing film on the eccentric straight section of described curved inner glass tube, the eccentric straight section of described band absorbing film is connected with minute surface optically focused on the described half slot shape object concave surface.
Can also make cover glass tube contain a undergauge section near sealing-in place.
Can also make described half slot shape object adopt the silica gel bonding in its edge and cover glass tube outer surface.
Beneficial effect of the present invention: the outside at cover glass tube makes the semicircle minute surface, and the design freedom of technology increases greatly.Can directly adopt the existing a large amount of vacuum magnetic-control sputtering filming equipments that use once tens of make minute surface at the cover glass tube outer surface, work efficiency is increased to 2,000 from about 500 of unit every day.Can also adopt existing aluminium film evaporation streamline high speed evaporation minute surface on the concave surface of half slot shape object, work efficiency was increased to more than 10,000 from 500 of unit every days.Production efficiency increase substantially the reduction that means product cost.Have two sections glass tube arranged concentric of eccentric its sealing-in of thermal-collecting tube of curved inner glass tube, conveniently melt the envelope operation.Cover glass tube adopts the undergauge section, and the diameter of undergauge section and curved inner glass tube is more approaching, and both sealing-in difficulty are reduced greatly.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described.
Fig. 1 is the outer eccentric vacuum heat collection pipe composite construction of the curved inner glass tube of the high bead undergauge of a minute surface schematic diagram that pastes.
1. eccentric straight sections among the figure; 2. outer straight section; 3. bending section; 4. bend inner glass tube; 5. cover glass tube; 6. high bead; 7. undergauge section; 8. half slot shape object; 9. minute surface.
The specific embodiment
Fig. 1 provides one embodiment of the present of invention.
Among Fig. 1, adopt one by eccentric straight section 1, the curved inner glass tube 4 of outer straight section 2 and bending section 3 formations that are connected eccentric straight section 1 and outer straight section 2 is with cover glass tube 5 nested arrangement of an end circle envelope; The port of the waist of outer straight section 2 and cover glass tube 5 melts envelope and is connected to form an eccentric chuck; Outer straight section 2 stretches out and forms high bead 6; Cover glass tube 5 contains a undergauge section 7 near sealing-in place; To sealed-off after the inner baking of the eccentric chuck exhaust, make an outer eccentric vacuum heat collection pipe of the curved inner glass tube of the high bead of minute surface that pastes.At the cover glass tube 5 outer surfaces half slot shape object 8 that is connected, the concave surface of half slot shape object 8 adopts magnetron sputtering aluminium membrane process to make a minute surface 9.Half slot shape object 8 adopts the silica gel bonding in its edge and cover glass tube 5 outer surfaces.Have absorbing film on the eccentric straight section 1 of curved inner glass tube 4, the eccentric straight section 1 of band absorbing film is connected with minute surface 9 optically focused on half slot shape object 8 concave surfaces.About 0.2 micron of the thickness of magnetron sputtering aluminium film mirror.
Optically focused of the present invention connects, and refers to the tubulose absorber, and for example the axial line of eccentric straight section 1 is mobile near cover glass tube 5 but do not contact in order to avoid form heat bridge with cover glass tube 5 and cause heat-energy losses from the top down along the symmetrical plane of minute surface 9.Can recognize from accompanying drawing of the present invention: enter the sunlight of cover glass tube 5 the latter halfs, mid portion directly for example changes into heat energy with the eccentric straight section 1 of absorbing film at absorber; The overwhelming majority in the two side portions arrives on the absorber through the reflection of minute surface 9 once or repeatedly and changes into heat energy.The sunlight that passes from the gap between absorber and the cover glass tube 5 might pass through the reflection of minute surface 9 and escape from cover glass tube 5.Usually the gap width between tubulose absorber and the cover glass tube 5 is 1 to 2 millimeter.
