Description
Technical field
The utility model relates to the eccentric vacuum heat collection pipe of the curved inner glass tube of the high bead of built-in independent minute surface.
Background technology
The eccentric all-glass vacuum thermal-collecting tube of settling of existing a kind of inner glass tube is called for short eccentric thermal-collecting tube.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, the kind of eccentric thermal-collecting tube also should be abundanter.
Summary of the invention
The purpose of this utility model is to provide the curved inner glass tube of the high bead of built-in independent minute surface eccentric vacuum heat collection pipe.
The technical scheme in the invention for solving the technical problem: make the eccentric vacuum heat collection pipe of the curved inner glass tube of a high bead of built-in independent minute surface, comprise the cover glass tube of curved inner glass tube and end circle envelope.Curved inner glass tube is made of eccentric straight section, outer straight section and the bending section that is connected eccentric straight section and outer straight section.The waist of described outer straight section and the port of cover glass tube melt envelope and are connected to form an eccentric chuck, the high bead of the protruding formation of described outer straight section.Be connected with a half slot shape object in the cover glass tube the inside, the concave surface of described half slot shape object is manufactured with minute surface; Be manufactured with absorbing film on the described eccentric straight section, the eccentric straight section of band absorbing film is connected with the 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 the material of described half slot shape object be high saturating glass, described minute surface is made in concave surface or the convex surface of described half slot shape object.
The beneficial effects of the utility model: at the cover glass tube inwall half slot shape object that is connected, the concave surface of described half slot shape object has minute surface, can carry out changing in the cover glass tube outside in cover glass tube internal production semicircle minute surface process originally, the design freedom of technology is increased greatly.Can directly adopt the existing a large amount of vacuum magnetic-control sputtering filming equipments that use once tens of produce, 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.The half slot shape object of a band semicircle minute surface is set in the vacuum environment in cover glass tube, can makes the semicircle minute surface avoid the corrosion influence of atmosphere, almost infinitely prolong service life.Two sections glass tube arranged concentric of eccentric its sealing-in of thermal-collecting tube of bend pipe in having, convenient working.Cover glass tube has the undergauge section, and the external diameter of undergauge section is bigger 10 millimeters than described outer straight section, and both sealing-in difficulty are reduced greatly.The eccentric thermal-collecting tube of high bead can be made the solar water heater that only the high bead of thermal-collecting tube is inserted the water tank round, both can make the thermal-collecting tube solid matter, can reduce the jack sectional area of water tank again to reduce heat waste.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the eccentric vacuum heat collection pipe composite construction of the curved interior glass of the high bead of undergauge of built-in band semicircle minute surface groove shape object schematic diagram.
1. eccentric straight sections among the figure; 2. outer straight section; 3. bending section; 4. bend inner glass tube; 5. cover glass tube; 6. half slot shape object; 7. minute surface; 8. jump ring circle; 9. undergauge section.
The specific embodiment
Fig. 1 provides an embodiment of the present utility model.
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; Cover glass tube 5 nested arrangement with an end circle envelope.The half slot shape object 6 that is connected in cover glass tube 5 the insides, the concave surface of half slot shape object 6 is manufactured with minute surface 7.Half slot shape object 6 usefulness jump ring circles 8 are against cover glass tube 5 inboard realizations and are connected.Cover glass tube 5 contains a undergauge section 9 near sealing-in place.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; The high bead of outer straight section 2 protruding formation; To sealed-off after the inner baking of the eccentric chuck exhaust; Make the eccentric vacuum heat collection pipe of the curved interior glass of the high bead of undergauge of a built-in independent minute surface.Be manufactured with absorbing film on the eccentric straight section 1, the eccentric straight section 1 of band absorbing film is connected with semicircle minute surface 7 optically focused on half slot shape object 6 concave surfaces.The axial line of outer straight section 2 overlaps with cover glass tube 5.
Optically focused of the present utility model connects, and refers to that the tubulose absorber is namely mobile near minute surface 7 but do not contact in order to avoid form heat bridge with minute surface 7 and cause heat-energy losses from the top down along the symmetrical plane of semicircular minute surface 7 with the axial line of the eccentric straight section 1 of absorbing film.Can recognize from accompanying drawing of the present utility model: enter the sunlight of cover glass tube 5 the latter halfs, mid portion directly changes into heat energy at absorber; The overwhelming majority in the two side portions arrives on the absorber through the reflection of minute surface 7 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 7 and escape from cover glass tube 5.Usually the gap width between absorber and the cover glass tube 5 is 1 to 2 millimeter.
