Description
Technical field
The present invention relates to the eccentric vacuum heat collection pipe 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 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.
Summary of the invention
The objective of the invention is to provide built-in independent minute surface eccentric vacuum heat collection pipe.
The present invention solves the technical scheme of its technical problem: the cover glass tube with end circle envelope is tightly connected into an eccentric chuck with the inner glass tube nested arrangement, 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; To sealed-off after the inner baking of the eccentric chuck exhaust, make an eccentric vacuum heat collection pipe of built-in independent minute surface.Be manufactured with absorbing film on the inner glass tube, the inner glass tube of band absorbing film is connected with the minute surface optically focused on the described half slot shape object concave surface.
Can also make described inner glass tube be curved inner glass tube; Described curved inner glass tube is by eccentric straight section, and outer straight section constitutes with the bending section that is connected eccentric straight section and outer straight section; Described eccentric straight section has absorbing film, and the described eccentric straight section that has absorbing film is connected with described minute surface optically focused.
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.
Beneficial effect of the present invention: 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.

The specific embodiment
Fig. 1 provides first embodiment of the present invention.
Among Fig. 1, with the cover glass tube 1 of end circle envelope and directly inner glass tube 2 nested arrangement be tightly connected into an eccentric chuck, at the cover glass tube 1 inwall half slot shape object 3 that is connected, the concave surface of half slot shape object 3 has minute surface 4; Half slot shape object 3 usefulness jump rings 5 are against cover glass tube 1 inboard the realization and are connected; To sealed-off after the inner baking of the eccentric chuck exhaust, make the eccentric vacuum heat collection pipe of a built-in independent minute surface.Be manufactured with absorbing film on the straight inner glass tube 2, the straight inner glass tube 2 of band absorbing film is connected with minute surface 4 optically focused on half slot shape object 3 concave surfaces.
The axial line that optically focused of the present invention connects, and refers to the tubulose absorber---refer to be eccentric straight section 4 with the straight inner glass tube 2(of absorbing film in embodiment 2 in embodiment 1)---is mobile near the minute surface 4 on the concave surface of half slot shape object 3 but do not contact in order to avoid form heat bridge with minute surface 4 and cause heat-energy losses from the top down along the symmetrical plane of minute surface 4.Can recognize from each accompanying drawing of the present invention: enter the sunlight of cover glass tube 1 the latter half, mid portion directly for example changes into heat energy with the straight inner glass tube 2 of absorbing film at absorber; The overwhelming majority in the two side portions arrives on the absorber through the reflection of minute surface 4 once or repeatedly and changes into heat energy.The sunlight that passes from the gap between absorber and the cover glass tube 1 might pass through the reflection of minute surface 4 and escape from cover glass tube 1.Usually the gap width between absorber and the cover glass tube 1 is 1 to 2 millimeter.
Fig. 2 provides second embodiment of the present invention.
Among Fig. 2, adopt one by eccentric straight section 6, the curved inner glass tube 9 of outer straight section 7 and bending section 8 formations that are connected eccentric straight section 6 and outer straight section 7; The curved inner glass tube 9 of order is tightly connected into an eccentric chuck with cover glass tube 1 nested arrangement of end circle envelope, the half slot shape object 3 that is connected in cover glass tube 1 the inside, and the concave surface of half slot shape object 3 is manufactured with minute surface 4; Half slot shape object 3 usefulness jump ring circles 5 are against cover glass tube 1 inboard the realization and are connected; Cover glass tube 1 contains a undergauge section 10 near sealing-in place; The port of the waist of outer straight section 7 and cover glass tube 1 melts envelope and connects into an eccentric chuck; The high bead of outer straight section 7 protruding formation; To sealed-off after the inner baking of the eccentric chuck exhaust; Make the eccentric vacuum heat collection pipe of the curved inner glass tube of the high bead of undergauge of a built-in independent minute surface.Be manufactured with absorbing film on the eccentric straight section 6, the eccentric straight section 6 of band absorbing film is connected with minute surface 4 optically focused on half slot shape object 3 concave surfaces.The axial line of outer straight section 7 overlaps with cover glass tube 1.
The cover glass tube 1 of Fig. 2 embodiment has undergauge section 10, and the external diameter of undergauge section 10 is bigger 10 millimeters than outer straight section 7, and the diameter of itself and curved inner glass tube 7 is more approaching, and both sealing-in difficulty are reduced greatly.
