Abstract
The utility model discloses an external-plating mirror surface eccentric heat-tube vacuum heat collector tube which is forming by nesting and eccentrically arranging a covered glass tube of which one end is circularly sealed and an internal glass tube, connecting the waist of the internal glass tube and a port of the covered glass tube in a sealing manner to form an eccentric jacket, baking, exhausting and sealing the interior of the eccentric jacket, vacuumizing the interior of the internal glass tube and filling a working medium and sealing, wherein an absorption film is manufactured on the internal glass tube. The external plating mirror surface eccentric heat-tube vacuum heat collector tube is characterized in that a mirror surface is manufactured on the outer surface of the covered glass tube in a range of a circumference angle being about 180 degrees; the mirror surface is provided with a protective coating; the internal glass tube with the absorption film is in condensing connection with the mirror surface.
Description
Technical field
The utility model relates to the eccentric heat-pipe vacuum heat collecting pipe of outer plating 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.In addition, the product line of eccentric thermal-collecting tube horn of plenty more.
Summary of the invention
The purpose of this utility model is to provide outer plating minute surface eccentric heat-pipe vacuum heat collecting pipe.
The technical scheme in the invention for solving the technical problem: with the nested arranged off-centre with inner glass tube of cover glass tube of an end circle envelope, the waist of inner glass tube and the port of cover glass tube melt envelope and connect into an eccentric chuck, to sealed-off after the inner baking of the eccentric chuck exhaust; Inner glass tube inside is vacuumized sealed-off after the can working medium; The cover glass tube outer surface of about 180 degree angle of circumference scopes is manufactured with minute surface, makes an eccentric heat-pipe vacuum heat collecting pipe of outer plating minute surface.Make absorbing film on the inner glass tube.Described minute surface has protective finish.The inner glass tube of band absorbing film is connected with described minute surface optically focused.
Can also make that described minute surface is magnetron sputtering aluminium film mirror.
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; Protruding and the curved inner glass tube inside of described outer straight section vacuumizes sealed-off after the can working medium.
The beneficial effects of the utility model: 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.

The specific embodiment
Fig. 1 provides first embodiment of the present utility model.
Among Fig. 1, with cover glass tube 1 and the straight inner glass tube 2 nested arranged off-centre of an end circle envelope, the waist of straight inner glass tube 2 and the port of cover glass tube 1 melt envelope and connect into an eccentric chuck; To sealed-off after the inner baking of the eccentric chuck exhaust; Straight inner glass tube 2 inside are vacuumized sealed-off after the can working medium; The cover glass tube 1 outer surface magnetron sputtering layer of aluminum film of about 180 degree angle of circumference scopes forms a semicircular minute surface 3, makes an eccentric heat-pipe vacuum heat collecting pipe of outer plating 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 3 optically focused.Minute surface 3 has protective finish.
Optically focused of the present utility model connects, and refers to the tubulose absorber, and the axial line of for example straight inner glass tube 2 is mobile near cover glass tube 1 but do not contact in order to avoid form heat bridge with cover glass tube 1 and cause heat-energy losses from the top down along the symmetrical plane of minute surface 3.Can recognize from each accompanying drawing of the present utility model: 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 3 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 3 and escape from cover glass tube 1.Usually the gap width between tubulose absorber and the cover glass tube 1 is 1 to 2 millimeter.
