Abstract
The utility model discloses an external-attached mirror surface eccentric vacuum heat collector tube. The vacuum heat collector tube is formed by nesting and connecting a covered glass tube of which one end is circularly sealed and an internal glass tube in a sealing manner to form an eccentric jacket, and baking, exhausting and sealing the interior of the eccentric jacket, wherein an absorption film is manufactured on the internal glass tube. The vacuum heat collector tube is characterized in that a semicircular slotted object is connected to the outer surface of the covered glass tube in a matching mode, wherein the inwards concave surface of the semicircular slotted object contains a mirror surface; the internal glass tube with the absorption film is in condensing connection with the mirror surface on the inwards concave surface of the semicircular slotted object.
Description
Technical field
The utility model relates to the outer eccentric vacuum heat collection pipe 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.
Summary of the invention
The purpose of this utility model is that the outer eccentric vacuum heat collection pipe of minute surface that pastes will be provided.
The technical scheme in the invention for solving the technical problem: the cover glass tube with end circle envelope is tightly connected into an eccentric chuck with the inner glass tube nested arrangement, to sealed-off after the inner baking of the eccentric chuck exhaust, 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, makes the eccentric vacuum heat collection pipe of evaporation minute surface in the non-pipe.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 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 inner can working medium that vacuumizes of described outer straight section seals.
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.

The specific embodiment
Fig. 1 provides first embodiment of the present utility model.
Among Fig. 1, cover glass tube 1 with end circle envelope is tightly connected into an eccentric chuck with straight inner glass tube 2 nested arrangement, to sealed-off after the inner baking of the eccentric chuck exhaust, at the cover glass tube 1 outer surface half slot shape object 3 that is connected, the concave surface of described half slot shape object 3 is manufactured with minute surface 4, makes the eccentric vacuum heat collection pipe of evaporation minute surface in the non-pipe.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 described half slot shape object 3 concave surfaces.Half slot shape object 3 adopts the silica gel bonding in edge and cover glass tube 1 outer surface.
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 4.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.
Fig. 2 provides second embodiment of the present utility model.
Among Fig. 2, adopt one by eccentric straight section 5, the curved inner glass tube 8 of outer straight section 6 and bending section 7 formations that are connected eccentric straight section 5 and outer straight section 6, with the cover glass tube 1 nested arranged off-centre of an end circle envelope, outer straight section 6 protruding circles seal; The port of the waist of outer straight section 6 and cover glass tube 1 melts envelope and is connected to form an eccentric chuck; Cover glass tube 1 is made a undergauge section 9 near sealing-in place, and the external diameter of undergauge section 9 is bigger 10 millimeters than outer straight section 6.To sealed-off after the inner baking of the eccentric chuck exhaust; Curved inner glass tube 8 inside are vacuumized can working medium melt envelope; At the cover glass tube 1 outer surface half slot shape object 3 that is connected, the concave surface of half slot shape object 3 is manufactured with minute surface 4, makes an outer eccentric heat-pipe vacuum heat collecting pipe of the curved inner glass tube of undergauge that pastes minute surface.Be manufactured with absorbing film on the eccentric straight section 5 of curved inner glass tube 8, the eccentric straight section 5 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 6 overlaps with cover glass tube 1.
Among Fig. 2, outside arrow is represented the cold junction of heat pipe side by side.
Among Fig. 2, cover glass tube 1 adopts undergauge section 9, and undergauge section 9 is more approaching with the diameter of outer straight section 6, and both sealing-in difficulty are reduced greatly.
