A glass tube cover 1 with a circularly sealed one and an inner glass tube are arranged in a nested mode and connected in an eccentric mode to form an eccentric clamp sleeve, the inside of the eccentric clamp sleeve is baked to exhaust air, and then the eccentric clamp sleeve is sealed. An absorption film is manufactured on the inner glass tube. The eccentric evacuated collector tube with the externally attached mirror surface is characterized in that the outer surface of the glass tube cover 1 is connected with a semi-circular groove-shaped article 3 in a matched mode, the mirror surface 4 is manufactured on the inwards concaved surface of the semi-circular groove-shaped article 3, and the inner glass tube with the absorption film is connected with the mirror surface 4 on the inwards concaved surface of the semi-circular groove-shaped article 3 in a condensation mode.
Description
Technical field
The present invention relates to the eccentric vacuum heat collection pipe of outer subsides minute surface.
Background technology
The eccentric all-glass vacuum thermal-collecting tube of settling of existing a kind of inner glass tube, claims again eccentric thermal-collecting tube.The diameter of its inner glass tube is about half of cover glass tube, utilize the semicircle AM aluminum metallization minute surface of cover glass tube inwall to be converged to thermal-arrest on the absorbing film on inner glass tube surface, there is the advantages such as less with material, 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 adopts high-frequency induction to be built in the hot boat heating in cover glass tube, and make the aluminium thawing generation aluminium steam in hot boat at cover glass tube inwall, form semicircle film plating layer under high vacuum condition.The equipment manufacturing cost that this production technology relates to is high, once can only evaporation one arm, and the inconvenient grafting magnetron sputtering of this technique etc. is efficient, the coating process of excellent performance.Affected the raising of eccentric thermal-collecting tube production efficiency.
Summary of the invention
The object of the invention is to provide outer subsides minute surface eccentric vacuum heat collection pipe.
The present invention solves the technical scheme of its technical problem: with the cover glass tube of one end circle envelope, be tightly connected into an eccentric chuck with inner glass tube nested arrangement, to sealed-off after the inner baking of 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 a non-pipe.On inner glass tube, be manufactured with absorbing film; Inner glass tube with absorbing film is connected with the minute surface optically focused on described half slot shape object concave surface.
Can also make described inner glass tube is curved inner glass tube; Described curved inner glass tube is by eccentric straight section, and outer straight section forms with the bending section that is connected eccentric straight section and outer straight section; Described eccentric straight section is with absorbing film, and the described eccentric straight section with absorbing film is connected with described minute surface optically focused.
Can also make described inner glass tube is curved inner glass tube; Described curved inner glass tube is by eccentric straight section, and outer straight section forms with the bending section that is connected eccentric straight section and outer straight section; Described eccentric straight section is with absorbing film, and the described eccentric straight section with absorbing film is connected with described minute surface optically focused; Protruding and the inner vacuum pumping loading working medium sealing of described outer straight section.
Beneficial effect of the present invention: the outside at cover glass tube makes semicircle minute surface, and the design freedom of technique increases greatly.The vacuum magnetron sputtering coating film equipment that can directly adopt existing a large amount of uses once tens of at cover glass tube outer surface, make minute surface, work efficiency is increased to 2,000 from approximately 500 of unit every days.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.

1. cover glass tubes in figure; 2. straight inner glass tube; 3. half slot shape object; 4. minute surface; 5. eccentric straight section; 6. outer straight section; 7. bending section; 8. curved inner glass tube; 9. undergauge section.
The specific embodiment
Fig. 1 provides first embodiment of the present invention.
In Fig. 1, with the cover glass tube 1 of one end circle envelope, be tightly connected into an eccentric chuck with straight inner glass tube 2 nested arrangement, to sealed-off after the inner baking of 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 a non-pipe.On straight inner glass tube 2, be manufactured with absorbing film; Straight inner glass tube 2 with 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 silica gel bonding in edge and cover glass tube 1 outer surface.
Optically focused of the present invention connects, and refers to tubulose absorber, and the axial line of for example straight inner glass tube 2 moves from the top down near cover glass tube 1 but do not contact in order to avoid form heat bridge and cause heat-energy losses with cover glass tube 1 along the symmetrical plane of minute surface 4.From each accompanying drawing of the present invention, can recognize: enter the sunlight of cover glass tube 1 the latter half, mid portion directly for example changes into heat energy on the straight inner glass tube 2 with absorbing film at absorber; The overwhelming majority in two side portions arrives on absorber and changes into heat energy through the reflection of minute surface 3 once or repeatedly.The sunlight passing from the gap between absorber and cover glass tube 1 likely passes through the reflection of minute surface 3 and escapes from cover glass tube 1.Conventionally the gap width between tubulose absorber and cover glass tube 1 is 1 to 2 millimeter.
Fig. 2 provides second embodiment of the present invention.
In Fig. 2, adopt one by eccentric straight section 5, the curved inner glass tube 8 that outer straight section 6 forms with the bending section 7 that is connected eccentric straight section 5 and outer straight section 6, with the nested arranged off-centre of cover glass tube 1 of one end circle envelope, the protruding circle of outer straight section 6 seals; 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 than large 10 millimeters of outer straight section 6.To sealed-off after the inner baking of eccentric chuck exhaust; The inner vacuum pumping loading working medium of curved inner glass tube 8 is melted to 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.On the eccentric straight section 5 of curved inner glass tube 8, be manufactured with absorbing film, with the eccentric straight section 5 of absorbing film, be 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.
In Fig. 2, outside arrow represents the cold junction of heat pipe side by side.
In 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.
