Abstract
Provided is a hole-shrinkage bending inner glass tube eccentric heat tube evacuated collector tube with an externally plated mirror surface. A bending inner glass tube 4 is formed by an eccentric straight section 1, an outer straight section 2 and a bending section 3 connecting the eccentric straight section 1 and the outer straight section 2, the bending inner glass tube 4 and a glass tube cover 5 with a circularly sealed end are arranged in a nested and eccentric mode, the outer straight section 2 extends out of the circularly sealed end, the waist portion of the outer straight section 2 and the end of the glass tube cover 5 are sealed and connected in a fused mode to form an eccentric clamp sleeve, and the mirror surface 6 is manufactured on the outer surface of the glass tube cover 5 within the range of about 180-degree circumference angle. The glass tube cover 5 is provided with a hole-shrinkage section 7 close to the sealing connection position. The inside of the eccentric clamp sleeve is baked to exhaust air, and then the eccentric clamp sleeve is sealed. The bending inner glass tube 4 is vacuumized, filled with a working medium and sealed, and therefore the hole-shrinkage bending inner glass tube eccentric heat tube evacuated collector tube with the externally plated mirror surface is manufactured. An absorption film is manufactured on the eccentric straight section 1 of the bending inner glass tube 4, and the mirror surface 6 is provided with a protective coating. The eccentric straight section 1 with the absorption film is connected with the mirror surface 6 in a condensation mode.
Description
Technical field
The present invention relates to the eccentric heat-pipe vacuum heat collecting pipe of the curved inner glass tube of outer plating minute surface undergauge.
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.In addition, be utilization and extention solar energy, should the more eccentric thermal-collecting tube product of Development and Production.
Summary of the invention
[0003] the object of the invention is to provide the curved inner glass tube of outer plating minute surface undergauge eccentric heat-pipe vacuum heat collecting pipe.
The present invention solves the technical scheme of its technical problem: adopt one by eccentric straight section, the curved inner glass tube that outer straight section forms with the bending section that is connected eccentric straight section and outer straight section, with the nested arranged off-centre of cover glass tube of one end circle envelope, the protruding circle envelope of described 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 cover glass tube outer surface of approximately 180 degree angle of circumference scopes is manufactured with minute surface; Cover glass tube is made a undergauge section near sealing-in place; To sealed-off after the inner baking of eccentric chuck exhaust; To the sealed-off of the inner vacuum pumping loading working medium of curved inner glass tube, make an eccentric heat-pipe vacuum heat collecting pipe of the curved inner glass tube of outer plating minute surface undergauge.On the eccentric straight section of described curved inner glass tube, be manufactured with absorbing film, described minute surface is with protective finish; Eccentric straight section with absorbing film is connected with described minute surface optically focused.
Can also make described minute surface is Magnetron Sputtered Al film mirror.
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.With two sections of glass tube arranged concentric of its sealing-in of eccentric thermal-collecting tube of curved inner glass tube, conveniently melt envelope operation.Cover glass tube adopts undergauge section, and the diameter of undergauge section and curved inner glass tube is more approaching, and both sealing-in difficulty are reduced greatly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the eccentric heat-pipe vacuum heat collecting pipe composite construction of the curved inner glass tube of an outer plating minute surface undergauge schematic diagram.
1. eccentric straight sections in figure; 2. outer straight section; 3. bending section; 4. curved inner glass tube; 5. cover glass tube; 6. minute surface; 7. undergauge section.
The specific embodiment
Fig. 1 provides first embodiment of the present invention.
In Fig. 1, adopt one by eccentric straight section 1, the curved inner glass tube 4 that outer straight section 2 forms with the bending section 3 that is connected eccentric straight section 1 and outer straight section 2, with the nested arranged off-centre of cover glass tube 5 of one end circle envelope, the protruding circle of outer straight section 2 seals; 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; Cover glass tube 5 outer surfaces of approximately 180 degree angle of circumference scopes are manufactured with minute surface 6; Cover glass tube 5 is made a undergauge section 7 near sealing-in place; To sealed-off after the inner baking of eccentric chuck exhaust; To the sealed-off of the inner vacuum pumping loading working medium of curved inner glass tube 4, make an eccentric heat-pipe vacuum heat collecting pipe of the curved inner glass tube of outer plating minute surface undergauge.On the eccentric straight section 1 of curved inner glass tube 4, be manufactured with absorbing film, minute surface 6 is with protective finish; Eccentric straight section 1 with absorbing film is connected with minute surface 6 optically focused.
In Fig. 1, outside arrow represents the cold junction of heat pipe side by side.
Optically focused of the present invention connects, and refers to tubulose absorber, for example mobile near cover glass tube 5 but do not contact in order to avoid form heat bridge and cause heat-energy losses with cover glass tube 5 from the top down along the symmetrical plane of minute surface 6 with the axial line of the eccentric straight section 1 of absorbing film.From Fig. 1, can recognize: enter the sunlight of cover glass tube 5 the latter halfs, mid portion directly for example changes into heat energy on eccentric straight section 1 at absorber; The overwhelming majority in two side portions arrives on absorber and changes into heat energy through the reflection of minute surface 6 once or repeatedly.The sunlight passing from the gap between absorber and cover glass tube 5 likely passes through the reflection of minute surface 6 and escapes from cover glass tube 5.Conventionally the gap width between tubulose absorber and cover glass tube 5 is 1 to 2 millimeter.
