Summary of the invention
The purpose of this utility model is the eccentric vacuum heat collection pipe of outer plating minute surface that the band containment vessel will be provided.
The technical scheme in the invention for solving the technical problem: the cover glass tube with an 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, make the eccentric vacuum heat collection pipe of outer plating minute surface of a band containment vessel.Be manufactured with absorbing film on the inner glass tube.The cover glass tube outer surface of about 180 degree angle of circumference scopes has minute surface, and described minute surface has protective finish, and covering place of described protective finish is connected with a half slot shape containment vessel; Described half slot shape containment vessel is made of anodised aluminium sheet; The inner glass tube of band 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.
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; The port sealing-in of the waist of described outer straight section and cover glass tube; Described curved inner glass tube inside 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.Two sections glass tube arranged concentric of eccentric its sealing-in of thermal-collecting tube of bend pipe are conveniently melted the envelope operation in having.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.Anodised aluminium sheet semicircle shape containment vessel good weatherability.
