no. 1 example

[0043]In the first embodiment: a medium-conducting glass composite tube pressure-bearing direct-to-solar vacuum transducer tube includes a reduced-diameter nozzle 2, a variable-diameter curved surface transition tube 5, a small-diameter inner glass tube 8, an outer glass tube 10, and a solar vacuum transducer. Energy tube heat-absorbing film 9, air getter 12, pressure-bearing tube 6, heat-conducting material 7, small-diameter inner glass tube 8, outer glass tube 10 and variable-diameter curved surface transition tube 5 coated with solar vacuum energy conversion tube heat-absorbing film 9 1. Ring-shaped welding of the reduced-diameter nozzle 2, and sealing after vacuuming through the exhaust nozzle to form an annular adiabatic vacuum chamber 11. A getter mirror surface is produced by evaporation of the getter 12, so that the adiabatic vacuum chamber 11 of the solar vacuum transducer tube is highly vacuumed. . The pressure-bearing tube 6 is inserted into the cavity of the solar ...

Abstract

A solar vacuum transducing pipe with a medium conducting glass clad pipe bearing load is packaged by a outer glass pipe with diameter-changing of two glass heads necking and a small caliber inner glass pipe with transducing lamina outside. There is a glass locating nozzle for sealing and locating on mouth piece of the glass ring welding point. The glass locating nozzle connects with the large caliber outer glass pipe by welding and fuses with the inner glass pipe, which forms monolayer glass locating nozzle sealed and located by a round glass pipe. Set screw or slot for connecting with other devices on the surface of glass locating nozzle. Insert a load-bearing pipe with a sealed end into the small caliber inner glass tube. Heat-conducting medium is filled between the load-bearing pipe and inwall of the solar vacuum transducing pipe, which is sealed and connected by the closed end cap between them. Set expansion and shrinkage absorption plant on the end cap or load-bearing pipe to form through solar vacuum transducing pipe.

Description

Technical field [0001] The invention relates to a medium-conducting glass composite tube bearing pressure and directly passing through the sun vacuum transducer tube, which belongs to the field of solar energy applications. Background technique [0002] The current all-glass solar vacuum glass straight-through transducer tubes cannot withstand pressure due to structural characteristics, especially in solar energy engineering. Once a single tube bursts, the entire system will be paralyzed. The pressure-bearing operation of the system cannot be satisfied, and the solar vacuum heat collection tube can not be well applied to the solar heat collection project. Contents of the invention [0003] The purpose of the present invention is to provide a dielectric conduction glass composite tube with high safety, easy processing, high-efficiency heat collection, fast thermal start-up, and pressure-bearing operation, which is directly connected to the sun vacuum transducer tube. [00...
