Solar vacuum tranducing tube having photo-heat conversion film compounded on pressure-bearing straight-through tube

Abstract

A solar vacuum transducing pipe with its load-bearing pipe combining an optical-thermal transition film is packaged of a small caliber inner glass pipe with one end welding seal and transducing lamina outside and a large caliber outer glass pipe with a blast pipe hush on welding head. The end is sealed by ring welding to form a solar vacuum transducing pipe with two ends through. 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. The load-bearing through endothermal pipe set into the small caliber inner glass pipe is single pipe or combined with fin. The load-bearing through endothermal pipe combines optical-thermal transition film and is sealed and connected with glass locating nozzle by the closed end cap. Set expansion and shrinkage absorption plant on the end cap or load-bearing pipe.

Description

Technical field [0001] The invention relates to a solar vacuum transducer tube with a light-to-heat conversion film compounded on a pressure-bearing straight-through tube, belonging 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 transducer tube cannot be well applied to solar heat collection projects. Contents of the invention [0003] The purpose of the present invention is to provide a solar vacuum transducer tube with high safety, easy processing, efficient heat collection, fast thermal start-up speed and pressure-bearing straight-through tube compounded with a light-to-heat conversion film. [0004] The object of the pres...
