Solar vacuum transducing tube having photo-heat conversion film compouned on pressure-bearing 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. 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 endothermal end of load-bearing pipe set into the small caliber inner glass pipe is single pipe or combined with fin. The endothermal end of load-bearing pipe combines optical-thermal transition film and is filled with phase-changing medium, which is sealed and connected with glass locating nozzle by the closed end cap between the glass locating nozzle of solar vacuum transducing heat pipe and the load-bearing pipe.

Description

Technical field [0001] The invention relates to a solar vacuum heat exchange heat pipe compounded with a light-to-heat conversion film on a pressure-bearing tube, which belongs to the field of solar energy applications Background technique [0002] The current all-glass solar vacuum heat exchange heat pipes cannot withstand pressure due to structural characteristics, especially in solar engineering, once a single pipe bursts, the entire system will be paralyzed. The pressure-bearing operation of the system cannot be satisfied, and the solar vacuum heat exchange heat pipe cannot be well applied to solar heat collection projects. Contents of the invention [0003] The object of the present invention is to provide a solar vacuum energy-transfer heat pipe compounded with a light-to-heat conversion film on the pressure-bearing tube with high safety, easy processing, high-efficiency heat collection, fast heat start-up, and pressure-bearing operation. [0004] The object of the ...
