Abstract

The invention relates to medium-high-temperature solar vacuum heat collecting tube glass end cap packing structure and manufacture technique. The invention primarily solves the problem that the high external heat loss and complicate packing technique of the sealing terminal of the high temperature metal flow passage solar vacuum heat collecting tube under high pressure and high temperature condition, to provide new technical method to produce solar medium-high-temperature heat collecting tube. The glass end cap packing structure is composed by glass caps with different structure and relative nickel iron alloy strike component. The glass end cap component produced by The invention is useful to improving the mechanical connecting intensity of the glass metal solar vacuum heat collecting tube, to reduce the heat loss caused by heat radiating, heat convection, and heat conducting, to improve the stability of the vacuum heat collecting, it is useful to realizing specialized production.
