Abstract
The invention relates to a method for collecting the light of the rough mirror surface of a vacuum heat-collecting pipe-cover glass pipe: a mirror-surface reflective layer with a rough surface is manufactured on the cover glass pipe; the rough surface can be obtained through acid cleaning and frosting, machine-water grinding, heat pressing and chemical processes; and the mirror-surface light-reflecting layer can be obtained through vacuum aluminum evaporation. A vacuum heat-collecting pipe manufactured according to the method is manufactured by connecting the cover glass pipe and an inner glass pipe at ports through fused sealing; and an inner glass-pipe vacuum sputtering selective absorbing film is characterized in that the mirror-surface light-reflecting layer with the rough surface within the circumference-angle range of 35-215 degrees is contained in the inner wall or the outer wall of the cover glass pipe. The invention has the beneficial effects that: the phenomenon that the sunlight originally penetrating between the cover glass pipe and the inner glass pipe to reach the smooth mirror surface of the cover glass pipe is overflowed from the other side of the cover glass pipe is changed by utilizing the mirror-surface diffuse reflection of the rough surface of the cover glass pipe. The mirror-surface light collection of the cover glass pipe is realized without an eccentric inner glass pipe or a built-in light-reflecting plate.
