Problems solved by technology
The all-glass vacuum heat collecting tube with built-in metal heat pipe has the defects of high production cost, fouling at the exothermic end, and low efficiency
The glass heat pipe with liquid heat transfer medium inside the all-glass vacuum heat collector has the defects of high production cost, fouling at the exothermic end, slow thermal start, low efficiency, and poor safety.
Metal heat collector plate heat pipe vacuum heat collector has defects such as high production cost, fouling at the exothermic end, difficulty in maintaining vacuum degree, and difficult processing technology.
Double-vacuum all-glass heat-pipe heat collectors have defects such as poor safety, low efficiency, and fouling at the exothermic end. Single-pass glass-metal heat collectors are difficult to maintain vacuum and have serious fouling

A single-way reducing glass solar vacuum heat-collection tube is glass casing tube with one open end. A metal support card is used to support positioning by external glass and to form one - way reducing and double layer glass casing tube with one end being closed and another end being opened; setting reflection and focus mirror on outer glass tube for reflecting light to inner glass tube with energy conversion film board and blocking air cartridge container on outer tube wall with tip seal after jacket layer is vacuumed.
Description
technical field [0001] The invention relates to a single-pass variable-diameter glass solar vacuum heat-collecting tube provided with a reflecting and concentrating mirror surface, which belongs to the field of solar energy applications. Background technique [0002] At present, there are six kinds of solar vacuum heat collecting tubes, the first is all glass vacuum heat collecting tube, the second is all glass vacuum heat collecting tube with metal heat pipe inside, and the third is glass heat pipe all glass with liquid heat transfer medium inside. Vacuum heat collecting tube, the fourth type is metal heat collecting plate heat pipe vacuum heat collecting tube, the fifth type is double vacuum all-glass heat pipe heat collecting tube, and the sixth type is single-pass glass metal heat collecting tube. [0003] All-glass vacuum heat collectors have defects such as scaling, freezing cracks, and slow thermal startup. The all-glass vacuum heat collecting tube with built-in meta...
