Embodiment Construction

[0051] Such as figure 1 , figure 2 , image 3 Shown: a pressure-sealed shrink-mouth variable-diameter flat tube heat collection all-glass vacuum photovoltaic power generation heat-collecting tube is compressed and sealed to a rectangular flat glass tube 3 by shrinking the mouth of the outer cover glass tube and reducing the diameter, forming a pressure-sealed tube mouth 1 of the heat-collecting tube, and photovoltaic power generation The battery 9, the exhaust nozzle 6 and the air getter 7 form a heat-collecting all-glass vacuum photovoltaic power generation heat-collecting tube with a compression-sealed shrink-mouth variable-diameter flat tube. One side of the outer wall surface of the rectangular flat glass tube 3 is compounded with a photovoltaic cell 9, and the interlayer of the outer cover glass tube 2 and the rectangular flat glass tube 3 is vacuumed through the exhaust nozzle 6 to form a vacuum insulation interlayer 4, and a vacuum insulation interlayer 4 is installed...

Abstract

A press sealed necking reducing flat tube heat collection all-glass evacuated photovoltaic collector tube comprises a cover glass tube, a rectangular planar glass collector tube, a support elastic card of a getter and an exhaust nozzle; the base tube of the rectangular planar glass collector tube of the invention is a rectangular glass tube; tube heads at both ends of the rectangular glass tube are processed into round glass tube heads; the surface of the outer wall of the manufactured rectangular glass tube with openings at both ends is compounded with a photovoltaic cell; the tube heads at both ends of the cover glass tube are uniformed and sintered; by annular reducing, pressing, soldering and sealing by glass, the cover glass tube mouth is necked and sealed with the mouth of the rectangular planar round glass collector tube to form a single-layer glass round tube mouth; after the interlayer of internal and external glass tubes is vacuumized, the exhaust nozzle is sealed by glass and the getter is evaporated to manufacture the press sealed necking reducing flat tube heat collection all-glass evacuated photovoltaic collector tube. The tube can be used for power generation, enjoys high heat absorption efficiency and long service life and can utilize scattered light.

Description

technical field [0001] The invention relates to a solar heat collection tube, in particular to a heat-collecting all-glass vacuum photovoltaic power generation heat-collection tube of a highly efficient compression-sealed shrink-mouth variable-diameter flat tube, which belongs to the field of solar energy applications. Background technique [0002] At present, the known solar energy all-glass vacuum heat collecting tube is an outer circular cover tube with an inner circular heat collecting tube structure. This structure has serious heat radiation and heat dissipation, poor thermal insulation performance, and prevents scattered light from entering, so it cannot generate electricity. Contents of the invention [0003] In order to solve the above-mentioned problems, a heat-collecting all-glass vacuum photovoltaic power generation heat-collecting tube with a compression-sealed shrink-mouth variable-diameter flat tube is invented. The invention not only has high heat absorption ...
