Electrostatic antiscale all-glass evacuated photovoltaic collector tube

Abstract

An electrostatic antiscale all-glass evacuated photovoltaic collector tube comprises a cover glass tube, a semi-round planar glass collector tube, a support fixed elastic card of a getter and an exhaust nozzle; the base tube of the semi-round planar glass collector tube of the invention is a semi-round glass tube; tube heads at both ends of the semi-round glass tube are processed into round glasstube heads; the surface of the outer wall of the manufactured semi-round glass tube with openings at both ends is compounded with a photovoltaic cell layer; an electric conductor is connected on the photovoltaic cell layer and is led out via an electrode sealed and sintered by glass; 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 semi-round planar round glass collector tube as a whole 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 electrostatic antiscale all-glass evacuated photovoltaic collector tube. The tube enjoys high heat absorption efficiency, good antiscale property and long service life and can utilize scattered light.

Description

technical field [0001] The invention relates to a solar heat collecting tube, in particular to a high-efficiency electrostatic anti-scaling all-glass vacuum photovoltaic power generation heat collecting tube, which belongs to the field of solar energy applications. Background technique [0002] At present, the known solar energy all-glass vacuum heat collection tube is an outer circular cover tube with an inner circular heat collection tube structure. This structure has serious heat radiation and heat dissipation, poor thermal insulation performance, serious scaling inside the tube, and blocks the entrance of scattered light. In order to solve the above problems, an electrostatic anti-scaling all-glass vacuum photovoltaic power generation heat collector was invented. This invention not only has high heat absorption efficiency, good heat preservation performance, no scale in the tube, but also can reduce heat radiation, use scattered light, and reduce production cost.
