Electrostatic anti-scaling full glass vacuum photovoltaic generating heat collection tube with fluid director

Abstract

The invention discloses an electrostatic anti-scaling full glass vacuum photovoltaic generating heat collection tube with a fluid director, which comprises an outer cover glass tube, a semicircular planar heat collection glass tube, a getter supporting-fixing elastic clamp, an exhaust nozzle, a photovoltaic cell layer connecting electrode, the fluid director, a conductive film layer, an electric insulating layer and a conductive film layer connecting electrode. A base tube of the semicircular planar heat collection glass tube is a semicircular glass tube, two tube ends of the semicircular glass tube are processed into circular glass tube ends, one end of the semicircular glass tube is opened, and the outer wall surface of the semicircular glass tube is compounded with a photovoltaic cell.The two tube ends of the outer cover glass tube are flushed to a burner nozzle, and an electric conductor connected to the photovoltaic cell of the circular glass tube is led out through a glass sealing electrode. The electric conductor connected to the photovoltaic cell is led out through the glass sealing electrode. An annular reducing pressing glass is welded and sealed, the reducing port of the outer cover glass tube orifice is sealed with the semicircular planar heat collection glass tube orifice, sandwich layers of internal and external glass tubes are vacuumized, then the exhaust nozzle is sealed, and the getter is evaporated. The electrostatic anti-scaling full glass vacuum photovoltaic generating heat collection tube has the advantages of high efficiency, long service life and scale prevention, and can use scattered light.

Description

technical field [0001] The invention relates to a solar heat collection tube, in particular to a high-efficiency electrostatic anti-scaling all-glass vacuum photovoltaic power generation heat collection tube provided with a deflector, which belongs to the field of solar energy applications.
