Example Embodiment

[0014] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0015] Such as figure 1 As shown, the photoelectric light-heat combined vacuum straight-through collector tube used in the trough-type concentrating system of the present invention includes a vacuum tube 2, the outer tube 1 of the vacuum tube 2 is a glass cover tube, and the inner tube 3 of the vacuum tube 1 is A copper tube. The diameter of the inner tube 1 is determined by the actual situation. During use, it is only necessary to control the flow of water according to the temperature of the circulating water. The two ends of the copper tube and the glass cover tube are sealed by metal sealing technology. The outer turning surface of the copper tube 3 is divided into the first surface (half the circumference of the copper tube) and the second surface by the axial symmetry plane as the boundary (The other half of the circumference of the copper tube)...

Abstract

The invention discloses a photoelectric photo-thermal combined vacuum straight-through heat collector for a trench light condensing system. A selective absorption coating is coated on a half cycle of an inner copper pipe of a straight-through pipe, a battery plate is attached to the other half cycle, and the inner and outer pipes are vacuumized, so that heat loss in the pipe due to heat conduction and convection heat transfer is reduced. In a light condensing photovoltaic generating system, one side attached with the battery plate can receive focused light to generate electricity, and one side coated with the selective coating can absorb shielded direct solar energy to reduce the surface temperature of the battery plate through water circulation in the copper pipe; and the generated hot water can be stored in a water tank to be used as domestic hot water. The heat collector has the advantages of simple structure, low production cost, high overall efficiency and the like, and can be widely applied to the light condensing photovoltaic generating system.

Description

technical field [0001] The invention relates to a heat collecting tube, in particular to a heat collecting tube capable of generating electricity and hot water, which is applied in a currently researched solar focused photovoltaic power generation system. Background technique [0002] As the world's energy crisis is getting worse, people are forced to pay more attention to the use of solar energy. Many countries have invested a lot of material and manpower in the research and development of solar power generation technology, especially solar photovoltaic power generation. In recent years, my country is also vigorously researching, developing, promoting and applying solar photovoltaic power generation. In photovoltaic power generation, concentrating photovoltaic is characterized by less pollution, less energy consumption, and high conversion efficiency, and can use relatively cheap concentrators. In recent years, this power generation technology has attracted more and more att...
