Photovoltaic and photothermal coupling complementary integrated utilization system

Abstract

The invention provides a photovoltaic and photothermal coupling complementary integrated utilization system, which comprises a condensation system, a plurality of vacuum tubes, a water storage unit and a storage battery. Each vacuum tube comprises a glass outer tube, a glass inner tube, a first solar cell panel pasted to the outer wall of the glass inner tube, an arc-shaped glass partition plate arranged in the glass inner tube, a second solar cell panel pasted to the arc-shaped glass partition plate, and a sealing cover for sealing the glass inner tube, wherein the glass outer tube and the glass inner tube are coaxially arranged; closed circulating fluid channels are formed between the sealing covers and the arc-shaped glass partition plates as well as between the sealing covers and the inner walls of the glass inner tubes, filled with nano-fluids and provided with miniature pumps; thermal diodes are arranged at the front ends of the vacuum tubes, one ends of the thermal diodes extendinto the fluid channels, and the other ends of the thermal diodes extend into the water storage unit; and the storage battery is electrically connected with the first solar cell panels and the secondsolar cell panels. The solar energy utilization rate can be increased, and high-quality thermal energy is output.

Description

technical field [0001] The invention relates to the field of solar energy applications, in particular to a photovoltaic light-thermal coupling complementary integrated utilization system. Background technique [0002] With the increasingly prominent issue of energy saving and carbon reduction, the exploration of new clean energy has become a boom all over the world. Among the clean and renewable energy sources, solar energy is becoming more and more popular among scientific and technological workers due to its abundant reserves, cleanness, safety, and wide distribution. According to statistics, the energy of solar radiation reaching the earth's surface is as high as 4×10 15 MW, about 2000 times the global energy consumption. my country has abundant solar energy resources. If the solar energy can be used reasonably, it will undoubtedly have an important impact on the environmental pollution and energy shortage problems faced by my country's economic development.

Problems solved by technology

In the existing photovoltaic photothermal integrated utilization system, since the solar panel in the vacuum tube cannot transfer heat to the heat transfer medium in time, the photoelectric conversion efficiency of solar energy is low, and the problem of outputting low-quality heat makes the hot water supplied lower temperature
