The forerunner of concentrating solar power is Gilbert Cohen of the United States, which has built a large-scale concentrating solar power station in Nevada, USA, and has successfully supplied 22 megawatts of electric energy to Las Vegas.
Concentrating solar power generation, after wind energy and photovoltaic cells, has begun to emerge, and is expected to become an effective technical means to solve energy shortages and cope with climate warming.
Basic principle: concentrating solar power uses a parabolic mirror to concentrate the light onto a heat-absorbing tube filled with synthetic oil, and then delivers the synthetic oil heated to about 400 degrees Celsius to the heat exchanger, and the heat is passed through the heating circulating water. Water is heated to generate water vapor, which drives the turbine to turn the generator to generate electricity.
Concentrating solar power is different from solar cells. Solar cells use solar panels to convert solar energy directly into electricity. They can be operated on cloudy days. CSPs can only be used in sunny and sunny places.
However, even in the absence of the sun, the use of molten salt to store heat can now solve the problem of all-weather power supply.
The predictions of the International Energy Agency (IEA) SolarPACES, the European Solar Thermal Power Generation Association (ESTELA) and Greenpeace are more moderate, and CSP will account for 3%-3.6% of global energy supply by 2030, by 2050. It accounts for 8%-11.8%, which means that by 2050, CSP installed capacity will reach 830GW, adding 41GW per year. In the next 5-10 years, the cumulative annual growth rate will reach 17%-27%.
Compression injection molding: it is an advanced form of traditional injection molding.Advantages: it can increase the flow length ratio of injection molded parts; Adopt less clamping force and injection pressure; Reduce the internal stress of materials; And improve processing productivity.Injection compression molding is applicable to products made of various thermoplastic engineering plastics, such as large-size curved parts, thin-walled parts, miniaturized parts, optical lenses, and parts with good impact resistance requirements.
Low pressure injection molding:Low pressure injection molding process is a packaging process that uses very
low injection pressure to inject hot-melt materials into the mold and solidify rapidly. With the excellent sealing performance and excellent physical and chemical properties of hot-melt materials, it can achieve the effects of insulation, temperature resistance, impact resistance, vibration damping, moisture-proof, waterproof, dustproof and chemical corrosion resistance, and play a good role in protecting electronic components.
