Energy-saving and environmental-friendly pump-free white circulating evaporative cooling technology The Chinese Academy of Sciences Institute of Electrical Engineering has successfully developed the pump-free circulating evaporative cooling technology, which has enabled the theory and development of evaporative cooling turbine generators in China to reach the international advanced level.

China's first pump-free self-circulating evaporative cooling technology involves many disciplines such as electrical engineering and thermodynamics that belong to the cross-tech field. According to the characteristics of the hydro-generator structure, the technology utilizes a cooling medium with a suitable boiling point (about 50 degrees) and high performance, and uses a new fluorocarbon compound that does not damage the ozone layer. When the motor runs hot, it is charged and placed The coolant in the full-seal system composed of the hollow conductor and condenser of the wire rod boils due to heat absorption. The ~125-watt solar photovoltaic module was born in Shanghai Jiaotong University. The core of the solar cell with independent intellectual property rights and can produce 2 megawatts of solar cells. Equipment and production lines have also passed expert identification, while experimental production of nearly 50,000 watts of solar photovoltaic modules has been exported to Switzerland and other countries.

This solar photovoltaic cell production line is China's own national production of this production. Italy has recently developed a new type of solid thermoelectric conversion system that can be used for space power generation.

The key component of the -S* system is a new type of semiconductor material based on fir. The entire system consists of a solar pot antenna, a thermocouple coupling, a control system, and a power distribution board. It mainly uses the sun-irradiated part to self-circulate since the specific gravity of the vapor-liquid mixture is smaller than the specific gravity of the liquid and the liquid in the liquid supply tube. This continuously cools the motor while it is running.

This technology allows the hydro-generator to save material and increase efficiency. It can replace the internal cooling of water to break the capacity limit of air-cooling, improve reliability, extend the insulation life of hydro-generators, and increase the operating time by 2 to 3 times. During the operation period, it is basically in a maintenance-free state, which improves the comprehensive technical and economic indicators and provides powerful technical equipment for the localization of large-scale power station turbine generators and their participation in international competition.

The 125W solar photovoltaic cell module that has been successfully developed and produced is the largest solar photovoltaic cell module produced in China at the present time. At the same time, this production line has also been able to mass produce the same performance as the imported product, using transparent packaging materials. The crystal-guitar solar glass curtain wall made up fills the blank in China.

The difference in temperature from the shaded part produces electricity. Experiments show that when the temperature difference is between 800°C and 1000°C, the system has the highest power generation efficiency, which can reach 10 times that of traditional space power generation systems. It also has the advantages of small size, light weight, simple structure and low cost. The system can provide power for satellites and space stations as well as for ground power generation.

Gasoline Production by Gasoline The Institute of Petrochemical Synthesis of the Russian Academy of Sciences in collaboration with the Institute of Organic Chemistry has developed a gas that will make gas fields no longer burn, directly converting it into cheaper high-octane gasoline, which can avoid environmental pollution and waste. New devices that can save huge amounts of money.

This device will turn the combustion gases from the mining process into high-quality gasoline. The cost of this kind of gasoline is lower than current car fuel, and its ecological performance is even more unparalleled. In order to increase the octane number, benzene compounds are added to regular gasoline, while gasoline made of exhaust gas does not contain such harmful substances.

The key to this kind of technology for producing gasoline from exhaust gas is the use of an effective chemical additive, which can reduce the price of gasoline and improve the quality of gasoline. (CK.0123) The use of ozone to purify waste water Sakamoto Production and Quarantine has decided to use high-concentration ozone on wastewater treatment processes that use microorganisms to increase the efficiency of removing difficult-to-decompose chemicals. Ozone has a strong oxidizing power, and high concentration of ozone can decompose the chemical substances that cannot be decomposed under normal circumstances. Currently, some waste water treatment equipment in Sakamoto uses low-level ozone with a concentration of only 20x106. The new technology will increase the ozone concentration to 200x106 to increase the rate of decomposing refractory chemicals contained in the waste water and save energy.

It is believed that when ozone is combined with some chemicals, it is easy to produce new harmful chemicals. Therefore, the research project of the Ministry of International Trade and Industry will also include the implementation of safety benchmarks.
