On the 20th, reporters from the Institute of Optics and Electronics, Chinese Academy of Sciences learned that with the support of the National High-tech Research and Development Program and the National Natural Science Foundation, the research team led by Rao Changhui led the team in the world for the first time to obtain high-resolution tomograms Resolution images, the future establishment of the solar atmosphere model, to achieve accurate space weather forecasting laid an important foundation for scientific research.
Solar multi-band tomography is equivalent to CT imaging of the sun by recording simultaneously images of different bands to understand the evolution of solar activity and to enable scientists to make an early warning before any harmful solar activity such as coronal mass ejection can occur. Currently, up to 6-band tomography can be achieved simultaneously in domestic and foreign solar telescopes.
Rao Chang-hui team to break through a number of key technologies, successfully developed a "7-band solar tomography system," as the world's most multi-band tomography imaging system, the detection wavelength were the corresponding sun ball, chromosphere Bottom, mid-chromosphere and chromosphere top.
The obtained solar atmosphere can be seen in the near infrared 7-band simultaneous high-resolution tomography, through the above system and the Yunnan Observatory 1-meter new vacuum solar telescope and 151-element solar adaptive optical system docked to carry out observations.
Rao Chang-hui researchers said that the instability of the solar activity on the earth will be high-voltage power transmission, oil pipelines, wireless communications and aerospace and other affected the development of these systems, the successful operation will help establish solar activity of the ball, the ball atmosphere model to achieve More accurate "solar weather forecast," and further clarify the mechanism of solar activity, providing important data support for China's space environment monitoring and space weather forecasting.
A finned tube is a heat transfer device consisting of many parallel metal fins commonly used for heat dissipation and cooling applications. Finned tubes increase the surface area of the pipe, thus increasing the heat transfer efficiency. Finned tubes are commonly used in applications such as air coolers, automotive radiators, condensers, and evaporators. They are also used in industrial heaters and refrigerators to increase heat transfer surface area and improve efficiency.
Finned tube is a kind of new, wear-resistant, efficient heat exchange material, is a kind of energy-saving heat exchange element, it uses high-frequency power source as heat source, the steel strip, steel pipe heating at the same time, so that the fusion welding together into one, with high heat exchange efficiency, large cooling area, long service life, adapt to a wide range of temperature, high pressure characteristics, it can also be made of a variety of materials, Excellent heat transfer, durability, heat resistance and corrosion resistance. Widely used in waste heat recovery, petrochemical, power plant boiler, economizer, bus, industrial and civil construction heating, refrigeration, medical drying, wood drying, food drying system and other industries.
The main business scope is various heaters, waste heat boilers, pressure vessels, supportingair preheaters, air coolers, furnace accessories and accessories, and provide equipment installation, with EPC ability of projects. At present, our customers have covered all large and medium-sized petrochemical enterprises in China and established long-term strategic cooperative partnership with them. Products are exported to Southeast Asia, Middle East, and other regions.
