Academician Gu Guobiao: evaporate and cooling technology, providing technical support for energy consumption issues for big data development

Gu Guobiao, an academician of the Chinese Academy of Engineering, the first batch of experts and members of the review committee of China Science and Technology Think Tank, and an expert in electrical engineering. Researchers, doctoral supervisors of the Institute of Electrical Engineering of the Chinese Academy of Sciences, and director of the new technology laboratory of electricity and equipment.

Gu Guobiao has long been engaged in the research and industrialization of large -scale motor evaporation and cooling technology. Applying normal temperature -free pump self -circulating and cooling technology to industrial units, forming a new type of motor cooling technology with independent intellectual property rights. Expand the evaporation cooling technology to the fields of electrical and electronic information equipment such as wind power generator, super computer, promoting motor and inverter, and expand the content of related disciplines such as electricals, electrical appliances and heat workers, and form the evaporation and cooling technology of electrical equipment. Cross -disciplinary direction.

R & D original cooling technology

In 1958, Gu Guobiao led the team to develop a 15 -kilowatt -low -temperature evaporation cooling motor, which proved the feasibility of evaporating cooling technology for large motor equipment. Gu Guobiao introduced that a large amount of heat generates a large amount of calories when running and cooling. Internationally, there are two types of cooling methods: air -cooled and water -cooled, while evaporation and cooling technology uses low -boiling liquids to convey heat through phase change heat to achieve cooling, to achieve cooling of power generation equipment, and there is no safety problem. This economy -efficient new cooling technology is an original technology we proposed and realized.

Gu Guobiao's biggest dream is to apply evaporation and cooling technology in the Three Gorges Project. He led the team to study hard. In December 2011, the first 700,000 kilowatt -cooler cooling water wheel generator was successfully operated at the Three Gorges Power Station. This is the world's most capacity evaporation and cooling generator set. It uses my country's "stator winding self -circulating constant temperature evaporation and cooling technology" with completely independent intellectual property rights. At present, two of the 32 generator sets installed in the Sanxia Hydropower Station have used Guo Guobiao's evaporation and cooling technology. Regardless of the equipment capacity and technical indicators, the two 700,000 kilowatts of evaporation of the cooling water wheel generator have reached the international leading level. And its performance is stable and economical, which greatly extends the service life of the motor.

Gu Guobiao said that the development and application of big data are becoming more and more important, and there are massive data generation every day. This requires more data centers, more servers and more computer rooms. At present, the large data storage volume is large, and the power consumption of the server is a major problem facing the development. The energy consumption constraint problem provides technical support. Applying evaporation and cooling technology in the computer field is superior to traditional water -cooled, air -conditioning cooling. He said that in the future, evaporation and cooling technology will also be useful in the aspects of new energy power distribution and pumping energy.

Give more time for independent innovation

Gu Guobiao said that we must establish the self -confidence of independent research and development and innovation, and we must not always "cottage." Before the application of evaporation and cooling technology industry, the field of large -scale water conservancy engineering power equipment in my country adopted foreign technology. Gu Guobiao said that I have to do one or two things that are not foreign countries, or they cannot do what foreigners cannot do. As a result, Gu Guobiao led the team to complete the development of a series of evaporate cooling water rotor generators. In 1992, Ankang's 50,000 kilowatt -kick -evaporating cooling water wheel generator was successful. Run; in 2011, combined with rare earth permanent magnet technology and evaporation cooling technology, the 3.6MW evaporating cooling permanent magnet half -direct drive wind power generator was developed; in 2013, the high -power water wheel generator crew of the Three Gorges passed the acceptance.

Gu Guobiao said that the current evaporation and cooling technology we study is completely independent of innovation without any traces of foreign countries. He pointed out that the current industrialization faces great innovation space facing traditional technologies to high reliability and recycling of recycling, low -end technology to high -tech development and new technologies towards high -efficiency and low maintenance directions. There are two types of innovation, one is theoretical innovation, and the other is technological innovation. He hopes that my country's entrepreneurial teams can emerge a group of experts with comprehensive innovation capabilities, and they can overcome technical difficulties. They have both theories and practice.

At the same time, Gu Guobiao believes that all sectors of society need to include and understand independent innovation technologies. The technology of independent innovation must go through one after another to go up, and it should be given more time for independent innovation. He said that the current system of independent innovation in China needs to be further improved. The country lacks mechanisms to use the environment for the first set of innovative equipment. From scientific research institutions to enterprises, they have not provided a tolerance environment for technical products independently developed by our country, and they did not give it support, encouragement and confidence.

In terms of cultivating talents, Academician Gu pointed out that practicing the truth and practicing talents. Cultivating talents need to have the right understanding. The purpose is to continuously launch new technologies, new processes and new designs, and educational methods must be continuously updated. You cannot just write a dissertation and experiment. You must return to the actual production work, and you must fight, explore, and summarize the laws. (Text/Wang Huilan)
