GU GUOBIAO Gu Guobiao, the electrical specialist, was born in June of 1936 in Shanghai. He graduated from the Department of Electrical Engineering of Tsinghua University in 1958. After graduation, He worked in the Institute of Electrical Engineering, Chinese Academy of Sciences till now. He was appointed as the departmental director in 1984 and Professor in 1987, now he is the director of the degree assessment committee and PhD Candidates Supervisor in the Institute of Electrical Engineering, the director of New Electrical Research Department and the principal of evaporative cooling technology research center, he was elected as an academician of the Chinese Academy of Engineering in 1997. Prof. Gu has been engaging in the development of the new evaporative cooling technology of large generator for a long term. The evaporative cooling technology in normal temperature (60 ℃ about) was independently innovated and the selfcirculating evaporative cooling system without pump has been applied in hydrogenerators. He has researched the heat transfer characteristics of all kinds of coolant in the condition of twophase boiling、the physical and chemical characteristic and electric insulation characteristic. He has combined the subject of generator with that of the heat transfer in boiling twophase fluid and a crosssubject design theory system has been shaped. Cooperated with the manufactural enterprises, the industrial pattern machines of 10MW (1983) and 50MW (1992) have been developed. In the end of 1999, 400MW (400 thousand kilowatt), known as the largest hydrogenerator in China at that time was successfully developed. The evaporative cooling systems of those machines have been safely working for a long time and made a no accident operating record in the inner cooling system of the generator. It becomes an example of independent innovation of the key technology of large equipments. The evaporative cooling technology was regarded as the one of four new evolutions on rotating power machine field by CIGRE held in France in 2000. Now huge units using evaporative cooling technology are developed for improving the ability of making important power device and the technology is also extend to apply to other electrical devices.  Prof.Gu is the awardee of the following prizes and awards: an award from National Science and Technology Conference (in 1978), two 2ndClass Prize of National Science and Technology Progress Award (in 1988 and 2002), two 1stClass Prize of CAS Science and Technology Progress Award (1987 and 2000). Besides, Prof.Gu published over seventy papers and presented five reports on international conferences.
