Inner evaporative cooling way of stator bars is generally affected by circulating system and coolant. In this paper, we focus those factors to improve the capability of cooling system. Based on the flowing resistance distribution of system, the structure of components is redesigned to improve the stability and reliability of circulating flow. In the same time, different kinds of coolant are used into...
when we design immersing evaporative cooling turbo generator, How to control the temperature rise of stator bars in an appropriate situation is one of the most important parts in the unit designing. In this paper, the heat flowing paths of stator components are analyzed in the immerging stator structure. Based on the heat transfer theories, Numerical simulation model is built for the stator temperature...
Evaporative cooling technique is successfully applied for large turbo generator following the air-cooled, hydrogen-cooled and water-cooled techniques. Compared with the three techniques, evaporative cooling technique absorbs the heat of thermal parts of generator by vaporization latent heat of coolant, which is sharply more efficient than the specific heat cooling approaches. The temperature rise...
Liquid cooling is an effective method to cool the rotor of turbo generator. Evaporative cooling technology is the frontier field of liquid cooling technology at present. This paper reviews fluid cooling technology for rotor of turbo generator and introduces research progress on open channel evaporative cooling technology.
