Abstract
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 distribution. The FEA (Finite Element Analysis) is used to the simulation analysis, and get the temperature rises of parts and the heat fluxes of heat flowing paths. To verify the analysis and calculation results, we built the experiment model of stator. Compare the calculation results with experiment results, and we get many valuable analytical methods and designing criterions for evaporative cooling turbo generator.
