Abstract :
Various cooling systems for High Temperature Superconducting (HTS) synchronous machines were analysed and discussed in this paper. Thermosyphon cooling has been applied in several demonstration HTS synchronous machines. The heat transfer characteristics of this method and the temperature field of rotor were investigated in details. Furthermore, open evaporative cooling and piping evaporative cooling were originally pointed out for HTS machines with different rotate speed ranges. The simulated results showed that open evaporative cooling can acquire more uniform temperature distribution of HTS windings. Piping evaporative cooling is preferred for cooling rotor of low rotate speed HTS machines. Based on above analysis, an integrated rotor cooling platform has been designed to investigate the characteristics of different cooling systems.
