Abstract
In order to make sure that the evaporative cooling method has the same cooling effect with the inner water cooling, in this paper, we compared this two cooling modes through analysis method and numerical calculation method respectively. The results show the evaporative cooling has almost the same cooling effect with the inner water cooling method. At the same time, the evaporative cooling system has more even temperature distribution along the circumferential direction.
