Evaluation of Water Cooling System of 1.5MW Rotor Based on CFD

Abstract:

The water cooling system of 1.5MW rotor is evaluated using Computational Fluid Dynamics (CFD). 48 cooling holes are opened on the rotor stator to arrange the water cooling pipes, the temperature of inlet of the cooling water is 50 C with the velocity 1.2m/s. It is found that the air gap between the cooling pipes and holes on the stator hinders the heat exchange extensively. For this reason, the cooling system can't meet the design requirement. In order to solve this problem, the pourable silicone is filled in the gap between the cooling pipes and holes to enhance thermal conductivity. Based on this idea, ten kinds of piping arrangements are proposed, among which, nine kinds can achieve the cooling requirement.
