摘　　要：主氦风机驱动电机是高温气冷堆一回路中唯一的动力设备,其依靠氦气进行通风冷却.氦气在0 ～3000℃、0.1～ 10 MPa时非常接近理想气体,其定压比热容和绝热指数几乎为常数.为了研究氦气的冷却性能,以驱动电机转子端部为研究对象,建立电机端部三维物理模型;根据氦气的物理特性,计算端部的通风损耗;并基于流体力学和工程热力学原理,采用流固耦合法对转子端部温度场进行数值计算.得出靠近氦气入口端转子端部温度场分布结果,计算的结果表明,氦气在冷却方面有优势,其通风损耗小,冷却效果好,安全性高,可为以后相关的氦气冷却设计提供依据.The main helium fan＇ s driving motor is the only power equipment of the first loop of high temperature gas cooled reactor, using helium for cooling ventilation. Helium is very close to the ideal gas at 0 - 3000℃, 0. 1 - 10MPa, whose specific heat capacity at constant pressure and adiabatic index is almost constant. In order to study the cooling performance of helium; the driving motor＇ s rotor end was the research object, the 3D physical model of the motor end was built; according to the physical properties of helium, end ventilation loss for helium cooling was calculated ; numerical calculation of the rotor end＇ s temperature field was carried out with the fluid solid coupling method based on the fluid mechanics and thermodynamics principle. The temperature field distribution of the rotor end near the entrance was obtained, and the result showed that helium has certain advantages in terms of cooling because of the small ventilation loss, good cooling effect and high safety, which can provide some reference for helium cooling design related.
