摘要:
 摘要:为研究径向通风电机内部流体分布、传热性能及温升特性,根据径向通风电机通风结构及传热特点,建立三维流动及传热耦合的物理模型和数学模型,结合工程实际给出基本假设和边界条件,采用有限体积法对流体场及温度场进行求解,得出电机内部冷却介质流动性能、传热特性及电机各部件的温升分布情况。最后,对电机定转子股线、绝缘及铁心温升分布做了详细分析,获得电机温升分布趋势及温升最大值的位置。为径向通风电机综合物理场的准确计算以及通风结构的优化提供了理论依据。
Abstract:
 Abstract:In order to study distribution of fluid flow, the characteristic of heat transfer,and temperature rise characteristics of radial ventilation generator,a mathematical and physical model of 3D fluid flow and heat transfer coupled was established according to structure characteristic of radial ventilation generatorFlow fluid and field was calculated coupled using finite volume method by giving fundamental assumptions and corresponding boundary conditionsFrom the research,the performance of fluid flow characteristic of heat transfer,and temperature rise distribution of generator were obtainedFinally,the temperature rise distribution of the strand, insulation and iron core of stator and rotor are analyzed respectively, the maximum temperature rise position of each parts of the motor are obtainedThe theory gist for accurate calculation of synthetic physical fields and structure optimization for the radial ventilation generator is provided
