摘要
运用稳定导热问题的有限差分法分析电机三维温度场,对电机内的对流换热系数采用h= c v~n的计算公式,引入气体热流的概念,对电机温度场与电机内空气温度场使用耦合边界条件,实现了两者的同时迭代求解。
Calculating the convective heat transfer coefficient by the formula h = c v^n and defining the air thermal current conception, this paper analyze the 3D temperature field of the electric motor by finite difference method bough the integral conduction equation, and solves the temperature field in the electric motor and the air temperature field through iterative method by using the coupled boundary condition.
