Outline
The environmental characteristics of ultra-high altitude areas will affect the air flow and heat exchange process of the ventilation and cooling system of the generator motor, which will lead to the reduction of the cooling effect of the generator motor. In this paper, the key influencing factors of ventilation and cooling system of generator motor in ultra-high altitude environment are analyzed by mathematical model. Based on the finite element simulation, the ventilation and cooling system model of the generator motor is established and quantitatively designed considering the flow field, temperature field and conjugate heat transfer conditions. Finally, the optimal design measures of the ventilation and cooling system of the generator motor under the condition of ultra-high altitude are put forward. The research results provide a theoretical basis for the efficient and stable operation of generator motor in ultra-high altitude environment, which can effectively promotes the technological progress and development of the related industries.
