Overheat Analysis and Solution for the Engine on a Certain Moving Power Station

为了解决某电源车发动机过热问题,从优化空间布置的角度出发,综合考虑散热部件结构对系统阻力和风量的影响,通过整体结构优化、一体式焊接、气侧通道结构优化等降低系统阻力的措施,提出了对冷却系统进行改进的解决方案,改进后的散热器的整体厚度变小.经过试验,发动机过热问题得到了解决并实现了210k W电力功率的输出,比设计要求值提高了5%,说明解决方案有效.

In order to solve the problem of engine overheating for a certain moving power station, in this paper a solution was proposed to improve the sooling system by considering the effect of the structure of the heat sink on the resistance and air flow of the system from the angle of optimizing the space layout, the integral structure optimization, integral welding, air side channel structure optimization and other measures to reduce the resistance of the system, and after the amelioration the overall thickness of the radiator was reduced. The experiment results showed that the engine overheating problem is solved; the output of 210kW electric power is achieved, and outperforms the design rgquirement by 5%. It is concluted that the proposed solution is feasble and effective.
