| 在“节能与新能源汽车技术路线图2.0”中明确了电机功率密度和效率的要求，随着电机功率密度要求的提升意味着对于电机散热需求的加大，当前水冷技术难以满足要求，由此需要对电机油冷技术进行深入研究。基于发电机，从电机损耗分布和热传导路径出发，通过油冷台架快速验证研究冷却设计参数对于电机散热的影响，选择最优的冷却设计方案，同时为热网络法和有限元法仿真提供数据参数，最终通过油冷电机的温度场试验验证了油冷设计在电机上的散热效果，并与仿真数据进行对比研究热网络法和有限元法的准确性，同时通过在当前冷却结构下不同持续输出功率的温升情况，确定该电机油冷设计的优化潜力，从最终结果上看出优化后的油冷设计使得持续功率达到了40kW相比于项目目标提升33.3%，在该油冷结构设计下其额定工况最大可满足电流密度15A/〖mm〗^2下的散热要求。 |

| In "Energy saving and new energy Vehicle Technology Roadmap 2.0", the requirements of motor power density and efficiency are clearly defined. With the increase of motor power density requirements, the demand for motor heat dissipation is increasing. The current water cooling technology is difficult to meet the requirements, so it is necessary to conduct in-depth research on motor oil cooling technology. Based on the generator, starting from motor loss distribution and heat conduction path, through the oil cooling platform quickly validation to study the effect of cooling design parameters for motor cooling, choose the optimal design of cooling, at the same time to provide data for thermal network and finite element method simulation parameters, eventually passed the test of the temperature field of oil cooled motor oil cooling design was verified on the motor cooling effect, And compared with simulation data to study the accuracy of the thermal network and finite element method, and at the same time through the current cooling structure of continuous output power under different temperature conditions, determine the optimized potential oil cooling design, seen from the final result the optimized oil cooling design makes continuous output reached 40 kw up 33.3% compared with the project goals and Under the oil-cooled structure design, its rated operating condition can meet the heat dissipation requirement at current density of 15A/〖mm〗^2. |
