摘要

由于汽车行业的电气化驱动，热管理对于提高电机的功率密度和连续运行限制至关重要。需要更先进的主动冷却，直接油喷雾冷却方法是一个有吸引力的解决方案，因为它可以提供有效的对流传热。然而，提供如何将油喷雾冷却应用于发夹绕组定子的实用指南的技术文献是有限的。本文介绍了采用不同喷嘴进行径向油喷雾冷却的实验特性。通过对试验数据的分析，探讨了喷嘴速度对末端绕组温度变化的影响。

EXPERIMENTAL CHARACTERISATION OF RADIAL OIL SPRAY COOLING ON A STATOR WITH HAIRPIN WINDINGS

Thermal management is critical to increase the power density and the continuous operating limit of electric motors due to the drive for electrification of the automotive industry. A more advanced active cooling is required and direct oil spray cooling method is an attractive solution because it can give effective convective heat transfer. However, the technical literature providing practical guidelines of how oil spray cooling should be applied to stator with hairpin winding is limited. This paper presents the experimental characterisation of radial oil spray cooling by using different spray nozzles. The test data is analysed to investigate the impact of nozzle velocity on the temperature variation of the end windings.
