| 抄録(英) | We are developing a coil immersion oil-cooled structure to improve e-Axle power density. In this report, we have investigated the effect of the cooling performance improvement by testing a prototype machine. As a result, the following conclusions were obtained. In oil-immersed cooling, the distance between coils can maintain high continuous performance by considering the flow rate of the cooling oil between the coils and the effect of copper loss in the indirect water cooling structure, it was confirmed that the temperature difference from upstream to downstream is small, but in the oil-immersed cooling structure, there is a temperature difference of about 10K between upstream and downstream, and the maximum temperature that determines the continuous torque occurs downstream. In the oil-immersed cooling structure, the sensitivity of the coil temperature to the amount of cooling oil is low upstream and high downstream. In this oil-immersed cooling structure, it was confirmed that the continuous operation area for the maximum torque is about 60%. 翻訳 |
