  • Patent number: 11214240
    Abstract: An electric oil pump system allows the cooling of an electric oil pump (EOP) and an oil pump controller (OPU) to be performed efficiently in the vehicle equipped with the electric oil pump. An electric oil pump of the system includes a pumping part that is operated by power of a motor to suction and direct pressurized oil. An oil pump controller operates the electric oil pump. A water-cooled cooling apparatus cools the oil pump controller using coolant and an oil-cooled cooling apparatus cools the electric oil pump using oil. The coolant of the water-cooled cooling apparatus and the oil of the oil-cooled cooling apparatus pass through a heat exchanger and as the coolant and oil pass therethrough, heat exchange is achieved.
