1. A power generation module comprising:
an electric motor including a stator, a rotor, and a motor housing that receives the stator and the rotor, the motor housing having first and second end portions between which the motor housing extends in a longitudinal direction;
an inverter including a capacitor, an insulated-gate bipolar transistor (IGBT), bus bars, and an inverter housing that receives the capacitor, the IGBT, and the bus bars;
a cooling water flow path defined at the motor housing to allow cooling water to flow therethrough;
a first oil flow path defined at the first end portion of the motor housing and extending along a circumferential direction of the motor housing;
a plurality of first injection nozzles spaced apart from one another along the first oil flow path and configured to spray oil from the first oil flow path toward an inner space of the motor housing;
an oil injection housing mounted to the second end portion of the motor housing;
a second oil flow path defined at the oil injection housing along the circumferential direction; and
a plurality of second injection nozzles spaced apart from one another along the second oil flow path and configured to spray the oil from the second oil flow path toward the inner space of the motor housing.
