Abstract

The present invention relates to an intelligent power generation module comprising: an electric motor having a motor housing forming the exterior thereof; an inverter formed at one side of the motor housing and having an inverter housing in which an IGBT and a capacitor are received; an inner housing disposed inside the motor housing and receiving a stator and a rotor therein; and a dual flow channel disposed on the same circumferential surface of the inner housing, wherein the dual flow channel comprises: multiple first cooling flow channels which are spaced apart from each other in the longitudinal direction of the inner housing and through which a first cooling fluid flows; a second cooling flow channel which is formed between the respective multiple first cooling flow channels and through which a second cooling fluid flows; and multiple injection nozzles which are disposed in each of the multiple first cooling flow channels while being spaced apart from each other in the circumferential direction and through which the first cooling fluid is injected into the inner space of the inner housing.

Description

technical field [0001] The invention relates to an intelligent power generating module with a motor cooling structure in an oil-water cooling composite mode. Background technique [0002] Recently, electric vehicles (including hybrid vehicles) that use an electric motor as a driving source for vehicle travel are being marketed as future vehicles because of their excellent fuel ratio. [0003] Generally, an IPGM (Intelligent Power Generation Module: Intelligent Power Generation Module) is a device composed of a motor, an inverter, and a gear box. [0004] The motor has a rotor and a stator, and the rotor may be rotatably provided inside the stator. [0005] The stator has a stator coil wound around a stator core, and when a current is applied to the stator coil to rotate the rotor, heat is generated in the stator coil, and technologies for cooling the heat generated in the motor are being developed. [0006] In the case of an electric motor of an electric vehicle, cooling h...
