Zusammenfassung:The present invention relates to a cooling module for an electric vehicle motor. The turbulent cooling module for an electric vehicle motor provided by the present invention includes: a water jacket which is formed in a cylindrical shape to accommodate a rotor inside; a case which has an inner circumference surface separated from an outer circumference surface and forms a space between the water jacket and the case by being arranged to surround the water jacket; a front cover which has a plurality of turbulent nozzles enabling cooling water to generate turbulence and flow into a space and finishes the front side of the case; and a rear cover which discharges cooling water flowing to the space and finishes the rear side of the case. The present invention has advantages of: increasing heat transfer efficiency of cooling water by enabling cooling water flowing to the upper part of the motor to generate turbulence; and having a cooling effect throughout the motor by lowering the temperature of cooling water by passing the cooling water through orifice. 본 발명은 전기자동차 모터용 냉각모듈에 관한 것으로, 내측으로 로터가 수용되도록 원통형으로 형성된 워터자켓; 내주면이 상기 워터자켓의 외주면과 이격되고, 상기 워터자켓을 감싸도록 배치되어 상기 워터자켓과의 사이에 공간을 형성하는 케이스; 냉각수가 난류를 일으키며 상기 공간으로 유입되도록 하는 복수의 난류노즐을 구비하고, 상기 케이스의 전방을 마감하는 프론트커버; 및 상기 공간으로 유입된 냉각수를 배출시키며, 상기 케이스의 후방을 마감하는 리어커버;를 포함하는 것을 특징으로 하는 전기자동차 모터용 난류 냉각모듈을 제공한다. 이러한 본 발명은 모터 상부로 유입되는 냉각수가 난류를 생성하도록 하여 냉각수의 열전달 효율을 상승시키고, 냉각수가 오리피스를 통과하도록 함으로써 냉각수의 온도를 낮추어 모터 전반에 걸쳐 냉각효과가 나타날 수 있도록 하는 장점이 있다.
