The present invention relates to an oil flow path-mounted cooling apparatus in a motor housing of an electric vehicle. The oil flow path-mounted cooling apparatus in a motor housing of an electric vehicle comprises: a heat pipe engaged with an oil flow path of the motor housing of the electric vehicle, and extended to the outside of the motor housing, and moving the heat generated in the oil flow path to the outside of the motor housing; and a heat radiation unit removing the heat discharged to the outside of the motor housing by the heat pipe. As such, according to the present invention, the oil flow path-mounted cooling apparatus in the motor housing of the electric vehicle is able to rapidly move and remove the heat generated in the oil flow path to the outside of the motor housing through the heat pipe, have no condensation of heat in the motor housing, and reduce cooling load as much. In addition, the present invention is able to wind a cooling water coil, through which cooling water passes, around the oil flow path, water-cool the oil flow path itself thereby, and have a high cooling efficiency.

    본 발명은 전기차 모터하우징 내 오일유로 장착형 냉각장치에 관한 것이다. 이는, 전기차용 모터하우징의 오일유로에 결합한 상태로 모터하우징의 외부로 연장되고, 오일유로에서 발생하는 열을 모터하우징의 외부로 이동시키는 히트파이프와; 히트파이프에 의해 모터하우징 외부로 배출되는 열을 제거하는 방열부가 포함되는 것을 특징으로 한다. 상기와 같이 이루어지는 본 발명의 전기차 모터하우징 내 오일유로 장착형 냉각장치는, 오일유로에서 발생하는 열을 히트파이프를 통해 모터 하우징 외부로 신속 이동시켜 제거하므로, 모터하우징 내부에서의 열의 응축이 없어 그만큼 냉각부하를 감소시킨다. 또한 냉각수를 통과시키는 냉각수코일을 오일유로에 감아 오일유로 자체를 수냉 시키므로 냉각 효율이 양호하다.
