A cooling passage structure of a driving motor housing of the present invention comprises a stator located on the inner peripheral surface of the housing, and a cooling passage in which a stator concave portion is formed at a certain depth along the outer circumference of the stator toward the center of the stator and is formed between the stator and the housing, wherein the cooling passage is divided into a first cooling passage and a second cooling passage by a passage dividing wall, the first cooling passage and the second cooling passage are parallel to each other, the first cooling passage is connected to an inlet, the second cooling passage is connected to an outlet, the inlet and the outlet are arranged side by side on the outer surface of the housing, the first cooling passage is connected to the second cooling passage through a U-turn unit, and the U-turn unit may be formed at a certain distance from the inlet and the outlet. Accordingly, the present invention may exhibit efficient cooling performance.

    본 발명의 구동모터 하우징의 냉각유로구조는 하우징의 내주면에 위치하는 스테이터, 상기 스테이터의 외주를 따라 상기 스테이터의 중심을 향해 일정 깊이로 스테이터 오목부가 형성된 냉각유로가 상기 스테이터와 상기 하우징 사이에 형성되고, 상기 냉각유로는 유로분리벽에 의해 제1 냉각유로 및 제2 냉각유로로 구분되고, 상기 제1 냉각유로 및 제2 냉각유로로는 서로 평행하며, 상기 제1 냉각유로는 유입구와, 상기 제2 냉각유로는 유출구와 연결되며, 상기 유입구 및 유출구는 상기 하우징의 외면에 나란히 배치되고, 상기 제1 냉각유로는 유턴부를 통해 상기 제2 냉각유로와 연결되며, 상기 유턴부는 상기 유입구 및 상기 유출구로부터 일정간격 이격되어 형성될 수 있다.
