복합 냉각 구조를 구비한 모터 하우징{Motor housing with hybrid cooling structure}Motor housing with hybrid cooling structure

본 발명은 모터 냉각 기술에 관련한 것으로, 특히 복합 냉각 구조를 구비한 모터 하우징에 관한 것이다.The present invention relates to motor cooling technology, and more particularly to a motor housing having a complex cooling structure.

최근 대중들의 전기자동차에 대한 관심이 높아짐에 따라 전기자동차의 성능에 대한 관심이 증가하고 있다. 전기자동차 성능에 영향을 미치는 인자들은 수없이 많지만, 그 중에서 단연코 전기자동차의 핵심부품은 구동모터(Traction motor)라 할 수 있다. Recently, as the public's interest in electric vehicles increases, interest in the performance of electric vehicles is increasing. There are countless factors that affect the performance of an electric vehicle, but among them, the core part of an electric vehicle is the traction motor.

구동모터의 성능에 미치는 요인들은 코어형상, 극수, 점적률 등 다양하다. 동일한 모터 크기 및 외관을 가지고 있더라도 높은 성능(Performance)을 달성하기 위해서 냉각성능을 무시할 수 없는 실정이다. Factors that affect the performance of a driving motor are diverse, such as core shape, number of poles, and space factor. Even if the motor has the same size and appearance, cooling performance cannot be neglected in order to achieve high performance.

구동모터는 고정자(Stator)에서 많은 발열이 발생하므로 지속적으로 냉각이 필요하다. 냉각이 정상적으로 이루어지지 않을 경우에 목표성능 미달성 및 인명피해까지 이어질 수 있다. 모터 냉각 방법은 수냉, 공냉, 유냉, 직접식 냉각 방식이 존재한다. Since a lot of heat is generated in the stator, the driving motor needs continuous cooling. If cooling is not performed normally, it may lead to failure to achieve the target performance and even casualties. Motor cooling methods include water cooling, air cooling, oil cooling, and direct cooling.

대한민국 공개특허 제10-2018-0038781호(2018.04.17)에서 냉각매체를 유동시키는 유동 통로를 모터 하우징의 내부에 형성하고, 유동 통로와 연결되는 냉각매체 유입부 및 배출부를 형성하며, 유동 통로와 연결되는 적어도 하나의 관통 홀을 구비한 구동모터의 냉각유닛을 제안하고 있다.In Korean Patent Laid-Open No. 10-2018-0038781 (April 17, 2018), a flow passage through which the cooling medium flows is formed inside the motor housing, and a cooling medium inlet and outlet connected to the flow passage are formed, and the flow passage and A cooling unit of a driving motor having at least one through hole to be connected is proposed.

기존에는 구동모터의 하우징(Housing) 제작시, 복잡한 수로부가 포함되어 있으면 중력주조하고, 복잡한 수로부가 없는 단순한 형상이라면 다이캐스팅 제작하고 있다.Conventionally, when manufacturing the housing of a drive motor, gravity casting is used if a complicated water channel part is included, and die casting is produced if a simple shape without a complicated water channel part is included.

중력 주조로 하우징 제작시 수로부를 형상화 시키기 위해서 코어(Core)를 넣어 수로형상을 만들어야 하고, 다이캐스팅으로 하우징 제작시에는 상형, 하형 다이(Die)를 제작해야 하므로, 양산성(제작성)을 고려해볼 때 추가적인 부품과 시간이 필요하고, 투자비와 작업 수(공수)가 증가하여 제조 비용이 상승한다.When manufacturing a housing by gravity casting, in order to shape the water passage, it is necessary to insert a core to make the water passage shape. When additional parts and time are required, the investment cost and the number of operations (man-hours) increase, resulting in an increase in manufacturing cost.
