The present invention relates to a motor cooling system of an electric vehicle using a thermoelectric element, which can be simply provided corresponding to a curved shape of a motor for driving the electric vehicle, and can effectively control the temperature of the motor by immediately reacting to the temperature of the motor changing momentarily and instantaneously. According to the present invention, the system comprises: a motor cooling module including a pair of cover plates facing each other at a distance from each other, and a plurality of thermoelectric elements provided in spaces between the cover plates to provide cold air into the motor; a temperature sensor sensing the temperature of the motor; and a controller controlling the thermoelectric element to provide the cold air to a contact surface of the motor side when the temperature of the motor sensed by the temperature sensor is higher than or equal to a predetermined temperature.

    본 발명은 열전소자를 이용한 전기자동차의 모터 냉각시스템에 관한 것으로, 전기자동차를 구동하는 모터의 곡면 형상에 대응하여 간단히 설치되며 시시각각 순간적으로 변하는 모터의 온도에 즉각 반응하여 모터의 온도를 효과적으로 제어할 수 있도록 한 것이다. 이러한 본 발명은, 서로에 대하여 이격을 두고 대면하는 한 쌍의 커버 플레이트, 상기 커버 플레이트 간 이격 공간에 다수 설치되어 모터 내부로 냉기를 제공할 수 있도록 한 열전소자로 이루어지는 모터 냉각모듈, 모터의 온도를 측정하는 온도센서, 온도센서가 측정한 모터의 온도가 일정 온도 이상인 경우에는 상기 열전소자가 상기 모터 쪽 접촉면으로 냉기를 제공하도록 제어하는 제어기를 포함하는 것을 특징으로 한다.
