Abstract

본 발명은 전기 자동차의 구동에 관련된 모터, 인버터, DC-DC 변환기 및 충전자어치에 능동적으로 냉각수를 유입하도록 상기 장치들을 연결하는 직병렬 복합형의 냉각수 순환 통로를 만들고, 그 통로의 개폐를 온도센서의 온도조건을 이용하여 궤환제어하도록 수냉식 냉각장치를 구현함으로써,실제 주행시의 구동효율을 극대화한 것이다.The present invention creates a series-parallel combined coolant circulation passage connecting the devices to actively introduce coolant into a motor, an inverter, a DC-DC converter and a charger value related to the driving of an electric vehicle, and to open and close the passage. By implementing a water-cooled cooling device to control the feedback using the temperature conditions of the sensor, the driving efficiency during actual driving is maximized.
