According to the present invention, electric vehicle indoor air conditioning and heat management of a battery, a motor, an inverter, or the like of an electronic component can be integrated and performed with a system. The minimum number of heat exchangers and flow path control valves can realize an air conditioning mode of cooling, heating, dehumidification, battery cooling, battery temperature rising, or the like. Through a water-cooled plate-shaped heat exchanger, a refrigerant is not required for being directly heat-exchanged with outdoor air to reduce a decline in heating performance and efficiency in low-temperature heating. Moreover, a refrigerant cycle unit including a compressor, a water-cooled condenser, a water-cooled evaporator, and an expansion device can be integrated with a single case, and production costs can be reduced without a high-priced refrigerant conversion valve and a refrigerant hose. According to the present invention, an electric vehicle integrated heat management system is small to reduce an installation space and increase a freedom degree of an installation position.
본 발명은 전기 자동차 실내 공조와 배터리, 모터, 인버터 등의 전장품의 열관리를 통합하여 실시하는 시스템을 구할 수 있고, 최소한의 열교환기와 유로제어밸브로 냉방, 난방, 제습, 배터리 냉각, 배터리 승온 등의 공조 모드를 구현할 수 있으며, 수냉식 판형 열교환기로 냉매가 외기와 직접 열교환할 필요가 없기 때문에 저온 난방에서도 난방 성능 및 효율 저하가 크지 않고, 냉매사이클부(압축기, 수냉식 응축기, 수냉식 증발기, 팽창장치)를 단일 케이스에 집적 가능하며, 고가의 냉매 전환 밸브와 냉매 호스가 불필요하여 원가 절감이 가능하며, 소형으로 설치 공간을 축소하고 설치 위치의 자유도를 높일 수 있는 전기 자동차 통합 열관리시스템을 제공한다.
