In accordance with the present invention, in a vehicle thermal management system (100), flow of engine cooling water circulating an engine (110) selectively via a heater core (200) and a radiator (300) is formed. In addition, by linking an integrated thermal management (ITM) (1) and a smart single valve (SSV) (40), the optimal cooling concept of the ITM (1) enhances engine completion in an initial design stage. Moreover, through an ITM layout, the SSV (400) is used for solving an exhaust gas recirculation (EGR) condensate water problem in addition to cooling water requiring improvement. In addition, a relatively large flow rate of cooling water is joined to an EGR cooler (500) to shorten the time point of EGR use, which is advantageous for improving fuel efficiency, while enabling rapid warm-up of an engine and improving heating performance.

    본 발명의 차량 열관리 시스템(100)은 히터 코어(200), 라디에이터(300)를 선택적으로 경유하여 엔진(110)을 순환하는 엔진 냉각수 흐름이 형성되고, ITM(1)과 SSV(40)의 연계로 ITM(1)의 최적 냉각 컨셉(Concept)으로 설계 초기 엔진 완성도를 높이면서 ITM 레이아웃을 통해 SSV(400)로 EGR 응축수 문제를 개선에 필요한 냉각수에 더해 연비개선에 유리한 EGR 사용 시점 단축이 이루어지도록 상대적으로 많은 냉각수 유량을 EGR 쿨러(500)에 합류시켜주면서 엔진의 빠른 웜업과 난방성능 개선이 가능한 특징이 구현된다.
