In accordance with the present invention, a vehicle thermal management system (100) comprises a heater core (200), a radiator (300), an exhaust gas recirculation (EGR) cooler (500), an oil warmer (600), an auto transmission fluid (ATF) warmer (700), and a plurality of cooling water circulation/distribution systems (100-1, 100-2, 100-3) in which flow of engine cooling water circulating an engine (110) selectively via exhaust heat recovery systems (EHRS) (800) is formed by connection with an integrated thermal management (ITM) valve (1). While a four-port ITM layout of the ITM (1) enables quick warming up of an engine and ATF/engine oil at the same time, fuel efficiency and heating performance can be improved at the same time by shortening the time point of EGR use.

    본 발명의 차량 열관리 시스템(100)은 히터 코어(200), 라디에이터(300), EGR 쿨러(500), 오일워머(600), ATF 워머(700), EHRS(Exhaust Heat Recovery Systems)(800)를 선택적으로 경유하여 엔진(110)을 순환하는 엔진 냉각수 흐름이 ITM(Integrated Thermal Management Valve)(1)과 연계로 형성되는 복수개의 냉각수 순환/분배 시스템(100-1,100-2,100-3)이 포함됨으로써 ITM(1)의 4포트 ITM 레이아웃을 통해 엔진과 ATF 오일/엔진오일에 대한 웜업을 동시에 빠르게 구현하면서 EGR 사용 시점 단축으로 연비와 난방 성능을 동시에 개선할 수 있는 특징이 구현된다.
