In accordance with the present invention, a vehicle thermal management system (100) comprises mechanical/electric water pumps (120A,B), a heater core (200), high temperature (HT)/low temperature (LT) radiators (300A,B), 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, 100-4) in which flow of engine cooling water circulating an engine (110) selectively via an intercooler (900-1) is formed by connection between an integrated thermal management (ITM) (1) and a smart single valve (SSV) (40). While a four-port layout of the ITM (1) enables quick warming up of an engine and engine oil/ATF at the same time, turbo boiling can be prevented during ignition key off by linking the SSV and an electric water pump (EWP) of a water-cooling-type intercooler.

    본 발명의 차량 열관리 시스템(100)은 기계/전동식 워터펌프(120A,B), 히터 코어(200), HT/LT 라디에이터(300A,b), EGR 쿨러(500), 오일워머(600), ATF 워머(700), 인터쿨러(900-1)를 선택적으로 경유하여 엔진(110)을 순환하는 엔진 냉각수 흐름이 ITM(1)과 SSV(40)의 연계로 형성되는 복수개의 냉각수 순환/분배 시스템(100-1,100-2,100-3,100-4)이 포함됨으로써 ITM(1)의 4포트 레이아웃으로 엔진과 엔진오일/ATF 오일에 대한 웜업을 동시에 빠르게 구현하면서 SSV 및 수냉식 인터쿨러의 EWP(Electric Water Pump) 연계로 시동오프(Ignition Key Off)시 터보 보일링을 방지할 수 있는 특징이 구현된다.
