A cooling system of a hybrid vehicle is disclosed. The cooling system of a hybrid vehicle includes: an engine cooling circuit for cooling an engine generating power with cooling water; a heating element cooling circuit for cooling a heating element generating heat during operation; and a connection line performing selective connection so that the cooling water of the engine cooling circuit and the cooling water of the heating element cooling circuit can be selectively exchanged. Therefore, the cooling system of a hybrid vehicle can expand an EGR cooler operating area, perform rapid cooling, and increase fuel efficiency.
하이브리드 차량의 냉각시스템이 개시된다. 동력을 발생시키는 엔진을 냉각수로 냉각하는 엔진 냉각회로; 작동시에 열을 발생시키는 발열체를 냉각하는 발열체 냉각회로; 및 상기 엔진 냉각회로의 냉각수와 상기 발열체 냉각회로의 냉각수가 선택적으로 교류되도록 선택적으로 연결하는 연결라인을 포함하여, EGR 쿨러의 작동 영역 확장, 신속한 냉방 및 연비향상을 도모할 수 있다.
