The heat exchanger heats up the cooling water and reduces the exhaust gas. The elevated temperature of the cooling water flows into the oil heat exchanger 20 to raise the oil of the transmission 4 and the cooling water is reduced in temperature, and the elevated oil circulates to the transmission 4 side. Then, the cooled cooling water circulates to the engine 1 side after heat exchange while passing through the heater core 3 again.

이와 같이, 본 발명은 제1 및 제2 장착플레이트(51, 52), 밀봉부재(44) 등을 통해 배기가스 열교환부(10)와 오일 열교환부(20)가 통합형으로 밀착구성하고, 이를 통해 라디에이터(2)의 주변에 배치되어 있던 복수의 열교환기 중에서 오일 쿨러 등과 같은 일부의 열교환기를 EGR쿨러(배기가스 열교환기) 측으로 위치 변경할 수 있다. 이에, 라디에이터 주변공간의 슬림화를 효과적으로 구현할 뿐만 아니라 냉각수 라인 및 오일 라인의 레이아웃을 간소화할 수 있고, 차량 내의 공간 제약을 효과적으로 극복할 수 있는 장점이 있다. As described above, the present invention is configured such that the exhaust gas heat exchanger 10 and the oil heat exchanger 20 are integrated into the integrated type through the first and second mounting plates 51 and 52 and the sealing member 44. Of the plurality of heat exchangers arranged around the radiator 2, some heat exchangers such as an oil cooler can be repositioned to the EGR cooler (exhaust gas heat exchanger) side. Thus, not only can effectively implement the slimming of the radiator surrounding space, but also simplify the layout of the coolant line and the oil line, and can effectively overcome the space constraints in the vehicle.

그리고, 본 발명은 배기가스 열교환부(10)와 오일 열교환부(20)가 밀봉적으로 결합됨에 따라, 배기가스 열교환부(10)의 제1냉각수채널(42)과 오일 열교환부(20)의 제2냉각수채널(45)은 밀봉적으로 접속된다. 이에 배기가스 열교환부(10) 내에서 배기가스통로(41)들을 통과하는 배기가스와 열교환(냉각)함에 따라 승온된 냉각수는 오일 열교환부(20)의 제2냉각수채널(45) 측으로 유입되어 오일 열교환부(20)의 오일채널(44)을 통과하는 오일과 효율적으로 열교환한다. In addition, according to the present invention, the exhaust gas heat exchanger 10 and the oil heat exchanger 20 are hermetically coupled to each other, so that the first coolant channel 42 and the oil heat exchanger 20 of the exhaust gas heat exchanger 10 are sealed. The second coolant channel 45 is hermetically connected. Accordingly, the coolant heated by the heat exchange (cooling) with the exhaust gas passing through the exhaust gas passages 41 in the exhaust gas heat exchanger 10 flows into the second coolant channel 45 side of the oil heat exchanger 20 to be oil. Heat exchanges efficiently with the oil passing through the oil channel 44 of the heat exchanger 20.

특히, 본 발명은 배기가스와의 열교환을 통해 승온된 상태의 냉각수가 오일 열교환부(20)에서 오일의 온도를 가열함에 따라 차량의 초기 냉시동 시에 변속기 오일(automotive transmission oil)을 신속하게 워밍업함으로써 연비 향상 및 매연 저감을 효과적으로 구현할 수 있는 장점이 있다. In particular, according to the present invention, as the coolant in the state of being heated up through heat exchange with the exhaust gas heats the temperature of the oil in the oil heat exchanger 20, the transmission oil is warmed up rapidly during the initial cold start of the vehicle. By doing so, there is an advantage that can effectively implement fuel efficiency and smoke reduction.
