The present invention relates to an apparatus for improving performance of an EGR cooler and an intercooler heat exchanger.

일반적으로 엔진의 실린더 헤드에서 나온 냉각수는 히터코어로 가게 되는데 블로워(blower)에 의해 따뜻한 공기로 방열되어 실내를 난방하게 되고, 상기 히터코어를 지난 냉각수는 다시 엔진 냉각수 입구로 들어가게 된다.Generally, the coolant from the cylinder head of the engine goes to the heater core, which is radiated by warm air by a blower to heat the room, and the coolant passing through the heater core enters the engine coolant inlet again.

그러나 겨울철에 외기온이 낮은 경우나 한랭지역에서는 냉각수 온도가 낮아서 쾌적한 실내 난방에는 한계가 있는 문제점이 있다.However, when the outside air temperature is low in the winter or in the cold region, the cooling water temperature is low, there is a problem that there is a limit to comfortable indoor heating.

또한 최근에는 녹스(nox) 저감을 위해 EGR(Exhaust Gas Recirculation : 이하 EGR 이라함)을 사용하고 있는데 흡기로 들어가는 배기가스는 온도가 높으므로 쿨러(cooler)를 사용하여 온도를 낮추어 녹스 저감과 동시에 출력저하를 막고 있다.In recent years, EGR (Exhaust Gas Recirculation) is used to reduce the nox. The exhaust gas entering the intake air has a high temperature, so the cooler is used to lower the temperature and output simultaneously. It is preventing the fall.

최근의 엔진은 체적 효율을 높이기 위해 과급 공기를 냉각하는 인터쿨러(intercooler)를 장착한 엔진(TCI 엔진)사용하고 있는데, 저온시는 흡입 공기온도가 낮은 것에도 불구하고 인터쿨러를 지나므로 냉시동에 있어 문제점이 있다.Recently, the engine is using an engine (TCI engine) equipped with an intercooler (cooling supercharged air) to increase the volumetric efficiency. At low temperatures, the engine passes through the intercooler despite the low intake air temperature. There is a problem.

그래서 모든 엔진은 에어히터(air heater)를 장착하거나 글로우 플러그(glow plug)를 두고 있다.So every engine is equipped with an air heater or has a glow plug.

본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 히터코어, EGR쿨러 및 인터쿨러의 상호간에 열전달을 이용하여 히터, EGR쿨러 및 인터쿨러의 성능을 향상시키는 히터, EGR쿨러 및 인터쿨러 열교환기의 성능 향상 장치를 제공하는데 그 목적이 있다.The present invention has been made to solve the problems of the prior art, a heater, an EGR cooler and an intercooler heat exchanger to improve the performance of the heater, EGR cooler and intercooler by using heat transfer between the heater core, the EGR cooler and the intercooler.

도 1은 본 발명에 따른 히터, EGR쿨러 및 인터쿨러 열교환기의 성능 향상 장치가 개략적으로 도시된 구성도이다.1 is a configuration diagram schematically showing an apparatus for improving performance of a heater, an EGR cooler, and an intercooler heat exchanger according to the present invention.

도 1에 도시된 바와 같이, 본 발명의 히터, EGR쿨러 및 인터쿨러 열교환기의 성능 향상 장치(1)는 EGR쿨러(10), 히터코어(20) 및 인터쿨러(30)가 서로 중첩되게 설치된 열교환기로 구성된다.As shown in FIG. 1, the apparatus 1 for improving performance of the heater, the EGR cooler, and the intercooler heat exchanger of the present invention is a heat exchanger in which the EGR cooler 10, the heater core 20, and the intercooler 30 are overlapped with each other.

한편 상기 중첩에 있어서 상기 EGR쿨러(10), 히터코어(20) 및 인터쿨러(30)가 각각 파이프로 구성되어 서로 중첩되거나, 각각 전후 또는 상하 배치 구조 모두를 포함한다.Meanwhile, in the overlapping, the EGR cooler 10, the heater core 20, and the intercooler 30 are each composed of pipes and overlap each other, or include both front and rear or top and bottom arrangement structures.

상기 히터코어(20) 및 인터쿨러(30)는 상기 EGR쿨러(10)의 배기가스로 부터 열전달이 이루어져 온도가 상승되고 상기 EGR쿨러(10)의 배기가스 온도는 상기 히터코어(20) 및 인터쿨러(30)에 의해 냉각되도록 상호간에 열전달이 이루어진다.The heater core 20 and the intercooler 30 is heated by the heat transfer from the exhaust gas of the EGR cooler 10 to increase the temperature, the exhaust gas temperature of the EGR cooler 10 is the heater core 20 and the intercooler ( The heat transfer takes place between them to be cooled by 30).

그리고 상기 EGR쿨러(10), 히터코어(20) 및 인터쿨러(30)의 각각 일측과 타측에는 입력부(10a,20a,30a)와 출력부(10b,20b,30b)가 형성된다.In addition, the input units 10a, 20a, 30a and the output units 10b, 20b, and 30b are formed at one side and the other side of the EGR cooler 10, the heater core 20, and the intercooler 30, respectively.

또한 상기 히터코어(20)의 방열을 위해 외측에 블로워(40)가 장착된다.In addition, a blower 40 is mounted on the outside for heat dissipation of the heater core 20.

상기와 같이 구성되는 본 발명에 따른 히터, EGR쿨러 및 인터쿨러 열교환기의 성능 향상 장치의 작용을 설명하면 다음과 같다.Referring to the operation of the performance improving device of the heater, EGR cooler and intercooler heat exchanger according to the present invention configured as described above are as follows.

도 2는 본 발명에 따른 히터, EGR쿨러 및 인터쿨러 열교환기의 성능 향상 장치가 설치되어 작용이 도시된 상태도이다.Figure 2 is a state diagram showing the action is installed to improve the performance of the heater, EGR cooler and intercooler heat exchanger according to the present invention.

도 2에 도시된 바와 같이, 히터코어(20), EGR쿨러(10) 및 인터쿨러(30)를 서로 중첩되게 설치하여 상호간에 열전달이 가능하게 한 히터, EGR쿨러 및 인터쿨러 열교환기(1)가 구비되어 엔진(2)의 실린더 헤드(미도시)에서 나온 냉각수는 상기 히터, EGR쿨러 및 인터쿨러 열교환기(1)의 히터코어(20)로 가게 되는데 블로워(40)에 의해 따뜻한 공기로 방열되어 실내를 난방하게 되고, 상기 히터코어(20)를 지난 냉각수는 다시 엔진 냉각수 입구로 들어가게 된다.As shown in FIG. 2, the heater core 20, the EGR cooler 10, and the intercooler 30 are installed to overlap each other, and the heater, the EGR cooler, and the intercooler heat exchanger 1, which allow heat transfer to each other, are provided. The coolant from the cylinder head (not shown) of the engine 2 is directed to the heater core 20 of the heater, the EGR cooler and the intercooler heat exchanger 1, which is radiated by warm air by the blower 40, After the heating, the coolant passing through the heater core 20 enters the engine coolant inlet again.

이때 가장 고온인 상기 EGR쿨러(10)의 배기가스로부터 상기 히터코어(20) 냉각수로 열전달이 이루어져 상기 히터코어(20) 냉각수의 온도가 상승되어 히터 성능을 향상시킨다.At this time, heat is transferred from the exhaust gas of the EGR cooler 10, which is the highest temperature, to the heater core 20 cooling water, thereby increasing the temperature of the heater core 20 cooling water, thereby improving heater performance.

The heat exchange is performed to heat exchange) so that the exhaust gas temperature of the EGR cooler 10 is cooled by the heater core 20 and the intercooler 30 to improve the performance of the EGR cooler 10.

한편 상기 블로워(40)가 작동되지 않은 상태에서도 열교환이 일어나므로 상기 EGR쿨러(10)의 성능에는 큰 차이가 없다.On the other hand, since the heat exchange occurs even in the state in which the blower 40 is not operated, there is no big difference in the performance of the EGR cooler 10.

또한 별도의 EGR쿨러를 위한 냉각수 라인이 필요없고 엔진 냉각수 유량도 그대로 유지되므로 문제가 없으며, 저온 상태에서 공기 온도를 상승시키기 위한 에어히터나 글로우 플러그가 필요하지 않다.It also eliminates the need for a separate coolant line for the EGR cooler and keeps the engine coolant flow intact, eliminating the need for air heaters or glow plugs to raise the air temperature at low temperatures.

도면에서 4는 EGR밸브를, 5는 라디에이터를 의미하고, a는 흡기를, b는 배기를 의미한다.In the figure, 4 means an EGR valve, 5 means a radiator, a means intake and b means exhaust.

그리고 기호 ↑는 냉각수의 흐름을, 기호 ?? 는 배기가스의 흐름을 의미한다.And the symbol ↑ represents the flow of coolant, the symbol ?? Means the flow of exhaust gas.
