Description

자동차용 쿨링파이프 일체형 오일쿨러{One-piece type oil cooler of cooling pipe for automobile}One-piece type oil cooler of cooling pipe for automobile}

본 발명은 자동차용 쿨링파이프 일체형 오일쿨러에 관한 것으로서 보다 상세히는 EGR쿨러(exhaust gas recirculation cooler)에서 필요로 하는 냉각수를 라디에이터에서 직접 공급하지 않고, 오일쿨러로 공급된 냉각수가 EGR쿨러로 들어가도록 하므로서 라디에이터와 EGR쿨러를 연결하기 위한 연결호스를 삭제할 수 있음에 따라 협소한 엔진룸내에서 연결호스를 설치하기 위한 공간확보를 할 필요가 없어 작업성이 좋아져 그만큼 생산성이 향상되는 자동차용 쿨링파이프 일체형 오일쿨러에 관한 것이다.The present invention relates to an automotive cooling pipe integrated oil cooler, and more specifically, to the cooling water supplied to the oil cooler to enter the EGR cooler without directly supplying the cooling water required by the exhaust gas recirculation cooler from the radiator. As the connection hose for connecting the radiator and the EGR cooler can be removed, there is no need to secure space for installing the connection hose in the narrow engine room, which improves productivity and increases the productivity of the automotive cooling pipe integrated oil cooler. It is about.

일반적으로 자동차의 엔진을 구성하는 여러부분들에서는 엔진의 작동중에 마찰이 발생하는데 각 마찰요소의 원활한 작동과 밀봉및 냉각을 위해서는 지속적으로 윤활유를 공급해줄 필요가 있어 오일펌프를 작동시켜 엔진의 각 부분으로 윤활용 오일을 공급하게 된다.In general, various parts of the engine of a car generate friction during operation of the engine. For smooth operation, sealing, and cooling of each friction element, it is necessary to continuously supply lubricating oil. To supply lubricating oil.

그런데 엔진의 여러부분에서 발생되는 고온의 열에 의해 윤활용오일의 온도 가 점차 상승하고 점도가 저하되므로써 윤활유로서의 기능을 상실하게 되므로 윤활유 오일을 지속적으로 냉각시켜 주어야 한다.However, as the temperature of the lubricating oil gradually rises and the viscosity decreases due to the high temperature heat generated in various parts of the engine, the function of the lubricating oil is lost, so the lubricating oil must be continuously cooled.

이처럼 윤활용 오일을 냉각시켜 주기 위하여 시용하는 것이 오일쿨러인데 오일쿨러는 냉각방식에 따라 공랭식과 수냉식으로 나누어진다.The oil cooler is used to cool the lubricating oil. The oil cooler is divided into air cooling and water cooling according to the cooling method.

수냉식 오일쿨러에서는 라디에이터에서 냉각수를 공급받아 엔진오일을 냉각시켜준다.In the water-cooled oil cooler, the radiator receives coolant to cool the engine oil.

한편, 자동차의 배출가스는 일산화탄소(CO), 질소산화물(NOx), 탄화수소(HC)등의 유해물질이 포함되어 있는바 연소과정에서 발생하는 상기 3원소중 일산화탄소와 탄화수소에 대하여 질소산화물은 항상 반대의 인과관계를 가지고 있다.On the other hand, the exhaust gas of automobiles contains harmful substances such as carbon monoxide (CO), nitrogen oxides (NOx), hydrocarbons (HC), and nitrogen oxides are always opposed to carbon monoxide and hydrocarbons among the three elements generated in the combustion process. Has a causal relationship with

즉, 실용적인 출력범위에서 일산화탄소와 탄화수소가 가장 감소하는 시점에 질소산화물은 가장 많이 발생하는데 이러한 질소산화물은 연료가 완전 연소할수록 즉, 엔진이 고온일수록 질소산화물의 발생량은 증가하게 된다.In other words, nitrogen oxides are most generated when carbon monoxide and hydrocarbons are decreased in the practical output range, and the nitrogen oxides are increased as the fuel is completely burned, that is, the engine is hot.

따라서 질소산화물 등의 배출가스를 줄이는 다양한 기술이 개발되고 있는바 그중 하나가 배기가스 재순환장치이다.Therefore, various technologies for reducing emissions such as nitrogen oxides have been developed, one of which is an exhaust gas recirculation device.

배기가스 재순환장치는 다른 유해물질의 급증없이 질소산화물의 발생량을 줄이기 위해서는 혼합비를 이론 공연비로 유지하면서 연소실로 흡입되는 혼합기중에 기 연소가스의 일부를 공급하므로써 신기의 양을 줄임과 동시에 연소가스의 열용량을 증가시켜 화염의 온도를 낮추는 방법으로 사용되는 장치이다.The exhaust gas recirculation system reduces the amount of fresh air by supplying a portion of the combustion gas to the mixer drawn into the combustion chamber while maintaining the mixing ratio at the theoretical air-fuel ratio in order to reduce the generation of nitrogen oxides without a sudden increase in other harmful substances. It is a device used to decrease the temperature of the flame by increasing the.

즉, 배기가스 재순환장치는 배출가스중 배기가스를 흡기계로 재순환시켜 실린더내의 연소온도를 낮추어 질소산화물의 발생을 억제하는 장치로서 배기가스중의 질소산화물을 저감하는 수단으로 배기가스의 일부를 흡기계통에 되돌려서 혼합기가 연소할 때 최고온도를 낮게하여 질소산화물의 생성량을 적게하는 장치를 말하는 것이다.In other words, the exhaust gas recirculation apparatus is a device for reducing the nitrogen oxide in the exhaust gas by reducing the combustion temperature in the cylinder by recycling the exhaust gas in the exhaust gas to the intake machine. It is a device that lowers the maximum temperature when the mixer burns and returns to the system to reduce the production of nitrogen oxides.

이에따라 차량에는 EGR쿨러를 설치한후 라디에에터에서 공급되는 냉각수를 EGR쿨러로 공급하여 배기가스를 냉각시켜 질소산화물의 발생을 줄이도록 하는 것이다.Accordingly, after the EGR cooler is installed in the vehicle, the cooling water supplied from the radiator is supplied to the EGR cooler to cool the exhaust gas to reduce the generation of nitrogen oxides.

그러나 종래 냉각수를 EGR쿨러로 공급하는데에는 많은 문제점이 있는 것으로서 이를 상세히 설명하면 다음과 같다.However, there are many problems in supplying the conventional cooling water to the EGR cooler as described in detail as follows.

즉, 종래에는 라디에이터에서 공급되는 냉각수를 EGR쿨러로 공급하기 위해서는 별도의 라디에이터와 EGR쿨러를 연결하는 공급호스를 설치하여야 하는바 수많은 부품이 설치되는 협소한 엔진룸내에서 공급호스를 설치하기 위한 공간확보가 용이하지 못해 그만큼 작업성이 저하되어 생산성이 떨어지는 것은 물론 라디에이터와 EGR쿨러 사이의 간격이 멀어 공급호스의 길이도 길어짐에 따라 부품비도 상승하는 문제점이 있었다.That is, conventionally, in order to supply the coolant supplied from the radiator to the EGR cooler, a separate supply hose for connecting the radiator and the EGR cooler must be installed, thus securing a space for installing the supply hose in a narrow engine room in which many parts are installed. It is not easy to reduce the workability by the decrease in productivity, as well as the distance between the radiator and the EGR cooler has a problem that the parts cost increases as the length of the supply hose is longer.

이에 본 발명은 이와같은 종래의 문제점을 해결하기 위한 것으로 본 발명의 목적은 오일쿨러에 공급되는 냉각수를 EGR쿨러로 보내 배기가스를 냉각시켜 주므로서 라디에이터에서 냉각수를 EGR쿨러로 보내지 않아도 되므로 라디에이터와 EGR쿨 러를 연결하기 위한 공급호스를 협소한 엔진룸내에 설치하지 않아 작업성이 향상되는 것은 물론 오일쿨러와 EGR쿨러와의 사이가 가까워 연결파이프의 길이를 짧게 구성할 수 있어 부품비가 절감되는 자동차용 쿨링파이프 일체형 오일쿨러를 제공하기 위한 것이다.Accordingly, the present invention is to solve such a conventional problem, and an object of the present invention is to send the coolant supplied to the oil cooler to the EGR cooler to cool the exhaust gas so that the radiator does not have to send the coolant to the EGR cooler. As the supply hose for connecting the cooler is not installed in a narrow engine room, the workability is improved and the distance between the oil cooler and the EGR cooler is close, so the length of the connection pipe can be shortened. It is to provide a cooling pipe integrated oil cooler.

본 발명의 목적을 달성하기 위해 본 발명은 자동차용 오일쿨러를 구성함에 있어서, 워터펌프에서 공급되는 냉각수로 엔진오일을 냉각시키는 오일쿨러본체;In order to achieve the object of the present invention, the present invention comprises an oil cooler main body for cooling the engine oil with a coolant supplied from a water pump in the configuration of an automotive oil cooler;

오일쿨러본체의 하단에 구비되며, 오일쿨러본체를 오일필터하우징의 일 측면에 장착시켜 주는 오일쿨러장착부; 오일쿨러본체의 오일을 냉각한 냉각수가 EGR쿨러로 공급되게 하기 위해 오일쿨러장착부 일 부위에 일체형으로 설치되는 냉각수토출파이프; EGR쿨러로 공급한 냉각수를 회수하기 위해 오일쿨러장착부 일 부위에 일체형으로 설치되는 냉각수유입파이프; 로 이루어진 것을 특징으로 한다. An oil cooler mounting portion provided at a lower end of the oil cooler body and mounting the oil cooler body to one side of the oil filter housing; Cooling water discharge pipe which is integrally installed in one portion of the oil cooler mounting portion in order to supply the cooling water to cool the oil of the oil cooler body to the EGR cooler; A coolant inlet pipe integrally installed at one portion of the oil cooler mounting part to recover the coolant supplied to the EGR cooler; Characterized in that consisting of.

이와같은 본 발명은 라디에이터에서 오일쿨러로 냉각수를 공급하면 오일쿨러에서 다시 EGR쿨러로 냉각수를 공급하여 EGR쿨러로 공급된 배기가스를 냉각시켜 주므로서 별도로 라디에이터에서 EGR쿨러로 냉각수를 공급할 필요가 없어 라디에이터와 EGR쿨러를 연결하기 위한 공급호스를 협소한 엔진룸내에 설치할 필요가 없어 작업성이 향상되는 것은 물론 부품비도 절감할 수 있는 효과가 있다.In the present invention, when the coolant is supplied from the radiator to the oil cooler, the coolant is supplied from the oil cooler to the EGR cooler again to cool the exhaust gas supplied to the EGR cooler, and thus, the radiator is not required to be supplied from the radiator to the EGR cooler. There is no need to install a supply hose to connect the EGR cooler in a narrow engine room, which improves workability and reduces component costs.

이러한 본 발명은 자동차용 오일쿨러를 구성함에 있어서, 워터펌프에서 공급되는 냉각수로 엔진오일을 냉각시키는 오일쿨러본체(200); 오일쿨러본체(200)의 하단에 구비되며, 오일쿨러본체(200)를 오일필터하우징(100)의 일 측면에 장착시켜 주는 오일쿨러장착부(210); 오일쿨러본체(200)의 오일을 냉각한 냉각수가 EGR쿨러로 공급되게 하기 위해 오일쿨러장착부(210) 일 부위에 일체형으로 설치되는 냉각수토출파이프(220); EGR쿨러로 공급한 냉각수를 회수하기 위해 오일쿨러장착부(210) 일 부위에 일체형으로 설치되는 냉각수유입파이프(230); 로 이루어진 것을 특징으로 한다.The present invention comprises an oil cooler main body 200 for cooling the engine oil with the cooling water supplied from the water pump in configuring the automotive oil cooler; An oil cooler mounting portion 210 provided at a lower end of the oil cooler body 200 to mount the oil cooler body 200 to one side of the oil filter housing 100; In order to ensure that the coolant that cools the oil of the oil cooler main body 200 is supplied to the EGR cooler, the oil cooler mounting part 210 is integrally formed in one part. Cooling water discharge pipe 220 is installed; Cooling water inlet pipe 230 is integrally installed in one portion of the oil cooler mounting portion 210 to recover the cooling water supplied to the EGR cooler; Characterized in that consisting of.

이러한 본 발명은 라디에이터(도면중 미도시)에서 냉각된 냉각수를 이용하여 EGR쿨러(도면중 미도시)로 유입된 배기가스를 냉각시켜 주는 것은 종래와 마찬가지이다. The present invention uses the cooling water cooled in a radiator (not shown) to cool the exhaust gas introduced into the EGR cooler (not shown) as in the prior art.

그러나 본 발명에서의 특징은 라디에이터에서 냉각수를 EGR쿨러로 바로 보내 는 것이 아니고, 라디에이터에서 오일쿨러로 공급된 냉각수가 EGR쿨러로 들어가 배기가스를 식혀주도록 한 것이다.However, the feature of the present invention is that the radiator does not directly send the coolant to the EGR cooler, but the coolant supplied from the radiator to the oil cooler enters the EGR cooler to cool the exhaust gas.

즉, 본 발명은 도 1에서 예시한 바와같이 오일쿨러본체(200)를 오일필터하우징(100)에 설치하기 위한 오일쿨러장착부(210)에 냉각수토출파이프(220)와 냉각수유입파이프(230)를 설치한후 냉각수토출파이프(220)와 냉각수유입파이프(230)의 끝단은 오일쿨러본체(200)와 근접된 위치에 설치되어 있는 EGR쿨러로 연결되게 한 것이다.That is, according to the present invention, the coolant discharge pipe 220 and the coolant inlet pipe 230 are installed in the oil cooler mounting part 210 for installing the oil cooler body 200 in the oil filter housing 100 as illustrated in FIG. 1. After installation, the ends of the coolant discharge pipe 220 and the coolant inlet pipe 230 are connected to the EGR cooler installed at a position close to the oil cooler main body 200.

따라서 라디에이터에서 냉각수를 오일쿨러본체(200)로 공급하면 냉각수는 오일쿨러본체(200)로 들어가 오일을 냉각시켜준후 다시 냉각수토출파이프(220)를 통해 EGR쿨러로 들어가 순환되면서 배기가스를 식혀준후 냉각수유입파이프(230)를 통해 다시 오일쿨러본체(200)속으로 들어오게 된다.Therefore, when the coolant is supplied from the radiator to the oil cooler main body 200, the coolant enters the oil cooler main body 200, cools the oil, enters the EGR cooler through the coolant discharge pipe 220, circulates, and cools the exhaust gas. The oil comes into the oil cooler body 200 again through the inflow pipe 230.

이처럼 본 발명에서는 라디에이터에서 공급하는 냉각수는 오일쿨러로만 공급하고 EGR쿨러로는 공급되지 않아 라디에이터와 EGR쿨러를 연결하는 공급호스를 별도로 설치할 필요가 없는 것이다.As such, in the present invention, the coolant supplied from the radiator is supplied only to the oil cooler and is not supplied to the EGR cooler. Therefore, it is not necessary to separately install a supply hose connecting the radiator and the EGR cooler.

즉, 본 발명에서는 오일쿨러본체(200)를 오일필터하우징(100)에 설치하기 위해서 오일쿨러본체(200)의 하단 주연을 따라 돌출형의 플랜지를 구비하여 오일쿨러장착부(210)를 형성하고, 오일쿨러장착부(210)의 돌출된 플랜지 일 부위에는 오일쿨러본체(200)를 오일필터하우징(100)에 장착하기 위한 다수의 볼트공(211)을 형성하였다.That is, in the present invention, in order to install the oil cooler main body 200 in the oil filter housing 100, the oil cooler mounting portion 210 is formed by having a flange of a protruding shape along the lower periphery of the oil cooler main body 200, A portion of the protruding flange of the oil cooler mounting portion 210 formed a plurality of bolt holes 211 for mounting the oil cooler body 200 to the oil filter housing 100.

따라서 오일쿨러본체(200)를 오일필터하우징(100)에 설치하기 위해서는 오일 필터하우징(100)에 오일쿨러장착부(210)를 밀착시킨후 플랜지에 형성된 볼트공(211)을 통해 볼트(도면중 미도시)를 체결하면 오일쿨러본체(200)가 오일필터하우징(100)에 견고하게 고정된다.Therefore, in order to install the oil cooler main body 200 in the oil filter housing 100, the oil cooler mounting part 210 is brought into close contact with the oil filter housing 100 and then bolted through a bolt hole 211 formed in a flange (not shown in the drawing). C), the oil cooler body 200 is firmly fixed to the oil filter housing 100.

그리고 오일쿨러장착부(210)의 돌출된 플랜지 중 다른 일 부위에는 냉각수토출파이프(220)와 냉각수유입파이프(230)를 일정간격 이격시켜 설치하기 위한 냉각수공(212)을 형성하므로서 냉각수토출파이프(220)와 냉각수유입파이프(230)를 냉각수공(212)에 끼워 설치하면 냉각수토출파이프(220)와 냉각수유입파이프(230)가 일정간격 떨어지게 설치되는 것은 물론 냉각수가 오일쿨러본체(200)에서 냉각수공(212)을 통해 냉각수토출파이프(220)를 거쳐 EHR쿨러로 들어가 순환되어 다시 냉각수유입파이프(230)로 들어가 냉각수공(212)을 통해 오일쿨러본체(200)로 들어가는 것이다.In addition, the cooling water discharge pipe 220 is formed at another portion of the protruding flange of the oil cooler mounting part 210 by forming a cooling water hole 212 for installing the cooling water discharge pipe 220 and the cooling water inlet pipe 230 at a predetermined interval. ) And the cooling water inlet pipe 230 are inserted into the cooling water hole 212 so that the cooling water discharge pipe 220 and the cooling water inlet pipe 230 are spaced apart by a predetermined interval, and the cooling water is cooled in the oil cooler body 200. Through the 212 through the cooling water discharge pipe 220 enters the EHR cooler and circulates again into the cooling water inlet pipe 230 to enter the oil cooler body 200 through the cooling water hole (212).

또한 본 발명에서는 냉각수유입파이프(230)가 끼워지는 오일쿨러장착부(210)의 냉각수공(212) 표면에는 냉각수유입파이프(230)를 지지하는 파이프지지링(240)을 설치하고, 냉각수유입파이프(230)의 일단 외주면에는 파이프지지링(240)에 걸리는 돌턱(250)을 형성하였다.In addition, in the present invention, a pipe support ring 240 for supporting the coolant inlet pipe 230 is installed on the surface of the coolant hole 212 of the oil cooler mounting unit 210 into which the coolant inlet pipe 230 is fitted, and the coolant inlet pipe ( On one outer circumferential surface of the 230 is formed a stone step (250) caught by the pipe support ring 240.

즉, 냉각수유입파이프(230)를 설치하기 위해서는 냉각수공(212)표면으로 파이프지지링(240)을 설치한후 냉각수유입파이프(230)를 파이프지지링(240)을 관통하여 냉각수공(212)에 끼워 하향으로 내려 냉각수유입파이프(230)의 외주면에 형성된 돌턱(250)이 파이프지지링(240)에 밀착되게 하면 냉각수유입파이프(230)는 더이상 하향으로 내려가지를 않는 것이므로 이는 냉각수유입파이프(230)를 오일쿨러장착 부(210)에 설치시 항시 냉각수유입파이프(230)의 진입깊이를 일정하게 유지할 수 있는 것이다.That is, in order to install the coolant inlet pipe 230, the pipe support ring 240 is installed on the surface of the coolant hole 212, and then the coolant inlet pipe 230 passes through the pipe support ring 240. If the sill 250 formed on the outer circumferential surface of the coolant inlet pipe 230 is brought into close contact with the pipe support ring 240, the coolant inlet pipe 230 does not go down any more, which is why the coolant inlet pipe ( When the 230 is installed in the oil cooler mounting part 210, the entrance depth of the cooling water inlet pipe 230 can be maintained at a constant level.
