Description

인터쿨러와 일체로 형성된 라디에이터{Radiator structure}Radiator formed integrally with intercooler

본 발명은 인터쿨러와 일체로 형성된 라디에이터에 관한 것으로, 보다 상세하게는 엔진의 냉각수를 냉각하기 위해 엔진의 전방에 형성되던 라디에이터와, 터보차저의 성능향상을 위해 엔진룸의 일측에 별도로 형성되던 인터쿨러를 일체화하여 엔진룸의 공간이 효율적으로 활용되도록 하는 인터쿨러와 일체로 형성된 라디에이터에 관한 것이다.The present invention relates to a radiator formed integrally with the intercooler, and more particularly, a radiator formed in front of the engine to cool the coolant of the engine, and an intercooler separately formed at one side of the engine room for improving the performance of the turbocharger. It relates to a radiator formed integrally with the intercooler to integrate the space of the engine room efficiently.

일반적으로 디젤엔진에는 배기가스의 배출압력을 이용하여 흡입공기를 가압한 후 연소실로 공급되도록 하는 터보차저가 형성되어 있다.In general, a diesel engine is provided with a turbocharger that pressurizes intake air by using an exhaust pressure of exhaust gas and supplies the same to the combustion chamber.

도 3은 디젤엔진의 일반적인 흡입공기 공급시스템을 간략하게 도시한 것으로서, 엔진(11)으로 공급되는 흡입공기는 에어덕트(12)로 유입되어 에어클리너(13)에서 정화된 후, 배기가스의 배출압력으로 회전되는 터보차져(14)에 의해 가압되고, 가압된 흡입공기는 인터쿨러(15)에서 냉각된 후, 스로틀밸브(16)의 개도량에 따라서 스로틀바디(17)에서 스월을 일으키며 연소실로 유입되도록 구성된다.FIG. 3 schematically illustrates a general intake air supply system of a diesel engine, and intake air supplied to the engine 11 flows into the air duct 12 and is purified by the air cleaner 13 and then discharged from exhaust gas. The pressurized intake air, which is pressurized by the turbocharger 14 which is rotated by pressure, is cooled in the intercooler 15 and then swirls in the throttle body 17 according to the opening amount of the throttle valve 16 and enters the combustion chamber. It is configured to be.

엔진(11)의 배기매니폴드에서 배출되어 상기한 터보차저(14)를 가동시킨 배기가스는 배기관에 형성된 촉매(18)에서 유해성분이 산화 및 환원된 후 머플러를 통해 대기로 배출된다.The exhaust gas discharged from the exhaust manifold of the engine 11 to operate the turbocharger 14 is oxidized and reduced in the catalyst 18 formed in the exhaust pipe and then discharged to the atmosphere through the muffler.

그리고 수냉식 냉각시스템이 적용하는 차량의 엔진의 전방에는 냉각수의 냉각을 위한 라디에이터가 설치된다. 도 4는 일반적인 라디에이터의 장착구조를 보인 도면으로, 엔진을 순환하며 가열된 냉각수는 상기 라디에이터(20)의 상부탱크(21)에서 하부탱크(22)로 코어(23)를 통해 흐르게 된다. 이 과정에서 라디에이터(20) 후방에 형성되는 냉각팬(24)이 작동되어 상기한 코어(23)를 흐르는 냉각수를 냉각하게 되는 것이다.And a radiator for cooling the coolant is installed in front of the engine of the vehicle to which the water-cooled cooling system is applied. FIG. 4 is a view illustrating a mounting structure of a general radiator, in which a coolant heated while circulating the engine flows through the core 23 from the upper tank 21 to the lower tank 22 of the radiator 20. In this process, the cooling fan 24 formed at the rear of the radiator 20 is operated to cool the cooling water flowing through the core 23.

상기한 바와 같이 엔진(11)의 냉각하기 위한 냉각수는 라디에이터(20)에서냉각되고, 터보차저(14)의 효율을 상승시키기 위한 공기는 인터쿨러(15)에서 냉각된다.As described above, the coolant for cooling the engine 11 is cooled in the radiator 20, and the air for increasing the efficiency of the turbocharger 14 is cooled in the intercooler 15.

그러나 상기한 인터쿨러와 라디에이터는 각각 공기와 냉각수를 냉각하는 기능을 하는 것임에도 불구하고 공간이 한정된 엔진룸에서 각각 다른 위치에 장착되므로서 차량을 생산하는 조립라인에서 작업성이 곤란할 뿐만 아니라, 인터쿨러와 엔진을 연결하는 파이프나 호스 등의 배치가 복잡해지게 되므로서 엔진룸의 공기흐름에 저항으로 작용되어 차량의 가속응답성 및 출력이 떨어지고 기류음 등이 발생하는 문제점이 있었다.However, although the intercooler and the radiator respectively function to cool the air and the coolant, the intercooler and the radiator are mounted at different positions in the engine room where the space is limited. Since the arrangement of pipes and hoses connecting the engine is complicated, the engine acts as a resistance to the air flow in the engine room, resulting in a drop in acceleration response and output of the vehicle, and airflow.

본 발명은 상기한 문제점을 해결하기 위해서 안출된 것으로서, 보다 상세하게는 엔진의 냉각수를 냉각하기 위해 엔진의 전방에 형성되던 라디에이터와, 터보차저의 성능향상을 위해 엔진룸의 일측에 별도로 형성되던 인터쿨러를 일체화하여 엔진룸의 공간이 효율적으로 활용되도록 하는 인터쿨러와 일체로 형성된 라디에이터를 제공하는 데 목적이 있는 것이다.The present invention has been made to solve the above problems, more specifically, a radiator formed in front of the engine to cool the cooling water of the engine, and an intercooler formed separately on one side of the engine room to improve the performance of the turbocharger It is an object of the present invention to provide a radiator formed integrally with the intercooler to integrate the space so that the space of the engine room is efficiently utilized.
