Description

자동차의 냉각계 배치구조{a cooling system arrangement structure for vehicles}Cooling system arrangement structure for vehicles

본 발명은 자동차의 냉각계 배치구조에 관한 것으로, 특히 엔진의 냉각수를 냉각시키는 라디에이터와 가열된 과급공기를 냉각시키는 인터쿨러의 배치구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling system arrangement of an automobile, and more particularly to an arrangement structure of a radiator for cooling an engine coolant and an intercooler for cooling heated supercharged air.

일반적으로 자동차의 엔진에는 냉각수통로가 형성되어 있으며, 작동에 의해가열된 엔진은 상기 냉각수통로를 흐르는 냉각수에 의하여 냉각되도록 되어 있다.Generally, a cooling water passage is formed in an engine of a vehicle, and an engine heated by the operation is cooled by the cooling water flowing through the cooling water passage.

이와 같은 엔진과의 열교환에 의하여 가열된 냉각수를 다시 식히기 위해서 엔진을 돌아 나온 냉각수는 라디에이터를 거치도록 되어 있으며, 라디에이터를 통과하는 동안 라디에이터를 걸쳐 흐르는 외기에 의해 감온되게 된다.The coolant that exits the engine to cool the heated coolant by heat exchange with the engine passes through a radiator, and is cooled by external air flowing through the radiator while passing through the radiator.

따라서 자동차의 엔진룸 앞쪽 부분에는 라디에이터가 설치되며, 저속운전시 강제적으로 외기를 빨아 들여 라디에이터로의 송풍량을 증가시킴으로써 라디에이터의 냉각성을 향상시키기 위하여 전기모터에 의해 작동되는 냉각팬이 부가적으로 설치된다.Therefore, a radiator is installed in the front part of the engine room of the car, and a cooling fan operated by an electric motor is additionally installed to improve cooling performance of the radiator by forcibly sucking outside air at a low speed driving to increase the airflow to the radiator. .

한편, 엔진으로 공급되는 외기의 흡입효율을 높이기 위하여 배기가스를 이용해 작동되는 과급기가 장착된 차량의 경우에는 과급된 흡입공기가 가열되어 그 밀도가 낮아짐으로써 연소실내 충진효율이 저하되는 것을 방지하기 위해서 과급기와 흡기매니폴드 사이에 인터쿨러가 설치되는데 이 인터쿨러 또한 주행중 외기와의 접촉성 향상을 위하여 엔진룸의 앞쪽에 설치된다.On the other hand, in the case of a vehicle equipped with a supercharger operated using exhaust gas to increase the intake efficiency of the outside air supplied to the engine, in order to prevent the filling efficiency in the combustion chamber from being lowered by lowering its density by heating the supercharged intake air. An intercooler is installed between the supercharger and the intake manifold, which is also installed in front of the engine room to improve contact with the outside air while driving.

즉, 상기 두 냉각장치들이 모두 엔진룸의 앞쪽에 설치됨으로써 양자간의 배치관계에 의한 냉각수와 과급공기의 냉각효율에 관한 문제가 대두되게 되었다.That is, since the two cooling devices are installed in front of the engine room, problems related to the cooling efficiency of the coolant and the charge air due to the arrangement relationship between the two have been raised.

한편, 종래에는 도 1에 도시된 바와 같이, 라디에이터(10)의 뒤쪽에 냉각팬(20)이 설치되고, 인터쿨러(30)는 상기 라디에이터(10)의 앞쪽에 설치되는 형태로 라디에이터(10)와 인터쿨러(30)가 배치되어 있었다.Meanwhile, as shown in FIG. 1, the cooling fan 20 is installed at the rear of the radiator 10, and the intercooler 30 is installed at the front of the radiator 10. The intercooler 30 was arrange | positioned.

그러나, 상기와 같은 종래 구조에서 라디에이터(10)로 불어 오는 외기는 일단 인터쿨러(30)에 접촉하여 가열된 상태이므로 라디에이터(10) 냉각성능이 저하되는 문제점이 있었다.However, in the conventional structure as described above, since the outside air blowing into the radiator 10 is heated in contact with the intercooler 30, there is a problem in that the cooling performance of the radiator 10 is lowered.

이러한 문제점을 해결하기 위하여 라디에이터(10)나 냉각팬(20)의 크기를 크게 하는 것은 엔진룸 레이아웃상 난해한 점이 많고(이들 주변의 각종 커버류의 적용을 폐지하여 설치공간을 확보하려면 소음법규를 위반하게 된다.), 인터쿨러(30)의 크기를 작게 하는 것도 인터쿨러(30)의 최소성능치를 규제하는 법규를 만족시키지 못할 소지가 커서 곤란하였다.In order to solve this problem, increasing the size of the radiator 10 or the cooling fan 20 has many difficulties in the layout of the engine room. In addition, it is difficult to reduce the size of the intercooler 30 because it is difficult to satisfy the legislation regulating the minimum performance value of the intercooler 30.

그렇다고 라디에이터(10)와 인터쿨러(30)의 위치를 바꾸어 인터쿨러(30)의 앞쪽에 라디에이터(10)를 위치시키면 이때는 인터쿨러(30)의 냉각효율이 지나치게 저하되어 결국은 동일한 문제점에 봉착하게 된다.However, if the radiator 10 is positioned in front of the intercooler 30 by changing the positions of the radiator 10 and the intercooler 30, the cooling efficiency of the intercooler 30 is excessively lowered and eventually encounters the same problem.

이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 발명된 것으로, 인터쿨러의 냉각성능을 크게 저하시키지 않으면서도 라디에이터의 냉각성능을 향상시킬 수 있고, 또한 동시에 엔진룸내 다른 장치들과의 레이아웃에 따른 장착상의 난해함을 해결할 수 있도록 된 자동차의 냉각계 배치구조를 제공함에 그 목적이 있다.Therefore, the present invention has been invented to solve the above problems, it is possible to improve the cooling performance of the radiator without significantly lowering the cooling performance of the intercooler, and at the same time it is possible to It is an object of the present invention to provide a cooling system arrangement of a vehicle that can solve the difficulty.

상기와 같은 목적을 달성하기 위한 본 발명은, 인터쿨러의 앞쪽에 인터쿨러의 상부 반을 가리는 크기의 전방 라디에이터가 설치되고, 이 전방 라디에이터의 뒤쪽에 상기 인터쿨러가 설치되며, 이 인터쿨러의 뒤쪽에 인터쿨러의 하부 반 크기에 해당되는 후방 라디에이터가 설치되되 이 후방 라디에이터와 상기 전방 라디에이터는 연결관으로 연결되고, 상기 후방 라디에이터의 뒤쪽에 냉각팬이 설치되는구조로 이루어져 있다.The present invention for achieving the above object, the front radiator of the size that covers the upper half of the intercooler is installed in the front of the intercooler, the intercooler is installed in the rear of the front radiator, the lower part of the intercooler at the rear of the intercooler A rear radiator corresponding to a half size is installed, and the rear radiator and the front radiator are connected by a connecting pipe, and a cooling fan is installed at the rear of the rear radiator.

즉, 라디에이터가 가열되지 않은 외기에 직접 접촉될 수 있으면서도 인터쿨러의 냉각성능이 크게 저하되지 않도록 된 것이다.In other words, while the radiator can be in direct contact with the unheated outside air, the cooling performance of the intercooler is not significantly reduced.

이하, 본 발명을 첨부된 예시도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

도 2는 본 발명에 따른 자동차의 냉각계 배치구조의 측면도로서, 본 발명은 중앙에 인터쿨러(30)가 설치되고, 이 인터쿨러(30)의 앞뒤쪽에 각각 전방 라디에이터(11)와 후방 라디에이터(12)가 설치되며, 이중 후방 라디에이터(12)의 뒤쪽으로 냉각팬(20)이 설치되는 구조로 이루어져 있다.Figure 2 is a side view of the cooling system arrangement of the vehicle according to the present invention, the present invention is provided with an intercooler 30 in the center, the front radiator 11 and the rear radiator 12 in front and rear of the intercooler 30, respectively. Is installed, it consists of a structure in which the cooling fan 20 is installed to the rear of the double rear radiator 12.

여기서, 상기 전방 라디에이터(11)와 후방 라디에이터(12)는 각각 종래 라디에이터의 1/2에 해당하는 크기를 가지고 있으며, 도 3에 도시된 바와 같이 2개의 연결관(13,14)으로 연결되는데, 전방 라디에이터(11)의 입수관(11a)측 부위와 후방 라디에이터(12)의 동일 부분에 하나의 연결관(13)이 연결되고, 후방 라디에이터(12)의 출수관(12a)측 부위와 전방 라디에이터(11)의 동일 부분에 다른 한 연결관(14)이 연결되는 구조로 되어 있다.Here, the front radiator 11 and the rear radiator 12 each have a size corresponding to 1/2 of a conventional radiator, and are connected to two connecting pipes 13 and 14 as shown in FIG. One connection pipe 13 is connected to the same portion of the water inlet pipe 11a side of the front radiator 11 and the rear radiator 12, and the water outlet pipe 12a side of the rear radiator 12 and the front radiator. Another connection pipe 14 is connected to the same part of (11).

즉, 2분할된 라디에이터들의 각 입수측과 출수측이 연결관(13,14)으로 각각 연결된 것이며, 엔진에서 나온 가열된 냉각수는 입수관(11a)을 통하여 전방 라디에이터(11)로 유입됨과 동시에 연결관(13)을 통하여 후방 라디에이터(12)로 유입되며, 전방 라디에이터(11)를 통과하면서 냉각된 냉각수는 입수관(11a)과 대응되는 위치에 연결된 연결관(14)을 통하여 후방 라디에이터(14)의 출수관(12a) 형성부위로 유입된 뒤, 이 출수관(12a)을 통하여 배출되어 다시 관로를 따라 펌프를 거쳐 엔진으로 공급되며, 후방 라디에이터(12)를 통과한 냉각수 역시 이 출수관(12a)을 통해 배출되어 동일한 순환과정을 반복하게 된다.That is, the inlet and outlet sides of the two divided radiators are connected to the connecting pipes 13 and 14, respectively, and the heated coolant from the engine is simultaneously connected to the front radiator 11 through the inlet pipe 11a. Cooling water flowing into the rear radiator 12 through the tube 13 and passing through the front radiator 11 is connected to the rear radiator 14 through a connection pipe 14 connected to a position corresponding to the inlet pipe 11a. After flowing into the forming portion of the outlet pipe 12a of the outlet, it is discharged through the outlet pipe 12a and supplied to the engine via a pump along the pipeline again, and the coolant passing through the rear radiator 12 is also the outlet pipe 12a. Is discharged through) to repeat the same cycle.

따라서, 상기 전방 라디에이터(11)와 후방 라디에이터(12)의 사이 공간에 인터쿨러(30)가 배치되는 본 발명에서는 전방 라디에이터(11)가 인터쿨러(30)에 의해 가열되지 않은 찬 외기를 직접 맞을 수 있게 되므로 라디에이터 전체가 인터쿨러(30)의 후방에 위치한 종래의 경우에 비하여 냉각성능이 향상된다.Accordingly, in the present invention in which the intercooler 30 is disposed in the space between the front radiator 11 and the rear radiator 12, the front radiator 11 may directly hit the cold outside air not heated by the intercooler 30. Therefore, the cooling performance is improved as compared with the conventional case in which the entire radiator is located behind the intercooler 30.

반면, 인터쿨러(30)의 경우 종래에 비하여 전방 상부가 전방 라디에이터(11)에 의해 가려져 냉각작용에 다소 불리한 면은 있으나, 아래쪽 반은 여전히 가열되지 않은 외기에 직접 접촉될 수 있으므로 큰 성능저하는 일어나지 않으며 과급공기 냉각에 대한 엔진 냉각의 중요성을 비교해 볼 때 감수할만한 정도이다.On the other hand, in the case of the intercooler 30, the front upper part is covered by the front radiator 11, which is somewhat disadvantageous to the cooling operation, but the lower half may be directly in contact with the unheated outside air. It is worth noting when comparing the importance of engine cooling to supercharged air cooling.

따라서, 상기 라디에이터들과 인터쿨러가 종래와 동일한 공간내에 설치 가능하므로 엔진룸 내 레이아웃에 따른 곤란함 없이 인터쿨러의 냉각성능을 크게 저하시키지 않으면서도 라디에이터의 냉각성능을 향상시킬 수 있는 냉각계의 배치가 가능하다.Therefore, since the radiators and the intercooler can be installed in the same space as before, the cooling system can be arranged to improve the cooling performance of the radiator without significantly reducing the cooling performance of the intercooler without difficulty in layout of the engine room. Do.

이상 설명한 바와 같이 본 발명에 따르면, 라디에이터를 전방 라디에이터와 후방 라디에이터로 분리하여 각각 인터쿨러의 전방상부와 후방하부에 배치함으로써 양자에 모두 가열되지 않은 찬 외기가 접촉될 수 있게 되므로 인터쿨러의 큰 성능저하 없이 라디에이터의 냉각성능을 향상시킬 수 있게 되는 효과가 있으며, 재배치시 종래와 동일한 공간내에 적용가능하므로 엔진룸내 여타 장치들과의 레이아웃에 따른 문제를 고려하지 않아도 되는 장점이 있다.As described above, according to the present invention, by separating the radiator into a front radiator and a rear radiator and arranged in the front upper part and the rear lower part of the intercooler, respectively, both of them can come into contact with cold outside air that is not heated. There is an effect that can improve the cooling performance of the radiator, there is an advantage that does not have to consider the problem due to the layout with the other devices in the engine room because it can be applied in the same space as the conventional relocation.
