Description

에어 컴프레서 냉각 장치Air compressor cooling system

본 발명은 냉각 장치에 관한 것으로서, 보다 상세하게는 대형 자동차에서 많이 사용되는 에어 컴프레서의 냉각 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling device, and more particularly, to a cooling device of an air compressor that is frequently used in a large vehicle.

일반적으로, 자동차는 엔진, 변속기 등과 같은 기계적인 부품과, 상기한 각 부품을 제어하는 전자적인 부품으로 구분되어 있는 바, 상기한 전자 제어 부품은 일정한 신호를 유체의 압력으로 변환시켜 기계적인 부품들을 제어하게 된다.In general, an automobile is divided into mechanical parts such as an engine and a transmission, and electronic parts for controlling each of the above-mentioned parts. The electronic control parts convert mechanical signals into a fluid pressure to convert mechanical parts. Control.

물론, 상기한 유체의 압력을 발생시키기 위해서는 컴프레서 등과 같은 장치가 필요하게 된다.Of course, a device such as a compressor is required to generate the pressure of the fluid.

특히, 대형차등과 같이 대량의 공압을 사용하는 자동차에서는 대용량의 컴프레서가 필수장착된다.In particular, in a vehicle using a large amount of pneumatics such as a large vehicle, a large capacity compressor is essential.

즉, 클러치 및 브레이크 등의 동작을 보다 용이하고 정확하게 동작시키기 위하여 대형차에서는 공압을 사용하게 되는 것이다.In other words, in order to operate the clutch and the brake more easily and accurately, the large vehicle uses pneumatic pressure.

여기서, 상기한 브레이크 장치는 제3도에 도시한 바와 같이 브레이크 밸브(50)와, 상기한 브레이크 밸브(50)에 릴레이 밸브(51)를 개재한 상태로 연결된 전, 후륜 브레이크(52,53)와, 상기한 전, 후륜 브레이크(52,53)에 공압을 인가하기 위하여 연결 설치된 컴프레서(54) 및 전,후륜 리저버(55,56)로 구성되어 있다.Here, as shown in FIG. 3, the brake device includes front and rear brakes 52 and 53 connected to the brake valve 50 and the brake valve 50 with the relay valve 51 interposed therebetween. And a compressor 54 connected to the front and rear wheel brakes 52 and 53 and a front and rear wheel reservoirs 55 and 56 that are connected to each other.

특히, 상기한 컴프레서(54)는 고속 회전되는 부품이기 때문에 과열을 방지하기 위하여 라디에이터(57)를 통과한 냉각수가 이를 냉각시킬 수 있도록 연결되어 있다.In particular, since the compressor 54 is a component that is rotated at a high speed, the coolant passing through the radiator 57 is connected to cool it in order to prevent overheating.

상기한 브레이크 장치는 엔진 시동과 동시에 컴프레서(54)가 동작되면서 압축 공기를 전, 후륜 리저버(55,56)에 저장하게 되고, 상기한 브레이크 밸브(50)를 동작시키게 되면 상기한 리저버(55,56)에서 고압 공기가 각 브레이크(52,53)로 전달되면서 제동 작용을 수행하게 되는 것이다.The brake device stores the compressed air in the front and rear wheel reservoirs 55 and 56 while the compressor 54 is operated at the same time as the engine starts, and when the brake valve 50 is operated, the reservoir 55 is operated. At 56, high pressure air is delivered to each of the brakes 52 and 53 to perform a braking action.

물론, 상기한 컴프레서(54)는 냉각수에 의해 냉각됨으로써 과열을 방지하게 된다.Of course, the compressor 54 is cooled by the cooling water to prevent overheating.

그러나, 상기한 바와 같이 라디에이터를 통해 토출된 냉각수로 컴프레서를 냉각하게 되면 냉각수의 온도가 약 90~95℃ 정도가 되기 때문에 충분한 냉각이 이루어지지 않게 되고, 이로 인해 컴프레서의 마모가 촉진되는 문제점이 있다.However, when the compressor is cooled by the cooling water discharged through the radiator as described above, since the temperature of the cooling water is about 90 to 95 ° C., there is a problem in that the cooling of the compressor is not performed. .

따라서, 본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 컴프레서의 냉각 효율을 향상시켜 수명을 향상시킬 수 있는 에어 컴프레서의 냉각 장치를 제공함에 있다.Accordingly, an object of the present invention is to provide a cooling device for an air compressor that can improve the cooling efficiency of the compressor by improving the cooling efficiency of the compressor.

상기한 목적을 실현하기 위하여 본 발명은 자동차에 설치된 에어컨의 냉기가 에어 컴프레서를 냉각시키기 위하여 순환되는 냉각수를 냉각시킬 수 있도록 형성된 냉각 수단으로 구성함을 특징으로 한다.In order to achieve the above object, the present invention is characterized in that the cooling means of the air conditioner installed in the vehicle is configured to cool the cooling water circulated to cool the air compressor.

제1도는 본 발명에 따른 에어 컴프레서 냉각 장치를 도시한 개략도로서, 자동차에 설치된 에어컨(A)의 냉기가 에어 컴프레서(54)로 인입되는 냉각수를 냉각시킬 수 있도록 냉각수를 냉각시킬 수 있도록 냉각 수단이 설치되어 있다.1 is a schematic view showing an air compressor cooling apparatus according to the present invention, wherein the cooling means is configured to cool the cooling water so that the cold air of the air conditioner A installed in the vehicle cools the cooling water introduced into the air compressor 54. It is installed.

상기한 냉각 수단은 제2도에 도시된 바와 같이 냉각수가 이동하는 배관(L)의 일부분에 형성된 핀(1)과, 상기한 핀(1)을 감쌀 뿐만 아니라 일정한 공간을 형성하고 입구(2)와 출구(3)가 형성된 냉각 챔버(4)로 구성되어 있다.As shown in FIG. 2, the cooling means includes a fin 1 formed at a portion of a pipe L through which the coolant moves, and not only surrounds the fin 1 but also forms a constant space and forms an inlet 2. And the cooling chamber 4 in which the outlet 3 was formed.

즉, 자동차의 에어컨(A)이 동작되면 증발기(E)를 통과한 공기가 냉각된 상태로 냉각 챔버(4)를 통과하면서 상기한 배관(L)을 통해 이동하는 냉각수를 냉각시켜 컴프레서(54)의 냉각 효율을 향상시키게 되는 것이다.That is, when the air conditioner A of the vehicle is operated, the air passing through the evaporator E is cooled while passing through the cooling chamber 4 while cooling the cooling water moving through the pipe L and the compressor 54. It is to improve the cooling efficiency of.

물론, 에어컨(A)을 동작시키지 않을 때에는 블로워(B)만 동작시킴으로써 바람에 의해 냉각수를 냉각시키게 된다.Of course, when the air conditioner A is not operated, only the blower B is operated to cool the cooling water by wind.

상기한 바와 같은 본 발명의 작용 효과를 설명하면 자동차의 주행중 에어컨(A)을 동작시키게 되면 상기한 에어컨(A)의 증발기기(E)를 통과한 찬 공기가 냉각 챔버(4)의 입구(2)를 통해 인입된다.Referring to the operation and effect of the present invention as described above when operating the air conditioner (A) while driving of the car cold air passing through the evaporator (E) of the air conditioner (A) is the inlet (2) of the cooling chamber (4) Is imported through).

찬 공기가 냉각 챔버(4)의 내부로 인입되면 배관(L) 및 핀(1)을 통해 열 교환이 이루어지면서 이를 통과하는 냉각수를 냉각시키게 된다.When cold air is introduced into the cooling chamber 4, heat is exchanged through the pipe L and the fin 1 to cool the cooling water passing therethrough.

물론, 상기한 냉각 챔버(4)가 감싸는 배관(L)의 길이는 냉각수의 냉각 온도가 소정 상태가 되도록 적절하게 조절하게 된다.Of course, the length of the pipe (L) surrounding the cooling chamber 4 is appropriately adjusted so that the cooling temperature of the cooling water is a predetermined state.

여기서, 상기한 냉각 챔버(4)를 사용하지 않고 핀(1)만 형성된 배관(L)을 찬 공기에 노출시켜도 소정의 냉각 효과가 이루어지게 되지만 냉각 효율을 향상시키기 위하여 찬 공기가 배관(L) 위치에 잔류할 수 있도록 냉각 챔버(4)를 설치하게 된다.Here, even if the pipe (L) formed only the fin (1) without using the cooling chamber (4) is exposed to the cold air, a predetermined cooling effect is achieved, but the cold air is pipe (L) to improve the cooling efficiency The cooling chamber 4 is installed so that it can remain in position.

냉각수가 냉각 챔버(4) 설치 위치를 통과하게 되면 소정 온도 낮아지게 되는 바, 상기한 냉각수가 컴프레서(54)를 냉각시킴으로써 컴프레서(54)의 과열을 방지할 수 있게 된다.When the cooling water passes through the installation position of the cooling chamber 4, the predetermined temperature is lowered. Thus, the cooling water cools the compressor 54, thereby preventing overheating of the compressor 54.

이상과 같이 본 발명은 에어컨의 찬 공기가 에어 컴프레서를 냉각시키는 냉각수를 냉각시키도록 함으로써 별도의 냉각 장치를 설치하지 않고도 에어 컴프레서의 과열을 방지할 수 있는 잇점이 있는 것이다.As described above, the present invention has the advantage that the cold air of the air conditioner cools the cooling water for cooling the air compressor, thereby preventing overheating of the air compressor without installing a separate cooling device.
