본 고안은 자동차용 오일쿨러에 관한 것으로서 더욱 상세하게는 오일의 냉각효율을 증대시킬 수 있도록 한 것이다.The present invention relates to an automotive oil cooler, and more particularly, to increase the cooling efficiency of oil.
자동차용 오일쿨러는 엔진에 주입되어 엔진의 윤활은 물론 엔진 각부분의 냉각, 청소, 방청 및 연소실 내에서의 가스가 누출되는 것을 방지하기 위하여 사용되는 엔진오일이나 기타 미션오일등을 냉각시켜주는 장치이다.Automotive oil cooler is injected into the engine to cool the engine oil or other mission oil used to lubricate the engine as well as to prevent leakage of gas from the cooling, cleaning, rust prevention and combustion chambers of the engine parts. to be.
자동차용 엔진오일은 온도가 125 - 130℃이상이 될 경우에는 오일의 성능이 급격히 저하되며, 이때에는 오일의 유막이 형성되지 않으므로 인하여 습동부분이 소결되는 현상이 일어난다.When the temperature of the engine oil for cars is 125-130 ℃ or more, the performance of the oil is sharply lowered, and at this time, the oil film is not formed, the sliding part is sintered due to the phenomenon.
그러므로 자동차의 엔진내에 주입된 오일의 온도는 70 - 80℃의 온도를 유지하는 것이 엔진의 윤활작용은 물론 기타 각 부품의 소결을 방지하는 등의 역할을 수행할 수 있게 되는 것이다.Therefore, maintaining the temperature of the oil injected into the engine of the automobile 70 to 80 ℃ can play a role of preventing the lubrication of the engine as well as the sintering of each other parts.
이러한 엔진오일의 온도를 일정하게 유지할 수 있도록 하기 위하여 사용하는 것이 오일쿨러이며, 종래기술의 오일쿨러가 제 1 도내지 제 2 도에 걸쳐 도시되어 있으며 이를 상세하게 살펴보면 다음과 같다.The oil cooler is used to maintain the temperature of the engine oil in a constant manner, and the oil cooler of the prior art is illustrated in FIGS. 1 to 2, and the details are as follows.
라디에이터의 내부에 설치되는 종래의 오일쿨러(1)는 이중관을 이용하여 중앙에는 냉각수가 유동할 수 있는 냉각수로(2)를 가지고, 상기 냉각수로(2)의 외주연에는 오일이 유동할 수 있는 오일관로(3)를 가지게 되며 상기 오일관로(3)에는 오일인렛(4)과 아웃렛(5)을 구비하고 있는 구조이다.The conventional oil cooler 1 installed inside the radiator has a cooling water passage 2 through which a cooling water can flow in the center by using a double pipe, and oil can flow in the outer circumference of the cooling water passage 2. The oil pipeline 3 has an oil inlet 4 and an outlet 5 in the oil pipeline 3.
이러한 종래의 기술은 엔진오일은 횡방향으로 유동이 되고 냉각수는 냉각수로(2)와 오일관로(3)의 외측으로 오일의 유동과는 반대방향으로 흐르면서 엔진오일의 열원을 빼앗아 냉각시켜주도록 하고 있다.This conventional technology allows the engine oil to flow in the transverse direction, and the coolant takes away the heat source of the engine oil while flowing in the direction opposite to the flow of oil to the outside of the cooling water passage (2) and the oil pipeline (3). .
때문에, 냉각수가 오일관로(3)를 통하여 유동하는 엔진오일의 열원을 빼앗는데 필요한 접촉면적이 작아 오일의 냉각이 실질적으로 상당한 어려움을 가지고 있어 냉각성능이 저하되는 등의 어려움이 있었다.Therefore, the contact area necessary for the cooling water to take away the heat source of the engine oil flowing through the oil pipeline 3 is small, the cooling of the oil has a substantial difficulty, there is a difficulty in lowering the cooling performance.
근자에 들면서는 나선관을 이용하여 오일관로를 구성하는 방식의 오일쿨러도 제공되고 있으나 나선관이 동재질로 이루어지고 나선관의 내부에 별도의 매개체를 삽입하여야하므로 제작에 있어 상당한 난점을 가지게 됨은 물론, 구조도 복잡하여지는 등의 문제점들이 있었다.In recent years, oil coolers are also provided in which oil pipelines are constructed using spiral pipes. However, since the spiral pipe is made of the same material and a separate medium must be inserted into the spiral pipe, it has a considerable difficulty in manufacturing. Of course, there were problems such as complicated structure.
이에 본 고안에서는 상기한 문제점들을 해결하기 위하여 안출이 된 것으로서 특히 나선관을 이용하는 방식의 오일쿨러를 더욱 개선하여 열교환이 보다 원활하게 이루어질 수 있도록 하면서도 제작이나 조립에 어려움이 없도록 한 것이 특징이다.Therefore, the present invention has been devised to solve the above problems, and in particular, the oil cooler using a spiral tube is further improved, so that heat exchange can be made more smoothly, but there is no difficulty in manufacturing or assembling.
이하 첨부되는 도면과 관련하여 본 고안의 구성과 작용 및 효과에 대하여 설명을 하면 다음과 같다.Hereinafter, the configuration, operation and effects of the present invention will be described with reference to the accompanying drawings.
제 3 도는 본 고안의 기술이 적용된 오일쿨러의 사시도, 제 4 도는 본 고안의 요부인 나선관을 발췌한 사시도, 제 5 도는 제 4 도의 A - A선 단면도로서 함께 설명을 한다.FIG. 3 is a perspective view of an oil cooler to which the technique of the present invention is applied, FIG. 4 is a perspective view of a spiral tube which is a main part of the present invention, and FIG. 5 is a cross-sectional view taken along line A-A of FIG.
상방에 오일인렛(10)과 아웃렛(11)을 가지는 집유탱크(12,13)를 가지고 상기 집유탱크(12,13)상간을 나선관(14)으로 연결하여 오일을 나선관(14)으로 유동시켜 냉각토록 한 오일쿨러(20)에 있어서;With oil tanks 12 and 13 having an oil inlet 10 and an outlet 11 upward, the oil tanks 12 and 13 are connected to the spiral pipe 14 to flow oil into the spiral pipe 14. In the oil cooler 20 to be cooled;
상기 집유탱크(12)와 집유탱크(13)상간을 연결하여 오일관로 이용되는 나선관(14)을 알미늄재질로 구성하여 제작 및 조립이 용이함은 물론 열교환이 원활하게 이루어질 수 있도록 한 것이다.The collection tank 12 and the collection tank 13 are connected to each other so that the spiral pipe 14 used as an oil pipe is made of aluminum to facilitate the manufacture and assembly, as well as to facilitate heat exchange.
즉, 내부에 다수개의 냉각핀(20,21)을 일체로 형성시켜 압출한 파이프를 나선형으로 절곡하여 나선관(14)을 구성한 것이다.That is, the spiral pipe 14 is formed by spirally bending the extruded pipe by integrally forming a plurality of cooling fins 20 and 21 therein.
상기 나선관(14)의 내부에 일체로 형성되는 냉각핀(20,21)은 등간격으로 방사형태가 되도록 배열하되, 대냉각핀(20)의 사이 사이에 소냉각핀(21)을 배열하여 구성하는 것이 냉각의 효율성을 높일 수 있다.The cooling fins 20 and 21 integrally formed inside the spiral tube 14 are arranged to be radial at equal intervals, and the small cooling fins 21 are arranged between the large cooling fins 20. Configuration can increase the efficiency of cooling.
상기와 같이 구성된 본 고안은 냉각을 요하는 오일이 인렛(10)을 통하여 유입되어 집수탱크(12)를 거쳐 나선관(14)을 통하여 유동하게 된다.According to the present invention configured as described above, oil requiring cooling is introduced through the inlet 10 and flows through the spiral tube 14 through the collecting tank 12.
이때, 오일쿨러(20)가 냉각수와 직접 접촉이 된 상태에 있으므로 오일과 냉각수가 접촉하는 면적이 넓어지므로서 냉각성이 좋아지게되고, 나선관(14)의 내부에 일체로 형성한 대소의 냉각핀(20,21)에 의하여 오일이 유동하는 도중에 냉각수와의 대류현상이 활발하게 일어나 상재적으로 많은 열교환이 일어나게 되므로 오일의 냉각이 활발하게 이루어진 것이다.At this time, since the oil cooler 20 is in direct contact with the coolant, the area where the oil and the coolant contact each other becomes wider, and thus the cooling performance is improved, and the cooling fins of the small and large are formed integrally inside the spiral tube 14. During the flow of the oil by (20, 21), convection with the coolant is actively generated, so that a lot of heat exchange occurs in the air, and thus the oil is actively cooled.
이상과 같은 본 고안은 내부에 다수개의 냉각핀을 가지는 나선관에 의하여 보다 넓은 접촉에 의하여 오일과 냉각수 상간의 열교환이 이루어져 보다 효율적인 냉각을 할 수 있으므로 오일쿨링의 향상을 가져오는 등의 효과를 가진다.The present invention as described above has a heat exchange between the oil and the coolant phase by a wider contact by a spiral tube having a plurality of cooling fins therein, so that more efficient cooling can be achieved, resulting in improved oil cooling. .
