Description
본 고안은 엔진의 오일쿨러에 관한 것으로서, 보다 상세하게는 오일쿨러의 냉각튜브에 관한 것이다.The present invention relates to an oil cooler of an engine, and more particularly to a cooling tube of an oil cooler.
일반적으로 엔진은 실린더 블록의 보어와 실린더 헤드 및 상기 보어 내에서 왕복 운동하는 피스톤의 사이에 형성되는 연소실에서 연료를 연소시켜 발생된 폭발력을 상기 피스톤에 연결된 커넥팅 로드를 통해 크랭크 샤프트를 회전시킴으로서 열에너지를 기계적인 회전력으로 변환하는 장치이다.In general, the engine generates heat energy by rotating the crankshaft through a connecting rod connected to the piston to explode force generated by burning fuel in a combustion chamber formed between the bore of the cylinder block and the cylinder head and the piston reciprocating within the bore. It is a device that converts into mechanical rotational force.
상기와 같은 엔진의 각 운동 부분에는 각종의 마찰을 해소하기 위해 오일을 통한 윤활 작용이 요구되는 바, 상기와 같은 윤활 작용을 하는 윤활 장치는 주로 캠축이나 크랭크 샤프트에 의해 구동되는 오일 펌프에 의해 오일팬에 저장된 오일을 각 윤활부로 보내게 된다.Each moving part of the engine requires a lubrication action through oil in order to solve various frictions. The lubricating device performing the lubrication action is mainly driven by an oil pump driven by a camshaft or a crankshaft. The oil stored in the pan is sent to each lubrication unit.
또한, 상기와 같이 각 윤활부에 공급되는 오일은 운동부위의 마찰을 줄이는 것 이외에 각 운동부위에서 발생되는 열을 흡수하여 외부로 전달하는 냉각작용도 겸하게 되므로, 상기와 같이 엔진의 각 부위를 순환한 오일은 적절히 냉각되어야 한다.In addition, as described above, the oil supplied to each lubrication part also reduces the friction of the moving parts, and also serves as a cooling function that absorbs heat generated from each moving part and transfers them to the outside, thereby circulating each part of the engine as described above. One oil must be cooled properly.
특히, 상기와 같은 오일은 온도가 125 ~ 130℃ 이상이 되면 성능이 급격히 저하되어 유막의 형성이 나빠지므로, 상기와 같이 엔진의 각 부위에 윤활 및 냉각작용을 병행하는 오일은 70 ~ 80℃정도로 온도가 감소될 수 있도록 별도의 오일쿨러를 설치하는 경우가 있다.In particular, the oil as described above is a temperature of 125 ~ 130 ℃ or more, the performance is sharply degraded, the formation of the oil film worsens, as described above, the oil to lubricate and cool the respective parts of the engine at about 70 ~ 80 ℃ Some oil coolers may be installed to reduce the temperature.
상기한 바와 같은 오일쿨러는 수냉식과 공냉식이 있는 바, 도 1에 도시된 공냉식 오일쿨러는 오일 유입구(50)와 오일 유출구(51)가 마련되고, 상기 오일 유입구(50)와 오일 유출구(51)를 연결하며 통과하는 공기에 의해 오일의 열을 공기에 전달하는 냉각튜브(52)와, 상기 냉각튜브(52)의 방열성능 향상을 위한 핀(fin)(53)으로 구성되어 있다.The oil cooler as described above has a water-cooled and air-cooled bar, the air-cooled oil cooler shown in Figure 1 is provided with an oil inlet 50 and the oil outlet 51, the oil inlet 50 and the oil outlet 51 It consists of a cooling tube 52 for transferring the heat of oil to the air by the air passing through the connection, and a fin (53) for improving the heat dissipation performance of the cooling tube (52).
그런데, 상기와 같이 종래에 사용되고 있는 오일쿨러의 냉각튜브(52)는 그 단면 구조가 도 2에 도시된 바와 같이 일정한 형태의 단면모양을 하고 있어 오일의 흐름은 용이하지만, 흐르는 오일이 층류유동을 하기 쉽게 되어 있어 오일의 방열작용이 용이하게 일어나지 못하는 문제점이 있다.By the way, as described above, the cooling tube 52 of the oil cooler conventionally used has a certain cross-sectional shape as shown in FIG. 2, so that the flow of oil is easy, but the flowing oil is used for laminar flow. There is a problem that the heat radiation action of the oil is not easy to occur easily.
따라서, 본 고안은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 통과되는 오일의 흐름이 난류유동이 될 수 있도록 냉각튜브의 형상을 변경하여 오일의 방열작용이 더욱 원활히 일어나도록 한 엔진의 오일쿨러를 제공함에 그 목적이 있다.Therefore, the present invention has been devised to solve the problems as described above, the oil of the engine to change the shape of the cooling tube so that the flow of oil is turbulent flow flow more smoothly heat dissipation action of the oil occurs The purpose is to provide a cooler.

상기한 바와 같은 목적을 달성하기 위한 본 고안에 따른 엔진의 오일쿨러는 오일이 통과하는 냉각튜브에 다수의 요철부가 형성된 것을 특징으로 한다.The oil cooler of the engine according to the present invention for achieving the object as described above is characterized in that a plurality of irregularities formed in the cooling tube through which the oil passes.
이하, 첨부된 도면을 참조하여 본 고안의 실시 예를 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention.
도 3은 본 고안에 따른 엔진의 오일쿨러에 사용되는 냉각튜브를 도시한 것으로서, 오일이 통과하는 냉각튜브(1)에 냉각튜브(1)의 내측과 외측으로 돌출 및 함몰되는 다수의 요철부(2)가 형성되어 있다.Figure 3 shows a cooling tube used in the oil cooler of the engine according to the present invention, a plurality of uneven parts projecting and recessed in and out of the cooling tube (1) to the cooling tube (1) through which the oil ( 2) is formed.
즉, 냉각되기 위해 통과되는 오일의 흐름에 장애가 되는 요철부(2)를 냉각튜브(1) 자체에 다수 형성한 것이다.That is, a plurality of uneven parts 2 which are obstructed in the flow of oil to be cooled are formed in the cooling tube 1 itself.
상기한 바와 같이 구성된 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.
엔진의 각 운동부위를 순환하면서 윤활 및 냉각작용을 하면서 많은 열을 함유한 상태로 오일쿨러로 유입되는 오일은 상기한 바와 같은 냉각튜브(1)를 통과하면서 냉각이 실시된다.The oil flowing into the oil cooler while lubricating and cooling the engine while circulating each moving part and containing a lot of heat is cooled while passing through the cooling tube 1 as described above.
이때, 상기와 같이 다수의 요철부(2)가 형성된 냉각튜브(1)를 통과하는 오일은 상기 요철부(2)에 의해 그 흐름에 장애를 받게되어 안정된 층류유동을 형성하지 못하고 난류 유동으로 그 유동형태가 변경되면서 오일이 가지고 있는 열을 골고루 냉각튜브(1)에 전달할 수 있게된다.At this time, the oil passing through the cooling tube (1) formed with a plurality of uneven parts (2) as described above is impeded to the flow by the uneven parts (2) does not form a stable laminar flow flow into the turbulent flow As the flow pattern is changed, it is possible to evenly transfer the heat of the oil to the cooling tube (1).
또한, 상기와 같이 마련된 냉각튜브(1)의 요철부(2)는 냉각튜브(1)의 내측면에서는 흐르는 오일로부터 열을 흡수할 수 있는 흡열면적이 확대되는 효과를 내게됨과 동시에 냉각튜브(1)의 외측면에서는 흡수한 열을 외부로 발산하기 위한 방열면적이 더욱 확대되는 효과를 내게된다.In addition, the concave-convex portion 2 of the cooling tube 1 provided as described above has the effect of expanding the heat absorbing area that can absorb heat from the flowing oil on the inner surface of the cooling tube 1 and at the same time cooling tube 1 In the outer surface of the), the heat dissipation area for dissipating the absorbed heat to the outside is further increased.
따라서, 상기와 같이 다수의 요철부가 형성된 냉각튜브는 통과하는 오일의 난류유동을 유도하여 열의 발산을 돕고, 아울러 확대된 흡열면적 및 방열면적을 확보하여 더욱 원활한 오일냉각작용을 수행할 수 있는 효과가 있다.Therefore, the cooling tube formed with a plurality of uneven parts as described above induces turbulent flow of the oil passing therethrough to help dissipate heat, and also has an effect of performing a smoother oil cooling action by securing an enlarged endothermic area and heat dissipation area. have.
