Description

오일쿨러 {OIL COOLER}Oil Cooler {OIL COOLER}

본 발명은 차량에 구비되는 오일의 온도를 낮추어 점도를 유지하도록 하는 오일쿨러에 있어서, 상기 오일쿨러를 플레이트 형태로 구성하여 적층하도록 하고, 상기 적층되는 플레이트의 냉각수유로들의 사이와 오일유로들의 사이에는 냉각수와 오일이 플레이트의 전체면적으로 이동할 수 있도록 흐름패턴을 개선하므로써 오일쿨러 전체의 부피를 줄이면서 열효율을 향상시키고 쿨링에 따른 순환을 원활하게 할 수 있도록 한 오일쿨러에 관한 것이다.The present invention is an oil cooler to maintain the viscosity by lowering the temperature of the oil provided in the vehicle, the oil cooler in the form of a plate to be laminated, and between the cooling water passages of the laminated plate and between the oil passages The present invention relates to an oil cooler that improves thermal efficiency and improves circulation according to cooling by reducing the volume of the entire oil cooler by improving the flow pattern so that the coolant and the oil can move to the entire area of the plate.

일반적으로 차량의 엔진등에는 차량의 엔진윤활을 위하여 오일을 엔진에 공급하고 있으며, 상기 오일은 엔진의 실린더내부를 따라 순환하면서 기밀작용과 윤활작용 및 냉각작용을 하도록 되어 있고, 상기 실린더를 따라 순환하면서 냉각작용을하여 엔진을 식히게 되므로써 상기 오일이 열화가 되고 있었다.In general, the engine of the vehicle supplies oil to the engine for engine lubrication of the vehicle, and the oil circulates along the inside of the cylinder to perform airtight, lubricating and cooling operations, and circulates along the cylinder. The oil deteriorated by cooling the engine while cooling.

따라서, 상기 오일이 열화될 경우에는 그 점도가 심하게 손상되어 오일의 기능을 하지 못하게 되는 폐단이 있었기 때문에 상기 오일을 냉각시킬 수 있는 오일쿨러를 필요로 하게 되었다.Therefore, when the oil is deteriorated, since the viscosity is severely damaged and there is a closed end that does not function as an oil, an oil cooler capable of cooling the oil is required.

한편, 상기와 같은 오일쿨러는 일반적인 공기조화기기 등의 열교환기에서와 같이 압축된 냉매를 응축하고 이 응축되는 냉매를 증발시키면서 순환함에 따라 오일을 냉각시키도록 구성되어 있었으며, 상기 오일쿨러에는 냉각수를 쿨링시킬 수 있는 냉각수 쿨러를 병행하여 구성하고 상기 쿨러의 방열부를 2열로 나누어 각 방열부의 사이 사이에 냉각수와 오일이 순환하면서 냉각되도록 구성되어 있었다.On the other hand, the oil cooler as described above was configured to cool the oil as it condenses the compressed refrigerant and circulates while evaporating the condensed refrigerant, as in a heat exchanger such as a general air conditioner, the cooler The cooling water cooler capable of cooling was configured in parallel, and the heat dissipation portion of the cooler was divided into two rows so as to cool the water and the oil while circulating between the heat dissipation portions.

상기와 같이 구성되는 종래의 오일쿨러에 있어서는 도 1에서와 같이 냉각수용과 오일용의 방열부를 구비하기 위하여 플레이트 형상으로 이루어진 방열부를 적층형으로 구성하고 이 적층형의 플레이트(101)(102)들에는 각각의 냉각수용 방열부(103)와 오일용 방열부(104)를 각각 형성하며, 이 방열부(103)(104)들에는 냉각수와 오일이 흐르는 유로(105)(106)를 각각 형성하도록 구성되어 있었다.In the conventional oil cooler configured as described above, as shown in FIG. 1, the heat dissipation unit having a plate shape is formed in a stack type in order to have a heat dissipation unit for cooling water and oil, and each of the stacked plates 101 and 102 has respective cooling. The accommodating heat dissipation part 103 and the oil heat dissipation part 104 were formed, respectively, and these heat dissipation parts 103 and 104 were configured to form flow paths 105 and 106 through which coolant and oil flow, respectively.

또, 상기 각 유로(105)(106)들은 각각의 방열부(103)(104)와는 연결되지만, 타 방열부와는 격리되어 상기 냉각수와 오일이 서로 섞이지 않도록 구성되어 있었다.In addition, each of the flow paths 105 and 106 is connected to each of the heat dissipating parts 103 and 104, but is isolated from the other heat dissipating parts so that the cooling water and the oil do not mix with each other.

그러나, 상기와 같은 종래의 것은 상기 방열부들의 내부와 유통되는 유로들의 구조가 대체로 대각으로 연결되어 수직으로 흐르거나 수평상태로 연결되어 있기 때문에 상기 대각상태의 유로를 따라 흐르는 일의 연결부위에서만 열교환 작용이 이루어지고 있으며, 상기 연결되는 대각부분을 제외하고는 다른 부분에서 오일의 흐름작용이 이루어지지 못하게 되고 이에 따라 열교환 면적이 작게 되므로서 열교환 효율이 극히 저하되는 폐단이 있었으며, 냉각수의 흐름에 있어서도 유입부와 유출구가 근접되어 있어 이들의 위치에서만 냉각수가 흐르게 되고 후미쪽에서는 흐름이 거의 없기 때문에 냉각수의 흐름면적 보다 사각면적이 많게 되어 부피를 줄이는 효과를 발휘하지 못하고, 효과적인 쿨링작용이 이루어지지 못하는 점등의 문제점이 있었다.However, since the structure of the flow paths circulating in the interior of the heat dissipating portion is generally diagonally connected and flows vertically or horizontally, the heat exchange is performed only at the connection part of the work flowing along the diagonal flow path. There is a closed end where the flow of oil cannot be made in other parts except for the diagonal portion connected to each other, and thus the heat exchange area is reduced, and the heat exchange efficiency is extremely reduced. Since the inlet and outlet are close, the coolant flows only at their positions, and there is almost no flow at the rear side, so the dead area is larger than the flow area of the coolant, resulting in no volume reduction effect, and no effective cooling effect. There was a problem of lighting.

본 발명은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로 본 발명은 차량에 구비되는 오일의 온도를 낮추어 점도를 유지하도록 하는 오일쿨러에 있어서, 상기 오일쿨러를 플레이트 형태로 구성하여 적층하도록 하고, 상기 적층되는 플레이트의 냉각수유로들의 사이와 오일유로들의 사이에는 냉각수와 오일이 플레이트의 전체면적으로 이동할 수 있도록 수평과 수직의 흐름패턴을 개선하므로써 오일쿨러 전체의 부피를 줄이면서 열효율을 향상시키고 쿨링에 따른 순환을 원활하게 할 수 있도록 한 오일쿨러를 제공하려는 것인바, 이를 이하에서 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-described conventional problems, the present invention is to reduce the temperature of the oil provided in the vehicle in the oil cooler to maintain the viscosity, the oil cooler in the form of a plate to be laminated In order to improve the thermal efficiency and cooling while reducing the volume of the entire oil cooler by improving the horizontal and vertical flow patterns between the cooling water flow paths and the oil flow paths of the stacked plates so that the coolant and the oil can move to the entire area of the plate. It is to provide an oil cooler to facilitate the circulation according to the bar, which will be described in detail based on the accompanying drawings as follows.
