Description

자동차용 오일쿨러{Oil Cooler for automobile} Oil Cooler for automobile}

본 발명은 자동차용 오일쿨러에 관한 것으로서 보다 상세히는 엔진의 오일이 오일쿨러의 쿨링핀을 거치면서 유로저항으로 인해 압력이 낮아지더라도 오일펌프의 용량을 증대시키지 않고서도 엔진의 각 부위에 적정량의 오일을 공급할 수 있도록 하므로서 쿨링핀이나 튜브플레이트에 크랙이 발생되는 것을 방지하여 엔진의 각 부위에 최상의 오일을 공급할 수 있도록 한 자동차용 오일쿨러에 관한 것이다.The present invention relates to an oil cooler for an automobile, and more particularly, to an oil cooler for an automobile, and more particularly, to an oil cooler for an automobile, which is capable of reducing the pressure of the oil cooler through the cooling pin of the oil cooler, The present invention relates to an oil cooler for an automobile, which can supply oil to each part of an engine by preventing cracks from being generated in a cooling fin or a tube plate.

일반적으로 자동차의 엔진을 구성하는 여러부분들에서는 엔진의 작동중에 마찰이 발생하는데 각 마찰요소의 원활한 작동과 밀봉및 냉각을 위해서는 지속적으로 윤활유를 공급해줄 필요가 있어 오일펌프를 작동시켜 엔진의 각 부분으로 윤활용 오일을 공급하게 된다.Generally, in various parts of an automobile engine, friction occurs during operation of the engine. For smooth operation of each friction element, sealing and cooling, it is necessary to continuously supply lubricating oil. So that the lubricating oil is supplied.

그런데 엔진의 여러부분에서 발생되는 고온의 열에 의해 윤활용오일의 온도가 점차 상승하고 점도가 저하되므로써 윤활유로서의 기능을 상실하게 되므로 윤활유 오일을 지속적으로 냉각시켜 주어야 한다.However, since the temperature of the lubricating oil gradually increases due to the high temperature generated in various parts of the engine and the viscosity is lowered, the function as lubricating oil is lost, so the lubricating oil must be continuously cooled.

이처럼 윤활용 오일을 냉각시켜 주기 위하여 사용하는 것이 오일쿨러인데 오 일쿨러는 냉각방식에 따라 공랭식과 수냉식으로 나누어진다.The oil cooler is used to cool the lubricating oil. The oil cooler is divided into air cooling type and water cooling type according to the cooling type.

수냉식 오일쿨러에서는 라디에이터에서 냉각수를 공급받아 엔진오일을 냉각시켜준다.In the water-cooled oil cooler, cooling water is supplied from the radiator to cool the engine oil.

즉, 도1내지 도2에서 도시한 바와같이 종래 수냉식 오일쿨러에서는 쿨링핀(30)이 오일용과 냉각수용으로 구분되어 구비된 다수의 튜브플레이트(20)가 쿨러로워플레이트(10)와 쿨러어퍼플레이트(50) 사이에 적층되어 설치되고, 사방의 입ㆍ출구측 오일챔버(21a)(21b)와 입ㆍ출구측 냉각수챔버 (도면중 미도시)가 서로 격리되어 형성되어 있어 오일이 입구측 오일챔버(21a)를 통해 오일쿨러내로 들어간후 냉각수가 들어있는 쿨링핀(30)을 거치면서 냉각된후 출구측 오일챔버(21b)를 통해 빠져나가 엔진의 각부위로 공급된다.1 and 2, in the conventional water-cooled oil cooler, a plurality of tube plates 20, each having a cooling fin 30 divided into an oil chamber and a cooling chamber, are disposed between the cooler plate 10 and the cooler upper plate Outlet side oil chambers 21a and 21b and the inlet / outlet side cooling water chambers (not shown in the figure) are formed so as to be separated from each other, so that the oil flows into the inlet- Cooled by passing through a cooling fin 30 containing cooling water, and then is discharged through the outlet-side oil chamber 21b and supplied onto the respective portions of the engine.

그런데 날로 엔진의 토크가 증대됨에 따라 엔진 연소시 발생되는 연소열에 의해 엔진오일 온도는 점차 증가하게 되는데 이를 효율적으로 냉각시켜 주기 위해서는 오일쿨러의 용량이 증대되어야 하나 엔진룸내에서의 한정된 공간에서 오일쿨러를 일정크기이상 증대시키지 못하는 것이다.However, as the engine torque increases, the engine oil temperature gradually increases due to the combustion heat generated in the engine combustion. To efficiently cool the engine oil, the capacity of the oil cooler must be increased. However, in the limited space in the engine room, It can not be increased beyond a certain size.

즉, 오일은 오일쿨러의 입구측 오일챔버(21a)로 들어가는 오일의 압력이 5bay 정도라고 하면 오일이 오일쿨러의 쿨링핀(30)을 거치면서 유로저항에 의해 출구측 오일챔버(21b)로 나올때의 오일 압력은 4bay 정도에 불과하다.That is, when the pressure of the oil entering the oil chamber 21a at the inlet side of the oil cooler is about 5 bytes, the oil flows through the cooling pin 30 of the oil cooler to the oil chamber 21b at the outlet side The oil pressure is only about 4 bays.

그런데 오일이 오일쿨러를 거쳐 나올때의 적정압력이 4.3bay정도 되어야 만이 엔진의 각 윤활부위에 적당량의 오일을 공급하게 되는 것이고, 압력이 4bay이면 윤활부위에 적정한 오일을 공급치 못하게 된다.However, when the oil comes out through the oil cooler, the appropriate pressure should be about 4.3 bps to supply the proper amount of oil to each lubrication part of the engine. If the pressure is 4 bb, the lubrication part can not supply the proper oil.

따라서 오일 압력을 보상하기 위하여 오일을 공급해주는 오일펌프의 용량을 증대시키거나 오일펌프 릴리프밸브 스프링의 장력을 증대켜 강제적으로 오일압력을 증대시키는 방법이 있으나 이는 펌핑손실에 의한 연비저하 문제를 일으키게 된다.Accordingly, there is a method of increasing the capacity of the oil pump that supplies the oil to compensate the oil pressure, or increasing the tension of the oil pump relief valve spring to forcibly increase the oil pressure, but this causes a problem of fuel efficiency deterioration due to the pumping loss .

특히, 오일 압력을 높이기 위해 오일펌프용량을 증대시켜서 오일의 압력이 높아질 경우에는 압력에 의해 오일쿨러 내부의 쿨링핀(30)이나 튜브플레이트(20)가 견디지 못하고 크랙이 발생되어 오일과 냉각수가 혼합되는 경우가 발생되는 것이며, 혼합된 상태로 엔진의 각 부위로 공급되면 엔진이 제 성능을 발휘할 수 없는 문제점이 있는 것이다.In particular, when the oil pressure is increased by increasing the oil pump capacity to increase the oil pressure, the cooling pin 30 or the tube plate 20 inside the oil cooler can not withstand the pressure and cracks are generated, If the engine is supplied to various parts of the engine in a mixed state, the engine can not exhibit its performance.

이에 본 발명은 이와같은 종래의 문제점을 해결하기 위한 것으로 본 발명의 목적은 오일펌프의 용량을 증대시키지 않고서도 오일의 압력을 증대시켜 엔진의 각 부위에 적정의 오일이 공급되도록 하므로서 쿨링핀과 튜브플레이트에 크랙이 발생되는 것을 효과적으로 방지할 수 있도록 한 자동차용 오일쿨러를 제공하는데 있다.SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide an oil pump which increases the pressure of oil without increasing the capacity of the oil pump, And an object of the present invention is to provide an automotive oil cooler that can effectively prevent cracks from being generated in a plate.

본 발명의 목적을 달성하기 위해 본 발명은 쿨링핀이 오일용과 냉각수용으로 구분되어 구비된 다수의 튜브플레이트가 쿨러로워플레이트와 쿨러어퍼플레이트 사이에 적층되어 설치되고, 사방의 입ㆍ출구측 오일챔버와 입ㆍ출구측 냉각수챔버가 서로 격리되어 형성되는 자동차용 오일쿨러에 있어서, 입ㆍ출구측 오일챔버와 각각 통하는 바이패스홀과 바이패스출구가 구비된 바이패스플레이트를 맨위의 튜브플레이트와 쿨러어퍼플레이트 사이에 설치하고, 쿨러어퍼플레이트와 바이패스플레이트 사이에는 바이패스홀과 바이패스출구를 연결하는 바이패스통로를 구비한 것을 특징으로 한다.In order to achieve the object of the present invention, the present invention is characterized in that a plurality of tube plates, each having a cooling fin divided into an oil chamber and a cooling chamber, are stacked between a cooler plate and a cooler upper plate, And the inlet and outlet cooling water chambers are formed so as to be separated from each other, wherein the bypass plate having a bypass hole and a bypass outlet communicating with the inlet and outlet oil chambers, respectively, And a bypass passage connecting the bypass hole and the bypass outlet between the cooler upper plate and the bypass plate.

이와같은 본 발명은 오일쿨러로 들어간 오일의 일부가 쿨링핀을 거치면서 압력이 감소하더라도 곧바로 바이패스홀로 통과한 정상의 압력을 가진 오일과 합쳐지면서 정상압력이 되어 엔진의 각 부위에 적정오일이 공급되는 것이므로 압력강화를 위해 오일펌프의 용량을 증대시킬 필요가 없어 쿨링핀이나 튜브플레이트에 발생되는 크랙현상을 방지할 수 있는 효과가 있다.Even if a part of the oil entering the oil cooler passes through the cooling pin, even if the pressure decreases, the oil is immediately mixed with the oil having the normal pressure passed through the bypass hole, and the normal pressure is applied. Therefore, it is not necessary to increase the capacity of the oil pump in order to strengthen the pressure, and it is possible to prevent a cracking phenomenon occurring in the cooling pin or the tube plate.

이하 본 발명의 특징을 효과적으로 달성할 수 있는 바람직한 실시예로서 그 기술구성 및 작용효과를 첨부된 도면에 의해 상세히 설명하면 다음과 같다. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3은 본 발명에 따른 오일쿨러를 예시한 분리사시도이고, 도 4 는 본 발명에 따른 오일쿨러의 사시도이며, 도 5 는 본 발명에 따른 오일쿨러의 단면도이다.FIG. 3 is an exploded perspective view illustrating an oil cooler according to the present invention, FIG. 4 is a perspective view of an oil cooler according to the present invention, and FIG. 5 is a sectional view of an oil cooler according to the present invention.

이러한 본 발명은 쿨링핀(300)이 오일용과 냉각수용으로 구분되어 구비된 다수의 튜브플레이트(200)가 쿨러로워플레이트(100)와 쿨러어퍼플레이트(500) 사이에 적층되어 설치되고, 사방의 입ㆍ출구측 오일챔버(210a)(210b)와 입ㆍ출구측 냉각수챔버(220a)(220b)가 서로 격리되어 형성되는 자동차용 오일쿨러에 있어서, 입ㆍ출구측 오일챔버(210a)(210b)와 각각 통하는 바이패스홀(410)과 바이패스출구(420)가 구비된 바이패스플레이트(400)를 맨위의 튜브플레이트(200)와 쿨러어퍼플레이트(500) 사이에 설치한다.The present invention is characterized in that a plurality of tube plates 200 each having a cooling fin 300 separated from an oil and a coolant are stacked between a cooler plate 100 and a cooler upper plate 500, In the automotive oil cooler in which the outlet-side oil chambers 210a and 210b and the inlet-outlet-side cooling water chambers 220a and 220b are isolated from each other, the inlet and outlet oil chambers 210a and 210b, A bypass plate 400 having a bypass hole 410 and a bypass outlet 420 is installed between the upper tube plate 200 and the cooler upper plate 500.

그리고 쿨러어퍼플레이트(500)와 바이패스플레이트(400) 사이에는 바이패스홀(410)과 바이패스출구(420)를 연결하는 바이패스통로(510)를 구비한 것을 특징으로 한다.And a bypass passage 510 connecting the bypass hole 410 and the bypass outlet 420 between the cooler upper plate 500 and the bypass plate 400.

이와같은 본 발명은 엔진의 여러부분에서 발생되는 고온의 열에 의해 온도가 상승된 오일을 오일쿨러를 이용하여 냉각시켜 주도록 하는 것은 일반적인 기술구성이다.In the present invention as described above, it is a common technology to cool the oil whose temperature has been raised by the high temperature heat generated in various parts of the engine by using the oil cooler.

그러나 본 발명에서의 특징은 오일펌프의 용량을 증대시키지 않고서도 오일쿨러를 빠져나가는 오일의 압력을 강화시켜 오일을 필요로 하는 엔진의 여러부위에 적당한 양의 오일이 공급되도록 하므로서 오일쿨러 내부의 쿨링핀이나 튜브플레이트에 크랙이 발생되는 것을 방지할 수 있도록 한 것이다.However, it is a feature of the present invention that the pressure of the oil exiting the oil cooler is increased without increasing the capacity of the oil pump, so that an appropriate amount of oil is supplied to various parts of the engine requiring oil, So that cracks can be prevented from being generated in the pin or the tube plate.

즉, 본 발명은 별도의 바이패스플레이트(400)를 구비하여 쿨링핀(300)이 구비된 튜브플레이트(200)와 쿨러어퍼플레이트(500)사이에 설치되게 하고, 바이패스플레이트(400)에는 하측의 튜브플레이트(200)에 형성된 입구측 오일챔버(201a)와 일직선상 위치에 바이패스홀(410)을 형성하였다.That is, according to the present invention, the bypass plate 400 is installed between the tube plate 200 having the cooling fin 300 and the cooler upper plate 500, A bypass hole 410 was formed at a position in alignment with the inlet-side oil chamber 201a formed in the tube plate 200 of FIG.

또한 바이패스플레이트(400)에는 바이패스출구(420)를 형성한후 바이패스 홀(410)과 바이패스출구(420)를 바이패스통로(510)로 연결하였다.A bypass outlet 420 is formed in the bypass plate 400 and then the bypass hole 410 and the bypass outlet 420 are connected to the bypass passage 510.

따라서 오일이 오일쿨러의 입구측 오일챔버(210a)를 통해 오일쿨러 내로 유입되면 일부는 쿨링핀(300)을 통과하면서 입구측 냉각수챔버(220a)를 통해 들어온후 출구측 냉각수챔버(220b)로 나가는 냉각수에 의해 냉각된후 출구측 오일챔버(210b)로 나가게 되고, 일부는 곧바로 바이패스홀(410)을 빠져나가 바이패스통로(519)를 통해 바이패스출구(420)를 거친후 쿨링핀(300)을 통과한 오일과 합류하게 된다.Accordingly, when the oil flows into the oil cooler through the inlet-side oil chamber 210a of the oil cooler, a part of the oil passes through the cooling fin 300 and enters the inlet-side cooling water chamber 220a, The cooling water is cooled by the cooling water and then exits to the outlet side oil chamber 210b and a part of the cooling water passes directly through the bypass hole 410 and passes through the bypass outlet 420 through the bypass passage 519, To the oil that has passed through.

즉, 쿨링핀(300)을 통과하는 오일이 유로저항에 의해 압력이 낮아지면서 출구측 오일챔버(210a)로 나가는 것이나 곧바로 바이패스홀(410)을 통해 정상치의 압력을 가진 오일과 합쳐지면서 정상의 압력을 유지할 수 있으므로 엔진의 각 부위에 적정량의 오일을 공급할 수 있는 것이다. That is, the oil passing through the cooling fin 300 is lowered in pressure by the passage resistance, and is discharged to the oil chamber 210a at the outlet side, or immediately combined with the oil having the normal pressure through the bypass hole 410, The pressure can be maintained, so that an appropriate amount of oil can be supplied to each part of the engine.

여기서 바이패스플레이트(400)에 형성되는 바이패스홀(410)은 입구측 오일챔버(210a)를 통해 유입된 오일이 바이패스홀(410)보다는 튜브플레이트(200)의 쿨링핀(300)으로 충분히 유입되어 열교환을 이룰 수 있도록 입구측 오일챔버(210a)의 구경 지름보다 작은 소형으로 형성하였다.Here, the bypass hole 410 formed in the bypass plate 400 is formed so that the oil introduced through the inlet-side oil chamber 210a sufficiently flows into the cooling pin 300 of the tube plate 200 rather than the bypass hole 410 And is smaller than the diameter of the inlet-side oil chamber 210a so as to allow heat exchange with the inlet-side oil chamber 210a.

즉, 바이패스플레이트(400)에 바이패스홀(410)을 형성하였다 하더라도 구경이 작기 때문에 입구측 오일챔버(210a)를 통해 들어온 오일이 바이패스홀(410)로 바로 빠져나가는 양은 적고, 쿨링핀(300)을 거치는 양이 많아 충분히 냉각수와 열교환을 이룰수 있는 것이므로 일부 오일이 쿨링핀(300)을 거치지 않고 바이패스홀(410)로 곧바로 빠져나가더라도 오일을 냉각시키는데에는 아무런 문제가 없다.That is, even if the bypass hole 410 is formed in the bypass plate 400, since the diameter of the bypass hole 410 is small, the amount of oil that has flowed through the inlet side oil chamber 210a through the bypass hole 410 is small, There is no problem in cooling the oil even if some oil immediately escapes through the bypass hole 410 without passing through the cooling fin 300 because the amount of the oil passing through the cooling hole 300 is large.

그리고 바이패스홀(410)과 바이패스출구(420)를 연결하는 바이패스통로(510)는 별도로 설치하지 않고, 쿨러어퍼플레이트(500) 자체를 상측으로 포밍하여 형성하는 것이 바람직하다.It is preferable that the bypass passage 510 connecting the bypass hole 410 and the bypass outlet 420 is formed separately and is formed by upwardly forming the cooler upper plate 500 itself.
