Description

수냉식 적층형 오일쿨러{Laminated oil cooler of water-cooling type}Laminated oil cooler of water-cooling type

본 고안은 수냉식 적층형 오일쿨러에 관한 것으로서, 오일쿨러의 누설 가능 부위를 줄이고 조립성을 높이고 성능을 향상한 수냉식 적층형 오일쿨러에 관한 것이다.The present invention relates to a water-cooled laminated oil cooler, and to a water-cooled laminated oil cooler which has a possibility of reducing leakage of the oil cooler, improved assembly performance, and improved performance.

자동변속기에 사용되는 오일은 자동변속기가 변속될 때 윤활작용을 하여 마찰력을 최대한 줄여줌과 동시에 자동변속기에서 발생되는 마찰열을 흡수하여 자동변속기가 과열되는 것을 방지한다. 상기 마찰열을 흡수하여 소정온도 이상으로 가열된 오일은 그 상태에서는 더 이상의 마찰열 흡수가 잘 안되므로 오일에 흡수된 열을 방열시켜 냉각시켜 주어야만 하는데, 이러한 자동변속기의 오일 냉각은 보통 엔진의 냉각수를 식혀주는 라디에이터의 하단에 상기 자동변속기의 오일이 통과되는 수냉식 오일쿨러를 설치하여 오일이 오일쿨러를 통과할 때 그 주변의 냉각수와 열교환되면서 오일의 열이 방열되어 냉각되도록 하고 있다.The oil used in the automatic transmission lubricates the automatic transmission to reduce friction as much as possible and at the same time absorbs the frictional heat generated by the automatic transmission to prevent the automatic transmission from overheating. Since the oil heated by absorbing the frictional heat above a predetermined temperature cannot absorb any more frictional heat in this state, the oil absorbed by the oil must be cooled by dissipating the heat absorbed by the oil. At the bottom of the radiator, a water-cooled oil cooler through which the oil of the automatic transmission passes is installed so that the heat of the oil is radiated and cooled by heat-exchanging with the cooling water around when the oil passes through the oil cooler.

상기 수냉식 오일쿨러는 원통형 오일쿨러와 적층형 오일쿨러로 나누어진다. 상기 원통형 오일쿨러는 그 단면적이 라디에이터 헤드탱크의 크기에 따라 한정되고, 냉각성능의 증대를 필요로 할 경우 별도의 보조 오일쿨러를 장착해야 하는 문제가 있다. The water-cooled oil cooler is divided into a cylindrical oil cooler and a stacked oil cooler. The cylindrical oil cooler has a cross-sectional area is limited according to the size of the radiator head tank, there is a problem that a separate auxiliary oil cooler must be installed when the cooling performance needs to be increased.

종래 수냉식 적층형 오일쿨러는 도1에 도시한 바와 같이, 다수의 튜브플레이트(1)가 적층되어 그 내부에 오일이송공간이 형성되고, 적층된 튜브플레이트의 양측에 오일입구(2) 및 오일출구(3)가 각각 형성된 구조로 되어 있다. 이러한 수냉식 적층형 오일쿨러는 수냉식 원통형 오일쿨러에 비해 한정된 헤더탱크 단면적을 최대로 이용하고 고효율을 얻을 수 있다.In the conventional water-cooled stacked oil cooler, as shown in FIG. 1, a plurality of tube plates 1 are stacked to form an oil transfer space therein, and oil inlets 2 and oil outlets are formed on both sides of the stacked tube plates. 3) is formed respectively. Such a water-cooled stacked oil cooler can maximize the use of a limited header tank cross-sectional area and obtain high efficiency compared to a water-cooled cylindrical oil cooler.

그런데, 종래 수냉식 적층형 오일쿨러는 프레스 가공한 판을 적층하여 오일쿨러를 제조하므로, 적층되어 용착되는 부위가 많으므로 장기간 사용함에 따라 오일이 누설된 가능성이 높아지고, 종래 수냉식 원통형 오일쿨러는 성능이 낮다는 문제점이 있다.However, the conventional water-cooled laminated oil cooler manufactures an oil cooler by laminating press-formed plates, and thus, many parts are laminated and welded to increase the possibility of oil leakage during long-term use, and the conventional water-cooled cylindrical oil cooler has low performance. Has a problem.

따라서, 본 고안은 상기 문제점을 해결하기 위해 이루어진 것으로서, 본 고안의 목적은 오일쿨러의 누설 가능 부위를 줄이고 조립성이 양호하고 콤팩트하며 성능이 향상된 수냉식 적층형 오일쿨러를 제공하는 데 있다.Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a water-cooled laminated oil cooler with improved leakability and compactness and improved performance of the oil cooler.

상기 목적을 달성하기 위한 본 고안에 의한 수냉식 적층형 오일쿨러는, 두 개의 탱크 사이에는 압출성형된 다수의 압출튜브가 일정한 간격으로 상기 탱크에 연통하여 설치되고, 상기 인접하는 압출튜브 사이에는 열교환 효율을 향상하도록 핀이 삽입되며, 상기 압출튜브의 양단은 인접하는 압출튜브와 서로 마주보는 방향으로 절곡되어 상기 탱크에 각각 삽입되고, 상기 각 탱크에는 오일입구부재 및 오일출구부재가 결합되어 있는 것을 특징으로 한다.Water-cooled laminated oil cooler according to the present invention for achieving the above object, a plurality of extruded extruded tube between the two tanks are installed in communication with the tank at regular intervals, between the adjacent extruded tube to improve the heat exchange efficiency A pin is inserted to improve, and both ends of the extruded tube are bent in a direction facing each other with adjacent extruded tubes and inserted into the tank, respectively, wherein the oil inlet member and the oil outlet member are coupled to each tank. do.

상기 탱크와 압출튜브와 핀과 오일입구부재 및 오일출구부재는 가조립되어 브레이징됨에 의해 일체로 되어 있다. The tank, the extruded tube, the pin, the oil inlet member and the oil outlet member are integrally assembled by brazing.

도2는 본 고안에 의한 수냉식 적층형 오일쿨러를 나타내는 입면도이고, 도3은 도2의 오일쿨러의 일측부를 상세히 나타낸 사시도이다. 도시한 바와 같이, 본 고안에 의한 수냉식 적층형 오일쿨러(10)는 일측탱크(11)와 타측탱크(12) 사이에는 압출성형된 다수의 압출튜브(13)가 일정한 간격으로 상기 일측탱크(11) 및 타측탱크(12)에 연통하여 설치되고, 상기 인접하는 압출튜브(13, 13) 사이에는 열교환 효율을 향상하도록 핀(14)이 삽입되며, 상기 압출튜브(13)의 양단은 인접하는 압출튜브(13)와 서로 마주보는 방향으로 절곡된 절곡부(13a)를 이루고 이 절곡부(13a)가 상기 일측탱크(11) 및 타측탱크(12)의 도시하지 않은 튜브삽입구멍에 각각 삽입된다. 상기 일측탱크(11)의 측부에는 오일입구부재(15)가 결합되고, 상기 타측탱크(12)의 측부에는 오일출구부재(16)가 결합되어 있다.Figure 2 is an elevation view showing a water-cooled stacked oil cooler according to the present invention, Figure 3 is a perspective view showing one side of the oil cooler of Figure 2 in detail. As illustrated, the water-cooled stacked oil cooler 10 according to the present invention has a plurality of extruded extrusion tubes 13 extruded between one side tank 11 and the other side tank 12 at regular intervals. And it is installed in communication with the other side tank 12, between the adjacent extruded tube (13, 13) is inserted into the fin 14 to improve the heat exchange efficiency, both ends of the extruded tube 13 are adjacent extruded tube A bending portion 13a bent in a direction facing each other with 13 is formed, and the bending portion 13a is inserted into a tube insertion hole (not shown) of the one side tank 11 and the other side tank 12, respectively. An oil inlet member 15 is coupled to a side of the one side tank 11, and an oil outlet member 16 is coupled to a side of the other side tank 12.

상기 일측탱크(11)와 타측탱크(12)와 압출튜브(13)와 핀(14)과 오일입구부재(15) 및 오일출구부재(16)는 가조립되어 브레이징됨에 의해 일체로 되어 있다.The one side tank 11, the other side tank 12, the extrusion tube 13, the pin 14, the oil inlet member 15, and the oil outlet member 16 are integrally assembled and brazed.

상기 압출튜브(13)는 그 내부에 오일통로가 형성된 알루미늄재의 납작튜브로 되어 있고, 상기 핀(14)은 주름진 코루케이트 핀이나 이너핀 등 다양한 형상의 핀으로 되어 있다. 상기 핀(14)은 클래드 소재이면 어떠한 형상의 핀도 사용가능하다. 그리고, 오일쿨러가 라디에이터(도4에 도시)에 조립된 후 상기 오일입구부재(15) 및 오일출구부재(16)에는 파이프가 조립된다. 상기 압출튜브(13)의 양단은 2개씩 서로 마주보는 방향으로 절곡되어 상기 일측탱크(11) 및 타측탱크(12)에 각각 삽입되어 있으므로 2개의 서로 마주보는 압출튜브(13)(13)사이에 삽입되는 핀은 가조립시에 이탈가능성이 낮아지게 되어 조립성이 양호하며 오일쿨러를 콤팩트하게 제조할 수 있다.The extruded tube 13 is a flat tube made of an aluminum material having an oil passage therein, and the pin 14 is a pin having various shapes such as corrugated pins and inner pins. The pin 14 may be any shape fin as long as it is a clad material. Then, after the oil cooler is assembled to a radiator (shown in FIG. 4), pipes are assembled to the oil inlet member 15 and the oil outlet member 16. Both ends of the extruded tube 13 are bent in a direction facing each other, so that the two ends are inserted into the one side tank 11 and the other side tank 12, respectively, so that the two extruded tubes 13 and 13 face each other. Since the pin to be inserted becomes less likely to detach during assembly, the assembly is good and the oil cooler can be manufactured compactly.

그리고, 상기 압출튜브(13)는 길이를 자유롭게 선택하여 제조할 수 있는데, 라디에이터의 탱크 크기가 무한정 커지면 차량의 레이아웃에 영향을 받고 그만큼 가격도 올라가므로 압출튜브(13)의 양단을 절곡하여 그 크기를 제한하는 효과도 있다.In addition, the extruded tube 13 may be manufactured by freely selecting the length. When the tank size of the radiator is infinitely large, the size of the extruded tube 13 is bent by the layout of the vehicle. There is also the effect of limiting.

도4는 상기 오일쿨러가 라디에이터의 하측탱크(22)내에 설치된 상태를 나타낸다. 상기 라디에이터의 하측탱크(22) 양측에는 냉각수입출구부(23, 24)가 형성되어 있다. 4 shows a state where the oil cooler is installed in the lower tank 22 of the radiator. Cooling water inlet and outlet portions 23 and 24 are formed at both sides of the lower tank 22 of the radiator.

이와 같이 구성된 본 고안에 의한 수냉식 적층형 오일쿨러는, 압출성형된 압출튜브가 핀을 사이에 두고 적층되어 있으므로, 오일쿨러의 누설가능부위가 줄어 품질이 안정되고 오일쿨러의 유로와 튜브사이의 간격이 넓어지게 되어 성능이 향상되는 효과가 있다. 그리고, 본 고안의 오일쿨러는 전체를 알루미늄으로 하여 일체 브레이징이 가능하므로 콤팩트하게 제조할 수 있으며 제조하기가 용이하다.In the water-cooled laminated oil cooler according to the present invention configured as described above, since the extruded extruded tube is laminated with the pins interposed therebetween, the leakable portion of the oil cooler is reduced and the quality is stable, and the gap between the oil cooler flow path and the tube is reduced. The wider the performance is improved. In addition, since the oil cooler of the present invention can be integrally brazed using aluminum as a whole, it can be manufactured compactly and is easy to manufacture.
