Description
본 발명은 오일필터의 냉각장치에 관한 것으로서, 특히 오일필터를 통과하는 오일을 효과적으로 냉각시켜 오일의 점도가 적절한 상태를 유지되도록 하고, 냉각수에 포함되어 있는 이물질을 걸러주므로서 냉각수 이물질에 의한 엔진불량을 예방하며, 오일필터에 냉각장치를 일체로 형성하므로서 제품의 부품감소는 물론 별도의 오일쿨러를 구비하지 않아도 되도록 한 오일필터의 냉각장치에 관한 것이다.The present invention relates to a cooling device of an oil filter, in particular, to effectively cool the oil passing through the oil filter to maintain the viscosity of the oil to maintain an appropriate state, while filtering the foreign matter contained in the coolant, the engine failure due to the foreign matter of the coolant The present invention relates to a cooling device for an oil filter that prevents the need for a separate oil cooler as well as reducing parts of the product by forming a cooling device integrally with the oil filter.
일반적으로 고온과 고압속에서 고속으로 왕복운동하는 피스톤과 이에따른 여러 장치들이 서로 치합 및 마찰되는 엔진이나 많은 기어들이 서로 마찰되면서 고속으로 회전하는 변속기와 같은 경우, 고속으로 왕복운동하는 피스톤과 서로 치합되는 기어들과 이들을 회전시키는 축들의 결합 및 지지부위의 마찰과 열의 상승을 방지할 수 있도록 지속적인 오일의 공급이 필수적으로 요구되므로 통상, 엔진과 변속기의 하부에서 오일을 수용한 오일탱크를 두어 오일을 각 부위로 공급하게 되고, 이때 오일내의 불순물을 제거하기 위해 오일필터를 통과시키게 된다.In general, in the case of a piston that reciprocates at high speed at high temperature and high pressure, and an engine in which several devices engage and friction with each other, or a gearbox that rotates at high speed while many gears rub together, the piston reciprocates with a high speed reciprocating piston. It is usually necessary to supply the oil tank containing oil in the lower part of the engine and the transmission because it is necessary to continuously supply the oil to prevent the friction between the gears and the rotating shafts and the support and the friction of the heat. Each part is supplied to each part, and the oil filter is passed through to remove impurities in the oil.
이러한 오일필터는 도 3 에 도시된 바와같이 하단 플랜지(1)의 상측으로 그 내부에 오일순환경로를 가지면서 오일속에 포함되어있는 이물질을 걸러주기 위한 엘리먼트(3)가 오일순환경로상에 설치되어 있는 구조이다.Such an oil filter is provided with an element 3 for filtering foreign substances contained in the oil while having an oil pure environment therein above the lower flange 1, as shown in FIG. It is a structure.
그러나, 오일필터를 매개로 엔진이나 변속기로 유입된 오일이 다시 오일탱크로 복귀될때는 비교적 고온 상태로 되지만 이와같은 오일의 냉각수단이 오일필터에 구비되어 있지 않았기 때문에 온도에 의한 오일의 점성과 같은 물리적 특성 변화가 심해져 오일교환시기가 빨라짐은 물론 오일의 온도가 상승하면서 오일의 점도가 하락하게되어 각 마찰부품을 효과적으로 윤활하지 못하게되는 문제점이 발생하고 있었다.However, when the oil introduced into the engine or transmission is returned to the oil tank through the oil filter, the oil temperature is relatively high. However, since the oil cooling means is not provided in the oil filter, Due to the severe change in physical properties, the oil exchange time is not only faster, but also the viscosity of the oil decreases as the temperature of the oil rises, which causes a problem in that the friction parts cannot be lubricated effectively.
따라서, 상기 문제점을 해결하기 위한 본 발명은 오일이 유출입되는 몸체부의 외각으로 냉각수의 입출력을 위한 통로를 형성하고, 상기 통로와 연통되면서 필터하우징의 외각을 감싸도록 냉각수순환통로를 형성하되, 냉각수순환통로의 도중에 필터를 설치하므로서, 오일필터를 통과하는 오일을 효과적으로 냉각시켜 오일의 점도가 적절한 상태를 유지되도록 하고, 냉각수에 포함되어 있는 이물질을 걸러주므로서 냉각수 이물질에 의한 엔진불량을 예방하며, 오일필터에 냉각장치를 일체로 형성하므로서 제품의 부품감소는 물론 별도의 오일쿨러를 구비하지 않아도 되도록 한 오일필터의 냉각장치를 제공함을 목적으로 한다.Therefore, the present invention for solving the above problems is to form a passage for input and output of the cooling water to the outer shell of the body portion in which the oil flows in and out, and in communication with the passage to form a cooling water circulation passage to surround the outer shell of the filter housing, the cooling water circulation By installing the filter in the middle of the passage, the oil passing through the oil filter is effectively cooled to maintain the proper viscosity of the oil, and by filtering the foreign matter contained in the coolant to prevent engine failure caused by the foreign matter of the coolant. It is an object of the present invention to provide a cooling device for an oil filter, in which a cooling device is integrally formed on the filter so that the parts of the product are not only reduced, but also a separate oil cooler is not required.

이하 첨부된 도면 도 1 과 도 2 를 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 1 and 2.
도면부호 10 은 엔진에 장착되는 몸체부를 나타내며, 이 몸체부(10)에는 오일펌프에 의해 펌핑된 오일의 유입을 위한 오일유입통로(11)와 엘리먼트(17)를 통과한 오일의 배출을 위한 오일배출통로(12)가 몸체부(10)의 중앙부위에 형성되어 있다.Reference numeral 10 denotes a body portion mounted to the engine, the body portion 10 has oil for the discharge of the oil passing through the oil inflow passage 11 and the element 17 for the inflow of oil pumped by the oil pump Discharge passage 12 is formed in the central portion of the body portion (10).
또한 몸체부(10)의 외각으로는 서로 대향되는 위치에 냉각수의 유입을 위한 냉각수유입구(13)와 냉각수의 배출을 위한 냉각수배출구(14)가 각각 형성된다.In addition, a coolant inlet 13 for inlet of coolant and a coolant outlet 14 for discharging the coolant are respectively formed at positions facing each other at the outer sides of the body part 10.
상기 몸체부(10)의 상측으로는 그 내부로 필터하우징(16)이 일체로 형성되어 잇는 케이스(15)가 결합되는데, 상기 케이스(15)와 필터하우징(16)의 사이에는 냉각수의 순환을 위한 냉각수 순환통로(18)가 형성되며, 필터하우징(16) 내부에는 오일에 포함되어 있는 이물질을 걸러주기 위한 엘리먼트(17)가 형성된다.The upper side of the body portion 10 is coupled to the case 15, the filter housing 16 is formed integrally therein, the circulation of the coolant between the case 15 and the filter housing 16 The cooling water circulation passage 18 is formed, and an element 17 is formed inside the filter housing 16 to filter foreign substances contained in the oil.
몸체부(10)에 케이스(15)를 결합할때에는 필터하우징(16)이 오일유입통로(11)및 오일배출통로(12)와 연통되도록 하고, 케이스(15)와 필터하우징(16)의 사이에 형성되어있는 냉각수순환통로(18)가 상기 냉각수 유입구(13)및 냉각수 배출구(14)와 연통되도록 한다.When the case 15 is coupled to the body portion 10, the filter housing 16 communicates with the oil inflow passage 11 and the oil discharge passage 12, and between the case 15 and the filter housing 16. The cooling water circulation passage 18 formed in the main body is in communication with the cooling water inlet 13 and the cooling water outlet 14.
이에따라, 냉각수유입구(13)로 유입된 냉각수는 상기 냉각수순환통로(18)를 통해 순환하면서 필터하우징(16) 내부를 순환하는 오일을 냉각시킨 후 냉각수배출구(14)를 통해 배출되게 되며, 오일유입통로(11)로 유입된 오일은 필터하우징(16) 내부에 설치된 엘리먼트(17)에 의해 이물질이 제거된 후 다시 오일배출통로(12)로 배출되어 엔진의 각 마찰부품으로 공급되는것이며, 이과정에서 상기 냉각수순환통로(18)를 순환하는 냉각수에 의해 냉각되어 적절한 상태의 온도를 유지하게 된다.Accordingly, the coolant flowing into the coolant inlet 13 is circulated through the coolant circulation passage 18, cools the oil circulating in the filter housing 16, and is then discharged through the coolant outlet 14, and the oil inlet.

미설명된 도면부호 20은 몸체부(10)의 상면에 형성되는 밀폐링을 나타낸다.Unexplained reference numeral 20 denotes a sealing ring formed on the upper surface of the body portion 10.
상기 밀폐링(20)은 오일과 냉각수의 유출을 방지하기 위한 것으로서, 도 2 에 도시한 바와같이 밀폐링(20)을 이중구조의 환형상으로 형성시켜 상기 밀폐링(20)에 의해 오일부분과 냉각수부분이 서로 분할 격리되어 누출현상이 발생하지 않도록 하였으며, 냉각수의 입력측과 출력측을 구분하기 위한 분리부(21)를 밀폐링(20)의 내외각을 가로지르도록 형성하였다.The sealing ring 20 is to prevent the outflow of oil and cooling water, as shown in Figure 2 by forming the sealing ring 20 in a ring-shaped double structure of the oil portion by the sealing ring 20 and The cooling water parts were separated from each other to prevent leakage from occurring, and a separating part 21 for distinguishing the input and output sides of the cooling water was formed to cross the inside and outside angles of the sealing ring 20.
이와같이 구성된 본 발명의 동작을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.
엔진이 구동하면, 오일펌프의 동작에 의해 펌핑된 오일이 오일유입통로(11)를 통해 유입되어 필터하우징(16)의 내부를 통과하면서 엘리먼트(17)에 의해 이물질이 걸러져 오일배출통로(12)를 통해 배출되어 엔진의 각 마찰부품으로 공급되며, 도한 엔진 내부를 순환하는 냉각수의 일부가 상기 냉각수유입구(13)를 통해 유입되어 냉각수순환통로(18)를 순환하게 된다.When the engine is driven, the oil pumped by the operation of the oil pump flows through the oil inflow passage 11 and passes through the inside of the filter housing 16 to filter foreign matter by the element 17 and thus the oil discharge passage 12. It is discharged through and supplied to each friction part of the engine, and a portion of the coolant circulating in the engine is introduced through the coolant inlet 13 to circulate the coolant circulation passage 18.
이에따라, 필터하우징(16) 내부를 통과하는 오일이 상기 필터하우징(16)을 감싸도록 형성되는 냉각수순환통로(18)를 순환하는 냉각수에 의해 효과적으로 냉각되어 오일의 점도가 적절한 상태로 유지되는 것이다.Accordingly, the oil passing through the inside of the filter housing 16 is effectively cooled by the cooling water circulating through the cooling water circulation passage 18 formed to surround the filter housing 16 to maintain the viscosity of the oil in an appropriate state.
한편, 본 발명에 의하면, 상기 냉각수순환통로(18)의 도중에 구비되는 필터(19)에 의해 냉각수의 이물질이 걸러지게되므로 냉각수의 이물질에 의한 엔진의 불량을 미연에 방지할 수 있게되는 것이다.On the other hand, according to the present invention, since the foreign matter of the coolant is filtered by the filter 19 provided in the middle of the coolant circulation passage 18, it is possible to prevent the failure of the engine due to the foreign matter of the coolant in advance.
이상에서 설명한 바와같이 본 발명은 오일이 유출입되는 몸체부의 외각으로 냉각수의 입출력을 위한 통로를 형성하고, 상기 통로와 연통되면서 필터하우징의 외각을 감싸도록 냉각수순환통로를 형성하되, 냉각수순환통로의 도중에 필터를 설치하므로서, 오일필터를 통과하는 오일을 효과적으로 냉각시켜 오일의 점도가 적절한 상태를 유지되도록 하고, 냉각수에 포함되어 있는 이물질을 걸러주므로서 냉각수 이물질에 의한 엔진불량을 예방하며, 오일필터에 냉각장치를 일체로 형성하므로서 제품의 부품감소는 물론 별도의 오일쿨러를 구비하지 않아도 되도록 한 오일필터의 냉각장치를 제공하는 효과를 기대할 수 있다.As described above, the present invention forms a passage for input and output of the cooling water to the outer shell of the body portion through which oil flows in and out, and forms a cooling water circulation passage to cover the outer shell of the filter housing while being in communication with the passage, in the middle of the cooling water circulation passage. By installing the filter, the oil passing through the oil filter is effectively cooled to maintain the proper viscosity of the oil, and by filtering the foreign matter contained in the coolant to prevent engine defects caused by the foreign matter in the coolant and cooling the oil filter. By forming the device integrally, it is possible to expect the effect of providing a cooling device of the oil filter so as not to reduce the parts of the product as well as to provide a separate oil cooler.
