Description
본 고안은 내연기관, 특히 자동차용 엔진의 실린더 블록 냉각수 강제유동장치에 관한 것으로, 보다 구체적으로는, 실린더 블록의 냉각수로에서 순환되는 냉각수를 강제유동시키므로써, 실린더 블록의 냉각효율을 높일 수 있는 실린더 블록의 냉각수 강제유동장치에 관한 것이다.The present invention relates to a forced forced flow of a cylinder block coolant of an internal combustion engine, in particular, an automobile engine. More specifically, the cooling efficiency of the cylinder block can be increased by forcibly flowing the coolant circulated in the coolant passage of the cylinder block. It relates to a coolant forced flow device of the cylinder block.
자동차용 엔진등과 같은 내연기관에는 과열을 방지하고 적당한 온도로 유지시켜 주기 위한 냉각장치(Cooling System)가 설치된다.Internal combustion engines, such as automotive engines, are equipped with a cooling system to prevent overheating and to maintain the proper temperature.
내연기관의 실린더 내부의 연소가스 온도는 2,000℃ 이상에 이르며, 이 열의 상당한 양이 실린더, 실린더 헤드, 피스톤, 밸드 등에 전도된다.The combustion gas temperature inside the cylinder of the internal combustion engine reaches 2,000 ° C. or more, and a significant amount of this heat is conducted to the cylinder, cylinder head, piston, ball, and the like.
이러한 구성품들의 온도가 과도하게 높아지면, 부품 재료의 강도가 저하되고, 고장이 생기거나 수명이 단축되고, 연소상태도 나빠져 노킹이나 혼합기가 조기점화되어 기관의 출력이 저하되는 현상이 일어난다. 또한, 냉각이 불완전한 상태에서는 실린더 벽의 유막이 끊기는 등의 윤활기능의 저하와 오일의 변징 등으로, 실린더 벽이 이상마모되거나 피스톤이 실린더 벽에 눌어 붙는 등, 고장원인이 된다.If the temperature of these components is excessively high, the strength of the part material is lowered, failure or life is shortened, the combustion state is worsened, and knocking or premature ignition of the engine results in a decrease in engine output. In addition, in the incomplete cooling state, failure of lubrication function such as breakage of the oil film on the cylinder wall, change of oil, etc. may cause abnormal wear of the cylinder wall or piston sticking to the cylinder wall.
그러나, 반대로 내연기관이 지나치게 냉각되면 연소에서 발생한 열량 가운데 냉각으로 손실되는 열량이 크기 때문에, 기관의 열효율이 낮아지고 연료 소비량이 증가하는 등의 문제가 발생하므로, 기관의 온도를 알맞게 유지시켜야 한다.On the contrary, if the internal combustion engine is excessively cooled, the amount of heat lost by cooling is large among the heat generated from combustion, so that the engine thermal efficiency is lowered and fuel consumption is increased. Therefore, the temperature of the engine must be properly maintained.
이렇게 기관을 적당한 온도로 냉각시켜주기 위하여 설치되는 것이 냉각장치이다.The cooling device is installed to cool the engine to a proper temperature.
본 고안은 냉각장치의 한 구성을 이루는 장치로, 내연기관의 실린더 벽체의 냉각수로에서 냉각수를 강제유동시키므로써 내연기관에 대한 냉각효율을 높이는 실린더 블록의 냉각수 강제유동장치이다.The present invention is a device forming one configuration of the cooling device, the forced flow of the cooling water in the cooling water passage of the cylinder wall of the internal combustion engine by the forced cooling device of the cylinder block to increase the cooling efficiency for the internal combustion engine.
종래에는 내연기관의 실린더 블록을 냉각시키는 방식으로, 실린더 블록 주위에 냉각수로를 형성하고, 이 부분에 워터 펌프에서 펌핑되는 냉각수를 순환시키는 방식이 많이 사용되어 왔다.Conventionally, a method of cooling a cylinder block of an internal combustion engine, a cooling water path is formed around the cylinder block, and a method of circulating the cooling water pumped by the water pump has been widely used.
그러나, 상술한 바와 같이 워터 펌프에만 의존하는 종래의 실린더 블록 냉각 방식은 냉각수의 유동이 활발하지 못하기 때문에 실린더 블록에 대한 냉각효율이 좋지 못하다. 따라서, 종래에는 실린더 블록에 대한 냉각이 불완전하게 이루어지므로 기관이 과열되는 사례가 발생하여, 이 열에 의한 내마모성 저하로 실린더 블록과 피스톤 링의 마찰면이 쉽게 마모되는 문제점이 있었다.However, as described above, the conventional cylinder block cooling method that relies only on the water pump has a poor cooling efficiency for the cylinder block because the flow of cooling water is not active. Therefore, in the related art, since the cooling of the cylinder block is incompletely performed, the engine is overheated, and the frictional surface of the cylinder block and the piston ring is easily worn due to the lowered wear resistance.
본 고안은 이와같은 종래의 문제점을 해소시키기 위하여 안출된 것으로, 실린더 블록의 냉각수를 강제로 유동시켜 실린더 블록에 대한 냉각효율을 높이고, 따라서 실린더가 과열되지 않게 하므로써, 실린더 블록 및 피스톤 링의 열에 의한 내마모성 저하를 막아 이들의 내구수명을 연장시킬 수 있는 실린더 블록의 냉각수 강제유동장치를 제공하는 것을 목적으로 한다.The present invention was devised to solve such a conventional problem, and by forcibly flowing the cooling water of the cylinder block to increase the cooling efficiency for the cylinder block, thereby preventing the cylinder from overheating, by the heat of the cylinder block and piston ring It is an object of the present invention to provide a coolant forced flow device of a cylinder block which can prevent abrasion resistance from deteriorating and extend their service life.

상기한 바와 같은 목적을 가지고 본 고안의 구성 및 작용을 첨부된 도면에 제시된 바람직한 일 실시예를 통하여 구체적으로 설명한다.The construction and operation of the present invention for the purpose as described above will be described in detail through one preferred embodiment shown in the accompanying drawings.
첨부된 도면의 도 1 은 본 고안의 실린더 블록 냉각수 강제유동장치의 단면도이고, 도 2 는 본 고안의 실린더 블록의 냉각수 강제유동장치의 냉각수 와류판 사시도이며, 도 3 은 본 고안에 따른 피스톤 사시도이다.Figure 1 of the accompanying drawings is a cross-sectional view of the cylinder block cooling water forced flow apparatus of the present invention, Figure 2 is a perspective view of the cooling water vortex plate of the cooling water forced flow apparatus of the cylinder block of the present invention, Figure 3 is a perspective view of the piston according to the present invention .
도 1 에 도시된 바와 같이, 본 고안의 실린더 블록의 냉각수 강제유동장치는 실린더 블록(1)의 냉각수로(1a)에 설치되는 냉각수 와류판(2)과, 상기 와류판(2)을 탄성지지하는 압축스프링(3)으로 구성되어 있다.As shown in Figure 1, the cooling water forced flow device of the cylinder block of the present invention is a cooling water vortex plate (2) which is installed in the cooling water passage (1a) of the cylinder block (1), and the vortex plate (2) to elastically support It consists of the compression spring (3).
상기 와류판(2)은 도 2 에 도시된 바와 같이, 다수의 와류공이 형성된 원환 띠 형상의 판으로, 실린더 블록(1)의 냉각수로(1a)에 내장되며, 그 내주부에는 4개의 고정핀(2a)이 설치된다.As shown in FIG. 2, the vortex plate 2 is a ring-shaped plate in which a plurality of vortex holes are formed, and is embedded in the cooling water passage 1a of the cylinder block 1, and four fixing pins are formed on the inner circumference thereof. (2a) is provided.
상기 고정핀(2a)은 실린더 블록(1)에 소정의 높이로 형성된 통공을 통하여 실린더 내경부측으로 돌출되며, 이 끝단은 승강되는 피스톤(4)의 외주부에 걸리게 된다.The fixing pin (2a) is projected toward the cylinder inner diameter side through the through-hole formed in the cylinder block 1 to a predetermined height, the end is caught by the outer peripheral portion of the piston (4) to be elevated.
도 3 에 도시된 바와 같이, 상기 고정핀(2a)들에 대응되는 피스톤(3) 상면의 외주에는 고정핀(2a)이 삽입될 수 있는 안내홈(4a)이 각각 형성된다. 따라서, 고정핀(2a)은 상기 피스톤(4)의 안내홈(4a)에 끼워져 그 승강을 안내받게 된다.As shown in FIG. 3, guide grooves 4a into which the fixing pins 2a can be inserted are formed on the outer circumference of the upper surface of the piston 3 corresponding to the fixing pins 2a, respectively. Therefore, the fixing pin 2a is fitted into the guide groove 4a of the piston 4 to guide the lifting.
그리고, 고정핀(2a)이 관통되는 실린더 블록(1)의 통공의 위쪽에는 압축스프링(3)이 설치되며, 이는 고정핀(2a)을 탄성지지하여 피스톤(4)에 의하여 상승된 고정핀(2a)을 아래쪽으로 복원시킨다.In addition, a compression spring 3 is installed above the through hole of the cylinder block 1 through which the fixing pin 2a penetrates, which is elastically supporting the fixing pin 2a so as to be lifted by the piston 4. Restore 2a) downward.
이상과 같은 구성으로, 엔진의 구동시, 피스톤(4)과 압축스프링(3)의 작용으로, 와류판(2)의 상하로 요동치면서 냉각수로(1a)에 냉각수를 강제로 유동시킨다. 따라서, 냉각수로(1a)내에서의 냉각수 유동이 활발해짐에 따라 냉각장치의 실린더 블록(1)에 대한 냉각효과가 높아지게 된다.With the above configuration, the cooling water is forced to flow into the cooling water passage 1a while swinging up and down the vortex plate 2 by the action of the piston 4 and the compression spring 3 when the engine is driven. Therefore, as the cooling water flow in the cooling water passage 1a becomes active, the cooling effect on the cylinder block 1 of the cooling apparatus is increased.
이렇게 실린더 블록(1)의 냉각효과가 증대됨에 따라 실린더 블록(1)의 실린더와 피스톤(4)의 피스톤 링의 열변성에 의한 내마모성 저하를 막아 마찰면의 마모를 현저히 줄일 수 있다.As the cooling effect of the cylinder block 1 is increased in this way, the wear resistance of the friction surface can be remarkably reduced by preventing the wear resistance caused by the thermal deformation of the cylinder of the cylinder block 1 and the piston ring of the piston 4.
이상에서 상세히 설명한 바와 같은 본 고안의 실린더 블록 냉각수 강제유동 장치를 실린더에 설치함으로써, 실린더 냉각수로의 냉각수 유동을 보다 활발하게 만들 수 있으며, 따라서 실린더 보다 효과적으로 냉각시킬 수 있다. 이렇게 실린더의 냉각효과가 증대됨에 따라 실린더 및 피스톤 링의 열에 의한 내마모성의 저하를 막을 수 있어서, 이들 부품들의 내구수명이 크게 연장되는 효과가 있다.By installing the cylinder block cooling water forced flow apparatus of the present invention as described above in detail in the cylinder, it is possible to make the cooling water flow to the cylinder cooling water more active, and thus to cool more effectively than the cylinder. As the cooling effect of the cylinder is increased in this way, deterioration of wear resistance due to heat of the cylinder and the piston ring can be prevented, so that the durability life of these parts is greatly extended.
본 고안은 실용신안등록청구의 범위에서 청구하는 요지를 벗어나지 않고 당해 고안이 속하는 분야에서 통상의 지식을 가진 자가 다양하게 변경하여 실시할 수 있으므로, 본 고안의 상술한 특정의 실시예에 한정되지 않는다.The present invention can be variously modified and implemented by those skilled in the art without departing from the scope of the claims for utility model registration, it is not limited to the specific embodiments described above of the present invention .
