본 고안은 자동차용 실린더 블럭에 관한것으로서, 특히 실린더 블럭의 물재킷 형상을 변형하여 물재킷과 실린더와의 접촉면적을 증대시키므로써, 실린더 블럭의 전체적인 냉각효율을 높일 수 있는 자동차용 실린더 블럭에 관한 것이다.The present invention relates to a cylinder block for an automobile, and more particularly, to a cylinder block for an automobile that can improve the overall cooling efficiency of the cylinder block by increasing the contact area between the water jacket and the cylinder by modifying the shape of the water jacket of the cylinder block. will be.

일반적으로, 자동차 엔진의 연소기간중에 실린더 내에서 연소되는 가스의 온도는 약 2000~2500℃에 이르며, 이 열은 실린더 블럭, 실린더 헤드, 피스톤, 밸브 및 기타의 부품에 전도된다. 이러한 열에 의해 엔진이 과열되면 각 부품에 변형이 일어나고 또 윤활이 불충분하게되어 심할때에는 엔진이 손상되고, 또한 연소상태도 불량하게 되어 노킹이나 조기 점화를 일으켜 엔진의 출력이 저하된다.In general, the temperature of gas burned in a cylinder during the combustion period of an automotive engine is about 2000-2500 ° C., and this heat is conducted to cylinder blocks, cylinder heads, pistons, valves and other components. When the engine is overheated by such heat, deformation of each part occurs and lubrication is insufficient, and when the engine is severely damaged, the engine is damaged, and the combustion state is also poor, causing knocking or premature ignition, thereby lowering the engine output.

여기서, 첨부도면 제1도를 참고하여 기존의 실린더 블럭을 살펴보면, 상기 실린더 블럭(4)의 양측벽 즉, 실린더(3)의 주위에는 과열된 실린더 블럭(4)을 냉각시키기 위한 냉각수 통로인 물재킷(1)이 형성되어 있고, 실린더(3)의 내벽에는 라이너(2)가 삽입 장착되어 있다.Here, referring to FIG. 1 of the accompanying drawings, a conventional cylinder block is described. Water on both sides of the cylinder block 4, that is, around the cylinder 3, is a coolant passage for cooling the superheated cylinder block 4. A jacket 1 is formed, and a liner 2 is inserted into the inner wall of the cylinder 3.

이러한 상기 실린더 블럭(4)은 엔진이 작동할 때, 상당히 고온의 열을 받아 과열되게 되는데, 이때 상기 실린더 블럭(4)의 상부와 하부의 과열정도는 서로 큰 차이를 갖게 된다. 즉, 피스톤(6)이 상사점 가까이 위치하였을때 엔진의 폭발행정이 이루어지고, 이 폭발행성시 고온의 열이 발생하여 실린더 블럭(4)을 비롯한 각 부품들을 가열시키게 되므로 이때의 실린더 블럭(4)의 상부에 위치하게 되어 실린더 블럭(4)의 상부가 실린더 블럭(4)의 하부보다 더욱 많이 가열됨을 알 수 있다.The cylinder block 4 is overheated by the operation of the engine when the engine is operating at a very high temperature. At this time, the degree of overheating of the upper and lower portions of the cylinder block 4 is greatly different from each other. That is, when the piston (6) is located near the top dead center, the explosion stroke of the engine is made, and the high temperature heat is generated during this explosion planet to heat each part including the cylinder block (4), so that the cylinder block (4) It can be seen that the upper part of the cylinder block (4) is heated more than the lower part of the cylinder block (4) by being located at the top.

그러나, 실린더 블럭(4)을 냉각시키는 물재킷(1)의 단면적은 상부와 하부가 동일하게 형성되어 있어서, 이로 인하여 실린더 블럭(4)의 상부는 하부에 비해 상대적으로 효과적인 냉각이 이루어지지 못하는 단점이 있었다.However, the cross-sectional area of the water jacket 1 for cooling the cylinder block 4 is formed in the same upper and lower portions, and thus the upper portion of the cylinder block 4 is not relatively effective cooling compared to the lower portion. There was this.

본 고안은 이와같은 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은 실린더 블럭에 형성되어 있는 물재킷의 상부구조를 계단식으로 확대 개선하여 물재킷 상부의 단면적 및 물재킷과 실린더 블럭의 표면적을 증가시키므로써, 실린더 블럭의 냉각효율을 증대시킬 수 있는 자동차용 실린더 블럭을 제공함에 그 목적이 있다.The present invention was devised to solve such a problem, and an object of the present invention is to expand and improve the upper structure of the water jacket formed on the cylinder block stepwise to improve the cross-sectional area of the water jacket and the surface area of the water jacket and the cylinder block. By increasing, the object is to provide a cylinder block for automobiles that can increase the cooling efficiency of the cylinder block.

이하, 첨부도면을 참고하여 본 고안을 상세히 살펴보면 다음과 같다.Hereinafter, the present invention with reference to the accompanying drawings in detail as follows.

본 고안은 양측의 물재킷(1)을 갖는 실린더 블럭(4)에 있어서, 상기 물재킷(1)의 실린더측 전열면(5)은 윗쪽의 일정구간을 계단식 전열면(5)으로 이루어져 있는 것을 특징으로 한다.In the present invention, in the cylinder block (4) having the water jacket (1) on both sides, the cylinder-side heat transfer surface (5) of the water jacket (1) consists of a stepped heat transfer surface (5) in a certain section of the upper It features.

특히, 상기 계단식 전열면(5)은 윗쪽으로 갈수록 바깥쪽(예컨대, 실린더블럭 전체를 기준하여 볼때 안쪽)으로 확장되는 단차면으로 이루어져 있어서, 물재킷(1)의 상부가 하부에 비해 큰 체적을 갖게 된다.In particular, the stepped heat transfer surface (5) consists of a stepped surface that extends outward (for example, the inside when viewed relative to the entire cylinder block) toward the top, so that the upper portion of the water jacket (1) has a larger volume than the lower portion. Will have

이와같은 본 고안의 구성과 작용효과를 첨부도면 제2도를 참고하여 더욱 상세히 설명하면, 실린더 블럭(4)의 양측에 각각 내장되어 있는 물재킷(1)은 실린더(3)와 접하는 쪽의 전열면(5)이 경사면(5A)과 수직면(5B)의 반복구조로 이루어진 계단식 전열면(5)으로 이루어져 있고, 이러한 전열면(5)은 전체 전열면(5) 중에서 상부의 일정부분만 차지하게 된다.Referring to the configuration and operation effects of the present invention as described in more detail with reference to Figure 2, the water jacket (1), each of which is built on both sides of the cylinder block (4) is the front of the side in contact with the cylinder (3) The heat surface 5 consists of a stepped heat transfer surface 5 consisting of a repeating structure of the inclined surface 5A and the vertical surface 5B, and the heat transfer surface 5 occupies only a portion of the upper portion of the entire heat transfer surface 5. do.

즉, 실린더(3)쪽에 위치한 전열면(5)의 하단부에서부터 그 윗쪽으로의 일정위치에서 실린더(3)쪽을 향해 상향 경사면(5A)이 일정길이 형성된 후 이때의 상향경사면(5A)이 끝나는 지점에서 계속해서 수직면(5B)이 일정길이 형성되고 있고, 재차 상향 경사면(5A)이 일정길이 형성된후 수직면(5B)이 일정길이 형성되어 있으며 이와같은 반복구조를 통해서 최종적으로 수직면(5B)이 물재킷(1)의 상단 끝단면과 일치하게 되어 있다.That is, the point where the upward inclined surface 5A ends at this time after the upward inclined surface 5A is formed at a predetermined length from the lower end of the heat transfer surface 5 located on the cylinder 3 side toward the cylinder 3 toward the cylinder 3. The vertical surface 5B continues to be formed at a constant length, the upwardly inclined surface 5A is formed at a constant length, and then the vertical surface 5B is formed at a constant length, and the vertical surface 5B is finally formed through the repeating structure. It coincides with the upper end surface of (1).

즉, 상기 전열면(5)의 상부면 예컨대, 계단식 전열면(5)은 전체적으로 볼때 실린더(3)쪽으로 상향 경사진 구조로 이루어져 있다. 이때, 최상부에 위치되는 수직면(5B)은 실린더(3)에 가장 가까이 위치하게 되고, 또한 이 수직면(5B)의 위치는 엔진의 폭발행정시 실린더(3)의 피스톤(6)이 상사점에서 도달되어 있는 위치와 일치하게 된다. 따라서, 물재킷(1)의 일측전열면(5)은 하부보다 상부가 넓은 표면적으로 형성되어 있고, 또 물재킷(1)의 상부가 하부보다 넓은 단면적을 갖게되며, 동시에 이 물재킷(1)의 상측 전열면(5)은 가장 많이 가열되어 있는 실린더(3)의 상부와 가장 가까운 위치에 형성되어 있으므로, 상기 실린더 블럭(4) 상부를 보다 효율적으로 냉각시킬 수 있게된다.That is, the upper surface of the heat transfer surface 5, for example, the stepped heat transfer surface 5 is configured as a structure inclined upward toward the cylinder 3 as a whole. At this time, the vertical surface 5B positioned at the uppermost position is located closest to the cylinder 3, and the position of the vertical surface 5B reaches the piston 6 of the cylinder 3 at the top dead center during the engine explosion stroke. Will match the intended position. Therefore, the one side heat transfer surface 5 of the water jacket 1 is formed with a wider surface area than the lower part, and the upper part of the water jacket 1 has a larger cross-sectional area than the lower part, and at the same time the water jacket 1 Since the upper heat transfer surface 5 is formed at the position closest to the upper portion of the cylinder 3 which is most heated, the upper portion of the cylinder block 4 can be cooled more efficiently.

또한, 상기 물재킷(1)의 계단식 전열면(5)에 형성되어 있는 경사면(5A)은 물재킷(1)의 내부에서 유동되는 냉각수의 저항을 줄임과 동시에 이 냉각수에 와류를 형성시켜서 물재킷(1)내의 냉각수가 골고루 유동될 수 있게 해준다.Further, the inclined surface 5A formed on the stepped heat transfer surface 5 of the water jacket 1 reduces the resistance of the cooling water flowing in the water jacket 1 and simultaneously forms a vortex in the cooling water to form a water jacket. It allows the coolant in (1) to flow evenly.

이상에서와 같이 본 고안은 실린더 블럭이 갖고 있는 물재킷의 일측전열면을 계단식 전열면으로 형성시켜서 이 물재킷 상부의 단면적과 표면적을 증대시켜 주므로써, 실린더 블럭의 상부와 하부를 균일하게 냉각시킬 수가 있으며 실린더 블럭의 전체적인 냉각효율을 높일 수 있는 장점이 있다.As described above, the present invention forms the one-side heat transfer surface of the water jacket of the cylinder block as a stepped heat transfer surface to increase the cross-sectional area and the surface area of the upper water jacket, thereby uniformly cooling the top and bottom of the cylinder block. And it has the advantage of increasing the overall cooling efficiency of the cylinder block.
