Description

냉각성능이 개선된 내연기관의 실린더헤드Cylinder head of internal combustion engine with improved cooling performance

본 고안은 냉각성능이 개선된 내연기관의 실린더헤드에 관한 것으로서, 보다 상세하게는 실린더블록의 보어와 보어사이를 효율적으로 냉각시켜 주므로써 실린더블록의 온도차를 줄여 내구성을 향상시키고, 엔진의 성능도 향상시킬 수 있는 냉각성능이 개선된 내연기관의 실린더헤드에 관한 것이다.The present invention relates to a cylinder head of an internal combustion engine with improved cooling performance, and more particularly, by efficiently cooling the bore between the bore and the bore of the cylinder block to reduce the temperature difference of the cylinder block, thereby improving durability and improving engine performance. The present invention relates to a cylinder head of an internal combustion engine having improved cooling performance.

일반적으로 엔진의 작동중 엔진이 과열되지 않고 적당한 온도를 유지하여 엔진이 손상되지 않도록 하기 위하여 엔진을 냉각시켜야 한다. 그리하여 엔진의 냉각방법에는 자동차의 주행중 냉각팬에 의해 공기로 냉각시키는 공냉식과 냉각수를 사용하여 엔진 내부를 냉각시키는 수냉식이 있으며, 일반적으로는 수냉식이 사용되고 있다.In general, the engine must be cooled in order to prevent the engine from overheating while maintaining the proper temperature during engine operation to prevent damage to the engine. Thus, in the engine cooling method, there is an air cooling method for cooling the inside of the engine by using an air cooling type that cools with air by a cooling fan while the vehicle is running, and a water cooling type is generally used.

첨부된 도면 도 1은 종래의 실린더블록의 평면도를 도시한 것으로서, 실린더블록(10)에는 다수의 보어(12)가 형성되며, 상기 보어(12)에 피스톤(도시생략)이 삽입되어 상,하 왕복운동을 하게 된다. 또한 상기 실린더블록(10)의 일측에는 다수의 워터재킷(30)이 형성되어 고온의 실린더블록(10)을 라디에이터(도시생략)에서 냉각된 냉각수가 워터펌프(도시생략)에 의하여 실린더블록(10)의 워터재킷(30)으로 유입되어 이 냉각수가 상기 실린더블록(10)을 냉각시키게 된다.1 is a plan view of a conventional cylinder block, in which a plurality of bores 12 are formed in a cylinder block 10, and a piston (not shown) is inserted into the bore 12 to move up and down. It will reciprocate. In addition, a plurality of water jackets 30 are formed at one side of the cylinder block 10 so that the coolant cooled by the radiator (not shown) to the high temperature cylinder block 10 is not shown by the water pump (not shown). The coolant is introduced into the water jacket 30 to cool the cylinder block 10.

그러나 이와 같은 실린더블록의 냉각계통은 냉각수가 엔진의 실린더블록에서 실린더헤드로 순환하도록 되어 있는데, 엔진의 실린더블록은 보어와 보어사이의 온도가 가장 높다. 그런데 냉각수가 실린더블록을 순환할 때에는 보어와 보어사이를 통과하지 않게 되어 실린더블록의 냉각작용이 잘 이루어지지 않게 되어 엔진의 성능이 저하되는 문제점이 있었다.However, the cooling system of the cylinder block is such that the coolant is circulated from the cylinder block of the engine to the cylinder head, the cylinder block of the engine has the highest temperature between the bore and the bore. However, when the coolant circulates through the cylinder block, the coolant does not pass between the bore and the bore, so that the cooling action of the cylinder block is not performed well, thereby degrading the performance of the engine.

그리하여 실린더블록의 주조시에 주물의 내부에 코어를 삽입하여 실린더블록의 보어와 보어사이의 소정부 일측에 냉각수통로를 형성하는데, 이러한 냉각수통로를 가공할 시에 상기 코어를 지지하기가 대단히 까다롭고, 실린더블록의 보어와 보어 사이의 살두께가 얇아 주조시에 코어가 유동하게 되면 상기 보어와 보어사이의 살두께를 더욱 얇게 형성하여 취약하게 되므로 실린더블록의 보어와 보어사이의 살두께가 9mm이상일 경우에 한에서만 생산가능한 문제점이 있었다.Thus, during casting of the cylinder block, a core is inserted into the casting to form a cooling water passage on one side between the bore and the bore of the cylinder block, which is very difficult to support the core when machining the cooling water passage. When the core flows at the time of casting because the thickness of the flesh between the bore and the bore of the cylinder block is thin, the thickness of the bore and the bore becomes more vulnerable because the thickness of the bore and the bore of the cylinder block is 9 mm or more. Only in cases where there was a productable issue.

본 고안은 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 실린더블록의 보어와 보어사이의 고온의 열을 실린더헤드의 워터재킷측으로 신속하게 열전달이 이루어지게 함으로써 상기 실린더블록은 냉각수에 의해 전반적으로 냉각되고, 보어와 보어사이의 고온의 열은 상기 실린더헤드의 워터재킷측으로 신속하게 열전달되어 냉각되므로 상기 실린더블록의 온도차를 줄여 내구성을 향상시키고, 엔진의 성능도 향상시킬 수 있도록 한 냉각성능이 개선된 내연기관의 실린더헤드를 제공하는데 그 목적이 있다.The present invention is to solve the conventional problems as described above, the heat of the high temperature between the bore and the bore of the cylinder block by the heat transfer to the water jacket side of the cylinder head is quickly cooled by the coolant as a whole The high temperature heat between the bore and the bore is rapidly transferred to the water jacket side of the cylinder head to cool, thereby reducing the temperature difference of the cylinder block, thereby improving durability and improving the engine performance. The purpose is to provide a cylinder head of an internal combustion engine.

상술한 목적을 달성하기 위한 본 고안의 기술적 구성은 자동차 엔진의 실린더블록 상단에 안착되어 고정되는 실린더헤드에 있어서, 상기 실린더헤드에 구비된 보어와 보어사이에 열전도성이 좋은 금속편을 삽입하여 상기 실린더블록의 보어와 보어사이의 고온의 열을 상기 금속편의 일측 상단에 구비된 워터재킷측으로 신속하게 전도시켜 실린더블록의 냉각효율을 좋게 한 것을 특징으로 한다.The technical configuration of the present invention for achieving the above object is a cylinder head seated and fixed to the top of the cylinder block of the automobile engine, inserting the metal piece having a good thermal conductivity between the bore and the bore provided in the cylinder head to the cylinder It is characterized in that the high temperature heat between the bore of the block and the bore is quickly conducted to the water jacket side provided on one side upper end of the metal piece to improve the cooling efficiency of the cylinder block.
