본 고안은 냉각수의 흐름을 용이하게 하여 냉각성능을 향상시키게 되는 장치에 관한 것이다.The present invention relates to an apparatus for improving the cooling performance by facilitating the flow of cooling water.

엔진은 고속으로 운전되고 고온의 연소열의 영향을 받기 때문에 열팽창으로 인한 파손을 방지하기 위하여 냉각수를 순환시켜 적절한 온도로 냉각시키게 된다.Since the engine operates at high speed and is affected by high heat of combustion, the coolant is circulated and cooled to an appropriate temperature to prevent breakage due to thermal expansion.

이를 위해 제2도에 도시하는 것과 같이 실린더블록과 실린더헤드에는 워터재킷(20)을 형성하고 크랭크축에 연동하여 작동하는 워터펌프(21)에 의해 냉각수를 강제로 순환시키고 있다.To this end, as shown in FIG. 2, the water block 20 is formed in the cylinder block and the cylinder head, and the coolant is forcibly circulated by the water pump 21 which operates in conjunction with the crankshaft.

한편 최근에 엔진은 고속고출력화되는 추세이기 때문에 효율성이 높은 냉각시스템이 요구되고 있으나 워터펌프에만 의존하게 되므로써 워터재킷내의 유동성이 나쁠 경우 엔진과열을 일으켜 엔진을 손상시키게 되는 일이 벌어질 수 있다.On the other hand, in recent years, since the engine is becoming a high speed and high output power, an efficient cooling system is required, but since only the water pump depends on the fluidity in the water jacket, the engine may overheat and damage the engine.

이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 바는 냉각수의 흐름을 용이하게 하여 냉각성능을 향상시킨 엔진냉각성능 향상장치를 제공하는 데 있다.Accordingly, the present invention has been proposed in view of the above problems, and an object thereof is to provide an engine cooling performance improving apparatus which improves cooling performance by facilitating the flow of cooling water.

상기한 목적을 달성하기 위하여 본 고안은 실린더블록과 실린더헤드에 형성되는 워터재킷과 실린더블록의 워터재킷 입구부에 설치되어 냉각수를 강제 순환시기는 워터펌프에 있어서, 상기 실린더블록의 워터재킷에 마련되어 실린더헤드에 공급되는 냉각수의 유속을 증가시키도록 회전 구동되는 임펠러와, 상기 임펠러를 구동하기 위한 임펠러용 풀리와, 상기 워터펌프 풀리의 회전력을 상기 임펠러용 풀리에 전달하는 벨트와로 구성되는 것을 특징으로 한다.In order to achieve the above object, the present invention is provided in the water jacket formed in the cylinder block and the cylinder head and the water jacket inlet portion of the cylinder block is provided in the water jacket of the cylinder block in the water pump for forced circulation of the coolant An impeller that is rotationally driven to increase the flow rate of the coolant supplied to the cylinder head, an impeller pulley for driving the impeller, and a belt for transmitting the rotational force of the water pump pulley to the impeller pulley. It is done.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.

제1도는 본 고안에 의한 엔진냉각성능 향상장치를 나타내는 도면으로 도면중부호 1은 실린더블록이며 부호 5와 6은 실린더블록(1)에 형성되어 실린더 라이너(3)(4)를 둘러싸고 있는 워터재킷이다.1 is a view showing an engine cooling performance improving apparatus according to the present invention, wherein 1 is a cylinder block and 5 and 6 are formed in the cylinder block 1 to surround a water liner 3 and a cylinder liner 3. to be.

상기 실린더블록(1)의 워터재킷(5)(6) 입구부에는 워터펌프(7)가 설치되어 있으며 그와는 다른 위치의 워터재킷(5)(6) 내에는 임펠러(8)(9)가 설치되어 있다.A water pump (7) is installed at the inlet of the water jacket (5) and (6) of the cylinder block (1), and the impeller (8) (9) is in the water jacket (5) (6) at a different position. Is installed.

상기 임펠러(8)(9)를 구동하기 위한 임펠러용 풀리(10)(11)와 워터펌프(7)의 풀리(12)는 벨트(13)(14) 또는 체인으로 연결되어 크랭크축이 회전하게 되면 벨트(15)에 의해 풀리(12)가 회전하게되며, 이에따라 워터펌프(7)가 회전구동되어 라디에이터측 또는 서모스탯측과 접속되는 유입구(16)를 통해 냉각수를 흡입하여 워터재킷(5)(6)내로 강제 송출하게 된다.The impeller pulleys 10 and 11 for driving the impellers 8 and 9 and the pulleys 12 of the water pump 7 are connected by belts 13 and 14 or a chain to rotate the crankshaft. When the pulley 12 is rotated by the belt 15, the water pump 7 is rotated accordingly to suck the cooling water through the inlet port 16 connected to the radiator side or the thermostat side to the water jacket (5) (6) It is forcibly sent out.

이때 풀리(12)와 각각 벨트(13)(14)로 연결된 풀리(10)(11) 및 임펠러(8)(9)도 회전하게 되어 냉각수의 유속을 증가시켜 실린더 블록(1)으로부터 실린더헤드 측으로 냉각수의 흐름이 원활하도록 하여 냉각성능을 향상시키게 된다.At this time, the pulleys 10 and 11 and the impeller 8 and 9, which are connected to the pulley 12 and the belts 13 and 14, respectively, are also rotated to increase the flow rate of the coolant to the cylinder head 1 from the cylinder block side. The cooling water flows smoothly to improve the cooling performance.

이와같은 구조의 본 고안은 실린더가 좌우측에 V자형으로 배치되는 V6 엔진에 특히 적합히다.The present invention of such a structure is particularly suitable for a V6 engine in which the cylinders are arranged in a V shape on the left and right sides.

이상과 같은 본 고안에 의하면 기존의 워터펌프에 실린더블록의 냉각수 입구부의 2개소에 임펠러가 연동되도록 설치하여 임펠러가 워터펌프와 함께 구동하여 냉각수를 송출하도록 하는 것에 의해서 실린더블록을 거쳐 실린더헤드에 공급되는 냉각수의 유속을 증가시기게 되므로써 엔진의 냉각성능을 향상시키게 되며 배기가 저감 효과와 함께 윤활계의 온도상승 방지로 내구성을 증과시키게 되는 효과가 있다.According to the present invention as described above, the impeller is interlocked with the existing water pump at two locations of the cooling water inlet of the cylinder block, and the impeller is driven together with the water pump to supply the coolant to be supplied to the cylinder head via the cylinder block. By increasing the flow rate of the cooling water, the cooling performance of the engine is improved, and the exhaust gas is reduced and the durability is increased by preventing the temperature rise of the lubrication system.
