본 고안은 선박용 엔진의 과열을 방지하기 위하여 열교환기를 이용한 선박용 엔진의 냉각장치에 관한 것으로, 특히 해수를 유입하여 순환시키는 열교환기에 의해 엔진냉각수를 냉각시켜 주므로서 엔진냉각수의 냉각효율을 증대하고, 해수의 통과로 인한 배기관의 부식을 방지할 수 있도록 한 것이다.The present invention relates to a cooling device for a marine engine using a heat exchanger to prevent overheating of the marine engine, and in particular, by increasing the cooling efficiency of the engine coolant by cooling the engine coolant by a heat exchanger for introducing and circulating sea water, It is to prevent corrosion of the exhaust pipe due to the passage of gas.

종래의 냉각장치를 살펴보면 도면 제 3 도에서와 같이 해수펌프(300)에 의해 여과기(100) 및 킹스톤 밸브(200)를 걸쳐 유입되는 해수가 엔진의 전방에 취부되는 열교환기(400)로 (2-Pass)하여 배기관(500) 및 선박용 기어 오일 냉각기(600)를 걸쳐 열교환된 해수가 배수되고, 청수펌프(700)에 의해 순환되는 청수는 열교환기(400)를 걸쳐 냉각된 청수가 오일냉각기(800) 및 엔진본체(900)를 걸쳐 냉각수 파이프(1000)를 지나 온도 감지기(1100)에서 그 청수의 온도에 따라 바이패스 시키거나 열교환기(400)를 걸쳐 청수를 냉각시켜 청수펌프(700)로 순환되게 하는 것이었다.Referring to the conventional cooling apparatus, as shown in FIG. 3, seawater flowing in through the filter 100 and the kingston valve 200 by the seawater pump 300 is mounted to the heat exchanger 400 mounted to the front of the engine (2). The fresh water circulated by the fresh water pump 700 is drained through the exhaust pipe 500 and the ship's gear oil cooler 600, and the fresh water circulated by the fresh water pump 700 passes through the heat exchanger 400. 800 and the engine body 900 through the coolant pipe 1000, the temperature sensor 1100 by bypass according to the temperature of the fresh water or cool the fresh water over the heat exchanger 400 to the fresh water pump 700 It was to be circulated.

그러나 이러한 종래의 방식은 배기관(500)내로 해수가 지나는 냉각방식이므로 배기관 벽의 부식으로 배기가스 통로에 해수가 침입되어 실린더 내부를 통해 오일팬의 오일과 해수가 섞여 엔진의 오일회로를 부식시키는 사태가 발생되어 엔진을 사용할 수 없게 되는 문제점이 발생되기 때문에 배기관 내에 해수에 의한 부식을 방지하기 위한 수단으로 Zn 에노우드(anode)를 사용하여 2∼3개월에 1회씩 교환하도록 했으나, 사용자의 부주의로 Zn에 애노우드가 소모된 후에도 계속 사용하므로서 배기관의 부식발생이 비일비재한 것이며, 또한 열교환기(400)의 취부 위치가 엔진의 전방에 취부되기 때문에 기관실의 활용공간이 작아지게 되며, 동력 취출장치 부착시 커플링의 길이가 길어지기 때문에 엔진의 고장을 유발하는 문제점이 야기되는 것이었다.However, since the seawater passes through the exhaust pipe 500, the seawater enters the exhaust gas passage due to the corrosion of the exhaust pipe wall, and the oil circuit of the oil pan and the seawater mix through the cylinder to corrode the oil circuit of the engine. Has occurred and the engine cannot be used, so Zn anode was used every two to three months as a means to prevent corrosion by seawater in the exhaust pipe. Corrosion occurs in the exhaust pipe as it continues to be used even after the anode is consumed in Zn, and since the mounting position of the heat exchanger 400 is mounted in front of the engine, the utilization space of the engine room is reduced, and a power take-off device is attached. The long length of the sea coupling caused the engine to fail.
