본 고안은 선박용 엔진의 과열방지를 위한 열교환기용 배기 매니홀드에 관한 것으로, 특히 열교환기와 배기 매니 홀드를 각각 따로 설치하던 것을 일체화 시키므로서 부품을 소형화시키고 냉각 효율을 향상시키도록 한 것이다.The present invention relates to an exhaust manifold for a heat exchanger for preventing overheating of a marine engine, and in particular, to miniaturize parts and improve cooling efficiency by integrating a heat exchanger and an exhaust manifold separately.

종래에는 제1도에서 보는 바와같이 열교환기(1)와 배기 매니홀드(2)가 각각 따로 취부되고 클링 파이프로 각 냉각부에 연결된 것으로서 해수펌프(3)에 의해 펌핑되는 해수가＂→＂와 같이 곧바로 열교환기(1)로 연결되어 열교환기(1)로부터 엔진 본체를 순회하는 동안 뜨거워진 청수를 식힌 다음 배기 매니홀드(2)의 쟈켓 부분을 통하여 배기 매니홀드(2)를 식히고, 다시 마린기어 오일쿨러(4)를 식힌 후 밖으로 배출되는 것이었다.Conventionally, as shown in FIG. 1, the heat exchanger 1 and the exhaust manifold 2 are separately mounted and connected to each cooling unit by a clinking pipe, and the seawater pumped by the seawater pump 3 Likewise, it is directly connected to the heat exchanger (1) to cool the hot fresh water while circulating the engine body from the heat exchanger (1), and then cools the exhaust manifold (2) through the jacket portion of the exhaust manifold (2), and again After cooling the gear oil cooler (4) was discharged out.

또한, ＂－－→＂로 표시된 라인은 청수의 순환경로를 나타낸 것으로서 엔진이 작동하면 열교환기(1) 탱크에 있는 청수를 빨아들여 실린더 헤드의 쟈켓부와 실린더 몸체의 쟈켓부를 냉각시킨 다음 써모스타트(5)를 거쳐 열교환기 탱크로 순환되고, 일부(90℃ 미만의 물)는 곧바로 청수펌프(6)로 순환되는 것이었다.In addition, the line marked ＂-－ →＂ shows the circulation path of fresh water, and when the engine is operated, the fresh water in the tank of the heat exchanger (1) is sucked in to cool the jacket part of the cylinder head and the jacket part of the cylinder body, and then the thermostat It circulated to the heat exchanger tank via (5), and some (water below 90 degreeC) was immediately circulated to the fresh water pump 6.

그러나, 이와같은 종래의 구성은 배기 매니홀드(2)와 열교환기(1)가 각기 따로 설치되어 있기 때문에 부품의 수가 많아 엔진이 복잡할뿐 아니라, 엔진 본체의 청수가 식혀주고 배기 매니홀드(2)는 해수가 식혀 주기 때문에 열교환기(1)내에 부식방지용 봉을 설치하지 않으면 쉽게 녹이 슬어 고장의 원인이 되는 문제점이 있었던 것이다.However, such a conventional configuration is that the exhaust manifold 2 and the heat exchanger 1 are provided separately, so that the number of parts is not only complicated, but also the engine is complicated, and the fresh water of the engine body is cooled, and the exhaust manifold 2 ), Because the sea water cools, if the corrosion prevention rod is not installed in the heat exchanger (1), there was a problem that easily rusted, causing failure.

따라서, 본 고안은 이와 같은 종래의 제반 문제점을 해소하기 위하여 열교환기와 배기 매니홀드를 일체로 구성하므로서 원가를 줄였고, 청수로서 엔진 본체와 배기 매니홀드를 냉각시켜 주므로서 부식을 방지할수 있도록 한 것으로 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Therefore, the present invention reduces the cost by integrally configuring the heat exchanger and the exhaust manifold to solve such a conventional problem, and to prevent corrosion by cooling the engine body and the exhaust manifold with fresh water. When described in detail with reference to the drawings as follows.

제2도와 제3도에서해수흐름 방향,청수 흐름방향, →배기가스 토출방향이고, A, B, C, D는 배기가스 구멍(port)이다.In Figures 2 and 3 Sea Flow Direction, Fresh water flow direction, → exhaust gas discharge direction, and A, B, C, and D are exhaust gas ports.

내부에 격벽(7)을 형성하여 좌측홀(8)과 우측홀(9)을 갖도록 하고, 우측홀(9)의 후면에 청수유입구(10)와 좌측홀(8)에 청수유출구(11)를 형성하여서된 배기 매니홀드(12)로 안쪽 공간에 수개의 해수통로 파이프(13)로 구성된 열교환기(14)를 내설한 후 해수 입구(15)와 해수출구(16)에 고무블록(17)을 클림핑힌다. 열교환기(14)에는 양측으로 타원형의 청수입구(18)과 청수출구(19)를 형성하여 청수입구(18)는 우측홀(9)에 청수출구(19)는 좌측홀(8)에 위치토록 한 것이다.A partition 7 is formed inside to have a left hole 8 and a right hole 9, and a fresh water outlet 11 is provided at a fresh water inlet 10 and a left hole 8 at the rear of the right hole 9. After forming a heat exchanger (14) composed of several seawater passage pipes (13) in the inner space with the formed exhaust manifold (12), a rubber block (17) is provided at the seawater inlet (15) and the seawater outlet (16). Climping. The heat exchanger 14 has elliptical fresh water inlets 18 and fresh water outlets 19 on both sides, so that the fresh water inlets 18 are in the right hole 9 and the fresh water outlets 19 are in the left hole 8. It is.

도면중 미설명 부호 20은 배기 가스출구 벽면이고, 21는 휠러캡이다.In the figure, reference numeral 20 denotes an exhaust gas outlet wall surface, and 21 denotes a wheeler cap.

이와같은 본 고안은 해수입구(15)를 해수펌프(3)의 출구와 연결하고 해수출구(16)는 마린기어 오일쿨러(4)와 연결되며, 청수유출구(11)는 청수펌프(6)와 연결되어 있는 구성으로서 해수의 흐름은 제2도에서 보는바와 같이 해수펌프(3)에서 펌핑된 해수가 해수입구(15)를 통해 곧바로 열교환기(14)의 해수통로파이프(13)들을 통과하여 해수출구(16)을 거친 다음 마린기어 오일쿨러(4)를 통해 밖으로 배출되어지는 것이다.The present invention connects the seawater inlet 15 to the outlet of the seawater pump 3, and the seawater outlet 16 is connected to the marine gear oil cooler 4, and the freshwater outlet 11 is connected to the freshwater pump 6. As shown in FIG. 2, the seawater flows through the seawater channel pipes 13 of the heat exchanger 14 through the seawater inlet 15 through the seawater inlet 15 as shown in FIG. After passing through the outlet 16, it is discharged out through the marine gear oil cooler (4).

또한, 청수흐름은 청수펌프가 작동하므로서 배기 매니홀드(12) 즉, 홀(9)에 채워져 있는 청수가 청수펌프(6)를 통하여 실린더 헤드 몸체와 실린더 몸체를 식히게 되는 것이고, 그런다음 90℃ 이상되는 청수는 써모스타트(5)를 통하여 배기 매니홀드(12)의 청구유입구(10)를 통해 우측홀(9)로 유입된 후 열교환기(14)의 청수입구(18)로부터 청수출구(19)를 통하여 좌측홀(8)로 유입된 다음 청수펌프(16)로 순환되어지는 것이다.In addition, the fresh water flow is to cool the cylinder head body and the cylinder body through the fresh water pump 6, which is filled in the exhaust manifold 12, that is, the hole 9 as the fresh water pump is operated, and then the 90 ° C The abnormal fresh water flows into the right hole 9 through the charge inlet 10 of the exhaust manifold 12 through the thermostat 5 and then from the fresh water inlet 18 of the heat exchanger 14. Into the left hole (8) is then circulated to the fresh water pump (16).

이때, 열교환기(14)는 수개의 해수통로 파이프(13)로 구성되어 있고, 양측으로 타원형의 청수입구(18)와 청수출구(19)가 형성되어 있기 때문에 청수는 청수입구(18)를 통해 수개의 해수통로 파이프(13) 사이들을 지나 청수출구(19)로 나오게 되는 것이다.At this time, the heat exchanger 14 is composed of several seawater passage pipes 13, and since the oval fresh water inlet 18 and the fresh water outlet 19 are formed at both sides, the fresh water is supplied through the fresh water inlet 18. Several seawater passages between the pipes (13) is to come out to the fresh water outlet (19).

여기서 배기 매니홀드(12)내의 뜨거워진 청구가 곧바로 홀(9)로 흐르지 않도록 반드시 분리격판(7)을 형성하여야만 높은 청수 냉각효과를 얻을 수 있는 것이며, 이때 주의할 점은 열교환기(14)와 배기 매니홀드(12)의 배기가스 출구 벽면(20)사이가 20㎜이상 떨어지면 냉각수의 온도가 해수의 온도와 큰 차이가 없으므로 엔진의 성능에 영향을 초래할 우려가 있는 것이다.In this case, the separation plate 7 must be formed so that the hot bill in the exhaust manifold 12 does not flow directly into the hole 9, so that a high fresh water cooling effect can be obtained. If the distance between the exhaust gas outlet wall surface 20 of the exhaust manifold 12 is 20 mm or more, the temperature of the cooling water is not significantly different from the temperature of the sea water, which may affect the performance of the engine.

이와 같이 된 본 고안은 열교환기(14)와 배기 매니홀드(12)를 일체화 시키므로서 엔진의 장착 공간이 좁아지고 부품수가 적어지게 되어 원가를 절감시킬 수 있을 뿐 아니라, 이들을 연결하는 냉각 파이프를 없앨수가 있으며, 종래의 열교환기가 녹슬지 않도록 부식 방지봉을 설치해야만 했던 것을 양측으로 고무블록을 클램핑 하므로서 해수와 청수가 완전 분리되어져 부식 방지봉을 설치할 필요가 없게 되는 것이다.In this way, the present invention integrates the heat exchanger 14 and the exhaust manifold 12 so that the mounting space of the engine is narrowed and the number of parts is reduced, thereby reducing the cost and eliminating the cooling pipe connecting them. There is no need to install the corrosion protection rods by completely separating the sea water and fresh water by clamping the rubber block to both sides that had to install the corrosion protection rods to prevent the heat exchanger to rust.

또한, 청수 냉각으로 배기 매니홀드가 부식이 되지 않아 수명이 길어지게 되고, 냉각 효율을 높일 수가 있으므로 엔진의 과열을 방지하게 되는 유용한 고안이다.In addition, since the fresh water cooling does not corrode the exhaust manifold, the life is long, and the cooling efficiency can be increased, which is a useful design to prevent overheating of the engine.
