Cooled by heat exchange with fresh water, the oil and fresh water passing through the oil cooler is also cooled by secondary by the cooling water filled in the auxiliary tank to significantly improve the cooling efficiency of the fresh water and oil as well as the engine The present invention relates to a heat exchanger for a marine engine that can be compact.

일반적으로 통상적인 선박 엔진용 냉각 장치는 크게 청수냉각 방식과 해수냉각 방식으로 두 가지 방식으로 구분되며, 상기 청수냉각 방식에 의한 선박 엔진용 냉각 장치에 사용되는 선박 엔진용 열교환기로는 통상적으로 청수 쿨러가 사용된다.In general, a ship engine cooling apparatus is generally divided into two types, a fresh water cooling method and a sea water cooling method. As a heat exchanger for a ship engine used in a cooling device for a ship engine by the fresh water cooling method, a fresh water cooler is usually used. Is used.

도 1 은 통상적인 선박 엔진용 열교환기로 사용되는 청수 쿨러의 정단면도로서, 도 1에 도시된 바와 같이 통상적인 청수 쿨러(10)는 원통 형상의 하우징(100); 상기 하우징(100) 내부에 설치되는 다수개의 열교환 튜브(101); 상기 하우징(100)의 상단부에 설치되는 보조탱크(102); 상기 하우징(100)의 양측단에 설치되는 한 쌍의 커버(103)를 포함하여 구성된다.1 is a cross sectional front view of a fresh water cooler used as a heat exchanger for a conventional marine engine. As shown in FIG. 1, a typical fresh water cooler 10 includes a cylindrical housing 100; A plurality of heat exchange tubes (101) installed inside the housing (100); An auxiliary tank 102 installed at an upper end of the housing 100; It is configured to include a pair of covers 103 installed on both ends of the housing 100.

또한, 도 2 는 통상적인 청수 쿨러가 설치된 선박 엔진용 냉각 장치의 회로도로서, 도 2에 도시된 바와 같이 종래의 통상적인 청수 쿨러(10)는 제 1 공급라인(9b)에 의해 온도감지기(3) 및 청수 펌프(4)와 연결되며, 상기 온도감지기(3)와 청수 펌프(4)는 바이 패스라인(9)에 의해 연결된다. 또한 상기 온도감지기(3)와 청수 펌프(4)는 오일 쿨러(12)를 거쳐 엔진(2) 내부를 순환하는 제 2 공급라인(9a)에 의해 연결된다. 또한 상기 청수 쿨러(10)는, 일측 끝단부는 선박용 기어오일 쿨러(8)와 연결되며 타측은 해수 펌프(5), 킹스톤 밸브(6) 및 여과기(7)와 순차적으로 연결된 해수 공급라인(9c)과 연결된다.FIG. 2 is a circuit diagram of a cooling system for a marine engine provided with a conventional fresh water cooler, and as shown in FIG. 2, the conventional fresh water cooler 10 includes a temperature sensor 3 by a first supply line 9b. And the fresh water pump 4, the temperature sensor 3 and the fresh water pump 4 are connected by a bypass line 9. In addition, the temperature sensor 3 and the fresh water pump 4 are connected by a second supply line 9a circulating inside the engine 2 via the oil cooler 12. In addition, the fresh water cooler 10, one end is connected to the marine gear oil cooler (8) and the other side is a sea water supply line (9c) sequentially connected to the seawater pump (5), Kingston valve (6) and filter (7) Connected with

상기와 같은 선박 엔진용 냉각 장치는 청수의 온도에 따라 선택적으로 청수 펌프(4)의 펌핑력으로 청수가 제 2 공급라인(9a)을 통해 오일 쿨러(12)를 거친 후 엔진(2) 내부로 유입되어 엔진(2)을 냉각시킨 다음 엔진(2)을 빠져나와 온도감지기(3)로 유입되도록 순환되거나, 제 1 공급라인(9b)을 통해 보조탱크(102)를 거쳐 청수 쿨러(10)로 공급된 후 청수 펌프(4)에 의해 제 2 공급라인(9a)을 통해 오일 쿨러(12)를 거쳐 엔진(2)으로 유입되어 엔진(2)을 냉각시킨 후 온도감지기(3)에 도달하게 되는 순환을 반복하게 된다.As described above, the cooling device for the ship engine is selectively pumped by the fresh water pump 4 according to the temperature of the fresh water. The fresh water passes through the oil cooler 12 through the second supply line 9a and then into the engine 2. Flows to cool the engine 2 and then exits the engine 2 and circulates to enter the temperature sensor 3 or through the auxiliary tank 102 through the first supply line 9b to the fresh water cooler 10. After being supplied, the fresh water pump 4 enters the engine 2 through the oil cooler 12 through the second supply line 9a, cools the engine 2, and reaches the temperature sensor 3. The cycle will repeat.

이때, 제 1 공급라인(9b)을 통해 보조탱크(102)를 경유한 후 청수 쿨러(10)로 유입되는 청수는 해수 펌프(5)의 작동으로 인하여 여과기(7) 및 킹스톤 밸브(6)를 순차적으로 거쳐 해수 공급라인(9c)을 통해 청수 쿨러(10)로 유입되는 해수와 열 교환되며, 상기와 같이 열 교환된 청수는 청수 펌프(4)의 작동에 따라 제 2 공급라인(9a)을 통해 오일 쿨러(12)를 거쳐 열 교환된 후 다시 엔진(2)으로 유입되어 엔진(2)을 냉각시키게 되고, 해수 공급라인(9c)을 통해 청수 쿨러(10)로 유입되어 청수와 열 교환된 해수는 선박용 기어오일 쿨러(8)를 통해 배출된다.At this time, the fresh water flowing into the fresh water cooler 10 after passing through the auxiliary tank 102 through the first supply line 9b is connected to the filter 7 and the kingston valve 6 due to the operation of the sea water pump 5. Through the sea water supply line (9c) is sequentially exchanged with the sea water flowing into the fresh water cooler 10, the fresh water heat exchanged as described above is the second supply line (9a) in accordance with the operation of the fresh water pump (4) After the heat exchange through the oil cooler (12) through the engine (2) again to cool the engine (2), through the sea water supply line (9c) to the fresh water cooler (10) is heat exchanged with fresh water Seawater is discharged through the ship gear oil cooler (8).

그러나 상기와 같은 종래의 선박 엔진용 열교환기는 청수 쿨러(10)와 오일 쿨러(12)가 별도로 설치되어 선박 엔진용 열교환기의 부피가 커짐으로 인하여 엔진(2) 설치를 위한 공간 활용이 매우 어려우며, 오일 쿨러(12)를 별도로 설치함에 따라 긴 배관을 설치해야 함으로써 제작비용이 증가될 뿐만 아니라, 오일 쿨러(12)를 단순히 엔진(2)의 전방부에 설치하게 됨으로써 오일 쿨러(12)의 냉각효율이 좋지 않다는 문제점이 있었다.However, the conventional heat exchanger for ship engines as described above has a fresh water cooler 10 and an oil cooler 12 installed separately, which makes it difficult to utilize space for installing the engine 2 due to the increase in the volume of the heat exchanger for ship engines. As the oil cooler 12 is separately installed, the production cost is increased by installing a long pipe, and the oil cooler 12 is simply installed at the front of the engine 2, thereby cooling the oil cooler 12. There was a problem that this was not good.

따라서 본 발명의 목적은 청수 및 오일의 냉각효율을 대폭 향상시킬 수 있도록 하는 선박 엔진용 열교환기를 제공하는 것이다. It is therefore an object of the present invention to provide a heat exchanger for a marine engine which can greatly improve the cooling efficiency of fresh water and oil.

도 4는 본 발명에 따른 일실시예에 의한 선박 엔진용 열 교환기가 설치된 선박 엔진용 냉각 장치의 회로도로서, 도 4에 도시된 바와 같이 본 발명에 따른 선박 엔진용 열교환기(1)의 청수 쿨러(10)는 제 1 공급라인(9b)에 의해 온도 감지기(3) 및 청수 펌프(4)와 연결되며, 상기 온도 감지기(3)와 청수 펌프(4)는 바이 패스라인(9)에 의해 연결된다. 또한 상기 온도 감지기(3)와 청수 펌프(4)는 오일 쿨러(12)를 거쳐 엔진(2) 내부를 순환하는 제 2 공급라인(9a)에 의해 연결된다. 또한 상기 청수 쿨러(10)는, 일측 끝단부는 선박용 기어오일 쿨러(8)와 연결되며 타측은 해수 펌프(5), 킹스톤 밸브(6) 및 여과기(7)와 순차적으로 연결된 해수 공급라인(7c)과 연결된다.FIG. 4 is a circuit diagram of a ship engine cooling apparatus in which a ship engine heat exchanger is installed according to an embodiment of the present invention. As shown in FIG. 4, a fresh water cooler of the ship engine heat exchanger 1 according to the present invention. 10 is connected to the temperature sensor 3 and the fresh water pump 4 by a first supply line 9b, wherein the temperature sensor 3 and the fresh water pump 4 are connected by a bypass line 9. do. The temperature sensor 3 and the fresh water pump 4 are also connected by a second supply line 9a which circulates inside the engine 2 via the oil cooler 12. In addition, the fresh water cooler 10, one end is connected to the marine gear oil cooler (8) and the other side is a seawater supply line (7c) sequentially connected to the seawater pump (5), Kingston valve (6) and filter (7) Connected with

상기와 같이 연결되어 구성된 선박 엔진용 냉각 장치는 엔진의 초기 시동 시에는 청수 펌프(10)의 펌핑력으로 청수가 제 2 공급라인(7a)을 통해 오일 쿨러(12)를 거친 후 엔진(2) 내부로 유입되어 엔진(2)을 냉각시킨 다음 엔진(2)을 빠져나와 온도감지기(3)에 도달하게 된다.The cooling device for a marine engine configured as described above is connected to the engine 2 after the fresh water passes through the oil cooler 12 through the second supply line 7a by the pumping force of the fresh water pump 10 at the initial start of the engine. After entering the interior, the engine 2 is cooled and then exits the engine 2 to reach the temperature sensor 3.

이때 온도감지기(3)는 엔진(2)의 초기 시동 시 청수의 온도가 저온이므로 청수의 온도를 높이기 위해 바이패스 라인(9)을 개방시켜 청수가 청수 펌프(4)를 거쳐 제 2 공급라인(9a)을 통해 오일 쿨러(12)를 거친 후 엔진(2) 내부로 재 유입되어 엔진(2)을 냉각시킬 수 있도록 재순환시키게 된다.At this time, since the temperature of the fresh water is low at the initial start of the engine 2, the temperature sensor 3 opens the bypass line 9 to increase the temperature of the fresh water so that the fresh water passes through the fresh water pump 4 to supply the second supply line ( After passing through the oil cooler 12 through 9a) it is re-introduced into the engine 2 and recycled to cool the engine 2.

상기와 같이 청수가 제 2 공급라인(9a)을 통해 오일 쿨러(12)를 거친 후 엔진(2) 내부로 유입되는 순환이 반복되어 청수의 온도가 상승하게 되어 설정 온도 값에 도달하게 되면, 온도감지기(3)는 바이패스 라인(9)을 패쇄시키게 되며, 이에 따라 청수는 제 1 공급 라인(9b)을 통해 보조 탱크(102)를 거쳐 청수 쿨러(10)로 공급된 후 청수 펌프(4)에 의해 제 2 공급라인(7a)을 통해 오일 쿨러(12)를 거쳐 엔진(2)으로 유입되어 엔진(2)을 냉각시킨 후 온도감지기(3)에 도달하게 되는 순환을 반복하게 된다.As described above, after the fresh water passes through the oil cooler 12 through the second supply line 9a and the circulation flowing into the engine 2 is repeated, the temperature of the fresh water rises to reach the set temperature value. The detector 3 closes the bypass line 9 so that fresh water is supplied via the first supply line 9b to the fresh water cooler 10 via the auxiliary tank 102 and then to the fresh water pump 4. By the second supply line (7a) through the oil cooler 12 to enter the engine 2 to cool the engine (2) is repeated to reach the temperature sensor (3).

상기 제 1 공급라인(9b)을 통해 보조탱크(102)를 경유한 후 청수 쿨러(10)로 유입되는 청수는 해수 펌프(5)의 작동으로 인하여 여과기(7) 및 킹스톤 밸브(6)를 순차적으로 거쳐 해수 공급라인(9c)을 통해 청수 쿨러(10)로 유입되는 해수와 열 교환되며, 상기와 같이 열 교환된 청수는 청수 펌프(4)의 작동에 따라 제 2 공급라인(9a)을 통해 오일 쿨러(12)를 거쳐 열 교환된 후 다시 엔진(2)으로 유입되어 엔진(2)을 냉각시키게 되고, 해수 공급라인(9c)을 통해 청수 쿨러(10)로 유입되어 청수와 열 교환된 해수는 선박용 기어오일 쿨러(8)를 통해 배출된다.The fresh water flowing into the fresh water cooler 10 after passing through the auxiliary tank 102 through the first supply line 9b sequentially passes through the filter 7 and the kingston valve 6 due to the operation of the sea water pump 5. Through the sea water supply line (9c) through the heat exchange with the seawater flowing into the fresh water cooler 10, the fresh water exchanged as described above through the second supply line (9a) in accordance with the operation of the fresh water pump (4) After the heat exchange through the oil cooler (12) is introduced into the engine (2) to cool the engine (2), the seawater flowing into the fresh water cooler (10) through the sea water supply line (9c) and heat exchanged with fresh water Is discharged through the ship gear oil cooler (8).

이때 상기 오일 쿨러(12)는 냉각수가 충진된 보조탱크(102) 내부에 설치됨으로써 상기 오일 쿨러(12) 내부로 유입되는 오일은 1차적으로 제 2 공급라인(9a)을 통해 오일 쿨러(12)로 유입되는 청수와 열 교환되며, 상기 오일 쿨러(12)를 통과하는 오일과 청수 또한 보조탱크(102) 내부에 충진된 냉각수에 의해 2차적으로 냉각됨으로써 오일 쿨러(12)의 냉각 효율을 대폭 향상시킬 수 있도록 한다. At this time, the oil cooler 12 is installed in the auxiliary tank 102 filled with the coolant, so that the oil flowing into the oil cooler 12 is primarily the oil cooler 12 through the second supply line 9a. The oil and fresh water passing through the oil cooler 12 and the second water are also secondarily cooled by the cooling water filled in the auxiliary tank 102, thereby greatly improving the cooling efficiency of the oil cooler 12. Make it work.

즉, 상기와 같은 본 발명에 따른 일실시예에 의한 선박 엔진용 열교환기(1)는 청수 쿨러(10)의 보조탱크(102) 내부에 오일 쿨러(12)가 설치됨으로써 상기 오일 쿨러(12) 내부로 유입되는 오일이 1차적으로 제 2 공급라인(9a)을 통해 오일 쿨러(12)로 유입되는 청수와 열 교환되어 냉각시킬 수 있으며, 상기 오일 쿨러(12)를 통과하는 오일과 청수 또한 보조탱크(102) 내부에 충진된 냉각수에 의해 2차적으로 냉각됨으로써 오일 쿨러(12)의 냉각 효율을 대폭 향상시킬 수 있을 뿐만 아니라 오 일 쿨러(12)를 별도로 설치하지 않아도 됨으로써 설치 작업성의 향상은 물론 배관이 단축되어 제작비용의 절감과 엔진(2)의 컴팩트화를 꾀할 수 있으므로 엔진(2) 설치를 위한 공간 활용의 효과가 있다.That is, in the ship engine heat exchanger 1 according to the embodiment of the present invention as described above, the oil cooler 12 is installed by installing the oil cooler 12 inside the auxiliary tank 102 of the fresh water cooler 10. The oil flowing into the inside may be cooled by heat exchange with fresh water flowing into the oil cooler 12 through the second supply line 9a, and the oil and fresh water passing through the oil cooler 12 may also be assisted. Secondary cooling by the coolant filled in the tank 102 not only improves the cooling efficiency of the oil cooler 12 significantly, but also does not require the oil cooler 12 to be installed, thereby improving installation workability. Since the pipe is shortened, the manufacturing cost can be reduced and the engine 2 can be made compact, so that space for the engine 2 can be used.

이상, 상술한 바와 같이 본 발명에 따른 선박 엔진용 열교환기는 청수 쿨러의 보조 탱크 내부에 오일 쿨러가 설치됨으로써 상기 오일 쿨러 내부로 유입되는 오일이 1차적으로 제 2 공급라인을 통해 오일 쿨러로 유입되는 청수와 열 교환되어 냉각시킬 수 있으며, 상기 오일 쿨러를 통과하는 오일과 청수 또한 보조 탱크 내부에 충진된 냉각수에 의해 2차적으로 냉각됨으로써 청수 및 오일의 냉각 효율을 대폭 향상시킬 수 있을 뿐만 아니라 오일 쿨러를 별도로 설치하지 않아도 됨으로써 설치 작업성의 향상은 물론 배관이 단축되어 제작비용의 절감과 엔진의 컴팩트화를 꾀할 수 있으므로 엔진 설치를 위한 공간 활용의 효과가 있어 매우 유용한 발명인 것이다.As described above, the heat exchanger for the ship engine according to the present invention, as the oil cooler is installed in the auxiliary tank of the fresh water cooler, inflows into the oil cooler primarily through the second supply line. Cooled by heat exchange with fresh water, the oil and fresh water passing through the oil cooler is also cooled by the secondary coolant filled in the auxiliary tank, which can greatly improve the cooling efficiency of the fresh water and oil as well as the oil cooler. It is a very useful invention because it does not need to be installed separately, as well as improving the installation workability, as well as shortening the piping can reduce the production cost and compact the engine, so that the space utilization for the engine installation is effective.
