Description

수냉엔진의 냉각수 정화장치Cooling water purification device of water cooling engine

본 발명은 수냉엔진의 냉각수에 함유되어 있는 금속분 등의 이물질을 여과하여 냉각수의 청정화를 이룰 수 있도록 한 수냉엔진의 냉각수 여과장치에 관한 것이다.The present invention relates to a cooling water filtration device for a water cooling engine that filters foreign matters such as metal powder contained in the cooling water of a water cooling engine to clean the cooling water.

일반적으로 수냉엔진은 그 조립공정 전에 세척을 하더라도 워터재킷의 내벽에 붙어 있는 주물사와 연마가공 등에 의해 발생되는 금속분 등의 이물질이 완전히 제거되지 않은 상태로 조립되고 있다.In general, even if the water-cooled engine is washed before the assembling process, foreign matters such as metal sand generated by the molding sand and the grinding process, etc., attached to the inner wall of the water jacket are not completely removed.

종래 기술의 냉각수 순환계통에는 수냉엔진 조립후 워터재킷의 내벽에 붙어 있게 되는 금속분 등의 이물질을 여과, 제거할 수 있는 장치가 설치되어 있지 않기 때문에 엔진의 냉각수 순환계통에 상기한 이물질이 혼입된 상태에서 냉각수가 순환하게 되면 여러 가지의 문제점을 야기시키게 된다.The above-mentioned cooling water circulation system is not equipped with a device capable of filtering and removing foreign substances such as metal powder which is attached to the inner wall of the water jacket after assembling the water cooling engine. The circulation of coolant in the water causes several problems.

즉, 냉각수에 혼입된 이물질은 워터펌프의 펌핑작동시 워터펌프 내부로 유입되게 되며, 이렇게 유입된 이물질은 워터펌프의 밀봉수단인 메탈시일부재의 밀봉습동면 사이에 끼이게 되어 메탈시일부재의 이상마모, 편마모 또는 면거칠어짐 현상을 일으켜 밀봉기능을 저하시킴과 동시 사용수명을 단축시키는 문제점이 있었으며, 또한 냉각수가 서모스탯(Thermostat)을 경유할 때 이물질이 밸브 외주연과 밸브 구경 사이에 침투하여 서모스탯의 기능을 저하시켜 초기시동시에도 저온상태의 냉각수가 라디에이터로 순환되게 하는 문제점을 발생시키게 되며, 이렇게 저온의 냉각수가 라디에이터로 순환하게 될 경우에는 난기지연을 초래시켜 냉각수가 오버 쿨링(Over-Cooling)되는 현상이 나타나 결국 연비의 저하와 함께 난방성을 저하시켜 결국에는 환경오염을 유발시키게 되는 문제점이 있었다.That is, the foreign matter mixed in the cooling water is introduced into the water pump during the pumping operation of the water pump, and the foreign matter thus introduced is caught between the sealing sliding surfaces of the metal seal member, which is a sealing means of the water pump, so that the abnormality of the metal seal member is prevented. There was a problem of reducing the sealing function and shortening the service life by causing abrasion, wear, or surface roughness. Also, when the coolant passes through the thermostat, foreign matter penetrates between the valve outer periphery and the valve aperture. It lowers the function of the thermostat and causes a problem that the coolant in the low temperature state is circulated to the radiator even at the initial start-up.In this case, if the coolant at low temperature is circulated to the radiator, it causes an air delay and the overcooling -Cooling) appears, eventually lowering fuel efficiency and heating efficiency, eventually reducing environmental pollution There was a problem that thereby feet.

또한 냉각수가 라디에이터로 유동할 때 금속분의 이물질이 라디에이터의 방열수단인 라디에이터 코아(Radiator core)의 튜브 사이에 고착되어 냉각수의 유동을 차단하게 되어 오버 히팅(Over-Heating)현상을 유발시키는 등 냉각수 순환계통의 성능을 악화시키게 되는 문제점이 있었다.In addition, when the coolant flows to the radiator, foreign matters in the metal are stuck between the tubes of the radiator core, which is a heat radiating means of the radiator, to block the flow of the coolant, causing an over-heating phenomenon. There was a problem that deteriorated the performance of the system.

본 발명은 종래와 같은 제반 문제점을 일소하기 위하여 창출한 것으로, 냉각수의 순환계통에 금속분의 이물질을 여과하는 냉각수 정화장치를 장설하는 수단으로서 이물질이 여과, 제거된 청정한 냉각수만이 냉각수 순환계통을 유동할 수 있도록 하는데 목적을 두고 발명한 것이다.The present invention was created in order to eliminate the conventional problems, and as a means of installing a cooling water purifying device for filtering foreign matter of metal powder in the cooling water circulation system, only the clean coolant in which the foreign matter is filtered and removed flows through the cooling water circulation system. It was invented for the purpose of making it possible.

도면부호 1은 냉각수 정화장치를 나타내는 것으로, 상기 냉각수 정화장치(1)는 워터펌프(10)와 라디에이터(11) 사이에 배관되어 있는 냉각수 귀환라인(12) 상에 장설되어 있다.Reference numeral 1 denotes a cooling water purifier, and the cooling water purifier 1 is installed on the cooling water return line 12 that is piped between the water pump 10 and the radiator 11.

상기 냉각수 정화장치(1)는 유입구(2)가 일체로 형성된 제1 케이스(3)와 유출구(4a)가 형성되는 제2 케이스(5)를 조립시킨 것이며, 상기 냉각수 정화장치(1)의 분리실(6) 내벽에는 마그네틱(7)이 부착되어 있다.The cooling water purifier 1 is a combination of the first case 3 formed integrally with the inlet 2 and the second case 5 having the outlet 4a formed therein, and the cooling water purifying apparatus 1 is separated. A magnetic 7 is attached to the inner wall of the seal 6.

상기 제2 케이스(5)에 형성되는 유출구(4a)는 분리실(6) 내부에 장착되는 분리판(4)과 일체로 구성된 것이며, 상기 분리판(4)의 외주에는 다수의 통공(4b)과 확장부(4c)가 형성되어 있다.The outlet 4a formed in the second case 5 is integrally formed with the separating plate 4 mounted inside the separating chamber 6, and a plurality of through holes 4b are formed on the outer circumference of the separating plate 4. And an extension portion 4c are formed.

또한 상기의 확장부(4c) 내부에는 여과부재(8)가 내장되어 있다.In addition, the filtration member 8 is built in the expansion portion 4c.

상기와 같은 냉각수 정화장치(1)의 작용을 설명하기 위해 수냉엔진의 냉각수 순환계통을 간략하게 설명하면, 실린더블럭(13)과 실린더헤드(14)의 내부에는 워터재킷(15)이 형성되어 있으며, 상기 워터재킷(15)의 냉각수 유입구(15a)에는 워터펌프(10)가 연결되며, 냉각수 유출구(15b)에는 서모스탯(16)이 연결되어 있다.Briefly describing the cooling water circulation system of the water cooling engine in order to explain the operation of the cooling water purification device 1 as described above, the water jacket 15 is formed inside the cylinder block 13 and the cylinder head 14. The water pump 10 is connected to the cooling water inlet 15a of the water jacket 15, and the thermostat 16 is connected to the cooling water outlet 15b.

상기 서모스탯(16)에는 라디에이터(11)에 연결되는 냉각수 공급라인(17)과 워터펌프(10)에 연결되는 바이패스라인(18)이 설치되어 있다.The thermostat 16 is provided with a cooling water supply line 17 connected to the radiator 11 and a bypass line 18 connected to the water pump 10.

그리고 상기 냉각수 정화장치(1)와 워터펌프(10) 사이에는 안력센서(19)가 장설되어 있는데, 상기 압력센서(19)는 냉각수 정화장치(1)를 통과하여 순환하는 냉각수의 유동압력을 감지한 후 그 신호를 ECU(20)에 보내며, 상기 ECU(20)는 압력센서(19)로부터 보내온 신호를 받아 냉각수 귀환라인(12)과는 별도로 워터펌프(10)와 라디에이터(11)를 연결하고 있는 릴리프라인(21) 상에 장설된 절환밸브(22)를 개폐작동시키도록 구성하였다. 즉, 상기 ECU(20)는 냉각수 정화장치(1)를 통과한 냉각수의 유동압력이 설정치 이상일 경우에는 절환밸브(22)를 폐쇄작동시키는 것이며, 설정치 이하일 경우에는 절환밸브(22)를 개방작동시키는 것이다.And the eye sensor 19 is installed between the cooling water purification device 1 and the water pump 10, the pressure sensor 19 detects the flow pressure of the cooling water circulating through the cooling water purification device (1) After the signal is sent to the ECU 20, the ECU 20 receives the signal from the pressure sensor 19 to connect the water pump 10 and the radiator 11 separately from the coolant return line 12 The switching valve 22 installed on the relief line 21 is configured to open and close. That is, the ECU 20 closes the switching valve 22 when the flow pressure of the coolant passing through the cooling water purifier 1 is greater than or equal to the set value, and opens the switching valve 22 when the ECU is less than the set value. will be.

이와같이 구성된 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

엔진이 가동하게 되면 워터펌프(10)가 작동되게 되므로서 냉각수가 순환하게 되며, 냉각수가 설정온도(80∼85℃) 이하일 때에는 워터재킷(15)에서 유출되는 냉각수는 바이패스라인(18)을 통해 워터재킷으로 되돌아가며, 설정온도 이상일 경우에는 냉각수 공급라인(17)을 통해 라디에이터(11)를 경유하면서 열교환하여 냉각된 다음 냉각수 귀환라인(12)을 통해 워터재킷(15)으로 유입되는 과정에서 냉각수 정화장치(1)를 통과하게 된다.When the engine is running, the water pump 10 is operated so that the coolant circulates. When the coolant is below the set temperature (80 to 85 ° C.), the coolant flowing out of the water jacket 15 passes through the bypass line 18. Return to the water jacket through the heat exchanger via the radiator 11 through the cooling water supply line 17 when the temperature is higher than the set temperature, and then cools and then enters the water jacket 15 through the cooling water return line 12. Pass through the cooling water purification device (1).

상기 냉각수 정화장치(1)의 유입구(2)와 유출구(4a)는 대칭상태의 위치에 형성되어 있으므로서 상기 유입구(2)를 통해 유입되는 냉각수는 분리실(6)에서 소용돌이 작용으로 유동하게 되는 것이며, 이때 소용돌이치는 냉각수는 분리실(6) 내벽에 부착된 마그네틱(7)과 접촉하게 되는데, 이때 냉각수에 혼입되어 있는 금속분은 마그네틱(7)에 흡착되는 것이며, 금속분이 제거된 냉각수는 분리관(4)의 외주에 다수 천공되어 있는 통공(4b)를 통해 상기 분리관(4) 내부로 유입된 후 여과부재(8)를 통과하게 되는데, 상기 여과부재(8)는 냉각수에 혼입되어 있는 주물사 등의 이물질을 여과하기 때문에 유출구(4a)로 유출되는 냉각수는 깨끗이 정화된 상태로 되는 것이다.Since the inlet port 2 and the outlet port 4a of the coolant purification device 1 are formed in a symmetrical position, the coolant flowing through the inlet port 2 swirls in the separation chamber 6. At this time, the swirling cooling water is in contact with the magnetic (7) attached to the inner wall of the separation chamber (6), wherein the metal powder mixed in the cooling water is adsorbed to the magnetic (7), the coolant from which the metal powder is removed is separated After passing through the filtration member 8 through the through-hole (4b) a plurality of perforations on the outer periphery of (4), the filtration member 8 is mixed in the cooling water Since foreign substances such as back are filtered, the cooling water flowing out of the outlet port 4a is in a clean state.

따라서 라디에이터(11)에서의 열교환작용으로 냉각된 냉각수가 냉각수 귀환라인(12)을 통하여 워터펌프(10)로 재유입될 때에는 금속분이나 주물사 등의 이물질이 완전히 제거된 청정한 냉각수화된 상태이므로 워터펌프(10)의 밀봉수단인 메탈시일이 손상되는 사례를 예방할 수 있을뿐 아니라 서모스탯(16) 내부로 이물질이 침투하는 것도 방지할 수 있게 된다.Therefore, when the coolant cooled by the heat exchange action in the radiator 11 is re-introduced into the water pump 10 through the coolant return line 12, the water pump is a clean coolant state in which foreign substances such as metal powder or foundry sand are completely removed. In addition to preventing the case where the metal seal as the sealing means of 10 is damaged, it is possible to prevent foreign matter from penetrating into the thermostat 16.

한편, 상기와 같이 냉각수 귀환통로(12)상에 장설한 냉각수 정화장치(1)의 마그네틱(7)과 여과부재(8)에 금속분이나 주물사 등의 이물질이 많이 흡착 및 여과되므로서 유출구(4a)로 유출되는 냉각수의 유출량이 적게 될 경우 즉, 유입구(2)로 유입되는 냉각수의 유입압력에 비하여 유출구(4a)로 유출되는 냉각수의 유출압력이 낮아질 경우에는 이를 압력센서(19)가 감지하고, 그 신호를 ECU(20)에 보내면 상기 ECU(20)는 압력센서(19)의 신호를 전기적인 신호로 변환시켜 절환밸브(22)를 개방작동시키게 된다. 따라서 냉각수 정화장치(1)를 통과하는 냉각수의 유출량이 적거나 또는 막히게 되면 라디에이터(11)를 경유한 냉각수는 릴리프라인(21)을 통해 워터펌프(10)로 귀환하게 되므로서 냉각수의 순환작용을 원활하게 유지할 수 있는 것이다.On the other hand, the magnetic outlet 7 and the filtering member 8 of the cooling water purifying apparatus 1 installed on the cooling water return passage 12 as described above adsorb and filter a large amount of foreign matter such as metal powder or foundry sand, and thus the outlet port 4a. When the outflow amount of the coolant flowing out to the pressure decreases, that is, when the outflow pressure of the coolant flowing to the outlet 4a is lower than the inlet pressure of the coolant flowing into the inlet (2), the pressure sensor 19 detects this, When the signal is sent to the ECU 20, the ECU 20 converts the signal of the pressure sensor 19 into an electrical signal to open the switching valve 22. Therefore, if the flow rate of the coolant passing through the coolant purification device 1 is small or blocked, the coolant passing through the radiator 11 is returned to the water pump 10 through the relief line 21 to circulate the coolant. You can keep it smooth.

상기에서 냉각수 귀환라인(12)에 장설된 냉각수 정화장치(1)의 마그네틱(7)과 여과부재(8)에 이물질을 과다하게 흡착 및 여과되어 냉각수의 유출작용이 제대로 이루어지지 않게 되므로서 ECU(20)가 릴리프라인(21)의 절환밸브(22)를 개방시키게 될 경우에는 냉각수 정화장치(1)의 마그네틱(7) 및 여과부재(8)를 청소하거나 또는 교환하여야 하므로 이를 운전자에게 경보할 수 있도록 계기판 등에 경보등을 설치하여 냉각수 정화장치의 청소시기 또는 교환시기를 알려 줄 수 있도록 하는 것이 바람직한 구성이다.The foreign matter is excessively adsorbed and filtered on the magnetic 7 and the filtration member 8 of the coolant purification device 1 installed in the coolant return line 12 so that the outflow of the coolant is not properly performed. When the valve 20 of the relief line 21 opens, the magnetic valve 7 and the filtering member 8 of the cooling water purifier 1 need to be cleaned or replaced. It is desirable to install an alarm lamp on the instrument panel so as to indicate when to clean or replace the coolant purification device.
