Description
본 발명은 차량의 냉각 장치에 관한 것으로, 특히 냉각수를 순환시키는 워터 펌프를 전자제어식 클러치화하여 엔진의 냉간시동시에는 냉각수의 불필요한 순환을 방지함으로써 신속하게 엔진을 워밍업 하도록 하는 차량의 엔진 냉각 장치 및 방법에 관한 것이다.The present invention relates to a cooling device for a vehicle, and more particularly, to an engine-controlled cooling system for quickly cooling an engine by preventing an unnecessary circulation of the cooling water during the cold start of an engine by converting a water pump for circulating cooling water into an electronically controlled clutch; It is about a method.
일반적으로 차량의 냉각 장치는 모든 주행조건과 전속도 범위에 걸쳐서 기관이 정상 작동 온도를 유지하도록 하며, 시동초기에 엔진이 냉각되어 있을 때는 신속히 엔진이 정상작동온도에 이르도록 하는 장치로서, 이러한, 차량의 냉각장치는 첨부된 도면 도 1에 도시한 바와 같이, 엔진(1)에는 실린더 블록(2)과 실린더 헤더(3)에 설치된 냉각수 통로로 실린더 벽, 밸브시이트 밸브 가이드 연소실등과 접촉되어 연소시에 발생된 고온을 적정온도로 낮추어 정상기능을 할 수 있도록 하는 워터재킷(4)과, 난방 및 서리제거를 위한 히터코어(5)와, 해당 워터재킷(4)과 히터코어(5)에 냉각수를 압송순환 시키는 기능을 하며 밸트에 의해 강제 구동되는 워터 펌프(6)와, 온도가 높은 냉각수의 열을 외기에 전달하여 냉각하는 라디에이터(7)와, 해당 라디에이터(7)의 후방에 설치하고, 강제 통풍을 시켜 정차 및 저속 주행에도 충분한 냉각 효과를 얻는 냉각팬(8)과, 냉각수 온도에 따라 자동적으로 라이에이터(7)와 연결된 냉각수의 순환통로를 개폐하여 냉각수의 온도를 알맞게 조절하는 써모스텟(9)를 구비하여 이루어진다.In general, the vehicle's cooling system allows the engine to maintain the normal operating temperature over all driving conditions and the full speed range, and the engine to reach the normal operating temperature quickly when the engine is cooled at the beginning of the start-up. As shown in FIG. 1 of the accompanying drawings, the cooling device of the vehicle is a combustion water passage installed in the cylinder block 2 and the cylinder header 3 in the engine 1 in contact with the cylinder wall, the valve seat valve guide combustion chamber, and the like. The water jacket (4) for lowering the high temperature generated at the time to a proper temperature to perform a normal function, the heater core (5) for heating and defrosting, the water jacket (4) and the heater core (5) The water pump 6, which functions to circulate the cooling water and is forcibly driven by the belt, and the radiator 7 which transfers and cools the heat of the high temperature cooling water to the outside, and after the radiator 7, And a cooling fan (8) for forced air ventilation to obtain a sufficient cooling effect even when the vehicle is stopped and running at a low speed, and automatically opens and closes a circulation passage of the cooling water connected to the writer (7) in accordance with the cooling water temperature. The thermostat 9 which adjusts is provided.
전술한 바와 같이 구성되는 종래 차량의 냉각장치의 동작을 설명하면 다음과 같다.Referring to the operation of the conventional cooling device of the vehicle configured as described above are as follows.
먼저, 엔진(1)의 냉간시동시에는 엔진내의 냉각수가 저온을 유지하고 있게 된다. 이때에는 냉각수의 온도가 써모스탯(9)의 정상작동온도인 약87℃에 도달하지 않았으므로 써모스탯(9)이 닫히게 되어 냉각수는 라디에이터(7)를 경유하지 않고 엔진(1)의 내부에서만 순환하게 된다. 즉, 엔진(1)의 시동이후 냉각수의 온도가 약 87℃에 도달하지 않은 상태에서는 엔진(1)의 구동축과 타이밍밸트(12)에 의해 연결된 워터펌프(6)가 동작하여 냉각수는 제1호스(10)를 통해 엔진(1)의 내부에서만 순환하면서 수온이 상승하게 된다. 또한 냉각수중의 일부는 히터코어(5)의 열 교환기를 거쳐서 순환하게 된다.First, when the engine 1 is cold started, the coolant in the engine is kept at a low temperature. At this time, since the temperature of the coolant did not reach the normal operating temperature of the thermostat 9, about 87 ° C, the thermostat 9 was closed and the coolant circulated only inside the engine 1 without passing through the radiator 7. Done. That is, after the start of the engine 1, when the temperature of the coolant does not reach about 87 ° C, the water pump 6 connected by the drive shaft of the engine 1 by the timing belt 12 operates and the coolant is the first hose. The water temperature rises while circulating only inside the engine 1 through the 10. Part of the cooling water is also circulated through the heat exchanger of the heater core 5.
이후에, 엔진(1)이 시동된 후 일정한 시간이 경과하여 냉각수의 온도가 써모스탯(9)의 작동온도인 약 87℃를 넘어가면 써모스탯(9)이 열리게 되고, 이에 따라 가열된 냉각수는 타이밍밸트(12)로 엔진(1)의 구동축과 연결된 워터펌프(6)의 동작에 의해 엔진본체외에 라디에이터(7)를 경유하여 냉각된 다음 제2호스(11)를 통해 엔진(1) 내부로 재유입되어 워터재킷(4)과 히터코어(5)를 재 순환하는 동작을 반복한다.Thereafter, after a predetermined time has elapsed since the engine 1 is started, the thermostat 9 is opened when the temperature of the coolant exceeds about 87 ° C., which is the operating temperature of the thermostat 9, and thus the heated coolant is By the timing belt 12, the water pump 6 connected to the drive shaft of the engine 1 is cooled by the radiator 7 in addition to the engine body, and then into the engine 1 through the second hose 11. After reflowing, the operation of recirculating the water jacket 4 and the heater core 5 is repeated.
이와 같이, 종래에는 엔진이 회전하는 동안에는 워터펌프도 함께 회전하므로, 냉간시동의 초기상황에서도 냉각수는 워터펌프의 작동에 의해서 불필요하게 워터재킷과 히터코어를 순환하게 되므로 순환과정에서 열손실이 발생하여 신속한 엔진의 웜엄이 용이하지 않고, 촉매컨버터의 정상작동온도에 도달하는 시간이 지연되어 유해한 배기가스를 그대로 배출함과 동시에 연비가 저하되는 문제점이 있다.As such, in the related art, since the water pump is also rotated while the engine is rotating, even in the initial situation of cold start, the coolant circulates the water jacket and the heater core unnecessarily by the operation of the water pump, causing heat loss in the circulation process. There is a problem in that the engine worm is not easy, and the time to reach the normal operating temperature of the catalytic converter is delayed to discharge harmful exhaust gas as it is and at the same time, fuel economy is lowered.
본 발명은 전술한 바와 같은 문제점을 감안하여 안출한 것으로, 워터펌프를 전자클러치화하여 차량의 시동시 엔진냉각수의 온도에 따라 워터펌프를 엔진의 구동력과 접/단속함으로써 냉간시동시에는 냉각수가 순환되지 않도록 하여, 신속한 엔진의 웜엄이 가능하고, 촉매컨버터의 정상작동온도에 도달하는 시간을 단축하여 유해 배기가스를 감소시킴과 동시에 연비를 향상시킬 수 있는 차량의 엔진 냉각 장치 및 방법을 제공하는 데, 그 목적이 있다.The present invention has been made in view of the above-mentioned problems, and the water pump is electronically clutched so that the coolant circulates during cold start by contacting / interlocking the water pump with the driving force of the engine according to the temperature of the engine coolant when the vehicle is started. It is possible to provide an engine cooling apparatus and method for a vehicle that enables rapid engine warmth and shortens the time to reach the normal operating temperature of the catalytic converter, thereby reducing harmful emissions and improving fuel economy. , Its purpose is.

본 발명에 따른 차량의 엔진 냉각 장치는 첨부된 도면 도 2에 도시된 바와 같이, 엔진냉각수온도검출센서(100)와, ECM(Electronic Control Module;110)과, 워터 펌프 클러치 릴레이(120)와, 워터펌프 클러치(130)를 구비하여 이루어진다.As shown in FIG. 2, an engine cooling apparatus for a vehicle according to the present invention includes an engine coolant temperature detection sensor 100, an electronic control module (ECM) 110, a water pump clutch relay 120, It is provided with a water pump clutch (130).
상기 엔진냉각수 온도검출센서(100)는 엔진냉각수의 온도를 검출하여 해당 온도검출신호를 ECM(110)측으로 출력한다.The engine coolant temperature detection sensor 100 detects the temperature of the engine coolant and outputs a corresponding temperature detection signal to the ECM 110.
상기 ECM(110)은 상기 엔진냉각수 온도검출센서(100)로 부터 온도검출신호를 인가받아 엔진 냉각수의 온도를 산출한 후, 이에 대응하는 단속 제어신호를 워터 펌프 클러치 릴레이(120)측으로 출력한다.The ECM 110 receives the temperature detection signal from the engine coolant temperature detection sensor 100, calculates the temperature of the engine coolant, and outputs an intermittent control signal corresponding to the water pump clutch relay 120.
상기 워터 펌프 클러치 릴레이(120)는 상기 ECM(110)으로부터 인가되는 단속 제어신호에 따라 접점 온/오프 동작한다.The water pump clutch relay 120 operates contact on / off according to an intermittent control signal applied from the ECM 110.
상기 워터 펌프 클러치(130)는 일측(130a)에는 엔진 구동 타이밍 벨트(12)와 연결되고 다른일측(130b)에는 워터펌프(6)와 연결되어 상기 워터 펌프 클러치 릴레이(120)의 동작에 의해 인가되는 전류에 따라 상기 엔진 구동 타이밍 벨트(12)와 워터 펌프(6)의 결합을 단속하여 냉각수의 흐름을 제어한다.The water pump clutch 130 is connected to the engine driving timing belt 12 on one side 130a and connected to the water pump 6 on the other side 130b and applied by the operation of the water pump clutch relay 120. The flow of the coolant is controlled by intermittently coupling the engine driving timing belt 12 and the water pump 6 according to the current.
전술한 바와 같이 구성되는 본 발명의 동작을 첨부된 도면 도1 내지 도2의 구성블록도 및 도3의 동작순서도에 따라 상세하게 설명하면 다음과 같다.The operation of the present invention configured as described above will be described in detail with reference to the block diagrams of FIGS. 1 to 2 and the operation flowchart of FIG. 3 as follows.
본 발명의 실시예에 따라 첨부된 도면 도 2에 도시된 바와 같이, 워터펌프클러치(130)는 일측(130a)에는 엔진 구동 타이밍 벨트(12)와 연결되고 다른일측(130b)에는 워터펌프(6)와 연결되어 상기 워터 펌프 클러치 릴레이(120)의 동작에 의해 인가되는 전류에 따라 상기 엔진 구동 타이밍 벨트(12)와 워터 펌프(6)의 결합을 단속하게 되며, 해당 워터펌프클러치(130)는 전기적인 제어신호에 의해 용이하게 동작해야 하므로 전자석의 원리를 이용한 마그네틱 클러치를 사용하는 것이 바람직하다.2, the water pump clutch 130 is connected to an engine driving timing belt 12 on one side 130a and a water pump 6 on the other side 130b. And coupled to the engine driving timing belt 12 and the water pump 6 according to the current applied by the operation of the water pump clutch relay 120, the corresponding water pump clutch 130 is Since it must be easily operated by the electric control signal, it is preferable to use a magnetic clutch using the principle of the electromagnet.
먼저, 엔진이 동작되면(스텝 S1), ECM(110)은 엔진냉각수 온도검출센서(100)로 부터 온도검출신호를 인가받아 현재 냉각수의 온도를 산출하여 이를 기설정된 온도와 비교한다(스텝 S2). 이때 본 발명의 실시예에 따라 기설정된 온도는 써모스탯(9)이 열리기 전의 온도인 약 80℃로 설정되어 있다. 따라서, 초기의 냉간시동시에는 냉각수의 온도가 80℃보다는 낮을 것이므로 ECM(110)은 워터 펌프 클러치 릴레이(120)를 오프시킨다(스텝 S3). 이에 따라, 워터펌프클러치(130)는 차단되어 엔진 구동 타이밍 벨트(12)와 연결된 일측(130a)만 냉각팬(8)과 함께 공회전하게 되고, 워터펌프(6)와 연결된 다른 일측(130b)은 구동력이 없어 회전하지 않게 되므로, 워터펌프(6)는 동작하지 않아 냉각수는 엔진의 내부, 즉, 워터재킷(4)과 히터코어(5)를 순환하지 않게되어, 순환에 따른 열손실이 발생하지 않아 신속하게 엔진이 웜엄될 수 있다.First, when the engine is operated (step S1), the ECM 110 receives the temperature detection signal from the engine coolant temperature detection sensor 100, calculates the temperature of the current coolant, and compares it with the preset temperature (step S2). . At this time, according to the embodiment of the present invention, the preset temperature is set to about 80 ° C., which is a temperature before the thermostat 9 is opened. Therefore, at the initial cold start, the temperature of the coolant will be lower than 80 ° C, so the ECM 110 turns off the water pump clutch relay 120 (step S3). Accordingly, the water pump clutch 130 is blocked so that only one side 130a connected to the engine driving timing belt 12 idles together with the cooling fan 8, and the other side 130b connected to the water pump 6 is Since there is no driving force and does not rotate, the water pump 6 does not operate so that the coolant does not circulate inside the engine, that is, the water jacket 4 and the heater core 5, so that no heat loss occurs due to circulation. The engine can be warmed quickly.
한편, 엔진이 시동된 후 일정시간이 경과하여 냉각수의 온도가 80℃를 넘게되면, 상기 스텝 S2에서 냉각수의 온도가 80℃보다는 높으므로 ECM(110)은 워터 펌프 클러치 릴레이(120)를 온시킨다(스텝 S4). 이에 따라, 워터펌프클러치(130)는 결합되어 엔진 구동 타이밍 벨트(12)와 연결된 일측(130a)과 워터펌프(6)와 연결된 또다른 일측(130b)이 엔진의 회전력에 의해 연동함으로써 워터펌프(6)는 동작하게 된다. 따라서, 일반적인 냉각수의 흐름을 형성한다. 즉, 냉각수의 온도가 써모스탯(9)의 동작온도인 약 87℃에 도달하기 전에는 냉각수는 엔진의 내부의 워터재킷(4)과 히터코어(5)를 순환하고, 냉각수의 온도가 써모스탯(9)의 동작온도인 약 87℃를 넘어가면 써모스탯(9)이 열리게 되고, 이에 따라 가열된 냉각수는 엔진본체외에 라디에이터(7)를 경유하여 냉각된 다음 엔진(1) 내부로 재유입되어 워터재킷(4)과 히터코어(5)를 재 순환하는 동작을 반복한다.On the other hand, if the temperature of the cooling water exceeds 80 ℃ after a predetermined time after the engine is started, the ECM 110 turns on the water pump clutch relay 120 because the temperature of the cooling water is higher than 80 ℃ in step S2. (Step S4). Accordingly, the water pump clutch 130 is coupled to one side 130a connected to the engine driving timing belt 12 and another side 130b connected to the water pump 6 interlock with each other by the rotational force of the engine. 6) is activated. Thus, a general coolant flow is formed. That is, before the temperature of the coolant reaches about 87 ° C., the operating temperature of the thermostat 9, the coolant circulates through the water jacket 4 and the heater core 5 in the engine, and the temperature of the coolant When the operating temperature of 9) is exceeded about 87 ° C., the thermostat 9 is opened. Accordingly, the heated coolant is cooled by the radiator 7 outside the engine body and then re-introduced into the engine 1 to provide water. The operation of recirculating the jacket 4 and the heater core 5 is repeated.
전술한 바와 같이, 본 발명은 워터펌프를 전자클러치화하여 차량의 시동시 엔진냉각수의 온도에 따라 워터펌프를 엔진의 구동력과 접/단속함으로써 냉간시동시에는 냉각수가 순환되지 않도록 하여, 신속한 엔진의 웜엄이 가능하고, 촉매컨버터의 정상작동온도에 도달하는 시간을 단축하여 유해 배기가스를 감소시킴과 동시에 연비를 향상시킬 수 있다.As described above, the present invention is to electronically clutch the water pump to contact / interlock the water pump with the driving force of the engine according to the temperature of the engine coolant at the start of the vehicle so that the coolant is not circulated during cold start, so that Wormham is possible, and it is possible to shorten the time to reach the normal operating temperature of the catalytic converter to reduce harmful emissions and at the same time improve fuel economy.
