U(80)에 연결되어 작동이 제어되며, 라디에이터(10)의 상부와 워터 펌프(60) 사이에 위치하도록 냉각수 공급관(40)에 3방향 마그네트 밸브(70)가 연결, 설치되어 있으며, 아울러 3방향 마그네트 밸브(70)는 워터 재킷(30)의 입구부에 냉각수 배출관(140)을 연결되면서 E. C. U(80)에 연결되어 개폐제어되도록 되어 있다.In addition, a water pump 60 is connected to and installed in the cooling water supply pipe 40 to pump the cooling water from the radiator 10 to the water jacket 30 of the engine 20 through the cooling water supply pipe 40. The operation is controlled by the 60 connected to the EC U 80 having its own power supply, and the three-way magnet valve 70 in the cooling water supply pipe 40 to be located between the upper portion of the radiator 10 and the water pump 60. Is connected and installed, and the three-way magnet valve 70 is connected to the EC U 80 while the cooling water discharge pipe 140 is connected to the inlet of the water jacket 30 is to be opened and closed control.

상기 워터 펌프(60) 및 워터 재킷(30) 사이에 위치되도록 냉각수 공급관(40)에 3방향 마그네트 밸브(90)가 연결, 설치되어 있고, 냉각수 복귀관(50)에 2방향 밸브(100)가 연결, 설치되면서 이들 3방향 마그네트 밸브(90) 및 2방향 밸브(100)가 각기 E. C. U(80)에 연결되어 개폐제어되도록 되어 있다.A three-way magnet valve 90 is connected to and installed in the cooling water supply pipe 40 so as to be located between the water pump 60 and the water jacket 30, and the two-way valve 100 is connected to the cooling water return pipe 50. These three-way magnet valves 90 and two-way valve 100 are connected to the EC U (80) to open and close while being connected and installed.

또 3방향 마그네트 밸브(90) 및 2방향 밸브(100)는 상호 냉각수 회수관(150)으로 연결되어 있다.In addition, the three-way magnet valve 90 and the two-way valve 100 is connected to the mutual coolant recovery pipe 150.

한편 워터 재킷(30)내에 자체 전원을 갖고 작동되는 수온센서(110)가 내장, 설치되면서 E. C. U(80)에 연결되어 측정온도값을 인가하도록 되어 있고, 상기 워터 펌프(60)는 정상시는 엔진에 의해 구동되고 비상시는 배터리(120)의 전원을 이용한 얼터네이터에 의해 구동되도록 구성된 것이다.Meanwhile, the water temperature sensor 110 having its own power source is installed and installed in the water jacket 30 to be connected to the EC U 80 to apply a measurement temperature value. The water pump 60 is normally It is driven by the engine and is configured to be driven by an alternator using the power of the battery 120 in an emergency.

따라서 본 발명은 도면과 같이, 엔진의 정상가동시는 라디에이터(10)로부터의 냉각수가 워터 펌프(60)의 구동에 의해 냉각수 공급관(40), 3방향 마그네트 밸브(70)(90), 워터 펌프(60), 3방향 마그네트 밸브(90)를 통해 엔진(20)의 워터 재킷(30)으로 압송되어 실린더로부터 발생된 열을 흡수, 냉각시키며, 열을 흡수한 냉각수는 워터 재킷(30)의 출구부와 냉각수 복귀관(50) 및 2방향 밸브(100)를 통해 라디에이터(10)의 하부로 복귀, 순환된다.Therefore, the present invention, as shown in the drawing, the coolant from the radiator 10 during the normal operation of the engine is driven by the water pump 60, the cooling water supply pipe 40, three-way magnet valve 70, 90, water pump ( 60) is pumped to the water jacket 30 of the engine 20 through the three-way magnet valve 90 to absorb and cool the heat generated from the cylinder, the heat absorbed cooling water is the outlet of the water jacket 30 And return to the lower portion of the radiator 10 through the coolant return pipe 50 and the two-way valve 100, and circulated.

여기서 수온센서(110)는 워터 재킷(30)내의 냉각수 온도를 상시 감지하여 E. C. U(80)로 감지된 신호를 인가하며, E. C. U(80)는 냉각수의 온도를 기준값에 비교하여 그 온도가 기준값(약5℃) 이하로 떨어질 경우 워터 재킷(30)내의 냉각수를 라디에이터(10)로 드레인시킨다.Here, the water temperature sensor 110 constantly detects the coolant temperature in the water jacket 30 and applies a signal detected by the EC U 80, and the EC U 80 compares the temperature of the coolant with a reference value and the temperature is a reference value. When the temperature falls below about 5 ° C, the cooling water in the water jacket 30 is drained to the radiator 10.

즉, 동절기에 냉각수의 온도가 기준값 이하로 계속 떨어질 경우 E. C. U(80)는 자체 전원을 이용하여 3방향 마그네트 밸브(70)(90)의 라디에이터(10)측 통로와 3방향 마그네트 밸브(90)의 워터 재킷(30) 측 통로를 폐쇄시키며, 또한 2방향 밸브(100)의 워터 재킷(30)측 통로를 폐쇄시킨다.That is, in the winter, when the temperature of the cooling water continues to fall below the reference value, the EC U 80 uses its own power source to pass through the radiator 10 side passage and the three-way magnet valve 90 of the three-way magnet valves 70 and 90. The water jacket 30 side passage of the water valve 30 is closed, and the water jacket 30 side passage of the two-way valve 100 is closed.

이들 3방향 마그네트 밸브(70)(90) 및 2방향 밸브(100)의 방향제어가 이루어짐과 동시에 E. C. U(80)는 또한 배터리(120)의 전원을 이용하여 얼터네이터를 구동시켜 워터 펌프(60)를 작동시키며, 따라서 워터 재킷(30)내의 잔류 냉각수는 냉각수 배출관(140), 3방향 마그네트 밸브(70), 워터 펌프(60), 3방향 마그네트 밸브(90), 냉각수 회수관(150), 2방향 밸브(100), 냉각수 복귀관(50)을 통해 라디에이터(10)의 하부로 드레인된다.At the same time as the direction control of these three-way magnet valves 70 and 90 and the two-way valve 100 is performed, the EC U 80 also drives the alternator using the power of the battery 120 to drive the water pump 60. Thus, the remaining coolant in the water jacket 30 is cooled water discharge pipe 140, three-way magnet valve 70, water pump 60, three-way magnet valve 90, coolant recovery pipe 150, 2 It is drained to the lower part of the radiator 10 through the directional valve 100 and the coolant return pipe 50.

워터 재킷(30)내의 냉각수가 라디에이터(10)로 완전히 배출되면 E. C. U(80)는 얼터네이터의 구동을 정지시키며, 이처럼 워터 재킷(30)내의 냉각수를 배출시킴으로써 동절기 엔진의 결빙에 의한 동파를 효율적으로 방지한다.When the coolant in the water jacket 30 is completely discharged to the radiator 10, the EC U 80 stops the operation of the alternator. Thus, by discharging the coolant in the water jacket 30, the freezing wave caused by freezing of the winter engine is efficiently prevent.

상기에서 냉각수를 부동액으로 사용할 경우에는 동파방지장치를 가동시키지 아니하여도 무방하다. 한편 엔진(20)이 재가동되어 일정온도로 되면 E. C. U(80)는 3방향 마그네트 밸브(70)의 냉각수 배출관(140)측 통로와 3방향 마그네트 밸브(90)의 냉각수 회수관(150)측 통로를 폐쇄시키며, 또한 2방향 밸브(100)의 냉각수 회수관(150)측 통로를 각기 폐쇄시켜 냉각수 순환계통을 정상적으로 회복시킨다.In the case where the cooling water is used as an antifreeze, the freeze protection device may not be operated. On the other hand, when the engine 20 is restarted and reaches a predetermined temperature, the EC U 80 passes through the cooling water discharge pipe 140 side of the three-way magnet valve 70 and the cooling water recovery pipe 150 side of the three-way magnet valve 90. And close the cooling water recovery pipe 150 side passages of the two-way valve 100 to restore the cooling water circulation system normally.

이상과 같이 본 발명은, 워터 펌프의 전, 후에 위치되도록 냉각수 공급관에 3방향 마그네트 밸브를 각기 설치하고, 냉각수 복귀관에 2방향 밸브를 설치하며, 또한 워터 펌프의 후방측 3방향 마그네트 밸브와 2방향 밸브를 냉각수 회수관으로 연결하고 워터 펌프의 전방측 3방향 마그네트 밸브를 워터 재킷에 냉각수 배출관으로 연결하고, 또한 워터 재킷내에 수온센서를 설치하여 동절기에 냉각수의 온도가 일정값 이하로 떨어질 경우 E. C. U에 의해 각 3방향 마그네트 밸브 및 2방향 밸브를 개폐, 제어시켜 냉각수 배출관 및 냉각수 회수관을 통해 워터 재킷내의 잔류 냉각수를 라디에이터로 회수시킴으로써, 다음의 엔진 재가동시 결빙에 의한 동파를 효율적으로 방지하는 효과를 갖는다.As described above, the present invention is provided with three-way magnet valves respectively in the cooling water supply pipe so as to be positioned before and after the water pump, and two-way valves are installed in the cooling water return pipe, and the three-way magnet valve and two rear side of the water pump are provided.
