Description

서머스탯의 에어 배출 구조Air exhaust structure of thermostat

본 발명은 엔진의 수냉식 냉각 장치에 구비되는 서머스탯의 에어 배출 구조에 관한 것으로서, 특히 서머스탯 하우징에 셔터형 개폐구를 설치함으로써 서머스탯 내부에 공기가 포집될 경우 개방되고 라디에이터측의 냉각수 역류시에는 닫히게 되어 공기 배출 효과가 상승됨은 물론 엔진의 과열이 방지되어 냉각 성능이 향상되도록 한 서머스탯의 에어 배출 구조에 관한 것이다.The present invention relates to an air discharge structure of the thermostat provided in the water-cooled cooling device of the engine, and in particular, by installing a shutter-type opening and closing in the thermostat housing, the air is opened when the air is collected inside the thermostat. It is related to the air discharge structure of the thermostat which is closed to increase the air discharge effect and to prevent the overheating of the engine to improve the cooling performance.

엔진의 수냉식 냉각장치는 도 1에 도시된 바와 같이 워터 펌프(1)에 의해 냉각수를 실린더 블럭(3) 및 실린더 헤드(2)에 워터 재킷(4)으로 냉각수를 라디에이터(5)로 끌어들여 방열하며 데워진 물은 또다시 워터 펌프(1)를 이용해 순환시키고 있다. 또한 워터 펌프(1)에는 팬(6)이 설치되어 있어서 강제적으로 라디에이터(5)로 보내 외기를 접촉시켜 방열 효과를 좋게 한다. 또한 워터 재킷(4)과 라디에이터(5) 사이에는 서머스탯이(7) 설치되어 있어서 온도에 따라 냉각수의 순환경로를 변환하게 되어 있다.As shown in FIG. 1, the water-cooled cooling device of the engine draws the coolant to the radiator 5 by drawing the coolant to the cylinder block 3 and the cylinder head 2 to the water jacket 4 by the water pump 1. The heated water is circulated again using the water pump (1). In addition, the water pump 1 is provided with a fan 6 forcibly sent to the radiator 5 to contact the outside air to improve the heat dissipation effect. In addition, a thermostat 7 is provided between the water jacket 4 and the radiator 5 so as to change the circulation path of the cooling water according to the temperature.

여기서, 서머스탯은 도 2에 도시된 바와 같이 서머스탯 하우징(11)에 설치한 스핀들(12)과 펠릿(13)에 설치한 밸브(14) 및 스프링(15)을 결합한 것으로 펠릿(13) 안에는 왁스(16)와 함께 고무재(17)가 봉입되어 있다. 이 왁스(16)의 팽창 및 수축을 이용하여 밸브(14)를 개폐하게 된다.Here, the thermostat is a combination of the spindle 12 installed in the thermostat housing 11 and the valve 14 and the spring 15 installed in the pellet 13, as shown in Figure 2 in the pellet 13 The rubber material 17 is enclosed with the wax 16. The expansion and contraction of the wax 16 is used to open and close the valve 14.

즉, 냉각수의 온도가 낮을 때에는 도 2의 상태와 같이 밸브(14)가 닫혀있게 된다. 이와 같은 상태에서 냉각수가 규정 온도까지 높아지면 펠릿(13) 안의 왁스(16)가 팽창하여 고무재(17)를 압축함으로써 그 중심부에 있는 스핀들(12)을 밀어 올리려고 하나 스핀들(12)은 서머스탯 하우징(11)에 고정되어 있으므로 펠릿(13)이 밀려 내려가서 밸브(14)가 열리게 된다. 반대로 냉각수의 온도가 낮아지면 팽창했던 왁스(16)가 수축되고 고무재(17)의 압축이 제거되어 펠릿(16)은 스프링(15)에 의해 원위치로 돌아가면서 밸브(14)는 닫힌다.That is, when the temperature of the cooling water is low, the valve 14 is closed as in the state of FIG. 2. In this state, when the coolant reaches a prescribed temperature, the wax 16 in the pellet 13 expands to compress the rubber material 17 to push up the spindle 12 at its center, but the spindle 12 Since it is fixed to the stat housing 11, the pellet 13 is pushed down and the valve 14 is opened. On the contrary, when the temperature of the cooling water is lowered, the expanded wax 16 shrinks and the compression of the rubber material 17 is removed, so that the pellet 16 is returned to its original position by the spring 15 and the valve 14 is closed.

특히, 상기 서머스탯 하우징(11)에는 냉각수의 온도가 일정 온도 이하인 상태에서 밸브(14)가 닫혀있을 때, 엔진의 냉각수 통로상에서 포집된 공기를 라디에이터측으로 배출할 수 있도록 에어 배출 밸브(20)가 설치되어 있다.Particularly, in the thermostat housing 11, when the valve 14 is closed while the temperature of the coolant is lower than a predetermined temperature, the air discharge valve 20 may discharge air collected on the coolant passage of the engine to the radiator side. It is installed.

상기한 에어 배출 밸브(20)는 서머스탯 하우징(7)에 형성된 에어 배출구(11a)의 내외측으로 설치되는데, 외측에는 일정 무게를 갖는 원통형의 매스부(22)가 위치되고, 내측에는 상기 매스부(22)와 에어 배출구(11a)를 통해 연결되어 내부 공기의 저항에 의해 회동되도록 판형의 작용부(24)가 위치되어 있다.The air discharge valve 20 is installed to the inside and outside of the air outlet (11a) formed in the thermostat housing (7), the cylindrical mass portion 22 having a predetermined weight is located on the outside, the mass portion inside The plate-shaped acting portion 24 is positioned so as to be connected via the air outlet 11a and rotated by the resistance of the internal air.

상기와 같은 종래 서머스탯의 에어 배출 구조는 엔진의 냉각수속에 공기가 차게 되면 서머스탯 내부에 어느 정도 포집되었다가 상기 에어 배출 밸브(20)의 작용부(24)를 밀게되면서 외측의 매스부(22)를 회동시켜 에어 배출구(11a)를 개방시키게 된다. 이때 엔진의 냉각수 통로측에 포집된 공기가 라디에이터 방향으로 빠져나가게 된다.The air discharge structure of the conventional thermostat as described above is trapped to some extent inside the thermostat when the air is filled in the cooling water of the engine, and pushes the action part 24 of the air discharge valve 20 to the outer mass part 22. ) Is rotated to open the air outlet 11a. At this time, the air collected in the coolant passage side of the engine is discharged in the direction of the radiator.

그러나, 상기와 같이 구성되고 작동되는 종래 서머스탯의 에어 배출 구조는 서머스탯 내부에 포집된 공기가 에어 배출구(11a)를 통해 배출되기 위해서는 에어 배출 밸브(20)가 좌우 방향으로 회전되였을 때 배출되기 때문에 서머스탯의 설치가 상하 방향으로 정확히 이루어지지 않으면 공기를 배출하는 작동이 원활하게 수행되지 못하는 문제점이 있다.However, the air discharge structure of the conventional thermostat configured and operated as described above is discharged when the air discharge valve 20 is rotated in the left and right directions so that the air collected inside the thermostat is discharged through the air discharge port 11a. Since there is a problem that the operation to discharge the air is not performed smoothly if the installation of the thermostat is not made exactly in the vertical direction.

즉, 현재 자동차의 냉각 장치를 배치하는 있어서 서머스탯(7)을 상하 방향으로만 설치하지 않고, 일정 기울게 설치하거나 옆방향으로 설치하는 경우가 있기 때문에 이때에는 에어 배출 밸브가 제대로 작동할 수 없게 된다.That is, in the present arrangement of the cooling device of the vehicle, the thermostat 7 may not be installed only in the vertical direction, but may be installed at a certain inclination or in the lateral direction. At this time, the air discharge valve may not operate properly. .

본 발명은 상기한 문제점을 해결하기 위해 안출된 것으로서, 서머스탯 하우징의 공기 배출구에 얇은 막으로 다수 중첩된 셔터형 개폐구를 설치함으로써 공기 배출 효과를 상승시켜 엔진의 과열을 방지하고 냉각 성능을 향상시킨 서머스탯의 에어 배출 구조를 제공하는 데 있다.The present invention has been made to solve the above problems, by installing a plurality of overlapping shutter-type opening and closing the air outlet of the thermostat housing in a thin film to increase the air discharge effect to prevent overheating of the engine and improve the cooling performance It is to provide an air exhaust structure of the thermostat.

이하, 첨부된 도면을 참조하여 본 발명의 실시 예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

본 발명에 의한 서머스탯의 에어 배출 구조는 도 3에 도시된 바와 같이 서머스탯(50) 내부에 포집된 공기를 라디에이터측으로 배출할 수 있도록 공기 배출구(51a)가 형성된 서머스탯 하우징(51)과, 상기 서머스탯 하우징(51)의 외측면에 설치되어 상기 공기 배출구(51a)를 개폐시키도록 얇은 막이 중첩되게 형성된 셔터형 개폐구(60)로 구성되어 있다.Air discharge structure of the thermostat according to the present invention is a thermostat housing 51 formed with an air outlet 51a to discharge the air collected in the thermostat 50 to the radiator side, as shown in Figure 3, Is installed on the outer surface of the thermostat housing 51 is composed of a shutter-type opening and closing port 60 formed so that a thin film is overlapped to open and close the air outlet (51a).

그리고, 상기 셔터형 개폐구(60)는 내부의 공기가 배출될 때는 도 4a에 도시된 바와 같이 개방되고, 라디에이터측에서 냉각수가 역류될 때는 도 4b에 도시된 바와 같이 폐쇄되도록 원뿔형으로 중첩되게 형성되고, 상기 서머스탯 하우징(51)에 회전 가능토록 힌지(65)로 연결되어 있다.In addition, the shutter-type opening and closing hole 60 is opened as shown in FIG. 4A when the air inside is discharged, and is formed to overlap in a conical shape so as to be closed as shown in FIG. 4B when the coolant flows back from the radiator side. Is connected to the thermostat housing 51 by a hinge 65 so as to be rotatable.

상기와 같이 구성되는 본 발명에 따른 서머스탯의 에어 배출 구조의 작용을 설명하면 다음과 같다.Referring to the operation of the air discharge structure of the thermostat according to the present invention configured as described above are as follows.

엔진의 냉각수가 일정 온도 이하인 조건에서는 서머스탯의 밸브(54)가 닫혀있게 된다. 이와 같은 상태에서 서머스탯(50)에 엔진의 냉각수 통로에서 발생되는 공기가 포집되면서 공기의 증기압이 일정 이상이 될 때 서머스탯 하우징(51)의 에어 배출구(51a)를 막고 있던 셔터형 개폐구(60)가 개방되게 된다.Under the condition that the coolant of the engine is below a certain temperature, the valve 54 of the thermostat is closed. In this state, when the air generated in the coolant passage of the engine is trapped in the thermostat 50 and the steam pressure of the air becomes a predetermined value, the shutter-type opening / closing opening 60 which is blocking the air outlet 51a of the thermostat housing 51. ) Will open.

즉, 상기 셔터형 개폐구(60)는 얇은 막이 다수 중첩되어 서머스탯 하우징(51)에 힌지(65)로 연결되어 있기 때문에 내부의 증기압이 높아지면 중첩되어 있다가 힌지(65)를 중심으로 펼쳐지면서 개방되고, 이때 서머스탯(50) 내부의 공기는 에어 배출구를 통해 라디에이터측으로 배출되게 된다.That is, since the shutter-type opening and closing hole 60 overlaps a plurality of thin films and is connected to the thermostat housing 51 by the hinge 65, when the internal vapor pressure increases, the shutter opening / closing 60 overlaps the hinge 65 while being unfolded around the hinge 65. When opened, the air in the thermostat 50 is discharged to the radiator side through the air outlet.

이와 같이 엔진측의 공기가 배출되면 서머스탯(50) 내부의 증기압이 떨어지게 되므로 셔터형 개폐구(60)는 다시 닫히게 된다. 또한, 서머스탯(50)을 통과한 라디에이터측의 냉각수가 서머스탯(50) 내부로 역류하려 할 때도 원뿔형으로 형성된 셔터형 개폐구(60)가 좁혀지면서 중첩되어 냉각수의 역류를 차단하게 된다.When the air on the engine side is discharged in this way, since the steam pressure inside the thermostat 50 falls, the shutter-type opening and closing hole 60 is closed again. In addition, when the coolant on the radiator side having passed through the thermostat 50 tries to flow back into the thermostat 50, the shutter-type opening and closing hole 60 formed in a conical shape is narrowed to overlap and block the backflow of the coolant.

상기와 같이 구성되고 작용하는 본 발명에 의한 서머스탯의 에어 배출 구조는 서머스탯 하우징의 공기 배출구에 얇은 막으로 다수 중첩된 셔터형 개폐구가 설치되어 있기 때문에 엔진측에 생성된 공기 배출 효과를 상승시켜 엔진의 과열을 방지하고 냉각 성능을 향상시키는 이점이 있다.The air discharge structure of the thermostat according to the present invention configured and acting as described above increases the air discharge effect generated on the engine side because a plurality of shutter-type openings and exits are installed in the air outlet of the thermostat housing in a thin film. This has the advantage of preventing overheating of the engine and improving cooling performance.
