본 고안은 자동차의 엔진 냉각 시스템에 설치되는 물탱크에 관한 것으로 이는 특히 3개의 냉각수 격실을 갖는 물탱크에 의해 냉각수의 온도 변화에 따른 체적과 압력 변화를 효율적으로 흡수시킬 수 있도록 하여 압력평형을 가져오며, 이로 인하여 엔진 냉각의 효율을 증대시킬 수 있도록 한 자동차의 엔진 냉각용 물탱크에 관한 것이다.The present invention relates to a water tank installed in an engine cooling system of an automobile, and in particular, a water tank having three coolant compartments can efficiently absorb a volume and pressure change due to a change in temperature of the coolant, resulting in a pressure balance. In this regard, the present invention relates to a water tank for engine cooling of a vehicle that can increase the efficiency of engine cooling.

일반적으로 알려져 있는 자동차의 냉각 시스템은, 냉각수가 들어 있는 물탱크가 자동차 엔진과 엔진 벤트 호스로 연설되어 냉각토록 하며, 상기 엔진 냉각수는 차량의 운행 조건 등에 따라 온도변화가 발생되어 상기 냉각수의 온도변화에 의해 냉각수의 체적 및 압력변화가 발생하게 된다.BACKGROUND ART In general, a cooling system of a vehicle includes a water tank containing coolant, which is delivered to an automobile engine and an engine vent hose to cool the engine, and the engine coolant changes in temperature depending on a driving condition of the vehicle, thereby changing the temperature of the coolant. This causes a change in the volume and pressure of the coolant.

한편, 상기와 같은 엔진 냉각용 냉각수가 유입되는 종래의 물탱크에 있어서는, 상각형 형상의 단일 격실이 형성되어 상기 격실 상측에 캡을 설치하고 하측에는 냉각수 공급호스를 연결하여 순환작용에 의해 엔진을 냉각시키도록 하는 구조로 이루어진다.On the other hand, in the conventional water tank in which the coolant for engine cooling flows as described above, a single compartment having an angled shape is formed, a cap is installed on the upper side of the compartment, and a cooling water supply hose is connected to the lower side to circulate the engine. It is made of a structure to cool.

상기와 같은 구조를 갖는 종래의 물탱크는, 냉각수의 온도변화에 따른 냉각수 체적 및 압력의 변화를 효과적으로 흡수할 수 없는 단순한 사각형 하우징 형태로 구성되어 엔진에 공급되는 냉각수가 최적의 조건을 유지하지 못하게 되며, 이로인한 냉각효율의 저하 및 엔진의 과부하 발생 등의 단점이 있는 것이다.The conventional water tank having the structure as described above has a simple rectangular housing type that cannot effectively absorb the change in the coolant volume and the pressure caused by the temperature change of the coolant so that the coolant supplied to the engine does not maintain optimal conditions. This is because of the disadvantages such as lowering of the cooling efficiency and the overload of the engine.

또한, 상기 냉각수가 유입되는 물탱크는, 그 내부의 압력 발생시 이를 손쉽게 제거하지 못하고, 손으로 직접 물탱크 상측의 캡을 돌려주어 개폐시켜야 하는 관계로, 높은 온도로 가열된 냉각수의 유출을 초래하게 되며, 정비자가 화상을 입게되는 경우가 빈번하게 발생되는 문제점이 있었던 것이다.In addition, the water tank into which the coolant flows is not easily removed when the internal pressure is generated, and the cap of the upper portion of the water tank needs to be directly opened and closed by hand, thereby causing the outflow of the coolant heated to a high temperature. And, there is a problem that often occurs when the maintenance worker is burned.

본 고안은 이와 같은 종래의 여러 문제점들을 개선시키기 위하여 안출된 것으로서 그 목적은, 3개의 냉각수 격실을 갖는 3중구조의 물탱크에 의하여 냉각수의 온도변화에 의한 냉각수 체적변화와 압력 변화를 상기 물탱크 자체로서 효율적으로 흡수 시킬 수 있게 되며, 최적 상태의 냉각수를 엔진에 공급하게 되어 엔진 냉각의 효율을 극대화 할 수 있게하여 엔진의 과부하를 방지하고, 고온고압의 냉각수가 정비자등에게 직접 유출되는 것을 방지하여 이로 인한 정비자의 부상을 예방할 수 있도록 한 자동차의 엔진 냉각용 물탱크를 제공하는데 있다.The present invention has been made to improve the various problems of the related art, and its purpose is to provide a coolant volume change and a pressure change caused by a temperature change of the coolant by a triple water tank having three coolant compartments. It can be absorbed efficiently and supply the coolant of optimum state to the engine to maximize the efficiency of engine cooling to prevent the overload of the engine and to prevent the high temperature and high pressure coolant from leaking directly to the maintenance workers. Therefore, to provide a water tank for cooling the engine of the car to prevent the injury of the operator due to this.

The second and third coolant compartments 6 and 7 are respectively provided on both sides of the first coolant compartment 4 in which the first coolant compartment 4 is provided via the diaphragm 5, and the diaphragm of the bottom of the second coolant compartment 6. In (5), a plurality of cooling water inlet holes (8) are laid down, and an overflow pipe (10) is installed below the pressure cap (9) provided on the upper side and is extended to the third cooling water deletion (7), and the pressure on the upper one side A removal drain pipe 12 is formed, and a pressure cap 9 'having a vent pipe 11 connected thereto is installed above the third cooling water compartment 7.

또한, 상기 제2냉각수 격실(6)의 상부 일측벽면에 설치된 드레인관(12)은, 그 내부에 드레인 플러그(13)가 상하이동가능하게 설치되며, 드레인관(12)의 중앙상부에는 압력배출구(14)가 형성되는 구성으로 이루어진다.In addition, the drain pipe 12 installed on the upper one side wall surface of the second cooling water compartment 6 has a drain plug 13 installed therein so as to be movable, and a pressure discharge port in the upper center of the drain pipe 12. (14) is formed.

이와같은 구조로 구성된 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention composed of such a structure as follows.

제1도 내지 제3도에 도시한 바와같이, 물탱크(1)의 저부에 형성된 제1냉각수 격실(4)의 일측 벽면에 냉각수 주입구(3)가 마련되어 제1냉각수 격실(4) 내부로 냉각수(2)가 냉각수 주입구(3)의 높이만큼 유입토록 한다.As shown in FIGS. 1 to 3, a coolant inlet 3 is provided on one side wall of the first coolant compartment 4 formed at the bottom of the water tank 1 to cool the coolant into the first coolant compartment 4. (2) is to be introduced by the height of the cooling water inlet (3).

또한, 상기 제1냉각수 격실(4)의 상측으로는 격판(5)을 개재하여 제2 및 제3냉각수 격실(6)(7)이 각각 설치되며, 상기 제1냉각수 격실(4)에 적재되는 냉각수(2)의 온도변화에 의해 체적 및 압력이 증가되는 경우, 상기 냉각수(2)는 압력차의 교환이 용이하게 격판(5)에 다수개 천설되는 냉각수 유입홀(8)을 통해 제2냉각수 격실(6)로 유입토록 되며, 상기 냉각수 유입홀(8)에 의해 냉각수 압력차에 의한 교환이 이루어져 물탱크(1)내의 압력이 저하됨으로써 제1냉각수 격실(4)내의 압력평형이 형성된다.In addition, the second and third coolant compartments 6 and 7 are respectively installed on the upper side of the first coolant compartment 4 via the diaphragm 5, and are mounted in the first coolant compartment 4. When the volume and the pressure increase due to the temperature change of the coolant 2, the coolant 2 is the second coolant through the coolant inlet hole 8 which is laid in the diaphragm 5 to facilitate the exchange of the pressure difference. It is to be introduced into the compartment (6), by the cooling water inlet hole (8) is exchanged by the coolant pressure difference, the pressure in the water tank (1) is lowered, thereby forming a pressure balance in the first cooling water compartment (4).

한편, 상기 제2냉각수 격실(6)의 압력이 과대하게 형성되면, 그 상측의 압력캡(9)이 개방되어 상기 압력캡(9)의 하측으로 연설된 오버 플로어관(10)을 따라 증기 및 냉각수가 제3냉각수 격실(7)로 유입되고, 상기 제3냉각수 격실(7)의 상측에 형성되는 압력캡(9')은 제2냉각수 격실(6)에 착설되는 압력캡(9) 보다 고압에서 작동토록 설치되어 압력캡(9)(9')의 동시 개방시 발생하는 냉각수의 유실을 방지하며, 상기 제3냉각수 격실(7)에 유입된 냉각수의 압력이 계속해서 증가되는 경우에는 그 상측의 압력 캡(9')이 개방토록 되어, 대기상으로 압력을 해제시키게 된다.On the other hand, if the pressure of the second coolant compartment 6 is excessively formed, the upper pressure cap 9 is opened to open the steam and along the overflow pipe 10 extending downward to the pressure cap 9. Cooling water flows into the third coolant compartment 7, and the pressure cap 9 ′ formed above the third coolant compartment 7 has a higher pressure than the pressure cap 9 installed in the second coolant compartment 6. It is installed so as to operate in the to prevent the loss of the cooling water generated when the pressure cap (9) (9 ') at the same time opening, the upper side of the cooling water flowing into the third coolant compartment (7) if the pressure is continuously increased The pressure cap 9 'is opened to release the pressure to the atmospheric phase.

또한, 차량의 작동이 중지되거나, 작동조건이 완화되어 내부의 압력이 저하되면, 제3냉각수 격실(7)로 유출되었던 냉각수가 부압에 의해 제2냉각수 격실(6)로 재유입하게 되는 것이다.In addition, when the operation of the vehicle is stopped or the operating conditions are alleviated to decrease the internal pressure, the coolant that has flowed into the third coolant compartment 7 is reintroduced into the second coolant compartment 6 by the negative pressure.

한편, 차량의 운행 상황하에서는 내부의 압력이 형성되어 있는 상태에서 냉각수 주입구(3)를 개방시킬 경우 압력 분출로 인한 화상의 위험성이 존재하게 되므로, 이때 먼저 제2냉각수 격실(6)의 드레인 플러그(13)를 풀어주게 되면, 상측으로 형성토록 되고 압력 배출구(14)를 통해 압력이 배출되어 냉각수 주입구(3)를 개방하더라도 탱크(1)내의 압력증가 상태에서 고온의 압력 분출로 인한 화상 발생을 미연에 예방토록 한다.On the other hand, under the driving situation of the vehicle, when opening the coolant inlet 3 while the internal pressure is formed, there is a risk of burns due to the pressure jet. Therefore, the drain plug of the second coolant compartment 6 is first used. 13) is released, it is formed to the upper side and the pressure is discharged through the pressure outlet 14 to open the cooling water inlet (3), even if the pressure increase in the tank (1) does not cause burns due to the high temperature pressure ejection To prevent.

이에 따라서, 엔진을 냉각하는 냉각수(2)는, 제2냉각수 격실(4) 및 제2, 제3냉각수 격실(6)(7)을 통하여 최적의 상태로 유지되면서 엔진에 유입토록 되는 것이다.Accordingly, the coolant 2 for cooling the engine is allowed to flow into the engine while maintaining the optimum state through the second coolant compartment 4 and the second and third coolant compartments 6 and 7.

이상과 같이 본 고안에 따른 자동차의 엔진 냉각용 물탱크에 의하면, 3개의 냉각수 격실을 갖는 물탱크에 의하여 냉각수의 온도 변화에 의한 냉각수 체적 변화와 압력변화를 효과적으로 흡수시킬 수 있게 되며, 이에 따라 최적 상태의 냉각수를 엔진에 공급하게 되어 엔진의 냉각 효율을 극대화시킬 수 있게 하여 엔진의 과부하를 방지하고, 고온고압의 냉국수의 직접유출로 인한 정비자의 부상을 미연에 방지하는 등의 우수한 효과가 있다.As described above, according to the water tank for engine cooling of an automobile according to the present invention, the water tank having three coolant compartments can effectively absorb the change in the coolant volume and the pressure change due to the temperature change of the coolant, and thus the optimum It is possible to maximize the cooling efficiency of the engine by supplying the coolant in the state to prevent the overload of the engine, and to prevent the injury of the operator due to the direct outflow of cold high-pressure cold water of the hot water in advance.
