본 발명은 차량용 냉각수 저장탱크에 관한 것으로서, 저장탱크 내에서 오버플로우되는 냉각수의 드레인 구조가 개선된 차량용 냉각수 저장탱크에 관한 것이다. The present invention relates to a vehicle cooling water storage tank, and to a vehicle cooling water storage tank having an improved drainage structure of the cooling water overflowed in the storage tank.

차량의 엔진룸 내부에는 엔진의 과열을 방지하기 위한 수냉식 냉각장치가 설치되어 있다. In the engine room of the vehicle, a water cooling device is installed to prevent overheating of the engine.

일반적인 차량의 수냉식 냉각장치(미도시)는 냉각수를 수용하며 엔진(미도시)과 냉각수 순환 가능하게 연결된 라디에이터(미도시)와, 라디에이터(미도시)의 냉각수를 순환시키는 워터펌프(미도시)와, 라디에이터(미도시)와 오버플로우관(미도시)으로 연결된 냉각수 저장탱크 등으로 구성되어 있다. A typical water-cooled cooling device (not shown) of a vehicle includes a radiator (not shown) connected with an engine (not shown) and capable of circulating coolant, and a water pump (not shown) for circulating the coolant of the radiator (not shown); The cooling water storage tank is connected to a radiator (not shown) and an overflow pipe (not shown).

이 중 냉각수 저장탱크는 도 1에 도시된 바와 같이, 냉각수를 수용하는 저장탱크(101)와, 저장탱크(101)의 저부영역에 형성되어 라디에이터(미도시)와 오버플로우관(미도시)으로 연결된 냉각수유입구(121)와, 저장탱크(101)의 상부영역 형성되어 저장탱크(101) 내에서 오버플로우되는 냉각수를 외부로 드레인 배출시키는 냉각수배출구(141) 및 드레인호스(143)와, 냉각수의 보충을 위해 저장탱크(101)의 상부면에 형성된 냉각수주입구(미도시)와, 냉각수주입구(미도시)를 개폐시키는 리저버캡(132)을 가지고 있다. Among them, as shown in FIG. 1, the cooling water storage tank is formed in a storage tank 101 for receiving cooling water and a bottom region of the storage tank 101 to a radiator (not shown) and an overflow pipe (not shown). The cooling water inlet 121 and the upper region of the storage tank 101 are connected to the cooling water inlet 141 and the drain hose 143 to drain and discharge the cooling water overflowed in the storage tank 101 to the outside. It has a cooling water inlet (not shown) formed on the upper surface of the storage tank 101 and the reservoir cap 132 for opening and closing the cooling water inlet (not shown) for replenishment.

이러한 구조를 갖는 종래 냉각수 저장탱크(101)는 라디에이터(미도시)에서의 냉각수 온도상승 및 비정상적인 압력에 의한 냉각수의 체적 증가 등의 이유로 오버플로우관(미도시)을 통해 냉각수가 저장탱크(101)로 과도하게 유입되면, 저장탱크(101)의 상부영역에 마련된 냉각수배출구(141)와 드레인호스(143)를 통해 냉각수를 외부로 드레인시킨다. In the conventional cooling water storage tank 101 having such a structure, the cooling water is stored in the storage tank 101 through an overflow pipe (not shown) due to a rise in the temperature of the cooling water in the radiator (not shown) and an increase in the volume of the cooling water due to abnormal pressure. When excessively introduced into the drain, the coolant is drained to the outside through the coolant outlet 141 and the drain hose 143 provided in the upper region of the storage tank 101.

그런데, 이러한 종래 냉각수 저장탱크(101)에 있어서는 냉각수를 외부로 드레인시키기 위해 드레인호스(143)를 별도로 마련하여 냉각수배출구(141)에 연결하여 사용하기 때문에, 부품증가 및 원가상승을 초래하는 문제점이 있었다. However, in the conventional cooling water storage tank 101, since a drain hose 143 is separately provided to be used to drain the cooling water to the outside and connected to the cooling water discharge port 141, there is a problem of increasing parts and increasing costs. there was.

이에 따라 최근에는 도 2와 같이, 드레인호스(143)를 구비하지 않고 냉각수배출구(141) 만으로 냉각수가 드레인되도록 함으로써, 부품과 원가를 절감하는 경우도 있지만, 이 경우에는 냉각수배출구(141)로 배출된 냉각수가 저장탱크(101)의 외표면으로 흘러내리면서 저장탱크(101)를 비롯한 주변의 엔진룸 내부를 오염시키는 문제점이 발생하였다. Accordingly, recently, as shown in FIG. 2, the cooling water is discharged only by the cooling water discharge port 141 without the drain hose 143, thereby reducing the parts and the cost. In this case, the cooling water discharge port 141 is discharged. As the coolant flowed down to the outer surface of the storage tank 101, there was a problem of contaminating the inside of the engine room including the storage tank 101.

따라서, 본 발명의 목적은 드레인호스를 사용하지 않으면서 냉각수가 원활하게 드레인될 수 있도록 하여 부품과 원가를 절감함과 동시에, 드레인되는 냉각수에 의해 저장탱크를 비롯한 주변이 오염되는 것을 방지할 수 있는 차량용 냉각수 저장탱크를 제공하는 것이다.

The object of the present invention is to provide a cooling water storage tank for a vehicle having a storage tank (1) for receiving cooling water and a cooling water discharge port (41) for discharging the cooling water overflowed and formed in an upper region of the storage tank (1). The discharge water is formed in an upper region of the storage tank 1 adjacent to the lower portion of the cooling water discharge port 41 to receive the discharged water discharged from the cooling water discharge port 41, and the discharge water outlet 49 is formed in one region. A receiver 45; It is achieved by the vehicle cooling water storage tank, characterized in that it comprises an internal drain flow path 43 is formed integrally inside the storage tank 1 from the drain outlet 49 toward the lower outer side of the storage tank (1). do.

As shown in these drawings, the vehicle cooling water storage tank according to the present invention is formed in the storage tank 1 for receiving the coolant and the bottom region of the storage tank 1, like a general cooling water storage tank, radiator (not shown) And a coolant inlet 21 connected to an overflow pipe (not shown), a coolant inlet (not shown) formed on an upper surface of the storage tank 1 for replenishing the coolant, and a reservoir for opening and closing the coolant inlet (not shown). Has a cap 32; It further includes a cooling water discharge port 41 and the internal drain structure 40 for discharging the cooling water overflowed in the storage tank (1) to the outside.

이 중 저장탱크(1)와 냉각수유입구(21) 및 냉각수주입구(미도시)와 리저버캡(32)은 그 구조가 일반적인 냉각수 저장탱크와 거의 동일하므로 자세한 설명은 생략하고, 이하에서는 냉각수배출구(41)와 내부드레인구조(40)에 대해서만 상세하게 설명한다. Among these, the storage tank 1, the coolant inlet 21, the coolant inlet (not shown), and the reservoir cap 32 have almost the same structure as the general coolant storage tank, and thus, detailed description thereof will be omitted, hereinafter, the coolant outlet 41 ) And the internal drain structure 40 will be described in detail.

냉각수배출구(41)는 저장탱크(1)의 상부영역 일측에 거의 니플형상으로 돌출된 구조로 형성될 수 있다. 이 냉각수배출구(41)는 저장탱크(1)의 내부와 외부를 연통시키는 것으로서, 저장탱크(1) 내부에 냉각수가 과도하게 유입되어 수위가 냉각수배출구(41)까지 상승하게 되면 냉각수배출구(41)를 통해 저장탱크(1) 내부에 수용된 냉각수가 외부로 배출된다. The cooling water discharge port 41 may be formed in a structure that protrudes in an almost nipple shape on one side of the upper region of the storage tank 1. The cooling water discharge port 41 communicates the inside and the outside of the storage tank 1. When the cooling water is excessively introduced into the storage tank 1 and the water level rises to the cooling water discharge port 41, the cooling water discharge port 41 is formed. Cooling water contained in the storage tank 1 is discharged through the outside.

한편, 내부드레인구조(40)는 냉각수배출구(41)로 배출된 냉각수를 수령하는 배출수수령부(45)와, 배출수수령부(45)로 수령된 냉각수를 저장탱크(1) 하부 영역으로 배출시키는 내부드레인유로(43)로 이루어져 있다. On the other hand, the internal drain structure 40 to discharge the cooling water discharged to the cooling water discharge port 41, the discharge water receiving portion 45 and the cooling water received by the discharge water receiving portion 45 to the storage tank (1) lower region. It consists of an internal drain flow path 43.

배출수수령부(45)는 냉각수배출구(41)의 하부에 인접한 저장탱크(1) 상부 영역에 수평면이 소정의 경사도를 가지고 함몰된 함몰면(47)과, 경사진 함몰면(47)에 후술할 내부드레인유로(43)의 입구로 형성되는 드레인배출구(49)로 이루어져 있다. 그리고, 내부드레인유로(43)는 저장탱크(1) 내부에서 드레인배출구(49)로부터 저장탱크(1)의 하부로 관통되는 수직방향으로 형성되어 있다. The discharge water receiving part 45 may be described later on the recessed surface 47 and the inclined recessed surface 47 in which the horizontal surface is recessed with a predetermined inclination in the upper region of the storage tank 1 adjacent to the lower portion of the cooling water discharge port 41. It consists of a drain discharge port 49 formed as an inlet of the inner drain flow path (43). The inner drain passage 43 is formed in the storage tank 1 in a vertical direction penetrating from the drain outlet 49 to the lower portion of the storage tank 1.

여기서, 배출수수령부(45)와 드레인배출구(49) 및 내부드레인유로(43)는 저장탱크(1)에 일체로 형성되는 것으로서, 저장탱크(1)의 사출성형시 형성되는 것이 바람직하다. 그리고, 저장탱크(1)는 상부탱크(11)와 하부탱크(13)로 사출성형된 후 상호 상하 방향에서 결합되어 그 내부에 하나의 냉각수 저장공간을 형성하는 구조를 가질 수도 있다. 이때, 배출수수령부(45)와 드레인배출구(49)는 상부탱크(11)의 상부 영역 일측에 형성되고, 내부드레인유로(43)는 배출수수령부(45)의 드레인배출구(49)에 대응하는 영역의 상부탱크(11) 및 하부탱크(13)의 내부 일측에 형성되어 상부탱크(11)와 하부탱크(13)의 결합에 의해 하나의 유로로 형성된다. Here, the discharge water receiving portion 45, the drain discharge port 49 and the inner drain flow path 43 is formed integrally with the storage tank 1, it is preferably formed during the injection molding of the storage tank (1). In addition, the storage tank 1 may have a structure that is injection molded into the upper tank 11 and the lower tank 13 and then coupled in the vertical direction to form one cooling water storage space therein. In this case, the discharge water receiving portion 45 and the drain discharge port 49 are formed at one side of the upper region of the upper tank 11, and the inner drain passage 43 corresponds to the drain discharge port 49 of the discharge water receiving portion 45. It is formed on one side of the upper tank 11 and the lower tank 13 of the region is formed in one flow path by the combination of the upper tank 11 and the lower tank (13).

그리고, 내부드레인유로(43)는 저장탱크(1)의 내측벽 모서리 영역에 접하도록 형성되는 것이 저장탱크(1)의 사출성형이 내부드레인유로(43)를 용이하게 형성할 수 있어 바람직하다. In addition, the inner drain flow path 43 is preferably formed to be in contact with the inner wall edge region of the storage tank 1, so that the injection molding of the storage tank 1 can easily form the inner drain flow path 43.

한편, 배출수수령부(45)의 둘레영역에는 도 5 및 도 6에 도시된 바와 같이, 넘침방지턱(45a)이 형성되는 것이 바람직하다. 이 넘침방지턱(45a)은 냉각수배출구(41)를 통해 과도한 양의 냉각수가 배출될 경우에, 배출수수령부(45)에서 냉각수가 체류하면서 저장탱크(1)의 외표면으로 넘쳐흐르는 것을 방지하기 위한 구조이다. On the other hand, as shown in Figure 5 and Figure 6, the discharge area receiving portion 45, it is preferable that the overflow preventing jaw (45a) is formed. The overflow preventing jaw 45a is for preventing excessive flow of coolant through the coolant outlet 41 to prevent the coolant from overflowing to the outer surface of the storage tank 1 while the coolant stays at the discharge water receiver 45. Structure.

이 넘침방지턱(45a)의 높이는 여건에 따라 자유롭게 변경 가능한 것으로서, 냉각수배출구(41)를 통해 냉각수가 과도하게 넘치는 것이 예상될 경우 넘침방지턱(45a)의 높이를 냉각수배출구(41)의 상부 영역까지 높게 형성할 수 있다. The height of the overflow bump 45a is freely changeable according to conditions, and when the coolant is excessively overflowed through the coolant outlet 41, the height of the overflow bump 45a is increased to the upper region of the coolant outlet 41. Can be formed.

이러한 구성을 갖는 본 발명에 따른 차량용 냉각수 저장탱크(1)는 라디에이터(미도시)에서의 냉각수 온도상승 및 비정상적인 압력에 의한 냉각수의 체적 증가 등의 이유로 오버플로우관(미도시)을 통해 냉각수가 저장탱크(1)로 과도하게 유입되면, 도 4 및 도 6에 화살표로 도시된 바와 같이, 냉각수가 냉각수배출구(41)를 통해 배출된 다음, 배출수수령부(45)로 흘러내린다. The cooling water storage tank 1 for vehicles according to the present invention having such a configuration stores the coolant through an overflow pipe (not shown) due to a rise in the coolant temperature in a radiator (not shown) and an increase in the volume of the coolant due to abnormal pressure. When excessively flowed into the tank 1, as shown by the arrow in Figs. 4 and 6, the cooling water is discharged through the cooling water discharge port 41, and then flows to the discharge water receiving portion 45.

그런 다음, 배출수수령부(45)의 경사진 함몰면을 따라 드레인배출구(49)와 내부드레인유로(43)를 통해 저장탱크(1)의 하부 외측 영역으로 배출됨으로써, 드레인되는 냉각수를 저장탱크(1)의 하부 외측으로 원활하게 배출할 수 있다. Then, the water is discharged to the lower outer region of the storage tank 1 through the drain outlet 49 and the inner drain passage 43 along the inclined recessed surface of the discharge water receiving part 45, thereby storing the coolant drained in the storage tank ( It can be discharged smoothly to the outside of the lower part of 1).

이와 같이, 본 발명에 따른 차량용 냉각수 저장탱크(1)는 냉각수배출구(41)로부터 배출된 냉각수가 배출수수령부(45)에서 저장탱크(1) 내부에 형성된 내부드레인유로(43)를 통해 외부로 배출됨으로써, 별도의 드레인호스를 이용하지 않고도 드레인된 냉각수를 외부로 원활하게 배출할 수 있다. 이에 의해, 부품과 원가가 절감된다. As described above, the vehicle cooling water storage tank 1 according to the present invention is externally provided by the coolant discharged from the cooling water discharge port 41 through the inner drain passage 43 formed inside the storage tank 1 at the discharge water receiving part 45. By discharging, the drained cooling water can be smoothly discharged to the outside without using a separate drain hose. This reduces the parts and the cost.

또한, 냉각수배출구(41)로 배출된 냉각수가 내부드레인유로(43)를 통해 저장탱크(1) 하부 외측으로 배출됨으로써, 저장탱크(1) 외표면을 비롯한 그 주변의 엔진룸을 오염시키지 않고 냉각수가 배출된다. In addition, the coolant discharged to the coolant discharge port 41 is discharged to the outside of the lower portion of the storage tank 1 through the inner drain flow passage 43, so that the coolant is not polluted without contaminating the engine room including the outer surface of the storage tank 1. Is discharged.
