Description

자동차의 냉각수 보조탱크 {A sub tank for reserving cooling water in an automobile}A sub tank for reserving cooling water in an automobile}

본 발명은 자동차의 냉각수 보조탱크에 관한 것으로, 더욱 상세하게는 자동차의 냉각시스템이 과열되더라도 냉각수가 엔진룸으로 비산되는 것을 방지하는 냉각수 보조탱크에 관한 것이다.The present invention relates to a cooling water auxiliary tank of a motor vehicle, and more particularly, to a cooling water auxiliary tank for preventing cooling water from scattering into an engine room even when the cooling system of a vehicle is overheated.

일반적으로, 자동차의 엔진은 연소가스에 의해 고온으로 올라가게 되는데, 이는 기관의 각종부품의 변형을 일으키게 된다. 따라서, 엔진의 과열을 방지하기 위하여 냉각장치가 장착된다.In general, the engine of an automobile is raised to a high temperature by the combustion gas, which causes deformation of various parts of the engine. Thus, a cooling device is mounted to prevent overheating of the engine.

이러한 냉각장치는, 도 1에 도시된 바와 같이, 크게 라디에이터(1)와 냉각수 보조탱크(2)로 구성되며, 라디에이터(1)는 다량의 물을 담을 수 있는 탱크로서 고온의 냉각수의 열이 외기로 배출되도록 방열면적이 큰 코어로 이루어져 있다. 냉각수 보조탱크(2)는 라디에이터(1)내의 냉각수의 체적팽창으로 인해 넘치는 냉각수를 저장할 수 있도록 라디에이터(1)의 뚜껑에서 냉각수 보조탱크(2)와 호스에 의해 서로 연결되어 엔진룸의 소정위치에 장착된다.This cooling device, as shown in Figure 1, largely composed of a radiator 1 and a coolant auxiliary tank (2), the radiator (1) is a tank that can hold a large amount of water, the heat of the coolant of the hot water The core consists of a large heat dissipation area to be discharged into the furnace. The coolant auxiliary tank (2) is connected to each other by a coolant auxiliary tank (2) and a hose at the lid of the radiator (1) so as to store the excess coolant due to the volume expansion of the coolant in the radiator (1) at a predetermined position in the engine room. Is mounted.

냉각수 보조탱크는, 도 2에 도시된 바와 같이, 가압캡(3)과 보조탱크(2)를 포함한다. 가압캡(3)은 흡입관(3a)과 배출관(3b)을 가지고 일체로 성형된다. 흡입관(3a)의 일단에는 라디에이터에 연결되는 호스(4)가 연결된다. 배출관(3b)은 가압캡(3)에서 연장되어 가압캡(3)의 외측으로 향하여 있다. 보조탱크(2)는 라디에이터의 과열로 인해 넘치는 냉각수(5)가 임시로 저장된다. 따라서, 보조탱크(2)의 냉각수(5)가 과열되거나 그 양이 보조탱크(2)가 감당할 수 있는 용적 이상으로 되면, 냉각수(5)는 이 배출관(3b)을 통해 엔진룸으로 비산되어 외부로 배출된다.The cooling water auxiliary tank, as shown in FIG. 2, includes a pressure cap 3 and an auxiliary tank 2. The pressure cap 3 is integrally formed with the suction pipe 3a and the discharge pipe 3b. One end of the suction pipe 3a is connected with a hose 4 connected to the radiator. The discharge pipe 3b extends from the pressure cap 3 and faces toward the outside of the pressure cap 3. The auxiliary tank 2 temporarily stores excess coolant 5 due to overheating of the radiator. Therefore, if the cooling water 5 of the auxiliary tank 2 is overheated or the amount thereof exceeds the volume that the auxiliary tank 2 can afford, the cooling water 5 is scattered to the engine room through the discharge pipe 3b to the outside. To be discharged.

그러나, 상기와 같은 종래의 자동차의 냉각수 보조탱크는 가압캡(3)의 배출관을 통해 배출되는 냉각수가 엔진룸으로 분사되어 엔진룸에 설치된 각종 부품의 수명을 단축시키거나 오염시키는 단점이 있었다.However, the conventional cooling water auxiliary tank of a vehicle as described above has a disadvantage in that the cooling water discharged through the discharge pipe of the pressure cap 3 is injected into the engine room to shorten or contaminate the life of various components installed in the engine room.

본 발명은, 상기와 같은 점을 감안하여 안출된 것으로, 엔진룸의 오염을 미연에 방지하며, 엔진룸에 장착된 각종 부품의 고장을 방지할 수 있는 자동차의 냉각수 보조탱크를 제공하는데 그 목적이 있다.The present invention has been made in view of the above, and the object of the present invention is to provide a cooling water auxiliary tank for an automobile that can prevent pollution of the engine compartment in advance and prevent failure of various components mounted in the engine compartment. have.

상기와 같은 목적을 달성하기 위하여, 본 발명에 따른 자동차의 냉각수 보조탱크는 흡입관을 통해 라디에이터와 연통되어, 라디에이터로부터 흘러넘치는 냉각수를 수용하는 주보조탱크; 및 배출관을 통해 주보조탱크와 연통되며, 주보조탱크로부터 흘러넘치는 냉각수를 수용하는 부보조탱크를 포함한다. 바람직하게는, 냉각수를 외부로 배출하기 위한 유출구가 상기 부보조탱크의 하부에 형성된다.In order to achieve the above object, the cooling water auxiliary tank of the vehicle according to the present invention is in communication with the radiator through the suction pipe, the main auxiliary tank for receiving the cooling water flowing from the radiator; And a subsidiary tank communicating with the main subsidiary tank through a discharge pipe, the subsidiary tank receiving coolant overflowing from the main subsidiary tank. Preferably, an outlet for discharging the cooling water to the outside is formed in the lower portion of the secondary auxiliary tank.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세하게 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명에 따른 냉각수 보조탱크는, 도 3에 도시된 바와 같이, 주보조탱크(10) 및 부보조탱크(20)를 포함한다.Cooling water auxiliary tank according to the present invention, as shown in Figure 3, includes a secondary auxiliary tank 10 and a secondary auxiliary tank (20).

주보조탱크(10)는 상부에 가압캡(11)이 형성된다. 가압캡(11)은 흡입관(11a)과 배출관(11b)을 가지고 가압캡(11)의 상부면에서 흡입관(11a)과 배출관(11b)을 통해 연통되도록 일체로 성형된다. 흡입관(11a)의 일단에는 라디에이터(미도시)에 연결되는 호스(12)가 고정된다. 배출관(11b)은 가압캡(11)에서 연장되어 일단에 호스(12)가 고정된다. 주보조탱크(10)는 흡입관(11a)을 통해 라디에이터와 연통되어, 라디에이터로부터 흘러넘치는 냉각수(30)가 수용된다.The main auxiliary tank 10 is a pressure cap 11 is formed on the top. The pressure cap 11 has an intake pipe 11a and an outlet pipe 11b and is integrally formed to communicate with each other through the suction pipe 11a and the discharge pipe 11b on the upper surface of the pressure cap 11. One end of the suction pipe 11a is fixed with a hose 12 connected to a radiator (not shown). The discharge pipe (11b) is extended from the pressure cap 11 is fixed to the hose 12 at one end. The main auxiliary tank 10 communicates with the radiator through the suction pipe 11a to accommodate the coolant 30 flowing from the radiator.

부보조탱크(20)는 배출관(11b)을 통해 주보조탱크(10)와 연통되며, 주보조탱크(10)로부터 흘러넘치는 냉각수(30)가 수용된다. 부보조탱크(20)는 가압캡(11)의 배출관(11b)의 일단에 고정된 호스(12)의 타단과 연통되며, 호스(12)의 삽입이 용이하도록 부보조탱크(20)의 상부면에 돌출된 돌기부(20a)를 가진다. 따라서, 주보조탱크(10)의 냉각수(30)가 과열되거나 그 양이 주보조탱크(10)가 감당할 수 있는 용적 이상으로 되면, 냉각수(30)는 가압캡(11)의 배출관(11b)을 통해 부보조탱크(20)에 저장된다. 바람직하게는, 부보조탱크(20)의 하부에 냉각수(30)가 외부로 배출되는 유출구(20b)가 형성된다.The secondary auxiliary tank 20 communicates with the main auxiliary tank 10 through the discharge pipe 11b, and receives the coolant 30 flowing from the main auxiliary tank 10. The secondary auxiliary tank 20 communicates with the other end of the hose 12 fixed to one end of the discharge pipe 11b of the pressurizing cap 11 and the upper surface of the secondary auxiliary tank 20 to facilitate insertion of the hose 12. It has a projection 20a protruding into it. Therefore, when the cooling water 30 of the main auxiliary tank 10 is overheated or the amount thereof is larger than the volume that the main auxiliary tank 10 can afford, the cooling water 30 opens the discharge pipe 11b of the pressure cap 11. Through the secondary auxiliary tank 20 is stored. Preferably, an outlet 20b through which the cooling water 30 is discharged to the outside is formed in the lower portion of the subsidiary tank 20.

따라서, 라디에이터의 과열에 따라 냉각수(30)가 가압캡(11)의 흡입관(11a)을 통해 주보조탱크(10)에 임시 저장되고, 주보조탱크(10)의 저장용적 이상이 되면, 가압캡(11)의 배출관(11b)을 통해 연통되는 부보조탱크(20)에 저장된다. 즉, 캡의 배출관(11b)을 통해 엔진룸으로 비산되는 것을 방지하게 된다.Therefore, the coolant 30 is temporarily stored in the main auxiliary tank 10 through the suction pipe 11a of the pressure cap 11 as the radiator is overheated, and when the storage volume of the main auxiliary tank 10 is greater than or equal to the storage volume of the main auxiliary tank 10, the pressure cap It is stored in the secondary auxiliary tank 20 communicated through the discharge pipe (11b) of (11). That is, it is prevented from flying to the engine room through the discharge pipe (11b) of the cap.

상기된 바와 같이, 본 발명에 따른 자동차의 냉각수 보조탱크는 부보조탱크를 설치하여 주보조탱크에서 넘치는 냉각수를 수용함으로써, 엔진룸의 오염이 미연에 방지되며, 엔진룸에 장착된 각종 부품의 고장이 방지되는 효과가 있다.As described above, the cooling water auxiliary tank of the vehicle according to the present invention by installing a secondary auxiliary tank to accommodate the excess coolant in the main auxiliary tank, the contamination of the engine room is prevented in advance, the failure of various components mounted in the engine room This has the effect of being prevented.

이상에서는, 본 발명을 특정의 바람직한 실시예에 대해서 도시하고 설명하였다. 그러나, 본 발명은 상술한 실시예에만 한정되는 것은 아니며, 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자라면 이하의 특허청구범위에 기재된 본 발명의 기술적 사상의 요지를 벗어남이 없이 얼마든지 다양하게 변경실시할 수 있을 것이다.In the above, the present invention has been illustrated and described with respect to certain preferred embodiments.
