Description

차량 냉각시스템의 냉각수 리저버 탱크 {a reservoir tank for a vehicle's cooling system}Coolant reservoir tank for vehicle cooling system {a reservoir tank for a vehicle's cooling system}

본 발명은 냉각시스템이 고압일 때에 라디에이터로부터 흘러나오는 냉각수를 저장하였다가 냉각 시스템의 압력이 낮아진 때에 다시 라디에이터로 공급할 수 있도록 하는 냉각수 리저버 탱크에 관한 것으로, 더 자세하게는 냉각수 리저버 탱크의 용량을 늘리지 않고 냉각수 리저버 탱크내 냉각수 용량을 능동적으로 제어하여 냉각수 오버플로우를 방지할 수 있도록 한 것에 관한 것이다.The present invention relates to a coolant reservoir tank which stores the coolant flowing out of the radiator when the cooling system is at a high pressure and supplies it to the radiator again when the pressure of the cooling system is reduced. More specifically, the present invention relates to a coolant reservoir tank without increasing the capacity of the coolant reservoir tank. The present invention relates to actively controlling the coolant capacity in the coolant reservoir tank to prevent the coolant overflow.

도 1에는 종래의 냉각수 리저버 탱크의 장착상태의 종단면도가 도시되어 있다.Figure 1 is a longitudinal sectional view of the mounting state of a conventional coolant reservoir tank.

도 1과 같이 종래의 냉각수 리저버 탱크(100')는 드레인관(112')을 통해 라디에이터(200')의 압력캡(201')과 접속되는 유입구(111')가 일측 하부에 마련되고, 일측 상부에 오버플로우관(114')이 접속되는 배출구(113')가 마련되며, 상단 일측에 밀폐캡(116')이 설치되는 주입구(115')가 마련되는 형태를 갖는다.As shown in FIG. 1, the conventional coolant reservoir tank 100 ′ has an inlet 111 ′ connected to the pressure cap 201 ′ of the radiator 200 ′ through a drain pipe 112 ′ and is provided at one lower side thereof. The outlet 113 'is provided to the overflow pipe 114' is connected to the upper portion, the inlet 115 'is provided with a sealing cap 116' is installed on one side of the upper end.

차량의 냉각 시스템에 있어서는 냉각수의 온도가 상승하고 압력이 일정압력이상(예를 들면 1.1bar 이상)으로 상승되면 라디에이터 압력캡(201')의 압력밸브가 열리게 되고, 드레인관(112')을 통하여 라디에이터(200')의 냉각수가 냉각수 리저버 탱크(100') 측으로 흐르게 된다.In a vehicle cooling system, when the temperature of the cooling water rises and the pressure rises above a certain pressure (for example, 1.1 bar or more), the pressure valve of the radiator pressure cap 201 'opens, and the drain pipe 112' The coolant of the radiator 200 ′ flows to the coolant reservoir tank 100 ′.

그리고 엔진이 식어서 냉각수의 부피가 줄어들어 냉각 시스템이 대기압 아래로 떨어지면 압력캡(201')의 부압밸브가 열리게 되고, 드레인관(112')을 통하여 냉각수 리저버 탱크(100') 내부의 냉각수가 라디에이터(200') 측으로 빨려 들어가게 된다.When the engine cools down and the volume of the cooling water decreases and the cooling system falls below atmospheric pressure, the negative pressure valve of the pressure cap 201 'opens, and the cooling water inside the cooling water reservoir tank 100' opens through the drain pipe 112 '. It is sucked into the (200 ') side.

한편 차량이 저속 고부하 조건에서 주행 후 키-오프(Key-off) 시 라디에이터(200)로 들어오는 냉각풍이 없어져 냉각수 온도가 일정 시간동안 상승하는 현상이 발생하게 되고, 이때 냉각 시스템의 압력이 일정압력이상(예를 들면 1.1bar 이상)이 되어 라디에이터(200')의 냉각수가 냉각수 리저버 탱크(100')로 이동하게 되는데, 그 이동량이 일정치 않고 냉각수 리저버 탱크(100')의 용량은 한계가 있어서 냉각수의 오버플로우 현상이 나타나게 된다.On the other hand, when the vehicle is driven under low speed and high load conditions, the cooling air entering the radiator 200 disappears when the key is turned off and the cooling water temperature rises for a predetermined time, and the pressure of the cooling system is higher than the predetermined pressure. (For example, 1.1 bar or more), the coolant of the radiator 200 'is moved to the coolant reservoir tank 100', but the amount of movement of the radiator 200 'is not constant and the capacity of the coolant reservoir tank 100' is limited. The overflow phenomenon of appears.

종래에는 전술한 냉각수 오버플로우 현상을 방지하기 위하여 냉각수 리저버 탱크(100')의 용량을 늘리는 방법을 사용하였지만 엔진룸의 공간적 제약으로 냉각수 리저버 탱크(100')의 용량을 늘리는 데는 한계가 있는 실정이었다.Conventionally, the method of increasing the capacity of the coolant reservoir tank 100 'is used to prevent the coolant overflow, but there is a limit to increasing the capacity of the coolant reservoir tank 100' due to the space constraint of the engine room. .

또한 전술한 냉각수 오버플로우 현상을 방지하기 위하여 주행중 냉각수온도를 낮추는 방법이 있으나 이는 냉각계 용량 증대를 필요로 하여 추가로 중량과 원가상승이 되는 문제가 있었다.In addition, there is a method of lowering the coolant temperature while driving to prevent the above coolant overflow phenomenon, but this requires an increase in the capacity of the cooling system, thereby causing additional weight and cost increase.

본 발명은 상기와 같은 종래의 실정을 감안하여 안출한 것이며, 그 목적이 냉각수 리저버 탱크의 용량을 늘리지 않고 냉각수 리저버 탱크내 냉각수 용량을 능동적으로 제어하여 냉각수의 과도한 오버플로우를 방지할 수 있도록 하는 차량 냉각시스템의 냉각수 리저버 탱크를 제공하는 데에 있는 것이다.The present invention has been made in view of the conventional situation as described above, the object of the vehicle to actively control the cooling water capacity in the cooling water reservoir tank without increasing the capacity of the cooling water reservoir tank to prevent excessive overflow of the cooling water It is to provide a coolant reservoir tank for the cooling system.

The pressure control spring 123 is installed.

도 3에는 본 발명의 한 실시예의 작동상태도가 도시되어 있는 바, 도 3을 참조하면서 본 발명의 냉각수 리저버 탱크(100)를 장착한 때의 작동을 설명하면 다음과 같다.3 shows an operation state diagram of an embodiment of the present invention. Referring to FIG. 3, the operation when the coolant reservoir tank 100 of the present invention is mounted will be described below.

차량의 저속 고부하 조건에서 운전한 후 시동 오프 시 냉각수 온도가 상승되고 냉각 시스템 압력이 일정압력이상으로 상승되어 압력캡(201)의 압력밸브가 열리게 되면 라디에이터(200)의 냉각수가 압력캡(201)에서 드레인관(112)을 따라 냉각수 리저버 탱크(100)로 이동하게 된다.Cooling water temperature of the radiator 200 when the pressure valve of the pressure cap 201 is opened when the coolant temperature rises and the cooling system pressure rises above a certain pressure when the engine is started off after driving under a low speed and high load condition of the vehicle. In the movement to the coolant reservoir tank 100 along the drain pipe (112).

상기에서 냉각수 리저버 탱크(100)의 유입구(111)로 진입하는 냉각수는 유입구(111)를 밀폐하던 부구(122)를 상승시켜 유입구(111)를 개방하게 되고, 유입구(111)를 통해 냉각수가 유입되어 부구 승강가이드공간(121)을 포함한 냉각수 리저버 탱크(100) 내부 수위가 상승되며, 냉각수 리저버 탱크(100) 내부에 냉각수가 가득 차게 되면 부구(122)의 상단부가 압력조절스프링(123)의 하단에 접촉되면서 배출구(113)를 막게 되어 냉각수의 오버플로우를 방지하게 된다.Cooling water entering the inlet 111 of the coolant reservoir tank 100 in the above rises the sub-hole 122 sealing the inlet 111 to open the inlet 111, the coolant flows through the inlet 111 The water level inside the coolant reservoir tank 100 including the float lifting guide space 121 is increased, and when the coolant is filled inside the coolant reservoir tank 100, the upper end of the float 122 is the lower end of the pressure regulating spring 123. While contacting the outlet 113 is blocked to prevent the overflow of the coolant.

상기에서 배출구(113)가 막힌 상태에서 계속적으로 냉각수가 유입되어 냉각수 리저버 탱크(100) 내부 압력이 증가하게 되면 부구(122)가 상승되어 압력조절스프링(123)을 압축시키게 되는 동시에 배출구(113)가 개방되어 냉각수가 외부로 배출되며, 냉각수의 배출로 냉각수 리저버 탱크(100) 내부 압력이 저하되면 압축되었던 압력조절스프링(123)이 팽창되면서 부구(122)를 하강시켜 배출구(113)를 다시 밀폐하게 된다.When the coolant is continuously introduced in the state in which the outlet 113 is blocked, and the pressure inside the coolant reservoir tank 100 increases, the float 122 is raised to compress the pressure regulating spring 123 and at the same time the outlet 113. Is opened and the coolant is discharged to the outside, and when the pressure inside the coolant reservoir tank 100 decreases due to the discharge of the coolant, the compressed pressure control spring 123 is expanded and the outlet 122 is closed again to seal the outlet 113 again. Done.

이처럼 부구(122)의 승강 및 배출구(113)의 개폐를 반복하는 과정에서 냉각수의 온도가 저하되면 냉각수 리저버 탱크(100) 내부의 냉각수는 더 이상 오버플로우되지 않게 된다.When the temperature of the cooling water decreases in the process of repeatedly lifting and lowering the outlet 122 and opening and closing of the outlet 122, the cooling water inside the cooling water reservoir tank 100 no longer overflows.

그리고 냉각수가 완전히 식고 냉각 시스템의 압력이 저하되어 라디에이터 압력캡(201)의 부압밸브가 열리게 되면 냉각수 리저버 탱크(100)에서 라디에이터(200)쪽으로 냉각수가 이동하게 된다.When the coolant is completely cooled and the pressure of the cooling system is lowered to open the negative pressure valve of the radiator pressure cap 201, the coolant moves from the coolant reservoir tank 100 toward the radiator 200.

이상에서 설명한 본 발명은 전술한 실시예 및 도면에 의해 한정되는 것은 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경이 가능함은 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 있어 명백할 것이다.The present invention described above is not limited to the above-described embodiments and drawings, and various permutations, modifications, and changes can be made without departing from the technical spirit of the present invention.
