서지탱크 일체형 ＬＮＧ 기화기{THE CARBURETTER FOR LNG INTEGRATED SURGE TANK}Surge tank integrated type carburetor {THE CARBURETTER FOR LNG INTEGRATED SURGE TANK}

본 발명은 LNG를 연료로 사용하는 차량에 구비되어 LNG를 기화시키는 기화기에 관한 것이다. The present invention relates to a vaporizer provided in a vehicle using LNG as a fuel to vaporize LNG.

LNG와 경유를 혼합하여 연료로 사용하는 LNG 혼소 자동차 등에는 LNG를 기화시키기 위한 기화기 및 기화된 LNG가스를 엔진에 안정적으로 공급하기 위해 기화된 LNG가스를 다량 보관해두는 서지탱크가 구비되어 있다.LNG mixed-cars, such as LNG and diesel, used as fuel, are equipped with a vaporizer for vaporizing LNG and a surge tank for storing a large amount of vaporized LNG gas to stably supply the vaporized LNG gas to the engine.

일반적으로 상기와 같은 종래의 기화기는, 엔진을 경유하면서 가열된 냉각수가 기화기의 하우징 내로 유입되고, 하우징의 내부에 위치된 열교환파이프를 따라 액체상태인 저온의 LNG가 유동되면서 냉각수와 LNG 간에 열교환이 이루어져 lNG의 기화가 이루어지는 형태로 되어 있었다. In general, such a conventional carburetor, the cooling water heated while passing through the engine is introduced into the housing of the carburetor, and the heat exchange between the cooling water and the LNG as the liquid low temperature LNG flows along the heat exchange pipe located inside the housing. It was in the form of vaporization of lNG.

또, 서지지탱크는 급가속, 추월, 오르막길 운행 등 다량의 연료가 소모되는 출력조건에서 엔진에 연료를 안정적으로 공급하기 위해 구비되는 것으로서 기화기 와 연결됨에 있어서는 별도의 배관을 통해 연결되고 있었다. In addition, the support tank is provided for stably supplying fuel to the engine under the output conditions in which a large amount of fuel is consumed such as rapid acceleration, overtaking, and uphill driving, and is connected through a separate pipe when connected to the carburetor.

종래에는 상기와 같이 기화기와 서지탱크가 일정한 간격을 두고 별도의 배관에 의해 연결됨에 따라 엔진의 출력이 기대에 미치지 못하는 현상이 발생되고, 제조비용을 상승시키는 문제점이 있었다. Conventionally, as the carburetor and the surge tank are connected by separate pipes at regular intervals as described above, a phenomenon occurs that the output of the engine does not meet expectations, and there is a problem of increasing the manufacturing cost.

즉, 기화기와 서지탱크를 연결하는 배관으로 인해 기화된 LNG 가스의 공급량에 편차가 발생되고, 기화된 LNG 가스의 온도에 차이가 발생되는 등의 이유로 엔진의 출력이 저하되는 현상이 발생되고, 배관자재 및 그 설치로 인한 인건비 상승 등의 이유로 차량의 제조비용이 상승하는 문제점이 발생되었던 것이다. That is, due to a pipe connecting the carburetor and the surge tank, a deviation occurs in the supply amount of vaporized LNG gas, and a difference occurs in the output of the engine due to a difference in the temperature of the vaporized LNG gas. There is a problem that the manufacturing cost of the vehicle increases due to the increase in labor costs due to the material and its installation.

본 발명은 상기와 같은 문제점을 해소하려는 것으로서, 더욱 상세하게는 급가속, 추월, 오르막길 운행 등 다량의 연료가 빠르게 소모되는 출력조건에서도 기화된 LNG 가스의 공급량 및 온도에 차이가 발생되는 것을 최소화하여 엔진 출력저하 현상을 최소화할 수 있으며, 차량의 제조비용 등을 낮출 수 있는 서지탱크 일체형 LNG 기화기를 제공하려는데 목적이 있다.The present invention is to solve the above problems, more specifically, by minimizing the difference in the supply amount and temperature of the vaporized LNG gas even in the output conditions, such as rapid acceleration, overtaking, uphill operation, a large amount of fuel is quickly consumed The purpose of the present invention is to provide an LNG vaporizer integrated with a surge tank, which can minimize an engine output reduction phenomenon and lower the manufacturing cost of a vehicle.

본 발명에서는 기화기와 서지탱크가 일체화된 구조 즉, LNG의 기화가 이루어지는 공간과 기화된 LNG가스가 보관되는 공간이 별도의 배관 없이 연결되고 열교환이 이루어지도록 함으로써 기화된 LNG 가스의 공급량 및 온도에 차이가 발생되는 것을 최소화한다. In the present invention, the structure in which the vaporizer and the surge tank are integrated, that is, the space in which the vaporization of LNG and the space in which the vaporized LNG gas is stored is connected without a separate pipe and the heat exchange is performed, thereby making a difference in the supply amount and temperature of the vaporized LNG gas. Minimize the occurrence of

따라서 본 발명의 기화기는, 차량의 냉각수가 유입, 유출되면서 채워지는 냉각수충진공간이 형성되어 있고, 냉각수충진공간을 경유한 LNG가 유입, 유출되면서 채워지는 서지탱크공간이 형성되어 있되 냉각수충진공간과 서지탱크공간은 열교환이 이루어지도록 분리되어 있는 하우징을 갖는다.Therefore, the carburetor of the present invention is formed with a coolant filling space filled with the cooling water inlet and outflow of the vehicle, and a surge tank space filled with the inflow and outflow of LNG passing through the coolant filling space, but the coolant filling space and The surge tank space has a housing separated for heat exchange.

또, 하우징의 냉각수충진공간에 위치되어 외부로부터 공급되는 LNG가 냉각수충진공간을 경유하여 서지탱크공간에 채워지도록 하되 LNG가 냉각수충진공간을 경유하는 과정에서 기화되도록 하는 열교환파이프를 갖는다. In addition, there is a heat exchange pipe positioned in the cooling water filling space of the housing so that the LNG supplied from the outside is filled in the surge tank space via the cooling water filling space, but the LNG is vaporized in the process of passing through the cooling water filling space.

본 발명의 LNG기화기는 서지탱크가 일체화된 구조 즉, LNG의 기화가 이루어지는 공간과 기화된 LNG가스가 보관되는 공간이 별도의 배관 없이 연결되고 상호 열교환이 이루어지도록 되어 있어 기화된 LNG 가스의 공급량 및 온도에 차이가 발생되는 것을 최소화할 수 있다. LNG vaporizer of the present invention is a structure in which the surge tank is integrated, that is, the space in which the vaporization of LNG and the space in which the vaporized LNG gas is stored are connected to each other without a separate pipe and mutual heat exchange is performed so that the supply amount of vaporized LNG gas and The difference in temperature can be minimized.

따라서 급가속, 추월, 오르막길 운행 등 다량의 연료가 빠르게 소모되는 출력조건에서도 엔진 출력저하 현상을 최소화할 수 있으며, 차량의 제조비용을 낮출 수 있다. Therefore, the engine output reduction phenomenon can be minimized even in output conditions such as rapid acceleration, overtaking, and uphill driving, where a large amount of fuel is rapidly consumed, and the manufacturing cost of the vehicle can be lowered.

본 발명에서, 열교환파이프가 복수 개 구비된 경우 LNG의 기화를 위한 열교환이 더욱 원활하게 이루어져 기화된 LNG 가스의 공급이 더욱 원활하므로 출력저하 현상이 더욱 방지된다. In the present invention, when a plurality of heat exchange pipes are provided, the heat exchange for vaporization of the LNG is more smoothly, so that the supply of vaporized LNG gas is more smooth, and thus the output reduction phenomenon is further prevented.

본 발명에서 기화기를 이루는 하우징의 내측면이 스테인레스 재질로 이루어진 경우 내부식성이 우수한 특징이 있다. In the present invention, when the inner surface of the housing constituting the vaporizer is made of a stainless material is characterized by excellent corrosion resistance.

본 발명의 서지탱크공간 중 LNG가 유출되는 부근에서는 LNG의 유출 방향으로 갈수록 폭이 점차 좁아지는 구조를 가지면 LNG 가스의 공급이 더욱 더 원활하므로 출력저하 현상이 더욱 더 방지되는 특징이 있다.In the surge tank space of the present invention in the vicinity of the outflow of the LNG has a structure that gradually narrows in the direction of the outflow of the LNG has a feature that even more smoothly the supply of LNG gas output reduction phenomenon is further prevented.

이하, 본 발명의 기술적 사상을 첨부된 도면을 사용하여 더욱 구체적으로 설명한다. Hereinafter, the technical spirit of the present invention will be described in more detail with reference to the accompanying drawings.

그러나 첨부된 도면은 본 발명의 기술적 사상을 더욱 구체적으로 설명하기 위하여 도시한 일 예에 불과하므로 본 발명의 기술적 사상을 첨부된 도면의 형태에 한정되는 것은 아니다. However, the accompanying drawings are only examples to illustrate the technical idea of the present invention in more detail, and thus the technical idea of the present invention is not limited to the accompanying drawings.

본 발명은 LNG를 연료로 사용하는 차량에 구비되어 LNG를 기화시키는 기화기에 관한 것이다.The present invention relates to a vaporizer provided in a vehicle using LNG as a fuel to vaporize LNG.

따라서 차량의 냉각수가 유입, 유출되면서 채워지는 냉각수충진공간(11)이 형성되어 있는 하우징(10)을 갖는다. Therefore, the vehicle 10 has a housing 10 in which a coolant filling space 11 is filled while the coolant of the vehicle is introduced or discharged.

또, 하우징(10)의 냉각수충진공간(11)에 위치되어 외부로부터 공급되는 LNG가 냉각수충진공간(11)을 경유하면서 기화되도록 하는 열교환파이프(20)를 갖는다.In addition, the heat exchange pipe 20 is positioned in the cooling water filling space 11 of the housing 10 so that LNG supplied from the outside is vaporized while passing through the cooling water filling space 11.

그런데 본 발명은 급가속, 추월, 오르막길 운행 등 다량의 연료가 소모되는 출력조건에서도 기화된 LNG 가스의 공급량 및 온도에 차이가 발생되는 것을 최소화하여 엔진 출력저하 현상을 최소화할 수 있으며, 차량의 제조비용 등을 낮출 수 있는 기화기를 제공하려는 목적을 갖는다. However, the present invention can minimize the engine output reduction phenomenon by minimizing the difference in the supply amount and temperature of the vaporized LNG gas even in the output conditions such as rapid acceleration, overtaking, uphill driving, which consumes a large amount of fuel, and manufacture of the vehicle. The purpose is to provide a carburetor that can lower the cost and the like.

이러한 목적을 달성하기 위하여 본 출원의 발명자는 서지탱크 일체형 LNG 기화기의 구조를 안출하였다. In order to achieve this object, the inventor of the present application devised a structure of a surge tank integrated LNG vaporizer.

이러한 본 발명의 기화기는, 차량의 냉각수가 유입, 유출되면서 채워지는 냉각수충진공간(11)이 형성되어 있고, 냉각수충진공간(11)을 경유한 LNG가 유입, 유출되면서 채워지는 서지탱크공간(12)이 형성되어 있되 냉각수충진공간(11)과 서지탱크공간(12)은 열교환이 이루어지도록 분리되어 있는 하우징(10)을 갖는다. The carburetor of the present invention, the cooling water filling space 11 is filled with the cooling water inlet, outflow is formed, the surge tank space 12 is filled while the LNG flowing through the cooling water filling space 11, 12 ) Is formed, but the cooling water filling space 11 and the surge tank space 12 has a housing 10 is separated so that heat exchange takes place.

또, 하우징(10)의 냉각수충진공간(11)에 위치되어 외부로부터 공급되는 LNG 가 냉각수충진공간(11)을 경유하여 서지탱크공간(12)에 채워지도록 하되 LNG가 냉각수충진공간(11)을 경유하는 과정에서 기화되도록 하는 열교환파이프(20)를 갖는다.In addition, the LNG is located in the coolant filling space 11 of the housing 10 so that LNG supplied from the outside is filled in the surge tank space 12 via the coolant filling space 11, but LNG is filled in the coolant filling space 11. It has a heat exchange pipe 20 to be vaporized in the process of passing.

즉, 기화기와 서지탱크가 각각 별도로 구비되고 별도의 배관을 통해 연결되는 것이 아니라 하나의 하우징(10) 내에 LNG의 기화를 위한 냉각수충진공간(11)과 기화된 가스를 다량 확보해놓고 엔진으로 공급하기 위한 서지탱크공간(12)이 구비되도록 하는 것이다. That is, the carburetor and the surge tank are provided separately and connected through separate pipes, and supplying a large amount of coolant filling space 11 and vaporized gas to vaporize the LNG in one housing 10 and supplying it to the engine. The surge tank space 12 is to be provided.

또, 냉각수충진공간(11)과 서지탱크공간(12)이 열교환됨으로써 기화된 LNG 가스가 서지탱크공간(12)을 경유하는 과정에서 온도의 변화 및 밀도의 변화가 발생되지 않도록 하는 것이다. In addition, the cooling water filling space 11 and the surge tank space 12 are heat-exchanged so that vaporized LNG gas is not changed in temperature and density in the course of passing through the surge tank space 12.

또, 기화된 LNG 가스가 서지탱크공간(12)으로 원활하게 공급되도록 하는 것이며, 기화기와 서지탱크를 연결하던 배관 및 연결을 위한 장치가 필요하지 않도록 함으로써 제조원가를 낮출 수 있도록 하는 것이다.(별도의 배관을 통해 기화기와 서지탱크를 연결하는 경우 배관의 직경이 작고 구부러지는 경우가 많기 때문에 기화된 LNG의 공급이 원활하지 못할 뿐만 아니라 배관을 경유하는 과정에서 기화된 LNG 가스의 온도가 변하게 된다.)In addition, the vaporized LNG gas is to be smoothly supplied to the surge tank space 12, and the manufacturing cost can be lowered by eliminating the need for a pipe and a connection device connecting the vaporizer and the surge tank. When connecting the carburetor and the surge tank through the pipe, the diameter of the pipe is small and often bent, so the supply of the vaporized LNG is not smooth, and the temperature of the vaporized LNG gas is changed during the passage.

본 발명의 구성요소인 열교환파이프(20)는 복수 개 구비되는 것이 열교환 효율을 향상시킬 수 있어 바람직하다.It is preferable that a plurality of heat exchange pipes 20, which are components of the present invention, be provided to improve heat exchange efficiency.

즉, 저온의 LNG가 복수 개의 열교환파이프(20)를 통해 공급됨으로써 열교환 면적이 넓어 열교환 효율이 우수하도록 하는 것이다. That is, the low temperature LNG is supplied through the plurality of heat exchange pipes 20 so that the heat exchange area is wide so that the heat exchange efficiency is excellent.

이와 같이 열교환 효율이 우수하면 LNG의 기화능력이 향상되므로 서지탱크로 기화된 LNG 가스를 원활하게 공급할 수 있고, 이로 인해 급가속, 추월, 오르막길 운행 등 다량의 연료가 소모되는 출력조건에서도 기화된 LNG 가스를 엔진으로 공급하는 것이 원활하다.In this way, if the heat exchange efficiency is excellent, the vaporization capacity of LNG is improved, so that the LNG gas can be smoothly supplied to the surge tank, and as a result, the LNG vaporized even in output conditions such as rapid acceleration, overtaking, and uphill driving. Supplying gas to the engine is smooth.

첨부된 도면에서는 2개의 코일형 열교환파이프(20)가 위치되어 있고, 이 2개의 코일형 열교환파이프(20)는 하우징(10)의 양측에 연결된 어댑터(30)에 각각 연결되어 있다. In the accompanying drawings, two coil type heat exchange pipes 20 are located, and the two coil type heat exchange pipes 20 are connected to adapters 30 connected to both sides of the housing 10, respectively.

즉, 열교환파이프(20)의 연결을 위한 어댑터(30)를 가지며, 이 어댑터(30)는 복수 개(도면에서는 2개)의 파이프연결구를 가지고 있어 복수 개의 열교환파이프(20)를 연결할 수 있도록 된 것이다.That is, it has an adapter 30 for the connection of the heat exchange pipe 20, the adapter 30 has a plurality of pipe connectors (two in the figure) to be able to connect a plurality of heat exchange pipe (20) will be.

본 발명에 있어서, 하우징(10)의 내측면은 내부식성이 우수한 스테인레스로 구현하여 차량의 냉각수나 LNG에 의한 부식을 최소화하는 것이 바람직하다. In the present invention, it is preferable that the inner surface of the housing 10 is made of stainless steel having excellent corrosion resistance to minimize corrosion of the vehicle's cooling water or LNG.

스테인레스 계열 중에서도 SUS304가 바람직하다. Among stainless series, SUS304 is preferable.

본 발명에 있어서, 서지탱크공간(12) 중 LNG가 유출되는 부근에서는 LNG의 유출 방향으로 갈수록 폭이 점차 좁아지는 형태로 구현하는 것이 바람직하다. In the present invention, in the vicinity of the outflow of LNG in the surge tank space 12, it is preferable to implement in the form that the width gradually narrowed toward the outflow direction of the LNG.

즉, LNG의 유출 방향으로 갈수록 유체저항이 작아지도록 하는 것이다. In other words, the fluid resistance decreases toward the outflow direction of LNG.

이러한 형상은 서지탱크공간(12) 내의 기화된 LNG 가스가 엔진으로 원활하게 공급되도록 하는 특징이 있다. This shape is characterized in that the vaporized LNG gas in the surge tank space 12 is smoothly supplied to the engine.

첨부된 도면에서는 서지탱크공간(12) 중 LNG가 유출되는 부근이 반구형의 형상으로 되어 있어 폭이 점차 좁아지고, 이로 인해 서지탱크공간(12)의 LNG 가스가 엔진으로 원활하게 공급되도록 되어 있다.
