이하, 본 고안의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다.Hereinafter, described with reference to the accompanying drawings, preferred embodiments of the present invention is as follows.

도 1과 도 2는 각기 본 고안에 따른 차량용 연료 예열장치의 단면도와 사용상태도이다. 이를 참조하면, 상기 연료 예열장치는 고온의 냉각수가 통과되는 연결관(40)와, 이 연결관(40)의 둘레면에 코일형으로 감겨져 설치되고 연료공급라인(35)에 연결되는 열교환관(50)으로 구성된다.1 and 2 are a cross-sectional view and a state diagram of use of the fuel preheating device for a vehicle according to the present invention, respectively. Referring to this, the fuel preheater is connected to the connection pipe 40 through which the coolant of high temperature passes, and a heat exchanger pipe wound around the circumferential surface of the connection pipe 40 and connected to the fuel supply line 35. 50).

상기 연결관(40)은 알루미늄이나 구리 등의 열전도성이 우수한 소재로 이루어진 관체로서, 그 양측 외주면에는 원판형 사이드패널(43)이 구비되고, 이 사이드패널(43)의 내측면에는 연결관(40)의 외주면에 감겨진 열교환관(50)이 풀려지는 것을 방지하기 위한 걸림돌기(44)가 마련된다.The connecting tube 40 is a tube made of a material having excellent thermal conductivity such as aluminum or copper, and is provided with a disc-shaped side panel 43 on the outer circumferential surfaces of both sides, and a connecting tube (on the inner surface of the side panel 43). A locking projection 44 is provided to prevent the heat exchanger tube 50 wound around the outer circumferential surface of the 40.

또, 상기 사이드패널(43) 사이의 연결관(40) 외주면에는 반원형의 시트홈(41)이 연결관(40)의 외주면을 따라 나선형으로 형성되어 상기 열교환관(50)과 연결관(40)의 접촉면적을 넓혀 열전도율을 향상시킬 수 있도록 구성된다.In addition, a semicircular sheet groove 41 is formed spirally along the outer circumferential surface of the connecting pipe 40 on the outer circumferential surface of the connecting pipe 40 between the side panels 43 so that the heat exchange pipe 50 and the connecting pipe 40 are formed. It is configured to improve the thermal conductivity by widening the contact area of.

또, 상기 연결관(40)의 내부에는 통과되는 냉각수에 와류가 발생되도록 하는 와류발생수단(45)이 구비되는데, 이 와류발생수단(45)으로는 연결관의 내주면을 따라 나선형으로 배열된 와류유도판이 적용되며, 이 외에도 냉각수의 흐름방향에 대해 소정각도 경사지도록 형성되어 냉각수에 와류가 발행되도록 하는 것은 모두 적용가능하다.In addition, the inside of the connecting pipe 40 is provided with a vortex generating means 45 for generating a vortex in the cooling water passing through, the vortex generating means 45 is arranged in a spiral along the inner circumferential surface of the connecting pipe The guide plate is applied, and in addition, it is possible to incline a predetermined angle with respect to the flow direction of the coolant so that any vortex is issued to the coolant.

상기 열교환관(50)은 알루미늄이나 구리 등의 열전도성이 우수한 재질로 이루어져 연료공급라인(35)에 연결되며 연결관(40)의 시트홈(41)을 따라 코일형태로 감겨져 설치된다. 이때, 상기 열교환관(50)은 그 양단부가 상기 연결관의 걸림돌기(44)에 걸려져 연결관(40)의 둘레면에 감겨진 상태를 유지하게 된다.The heat exchange tube 50 is made of a material having excellent thermal conductivity, such as aluminum or copper, is connected to the fuel supply line 35 and is wound and installed in a coil form along the seat groove 41 of the connection pipe 40. At this time, both ends of the heat exchange tube 50 are caught by the engaging protrusion 44 of the connecting tube to maintain a state wound around the circumferential surface of the connecting tube 40.

상기 열교환관(50)의 둘레면에는 우레탄 등의 보온성이 우수한 소재로 마감처리되어 열교환관(50)을 통과하는 연료가 외부의 공기에 의해 냉각되는 것을 방지하게 된다.The circumferential surface of the heat exchange tube 50 is finished with a material having excellent thermal insulation such as urethane to prevent the fuel passing through the heat exchange tube 50 from being cooled by outside air.

이상의 구성에 의한 연료 예열장치는 엔진(10)으로부터 라디에이터(20)로 전달되는 고온의 냉각수에 의해 엔진(10)에 공급되는 연료를 예열하여 공급하므로써, 연료의 활성화를 촉진시켜 연료의 연소율을 높이고, 엔진(10)의 출력을 증강시키게 된다. 이때, 상기 냉각수는 연결관(40) 내부의 와류발생수단(45)에 의해 연결관(40)과 고르게 접촉되면서 통과되기 때문에 열교환율이 더욱 증대된다. 또한, 상기 열교환관(50)을 통과하는 연료는 온도의 변화에 따른 팽창계수가 크기 때문에 예열되면서 그 부피가 증가되어 활성화의 촉진을 물론 연료의 절감효과를 가져오게 된다.The fuel preheater according to the above configuration preheats and supplies the fuel supplied to the engine 10 by the high temperature cooling water transmitted from the engine 10 to the radiator 20, thereby promoting the activation of the fuel and increasing the combustion rate of the fuel. The output of the engine 10 is enhanced. At this time, since the coolant passes through the contact pipe 40 evenly by the vortex generating means 45 inside the connection pipe 40, the heat exchange rate is further increased. In addition, the fuel passing through the heat exchange tube 50 has a large expansion coefficient due to the change in temperature, so that its volume increases as it is preheated, thereby promoting activation and saving fuel.

이상에서와 같이 본 고안에 의하면, 상기 연료 예열장치는 연료가 열교환관(50)을 통과하면서 예열되어 공급되므로, 연료의 활성화가 촉진되어 연소율이 높아지며, 엔진(10)의 출력이 증강되고, 예열에 따른 연료의 팽창에 의해 연료 절감효과를 가져올 수 있는 장점이 있다.As described above, according to the present invention, since the fuel preheater is preheated and supplied while the fuel passes through the heat exchange tube 50, the activation of the fuel is promoted, the combustion rate is increased, and the output of the engine 10 is enhanced, and the preheating is performed. There is an advantage that can lead to fuel savings by the expansion of the fuel.
