상기한 바와 같은 목적을 달성하기 위한 본 고안에 따른 연료 냉각장치는 리턴 파이프의 중간에 형성되는 냉각 케이스와, 상기 냉각 케이스내에 통과하는 연료가 일정량씩 고일 수 있도록 경사지며 상호 엇갈리게 설치된 다수의 냉각판으로 구성된 것을 특징으로 한다.Fuel cooling apparatus according to the present invention for achieving the above object is a cooling case formed in the middle of the return pipe, and a plurality of cooling plates are inclined and staggered mutually so that the fuel passing through the cooling case by a predetermined amount Characterized in that consisting of.

이하, 첨부된 도면을 참조하여 본 고안의 실시 예를 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention.

도 2는 본 고안에 따른 연료 냉각장치를 도시한 것으로서, 리턴 파이프(1)의 중간에 형성된 냉각 케이스(2)와, 상기 냉각 케이스(2)내에 통과하는 연료가 일정량씩 고일 수 있도록 경사지며 상호 엇갈리게 설치된 3개의 냉각판(3)으로 구성되어 있다.Figure 2 shows a fuel cooling apparatus according to the present invention, the cooling case 2 formed in the middle of the return pipe (1), and the fuel passing through the cooling case (2) is inclined so as to be a certain amount of high It consists of three cooling plates 3 alternately installed.

여기서, 상기 3개의 냉각판(3)을 경유하여 연료탱크(4)로 향하는 연료의 불순물을 여과할 수 있도록 상기 냉각 케이스(2)의 최하측에는 여과망(5)을 설치하였다.Here, a filtering net 5 is provided at the lowermost side of the cooling case 2 so as to filter impurities of the fuel directed to the fuel tank 4 via the three cooling plates 3.

물론, 상기 냉각 케이스(2)와 3개의 냉각판(3)은 열전도율이 좋은 재질로 형성하는 것이 유리하며, 본 고안에서는 구리(Cu)를 그 재질로 사용하고 있다.Of course, the cooling case 2 and the three cooling plates 3 are advantageously formed of a material having good thermal conductivity, and in the present invention, copper (Cu) is used as the material.

상기한 바와 같이 구성된 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

엔진의 작동에 따라 엔진 연소실에 연료가 지속적으로 공급되도록 연료펌프는 계속적으로 연료를 압송하며, 상기와 같이 압송된 연료의 일부는 인젝터를 통해 흡기 매니폴드로 유입되어 연소실로 공급되고, 상기와 같이 인젝터로 분사되지 못한 연료는 연료탱크로 회수된다.The fuel pump continuously pumps fuel so that fuel is continuously supplied to the engine combustion chamber according to the operation of the engine, and a portion of the fuel thus injected is introduced into the intake manifold through the injector and supplied to the combustion chamber. Fuel not injected into the injector is returned to the fuel tank.

이때, 연료는 압력레귤레이터와 리턴 파이프(1)를 경유하여 연료탱크(4)로 회수되는 바, 상기 리턴 파이프(1)에 설치된 냉각 케이스(2)를 경유하면서 엔진 근처에서 전달받은 열을 방출하게 된다.At this time, the fuel is recovered to the fuel tank 4 via the pressure regulator and the return pipe (1), so as to discharge the heat received near the engine while passing through the cooling case (2) installed in the return pipe (1). do.

즉, 상기 리턴 파이프(1)를 통해 냉각 케이스(2)로 유입되는 연료는 상기 3개의 냉각판(3)에 의해 즉각적으로 냉각 케이스(2)를 통과하지 못하고 가장 위쪽의 냉각판(3)으로부터 하측으로 차례로 이동하게 되는 바, 상기와 같은 연료의 이동중 각 냉각판(3)에는 일정량의 연료가 잔류하면서 열을 냉각판(3)과 냉각케이스(2)를 통해 외부로 방출될 수 있도록 하는 것이다.That is, the fuel flowing into the cooling case 2 through the return pipe 1 does not immediately pass through the cooling case 2 by the three cooling plates 3, but from the uppermost cooling plate 3. In order to move downward in order to allow the fuel to be discharged to the outside through the cooling plate 3 and the cooling case 2 while a certain amount of fuel remains in each cooling plate (3) during the movement of the fuel as described above. .

물론, 상기와 같이 3개의 냉각판(3)을 경유하면서 냉각된 연료는 상기 냉각케이스(2)의 최하측에 설치된 여과망(5)을 통과하면서 불순물이 여과되어 깨끗하고 낮은 온도상태로 연료탱크(4)로 회수되게 된다.Of course, the fuel cooled while passing through the three cooling plates 3 as described above passes through the filter network 5 installed at the lowermost side of the cooling case 2, and impurities are filtered to clean and cool the fuel tank ( 4) will be recovered.

따라서, 상기와 같이 연료탱크(4)로 회수되는 연료의 온도를 효과적으로 냉각시킬 수 있도록 함으로써, 연료탱크(4) 내의 연료온도 상승을 억제하여 연료의 증발에 의해 발생되는 배기가스를 저감하고, 연료내의 기포발생을 억제하여 베이퍼록 현상을 방지함으로써 안정된 연료공급상태를 확보할 수 있도록 하는 효과가 있다.Therefore, by effectively cooling the temperature of the fuel recovered to the fuel tank 4 as described above, the rise of the fuel temperature in the fuel tank 4 is suppressed to reduce the exhaust gas generated by the evaporation of the fuel, and the fuel It is possible to secure a stable fuel supply state by suppressing the bubble generation in the inside to prevent the vapor lock phenomenon.
