라디에이터용 냉각핀 구조{COOLING FIN STRUCTURE FOR RADIATOR}Cooling fin structure for radiator {COOLING FIN STRUCTURE FOR RADIATOR}

본 발명은 라디에이터에 관한 것으로 특히, 공기의 흐름이 효율적으로 이동될 수 있는 구조를 가지면서 냉각효과가 상승되는 라디에이터용 냉각핀 구조에 관한 것이다.The present invention relates to a radiator, and more particularly, to a radiator cooling fin structure in which a cooling effect is increased while having a structure in which air flow can be efficiently moved.

통상적으로, 자동차 등의 엔진에는 냉각장치가 구비되어 실린더 내의 연소가스 온도에 의해서 실린더, 실린더헤드, 피스톤 등에 흡수되는 열을 차단하여 변형을 방지함과 동시에 엔진의 출력이 감소되는 것을 방지하게 된다. 이와 같은 냉각장치로는 수냉식과 공냉식을 가지게 되며 본 발명에서는 수냉식에 사용되는 라디에이터에 관한 것으로서, 상기 라디에이터는 순환펌프에 의해 냉각수가 강제 순환되면서 엔진을 냉각시키게 된다.In general, an engine such as an automobile is provided with a cooling device to block heat absorbed by the cylinder, cylinder head, piston, etc. by the combustion gas temperature in the cylinder to prevent deformation and at the same time prevent the output of the engine from being reduced. Such a cooling device has a water-cooled and air-cooled type and relates to a radiator used in the water-cooled type in which the radiator cools the engine while forcedly circulating the cooling water by a circulation pump.

이와 같은 라디에이터는, 엔진과 연결되는 급수관과 배수관을 가지는 양측의 탱크를 가지고 있으며, 상기 양측 탱크 사이를 연결하는 튜브가 소정을 간격으로 배치되어 고정된다. 그리고 상기 각 튜브 사이에는 알루미늄으로 된 박판의 냉각핀이 장착되어 있다. 그러나 위와 같은 종래의 냉각핀은 구조상으로 효율적인 냉각이 되지 못하고 있으며 내구성이 취약한 문제점을 가지고 있다. 즉, 지그재그식으로 밴딩되어 있는 냉각핀의 각 측면에 다수의 구멍으로 형성된 에어통로가 형성되는데, 상기 에어통로는 모두 동일한 방향으로 향하는 경사를 가진다. 따라서, 상기 에어통로를 통과하는 공기는 일측방향의 경사를 따라 신속하게 배출되면서 라디에이터에 머무르는 시간이 짧아 튜브의 냉각효과가 떨어질 수밖에 없다. 그리고 도 6에서와 같이 냉각핀(20')의 밴딩부분은 곡면 즉, 반원형으로 되어 탱크(12')의 측면으로 용접되는데 이는 접촉면적이 적어 열의 전도율이 미세하고 이 역시 냉각효율이 상승되지 못하는 원인이 된다. 또한, 상기 곡면부에는 협소한 틈새(21)가 형성되면서 그 틈새 사이로 먼지 등의 이물질이 끼이게 되고 세균이 서식할 수 있으며, 이는 청소로서도 제거가 잘 되지 않는다.Such a radiator has tanks on both sides having a water supply pipe and a drain pipe connected to an engine, and tubes connecting the both tanks are arranged and fixed at predetermined intervals. And between each tube is mounted a thin plate of cooling fin made of aluminum. However, the conventional cooling fins as described above do not have efficient cooling due to the structure and have a weak durability. That is, air passages formed of a plurality of holes are formed on each side of the cooling fins that are zigzag-banded, and all of the air passages have inclinations facing the same direction. Therefore, the air passing through the air passage is quickly discharged along the inclination in one direction, so that the time to stay in the radiator is short, the cooling effect of the tube is inevitably deteriorated. As shown in FIG. 6, the bending portion of the cooling fin 20 ′ is curved, that is, semi-circular, and welded to the side of the tank 12 ′, which has a small contact area, so that thermal conductivity is fine and cooling efficiency is not increased. Cause. In addition, as the narrow gap 21 is formed in the curved portion, foreign substances such as dust are caught between the gaps, and bacteria may inhabit, which is not easily removed even by cleaning.

본 발명은 상술한 종래의 문제점을 극복하기 위한 것으로 본 발명의 목적은, 냉각효과를 상승시킬 수 있고, 용접부분에 이물질이 끼이거나 세균이 서식할 수 있는 것을 미연에 방지할 수 있는 라디에이터용 냉각핀 구조를 제공함에 있다.The present invention is to overcome the above-mentioned conventional problems, an object of the present invention, it is possible to increase the cooling effect, cooling for the radiator that can prevent the foreign matter caught in the weld portion or the bacteria can live in advance. In providing a fin structure.

상기의 목적을 달성하기 위해 본 발명은, 양측의 탱크(12) 사이로 일정한 간격을 두고 소정의 튜브(18)가 연결되어 있고, 상기 튜브 사이에 냉각핀(20)이 설치되는 라디에이터에 있어서, 상기 냉각핀(20)은 지그재그 연속적으로 밴딩될 때 상기 밴딩부분은 수직으로 형성되면서 평면의 접합부(22)를 구비하게 되고, 측면부에 형성되는 에어통로(26)는 일정한 간격을 두고 동일한 방향으로 경사를 두고 있으나, 소정이 길이로 구획되면서 서로 그 방향을 달리하고 있음을 특징으로 한다.In order to achieve the above object, the present invention is a radiator in which a predetermined tube 18 is connected at regular intervals between the tanks 12 on both sides, and a cooling fin 20 is installed between the tubes. When the cooling fins 20 are continuously zigzag, the bending portions are vertically formed and have a flat joint portion 22, and the air passages 26 formed on the side portions are inclined in the same direction at regular intervals. However, it is characterized in that the direction is different from each other while being divided into a predetermined length.

According to the drawing, the radiator main body 10 is provided with a tank 12 on both sides, while one side of the water supply pipe 14 is connected to the other side of the drain pipe 14, the cooling water to cool the engine by an external circulation pump Continuous circulation in the tank. In addition, a plurality of tubes 18 are connected between the tanks 12 at both sides to move the cooling water inside the tanks at a predetermined interval, and the cooling fins 20 assembled between the tubes 18 are transferred to the tubes. Will heat the outside.

그리고, 도 3 내지 도 5는 본 발명에 따라서 라디에이터에 조립되는 냉각핀(20)의 구조를 도시하고 있다. 도면에 따르면, 상기 냉각핀(20)은 양측의 탱크(12)와 가로방향의 튜브(18) 사이에 조립되는 것으로 최대한의 냉각효율 가지기 위해 연속적으로 밴딩되면서 지그재그식으로 형성된다.3 to 5 show the structure of the cooling fins 20 assembled to the radiator according to the present invention. According to the drawings, the cooling fins 20 are assembled between the tank 12 on both sides and the tube 18 in the transverse direction and are formed in a zigzag manner while being continuously bent to have the maximum cooling efficiency.

위를 더욱 자세하게 설명하면 다음과 같다.The above is described in more detail as follows.

양측의 탱크(12)에는 각각 급수관(14)과 배수관(16)을 가지고 있고, 상기 급수관(14)과 엔진(도면에 미도시) 사이에는 순환펌프(도면에 미도시)가 장착되면서 엔진을 냉각시킨 냉각수를 상기 탱크(12) 내부로 유입시킨다. 그리고 양측의 탱크 사이에는 일정한 간격을 두고 소정의 튜브(18)가 연결되어 있으며, 상기 냉각수가 튜브(18)를 통해 이동하게 되면서 냉각된다. 한편 상기 튜브(18) 사이에는 지그재그식으로 벤딩되어 있는 냉각핀(20)이 용접으로 부착되어 있다. 즉, 상기 냉각핀(20)은 알루미늄의 박판으로서 연속적인 "ㄹ" 형상이 되도록 밴딩되어 있다. 이때 상기 밴딩부는 곡선을 두지 않고 수직으로 형성되면서 도 3에서와 같이 전방에서 평면적인 접합부(22)를 형성하게 된다. 이후, 상기 접합부(22)는 도 5에서와 같이 상/하의 튜브(18)와 전체면이 접촉되어 용접으로 부착된다.The tank 12 on each side has a water supply pipe 14 and a drain pipe 16, respectively, and the engine is cooled while a circulation pump (not shown) is mounted between the water supply pipe 14 and the engine (not shown). The cooled water is introduced into the tank 12. And a predetermined tube 18 is connected at regular intervals between the tanks on both sides, and the coolant is cooled as it moves through the tube 18. Meanwhile, between the tubes 18, a cooling fin 20 which is bent in a zigzag manner is attached by welding. That is, the cooling fins 20 are bent to form a continuous " d " shape as a thin sheet of aluminum. At this time, the bending portion is formed vertically without a curve to form a planar joint 22 in the front as shown in FIG. Thereafter, the joint 22 is attached to the upper and lower tubes 18 and the whole surface by welding as shown in FIG.

그리고, 상기 냉각핀(20)의 각 측면부(24)에는 일정한 간격을 두고 절개와 함께 밴딩되면서 소정의 각도로 비틀어져 있는 에어통로(26)를 두고 있다. 이때, 상기 에어통로(26)는 일정한 간격을 두고 동일한 방향으로 경사를 두고 있으나, 도 4에서와 같이 소정이 길이로 구획되면서 서로 그 경사방향을 달리하고 있다.Each side portion 24 of the cooling fin 20 has an air passage 26 that is bent at a predetermined angle while being bent with an incision at regular intervals. At this time, the air passages 26 are inclined in the same direction at regular intervals, but as shown in FIG.

이와 같이 구성되는 본 발명은 다음과 같이 작동하게 된다.The present invention configured as described above operates as follows.

먼저, 급수관(14)을 가진 일측의 탱크(12) 내부로 투입되는 냉각수는 각 튜브(18)를 통해 타측의 탱크 내부로 이동하게 되며, 튜브로 이동하는 과정에서 상기 냉각수는 튜브 및 냉각핀과 열교환이 이루어지게 되면서 냉각된다. 이때 상기 냉각핀(20)의 전방에서 후방으로 이동되는 공기는 도 4에서와 같이 방향을 달리하는 에어통로(26)에 의해서 직선적으로 통과하지 않고, 지그재그식으로 이동하게 됨에 따라 상기 공기는 라디에이터에서 머무르는 시간을 지연되면서 냉각효과를 높이게 된다. 이와 같이 냉각된 냉각수는 타측의 탱크(12)로 이동된 뒤 배수관(16)을 통해 엔진으로 복귀하게 되고 계속적으로 냉각작업을 수행하게 된다.First, the coolant introduced into the tank 12 on one side with the water supply pipe 14 is moved into the tank on the other side through each tube 18, and in the process of moving to the tube, the coolant is connected to the tube and the cooling fins. As the heat exchange takes place, it is cooled. At this time, the air moved from the front to the rear of the cooling fins 20 does not pass linearly by the air passages 26 which are different in directions as shown in FIG. 4, and thus the air moves in a zigzag manner. This delays the stay time and increases the cooling effect. The coolant thus cooled is returned to the engine through the drain pipe 16 after being moved to the tank 12 on the other side and continuously performing the cooling operation.

이상으로 살펴본 바와 같이, 본 발명에 따른 라디에이터용 냉각핀 구조는 탱크와의 접합부가 평면적으로서 접촉부가 커지게 되어 냉각효과가 상승되며, 냉각핀 사이를 통과하는 공기는 와류현상이 발생되어 냉각핀에 전도된 고열을 효율적으로 냉각시킬 수 있으며, 용접부분에는 양측으로 틈새를 두지 않아 이물질이 끼이거나 세균이 서식할 수 있는 것을 미연에 방지할 수 있는 효과를 가진다.As described above, the radiator cooling fin structure according to the present invention has a contact portion with the tank in a planar contact portion to increase the cooling effect, the air passing between the cooling fins is a vortex phenomenon occurs in the cooling fins It can efficiently cool the conducted high heat, and there is no gap on both sides of the welded part, so that foreign matters can be caught or bacteria can inhabit.
