도 2 내지 도 5를 참조하면, 상기 방열 핀(140)은 핀 본체(141), 복수의 튜브 삽입공(143) 및 접합 증대부(145)를 포함할 수 있다. 또한, 상기 방열 핀(140)은 복수의 루버(147) 및/또는 탭(149)을 더 포함할 수도 있다.2 to 5, the heat dissipation fin 140 may include a fin body 141, a plurality of tube insertion holes 143, and a joint augmentation part 145. In addition, the heat dissipation fin 140 may further include a plurality of louvers 147 and/or tabs 149.
상기 핀 본체(141)는 판상, 즉 평평한 플레이트 형상으로 이루어질 수 있다.The pin body 141 may be formed in a plate shape, that is, a flat plate shape.
상기 튜브 삽입공(143)은 핀 본체(141)의 일면과 타면을 관통하도록 형성될 수 있다.The tube insertion hole 143 may be formed to penetrate one surface and the other surface of the pin body 141.
그리고, 상기 튜브 삽입공(143)에는 튜브(130)가 삽입될 수 있다.In addition, the tube 130 may be inserted into the tube insertion hole 143.
상기 튜브 삽입공(143)은 튜브(130)에 대응되는 형상으로 형성될 수 있다. 예컨데, 상기 튜브 삽입공(143)은 튜브(130)의 단면 형상에 상응하는 형상을 가질 수 있다. 따라서, 상기 튜브 삽입공(143)의 형상에 대한 이하의 설명은 튜브(130)의 단면 형상에도 동일하게 또는 일부 변경을 가하여 그대로 적용될 수 있다.The tube insertion hole 143 may be formed in a shape corresponding to the tube 130. For example, the tube insertion hole 143 may have a shape corresponding to the cross-sectional shape of the tube 130. Therefore, the following description of the shape of the tube insertion hole 143 may be applied as it is to the cross-sectional shape of the tube 130 by applying the same or some changes.
상기 튜브 삽입공(143)은 서로 마주보는 한 쌍의 원호부(143a), 및 한 쌍의 원호부(143a)를 연결하고 서로 마주보게 배치되는 한 쌍의 연결부(143b)를 포함할 수 있다.The tube insertion hole 143 may include a pair of arc portions 143a facing each other, and a pair of arc portions 143b connecting the pair of arc portions 143a and disposed to face each other.

In particular, the connection portion 143b may be formed of one concave curvature portion to increase the contact area between the tube 130 and the heat dissipation fin 140. Here, the interval W1 between the arc portions 143a may be referred to as a first interval. In addition, the gap W2 between the connecting portions 143b may be referred to as a second gap.
또한, 상기 연결부(143b)의 곡률부는 호 형상으로 형성될 수 있다. 그리고, 상기 루버(147)의 배치를 고려하여 상기 연결부(143b)의 중앙측에 최단거리가 형성되도록 상기 곡률부가 배치될 수 있다. 그에 따라, 상기 연결부(143b) 사이의 간격(W2)은 중앙측에서 최단거리가 될 수 있다. In addition, the curvature portion of the connecting portion 143b may be formed in an arc shape. Then, in consideration of the arrangement of the louver 147, the curvature portion may be arranged such that the shortest distance is formed at the center side of the connection portion 143b. Accordingly, the distance W2 between the connecting portions 143b may be the shortest distance from the central side.
복수의 튜브 삽입공(143)은 핀 본체(141)의 길이 방향으로 상호간에 이격하여 배치될 수 있다. 따라서, 복수의 튜브(130)의 각각은 복수의 튜브 삽입공(143) 각각에 삽입될 수 있다.The plurality of tube insertion holes 143 may be disposed spaced apart from each other in the longitudinal direction of the pin body 141.

Accordingly, the junction increasing portion 145 may be formed along the edge of the tube insertion hole 143.
따라서, 접합 증대부(145)는 튜브 삽입공(143)을 감싸도록 핀 본체(141)의 일면에서 돌출된 형태일 수 있다. 여기서, 접합 증대부(145)는 중공의 기둥 형상일 수 있지만, 반드시 이에 한정되는 것은 아니다.Therefore, the bonding augmentation part 145 may have a shape protruding from one surface of the pin body 141 so as to surround the tube insertion hole 143. Here, the junction increasing portion 145 may be a hollow pillar shape, but is not limited thereto.
도 5을 참조하면, 상기 접합 증대부(145)는 핀 본체(141)에서 절곡되어 형성될 수 있기 때문에, 상기 튜브 삽입공(143)에 삽입되는 튜브(130)와 마주보게 배치될 수 있다. 따라서, 상기 접합 증대부(145)에 의해 튜브(130)와 방열 핀(140) 사이의 접촉 면적이 증가할 수 있다.Referring to FIG. 5, since the junction augmentation part 145 may be formed by bending at the pin body 141, it may be disposed to face the tube 130 inserted into the tube insertion hole 143. Therefore, the contact area between the tube 130 and the heat dissipation fin 140 may be increased by the junction increasing unit 145.
한편, 상기 접합 증대부(145)의 내측면에는 클래드 층(미도시)이 형성될 수 있다. 상기 클래드 층은 납(Pb)을 포함할 수 있지만, 반드시 이에 한정되는 것은 아니고, 상기 튜브(130)와 방열 핀(140)의 브레이징 재로 사용될 수 있는 것이라면 다른 재료를 포함할 수도 있다.Meanwhile, a cladding layer (not shown) may be formed on the inner surface of the junction increasing portion 145. The clad layer may include lead (Pb), but is not limited thereto, and may include other materials as long as it can be used as a brazing material for the tube 130 and the heat dissipation fin 140.
도 2 내지 도 4를 참조하면, 복수의 튜브 삽입공(143) 사이에는 복수의 루버(147)가 배치될 수 있다. 여기서, 상기 루버(147)는 루버 핀이라 불릴 수 있다. 2 to 4, a plurality of louvers 147 may be disposed between the plurality of tube insertion holes 143. Here, the louver 147 may be referred to as a louver pin.
상기 루버(147)는 핀 본체(141)가 절개 및 절곡되어 형성될 수 있다. 그리고, 상기 루버(147)는 핀 본체(141)에 대해 경사지게 배치될 수 있다. 그리고, 상기 루버(147)는 핀 본체(141)의 일면과 타면 간에 공기가 원활하게 유동할 수 있도록 복수 개가 상호 이격되게 핀 본체(141)에 배치될 수 있다. 그에 따라, 폭 방향을 따라 배치되는 상기 루버(147) 사이에 공기가 이동할 수 있는 통로가 형성될 수 있기 때문에, 상기 루버(147)는 열교환 효율을 향상시킬 수 있다.The louver 147 may be formed by cutting and bending the pin body 141. In addition, the louver 147 may be disposed to be inclined with respect to the pin body 141. In addition, a plurality of the louvers 147 may be disposed on the pin body 141 to be spaced apart from each other so that air can flow smoothly between one surface and the other surface of the pin body 141. Accordingly, since a passage through which air can move may be formed between the louvers 147 disposed along the width direction, the louver 147 may improve heat exchange efficiency.
도 6은 도 4의 B부분의 사시도로서, 루버(147)의 다른 배치예를 나타낼 수 있다. 6 is a perspective view of part B of FIG. 4, and may show another example of the arrangement of the louver 147.
도 6을 참조하면, 상기 루버(147)는 루버(147)의 경사면을 따라 연장되는 복수의 골부(147a)를 포함할 수 있다. 예를 들어, 상기 루버(147)는 폭 방향으로 톱니 또는 물결 모양의 단면 형상으로 형성될 수 있다. 그에 따라, 상기 루버(147)는 공기와의 접촉 면적이 증가할 수 있다.Referring to FIG. 6, the louver 147 may include a plurality of valleys 147a extending along an inclined surface of the louver 147. For example, the louver 147 may be formed in a cross-sectional shape of a tooth or a wavy shape in the width direction. Accordingly, the louver 147 may increase the contact area with the air.
그리고, 도 6에 도시된 바와 같이, 상기 루버(147)를 향해 유입되는 공기의 흐름을 고려하여, 복수 개의 루버(147)는 서로 다른 방향을 향해 배치될 수 있다. 예컨데, 복수 개의 루버(147)는 'V'자 형상으로 핀 본체(141)에 배치될 수 있다. And, as shown in Figure 6, in consideration of the flow of air flowing toward the louver 147, a plurality of louvers 147 may be arranged in different directions. For example, the plurality of louvers 147 may be disposed on the pin body 141 in a'V' shape.
상기 탭(149)은 핀 본체(141)의 일면에서 돌출되게 복수 개가 형성될 수 있다. A plurality of tabs 149 may be formed to protrude from one surface of the pin body 141.
상기 탭(149)이 핀 본체(141)를 기준으로 돌출되게 형성됨에 따라, 상기 탭(149)은 상기 방열 핀(140) 사이의 거리를 유지시킬 수 있다. 여기서, 상기 탭(149)의 돌출 높이는 상기 접합 증대부(145)의 돌출 높이보다 클 수 있다. 이때, 상기 탭(149)과 상기 접합 증대부(145)는 동일한 방향으로 핀 본체(141)에서 돌출되게 형성될 수 있다.As the tab 149 is formed to protrude based on the pin body 141, the tab 149 may maintain a distance between the heat dissipation fins 140. Here, the protruding height of the tab 149 may be greater than the protruding height of the junction increasing portion 145. At this time, the tab 149 and the junction increasing portion 145 may be formed to protrude from the pin body 141 in the same direction.
예컨데, 상기 방열 핀(140) 중 어느 하나에 배치되는 탭(149)의 단부는 상기 삽입 방향으로 이웃하게 배치되는 방열 핀(140)의 핀 본체(141)의 일면에 접촉되게 배치되어 지지할 수 있기 때문에, 상기 방열 핀(140) 사이의 거리를 유지시킬 수 있다. 그에 따라, 상기 탭(149)에 의해 FPDM(Fins Per DeciMeter, 10cm당 핀의 개수)이 유지될 수 있지만, 그 결과 루버(147)의 설치 공간이 줄어들 수 있다.For example, an end of the tab 149 disposed in any one of the heat dissipation fins 140 may be disposed and supported in contact with one surface of the fin body 141 of the heat dissipation fin 140 disposed adjacent to the insertion direction. Therefore, the distance between the heat dissipation fins 140 can be maintained. Accordingly, FPDM (Fins Per DeciMeter, number of pins per 10 cm) may be maintained by the tab 149, but as a result, the installation space of the louver 147 may be reduced.
또한, 상기 탭(149)은 핀 본체(141)의 일 영역을 절개 및 절곡하여 형성할 수 있다. 그에 따라, 핀 본체(141)에는 일면과 타면을 관통하도록 홀이 형성될 수 있으며, 상기 홀을 통해 공기가 이동할 수 있다. In addition, the tab 149 may be formed by cutting and bending an area of the pin body 141. Accordingly, a hole may be formed in the pin body 141 to penetrate one surface and the other surface, and air may move through the hole.
도 7은 도 4의 변형예로서, 방열 핀(140)의 다른 실시예를 나타낼 수 있다.7 is a modified example of FIG. 4, and may show another embodiment of the heat dissipation fin 140.
도 7을 참조하면, 상기 튜브 삽입공(143)은 서로 마주보는 한 쌍의 원호부(143a), 및 한 쌍의 원호부(143a)를 연결하고 서로 마주보는 한 쌍의 연결부(143b)를 포함할 수 있고, 연결부(143b)는 2개의 오목한 곡률부로 이루어져 튜브(130)와 방열 핀(140) 사이의 접촉 면적을 더욱 증가시킬 수 있다.Referring to FIG. 7, the tube insertion hole 143 includes a pair of arc portions 143a facing each other, and a pair of arc portions 143a connecting the pair of arc portions 143a and facing each other. The connecting portion 143b may be formed of two concave curvature portions to further increase the contact area between the tube 130 and the heat dissipation fin 140.
여기서, 상기 곡률부는 호 형상으로 형성될 수 있으며, 상기 연결부(143b)의 중앙측에 최장거리가 형성되도록 두 개의 상기 곡률부가 상기 연결부(143b)에 배치될 수 있다. 그에 따라, 상기 연결부(143b) 사이의 간격(W2)은 중앙측에서 최장거리가 될 수 있다. Here, the curvature portion may be formed in an arc shape, and the two curvature portions may be disposed on the connection portion 143b so that the longest distance is formed at the center side of the connection portion 143b. Accordingly, the distance W2 between the connecting portions 143b may be the longest distance from the central side.
도 8은 도 4의 변형예로서, 방열 핀(140)의 또 다른 실시예를 나타낼 수 있다.8 is a modified example of FIG. 4, and may show another embodiment of the heat dissipation fin 140.
도 8을 참조하면, 상기 방열 핀(140)은 루버(147)의 폭 방향측에 하나의 탭(149)이 배치되게 형성될 수 있다. 도 8에 도시된 바와 같이, 하나의 루버(147)를 기준으로 폭 방향측에 하나의 탭(149)이 배치될 수 있다. Referring to FIG. 8, the heat dissipation fin 140 may be formed such that one tab 149 is disposed on the width direction side of the louver 147. As illustrated in FIG. 8, one tab 149 may be disposed on the width direction side based on one louver 147.
여기서, 상기 방열 핀(140)의 길이 방향을 기준으로 상기 탭(149)은 지그재그 형상으로 배치될 수 있다. 그에 따라, 지그재그 배치를 갖는 복수 개의 탭(149)은 균형있게 방열 핀(140) 사이의 거리를 유지하면서도 상기 방열 핀(140)을 지지할 수 있다. Here, the tab 149 may be arranged in a zigzag shape based on the longitudinal direction of the heat dissipation fin 140. Accordingly, the plurality of tabs 149 having a zigzag arrangement can support the heat dissipation fin 140 while maintaining the distance between the heat dissipation fins 140 in a balanced manner.
도 4에 도시된 방열 핀(140)과 도 8에 도시된 방열 핀(140)을 비교해 볼 때, 도 8에 도시된 방열 핀(140)은 도 4에 도시된 방열 핀(140)보다 탭(149)의 갯수가 적다는 점에 차이가 있다. 그에 따라, 상기 탭(149)이 형성되었던 핀 본체(141)의 영역에도 루버(147)가 배치될 수 있기 때문에, 루버(147)의 설치 공간을 증대시킴으로써, 열교환 효율을 향상시킬 수 있다. When comparing the heat dissipation fin 140 shown in FIG. 4 and the heat dissipation fin 140 shown in FIG. 8, the heat dissipation fin 140 shown in FIG. 8 is more tabbed than the heat dissipation fin 140 shown in FIG. 4 149) is small in number. Accordingly, since the louver 147 may be disposed in the region of the pin body 141 on which the tab 149 is formed, the heat exchange efficiency can be improved by increasing the installation space of the louver 147.
도 9는 도 4의 변형예로서, 방열 핀(140)의 또 다른 실시예를 나타낼 수 있다.9 is a modified example of FIG. 4, and may show another embodiment of the heat dissipation fin 140.
상기 접합 증대부(145)가 핀 본체(141)를 기준으로 돌출되게 형성됨에 따라, 상기 접합 증대부(145)는 상기 방열 핀(140) 사이의 거리를 유지시키는 기능을 수행할 수 있다. As the junction augmentation part 145 is formed to protrude based on the pin body 141, the junction augmentation part 145 may function to maintain a distance between the heat dissipation fins 140.
예컨데, 상기 방열 핀(140) 중 어느 하나에 배치되는 접합 증대부(145)의 단부는 상기 삽입 방향으로 이웃하게 배치되는 방열 핀(140)의 핀 본체(141)의 일면에 접촉되어 지지할 수 있기 때문에, 상기 방열 핀(140) 사이의 거리를 유지시킬 수 있다. 다만, 상기 튜브(130)는 방열 핀(140)의 튜브 삽입공(143)에 삽입되는 방식으로 결합된 후 열에 의해 확관될 수 있는바, 이러한 결합 방식 및 상기 열에 의한 영향을 고려하여 방열 핀(140)의 재질이 결정될 수 있다. For example, the end portion of the junction increasing portion 145 disposed in any one of the heat dissipation fins 140 may be in contact with and supported by one surface of the fin body 141 of the heat dissipation fins 140 disposed adjacent to the insertion direction. Therefore, the distance between the heat dissipation fins 140 can be maintained. However, the tube 130 can be expanded by heat after being combined in a manner that is inserted into the tube insertion hole 143 of the heat dissipation fin 140, so that the heat dissipation fin ( 140) may be determined.
따라서, 상기 접합 증대부(145)는 FPDM(Fins Per DeciMeter, 10cm당 핀의 개수)이 유지하면서도, 루버(147)의 설치 공간을 증대시킬 수 있다. Accordingly, the junction increase unit 145 may increase the installation space of the louver 147 while maintaining the FPDM (Fins Per DeciMeter, the number of pins per 10 cm).
도 9를 참조하면, 방열 핀(140)은 상기 방열 핀(140)은 핀 본체(141), 복수의 튜브 삽입공(143), 접합 증대부(145) 및 복수의 루버(147)를 포함할 수 있다.Referring to FIG. 9, the heat dissipation fin 140 may include the fin body 141, a plurality of tube insertion holes 143, a joint augmentation part 145, and a plurality of louvers 147. have.
도 4에 도시된 방열 핀(140)과 도 9에 도시된 방열 핀(140)을 비교해 볼 때, 도 9에 도시된 방열 핀(140)은 탭(149)을 포함하지 않는다는 점 및 접합 증대부(145)의 단부가 핀 본체(141)를 지지한다는 점에 차이가 있다. 그에 따라, 상기 탭(149)이 형성되었던 핀 본체(141)의 영역에도 루버(147)가 배치될 수 있기 때문에, 루버(147)의 설치 공간을 증대시킴으로써, 상기 방열 핀(140)의 열교환 효율을 향상시킬 수 있다. When comparing the heat dissipation fin 140 shown in FIG. 4 and the heat dissipation fin 140 shown in FIG. 9, the heat dissipation fin 140 shown in FIG. 9 does not include the tab 149 and the junction augmentation part ( The difference is that the end of 145 supports the pin body 141. Accordingly, since the louver 147 may be arranged in the region of the pin body 141 on which the tab 149 is formed, by increasing the installation space of the louver 147, the heat exchange efficiency of the heat dissipation fin 140 is increased. Improve it.
도 10은 종래의 기계식 라디에이터의 튜브와 방열 핀의 결합을 나타내는 도면이다. 10 is a view showing the coupling of the tube and the heat dissipation fin of a conventional mechanical radiator.
도 10을 참조하면, 종래의 라디에이터의 튜브(10)와 방열 핀(20)은 튜브(10)의 내경보다 큰 외경을 갖는 종래의 확관부(30)에 의해 기계적으로 결합될 수 있다. 예컨데, 상기 확관부(30)가 튜브(10)의 내부로 삽입되는 과정에서 상기 튜브(10)의 내경 및 외경이 증가하면서 확관 작업이 이루어질 수 있다. 그에 따라, 상기 튜브(10)의 외주면은 방열 핀(20)과 접촉하게 된다.Referring to FIG. 10, the tube 10 and the radiating fin 20 of the conventional radiator may be mechanically coupled by a conventional dilator 30 having an outer diameter larger than the inner diameter of the tube 10. For example, as the inner diameter and the outer diameter of the tube 10 increase while the tube 30 is inserted into the tube 10, the tube expansion operation may be performed. Accordingly, the outer peripheral surface of the tube 10 comes into contact with the heat dissipation fin 20.
그러나, 이러한 기계적 결합은 결합력이 낮아 충격에 의해 상기 결합이 해제되는 문제가 있다. 또한, 상기 기계적 결합은 단순 접촉을 유도하기 때문에, 열교환 효율이 떨어지는 문제가 있다. However, this mechanical coupling has a problem that the coupling strength is low and the coupling is released by impact. In addition, since the mechanical coupling induces simple contact, there is a problem in that heat exchange efficiency is poor.
도 11은 실시예에 따른 열교환기의 제조장치를 나타내는 도면이고, 도 12는 실시예에 따른 열교환기의 제조장치를 이용하여 종래의 기계식 라디에이터의 튜브와 방열 핀의 결합을 나타내는 도면이고, 도 13은 실시예에 따른 열교환기의 제조장치에 의해 제조된 실시예에 따른 열교환기의 튜브와 방열 핀의 결합 관계를 나타내는 도면이다.11 is a view showing an apparatus for manufacturing a heat exchanger according to an embodiment, and FIG. 12 is a view showing a combination of a heat radiating fin and a tube of a conventional mechanical radiator using the apparatus for manufacturing a heat exchanger according to an embodiment.

상기 확관부(210)는 튜브(130)의 내경보다 큰 외경을 가질 수 있다. 따라서, 확관부(210)가 튜브(130) 내에 삽입되는 과정에서 튜브(130)의 내경 및 외경이 증가하면서 확관 작업이 이루어질 수 있다. 또한, 튜브(130)의 확관 작업은 튜브(130)가 방열 핀(140)의 튜브 삽입공(143)에 삽입된 상태에서 이루어지므로, 튜브(130)는 확관 작업에 의해 방열 핀(140)에 단단히 고정될 수 있다. The expansion tube 210 may have an outer diameter larger than the inner diameter of the tube 130. Therefore, in the process in which the expansion portion 210 is inserted into the tube 130, the expansion and expansion of the inner diameter and the outer diameter of the tube 130 may be performed. In addition, since the expansion operation of the tube 130 is performed while the tube 130 is inserted into the tube insertion hole 143 of the heat dissipation fin 140, the tube 130 is attached to the heat dissipation fin 140 by the expansion operation. It can be fixed securely.
이때, 실시예에 따른 열교환기의 방열 핀(140)은 상기 접합 증대부(145)를 포함하고 있기 때문에, 상기 확관부(210)를 이용한 확관 작업시, 상기 접합 증대부(145)에 의한 면접촉을 할 수 있다. 그에 따라, 실시예에 따른 열교환기의 방열 핀(140)과 튜브(130)의 결합력 및 열교환 효율은 증대될 수 있다. At this time, since the heat dissipation fin 140 of the heat exchanger according to the embodiment includes the junction augmentation part 145, during the expansion operation using the augmentation part 210, surface contact by the junction augmentation part 145 is performed. can do. Accordingly, the coupling force and heat exchange efficiency of the heat dissipation fin 140 and the tube 130 of the heat exchanger according to the embodiment may be increased.
상기 가열부(220)는 확관부(210)를 가열할 수 있다. 따라서, 확관부(210)는 튜브(130)를 확관함과 동시에 튜브(130) 또는 방열 핀(140) 상에 형성된 클래드 층(미도시)을 녹여 튜브(130)와 방열 핀(140)을 연결하는 접합 증대부(230)를 형성할 수 있다. 여기서, 상기 가열부(220)는 확관부(210) 내에 배치되는 전기 히터를 포함할 수 있으나 반드시 이에 한정되는 것은 아니고, 가열부(220)는 다양한 형태의 공지된 히터를 포함할 수도 있다. 이때, 상기 클래드 층을 녹아 형성되는 접합 증대부(230)는 제2 접합 증대부라 불릴 수 있다. 그에 따라, 실시예에 따른 열교환기에 배치되는 방열 핀(140)의 접합 증대부(145)는 제1 접합 증대부라 불릴 수 있다. The heating unit 220 may heat the expansion tube 210. Therefore, the expansion pipe 210 expands the tube 130 and simultaneously melts the clad layer (not shown) formed on the tube 130 or the heat radiation fin 140 to connect the tube 130 and the heat radiation fin 140. The junction increasing portion 230 can be formed. Here, the heating unit 220 may include an electric heater disposed in the expansion tube 210, but is not limited thereto, and the heating unit 220 may include various types of known heaters. At this time, the junction enhancement portion 230 formed by melting the clad layer may be referred to as a second junction enhancement portion. Accordingly, the junction increasing portion 145 of the heat dissipation fin 140 disposed in the heat exchanger according to the embodiment may be referred to as a first junction increasing portion.

또한, 도 13에 도시된 바와 같이, 실시예에 따른 열교환기의 튜브(130)와 방열 핀(140)을 이용한 확관 작업시에도, 실시예에 따른 열교환기는 방열 핀(140)의 접합 증대부(145)와 함께 상기 클래드 층을 녹아 형성되는 접합 증대부(230)를 통해 튜브(130)와 방열 핀(140)의 결합력 및 열교환 효율을 더욱 증대시킬 수 있다.In addition, as shown in FIG. 13, even during expansion operation using the tube 130 and the heat dissipation fin 140 of the heat exchanger according to the embodiment, the heat exchanger according to the embodiment increases the junction of the heat dissipation fin 140 (145) ), the bonding strength of the tube 130 and the heat dissipation fin 140 and the heat exchange efficiency can be further increased through the junction increase unit 230 formed by melting the clad layer.
