Description

엔드플레이트에 튜브지지부가 형성된 핀-튜브형 열교환기{PIN-TUBE TYPE HEAT EXCHANGER HAVING END PLATE EQUIPPED WITH TUBE SUPPORTING PART}Fin-tube type heat exchanger with tube support on the end plate {PIN-TUBE TYPE HEAT EXCHANGER HAVING END PLATE EQUIPPED WITH TUBE SUPPORTING PART}

본 발명은 엔드플레이트에 튜브지지부가 형성된 핀-튜브형 열교환기에 관한 것으로, 보다 상세하게는 엔드플레이트에 튜브를 삽입한 후 용접 시 용접 불량이 발생하는 것을 방지하기 위하여 엔드플레이트에 튜브의 끝단을 지지할 수 있는 구조를 적용한 핀-튜브형 열교환기에 관한 것이다.The present invention relates to a fin-tube type heat exchanger in which a tube support is formed on an end plate, and more particularly, to support the end of the tube on the end plate in order to prevent welding defects from occurring after the tube is inserted into the end plate. The fin-tube type heat exchanger to which the structure can be applied.

일반적으로 난방장치는 연료의 연소에 의한 배기가스와 난방수와의 열교환이 이루어지는 열교환기를 구비함으로써 가열된 난방수를 이용하여 난방을 수행하거나 온수를 공급하게 된다. In general, the heating device is provided with a heat exchanger that performs heat exchange between the exhaust gas and the heating water by combustion of the fuel to perform heating using the heated heating water or supply hot water.

도 1은 종래의 열교환기를 보여주는 단면개략도이다. 열교환기는, 내부에 난방수가 흐르는 다수의 튜브(10)와, 상기 튜브(10)의 외주면에 일정 간격으로 용접 결합되는 다수의 핀(20)과, 상기 튜브(10)의 양 끝단이 삽입 지지되도록 양측에 설치되는 엔드플레이트(30) 및, 인접하는 2개의 튜브(10) 끝단을 연결시키는 다수의 U자형튜브(40)로 구성된다. 1 is a schematic cross-sectional view showing a conventional heat exchanger. The heat exchanger includes a plurality of tubes 10 through which heating water flows, a plurality of fins 20 welded to the outer circumferential surface of the tube 10 at regular intervals, and both ends of the tube 10 are inserted and supported. End plate 30 is installed on both sides, and consists of a plurality of U-shaped tube 40 connecting the ends of two adjacent tubes (10).

이러한 열교환기는 U자형튜브(40)를 가공하기 위한 가공비가 많이 들고, U자형튜브(40)를 벤딩(Bending)하기 위한 최소한의 반경이 필요하므로 열교환기를 소형화시키기에 한계가 있다.Such a heat exchanger has a high processing cost for processing the U-shaped tube 40, and requires a minimum radius to bend the U-shaped tube 40, thereby limiting the miniaturization of the heat exchanger.

도 2는 종래의 다른 열교환기를 보여주는 단면개략도, 도 3은 도 2의 버링부를 보여주는 확대도이다. Figure 2 is a schematic cross-sectional view showing another conventional heat exchanger, Figure 3 is an enlarged view showing a burring portion of FIG.

도 2에 도시된 열교환기는 도 1의 열교환기를 개선한 것으로, U자형튜브 대신에 내부에 형성된 유로 공간이 튜브(10)와 연결된 유로캡(41,42)을 사용한 것이다. 엔드플레이트(31)의 튜브가 삽입되는 부분에는 버링부(31a)가 형성되어 있다. The heat exchanger illustrated in FIG. 2 is an improvement of the heat exchanger of FIG. 1, and uses flow path caps 41 and 42 connected to the tube 10 by a flow path space formed therein instead of the U-shaped tube. The burring part 31a is formed in the part into which the tube of the end plate 31 is inserted.

열교환기의 제조 과정을 살펴보면, 핀(10)과 튜브(20)가 결합된 상태에서 엔드플레이트(31)를 튜브(20)의 양단에 결합시킨다. 그 후 도 3에서와 같이 용재도포부(A지점)에 용재를 도포한 후 브레이징 용접을 한다. 이 경우 엔드플레이트(31)와 튜브(20) 사이의 브레이징 용접 불량이 발생하는 문제점이 있다.Looking at the manufacturing process of the heat exchanger, the end plate 31 is coupled to both ends of the tube 20 in a state in which the fin 10 and the tube 20 are coupled. After that, as shown in Figure 3 to apply the material to the material coating (point A) and then brazing welding. In this case, there is a problem in that a brazing welding defect occurs between the end plate 31 and the tube 20.

도 4는 종래의 다른 열교환기를 보여주는 단면개략도, 도 5는 유로캡을 보여주는 개략도, 도 6은 튜브와 엔드플레이트의 접합부를 보여주는 확대도이다. Figure 4 is a schematic cross-sectional view showing another conventional heat exchanger, Figure 5 is a schematic view showing a flow path cap, Figure 6 is an enlarged view showing a junction of the tube and the end plate.

도 4에 도시된 열교환기는 튜브(10) 사이의 간격을 좁혀 열교환기를 소형화시킨 것이다. 이 경우 튜브(10) 사이의 간격이 좁기 때문에 엔드플레이트(32)에 버링부를 형성하기 어렵다. The heat exchanger shown in FIG. 4 is a miniaturized heat exchanger by narrowing the gap between the tubes 10. In this case, since the gap between the tubes 10 is narrow, it is difficult to form a burring portion in the end plate 32.

또한 도 5에 도시된 바와 같이 유로캡(43)에 평탄부(43a)를 형성하기 어렵기 때문에 유로캡(43)과 엔드플레이트(32) 사이의 브레이징이 어려워진다. In addition, as shown in FIG. 5, since it is difficult to form the flat portion 43a in the flow path cap 43, the brazing between the flow path cap 43 and the end plate 32 becomes difficult.

따라서 도 6에 도시된 바와 같이 엔드플레이트(32)에 버링부를 형성시키지 않음으로써 유로캡(43)의 평탄부를 어느 정도 확보할 수가 있다. 그러나 엔드플레이트(32)에 버링부가 형성되어 있지 않아 튜브(10)와 엔드플레이트(32) 사이의 브레이징 용접 불량이 발생하는 문제점이 있다.Therefore, as shown in FIG. 6, the flat portion of the flow path cap 43 can be secured to some extent by not forming a burring portion in the end plate 32. However, since the burring portion is not formed in the end plate 32, there is a problem in that a brazing welding defect occurs between the tube 10 and the end plate 32.

본 발명은 상술한 문제점을 해결하기 위해 안출된 것으로, 튜브와 엔드플레이트 사이의 용접불량을 방지할 수 있는 핀-튜브형 열교환기를 제공하고자 함에 그 목적이 있다.The present invention has been made to solve the above problems, and an object thereof is to provide a fin-tube type heat exchanger that can prevent a welding defect between the tube and the end plate.

상기 목적을 달성하기 위한 본 발명은, 내부에 난방수가 흐르는 다수의 튜브와, 상기 튜브의 외주면에 일정 간격으로 용접 결합되는 다수의 핀과, 상기 튜브의 양 끝단이 삽입 지지되도록 양측에 설치되는 엔드플레이트 및, 상기 엔드플레이트의 외측에 결합되고 내부에 형성된 유로 공간이 상기 튜브와 연결되는 유로캡으로 구성된 핀-튜브형 열교환기에 있어서, 상기 엔드플레이트에는, 상기 튜브와 접합되는 부분에 버링부가 형성되고, 상기 버링부의 끝단에서 연장되어 상기 튜브의 끝단을 지지하기 위한 튜브지지부가 형성된 것을 특징으로 한다.The present invention for achieving the above object, a plurality of tubes flowing heating water therein, a plurality of pins are welded to the outer peripheral surface of the tube at regular intervals, and the end is installed on both sides so that both ends of the tube is inserted and supported In the fin-tube type heat exchanger consisting of a plate and a flow path cap coupled to the outside of the end plate and formed in the flow path, the burring portion is formed at a portion of the end plate joined to the tube. It extends from the end of the burring portion is characterized in that the tube support for supporting the end of the tube is formed.

이 경우 상기 버링부는 상기 튜브 내부를 흐르는 유체의 방향과 평행하고, 상기 튜브지지부는 상기 튜브 내부를 흐르는 유체의 방향과 직각인 것으로 구성될 수 있다.In this case, the burring portion may be parallel to the direction of the fluid flowing in the tube, the tube support portion may be configured to be perpendicular to the direction of the fluid flowing in the tube.

상기 튜브지지부의 끝단은 상기 튜브의 내주면과 일치하는 것으로 구성될 수 있다.The end of the tube support may be configured to coincide with the inner circumferential surface of the tube.

본 발명에 의하면, 열교환기를 소형화하면서도 튜브와 엔드플레이트 사이에 발생하는 용접불량을 방지할 수 있어 열교환기의 품질을 향상시킬 수 있다.According to the present invention, it is possible to prevent welding defects occurring between the tube and the end plate while miniaturizing the heat exchanger, thereby improving the quality of the heat exchanger.

이하 첨부한 도면을 참조하여 본 발명의 바람직한 실시예에 대한 구성 및 작용을 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation of the preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 7은 본 발명의 일실시예에 의한 열교환기 전체 구조를 보여주는 단면개략도이다.7 is a schematic cross-sectional view showing the entire structure of a heat exchanger according to an embodiment of the present invention.

본 발명은, 내부에 난방수가 흐르는 다수의 튜브(110)와, 상기 튜브(110)의 외주면에 일정 간격으로 용접 결합되는 다수의 핀(120)과, 상기 튜브(110)의 양 끝단이 삽입 지지되도록 양측에 설치되는 엔드플레이트(131,132) 및, 상기 엔드플레이트(131,132)의 외측에 결합되고 내부에 형성된 유로 공간이 상기 튜브와 연결되는 유로캡(141,142)으로 이루어진다.According to the present invention, a plurality of tubes 110 through which heating water flows, a plurality of fins 120 welded to the outer circumferential surface of the tube 110 at regular intervals, and both ends of the tube 110 are inserted and supported. End plates 131 and 132 installed on both sides thereof, and flow path caps 141 and 142 coupled to the outside of the end plates 131 and 132 and formed therein, are connected to the tube.

상기 엔드플레이트(131,132)는 좌우측에 2개가 배치되어 튜브(110)를 지지하도록 되어 있다. 엔드플레이트(131,132)는 평판 형상에 튜브(110)의 끝단이 삽입될 수 있도록 구멍이 천공되어 있다. 튜브(110)와의 용접을 위해 천공된 구멍 가장자리를 버링(burring) 공정에 의해 튜브(110) 내부를 흐르는 유체의 방향과 평행하도록 90도 절곡된 형상으로 하여 절곡부를 형성하는 한편, 상기 튜브(110)의 끝단을 지지하기 위해 버링부의 끝단에서 90도 방향으로 절곡되어 튜브(110) 내부를 흐르는 유체의 방향과 수직하도록 튜브지지부가 형성되어 있다.Two end plates 131 and 132 are disposed at left and right sides to support the tube 110. The end plates 131 and 132 are perforated to allow the end of the tube 110 to be inserted into a flat plate shape. The bent portion is formed to be bent 90 degrees parallel to the direction of the fluid flowing through the inside of the tube 110 by a burring process to form a bent portion, while the tube 110 is welded with the tube 110. The tube support is bent to be perpendicular to the direction of the fluid flowing in the tube 110 to be bent in the 90-degree direction from the end of the burring portion to support the end of the).

상기 유로캡(141,142)은 엔드플레이트(131,132) 및 튜브(110) 양 끝단을 덮 는 형상으로서 내부에 빈 공간이 형성되어 튜브(110)를 통해 유입된 난방수가 흐르는 난방유로를 제공하게 된다.The flow path caps 141 and 142 cover both ends of the end plates 131 and 132 and the tube 110, and an empty space is formed therein to provide a heating flow path through which the heating water flowing through the tube 110 flows.

일측에 설치된 유로캡(141)은 평탄부(141a)가 오목하게 형성되어 엔드플레이트(131)와 용접 결합된다. 이로 인해 유로캡(141) 내부는 2개의 공간으로 분리되어 서로 독립된 난방수 유로를 형성하게 된다. 또한 타측에 다른 유로캡(142)이 결합됨으로써 난방수가 2개의 유로캡(141,142)을 경유하면서 지그재그 방향으로 흐르도록 되어 있다.The flow path cap 141 installed on one side of the flow path cap 141 is concave and welded to the end plate 131. As a result, the interior of the flow path cap 141 is divided into two spaces to form independent heating water flow paths. In addition, the other channel cap 142 is coupled to the other side so that the heating water flows in the zigzag direction while passing through the two channel caps 141 and 142.

도 8은 엔드플레이트에 형성된 튜브지지부를 보여주는 상세도이다.8 is a detailed view showing the tube support formed in the end plate.

도 8에서는 일측의 엔드플레이트(131)에 대해서만 도시되어 있으나, 타측의 엔드플레이트(132)도 동일한 형상으로 되어 있다. In FIG. 8, only one end plate 131 is illustrated, but the other end plate 132 has the same shape.

엔드플레이트(131)의 몸체는 튜브(110)가 삽입되도록 구멍(131d)이 천공되어 있고, 상기 구멍(131d)의 가장자리부에는 버링(burring) 공정에 의해 90도 절곡된 버링부(131a)가 형성되어 있다. 상기 버링부(131a)의 끝단에는 구멍(131d)의 내측 방향으로 90도 절곡된 튜브지지부(131b)가 형성되어 있다.The body of the end plate 131 is perforated with a hole 131d so that the tube 110 is inserted, and the burring portion 131a bent at 90 degrees by a burring process is formed at the edge of the hole 131d. Formed. The end of the burring portion 131a is formed with a tube support portion 131b bent 90 degrees in the inner direction of the hole 131d.

상기 버링부(131a)와 튜브지지부(131b)가 연결되는 절곡부 내측은 브레이징 용접시 용재가 도포되는 용재도포부(131c)가 된다.The inside of the bent portion where the burring portion 131a and the tube support portion 131b are connected is a material coating portion 131c to which a material is applied during brazing welding.

도 9는 엔드플레이트에 튜브가 결합된 상태를 보여주는 단면도이다.9 is a cross-sectional view showing a state in which the tube is coupled to the end plate.

튜브(110)의 끝단이 버링부(131a) 내측에 삽입되고 튜브(110)의 끝단 면(110a)이 튜브지지부(131b) 내측에 밀착된다. 이 상태에서 브레이징 용접을 하게 된다. 이 경우 튜브(110)의 내주면과 튜브지지부(131b) 끝단은 수평 상태에서 일치하도록 튜브지지부부(131b)의 길이를 설정하는 것이 바람직하다. 튜브지지부(131b)의 길이가 짧은 경우에는 브레이징 용접 품질이 저하될 수 있고, 튜브지지부(131b)의 길이가 긴 경우에는 튜브(110) 내부를 흐르는 난방수의 유로를 가로 막기 때문이다.The end of the tube 110 is inserted into the burring portion 131a and the end surface 110a of the tube 110 is in close contact with the inside of the tube support 131b. In this state, brazing welding is performed. In this case, the inner circumferential surface of the tube 110 and the end of the tube support part 131b may preferably set the length of the tube support part 131b so as to coincide in a horizontal state. If the length of the tube support 131b is short, the brazing welding quality may be degraded. If the length of the tube support 131b is long, it blocks the flow path of the heating water flowing inside the tube 110.

상기와 같은 구성으로 이루어진 열교환기의 제조공정은 다음과 같다.The manufacturing process of the heat exchanger which consists of such a structure is as follows.

엔드플레이트(131)와 유로캡(141) 사이에 용재를 삽입한 후 엔드플레이트(131)와 유로캡(141)을 스폿 용접(spot welding) 등을 이용하여 가접시킨다. 이렇게 함으로써 유로캡(141)의 평탄부(141a)가 좁더라도 유로캡(141)의 평탄부(141a)와 엔드플레이트(131)를 밀착시킬 수 있으므로 종래 브레이징 공정시 엔드플레이트와 유로캡 사이에서 발생하던 브레이징 불량을 방지할 수 있다.After inserting the material between the end plate 131 and the flow path cap 141, the end plate 131 and the flow path cap 141 are welded by spot welding. By doing so, even if the flat portion 141a of the flow path cap 141 is narrow, the flat portion 141a of the flow path cap 141 and the end plate 131 can be brought into close contact with each other. It can prevent the bad brazing.

엔드플레이트(131)와 유로캡(141)이 가접으로 조립된 상태에서, 도 8에 도시된 용재도포부(131c)에 용재를 바르고 튜브(110)를 조립한 후 브레이징을 한다. 이 경우 튜브(110)와 엔드플레이트(131)는 버링부(131a) 뿐만 아니라 튜브지지부(131b)도 브레이징이 되므로 종래 튜브(110)와 엔드플레이트(131) 사이에서 발생하던 브레이징 불량이 방지된다.In the state where the end plate 131 and the flow path cap 141 are assembled by welding, the material is applied to the material coating part 131c shown in FIG. 8 and the brazing is performed after the tube 110 is assembled. In this case, the tube 110 and the end plate 131 are brazing not only the burring portion 131a but also the tube support portion 131b, thereby preventing the brazing defects that occurred between the tube 110 and the end plate 131.

이상에서는 본 발명을 바람직한 실시예에 의거하여 설명하였으나, 본 발명은 상기 실시예에 한정되는 것은 아니며, 본 발명의 기술적 사상의 범위 내에서 이 기술분야에서 통상의 지식을 가진 자에 의하여 여러 가지 변형이 가능하다.In the above described the present invention based on the preferred embodiment, the present invention is not limited to the above embodiment, various modifications by those skilled in the art within the scope of the technical idea of the present invention This is possible.
