열교환기 및 이를 구성하는 열교환배관{Heat exchanger and heat exchanging pipe composing thereof}Heat exchanger and heat exchanging pipe composing

본 발명은 보일러에 사용되는 열교환기 및 이를 구성하는 열교환배관에 관한 것으로서, 더욱 상세하게는 난방수유입구와 난방수유출구 사이의 유로를 형성하고 내부로는 난방수가 통과하면서 연소가스와의 접촉으로 열교환이 이루어지는 열교환배관의 제작을 용이하게 하고, 상기 열교환배관의 양측 끝단이 삽입되어 결합되는 엔드플레이트와 정확하게 상호 결합이 이루어지는 열교환기 및 이를 구성하는 열교환배관에 관한 것이다.The present invention relates to a heat exchanger used in a boiler and a heat exchange pipe constituting the same, and more particularly, to form a flow path between a heating water inlet and a heating water outlet, and to exchange heat with contact with combustion gas while the heating water passes therein. The present invention relates to a heat exchanger for facilitating the production of the heat exchange pipes formed thereon, and the heat exchanger constituting the heat exchanger that is precisely mutually coupled to an end plate to which both ends of the heat exchange pipe are inserted and coupled.

일반적으로 연소실 내에서 열교환배관 내부를 따라 흐르는 난방수를 버너를 이용하여 가열할 수 있는 구성을 가진 연소기기에는 크게 보일러와 온수기 등을 들 수 있다. In general, a combustion apparatus having a configuration capable of heating the heating water flowing along the inside of a heat exchange pipe in a combustion chamber by using a burner includes a boiler and a water heater.

즉, 일반 가정이나 공공건물 등에 사용되는 보일러는 난방용이나 온수용으로 이용되고, 온수기는 냉수를 단시간 내에 소정의 온도로 가열하여 사용자가 편리하게 온수를 사용할 수 있도록 하는 것이다.That is, a boiler used in a general home or a public building is used for heating or hot water, and a water heater heats cold water to a predetermined temperature within a short time so that a user can conveniently use hot water.

이러한 보일러나 온수기와 같은 연소기기는 대부분 기름 혹은 가스를 연료로 사용하여 버너를 통해 연소시킨 다음, 이 연소과정에서 발생하는 연소열을 이용하여 물을 가열하고, 이 가열된 물(온수)을 사용자의 필요에 따라 제공할 수 있는 시스템을 가지고 있다.Most combustors such as boilers and water heaters use oil or gas as fuel to combust through a burner, and then heat water using combustion heat generated during the combustion process, and the heated water (hot water) I have a system that can provide it as needed.

상기와 같은 연소기기에는 버너로부터 발생한 연소열을 흡수하기 위하여 열교환기가 구비되어 있다.The combustion apparatus as described above is provided with a heat exchanger to absorb the combustion heat generated from the burner.

도 1은 종래 U-튜브를 이용한 열교환기의 구조를 보여주는 정면개략도이고, 도 2는 종래 캡(Cap)을 이용한 열교환기의 구조를 보여주는 정면개략도이다.Figure 1 is a front schematic view showing the structure of a heat exchanger using a conventional U-tube, Figure 2 is a front schematic view showing the structure of a heat exchanger using a conventional cap (Cap).

열교환기(1,2)는 난방수가 유입되는 난방수유입구(10)와, 상기 난방수유입구(10)로부터 유입된 난방수가 내부를 통과하며 표면에서 연소가스와 접촉되어 열전달이 이루어지는 복수의 열교환배관(21,22,23)으로 이루어진 열교환부(20)와, 상기 열교환배관(21,22,23)을 통과하면서 가열된 난방수가 유출되는 난방수유출구(30)로 이루어진다.The heat exchangers 1 and 2 have a heating water inlet 10 through which heating water flows in, and a plurality of heat exchange pipes through which heat is introduced from the heating water inlet 10 and in contact with the combustion gas on the surface thereof for heat transfer. It consists of a heat exchange unit 20 made of (21, 22, 23), and a heating water outlet 30 through which the heated heating water flows out while passing through the heat exchange pipes (21, 22, 23).

상기 열교환배관(21,22,23)의 양측 끝단은 엔드플레이트(11,31)에 관통 형성된 배관삽입구멍에 삽입되어 용접결합되고, 상기 엔드플레이트(11,31)의 외측으로는 도 1에 도시된 U-튜브(12,14) 또는 도 2에 도시된 캡(32,34)을 통하여 열교환배관(21,22,23) 내부를 흐르는 난방수의 유로가 연결된다.Both ends of the heat exchange pipes (21, 22, 23) are inserted into the pipe insertion hole formed through the end plates (11, 31) and welded, and the outside of the end plates (11, 31) shown in Figure 1 Through the U-tubes 12 and 14 or the caps 32 and 34 shown in FIG. 2, a flow path of heating water flowing inside the heat exchange pipes 21, 22 and 23 is connected.

도 2에 도시된 바와 같이, 캡(32,34)의 내측면과 엔드플레이트(11,31)의 외측면과의 사이에는 실링(35)을 구비하여 난방수가 유로 이외의 영역으로 새어나가지 못하도록 기밀을 유지하게 된다.As shown in FIG. 2, a seal 35 is provided between the inner surfaces of the caps 32 and 34 and the outer surfaces of the end plates 11 and 31 to prevent the heating water from leaking to areas other than the flow path. Will be maintained.

상기 열교환배관(21,22,23) 사이는 소정의 간격으로 이격되어 있어 그 사이 로 고온의 연소가스가 통과하면서 열전달이 이루어지며, 열전달 효율을 향상시키기 위하여 상기 열교환배관(21,22,23)의 표면에는 전열핀(25)이 다수 형성되어 있다.The heat exchange pipes (21, 22, 23) are spaced at predetermined intervals, so that the heat transfer is carried out while the high-temperature combustion gas passes therebetween, the heat exchange pipes (21, 22, 23) to improve the heat transfer efficiency On the surface of the heat transfer fin 25 is formed a large number.

상기 열교환기(1,2)에 사용되는 열교환배관(21,22,23)은 다양한 재질과 구조로 제작될 수 있다.The heat exchange pipes 21, 22, and 23 used in the heat exchangers 1 and 2 may be manufactured in various materials and structures.

일례로서, 동(brass)을 재료로 하여 제작되는 열교환배관의 경우에는 재료비가 고가(高價)일 뿐만 아니라, 사용중 열교환배관의 표면에 맺히는 응축수로 인해 열교환배관이 부식되는 문제점이 있으므로 콘덴싱 보일러의 잠열교환기에는 사용이 부적합하여 사용환경이 제한되는 문제점이 있다.For example, in the case of a heat exchanger pipe made of copper, the material cost is not only high, and the latent heat of the condensing boiler is corroded by the condensed water that forms on the surface of the heat exchanger pipe during use. There is a problem that the use environment is limited because the exchange is not suitable for use.

한편, 열교환배관을 제작하는 공정은 조관(造管), 열처리, 인발, 절단 등 일련의 공정을 거치게 되는데, 스테인리스(stainless)를 재료로 하여 제작되는 열교환배관의 경우에는 그 재료의 특성상 열교환배관의 형상을 정확하게 제작하기가 어려운 문제점이 있다.On the other hand, the process of manufacturing the heat exchange pipe goes through a series of processes such as pipe, heat treatment, drawing, cutting, etc. In the case of heat exchange pipes made of stainless material, due to the characteristics of the material, There is a problem that it is difficult to manufacture the shape accurately.

만일 열교환배관의 형상이 정확한 치수로 제작되지 않을 경우에는, 열교환배관의 표면에 전열핀을 조립하거나, 열교환배관과 엔드플레이트를 조립하기가 어렵게 되는 문제점이 있다.If the shape of the heat exchange pipe is not manufactured to the correct dimensions, it is difficult to assemble the heat transfer fins on the surface of the heat exchange pipe, or to assemble the heat exchange pipe and the end plate.

또한, 열교환배관과 전열핀, 열교환배관과 엔드플레이트는 전기용접이나 브레이징(brazing)용접으로 결합시키게 되는데, 열교환배관의 치수가 정확하지 않으면 용접이 잘 되지 않는 문제점이 있다.In addition, the heat exchange pipe and the heat transfer fin, the heat exchange pipe and the end plate is coupled by electric welding or brazing (brazing) welding, there is a problem that the welding is not well if the dimensions of the heat exchange pipe is not accurate.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 제작이 용이할 뿐만 아니라 엔드플레이트에 정확한 치수로 용접결합 가능한 열교환배관을 포함하는 열교환기 및 이를 구성하는 열교환배관을 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, and the object of the present invention is to provide a heat exchanger and a heat exchanger pipe constituting the heat exchanger pipe including a heat exchanger pipe weldable to the end plate with the correct dimensions. .

상술한 바와 같은 목적을 구현하기 위한 본 발명의 열교환배관은, 난방수가 내부를 통과하고 연소가스와 접촉되어 열교환이 이루어지며 길이 방향의 양측 끝단이 엔드플레이트에 삽입되어 결합되는 열교환배관에 있어서, 상기 열교환배관은 일정한 폭을 갖는 금속 박판의 폭 방향의 양측 끝단이 외측으로 일정 길이 돌출되어 서로 맞대어져 접하는 플랜지부를 형성하도록 절곡된 것을 특징으로 한다.In the heat exchange pipe of the present invention for realizing the object as described above, in the heat exchange pipe that the heating water passes through the inside and is in contact with the combustion gas, the heat exchange is made and both ends of the longitudinal direction are inserted into the end plate and combined; The heat exchange pipe is characterized in that both ends of the width direction of the metal thin plate having a predetermined width is bent to form a flange portion protruding a predetermined length to the outside to be in contact with each other.
