Description
본 고안은 가스보일러의 열교환기에 관한 것으로, 더욱 상세하게는 사각 케이싱 외벽에 급수파이프가 나선형으로 배치되어 열교환부로 공급되는 물을 예열함과 동시에 사각 케이싱의 과열을 방지하는 가스보일러의 열교환기에 관한 것이다.The present invention relates to a heat exchanger of a gas boiler, and more particularly, to a heat exchanger of a gas boiler that preheats water supplied to a heat exchanger by spirally arranging a water supply pipe on an outer wall of a rectangular casing and prevents overheating of the rectangular casing. .
일반적으로 가정에서 난방 및 온수공급을 위해 사용하는 보일러는 연료에 따라 기름보일러와 가스보일러로 대별된다. 또한, 가스보일러는 액화석유가스(LPG)를 원료로 사용하는 경우도 있으나, 경유나 등유에 비해 황분을 거의 함유하고 있지 않아 대기오염을 최소화할 수 있는 액화천연가스(LNG)를 대부분 사용하고 있다.In general, boilers used for heating and hot water supply at home are roughly divided into oil boilers and gas boilers depending on the fuel. In addition, gas boilers may use LPG as a raw material, but most of them use LNG, which contains less sulfur than diesel or kerosene to minimize air pollution. .
이러한 가스보일러는 제어방식이나 밀폐상태 또는 난방수를 가열하는 열원에 따라 콘덴싱과, 비콘덴싱 방식으로 구분할 수 있다. 콘덴싱 방식은 버너에 의해 연소된 열을 이용하여 직접적으로 난방수를 가열하는 현열부 열교환기와, 이 현열부 열교환기를 통과한 배기가스의 잠열을 이용하여 난방수를 가열하는 잠열부 열교환기를 구비한다. 그리고 비콘덴싱 방식은 현열부 열교환기만 갖추고 있다.Such gas boilers may be classified into condensing and non-condensing according to a control method, a sealed state, or a heat source for heating heating water. The condensing method includes a sensible heat exchanger for directly heating heating water using heat burned by a burner, and a latent heat exchanger for heating heating water using latent heat of exhaust gas passing through the sensible heat exchanger. And the non-condensing method is equipped only with sensible heat exchanger.
비콘덴싱 방식의 가스보일러에 사용되는 종래 열교환기는 도 1에 도시한 바와 같이, 상하부가 개방되며 내부에는 버너(미도시)를 설치할 수 있도록 연소실(미도시)이 형성된 사각케이싱(1)과, 이 사각케이싱(1)의 내부 상측에 수용 배치되며 다수의 현열핀(2a) 및 난방수 유동관(2b)으로 이루어진 열교환부(2)와, 사각케이싱(1)의 외부 하측에 나선형으로 권선되며 열교환부(2)의 난방수 유동관(2b)과 연결된 급수파이프(3)를 갖추고 있다.As shown in FIG. 1, a conventional heat exchanger used in a non-condensing gas boiler has a rectangular casing 1 having a combustion chamber (not shown) so that upper and lower portions are opened and a burner (not shown) is installed therein, and The heat exchanger 2 accommodated above the inside of the rectangular casing 1 and composed of a plurality of sensible heat fins 2a and a heating water flow pipe 2b, and spirally wound around the outer lower side of the rectangular casing 1 to form a heat exchanger. The feedwater pipe 3 connected with the heating water flow pipe 2b of (2) is provided.
따라서 버너로 가열되는 열교환부(2)의 난방수 유동관(2b)에는 급수파이프(3)를 통해 물이 공급되는데, 물탱크(미도시)로부터 공급되는 물은 급수파이프(3)를 지나면서 사각케이싱(1)의 외벽과 열교환되어 일차로 가열된 상태이기 때문에 열교환부(2)에서는 물이 보다 빨리 히팅된다. 또한, 버너에 의해 사각케이싱(3) 역시 가열되는데, 사각케이싱(1)의 외벽은 물탱크로부터 차가운 물이 유입되는 급수파이프(3)가 감싸고 있기 때문에 이의 과열이 방지된다.Therefore, water is supplied to the heating water flow pipe 2b of the heat exchanger 2 heated by the burner through the water supply pipe 3, and the water supplied from the water tank (not shown) passes through the water supply pipe 3 and is square. Since the heat exchanged with the outer wall of the casing 1 and the primary heating state, the water is heated faster in the heat exchange unit 2. In addition, the square casing 3 is also heated by the burner, and the outer wall of the square casing 1 is surrounded by a feed pipe 3 through which cold water flows from the water tank, thereby preventing overheating thereof.
그러나 이러한 종래 가스보일러의 열교환기 구조에서는 급수파이프(3)가 사각케이싱(1)의 외벽과 선접촉으로 접합되기 때문에, 열교환 효율을 높이거나 사각케이싱(1)의 과열을 방지하는데 그 한계가 있다.However, in the heat exchanger structure of the conventional gas boiler, since the water supply pipe 3 is joined in line contact with the outer wall of the rectangular casing 1, there is a limit in improving heat exchange efficiency or preventing overheating of the rectangular casing 1. .
즉, 원형단면을 갖는 급수파이프(3)가 사각케이싱(1)의 외벽을 나선형으로 감싸면서 선접촉되며, 이 접촉상태를 유지시키기 위해 스폿용접 또는 브레이징 용접을 실시한다. 이에 따라 사각케이싱(1)와 급수파이프(3)와의 선접촉으로 인해 열전달 효율이 그다지 높지 않으며 용접 작업성 역시 난해한 단점이 있다.That is, the water supply pipe 3 having a circular cross section is in line contact while spirally wrapping the outer wall of the rectangular casing 1, and spot welding or brazing welding is performed to maintain this contact state. Accordingly, the heat transfer efficiency is not very high due to the line contact between the rectangular casing 1 and the water supply pipe 3, and the welding workability is also difficult.
본 고안은 이러한 문제점을 해결하기 위한 것으로; 본 고안의 목적은 급수파이프가 나선형으로 권선 배치되어 접합되는 사각케이싱의 외벽 구조를 개선하여 급수파이프와의 열교환 효율을 높이며 용접 작업성을 향상시킬 수 있는 가스보일러의 열교환기를 제공하는 것이다.The present invention is to solve this problem; An object of the present invention is to provide a heat exchanger of a gas boiler that can improve the heat exchange efficiency with the feed pipe and improve the welding workability by improving the outer wall structure of the rectangular casing in which the feed pipe is spirally wound.

사각 케이싱의 하부 외벽에는 급수파이프의 외주 일부가 수용되어 면접촉하도록 안착 그루브가 오목하게 마련된 것을 특징으로 한다.The lower outer wall of the rectangular casing is characterized in that the mounting groove is concave provided so that the outer peripheral portion of the water supply pipe is in contact with the surface.
또한, 안착 그루브는 사각 케이싱 외벽의 직선구간을 따라 일정한 간격으로 성형된 것을 특징으로 한다.In addition, the seating groove is formed at regular intervals along a straight section of the outer wall of the rectangular casing.
이러한 구성에 의하면, 사각 케이싱과 급수파이프의 접촉면적이 증대됨으로써, 열교환 효율이 보다 높아지는 것은 물론이며 접합 작업성 역시 향상시킬 수 있게 된다.According to this structure, by increasing the contact area between the rectangular casing and the feed water pipe, not only can the heat exchange efficiency be higher, but also the joining workability can be improved.
이하, 본 고안에 따른 하나의 바람직한 실시 예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings.
첨부도면을 간략히 설명하면, 도 2는 본 고안이 적용되는 비콘덴싱 가스보일러의 전체적인 구조를 개략적으로 도시한 것이고, 도 3과 도 4는 본 고안에 따른 가스보일러의 열교환기 구조를 발췌하여 보인 것이다.Briefly, the accompanying drawings, Figure 2 schematically shows the overall structure of the non-condensing gas boiler to which the present invention is applied, Figures 3 and 4 is an extract showing the heat exchanger structure of the gas boiler according to the present invention. .
본 고안이 적용되는 비콘덴싱 방식 가스보일러는 도 2에 도시한 바와 같이, 물탱크(10)의 물을 펌프(20)를 통해 물공급관(30)으로 순환시켜 주열교환기(40)에서 버너(50)를 통해 가열하고, 이 가열된 물을 삼방향밸브(60)의 제어 작동으로 온수열교환기(70) 또는 온수공급관(80)으로 선택 공급하여 온수공급 및 난방을 수행하게 된다. 그리고 온수열교환기(70)와 온수공급관(80)으로 공급되어 가열된 물은 온수 공급 및 난방을 위한 열교환을 행한 후 다시 순환되어 펌프(20)에 의해 주열교환기(40)로 제공되는 순환작동을 하게 된다.As the non-condensing gas boiler to which the present invention is applied, as shown in FIG. 2, the water in the water tank 10 is circulated to the water supply pipe 30 through the pump 20 to burner 50 in the main heat exchanger 40. Heated through), and the heated water is selectively supplied to the hot water heat exchanger 70 or the hot water supply pipe 80 by the control operation of the three-way valve 60 to perform hot water supply and heating. The heated water supplied to the hot water heat exchanger 70 and the hot water supply pipe 80 is circulated again after performing heat exchange for hot water supply and heating, and is circulated again to provide the main heat exchanger 40 by the pump 20. Done.
이러한 기능을 하는 주열교환기(40)는 도 2와 도 3에 도시한 바와 같이, 외형 몸체를 이루며 상하부가 개방되게 형성된 사각 케이싱(41)과, 이 사각 케이싱(41)의 상부측에 수용 설치되는 열교환부(43)와, 사각 케이싱(41)의 하부측 외벽(41a)에 권선되어 열교환부(43)측으로 공급되는 물을 예열하기 위한 급수파이프(44)를 갖추고 있는데, 각 구성요소들의 상세한 구조는 다음과 같다.As shown in Figs. 2 and 3, the main heat exchanger 40 having such a function is provided with a rectangular casing 41 which forms an outer body and is open at the top and bottom thereof, and is accommodated and installed at an upper side of the rectangular casing 41. The heat exchanger 43 and the water supply pipe 44 for preheating the water supplied to the heat exchanger 43 by winding on the lower outer wall 41a of the rectangular casing 41, the detailed structure of each component Is as follows.
먼저, 사각 케이싱(41)은 금속(동) 플레이트를 밴딩하여 상하부가 개방된 사각 통형상으로 제작되며, 내부에는 버너(50)가 수용되어 가스 연료가 연소되는 연소실(42)이 형성된다.First, the rectangular casing 41 is manufactured in a rectangular cylindrical shape in which upper and lower portions are opened by bending a metal (copper) plate, and a burner 50 is accommodated therein to form a combustion chamber 42 in which gas fuel is combusted.
그리고 열교환부(43)는 사각 케이싱(41)의 연소실(42) 상부공간에 수용 설치되는 것으로, 병렬로 배치되는 다수의 현열핀(43a)과 이 현열핀(43a)들을 수회 관통하면서 리턴밴드를 통해 연계된 난방수 유동관(43b)으로 이루어져 있다. 이에 따라 연소실(42)의 연소열에 의해 난방수 유동관(43b)을 지나는 물이 히팅되게 된다. 이 때, 난방수 유동관(43b)을 지나는 물은 다수의 현열핀(43a)들에 의해 열교환 작용이 보다 원활하게 이루어진다.The heat exchange part 43 is installed in the upper space of the combustion chamber 42 of the rectangular casing 41, and passes through the plurality of sensible heat fins 43a and the sensible heat fins 43a in parallel and returns the return band. Consists of a heating water flow pipe (43b) linked through. Accordingly, the water passing through the heating water flow pipe 43b is heated by the combustion heat of the combustion chamber 42. At this time, the water passing through the heating water flow pipe 43b is more smoothly heat exchanged by a plurality of sensible heat fins 43a.
또한, 급수파이프(44)는 사각 케이싱(41)의 하부 외벽(41a)에 일정한 간격을 유지하면서 3회 정도 나선형으로 권선 배치된 후 접합되는 것으로, 이의 일단은 펌프(20) 출구측인 물공급관(30)과 연결되며, 이의 타단은 열교환부(3)의 난방수 유동관(43b) 입구측과 연결된다.In addition, the water supply pipe 44 is spirally wound about three times while maintaining a constant distance to the lower outer wall (41a) of the rectangular casing 41 and is joined, one end thereof is a water supply pipe that is the outlet side of the pump 20 It is connected to 30, the other end thereof is connected to the inlet side of the heating water flow pipe 43b of the heat exchange unit (3).
이에 따라 펌프(20)측에서 토출되는 물은 나선형으로 권선된 급수파이프(44)를 지난 후 열교환부(43)의 난방수 유동관(43b)으로 공급되게 된다.Accordingly, the water discharged from the pump 20 side is supplied to the heating water flow pipe 43b of the heat exchanger 43 after passing the spirally wound feed pipe 44.
도 3과 도 4를 참조하면, 이러한 급수파이프(44)의 접합 작업성 및 열교환효율을 높이기 위해, 사각 케이싱(41)의 하부 외벽(41a)에는 안착 그루브(41b;groove)가 오목하게 마련되어 있다.3 and 4, in order to improve the joining workability and heat exchange efficiency of the water supply pipe 44, mounting grooves 41b (grooves) are recessed in the lower outer wall 41a of the rectangular casing 41. .
즉, 안착 그루브(41b)는 사각 케이싱(41)의 외벽(41a)에 일정한 간격으로 성형되어 있어서, 나선형으로 밴딩된 급수파이프(44)의 외주 일부가 안착 수용되어 면접촉하게 된다. 본 고안의 실시 예에서는 사각 케이싱(41)의 외벽(41a) 하부에 급수파이프(44)를 나선형으로 밴딩하여 배치한 후 별도의 지그장치를 통해 사각 케이싱(41)의 외벽(41a) 직선구간을 따라 안착 그루브(41b)를 성형하였다.That is, the seating groove 41b is formed at regular intervals on the outer wall 41a of the rectangular casing 41, so that a part of the outer circumference of the spirally bent water supply pipe 44 is seated and received in surface contact. In the embodiment of the present invention, the water supply pipe 44 is spirally arranged below the outer wall 41a of the rectangular casing 41, and then the straight section of the outer wall 41a of the rectangular casing 41 is separated through a separate jig device. The mounting groove 41b was thus formed.
다음에는 이와 같이 구성된 주열교환기(40)의 사각 케이싱(41)과 급수파이프(44)의 접합 작업 및 이에 따른 작용효과를 설명한다.Next, the operation of joining the rectangular casing 41 and the feed pipe 44 of the main heat exchanger 40 configured as described above and the effects thereof will be described.
먼저, 나선형으로 밴딩된 급수파이프(44)는 사각 케이싱(41) 외벽(41a)의 안착 그루브(41b)를 따라 안착 수용됨으로써, 급수파이프(44)의 외주 일부가 사각 케이싱(41)과 면접촉된 상태로 유지된다.First, the spirally bent water supply pipe 44 is seated and accommodated along the seating groove 41b of the outer wall 41a of the rectangular casing 41 so that a part of the outer circumference of the water supply pipe 44 is in surface contact with the rectangular casing 41. Will remain intact.
이러한 상태에서 별도의 지그장치를 통해 사각 케이싱(41)과 급수파이프(44)를 고정시킨 후 스폿용접 또는 브레이징 용접을 실시하면, 나선형 급수파이프(44)는 사각 케이싱(41)의 외벽(41a)에 견실하게 고정된다.In this state, if the square casing 41 and the water supply pipe 44 are fixed through a separate jig device and then spot welding or brazing welding is performed, the spiral water supply pipe 44 is the outer wall 41a of the square casing 41. It is firmly fixed to.
이 때, 나선형 급수파이프(44)는 안착 그루브(41b)를 따라 면접촉 상태로 유지됨으로써, 이의 접합 작업이 용이하게 이루어짐은 물론이며, 사각 케이싱(41) 외벽(41a)과 보다 넓은 면적으로 접합된다.At this time, the spiral water supply pipe 44 is maintained in the surface contact state along the seating groove 41b, so that the joining operation is easily performed, and the outer casing 41 is joined to the outer wall 41a in a wider area. do.
또한, 가스보일러의 작동 시 나선형 급수파이프(44)를 지나는 물은 사각 케이싱(41)과의 열교환이 보다 원활하게 이루어지며 이로 인해 높은 온도로 예열된물이 열교환부(43)의 난방수 유동관(43b)으로 공급된다. 또한, 버너(50) 열에 의해 사각 케이싱(41) 역시 직접 가열되는데, 이의 외벽(41a)이 나선형 급수파이프(44)와 보다 용이하게 열교환 됨으로써 이의 과열이 방지된다.In addition, during operation of the gas boiler, the water passing through the spiral feed pipe 44 is more smoothly exchanged with the square casing 41, and thus, the water preheated to a high temperature is heated by the heating water flow pipe of the heat exchanger 43. 43b). In addition, the square casing 41 is also directly heated by the burner 50 heat, and its outer wall 41a is more easily heat exchanged with the spiral feed pipe 44 to prevent its overheating.
이상에서 상세히 설명한 바와 같이, 본 고안에 따른 가스보일러의 열교환기에 의하면, 사각 케이싱의 하부 외벽에는 나선형으로 밴딩된 급수파이프의 외주 일부가 안착 수용되어 면접촉하도록 안착 그루브가 직선구간을 따라 오목하게 마련되어 있다. 이에 따라 급수파이프가 사각 케이싱 외벽에 면접촉 상태를 유지하고 있기 때문에, 이의 용접 작업을 보다 용이하게 할 수 있는 작용효과가 있다.As described in detail above, according to the heat exchanger of the gas boiler according to the present invention, a mounting groove is recessed along a straight section so that a portion of the outer circumference of the spirally bent water supply pipe is seated and accommodated on the lower outer wall of the rectangular casing. have. As a result, since the water supply pipe maintains a surface contact with the rectangular casing outer wall, there is an effect of making the welding work easier.
또한, 나선형의 급수파이프가 면접촉됨으로써, 사각 케이싱 외벽과의 열교환이 보다 용이하게 이루어짐은 물론이며 급수파이프를 통해 물을 공급받는 열교환부 역시 열교환 효율이 향상되는 장점이 있다.In addition, as the spiral water supply pipe is in surface contact, heat exchange with the outer wall of the rectangular casing is more easily performed, and the heat exchanger receiving water through the water supply pipe also has an advantage of improving heat exchange efficiency.
또한, 버너 열에 의해 직접 가열되는 사각 케이싱의 과열이 효과적으로 방지되는 장점이 있다.In addition, there is an advantage that the overheating of the rectangular casing directly heated by the burner heat is effectively prevented.
