Description
본 발명은 가스보일러의 전열핀 구조에 관한 것으로서, 보다 상세하게는 열핀으로 전조 가공되는 알루미늄 재질을 이용하여 전열면적을 증가시켜 열교환 효율을 현격하게 높일 수 있을 뿐만 아니라 제품의 원가를 절감시키고 제품을 컴팩트화시킬 수 있도록 한 가스보일러의 전열핀 구조에 관한 것이다.The present invention relates to a heat transfer fin structure of a gas boiler, and more particularly, by using an aluminum material that is rolled into a heat fin, the heat transfer area can be increased to significantly increase the heat exchange efficiency, as well as reduce the cost of the product and improve the product. The heating fin structure of the gas boiler to be compact.
일반 가정이나 공공건물 등에 사용되는 보일러는 난방용이나 온수용으로 이용된다.Boilers used in homes and public buildings are used for heating or hot water.
이러한 보일러는 제공되는 연료의 형태에 따라 기름보일러와 가스보일러로 구분된다.These boilers are divided into oil boilers and gas boilers according to the type of fuel provided.
동일한 용량을 갖는 기름 및 가스보일러를 비교해보면 구입가격에 있어서 기름보일러가 가스보일러에 비해 저렴하나 가스보일러가 기름보일러에 비해 연료 소모량이 적다는 이점이 있다.When comparing oil and gas boilers having the same capacity, oil boilers are cheaper than gas boilers in terms of purchase price, but gas boilers have less fuel consumption than oil boilers.
그러나, 장기적으로 볼 때, 소비자가 부담해야 하는 경비는 기름 및 가스보일러 모두가 거의 동일하다 할 수 있다.However, in the long run, the cost to consumers is almost the same for both oil and gas boilers.
이에, 도시가스가 공급되는 지역이라면 가스보일러를 사용하고 도시가스가 공급되지 않는 기타의 지역에서는 기름보일러를 많이 이용하게 된다.Therefore, gas boilers are used when the city gas is supplied, and oil boilers are frequently used in other areas where the city gas is not supplied.
근자에 들어서는 도시가스가 공급되는 지역의 증가로 인해 점차 가스보일러의 사용이 증가되고 있다.In recent years, the use of gas boilers is gradually increasing due to the increase of the city gas supply area.
종래의 가스보일러는 내부에 연소실이 형성되어 있으며, 연소실의 하부에는 가스버너가 마련되어 있고, 상부에는 열교환기가 마련되어 있다.In the conventional gas boiler, a combustion chamber is formed therein, a gas burner is provided at a lower portion of the combustion chamber, and a heat exchanger is provided at an upper portion thereof.
이에, 가스버너가 작동되면 연소실 내로 유입된 물은 열교환기에 의해 열교환되어 그 온도가 상승된 후, 난방 및 온수배관 등으로 제공된다.Thus, when the gas burner is operated, water introduced into the combustion chamber is heat-exchanged by a heat exchanger, and the temperature thereof is raised, and then provided to the heating and hot water pipes.
그런데, 이러한 종래의 가스보일러에 있어서는, 연소실 내에 마련된 열교환기 자체만으로 열교환이 이루어지고 있는 바, 그 전열면적에 한계가 있다.By the way, in such a conventional gas boiler, since heat exchange is performed only by the heat exchanger itself provided in the combustion chamber, the heat transfer area is limited.
따라서, 전열면적을 증가시키고자 한다면 열교환기 자체를 크게 설계해야 하므로 가스보일러를 컴팩트화 할 수 없다는 결점이 있다.Therefore, if the heat transfer area is to be increased, the heat exchanger itself needs to be largely designed, so the gas boiler cannot be compacted.
또한, 종래의 가스보일러에 채용되는 열교환기는 열핀튜브(High finned tube)를 사용하지 않고 수관부의 파이프에 전열핀을 용접하여 사용하고 있으므로 열전달 성능이 저하될 수밖에 없다.In addition, since the heat exchanger used in the conventional gas boiler is used by welding the heat transfer fin to the pipe of the water pipe part without using a high finned tube, the heat transfer performance is inevitably deteriorated.
만일, 전열면적을 확보하기 위해 전열핀을 더 사용하게 되면, 사용하는 전열핀 만큼의 재료비가 상승하게 되고 제품의 사이즈가 커지며 전열핀의 별도 생산, 용접 공정의 추가 등으로 인한 생산비용이 상승하는 문제점이 있다.If the heat transfer fin is used to secure the heat transfer area, the material cost increases as much as the heat transfer fin used, the size of the product increases, and the production cost increases due to the additional production of the heat transfer fin and the addition of the welding process. There is a problem.
본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 열핀으로 전조 가공되는 알루미늄 재질을 이용하여 전열면적을 증가시켜 열교환 효율을 현격하게 높일 수 있도록 한 가스보일러의 전열핀 구조를 제공하는데 있는 것이다.The present invention has been made to solve the above problems, the object of the present invention is to increase the heat transfer area by using an aluminum material that is rolled into a hot fin heat transfer fin structure of the gas boiler to significantly increase the heat exchange efficiency Is to provide.
또한, 본 발명의 다른 목적은, 제품의 원가를 절감시킬 뿐만 아니라 제품을 컴팩트화시킬 수 있도록 한 가스보일러의 전열핀 구조를 제공하는데 있는 것이다.In addition, another object of the present invention is to provide a heat-transfer fin structure of a gas boiler that can reduce the cost of the product as well as compact the product.

Is achieved.
이하에서는 첨부도면을 참조하여 본 발명에 대해 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 가스보일러의 개략적인 구성도이다.1 is a schematic configuration diagram of a gas boiler according to the present invention.
도면에 도시된 바와 같이, 본 발명에 따른 가스보일러는, 외관을 형성하는 연소실커버(10)와, 연소실커버(10)의 상부에 마련된 배기가스안내판(20)을 갖는다.As shown in the figure, the gas boiler according to the present invention has a combustion chamber cover 10 forming an appearance and an exhaust gas guide plate 20 provided on the combustion chamber cover 10.
상기 연소실커버(10)는 통상적으로 사각박스 형상으로 이루어지나, 설치되는 장소 혹은, 가스보일러의 효율 및 용량, 그리고 디자인에 따라 원통형상이나 기타 다른 형상을 이룰 수도 있고, 연소실커버(10) 내에는 연소실(10a)이 형성되어 있다.The combustion chamber cover 10 is generally formed in a rectangular box shape, but may also have a cylindrical shape or other shape according to the installation location or efficiency and capacity of the gas boiler, and the design thereof. The combustion chamber cover 10 may include a combustion chamber. 10a is formed.
그리고, 상기 연소실커버(10)의 일측에는 도시 않은 난방 및 온수배관으로부터 물이 환수되는 환수관(12)이 마련되어 있으며, 타측에는 후술할 내부열교환관 (28) 및 열교환기(24)에 의해 데워진 온수가 다시 난방 및 온수배관으로 공급되는 공급관(14)이 마련되어 있다.And, one side of the combustion chamber cover 10 is provided with a return pipe 12 for returning water from a heating and hot water pipe (not shown), the other side is heated by the internal heat exchange tube 28 and the heat exchanger 24 to be described later A supply pipe 14 is provided in which hot water is supplied to the heating and hot water pipe again.
상기 연소실커버(10)의 상부에 마련된 배기가스안내판(20)에는 후술할 가스버너(22)에 의해 발생한 배기가스가 외부로 배출되는 배기가스배출공(20a)이 형성되어 있고, 이 배기가스배출공(20a)은 도시 않은 연통에 연결된 후, 배기가스를 외부로 배출시킨다.The exhaust gas guide plate 20 provided above the combustion chamber cover 10 has an exhaust gas discharge hole 20a through which the exhaust gas generated by the gas burner 22 to be described later is discharged to the outside. The ball 20a is connected to a communication (not shown), and then exhausts the exhaust gas to the outside.
상기 연소실(10a) 내의 하부에는 도시가스와 같은 연료에 의해 작동되어 화염을 발생시키는 가스버너(22)가 마련되어 있다.The lower part of the combustion chamber 10a is provided with a gas burner 22 which is operated by a fuel such as city gas to generate a flame.
그리고, 연소실(10a)의 상부에는 열교환기(24)가 마련되어 있고, 이 열교환기(24)는 자세하게 후술할 내부열교환관(28)과 더불어 가스버너(22)에 의해 차가운 물을 온수로 데우는 2차의 열교환 과정을 수행한다.In addition, a heat exchanger 24 is provided at an upper portion of the combustion chamber 10a, and the heat exchanger 24, together with the internal heat exchanger tube 28 which will be described in detail later, is used to heat cold water with hot water by the gas burner 22. Car heat exchange process is carried out.
한편, 전조가공 등에 의해 제조될 수 있는 열교환기(24)는 도 2에 도시된 바와 같이, 동관으로 이루어진 내부에 물이 순환되는 관상의 튜브(24a, Tube)와, 튜브(24a)의 외측에 알루미늄 재질로 이루어진 판면으로부터 반경방향 외측으로 연장된 복수의 열핀(24b, 이를 하이핀(High fin)이라고도 함)을 갖는다.On the other hand, the heat exchanger 24 that can be manufactured by rolling and the like, as shown in Figure 2, the tubular tube (24a, Tube) in which water is circulated inside the copper tube, and the outer side of the tube (24a) It has a plurality of hot fins 24b (also referred to as high fins) extending radially outward from a plate surface made of aluminum.
이와 같이, 튜브(24a)에 열핀(24b)이 전조 가공된 일체의 구성을 소위, 하이핀 튜브(High Finned Tube)라고도 하며, 이러한 하이핀 튜브를 열교환기로 적용함으로써 전열면적이 증가되어 열교환 효율을 현격하게 높일 수 있게 되는 것이다.In this way, the integrated structure in which the hot fin 24b is rolled on the tube 24a is also called a high finned tube. By applying such a high fin tube as a heat exchanger, the heat transfer area is increased to increase heat exchange efficiency. It will be able to increase dramatically.
또한, 하이핀 튜브는 종래와 같이, 전열핀의 별도 생산, 용접하는 등의 공정이 필요하지 않게 되는 바, 그만큼의 원가를 절감시킬 뿐만 아니라 제품을 컴팩트화 시킬 수 있는 요인으로 작용한다.In addition, the high-fin tube does not require a separate process, such as welding, heating fins conventionally, as well as reducing the cost as well as acts as a factor that can compact the product.
이때, 보다 높은 열교환 효율을 얻고자 한다면, 다음과 같이 튜브(24a) 및 열핀(24b)을 제조하는 것이 보다 바람직할 것이다.At this time, if you want to obtain a higher heat exchange efficiency, it would be more preferable to manufacture the tube 24a and the hot fin 24b as follows.
즉, 도 2에 도시된 바와 같이, 내부에 물이 순환되는 관상의 튜브(24a)는 동 재질로 형성하되, 그 내부 두께(C)는 0.2㎜ 내지 5㎜의 범위를 갖도록 제조하는 것이 유리하다.That is, as shown in Figure 2, the tubular tube 24a through which water is circulated is formed of the same material, the inner thickness (C) is advantageously manufactured to have a range of 0.2mm to 5mm. .
그리고, 튜브(24a)의 외측에 전조 가공되는 열핀(24b)은 알루미늄 재질로 형성하되, 열핀(24b)의 높이(A)는 약 8㎜ 이상으로 하고, 두께(B)는 0.2㎜ 내지 10㎜의 범위를 갖도록 제조하는 것이 유리하다.The hot fins 24b rolled on the outside of the tube 24a are made of aluminum, but the height A of the hot fins 24b is about 8 mm or more, and the thickness B is 0.2 mm to 10 mm. It is advantageous to manufacture to have a range of.
이때, 튜브(24a)에 전조 가공되는 알루미늄의 두께는 0.2㎜ 내지 5㎜의 범위를 갖는 것이 보다 효과적일 것이다.At this time, it is more effective that the thickness of the aluminum rolled on the tube 24a has a range of 0.2 mm to 5 mm.
상기 열교환기(24)에는 연결관(26)이 결합되어 있고, 이 연결관(26)은 그 일단이 열교환기(24)와 결합되고 타단은 연소실커버(10)의 내측에 배치된다.A connection pipe 26 is coupled to the heat exchanger 24, and one end thereof is coupled to the heat exchanger 24, and the other end thereof is disposed inside the combustion chamber cover 10.
상기 연소실커버(10) 내측 연결관(26)과 환수관(12) 사이에는 양단이 각각 연결관(26) 및 환수관(12)에 연통되는 내부열교환관(28)이 마련되어 있다.Between the combustion chamber cover 10 inner connection pipe 26 and the return pipe 12, there is provided an internal heat exchange tube 28 in which both ends communicate with the connection pipe 26 and the return pipe 12, respectively.
내부열교환관(28)은 가스버너(22)에 의해 차가운 물을 온수로 데우는 1차의 열교환 과정을 수행한다.The internal heat exchange tube 28 performs a primary heat exchange process of warming cold water with hot water by the gas burner 22.
본 발명에서 내부열교환관(28)은 도시된 바와 같이, 연소실커버(10)의 내벽면을 따라 고리형상으로 복수회 권취되어 있다.In the present invention, as shown, the internal heat exchange tube 28 is wound in a plurality of times in an annular shape along the inner wall surface of the combustion chamber cover 10.
이때, 권취되는 각 측면들은 상호 접촉하지 않도록 함으로써 가스버너(22)의 화염에 의한 그 전열면적이 증가되어 열교환 효율을 보다 높일 수 있도록 하는 것이 바람직할 것이다.At this time, it is desirable that each side of the wound is not in contact with each other so that the heat transfer area by the flame of the gas burner 22 is increased to increase heat exchange efficiency.
이러한 구성에 의하여, 가스버너(22)가 작동된 상태에서 차가워진 물이 환수관(12)을 통해 연소실커버(10) 내로 유입되면, 유입된 물은 내부열교환관(28)의 내부를 따라 유동하는 과정에서 증가된 만큼의 전열면적으로 인해 1차의 열교환 과정이 수행된다.By this configuration, when the cold water is introduced into the combustion chamber cover 10 through the return pipe 12 while the gas burner 22 is operated, the introduced water flows along the inside of the internal heat exchange pipe 28. The primary heat exchange process is performed due to the increased heat transfer area in the process.
1차의 열교환 과정이 수행된 물은 연결관(26)을 통해 열교환기(24)로 향하여 2차의 열교환 과정이 수행된다.The water subjected to the first heat exchange process is subjected to the second heat exchange process toward the heat exchanger 24 through the connection pipe 26.
2차의 열교환 과정이 수행되는 과정에서, 본 발명에 따른 열교환기(24)는 튜브(24a)와, 튜브(24a)의 판면으로부터 반경방향 외측으로 연장된 복수의 열핀(24b, High fin)으로 구성된 소위, 하이핀튜브(High Finned Tube)로 채용되고 각 부분별 사이즈(A ~ C, 도 2 참조)를 상술한 바와 같이, 결정함으로써 열교환 효율은 현격하게 높아진다.In the process of performing the secondary heat exchange process, the heat exchanger 24 according to the present invention includes a tube 24a and a plurality of hot fins 24b (High fins) extending radially outward from the plate surface of the tube 24a. The heat exchange efficiency is significantly increased by adopting a so-called high finned tube configured and determining the size of each part (A to C, see FIG. 2) as described above.
내부열교환관(28) 및 열교환기(24)에 의해 각각 열교환된 물은 공급관(14)을 통해 난방 및 온수배관으로 향하게 된다.The water heat exchanged by the internal heat exchange tube 28 and the heat exchanger 24 respectively is directed to the heating and hot water pipes through the supply pipe 14.
이와 같이, 본 발명에서는 열교환기(24)를 튜브(24a)와, 튜브(24a)의 판면으로부터 반경방향 외측으로 연장된 복수의 열핀(24b, High fin)으로 구성하고 있는 바, 종래와 같이 열교환기(24)를 크게 형성시킬 필요가 없어 제품을 컴팩트화 시킬 수 있다.As described above, in the present invention, the heat exchanger 24 is composed of a tube 24a and a plurality of hot fins 24b (high fins) extending radially outward from the plate surface of the tube 24a. It is not necessary to form a large group 24 can make the product compact.
전술한 실시예에서는, 가스보일러 내에 내부열교환관(28)을 마련하고 있지만, 이러한 내부열교환관(28) 대신, 외부열교환관(미도시)이 마련된 가스보일러에도 본 발명의 사상이 충분히 적용될 수 있을 것이다.In the above-described embodiment, the internal heat exchanger tube 28 is provided in the gas boiler, but the idea of the present invention can be sufficiently applied to a gas boiler provided with an external heat exchanger tube (not shown) instead of the internal heat exchanger tube 28. will be.
이상 설명한 바와 같이 본 발명에 따르면, 동 재질의 튜브 바깥면 쪽에 알루미늄 재질을 이용하면서 이 알루미늄 재질의 외주면에 8㎜이상의 열핀을 형성함으로써, 전열면적을 증가시켜 열교환 효율을 현격하게 높일 수 있는 효과가 있다.As described above, according to the present invention, by using an aluminum material on the outer surface of the copper tube and forming a heat fin of 8 mm or more on the outer circumferential surface of the aluminum material, the effect of increasing the heat transfer area and significantly increasing the heat exchange efficiency is obtained. have.
또한, 본 발명은 제품의 원가를 절감시킬 뿐만 아니라 제품을 컴팩트화시킬 수 있는 효과가 있다.In addition, the present invention has the effect of reducing the cost of the product as well as compact product.
