본 발명은 가스보일러의 열교환기에 관한 것으로, 보다 상세하게는 난방수가 흐르는 난방수유입관을 열교환기 내부에 설치하고 하우징에는 단열부재를 구비하여더 많은 열교환이 열교환기 내부에서 이루어지도록 하는 가스보일러의 열교환기에 관한 것이다.The present invention relates to a heat exchanger of a gas boiler, and more particularly, to install a heating water inlet pipe through which a heating water flows, and to provide a heat insulating member in a housing so that more heat exchange occurs in the heat boiler. It is about the flag.
일반적으로 가스보일러는 가스를 연료로 하여 연소시킬 때 발생하는 연소열을 이용하여 물을 가열하고, 가열되어 축열된 물을 순환펌프를 사용하여 실내에 설치되어 있는 난방배관으로 순환시켜 실내를 난방하게 되며, 아울러 데워진 물을 욕실과 부엌 등에 온수로 공급하는 장치이다.In general, a gas boiler heats water using combustion heat generated when gas is burned as fuel, and heats the heated and regenerated water to a heating pipe installed indoors using a circulation pump to heat the room. In addition, it is a device that supplies hot water to the bathroom and kitchen.
이러한 가스보일러는 제어방식이나 밀폐상태에 따라 여러 가지 형식으로 나눌 수 있으며, 그 밖에도 난방수를 가열하는 열원에 따라 콘덴싱과 비콘덴싱 방식으로 구분할 수 있다.Such gas boilers can be divided into various types according to the control method or the sealed state, and can be classified into condensing and non-condensing methods according to heat sources for heating the heating water.
이 중에서 콘덴싱 방식은 버너에 의해 연소된 열을 이용하여 직접적으로 난방수를 가열하는 현열부 열교환기와 함께, 현열부 열교환기를 통과한 배기가스의 잠열을 이용하여 난방수를 가열하는 잠열부 열교환기를 지니고 있으며, 비콘덴싱 방식은 현열부 열교환기만 구비하고 있다.Among them, the condensing method has a sensible heat exchanger that directly heats the heating water by using the heat burned by the burner, and a latent heat exchanger that heats the heating water by using latent heat of exhaust gas passing through the sensible heat exchanger. In the non-condensing method, only the sensible heat exchanger is provided.
도 1은 종래 일반적인 가스보일러 열교환기의 측면 내부구성도이다.1 is a side internal view of a conventional gas boiler heat exchanger.
도시된 바와 같이, 열교환기(10)의 하단에는 난방수유입구(20)를 통해 공급되는 난방수가 유입되는 난방수유입관(25)이 열교환기(10)의 하우징(15)에 권선되어 있고, 열교환기(10)의 내부에는 열교환을 위해 상기 난방수유입관(25)과 연결되는 현열교환파이프(30)가 구비되어 있으며, 상기 현열교환파이프(30)의 끝단에는 흡열한 난방수가 배출되는 난방수유출부(40)가 형성되어 있다.As shown, at the bottom of the heat exchanger 10, a heating water inlet pipe 25 through which the heating water supplied through the heating water inlet 20 is introduced is wound around the housing 15 of the heat exchanger 10, Inside the vessel 10 is provided with a sensible heat exchange pipe 30 is connected to the heating water inlet pipe 25 for heat exchange, the end of the sensible heat exchange pipe 30 is discharged heating water discharged heating water The part 40 is formed.
이 때, 상기 현열교환파이프(30)의 외부에는 열교환 효율을 높이면서 상기현열교환파이프(30)의 변형을 억제하기 위하여 다수의 현열핀(fin:35)이 경납용접 (braze welding)되어 있다.At this time, a plurality of sensible heat fins (fin) 35 are braze welded to the outside of the sensible heat exchange pipe 30 to increase the heat exchange efficiency and to suppress deformation of the sensible heat exchange pipe 30.
그리고, 상기 열교환기(10)의 하부에는 유입된 공기를 연소시키는 버너(미도시)가 구비되어 가스연료를 연소시키게 된다.And, a lower portion of the heat exchanger 10 is provided with a burner (not shown) for burning the introduced air to burn the gas fuel.
상기와 같은 구성으로 이루어지는 종래 기술에 따른 가스보일러의 동작을 설명하면 다음과 같다.Referring to the operation of the gas boiler according to the prior art having the configuration as described above are as follows.
보일러의 작동시, 유입되는 공기에 의해서 가스가 연소되면 연소열은 열교환기(10) 내부로 전달되며, 열교환기(10)의 하우징(15)에 권선된 난방수유입관(25)을 흐르는 난방수를 예열한 후, 현열교환파이프(30)에서 직접적으로 난방수를 가열하고, 연소된 배기가스는 대기 중에 방출된다.In the operation of the boiler, when the gas is burned by the incoming air, the combustion heat is transferred into the heat exchanger 10, and the heating water flowing through the heating water inlet pipe 25 wound around the housing 15 of the heat exchanger 10. After preheating, the heating water is heated directly in the sensible heat exchange pipe 30, and the burned exhaust gas is discharged to the atmosphere.
그러나, 종래의 열교환기(10)는 난방수가 유입되는 난방수유입관(25)을 열교환기(10)의 하우징(15)의 외부에 권선하여 설치하였기 때문에 열교환기(10)의 하우징(15)에 전달되는 열원 및 외부로 방출되는 열원을 부분적으로만 흡수할 수 있었고, 열교환기(10)의 외관이 복잡하게 형성되어 열교환기(10)의 소형화 및 콤팩트화를 달성하는 데에 문제점이 있었다.However, since the conventional heat exchanger 10 is installed by winding the heating water inflow pipe 25 through which the heating water flows to the outside of the housing 15 of the heat exchanger 10, the heat exchanger 10 may be installed in the housing 15 of the heat exchanger 10. The heat source to be transferred and the heat source discharged to the outside were only partially absorbed, and the external appearance of the heat exchanger 10 was complicated, resulting in a problem of achieving miniaturization and compactness of the heat exchanger 10.
또한, 상기 난방수유입관(25)의 흡열을 위하여 열교환기(10)를 단열할 수 없어 전체적으로 열교환기(10)의 효율이 떨어지는 문제점이 있었다.In addition, the heat exchanger 10 cannot be insulated for the endothermic heat of the heating water inflow pipe 25, so that the efficiency of the heat exchanger 10 is lowered as a whole.
이에 본 발명은 상기와 같은 문제점들을 해소하기 위해 안출된 것으로써, 본발명의 목적은 난방수가 유입되어 흐르는 난방수유입관을 열교환기의 외부가 아닌 내부에 설치하고 열교환기의 하우징에는 단열부재를 구비함으로써, 전열면적은 크게 하고 외부로 열이 방출되어 낭비되는 것은 방지하여 더욱 많은 열이 열교환기 내부에서 교환되도록 하면서, 장치의 소형화 및 콤팩트화를 확보하는 가스보일러의 열교환기를 제공하는 데 있다.Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to install a heating water inlet pipe flowing in the heating water flows in the interior of the heat exchanger, not the outside, and the heat exchanger housing is provided with a heat insulating member Accordingly, the present invention provides a heat exchanger of a gas boiler that increases the heat transfer area and prevents heat from being discharged to the outside, thereby allowing more heat to be exchanged inside the heat exchanger, while ensuring miniaturization and compactness of the device.

도시된 바와 같이 본 발명에 따른 가스보일러의 열교환기는 종래기술과 연계하여, 유사한 구성의 열교환기(10)의 하우징(15)에 권선 형성되어 난방수유입구 (20)를 통해 난방수를 유입하는 난방수유입관(25)과, 상기 난방수가 유동하면서 버너에 의한 연소열을 이용하여 직접적으로 열교환하는 현열교환파이프(30)와, 상기 현열교환파이프(30)에 부착되어 전열면적을 넓히기 위해 구비된 현열핀(35)과, 상기 현열교환파이프(30)를 통해 가열된 난방수가 배출되는 난방수유출부(40)를 포함하여 구성된다.As shown, the heat exchanger of the gas boiler according to the present invention is connected to the prior art, the winding is formed in the housing 15 of the heat exchanger 10 of a similar configuration to the heating water flowing through the heating water inlet 20 A sensible heat exchange pipe 30 for directly exchanging heat by using combustion heat by a burner while the water inlet pipe 25 and the heating water flow, and a sensible heat fin attached to the sensible heat exchange pipe 30 to increase the heat transfer area. 35 and a heating water outlet 40 through which the heating water heated by the sensible heat exchange pipe 30 is discharged.
이하, 본 발명에 따른 가스보일러의 열교환기는 비콘덴싱 방식의 가스보일러에 한정하지 아니하고, 콘덴싱 방식의 가스보일러에도 해당한다.Hereinafter, the heat exchanger of the gas boiler according to the present invention is not limited to the non-condensing gas boiler, but also corresponds to the condensing gas boiler.
여기서 본 발명의 요지구성은, 상기 열교환기(10)의 하우징(15)에 단열부재 (45)를 구비하고, 열교환기(10)의 외부에 권선된 난방수유입관(25)을 상기 열교환기(10)의 내부에 형성되도록 구성한 것이다.The gist configuration of the present invention is provided with a heat insulating member 45 in the housing 15 of the heat exchanger 10, and the heating water inlet pipe 25 wound around the outside of the heat exchanger 10 to the heat exchanger ( It is configured to be formed inside the 10).
이하, 상기와 같은 구성으로 이루어진 본 발명에 의한 가스보일러의 열교환기의 작용 및 효과를 설명하면 다음과 같다.Hereinafter, the operation and effects of the heat exchanger of the gas boiler according to the present invention having the above configuration will be described.
외부로부터 유입되는 공기를 이용하여 상기 버너에서 가스가 연소되면 연소열은 열교환기(10) 내부로 전달되며, 열교환기(10)의 내벽에 형성되어 난방수를 유입하는 난방수유입관(25)에서 난방수가 예열된다.When gas is burned in the burner using air introduced from the outside, combustion heat is transferred into the heat exchanger 10, and is formed in the inner wall of the heat exchanger 10 to be heated in a heating water inlet pipe 25 that introduces heating water. The number is preheated.
이어서, 상기 난방수는 현열교환파이프(30)를 지나면서 직접적으로 가열되어 난방수는 축열한 후, 난방수유출부(40)를 통해 배출되며, 연소된 배기가스는 대기 중에 방출된다.Subsequently, the heating water is directly heated while passing through the sensible heat exchange pipe 30 so that the heating water is regenerated and discharged through the heating water outlet 40, and the burned exhaust gas is discharged into the atmosphere.
이 때, 상기 열교환기(10)의 내부에서는 단열부재(45)에 의한 단열에 의하여보다 많은 열교환이 이루어지게 된다.At this time, more heat exchange is made in the heat exchanger 10 by heat insulation by the heat insulating member 45.
또한, 상기 난방수유입관(25)이 열교환기(10)의 외부가 아닌 내부에 구비되므로, 종래의 열교환기(10)의 하우징(15)에 의해 방사되던 열을 일측으로만 받아 예열되던 난방수유입관(25)은 전열면적을 넓혀 흡열할 수 있게 된다.In addition, since the heating water inflow pipe 25 is provided not in the outside of the heat exchanger 10, the heating and feeding is preheated by receiving only one side of the heat radiated by the housing 15 of the conventional heat exchanger 10. The entrance tube 25 is able to absorb heat by increasing the heat transfer area.
상기 난방수유입관(25)이 열교환기(10)의 내부로 구비됨에 따라, 외부로 권선되어 차지하던 부피를 보상받게 되므로, 상기 열교환기(10)는 소형화되고, 외관이 정비되어 컴팩트화를 이룰 수 있게 된다.As the heating water inflow pipe 25 is provided inside the heat exchanger 10, the volume of the heating water inlet 25 is compensated for being wound outside, and thus the heat exchanger 10 is miniaturized and the appearance is maintained to achieve compactness.

이상에서, 상기 열교환기(10)는 일반적인 가스보일러의 것으로 예시 및 도시하였으나, 본 발명의 목적은 난방수유입관(25)을 열교환기(10)의 내부에 형성하고, 열교환기(10)의 하우징(15)에 단열부재(45)를 구비하여 열전달 효율을 높이는 것에 있다.In the above, although the heat exchanger 10 is illustrated and illustrated as that of a general gas boiler, an object of the present invention is to form a heating water inlet pipe 25 in the heat exchanger 10, the housing of the heat exchanger 10 The heat insulating member 45 is provided in 15, and heat transfer efficiency is improved.
그러므로, 상기와 같은 구성에 한정하지 않고 본 발명의 사상 및 영역으로부터 벗어나지 않는 범위 내에서 다양하게 수정 및 변경시킬 수 있음을 당업자라면 인지할 수 있을 것이다.Therefore, those skilled in the art will recognize that various modifications and changes can be made without departing from the spirit and scope of the present invention without being limited to the above-described configuration.
상기한 바와 같이 본 발명에 따른 가스보일러의 열교환기에 의하면, 난방수가 유입되어 흐르는 난방수유입관을 열교환기의 외부가 아닌 내부에 설치하고 열교환기의 하우징에는 단열부재를 구비함으로써, 전열면적은 크게 하고 외부로 열이 방출되어 낭비되는 것은 방지하여 더욱 많은 열이 열교환기로 흡수되도록 하면서장치의 소형화 및 콤팩트화를 이루는 매우 유용하고 효과적인 발명이다.As described above, according to the heat exchanger of the gas boiler according to the present invention, the heating water inflow pipe in which the heating water flows is installed inside the heat exchanger, not the outside of the heat exchanger, and the heat exchanger housing is provided with a heat insulating member to increase the heat transfer area.
