본 발명은 보일러용 열교환기에 관한 것으로, 더욱 상세하게는 교환기 몸체에 직접 수관을 형성함으로써 열효율이 우수하고, 제조공정의 단순화로 생산성 향상 및 제조원가의 절감을 도모할 수 있도록 한 보일러용 열교환기에 관한 것이다. The present invention relates to a heat exchanger for a boiler, and more particularly, to a heat exchanger for a boiler that is excellent in thermal efficiency by forming a water pipe directly in the body of the exchanger, to improve productivity and reduce manufacturing costs by simplifying the manufacturing process. .

일반적으로 난방 및 온수용으로 사용되는 보일러는 가스, 기름, 연탄 등을 연소시킬 때 발생하는 연소열과 전기히터에 전원을 인가하였을 때 발생하는 열 등을 이용하여 물을 가열하고, 이를 순환펌프를 통해 순환시킴으로써 난방수 및 급탕 온수를 얻게 된다.In general, a boiler used for heating and hot water heats water by using combustion heat generated when burning gas, oil, briquettes, and heat generated when electric power is applied to the electric heater, and through the circulation pump. By circulating, heating water and hot water are obtained.

이와 같은 보일러는 연소시 또는 발열시 물(유체)과의 열교환율을 높이기 위하여 다양한 형태의 열교환기가 장착된다.Such boilers are equipped with various types of heat exchangers in order to increase the heat exchange rate with water (fluid) during combustion or heating.

그러나 종래 열교환기는 연소열과의 열 교환율을 높이기 위하여 연소실 내의 배관을 절곡하거나 핀을 설치하는 등 연소열과의 접촉면적을 넓히기 위한 기술적 구성이 수반되어야 하고, 연소열을 재차 회수하기 위한 기술적 구성이 추가되는바, 그에 따라 제조공정이 복잡할 뿐만 아니라 조립성이 떨어져 제조원가를 낮추는데 한계가 있었다.However, in order to increase the heat exchange rate with the combustion heat, the conventional heat exchanger must be accompanied by a technical configuration for widening the contact area with the combustion heat, such as bending a pipe or installing a fin in the combustion chamber, and adding a technical configuration for recovering the combustion heat again. As a result, not only the manufacturing process is complicated, but also the assembly is poor, and there is a limit in lowering the manufacturing cost.

또한, 종래 열교환기는 탱크 내에 전기히터를 장착하여 물을 가열하였으나 탱크 내로 유입되거나 유출되는 유량 변화에 따라 온수 온도가 유동적이어서 적정온도의 난방수 및 급탕온수를 얻는데 많은 어려움이 있었다. In addition, the conventional heat exchanger was equipped with an electric heater in the tank to heat the water, but there was a lot of difficulty in obtaining the heating water and hot water supply of the appropriate temperature because the hot water temperature is fluid in accordance with the flow rate changes flowing into or out of the tank.

본 발명은 전술한 문제점을 해결하기 위하여 안출(案出)된 것으로, 그 목적은 교환기 몸체에 직접 수관을 형성함으로써 열효율이 우수하고, 제조공정의 단순화로 생산성 향상 및 제조원가의 절감이 가능하며, 열 교환율을 높여 적정온도의 난방수를 얻을 수 있도록 한 보일러용 열교환기를 제공하는 데 있다. The present invention has been devised to solve the above-mentioned problems, the object of which is to form a water pipe directly in the exchanger body is excellent in thermal efficiency, it is possible to improve productivity and reduce manufacturing costs by simplifying the manufacturing process, heat It is to provide a heat exchanger for a boiler to increase the exchange rate to obtain a heating water of the appropriate temperature.
