가스기기용 열교환 파이프 연결구조{heat exchange pipe coupling structure for gas appliances}Heat exchange pipe coupling structure for gas appliances

본 고안은 가스기기용 열교환 파이프 연결구조에 관한 것으로, 더 상세하게는 가스기기용 열교환기의 열교환 파이프와 상호 접속되는 연결파이프의 직경을 열교환 파이프 직경보다 작게 형성한 후 고정시켜 연결작업의 편의성을 향상시킬 수 있도록 고안된 것이다.The present invention relates to a heat exchange pipe connection structure for gas appliances, and more particularly, the diameter of the connection pipes interconnected with the heat exchange pipes of the heat exchanger for gas appliances is smaller than the diameter of the heat exchange pipe and then fixed to facilitate the connection work. It is designed to improve.

일반적으로, 열교환기는 가스나 기름을 연료로 사용하는 버너를 통해 가열되어 그 내부로 공급되는 물을 원하는 온도로 가열시킨 후 난방 및 급탕에 필요한 물로 전환하는 것으로, 대부분의 열교환기는 소정 용적을 갖도록 제작된 사각함체내에 수개의 흡열판들을 적층 형태로 배치하고, 이들 흡열판에 직교방향으로는 그 내부로 수개의 파이프를 설치하되, 이 파이프로 난방수 또는 온수가 흐르도록 형성하고, 상기 열교환기의 저부로는 버너가 설치되는 구성으로 되어 있다.In general, the heat exchanger is heated through a burner that uses gas or oil as a fuel to heat the water supplied therein to a desired temperature and then convert it into water for heating and hot water supply. Most heat exchangers are manufactured to have a predetermined volume. A plurality of heat absorbing plates are arranged in a stacked form in a rectangular box, and several heat sinks are installed in the heat absorbing plates in an orthogonal direction, and the heating water or hot water flows through the pipes, and the heat exchanger At the bottom, the burner is installed.

그리고, 열교환기의 열교환 파이프와 연결되어 난방수 및 온수가 흐를 수 있도록 하는 연결파이프와 열교환 파이프의 연결구조는 열교환 파이프의 접속부위를 확관시켜, 열교환 파이프와 동일한 직경의 연결파이프를 접속한 후 용접하여 고정시키고 있다.In addition, the connection structure of the connection pipe and the heat exchange pipe connected to the heat exchange pipe of the heat exchanger to allow the heating water and hot water to flow, expands the connection portion of the heat exchange pipe, connects the connection pipes of the same diameter as the heat exchange pipe, and then welds them. Is fixed.

또한, 이때 열교환기의 몸체는 도 2에서 도시한 바와 같이 내측으로 절곡시켜 열교환 파이프의 확관부와 걸려지도록 구성한다.In addition, the body of the heat exchanger is bent inward as shown in Figure 2 is configured to be caught with the expansion portion of the heat exchange pipe.

또, 열교환 파이프와 열교환기 몸체의 접합부에는 밀폐력 및 누수를 방지할 수 있도록 실링재를 장착하여 사용하고 있다.In addition, the sealing portion is attached to the heat exchanger pipe and the heat exchanger body so as to prevent the sealing force and leakage.

상기와 같이 종래 가스기기용 열교환기의 열교환 파이프와 연결파이프의 접속구조는 상호 동일한 직경을 사용하는 관계로, 열교환 파이프의 접속부를 확관시킨 후 연결파이프를 끼워 용접에 의해 고정시키는 방식이므로, 접속을 위한 공정수가 증대되어 작업 생산성 및 편의성이 저하되는 문제점이 있었다.Since the connection structure of the heat exchange pipe and the connection pipe of the heat exchanger for a conventional gas appliance uses the same diameter as each other, the connection part of the heat exchange pipe is expanded, and the connection pipe is inserted to fix the connection. There was a problem in that the number of processes for increase work productivity and convenience decrease.

또한, 연결파이프를 열교환 파이프에 접속한 후에는 밀폐력 및 누수방지를 위하여 실링재를 열교환기 몸체와 열교환 파이프의 접속부위에 장착하므로, 생산 코스트가 상승되는 폐단이 있었던 것이다.In addition, after connecting the connecting pipe to the heat exchange pipe, the sealing material is mounted on the connection portion between the heat exchanger body and the heat exchange pipe in order to prevent the sealing force and leakage, there is a closed end that the production cost is increased.

본 고안의 목적은 가스기기용 열교환기의 열교환 파이프와 상호 접속되는 연결파이프의 직경을 열교환 파이프 직경보다 작게 형성한 후 고정시켜 연결작업의 편의성을 향상시킬 수 있도록 한 가스기기용 열교환 파이프 연결구조를 제공하는 데 있다.The purpose of the present invention is to provide a heat exchange pipe connection structure for a gas appliance that can improve the convenience of the connection work by forming and fixing the diameter of the connection pipe interconnected with the heat exchange pipe of the heat exchanger for the gas appliance smaller than the diameter of the heat exchange pipe. To provide.

본 고안의 다른 목적은 제품의 신뢰성 및 내구성을 향상시킬 수 있도록 한 가스기기용 열교환 파이프 연결구조를 제공하는 데 있다.Another object of the present invention is to provide a heat exchange pipe connection structure for a gas machine to improve the reliability and durability of the product.

이러한 본 고안의 목적은, 열교환기(10)의 내부에 위치되어 난방수 및 온수가 순환될 수 있도록 형성되는 열교환 파이프(11)와;An object of the present invention, the heat exchange pipe 11 is formed inside the heat exchanger 10 so that the heating water and hot water can be circulated;

상기 열교환 파이프(11)의 외측 고정부(12)에 설치되어 각각의 열교환 파이프(11)를 상호 연결시키는 연결파이프(20)와;A connection pipe 20 installed at an outer fixing part 12 of the heat exchange pipe 11 to interconnect each heat exchange pipe 11;

상기 열교환 파이프(11)와 연결파이프(20)상호 접속 고정시키는 연결수단(30)으로 구성된 것에 있어서;In the heat exchange pipe (11) and the connection pipe (20) consisting of connecting means (30) for mutual connection fixing;

상기 연결수단(30)은 열교환 파이프(11)의 고정부(12) 확관작업과 실링재의 장착없이 연결시킬 수 있도록, 열교환 파이프(11)의 내경 크기로 연결파이프(20)를 형성하여 삽입하고, 열교환 파이프(11)의 상부에는 열교환기(10) 접속부(13)를 외측으로 절곡시킨 후 외측 단부면(31)을 용접하여 달성된다.The connecting means 30 is formed by inserting the connecting pipe 20 to the inner diameter of the heat exchange pipe 11 so as to be connected to the expansion of the fixing portion 12 of the heat exchange pipe 11 without mounting the sealing material, The upper part of the heat exchange pipe 11 is achieved by bending the heat exchanger 10 connection portion 13 outward and then welding the outer end surface 31.

따라서, 본 고안인 가스기기용 열교환 파이프 연결구조는 열교환 파이프(11)의 내경 크기로 연결파이프(20)를 형성하여 삽입하고, 열교환기(10) 몸체 접속부(13)를 열교환 파이프(11)의 상부로 위치되게, 절곡시킨 후 외측 단부면(31)을 용접시켜 연결시키므로, 종래와 같이 열교환 파이프(11)의 고정부(12) 확관작업과, 별도의 씰링재(50)의 설치없이 연결작업을 수행할 수 있는 것이다.Therefore, the heat exchange pipe connection structure for a gas appliance according to the present invention forms and inserts a connection pipe 20 to the inner diameter of the heat exchange pipe 11, and inserts the heat exchanger 10 body connection portion 13 into the heat exchange pipe 11. Since the outer end surface 31 is welded and connected after being bent to the upper position, the expansion work of the fixing part 12 of the heat exchange pipe 11 and the connection work without the installation of a separate sealing material 50 are performed as in the prior art. It can be done.

그러므로, 작업의 편의성 및 제품의 신뢰성을 향상시킬 수 있는 것이다.Therefore, the convenience of work and the reliability of the product can be improved.

이하, 본 고안의 바람직한 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention in detail as follows.

도 1은 종래 보일러의 열교환 파이프 연결구조를 도시한 정면도이다.1 is a front view showing a heat exchange pipe connection structure of a conventional boiler.

도 2는 종래 열교환 파이프의 연결구조를 도시한 요부 확대 단면도이다.2 is an enlarged cross-sectional view illustrating main parts of a conventional heat exchange pipe connecting structure.

도 3은 본 고안인 열교환 파이프 연결구조를 요부 확대 단면도로 도시하고 있다.Figure 3 shows the heat exchange pipe connection structure of the present invention in an enlarged sectional view of the main portion.

즉, 도 1 ∼ 도 3에서 도시한 바와 같이 본 고안인 가스기기용 열교환 파이프 연결구조는 열교환 파이프(11)의 고정부(12) 확관작업과 씰링재(50)의 설치없이 연결작업을 수행할 수 있도록, 열교환 파이프(11)의 내경 크기로 연결파이프(20)를 형성하여 상호 접속시킨다.That is, as shown in Figures 1 to 3, the heat exchange pipe connection structure for a gas appliance according to the present invention can perform the connection work without expanding the fixing portion 12 of the heat exchange pipe 11 and the installation of the sealing material 50. In order to connect the pipes 20 to each other, the connecting pipes 20 are formed to have an inner diameter of the heat exchange pipe 11.

그리고, 상기 열교환 파이프(11)와 연결파이프(20)의 접속은 억지키움 방식으로 삽입하여 접속시키는 것이 바람직하다.In addition, the connection between the heat exchange pipe 11 and the connection pipe 20 is preferably inserted into and connected by an interference raising method.

따라서, 상기 연결파이프(20)의 직경은 열교환 파이프(11)의 내경 크기보다 미세한 크기로 다소 크게 설정한 후 억지끼움 방식에 의해 고정시키므로, 누수방지와 밀폐력을 향상시킬 수 있는 것이다.Therefore, since the diameter of the connecting pipe 20 is set to be slightly larger than the size of the inner diameter of the heat exchange pipe 11 and fixed by the interference fit method, leakage prevention and sealing force can be improved.

한편, 상기 연결파이프(20)가 내측으로 삽입된 열교환 파이프(11)의 몸체 상부로는 열교환기(10) 몸체 접속부(13)가 외측으로 절곡되어 위치된다.On the other hand, the heat exchanger 10 body connection portion 13 is bent outward to the upper portion of the body of the heat exchange pipe 11 into which the connection pipe 20 is inserted.

상기 열교환기(10)의 몸체 접속부(13)가 외측으로 절곡되는 이유는 종래와 같이 별도의 씰링재(50)를 설치하 않고 상호 연결작업을 수행할 수 있도록 외측으로 절곡시키는 것이다.The reason why the body connection part 13 of the heat exchanger 10 is bent to the outside is to be bent outward so that the interconnection work can be performed without installing a separate sealing material 50 as in the related art.

이는, 열교환기(10) 몸체 접속부(13)를 열교환 파이프(11)의 상부 즉, 외측으로 절곡시켜, 열교환 파이프(11)와 밀착시킨 후 외측의 단부면(31)을 용접하여 연결작업을 수행하는 것이다.This is, by bending the heat exchanger (10) body connecting portion 13 to the upper portion of the heat exchange pipe 11, that is, the outside, in close contact with the heat exchange pipe (11) and welding the end surface 31 of the outside to perform the connection work It is.

따라서, 상기와 같이 열교환기(10) 몸체 접속부(13)를 외측으로 절곡시켜, 열교환 파이프(11)의 상부면에 위치되도록 한 후 외측 단부면(31)을 용접하므로, 열교환 파이프(11)의 고정부(12)와 열교환기(10) 몸체 접속부(13), 연결파이프(20) 상부면의 상호 접합면(40)을 용접하므로, 종래와 같이 열교환 파이프(11)의 확관작업과 별도의 씰링재(50)의 설치없이 연결작업을 수행할 수 있는 것이다.Therefore, as described above, the heat exchanger 10 body connection part 13 is bent outward so as to be positioned on the upper surface of the heat exchange pipe 11, and then the outer end surface 31 is welded. Since the fixing part 12, the heat exchanger 10 body connection part 13, and the joint surface 40 of the upper surface of the connection pipe 20 are welded, the sealing material separate from the expansion work of the heat exchange pipe 11 as in the prior art. Connection can be performed without the installation of (50).

한편, 상기와 같이 단부면(31)에 용접작업 후에는 용접액이 열교환기 몸체 쪽으로 흘러내려 씰링이 동시에 이루어지므로, 별도의 씰링재(50)의 설치없이 밀폐력 및 누수방지 효과를 볼 수 있는 것이다.On the other hand, after the welding operation to the end surface 31 as described above, since the welding liquid flows down to the heat exchanger body to seal at the same time, it is possible to see the sealing force and leakage prevention effect without the installation of a separate sealing material (50).

그러므로, 본 고안인 가스기기용 열교환 파이프 연결구조는 열교환 파이프(11)의 확관작업과 별도의 씰링재(50)의 설치없이 연결파이프(20)를 접속시켜 사용할 수 있으므로, 작업 편의성 및 생산성을 향상시킬 수 있는 것이다.Therefore, the heat exchange pipe connection structure for the gas appliance according to the present invention can be used by connecting the connection pipe 20 without the expansion work of the heat exchange pipe 11 and the installation of a separate sealing material 50, thereby improving work convenience and productivity. It can be.

상기와 같은 본 고안의 구성에 의하면, 종래의 가스기기용 열교환 파이프 연결구조와 달리 열교환 파이프의 확관작업과 별도의 씰링재의 설치없이 연결작업을 수행할 수 있으므로, 별도의 작업공정이 축소되어 작업 생산성 및 편의성을 향상시킬 수 있는 것이다.According to the configuration of the present invention as described above, unlike the conventional heat exchange pipe connection structure for gas appliances can be performed without the expansion work of the heat exchange pipe and the installation of a separate sealing material, the separate work process is reduced and work productivity And convenience can be improved.

그러므로, 제품의 신뢰성 및 내구성을 향상시킬 수 있는 매우 유용한 고안인 것이다.Therefore, it is a very useful design that can improve the reliability and durability of the product.
