Description

판형 열교환기의 연결관 구조{Connection Pipe Portion of Heat Exchange Machine of Board Form}Connection Pipe Portion of Heat Exchange Machine of Board Form

본 고안은 여러개의 열교환판을 다층으로 구성하여 양측을 지지프레임으로 고정하고 일측 지지프레임 상하에 연결관을 구성하여 상부의 연결관에 냉.온수나 폐열을 유입시켜 다층의 열교환판으로 순환되게 한다음 하부의 연결관으로 배출 시키면서 열교환을 실시케하는 판형 열교환기의 연결관 구조에 관한 것으로서 이를 좀더 구체적으로 설명하자면 부식이 되지않는 재질(스텐인레스등)로 성형되는 연결관 끝에 부착편을 형성하고 부착편을 이용하여 열교환판의 지지프레임에 연결관이 부착되도록 하므로서 냉.온수를 이용하여 열교환을 실시할 때 금속제로되는 지지프레임의 부식을 방지케하고 연결관이 견고하게 결착되는 판형 열교환기를 얻을수 있도록 한 것이다.The present invention consists of a plurality of heat exchanger plates in multiple layers to fix both sides with a support frame and to form a connection pipe above and below one side of the support frame to inject cold or hot water or waste heat into the upper connection pipe to circulate through the multilayer heat exchanger plate. It relates to the connector structure of the plate heat exchanger that performs heat exchange while discharging to the connector of the lower part. More specifically, it forms and attaches an attachment piece at the end of the connector tube formed of a non-corrosive material (such as stainless steel). By attaching the connecting pipe to the support frame of the heat exchanger plate using a piece, it is possible to prevent corrosion of the support frame made of metal when heat-exchanging using cold and hot water and to obtain a plate heat exchanger in which the connection pipe is firmly fixed. It is.

일반적인 판형 열교환기의 연결관 구조는 첨부도면 도 4에서와 같이 부식이 쉽게되는 일반적인 금속제로 만들어진 지지프레임(30)의 상.하 삽입공(31)에 금속제 연결관(40)을 끼운 후 연결관(40) 끝단을 지지프레임(30)에 용접고정시켜 연결관(40)이 열교환판(50)의 통공(51)과 연통되도록하였다.The connector structure of a general plate heat exchanger is as shown in Fig. 4, after inserting the metal connector 40 in the upper and lower insertion holes 31 of the support frame 30 made of a common metal that is easily corroded, and then the connector tube (40) The end is welded to the support frame 30 so that the connecting pipe 40 communicates with the through hole 51 of the heat exchange plate 50.

그러나 이는 연결관(40)과 지지프레임(30)의 용접부(60)와 지지프레임(30) 외면이 열교환판(50)의 통공(51)내에 위치하기 때문에 냉.온수를 이용하여 열교환을 실시할때 냉.온수가 용접부(60)와 지지프레임(30)의 외면에 직접 접촉하게되고 이로인해 1차로 용접부(60)에 부식이 발생하여 누수와 같은 문제점이 발생함은 물론 용접부(60)의 부식이 연결관(40)과 지지프레임(30)에 전가되어 지지프레임(30)과 연결관(40)의 수명을 단축시키는 결점이 있었으며 그리고 연결관(40)의 부식으로 인해 연결관(40)에 연결되는 냉.온수 급수시스템의 배관에도 부식이 전달하게되어 냉.온수를 오염시키는 문제점도 나타났다.However, since the outer surface of the weld 60 and the support frame 30 of the connection pipe 40 and the support frame 30 is located in the through hole 51 of the heat exchange plate 50, the heat exchange can be performed using cold / hot water. When cold and hot water is in direct contact with the outer surface of the welded portion 60 and the support frame 30, this causes corrosion of the welded portion 60 primarily, causing problems such as leakage, as well as corrosion of the welded portion 60 It was transferred to the connector 40 and the support frame 30 to shorten the life of the support frame 30 and the connector 40, and due to the corrosion of the connector 40 to the connector 40 Corrosion is also transferred to the piping of the cold / hot water supply system, which leads to the problem of polluting the cold / hot water.

본 고안은 위와같이 종래의 판형 열교환기의 연결관에서 나타나는 문제점을 해결하기 위해 연결관을 부식이 되지않는 재질로 성형하면서 금속제의 지지프레임 외면과 용접부가 열교환판의 통공 바깥에 위치되게 끔 판형 열교환기의 연결관 구조를 개량한 것인데 이를 첨부된 도면과 함께 더욱 상세히 설명하면 다음과 같다.The present invention is to solve the problems appearing in the connection tube of the conventional plate heat exchanger as described above plate forming heat exchanger so that the outer surface of the metal support frame and the welded portion is located outside the through hole of the heat exchange plate while forming the connection tube with a non-corrosive material It is an improvement of the structure of the connector of the group and described in more detail with the accompanying drawings as follows.

각각 열교환로가 형성되는 여러개의 열교환판(4)(4')들을 층으로 구성하여 양측을 지지프레임(3)(3')으로 지지하고 일측 지지프레임(3) 상.하부에는 냉.온수기나 난방기등을 연결하는 플랜지(102)가 형성된 연결관(1)을 부착하여 지지프레임(3) 내측에 위치하는 열교환판(4)의 통공(401)과 연통되도록 하는것에 있어서,A plurality of heat exchange plates (4) and 4 ', each having a heat exchange path, are formed in layers to support both sides with support frames (3) and 3'. In attaching a connection pipe 1 having a flange 102 for connecting a heater or the like to communicate with the through hole 401 of the heat exchange plate 4 located inside the support frame 3,

지지프레임(3)의 삽입공(301)에 끼워지는 연결관(1)을 부식이 되지않는 스테인레스등으로 만들되, 그 끝단부에 열교환판(4)의 통공(401) 직경 보다 큰 부착편(101)을 일체로 형성하여 삽입공(301) 내측의 부착공(302)에 안착되도록한 다음 부착편(101)과 부착공(302)의 경계부 둘레를 용접하여 연결관(1)이 고정되도록 하여서된 것이다.The connecting piece 1 inserted into the insertion hole 301 of the support frame 3 is made of stainless steel, which is not corroded, and has an attachment piece 101 larger than the diameter of the through hole 401 of the heat exchanger plate 4 at the end thereof. ) Is integrally formed so as to be seated in the attachment hole 302 inside the insertion hole 301 and then welds around the boundary of the attachment piece 101 and the attachment hole 302 to fix the connecting pipe 1. will be.

또한 지지프레임(3)의 삽입공(301)에 끼워지는 연결관(1)을 삽입공(301) 보다 작게하여 삽입공(301)과 연결관(1) 사이에 공간이 형성되도록 하고 연결관(1)은 삽입공(301)외측 둘레로 방사형으로 배치되어 고정되는 다수개의 결착대(5)로 고정되게 하여서 된 것이다.In addition, the connection tube 1 inserted into the insertion hole 301 of the support frame 3 is smaller than the insertion hole 301 so that a space is formed between the insertion hole 301 and the connection pipe 1 and the connection pipe ( 1) is to be fixed by a plurality of binders (5) that are radially arranged and fixed around the outer side of the insertion hole (301).

이와같이된 본 고안은 지지프레임(3)의 부착공(302)에 안착되면서 용접으로 지지프레임(3)에 부착고정되는 연결관(1)과 지지프레임(3)의 용접부(2) 즉, 부착공(302)과 부착편(101)의 경계부가 열교환판(4)의 통공(401) 바깥부에 위치하므로 열교환판(4)의 통공(401)내에는 부식이되지 않는 연결관(1)의 부착편(101) 외면만이 첨부도면 도 2에서와 같이 노출되므로 냉.온수를 순환시키면서 열교환을 실시 할 때에 냉.온수가 용접부(2)와 지지프레임(3) 외면의 접촉이 방지되어 용접부(2)의 부식을 막을수 있음은 물론 금속제 지지프레임(3)의 부식도 막을수 있게되는 것이다.The present invention as described above is mounted in the attachment hole 302 of the support frame 3, the welding pipe (2), that is, the attachment hole of the connecting pipe (1) and the support frame (3) is fixed to the support frame (3) by welding Since the boundary between the 302 and the attachment piece 101 is located outside the through hole 401 of the heat exchange plate 4, the connection pipe 1 is not corroded in the through hole 401 of the heat exchange plate 4. Since only the outer surface of the piece 101 is exposed as shown in FIG. 2, the cold / hot water is prevented from contacting the outer surface of the welding part 2 and the support frame 3 when performing heat exchange while circulating cold and hot water. In addition to preventing corrosion, the corrosion of the metal support frame 3 can be prevented.

또한 연결관(1)이 지지프레임(3)의 삽입공(301) 외면에 배치 고정되는 다수개의 결착대(5)에 용접 고정하므로 연결관(1)의 결착이 견고하게 되고 또 삽입공(301) 내주와 연결관(1) 외주사이에 어느정도 공간이 있기 때문에 연결관(1)의 고정작업도 용이하게 할수있는 것이다.In addition, since the connection pipe 1 is weld-fixed to a plurality of binding tables 5 arranged and fixed to the outer surface of the insertion hole 301 of the support frame 3, the connection of the connection pipe 1 is firm and the insertion hole 301 is fixed. ) Since there is some space between the inner circumference and the outer pipe (1), the fixing of the connecting pipe (1) can be facilitated.

따라서 본 고안은 상기한 바와같이 연결관(1)과 지지프레임(3)의 부착용접부(2)를 열교환판(4)의 통공(401) 외곽에 위치시키므로서 용접부(2)와 지지프레임(3)의 부식이 방지되게 되어 지지프레임(3)의 수명이 오래가는 판형 열교환기를 얻을수 있는 이점이 있음과 아울러 저가의 금속제로 성형된 지지프레임(3)의 사용이 가능하여 판형 열교환기의 생산원가를 낮출수 있는 장점이 있고, 연결관(1)이 부식되지 않는 재질로 성형되기 때문에 연결관(1)에 연결되는 냉.온수 급수시스템의 배관부식을 막을수 있어 부식으로 인한 냉.온수의 오염을 방지할수 있는 효과가 있게되며 또한 연결관(1)의 고정을 항상 견고하게 유지 시킬수 있는 이점을 가진 유용한 고안인 것이다.Therefore, the present invention places the welding portion 2 and the support frame 3 of the connecting pipe 1 and the support frame 3 as described above outside the through-hole 401 of the heat exchange plate 4, so that the welded portion 2 and the support frame 3 ), Which can prevent the plate heat exchanger that has a long service life of the support frame 3, and can be used for the support frame 3 made of low-cost metal, thereby reducing the production cost of the plate heat exchanger. It has the advantage of lowering, and since the connecting pipe (1) is formed of a material that does not corrode, it can prevent the corrosion of the pipe of the cold and hot water supply system connected to the connecting pipe (1) to prevent contamination of cold and hot water due to corrosion. There is an effect that can be done and is a useful design with the advantage of keeping the connection (1) firmly maintained at all times.
