본 고안은 가스용 판형열교환기(1)에 관한 것으로 더욱 상세하게는 고온가스와 저온공기가 적층된 전열판(2)에 의해 열교환이 이루어지는 가스용 판형열교환기에서 고온가스에 의한 전열판(2)의 열팽창길이와 사이드판넬(3) 및 코너빔(4)과의 열팽창길이 편차에 의한 모서리부분 용접, 연결부에 균열(Crack)발생을 방지하도록 보강하는 구조에 관한 것이다.The present invention relates to a plate heat exchanger (1) for gas, and more particularly, to a plate heat exchanger (2) by hot gas in a gas plate heat exchanger in which heat is exchanged by a heat transfer plate (2) in which hot gas and low temperature air are laminated. The present invention relates to a structure for reinforcing to prevent cracking at the edge portion welds and joints due to the thermal expansion length and the thermal expansion length deviation between the side panel 3 and the corner beams 4.

판형 열교환기를 사용하여 고온의 가스를 열교환 할시 열교환이 이루어지는 전열판(2)의 열팽창이 상당히 크기 때문에 상대적으로 열팽창이 적은 사이드판넬(3) 및 코너빔(4)과의 용접된 연결부위에서 균열현상이 발생될 수 있다. 이러한 문제로 인하여 종래의 가스용 판형열교환기는 고온가스에 적용하기 어려웠거나 전열판과 사이드판넬 및 코너빔 연결을 용접대신 가스켓을 삽입하여 제작하기도 하였으나 이 구조는 누설가스의 양이 많고 전열면의 변형을 발생시키는 단점이 있다. 또한 전열판 자체에 물결모양의 굴곡을 주어 열팽창을 흡수하는 구조로 제작하기도 했으나 이 구조는 전열판과 전열판사이의 간격을 유지시키기 어려워 열교환시 심한 진동으로 인해 소음 및 전열판의 변형을 발생시키며 유로의 불균일성으로 인해 차압이 상승하며 부분적인 부식이 발생된다. 또한 가스성분중 먼지등의 더스트가 포 함되어 있을 경우 청소가 어렵다는 단점이 있다.When heat exchanges high temperature gas using a plate heat exchanger, the thermal expansion of the heat exchanger plate 2, which undergoes heat exchange, is considerably large, so that a crack occurs in the welded connection portion of the side panel 3 and the corner beam 4 having relatively low thermal expansion. Can be. Due to these problems, the conventional plate heat exchanger for gas was difficult to be applied to hot gas, or the plate plate and side panel and corner beam connection were manufactured by inserting a gasket instead of welding, but this structure has a large amount of leakage gas and deforms the heat transfer surface. There is a disadvantage. In addition, it was manufactured as a structure that absorbs thermal expansion by giving wavy curves to the heat transfer plate itself, but it is difficult to maintain the gap between the heat transfer plate and the heat transfer plate, which causes noise and deformation of the heat transfer plate due to severe vibration during heat exchange, As a result, the differential pressure rises and partial corrosion occurs. In addition, there is a disadvantage that the cleaning is difficult when dust, such as dust in the gas components.
