Plate Fins for Finned Tube Heat Exchangers

본 발명은 목적은 냉/난방 또는 냉장/냉동기 등에 적용되는 열교환기, 즉 플레이트핀을 사용하도록 된 핀튜브형 열교환기의 핀 플레이트를 제공함에 의해 달성되게 되는데, 이 핀플레이트는 열전도성이 우수한 금속박판재를 장방형상의 평판체로 재단하여 그 면에 기류방향과 교차하는 수직방향으로 적합한 프레스공정을 통해 경사부와 수평부로 이루어지는 수열의 핀을 등간격으로 구비하여 전열관의 삽입안내와 간격유지를 위해 설치되는 핀칼라을 빗겨 핀칼라 사이사이로 핀군이 구비되어 있다. 이러한 핀군은 플레이트핀의 전후면에 인접한 핀과 서로 반대방향으로 이루며, 그리고 이러한 핀의 경사부를 기류방향과 병행하는 핀칼라의 수평중심선방향에서 그 수평중심선을 넘지않는 이내의 유동접선에서 기류 유입측은 핀칼라의 원호접점에서 다소 떨어지고 기류 유출측은 유입측 보다는 원호접점에 근접되게 적당히 배열하여 핀칼라의 후방부로 부하 없이 선회하는 기류를 발생시키어 가능한 핀칼라 후방의 사영역을 줄이게 하고 있다. 핀은 또한 기류 유입측 보다는 유출측에 밀도를 높게 가지어 전면적으로 풍속을 균등하게 구성하고 있다. 따라서 핀칼라 후방 기류의 사영역을 줄이고, 유출기류의 풍속분포를 균일학 하여 소음발생을 가능한 저감하며, 열교환능력을 향상시키어 제품성을 높이게 된다.
