제 1 도는 본발명에 따른 냉각구조의 기본적 구성을 보이는 개념도.

Claims (6)

  1. 복수의 인쇄회로 기판(printed circuit board)을 수납하여 상하면에 각각 통풍구(vent hole)가 있으며 상호적층(stack)되어 캐비넷(cabinet)안에 설치되는 복수의 셀프 유니트(shelf unit)로 구성된 전자장비용 랙(rack)의 냉각구조에 있어서, 상기 냉각구조가 : 각각 적어도 하나의 팬(fan)을 가지는 팬 유니트를 포함하며, 상기 팬 유니트는 상기 셀프 유니트의 상단에 위치하여 셀프 유니트와 함께 하나의 독립적인 냉각블록(cooling block)을 구성하며, 상기 각 독립 냉각블록에서는, 상기 팬 유니트의 상기 팬이 상기 셀프 유니트를 직선적으로 상하 관통하는 냉각풍(cooling wind)을 산출하는 동시에 상기 팬 유니트의 측면에 있는 통풍구를 통해 공기를 흡입하여, 이 공기를 상기 냉각풍의 유속을 이용, 상기 냉각풍과 혼합시킴으로써, 상기 팬 유니트의 팬으로 상향 송출력을 부가하여 최하단 냉각블록에서 상부 냉각블록으로 상승함에 따라 상기 랙의 전체적으로 상기 냉각풍의 유량(flow rare)이 점차 증가되도록 하는 것을 특징으로 하는 전자장비용 랙의 냉각구조.
  2. 제 1 항에 있어서, 상기 각 팬이 상기 팬 유니트의 프레임의 전방으로부터 상기 프레임에 설치 및 제거할 수 있는 카세트형(cassette type) 팬으로 구성되는 것을 특징으로 하는 전자장비용 랙의 냉각구조.
  3. 제 2 항에 있어서, 상기 팬 유니트의 상기 프레임이 상기 카세트형 팬에 공기를 유도하는 경사안내부(slanted guide portion)를 함께 갖는 지지판(support plate)을 구비하여, 상기 카세트형 팬이 상기 지지판상에 설치되는 것을 특징으로 하는 전자장비용 랙의 냉각구조.
  4. 제 3 항에 있어서, 상기 지지판이 상기 카세트형 팬을 삽입하기 위한 가이드 레일(guide rail)과 상기 카세트형 팬을 고정 및 유지하는 기구를 구비하는 것을 특징으로 하는 전자장비용 랙의 냉각구조.
  5. 제 1 항에 있어서, 최상층의 셀프 유니트 대신에 배출안내판(discharge guide plate)이 설치되고, 상기 배출안내판은 랙을 통과한 냉각공기를 상기 최상층의 셀프 유니트의 상면이 아닌 방향으로 배출하는 것을 특징으로 하는 전자장비용 랙의 냉각구조.
  6. 제 1 항에 있어서, 특정 셀프 유니트의 발열량(heating value)에 따라서는 상기 특정 셀프 유니트의 팬유니트를 생략할 수 있는 것을 특징으로 하는 전자장비용 랙의 냉각구조.
