ABSTRACT:
A system, method, and apparatus for distributing air in a blade server are disclosed. Embodiments may include a rotating damper having a damper door, sliding door, and connecting rod. The damper door may be rotatably attached to a blade server having a plurality of blade slots for receiving blades and may rotate between a blocking position and a flat position, where the damper door impedes air through a blade slot when in the blocking position. The sliding door may move between an open position and a closed position, where the sliding door allows airflow through an air opening while in the open position and blocks airflow through the air opening while in the closed position. A further embodiment may include an extension spring to apply a pulling force to the sliding door and a kick up spring to apply a pushing force to the damper door in the flat position.
