  • Patent number: 9241425
    Abstract: An angled card cage for improved cooling airflow in front to back airflow products is disclosed. The angled card cage for improved cooling airflow includes a card cage having horizontally mounted circuit cards wherein the card cage is oriented at a non-orthogonal yaw angle relative to the front facing of an equipment rack. The angled card cage for improved cooling airflow provides advantages over systems known in the art by reducing pressure head losses incurred by the cooling air stream.
    Type: Grant

  • Patent number: 8109321
    Abstract: A modular heat sink assembly is disclosed. The heat sink assembly includes a main (larger) heat sink member having one or more voids through the member. The heat sink assembly also includes one or more additional (smaller) heat sink members that fit within the voids of the main heat sink member and are able to move (float) within the voids while thermally connected to main heat sink member. The thermal connection to the main heat sink member may be accomplished by incorporating heat pipes as a bridge between the heat sink members, so that heat spreading, and regulation thereof, occurs over the additional heat sink members and the main heat sink member.
