    Abstract: Embodiments promote the maintenance of a designed flow of cooling air through a chassis during the servicing of one or more electronic components contained by the chassis. A top opening created by the removal of server chassis from a rack may be significantly reduced by internal lids that provide access to groups of components. Gaps created by the partial removal of groups of components may be significantly reduced by air dams attached to the components that inhibit the flow of air between the components. And the opening created by the removal of a circuit board may be significantly reduced by a flap configured to cover the opening upon removal of the circuit board. The various embodiments may be used individually or in combination to reduce openings in the chassis that may allow air to flow in paths that negatively affect the designed air flow.

  • Patent number: 8976527
    Abstract: The described embodiment relates generally to the manufacture of display assemblies. More particularly the use of alternative back plates for a display assembly is discussed. By using a printed circuit board (PCB) in lieu of a metal backer heat can be evenly spread across the backer by applying a layer of copper configured to normalize a spread of heat across the printed circuit board. The configuration of the copper layer can be configured based on a tested or simulated heat map that accounts for proximate heat producing elements. The PCB can also advantageously act as an interconnection layer between other electrical components disposed within the electronic device.

  • Patent number: 8953314
    Abstract: A fully-passive, dynamically configurable directed cooling system for a microelectronic device is disclosed. In general, movable pins are suspended within a cooling plenum between an active layer and a second layer of the microelectronic device. In one embodiment, the second layer is another active layer of the microelectronic device. The movable pins are formed of a material that has a surface tension that decreases as temperature increases such that, in response to a temperature gradient on the surface of the active layer, the movable pins move by capillary flow in the directions of decreasing temperature. By moving in the direction of decreasing temperature, the movable pins move away from hot spots on the surface of the active layer, thereby opening a pathway for preferential flow of a coolant through the cooling plenum at a higher flow rate towards the hot spots.
