Abstract:
A system, such as a heat exchange assembly includes a support structure having a recess, a first support end, a second support end, and a support portion extending between the first and second support ends. The support structure further includes a plurality of projections protruding from a portion of a surface of the support structure, corresponding to the support portion. The support structure is a primary heat sink. The heat exchange assembly includes a vapor chamber having a casing and a wick disposed within the casing. The vapor chamber is disposed within the recess and coupled to a surface of the support structure such that the plurality of projections surrounds the vapor chamber. The casing includes a mid projected portion disposed at an evaporator portion of the vapor chamber. The first and second support ends, and the mid projected portion include a non-uniform surface configured to contact the circuit card.
Abstract:
An electronics chassis is provided. The electronics chassis includes a plurality of panels that define an interior space. One panel of the plurality of panels has a composite segment having an internal face and an external face. The electronics chassis further includes a conductive thermal pathway that extends through the panel from the internal face of the composite segment to the external face of the composite segment.
Abstract:
A heat exchange assembly for dissipating heat from a hot component of a circuit card is disclosed. The heat exchange assembly includes a support structure having a first support end, a second support end, and a support portion extending between the first support end and the second support end. The support structure further includes a plurality of first projections protruding from a portion of a surface of the support structure, corresponding to the support portion. Further, the heat exchange assembly includes a vapor chamber having a casing and a wick disposed within the casing. The vapor chamber is coupled to a surface of the support structure.
Abstract:
A synthetic jet driven cooling device includes at least one synthetic jet actuator to generate and project a series of fluid vortices. A manifold coupled to the synthetic jet actuator(s) receives the fluid vortices and generates a primary air stream. An air amplifier connected to the manifold by a connecting pipe receives the primary air stream. The air amplifier includes an air intake oriented perpendicular to the connecting pipe and an air outlet positioned opposite the air intake, with a venturi section positioned between the air intake and air outlet that has a diameter smaller than the air intake diameter. A low pressure region in a center of the venturi section entrains a surrounding air in through the air intake to generate a secondary air stream that combines with the primary air stream to generate a combined air flow that flows through the venturi and exits the air outlet.

Abstract:
A heat transfer device filled with a working fluid, includes a casing and a wick disposed within the casing. The wick includes a first sintered layer, a second sintered layer, and a third sintered layer. The first sintered layer is disposed proximate to an inner surface of the casing and the second sintered layer is disposed on the first sintered layer. The second sintered layer includes a first set of 3-dimensional sintered projections and a second set of 3-dimensional sintered projections disposed along a portion of the wick. Further, the third sintered layer is disposed on at least a portion of the second sintered layer. The heat transfer device includes at least one first sintered particle of the first sintered layer, which is smaller in size than at least one second pore of the second sintered layer.
