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.

Integrated heat exchange assembly and an associated method thereof

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.

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.

Electronics chassis and method of fabricating the same

A gas detection system is provided for identifying a gas. The gas detection system includes a sensing module with a hollow chamber enclosed by a chamber housing. Additionally, the sensing module includes an optical sensing fiber positioned within the hollow chamber. The optical sensing fiber includes a gas sensor including a fiber Bragg grating positioned at a grating location along the optical sensing fiber, and a sensing layer affixed to an exterior surface of the optical sensing fiber at the grating location. After the gas is directed into the hollow chamber, the sensing layer and the gas exchange heat energy, based in part on a heat transfer coefficient of the gas. The exchange of the heat energy induces a shift in a Bragg resonant wavelength of the fiber Bragg grating which exceeds a threshold shift required for detection, where the shift is used to identify the gas.
