An apparatus includes a heat exchanger configured to be positioned around and coupled to a multi-axis gimbal. The heat exchanger includes an inlet configured to receive fluid containing heat generated by an equipment package carried by the gimbal. The heat exchanger also includes multiple heat rejection interfaces configured to reject the heat from the fluid into surrounding air in order to cool the fluid. The heat exchanger further includes an outlet configured to provide the cooled fluid from the heat exchanger. The heat rejection interfaces of the heat exchanger extend around the heat exchanger and are configured to reject the heat from the fluid regardless of a direction in which the gimbal is pointing the equipment package.

An airborne substance detector includes an air intake that sweeps through a fixed area, and a fan that draws air toward an effluence detection device that analyzes the air for one or more substances, such as explosives. The air intake may be a series of tubes of a rotary gate, with multiple sets of tubes that rotate about a central axis. The fan or blower draws air through holes in the tubes, and through a manifold that directs air to the effluence detection device from a single set of tubes at a time. In addition the detector may include a heater that may enhance vaporization of substances to be detected. The effluence detection device, the manifold, and the fan may be located in an enclosure at the top of the rotary gate. After detection, a decontamination procedure may be initiated to purge the system of the substance that was detected.

An apparatus, system and method for multi-orientation single or two phase coldplate with positive flow characteristics is disclosed. In representative embodiments and applications, the present invention generally provides improved methods and systems for cooling through fluid cooled coldplates.

Multi-orientation single or two phase coldplate with positive flow characteristics

An apparatus includes a thermally conductive section with a side facing approximately parallel to an axis and adapted to be thermally coupled to a circuit component, and includes a fluid supply section which directs a fluid flow along the axis toward an opposite side of the thermally conductive section. The thermally conductive section splits the fluid flow into a plurality of flow portions which each flow through the thermally conductive section in a direction approximately parallel to a plane perpendicular to the axis, the flow portions exiting the thermally conductive section at a plurality of respective locations disposed along a substantial portion of the periphery of the thermally conductive section.

Method and apparatus for cooling a circuit component

The present invention relates to heat exchangers, and more particularly to a heat exchange apparatus configured to operate in a free air stream. In an embodiment, a heat exchange apparatus configured to operate in a free air stream includes a heat exchange structure having a shape configured to conform to a body of a vehicle when in a stowed condition; and a deployment mechanism for moving the heat exchange structure to a deployed condition external to the vehicle. The heat exchange structure has a curved surface that is concave into the air stream when the heat exchange structure is in the deployed condition.

A method for cooling a structure includes flowing a saturated refrigerant through one or more passageways in the structure while maintaining the refrigerant at a substantially constant pressure. The method also includes evaporating at least a portion of the refrigerant at a substantially constant temperature throughout the passageways in the structure.

Method and system for cooling

A portable computer includes a housing containing a circuit component, and a temperature adjusting arrangement which has a thermally conductive section with a side facing approximately along an axis and thermally coupled to the component. A fluid supply section directs a fluid flow along the axis and the thermally conductive section splits the fluid flow into a plurality of flow portions which each flow through the thermally conductive section in a direction approximately parallel to a plane perpendicular to the axis, the flow portions exiting the thermally conductive section at a plurality of respective locations disposed along a substantial portion of the periphery of the thermally conductive section.

A cooling system ( ) includes a member ( A, B) with an opening ( ) therethrough, and includes first and second heat-conductive sections ( ) disposed adjacent the member on opposite sides thereof. A fluid supply section ( ) is disposed on a side of the first section opposite from the member, and directs a flow of fluid ( ) toward the first section. A portion ( ) of the fluid flows through the first section, and a different portion ( ) of the fluid flows through the other section.

Method and apparatus for removing heat from a plate

A cold plate for use in a thermal management system and a method of thermal management which comprises an inlet channel having coolant fluid disposed therein at a substantially uniform pressure throughout the inlet channel and an outlet channel having coolant fluid disposed therein at a substantially uniform pressure lower than the pressure in the inlet channel throughout the outlet channel. The cold plate includes a highly thermally-conductive metallic porous matrix filling the fluid passage, preferably of aluminum. The porous matrix is preferably from about two percent to about 15 percent percent solid.
