A wedge lock for use with a single board computer includes a cooling plate positioned with respect to a printed circuit board (PCB), a clamp device configured to secure the single board computer in an operating environment, and a heat conductance plate positioned along a top surface of the cooling plate and a top surface of the clamp device to facilitate conduction cooling of the PCB.
Abstract:
A locking retainer for retaining an electronic module or printed circuit card in slots of a chassis. The retainer includes at least three wedge members movably linked to each other and disposed in longitudinal sequence along a longitudinal axis. The retainer can be made relatively smaller in height by moving the wedge members longitudinally such that a longitudinal distance between a first wedge member and a last wedge member of the sequence becomes smaller without the wedge members being longitudinally displaced along a common internal longitudinal element. All portions of the locking retainer that the middle wedge member is longitudinally moveable relative to do not extend through a theoretical plane disposed at a longitudinal midpoint of the middle wedge member and oriented normal to the longitudinal axis. The elimination of a central rail permits the wedge segments to have much greater contact area for greater thermal energy flow.

A conduction-cooled enclosure comprises a card guide having a card guide channel, at least one controlled-volume cavity in the card guide channel, and a thermal interface material (TIM) in the at least one controlled-volume cavity.
Abstract:
An avionics chassis comprises a composite housing, a radio wave shield, and a lightning strike conductive e path, wherein the radio wave e shield attenuates electronic interference entering and leaving, the housing, and the lightning strike conductive path directs the current from a lightning strike away from an inventor of the housing.
Abstract:
An apparatus for cooling an enclosure provided. The enclosure has at least one opening for receiving cool air and discharging heated air. The apparatus includes a vortex tube with a first end for discharging warm air and a second end for discharging cool air. The apparatus further includes an inlet between the ends of the vortex tube for directing compressed air tangentially into the interior of the vortex tube. A first housing covers the first end of the vortex tube and creates a space through which warm air is channelled to the exterior. The vortex tube is connected by an attachment to the opening of the enclosure so that the vortex tube can discharge cool air into the interior of the enclosure. The apparatus further includes an air outlet conduit at an end of the attachment to facilitate discharge of heated air for the enclosure. Also, the apparatus includes at least one barrier that permits the outflow of warm air from the first housing and heated air from the air outlet conduit while blocking the inflow of moisture and other substances.
Abstract:
The invention centers around a circuit board assembly (12) having a heat sink (30) with a buss bar (20) integrally formed therein. Preferably, the heat sink (30) is provided between two parallel, opposed circuit boards (14, 16). The buss bar (20) is provided between the two circuit boards and is in electrical contact with circuit modules (18) provided on both of the circuit boards (14, 16). The heat sink (30) effectively conveys heat away from the circuit board assembly (12) generated by current flowing through the several circuit modules (18) provided on the circuit boards (14, 16). Preferably, the buss bar (20) is electrically insulated from both the circuit boards (14, 16) and the heat sink (30) but electrically connected to the circuit modules (18) provided on the surfaces of the circuit boards (14, 16) by terminals (56, 58) protruding from the opposed surfaces of the buss bar (20).
