Efficient heat sink is provided by soldering diodes to metal support bars which are brazed to a ceramic base. Electrical connections between diodes on adjacent bars are made flexible by metal strips which aid in heat dissipation.
Space molecular sink design to create vacuum environment, emphasizing pumping and test chamber instrumentation
Thermal path prevents voids and discontinuities which make heat sinks in electronic equipment inefficient. The thermal path combines the high thermal conductivity of copper with the resiliency of silicone rubber.
Rugged module package for thin film hybrid microcircuits incorporated a rigid, thermally conductive support structure, which serves as a heat sink, and a lead wire block in which T-shaped electrical connectors are potted. It protects the circuitry from shock and vibration loads, dissipates internal heat, and simplifies electrical connections between adjacent modules.
Gravity anomalies and convection currents, examining sphere and cylinder sinking beneath surface of viscous fluid
Stagnation point velocity and pressure distribution over heat-sink shielded reentry vehicle to test boundary layer heat transfer theories
Space molecular sink design to create vacuum environment, emphasizing pumping and test chamber instrumentation
Reparable modular system is used for packaging microelectronic flat packs and miniature discrete components. This three-dimensional compartmented structure incorporates etched phosphor bronze sheets and frames with etched wire conductors. It provides an effective heat sink for electric power dissipation in the absence of convective cooling means.
