Abstract: A circuit board module for a supercomputer includes quick connections for power, ground, coolant quick connects, and circuit quick connects. The quick connections provide for insertion of modules with substantial savings in time and effort. The electrical power and ground connections and the liquid coolant connections engage and disengage automatically upon insertion and removal of the modules. The circuit quick connects require only insertion of a camming tool for connection and disconnection. The modules require no bolting or unbolting of clamps or hoses for the various connections.

Abstract: The present invention provides a microchannel heat sink with a thermal range from cryogenic temperatures to several hundred degrees centigrade. The heat sink can be used with a variety of fluids, such as cryogenic or corrosive fluids, and can be operated at a high pressure. The heat sink comprises a microchannel layer preferably formed of silicon, and a manifold layer preferably formed of glass. The manifold layer comprises an inlet groove and outlet groove which define an inlet manifold and an outlet manifold. The inlet manifold delivers coolant to the inlet section of the microchannels, and the outlet manifold receives coolant from the outlet section of the microchannels. In one embodiment, the manifold layer comprises an inlet hole extending through the manifold layer to the inlet manifold, and an outlet hole extending through the manifold layer to the outlet manifold. Coolant is supplied to the heat sink through a conduit assembly connected to the heat sink.

Abstract: An electrical connector (39) provides high density interconnections through contact paths of printed circuit pads (12, 31) via flexible circuit (22) having contact pads (26, 28) driven by a canted coil spring (40) formed of a shape memory alloy selectively responsive to variations in temperature applied to the coil through a medium, heated or cooled and supplied via passage (62) in the connector.

Abstract: The invention relates to a rotatable high-current connector 1A, 1B for establishing an electric power supply to movable consumers in closed chambers. The high-current connector includes several rotatable, coaxial pipes 2, 3, 55, 46 for the conduit of a current and a cooling agent. The pipes concerned 2, 3, 55, 46 are at one end provided with flanges 9, 13, 14, 11. Two stationary counter flanges 19, 20 which are insulated with respect to one another are disposed coaxially to these two flanges 9, 13. The electric connection is established via two bundles of strands 17, 18.

Abstract: The invention is directed to an electric plug connector having a cooled connector component on a consumer where an intense heat is generated. The plug connector includes a movable connector component having a flexible supply line and both connector components are configured with heat-contact surfaces which define a low heat resistance when in contact with each other. In the movable connector component, at least one electrical line part is connected to a part made of a good insulating and heat-conductive material. The flow of heat to the heat-contact surface of the movable connector component takes place through this part made of insulating and good heat-conductive material.

Abstract: A connector assembly for transferring high-frequency current into or from a Litz-wire electrical cable having multiple conductor strands includes a transition connector component, a terminal connector component, and a coupling collar. The transition component has an annular groove which receives the splayed ends of the multiple conductor strands and makes electrical connection therewith by soldering of the conductor strand ends to the transition component at the groove. The transition component also has a central opening through it for providing flow communication with the internal coolant flow channel of the electrical cable. The terminal connector component has an orifice through it for establishing flow communication between the transition component opening and an external source of coolant. The terminal component also has a tab projecting from it for making an external electrical connection. The transition and terminal components are electrically connected together by fasteners.
