Abstract:
A method for providing pre-placed, pre-brazed feed throughs in the substrate (4) of a hermetic package corresponding to the terminal leads (6b) of the encased circuit COTS components (6). The substrate (4) may include directly bonded copper (DBC) regions forming circular shapes (10) where the holes for the special connectors of the present invention will be located. These holes will correspond to the leads of the circuit component (6) that will be mounted to it. Holes are laser or mechanically drilled into the substrate (4) inside the circular shapes (10) formed in the DBC. To form the feed through, a bushing (12), such as a blind copper rivet, is brazed in the hole, with the open end thereof oriented toward the component-side of the substrate. These open ends can accept the leads of the circuit component (6), like the holes of a conventional PC circuit board.
Abstract:
Heat exchange devices (1) and methods of using and making them are disclosed. The heat exchange devices (1) have an elongate core (2) with a helical member (3) coiling along the outer surface of the core and extending along the longitudinal axis of the core. The heat exchange devices can be used alone or in groups, wherein a plurality of heat exchange devices can be connected independently to a substrate (10) and be disconnected from adjacent heat exchange devices. Fluids can be forced between the heat exchange devices to facilitate heat transfer.
Abstract:
The heat exchange system for conducting heat away heat-producing electronic components (22) comprising a metal tube (10) defining a flow channel for a cooling fluid, wherein the tube (10) has an inner surface (17) that comprise s a plurality of integral fins (12), and an outer surface (11, 13, 15) that is in direct contact with the heat producing components (22). The invention further provides a self-cooling, self-supporting electronic assembly that comprises one or more high-power electronic devices (22), the heat exchange system (10) and an attaching system (23, 25, 46) for attaching high-power electronic devices (22) to the heat exchange system (10). The invention further provides a method of cooling a heat producing means.
Abstract:
The present invention provides a heat exchange system for conducting heat away from high-power, heat-producing electronic components by conduction and convection. The heat exchange system comprises a metal tube that has been forged and drawn so as to define a flow channel for a cooling fluid, wherein the tube has an inner surface that comprises a plurality of integral fins that are structured and arranged to increase the available surface area of the inner surface of the metal tube exposed to the fluid and an outer surface that is in direct communication with the heat producing components. Coolant fluids are circulated through the flow channel, preferably, at turbulent flow conditions to minimize thermal resistance. The invention further provides a self-cooling, self-supporting electronic assembly that comprising one or more high-power electronic devices, the heat exchange systems, and an attaching system for attaching high-power electronic devices to the heat exchange system. The invention further provides a method of cooling a heat producing means comprising the steps of: providing a heat exchange system that is in direct communication with the heat-producing electronic components and circulating a fluid through the heat exchange system to conduct heat away from said heat exchange system and the heat producing electronic components.
