摘要： An assembled circuit board has a topology that defines positions, dimensions and power dissipation of components mounted to the circuit board, including a high power component and one or more low power components. A cold plate makes thermal contact to the high power component through a thermal interface material. A thermally conductive sheet overlays the circuit board and is formed to match the topology of the low power component or components. The sheet has a first portion that makes thermal contact with the cold plate and a second portion that overlays the low power component or components. The cold plate removes heat directly from the high power component and indirectly through the thermally conductive sheet from the low power component or components. The thermally conductive sheet conforms to the topology of the low power components either by preforming or by flexibility.

摘要： A cold plate structure, wherein a thermally active region includes fins metal injection molded in a single piece with a fin base sufficiently thin so that the active region mechanically conforms to the heat generating device that the cold plate cools. The fin base is formed as a common structure with a bottom wall of the cold plate, reducing thermal resistance between the device and the fins and also enhancing mechanical flexibility. Another cold plate structure can include multiple thermally active regions, with flexible outer walls and a reduced thickness between active regions, allowing for position variation between multiple heat generation devices that are cooled by the common cold plate. A common base having multiple physically separate active regions can be metal injection molded in a single step, or bases of multiple active regions can be formed individually and joined later to form a common single cold plate structure.

摘要： An apparatus for cooling an electronic component has a planar top member of a thermal energy conductive material and a parallel planar bottom member of the material, the planar bottom member including a surface having regions configured for heat exchange contact with the electronic component. The planar top member has a plurality of stamped indent formations at a plurality of locations, each indent formation providing a contact surface such that the planar top member is affixed to the bottom member by braze or solder at each contact surface. Alternatively, the planar bottom member also has a plurality of stamped indent formations in alignment with indent formations of the top member. The planar top member is affixed to the bottom member by brazing or soldering each respective contact surface of an indent formation of the planar top member to an opposing contact surface of a corresponding indent formation of the parallel planar bottom member.

摘要： An apparatus includes a first circuit board including first components including a load, and a second circuit board including second components including switching power devices and an output inductor. Ground and output voltage contacts between the circuit boards are made through soldered or connectorized interfaces. Certain components on the first circuit board and certain components, including the output inductor, on the second circuit board act as a DC-DC voltage converter for the load. An output capacitance for the conversion is on the first circuit board with no board-to-board interface between the output capacitance and the load. The inductance of the board-to-board interface functions as part of the output inductor's inductance and not as a parasitic inductance. Sense components for sensing current through the output inductor are located on the first circuit board. Parasitic inductance of the board-to-board interface has less effect on a sense signal provided to a controller.

摘要： An optical coupling system includes a substrate, an electronic die comprising a plurality of coupling holes for passing light, an optical element die attached to a bottom surface of the electronic die, the electronic die attached to the substrate such that the electronic die covers a cavity in the substrate and the optical element die resides within the cavity of the substrate. The system may also include a thermally conductive lid that covers and contacts the electronic die and the substrate and has a coupling aperture that enables light that passes through the coupling holes to pass through the thermally conductive lid. The system may also include an optical cable coupler comprising a coupling section that laterally fits within the coupling aperture and a body section disposed above the coupling section that is laterally larger than the coupling section. A method for providing the above system is also disclosed herein.

摘要： An apparatus for cooling an electronic component has a planar top member of a thermal energy conductive material and a parallel planar bottom member of the material, the planar bottom member including a surface having regions configured for heat exchange contact with the electronic component. The joined planar top and bottom members have a sidewall structure of reduced height (and generally the height of the cold plate) between active areas in order to improve flexibility. The stiffness of the sidewalls is reduced by very advantageously reduce the height of the sidewalls. In one embodiment, the sidewalls are shorter in height corresponding to regions only between active areas. Alternatively, the sidewalls are of reduced height everywhere by insetting the active areas within the top and/or bottom sheets.

摘要： An inductor includes a conductor having a first end and a second end, wherein the first end, the second end, or both ends are configured to be mounted on a substrate and configured to receive a heat flow; and one or more magnetic cores surrounding a first portion of the conductor, the first portion of the conductor being intermediate the first end and the second end of the conductor. A second portion of the conductor not surrounded by the one or more magnetic cores is configured to transfer the heat flow from the conductor.
