Publication number: 20200221610Abstract: 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.Type: ApplicationFiled: March 23, 2020Publication date: July 9, 2020Inventors: Paul W.
