    • An electronics module designed to efficiently remove heat from enclosed circuit boards via one or more configurable heat conduits. Each heat conduit is custom-configured to provide good thermal contact between the corresponding heat-generating electronic device of an enclosed circuit board and the clamshell housing that encloses the circuit board. Good thermal contact between the clamshell housing and the outer case of the electronic module facilitates efficient heat transfer to the finned exterior surface of the outer case, where the heat is dissipated into the ambient environment via thermal conduction, natural convection, forced convection, and/or thermal radiation. Depending on the topology of the circuit board and the individual characteristics of the electronic device to be cooled, the corresponding configurable heat conduit might be based on a nested heat-sink coupler, a fitted movable plug, or a flexible ribbon-shaped heat pipe.
    • 电子模块设计用于通过一个或多个可配置的热导管有效地从封闭的电路板去除热量。 每个热导管被定制构造成在封闭的电路板的相应的发热电子器件与包围电路板的蛤壳式壳体之间提供良好的热接触。 蛤壳式壳体与电子模块的外壳之间的良好的热接触有助于有效地传热到外壳的翅片外表面,其中热量通过热传导,自然对流,强制对流和/ 或热辐射。 根据电路板的拓扑结构和要冷却的电子设备的各个特性,相应的可配置热导管可以基于嵌套的散热器耦合器,配合的可移动插头或柔性带状热管。
