    • A thermal harness comprising one or more tows of braided or bundled thermally conductive fiber extending from each of a plurality of heat generating devices to one or more heat dissipating devices. The harness may include an encapsulating membrane to contain the multiple tows. At each end or node of the tows, they are fanned out and splayed onto a patch of nonoutgassing polymer matrix material. A second piece of nonoutgassing polymer matrix material may be used to encapsulate the splayed tows at each node. The nonoutgassing polymer matrix material comprises high conductivity, small diameter fibers thermally coupled to the splayed tows of fiber and to the heat generating and heat dissipating devices. The node may be attached to the heat generating and dissipating devices using an adhesive or pyrolytic graphite flakes disposed between the polymer matrix material and the heat generating and dissipating devices. Alternatively, a plastic connector or a backing plate may secure the ends of the thermal harness to the heat generating and heat dissipating devices.
    • 一种热线束,其包括从多个发热装置中的每一个延伸到一个或多个散热装置的一个或多个编织或捆扎的导热纤维的丝束。 线束可以包括封装膜以容纳多个丝束。 在丝束的每个末端或节点处,它们被扇出并张开在不均匀的聚合物基质材料片上。 可以使用第二片非去气聚合物基质材料来封装每个节点处的被拉伸的丝束。 非除气聚合物基质材料包括热导率小的纤维,热纤维与发丝丝束和散热装置热连接。 节点可以使用设置在聚合物基体材料和发热和消散装置之间的粘合剂或热解石墨薄片附接到发热和耗散装置。 或者,塑料连接器或背板可以将热束的端部固定到发热和散热装置。
