Abstract: An embedded heat pipe sandwich panel having components made using dissimilar materials is described. An exemplary embedded heat pipe sandwich panel comprises graphite faceskins secured to aluminum honeycomb core using traditional film adhesives. One or more aluminum heat pipes are embedded in the sandwich panel and thermally coupled to the faceskins using a high thermal conductivity gasket material disposed between the panel faceskins and the heat pipes.

Abstract: An improved thermal harness or thermal heat strap that comprises carbon based (graphite) fiber heat conducting elements coupled to graphite, composite, polymer, or metal end attachment brackets. An outer casing comprising a tubular braided sleeve surrounds the heat conducting elements and eliminates possible contamination caused by the graphite fibers. The thermal harness may be advantageously used in electronic applications to dissipate heat from high temperature components.

Abstract: Thermal interface materials for use in space applications. The thermal interface materials comprise a plurality of graphitized thermally conductive (carbon based) fibers 6 that are contained, immersed, or embedded, in one or more substantially non-outgassing polymer matrix materials. Both relatively stiff and relatively stiff and compliant polymer matrix materials may be used to secure the thermally conductive fibers. The thermally conductive fibers and non-outgassing polymer matrix material may be additionally cured to improve their conductive properties. The polymer matrix materials contain volatile condensable material of less than 0.1 percent and exhibit a total mass loss of less than 1.0 percent per an ASTM E595 procedure.

Abstract: 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.
