Abstract
A heat sink is provided having a bundle of thermally conductive fibers that extend from a heat receiving end to a heat dissipating end where they are splayed as extremely numerous fins of one or plural coalesced fibers to enlarge the effective heat convecting area. The splayed fins are supported or maintained in a splayed array by a structure. Heat dissipation capability is augmented by forcing a cooling fluid such as air through the splayed fins. The fins are initially caused to separate or splay by various techniques including electrostatic spreading, layering, tape rolling, selective coating removal, and elastic rebound, and are maintained in the splayed position by a frame, adhesion, or elastomers.
