A low thermal resistance, low cost cooling or heating system and method of constructing the disclosed cooling system. The system may be formed by pressing a tube into a groove in a plate without the use of interface materials or epoxy. The disclosed system includes a plate having a channel adapted to receive a tube, such that the channel holds the tube in place after the tube is press fitted into the channel, thus forming an effective cooling or heating system without the need for addition of epoxy or interface material between the tube and the plate. One or more electronic components to be cooled or heated may be attached to both sides of the disclosed cooling system with equivalent cooling effectiveness. Operation of the disclosed system involves flowing an appropriate fluid through the tube that has been press fitted into the plate.

Tube-in-plate cooling or heating plate

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.
