<p>In the heat pipe, wicks for refluxing the condensed and liquefied operation fluid into the heating portion are composed chiefly of a carbon fiber. The carbon fiber is not specially bundled, but is simply pressed and fastened onto the inner peripheral surface of a closed metal pipe by a pressing fitting, or is formed in a sandwich construction using a metal gauze. Or, the carbon fiber is knitted with wefts in the form of a cloth. Relying upon any structure, the capillary tube pressure can be increased, pressure loss of the liquid-phase operation fluid can be reduced, and the heat transfer ability can be increased. Furthermore, the heat pipe exhibits flexibility.</p> |
