Abstract
Official abstract text for this publication.
A heat pipe having enhanced heat transport capacity that can be manufactured easily is provided. The heat pipe 1 comprises a sealed container 2 and a wick structure 10 . The wick structure includes a first wick 11 formed of copper fibers 11 a , and a second wick formed of carbon fibers 12 a . The first wick 11 is sintered to be fixed to an inner face 21 a of a flat wall 21 while holding the second wick 12 therein.
First claim
Opening claim text (preview).
What is claimed is: 1 . A heat pipe, comprising: a sealed container flattened to have a pair of flat walls and sealed at both longitudinal ends; a working fluid encapsulated in the container; a wick structure that pulls the working fluid by a capillary pumping; an evaporating portion that is situated on one of the longitudinal ends of the container at which evaporation of the working fluid takes place; and a condensing portion that is situated on the other longitudinal end of the container at which condensation of the working fluid takes place; wherein the wick structure includes a first wick formed of a plurality of copper fibers extending from the condensing portion to the evaporating portion, and a second wick formed of a plurality of carbon fibers; wherein the second wick is heaped on an inner face of one of the flat walls of the container; and wherein the first wick is fixed to the inner surface of said one of the flat walls of the container while covering the heap of the second wick. 2 . The heat pipe as claimed in claim 1 , wherein the second wick is formed from the condensing portion to the evaporating portion. 3 . The heat pipe as claimed in claim 1 , wherein the second wick is formed only in the evaporating portion. 4 . The heat pipe as claimed in claim 1 , wherein a diameter of each carbon fiber is smaller than that of each copper fiber.
