Wick structure of heat pipe

Abstract

A wick structure is attached on an internal sidewall of a heat pipe. The wick structure is a one-layer woven wick. At least one weaving direction of the meshes of the woven wick contains a plurality of fiber bundles each including two more woven fibers to weave to a plurality of single fiber. As such, the fiber bundles of the one-layer woven wick provide enhanced capillary force like a multi-layer wick structure.

1 . A heat pipe comprising a tubular member and a wick structure attached to an interior surface of the tubular member, 
 wherein the wick structure is a woven wick with meshes formed by a plurality of fibers, at least one weaving direction of the meshes contains a plurality of fiber bundles including two more weaving fibers each to weave to a single fiber.    
   
   
       2 . The heat pipe of  claim 1 , wherein the meshes of the fibers are orthogonal.  
   
   
       3 . The heat pipe of  claim 1 , wherein the fibers are made of copper.  
   
   
       4 . The heat pipe of  claim 1 , wherein the weaving fibers includes a plurality of transversal fibers and a plurality of longitudinal fibers.  
   
   
       5 . The heat pipe of  claim 4 , wherein the longitudinal fibers are formed in a plurality of fiber bundles.  
   
   
       6 . The heat pipe of  claim 4 , wherein the transversal fiber and the longitudinal fiber are in different size.  
   
   
       7 . The heat pipe of  claim 1 , wherein all the weaving fibers are formed in a plurality of fiber bundles.  
   
   
       8 . The heat pipe of  claim 1 , wherein the weaving fibers include at least two kinds of sizes.  
   
   
       9 . The heat pipe of  claim 1 , further comprising a support member pressing the wick structure firmly attached to the tubular member.  
   
   
       10 . The heat pipe of  claim 9 , wherein the support member has a mesh structure.  
   
   
       11 . The heat pipe of  claim 9 , wherein the support member has a spiral structure.  
   
   
       12 . The heat pipe of  claim 9 , wherein the support member has a plurality of holes formed thereon.
