Coaxial capillary structure and ultra-thin heat pipe structure having the same

Abstract

A coaxial capillary structure and an ultra-thin heat pipe structure having the same are provided. The coaxial capillary structure is installed in an ultra-thin heat pipe and extended towards the length direction of a pipe body of the ultra-thin heat pipe, and includes: a primary transferring capillary part and a coaxially-arranged capillary part, wherein the primary transferring capillary part is composed of a plurality of fiber bundles for forming as an integral bundle, and the coaxially-arranged capillary part is formed through a plurality of weaving wires interwoven and reeled at the exterior of the primary transferring capillary part, thereby limiting each of the fiber bundles at the central portion of the coaxially-arranged capillary part for forming a compact structure. Accordingly, a better capillary transferring effect is provided.

         2 . The coaxial capillary structure according to  claim 1 , wherein each of the fiber bundles and each of the weaving wires are made of metal material or non-metal material of glass or carbon fibers. 
     
     
         3 . The coaxial capillary structure according to  claim 1 , wherein the material of which the fiber bundles are made is the same or different from the material of which the weaving wires are made. 
     
     
         4 . The coaxial capillary structure according to  claim 1 , wherein the outer diameter of the fiber bundles is smaller than the outer diameter of the weaving wires. 
     
     
         5 . An ultra-thin heat pipe structure having a coaxial capillary structure, including:
 an ultra-thin heat pipe, having a vapor flow channel formed inside a pipe body thereof; and   a coaxial capillary structure, installed in the pipe body of the ultra-thin heat pipe and extended towards the length direction thereof, and including:
 a primary transferring capillary part, composed of a plurality of fiber bundles for forming as an integral bundle; and 
   a coaxially-arranged capillary part, formed through a plurality of weaving wires interwoven and reeled at the exterior of the primary transferring capillary part, thereby limiting each of the fiber bundles at the central portion of the coaxially-arranged capillary part for forming a compact structure.   
     
     
         6 .
