Heat pipe structure

Abstract

A heat pipe structure, having a tubular member, a support member and a wick structure. The tubular member is hollow to accommodate the support member and the wick structure therein. The wick structure is located between the tubular member and the support member. The wick structure is supported by the support member to be attached to an interior wall of the tubular member. The material melting point of the wick structure is lower than those of the tubular member and the support member. Therefore, the support member maintains good supporting function during sintering process, such that the wick structure can be adequately attached to interior wall of the tubular member.

1 . A heat pipe structure, comprising: 
 a hollow tubular member;    a support member disposed in the hollow tubular member; and    a wick structure supported by the support member and attached to an interior wall of the tubular member; wherein    the wick structure is fabricated from a material with a melting points lower than those of materials for fabricating the tubular member and the support member.    
   
   
       2 . The structure of  claim 1 , wherein the support member includes an elongate spiral structure extending through the hollow tubular member.  
   
   
       3 . The structure of  claim 1 , wherein the support member includes an elongate wire spiral structure extending through the hollow tubular member.  
   
   
       4 . The structure of  claim 1 , wherein the support member includes a winding coil extending within the tubular member.  
   
   
       5 . The structure of  claim 1 , wherein the support member is perforated with a plurality of holes.  
   
   
       6 . The structure of  claim 1 , wherein the material for fabricating the support member has the melting point lower than that of the material for fabricating the tubular member.  
   
   
       7 . The structure of  claim 1 , wherein the wick structure is in the form of a screen mesh.  
   
   
       8 . The structure of  claim 1 , wherein the wick structure is in the form of a fiber bundle.
