Heat pipe

Abstract

A heat pipe has a hollow pipe body, a wick structure of screen mesh disposed on an internal wall of the pipe body and at least one support structure extended to press the wick structure of screen mesh tightly to the internal wall of the pipe wall. The support structure spiral in shape, and is formed by a continuous board. The support structure provides a support force to support the wick structure of screen mesh on the internal wall of the wick structure of screen mesh by a surface of the spiral board. The heat pipe provides capillary action.

1 . A structure used in heat pipes, comprising: 
 a hollow pipe body;    a wick structure of screen mesh assembled on an internal wall of the pipe body; and    at least one support structure spirally formed by a continuous board and inserted into the pipe body for outwardly extending to press the wick structure of screen mesh tightly to the inner wall of the pipe body, wherein the support structure provides a support force to support the wick structure of screen mesh on the internal wall of the pipe body by a surface of the spiral board.    
   
   
       2 . The heat pipe as claimed in  claim 1 , wherein the support body is a right spiral.  
   
   
       3 . The heat pipe as claimed in  claim 1 , wherein the support body is a left spiral.  
   
   
       4 . The heat pipe as claimed in  claim 1 , wherein the support body has a plurality of groove holes formed therein.
