Supportive wick structure of planar heat pipe

Abstract

A supportive wick structure of a planar heat pipe is provided having two panels and a supportive body with a plurality of low guides and through holes. The supportive body provides flow channels for a working fluid of the heat pipe in two directions. The flow guides formed by flow guide projections enhance structural strength and provide channels for the working fluid.

What is being claimed is:  
     
         1 . A supportive wick structure of a planar heat pipe, comprising at least a supportive body being a thin plate formed with a plurality of flow guide projections thereon, said flow guide projections each defining a pierced hole by pressing; said flow guide projections and said flat plate being correspondingly supported to an upper panel and a lower panel of the planar heat pipe, so that the supportive body is disposed between the upper panel and the lower panel to form a two dimensional flow space; whereby a working fluid is able to flow omni-directionally within the planar heat pipe.  
     
     
         2 . The supportive wick structure of a planar heat pipe as in  claim 1 , wherein said flat palate of said supportive body is formed with a plurality of flow guide slots.  
     
     
         3 . The supportive wick structure of planar heat pipe as in  claim 2 , wherein said flow guide slots are correspondingly positioned beside said flow guide projections.  
     
     
         4 . The supportive wick structure of a planar heat pipe as in  claim 1 , wherein said flow guide projections of said supportive body are arranged in a matrix form.  
     
     
         5 . The supportive wick structure of a planar heat pipe as in  claim 1 , wherein said supportive body has an upper end and a lower end each disposed with a wick layer.  
     
     
         6 . The supportive wick structure of a planar heat pipe as in  claim 1 , wherein said guide projections each have a trapezoidal shape or a semicircular shape for compression.  
     
     
         7 . The supportive wick structure of planar heat pipe as in  claim 1 , wherein said guide projections are irregular or differ in size, respectively.  
     
     
         8 . The supportive wick structure of a planar heat pipe as in  claim 1 , wherein said supportive body is made of wick material.
