Multi-layer wick structure of heat pipe

Abstract

A multi-layer wick structure attached to a tubular member of a heat pipe includes a first weaving mesh of wick layer attached to an interior surface of the tubular member, and a second weaving mesh of wick layer encircled by the first wick layer so that the first wick layer is sandwich between the tubular member and the second wick layer. The first and the second weaving meshes of the wick layer include a plurality of first and second weaving wires, respectively, and the first weaving wire has the diameter smaller than that of the second weaving wire.

1 . A multi-layer wick structure attached to a tubular member of a heat pipe, comprising: 
 a first wick layer having a plurality of first weaving meshes attached to an interior surface of the tubular member; and    a second wick layer having at least a second weaving mesh, which is encircled by the first wick layer so that the first wick layer is sandwiched between the tubular member and the second wick layer, wherein the first weaving mesh comprises a plurality of first weaving wires and the second weaving mesh comprises a plurality of second weaving wires, and the first weaving wire has the diameter smaller than that of the second weaving wire.    
   
   
       2 . (canceled)  
   
   
       3 . The structure of  claim 1 , wherein the second wick layer has a plurality of weaving meshes.
