Heat pipe

Abstract

A heat pipe ( 10 ) includes a pipe body ( 30 ) filled with working fluid, a screen mesh ( 50 ) located in the pipe body, a porous support member ( 70 ) supporting the screen mesh to contact with an inner wall ( 32 ) of the pipe body.

1 . A heat pipe comprising: 
 a hollow pipe body having an inner wall;    a mesh structure located in the pipe body, and    a porous support member supporting the mesh structure to contact with the inner wall of the pipe body.    
   
   
       2 . The cooling device as claimed in  claim 1 , wherein the support member is disposed in a central portion of the pipe body, the mesh structure is sandwiched between the pipe body and the support member.  
   
   
       3 . The cooling device as claimed in  claim 1 , wherein the support member is column shaped and extends along an axial direction of the pipe body.  
   
   
       4 . The cooling device as claimed in  claim 3 , wherein support member extends continuously along the axial direction of the pipe body.  
   
   
       5 . The cooling device as claimed in  claim 4 , wherein support member extends discretely along the axial direction of the pipe body, and comprises several sections and a space is defined between two neighboring sections.  
   
   
       6 . The cooling device as claimed in  claim 1 , wherein the support member is hollow and defined a through hole in a central portion thereof.  
   
   
       7 . The cooling device as claimed in  claim 1 , wherein the support member is solid.  
   
   
       8 . The cooling device as claimed in  claim 1 , wherein the support member is made of one of metal foam and porous polymer material.  
   
   
       9 . The cooling device as claimed in  claim 8 , wherein the metal foam is selected from following material: copper, aluminum, magnesium, nickel.  
   
   
       10 . The cooling device as claimed in  claim 8 , wherein the porous polymer material is polyethylene.  
   
   
       11 . The cooling device as claimed in  claim 1 , wherein a volume ratio of pores of the support member is larger than 50%.  
   
   
       12 . A heat pipe comprising: 
 a hollow pipe body having an inner wall;    a mesh structure disposed on the inner wall of the pipe body, and    a column shaped support member disposed in a central portion of the pipe body to support the mesh structure to contact with the inner wall of the pipe body, the support member having pores therein for passage of vapor.    
   
   
       13 . The cooling device as claimed in  claim 12 , wherein support member is made of one of metal foam and porous polymer material.  
   
   
       14 . The cooling device as claimed in  claim 13 , wherein a volume ratio of pores of the support member is larger than 50%.  
   
   
       15 . The cooling device as claimed in  claim 14 , wherein the support member is hollow and defined a through hole therein.  
   
   
       16 . The cooling device as claimed in  claim 14 , wherein the support member extends discretely along an axial direction of the pipe body, and comprises several sections and a space is defined between two neighboring sections.  
   
   
       17 . A heat pipe comprising: 
 a hollow pipe body having an inner wall;    a mesh structure received in the hollow pipe body; and    a support member made of metal foam received in the hollow pipe body and pressing the mesh structure against the inner wall of the pipe body.    
   
   
       18 . The heat pipe of  claim 17 , wherein the support member is continuously extended in the pipe body.  
   
   
       19 . The heat pipe of  claim 17 , wherein the support member is discrete in the pipe body.  
   
   
       20 . The heat pipe of  claim 17 , wherein the support member is hollow.
