Abstract

A method for fabricating a metal micro heat pipe with a polygonal cross-section including at least two concave sides to allow working fluid to flow by capillary force generated at the edges of the micro heat pipe. The concave sides are each formed of a single metal layer via a single drawing process. The polygonal cross-section is triangular, and the micro heat pipe is formed of a single metal plate.

Claims

exact text as granted — not AI-modified

1 . A method comprising: 
 fabricating a metal micro heat pipe with a polygonal cross-section including at least two concave sides to allow working fluid to flow by capillary force generated at the edges of the micro heat pipe, the at least two concave sides each formed of a single metal layer via a single drawing process, wherein the polygonal cross-section is triangular, and the micro heat pipe is formed of a single metal plate.    
   
   
       2 . The method of claim  16 , wherein a plurality of micro heat pipes with a polygonal cross-section are combined together in parallel, and working fluid is allowed to flow by capillary force generated at the edges of each of the micro heat pipes.  
   
   
       3 . The method of claim  16 , wherein the edges of the metal micro heat pipe act as a wick.
