Heat pipe manufacturing method

Abstract

A heat pipe manufacturing method includes the steps of: providing a partially formed heat pipe with one open end; pouring a predetermined quantity of fluid working media into an intermediate pipe; solidifying the working media at a low temperature; inserting the solidified working media into the partially formed heat pipe; and vacuumizing and sealing the partially formed heat pipe.

1 . A heat pipe manufacturing method comprising:
 providing a partially formed heat pipe with an open end;   pouring a predetermined quantity of fluid working media into an intermediate pipe;   solidifying the working media at a low temperature;   inserting the solidified working media into the partially formed heat pipe at the low temperature; and   vacuumizing and sealing the partially formed heat pipe at the low temperature.   
     
     
         2 . The heat pipe manufacturing method of  claim 1 , further comprising the step of sealing the intermediate pipe after pouring the predetermined quantity of fluid working media into the intermediate pipe. 
     
     
         3 . The heat pipe manufacturing method of  claim 1 , wherein the partially formed heat pipe comprise a wall and a wick structure formed on the inner surface of the wall. 
     
     
         4 . The heat pipe manufacturing method of  claim 3 , wherein the wall is made by one of copper, aluminum, stainless steel, and alloy steel. 
     
     
         5 . The heat pipe manufacturing method of  claim 3 , wherein the wick structure is one of sintered type wick structure, screen mesh type wick structure, and grooved type wick structure. 
     
     
         6 . The heat pipe manufacturing method of  claim 3 , wherein an inner diameter of the intermediate pipe is smaller than an inner diameter of the heat pipe. 
     
     
         7 . The heat pipe manufacturing method of  claim 1 , wherein the intermediate pipe further comprises two openable covers attached on two ends of the intermediate pipe. 
     
     
         8 . The heat pipe manufacturing method of  claim 1 , wherein the working media is one of pure water, ammonia, and carbinol.
