Apparatus and method for sintering metallic web heat pipe

Abstract

A method and an apparatus for sintering metallic web heat pipe. The pipe body of a heat pipe is held by a fastening unit. A metallic web is then inserted into the pipe body. A core rod is also inserted to the metallic web, such that the metallic web closely contacts the pipe body. The heat pipe is then sintered in an oven. Since the melting point of the metallic web is lower than that of the pipe body and the core rod, the metallic web is combined with the pipe body during the sintering process. The fastening unit then moves the heat pipe to a blocking unit. After the core rod penetrates a hole formed on the blocking unit, a holding unit is used to clamp the core rod, thereby pulling the core rod off from the heat pipe. In this manner, a heat pipe having a metallic web combined thereto is manufactured.

1 . A method for sintering metallic web heat pipe, comprising the steps of: 
 preparing a pipe body, which is securely hold by a fastening unit, and inserting a metallic web into the pipe body;    inserting a core rod into the metallic web, the core rod closely contacting the inner wall of the pipe body;    sintering the heat pipe in an oven, whereby the metallic web is melt to combine with the pipe body; and    moving the heat pipe to a blocking unit, and pulling off the core rod from the heat pipe through a hole on the blocking unit, thereby pulling the core rod away from the pipe body of the heat pipe.    
   
   
       2 . The method as recited in  claim 1 , wherein the metallic web comprises a bundle of multi-fiber.  
   
   
       3 . The method as recited in  claim 1 , wherein the metallic web comprises a multi-layered interwoven web.  
   
   
       4 . The method as recited in  claim 1 , wherein the fastening unit comprises a holding portion for holding the pipe body.  
   
   
       5 . The method as recited in  claim 1 , wherein the core rod is made of one of iron, iron alloy, nickel, nickel alloy, titanium and titanium alloy.  
   
   
       6 . The method as recited in  claim 1 , wherein the core rod comprises a slanted surface.  
   
   
       7 . The method as recited in  claim 1 , wherein the core rod is adhered with powder.  
   
   
       8 . The method as recited in  claim 7 , wherein the powder comprises carbon powder.  
   
   
       9 . The method as recited in  claim 1 , wherein the fastening unit comprises a power generation element and a clamp.  
   
   
       10 . The method as recited in  claim 9 , wherein the power generation unit is one of a combustion chamber, an oil pressure chamber and a motor.  
   
   
       11 . The method as recited in  claim 1 , wherein the melting point of the core rod is higher than that of the heat pipe and the metallic web.  
   
   
       12 . An apparatus for sintering a metallic web heat pipe, the apparatus comprising: 
 a fastening unit for holding the pipe body of a heat pipe;    a core rod inserted into the pipe body of the heat pipe for closely contacting a metallic web to the pipe body;    a blocking unit for blocking the heat pipe, allowing only the core rod to penetrate therethrough; and    a holding unit for holding one end of the core rod that penetrates through the blocking unit.    
   
   
       13 . The apparatus as recited in  claim 12 , wherein the fastening unit comprises a holding portion for holding the pipe body.  
   
   
       14 . The apparatus as recited in  claim 12 , wherein the metallic web comprises a bundle of multi-fiber or a multi-layered interwoven web.  
   
   
       15 . The apparatus as recited in  claim 12 , wherein the core rod is made of one of iron, iron alloy, nickel, nickel alloy, titanium and titanium alloy.  
   
   
       16 . The apparatus as recited in  claim 12 , wherein the core rod comprises a slanted surface.  
   
   
       17 . The apparatus as recited in  claim 12 , wherein the core rod is adhered with powder.  
   
   
       18 . The apparatus as recited in  claim 17 , wherein the powder comprises carbon powder.  
   
   
       19 . The apparatus as recited in  claim 12 , wherein the fastening unit comprises a power generation element and a clamp.  
   
   
       20 . The apparatus as recited in  claim 19 , wherein the power generation unit is one of a combustion chamber, an oil pressure chamber and a motor.  
   
   
       21 . The apparatus as recited in  claim 12 , wherein the melting point of the core rod is higher than that of the heat pipe and the metallic web.  
   
   
       22 . The apparatus as recited in  claim 12 , wherein the blocking unit includes a hole formed thereon.
