Abstract

Invention discloses technology of production of various heat pipes in a single technological step which requires no vacuum equipment.

1 . A method of extrusion of closed profile wherein a compound or mix is disposed at the time of extrusion into inner volume of this extrusion in either liquid or gaseous or transient state.  
   
   
       2 . A method of  claim 1  wherein inner wall of said profile receives grooves due to said extrusion process.  
   
   
       3 . A method of  claim 2  wherein said grooves lines are twisted in uniform or zigzag or weave pattern around preferred direction of said extrusion.  
   
   
       4 . A method of  claim 1  wherein said profile is reshaped to different profile with nearly the same length, and said second profile has smaller area.  
   
   
       5 . A method of  claim 3  wherein said twist is uniform and the material strength of said extrusion and its wall thickness is sufficient to sustain lunch cycle of projectile utilizing either chemical combustion or compressed gases or electro magnetic propulsion.  
   
   
       6 . A method of  claim 1  where in addition to said compound a solid material in form of either continuous tape or string or similar, or in form of beads or pellets is disposed at the same time of extrusion.  
   
   
       7 . A method of  claim 4  wherein there is a plurality of location of said extrusion that are joint to plurality of other locations on the extrusion in a way that plurality of interconnected volumes is formed.  
   
   
       8 . A method of  claim 7  wherein some of said joints form interconnections of outer surface of said extrusion.  
   
   
       9 . A method of  claim 3  wherein said profile is reshaped to different profile with nearly the same length, and said second profile has smaller area, and groves of adjacent segments of inner surface are not parallel.  
   
   
       10 . A method of  claim 9  where in there is a plurality of location of said grooves that are joint to plurality of other locations on the extrusion in a way that plurality of interconnected channels is formed.  
   
   
       11 . A method of production of heat pipe devices wherein said complete and functional devices are created without use of vacuum or vacuum pumps.  
   
   
       12 . A heat pipe device wherein a capillary volume formed by plurality interconnected voids is formed by two essentially parallel and essentially smooth surfaces that are fused together in plurality of locations.  
   
   
       13 . A heat pipe device produced according to  claim 1  wherein said extrusion is segmented by plurality of seams into plurality of sealed discontinuous volumes.  
   
   
       14 . A heat pipe device of  claim 13  wherein material of said extrusion is metal.  
   
   
       15 . A heat pipe device of  claim 13  wherein material of said extrusion is glass.  
   
   
       16 . A heat pipe device of  claim 13  wherein material of said extrusion is ceramic.  
   
   
       17 . A heat pipe device of  claim 13  wherein material of said extrusion is polymer based.  
   
   
       18 . A heat pipe device of  claim 13  wherein material of said extrusion is fiber reinforced composite.  
   
   
       19 . A heat pipe device of  claim 13  wherein material of said extrusion is inorganic composite.  
   
   
       20 . A method of  claim 1  wherein said mix contains at least one element that accelerates chemical processes in material of said extrusion.
