HEAT PIPE AND METHOD OF PRODUCING THE SAME

摘要

A heat pipe ( 50 ) and a method ( 100 ) of producing the heat pipe are disclosed. The method includes the following steps: (1) inserting a mandrel ( 10 ) into a hollow metal casing ( 20 ) with a porous structure ( 30 ) combined to an outer surface of the mandrel; (2) filling powders ( 40 ) into a space formed between the hollow metal casing and the porous structure; (3) sintering the filled powders; (4) drawing the mandrel out of the hollow metal casing; and (5) sealing the hollow metal casing with a working fluid filled therein. The heat pipe produced by this method includes a composite wick structure ( 60 ) arranged in the hollow metal casing. By using this method, the mandrel can be easily drawn out of the hollow metal casing after the filled powders are sintered.
