Abstract
In a lightweight heat pipe and a method for making the lightweight heat pipe, a first hollow pipe and a second hollow pipe making of two different materials are provided. The first hollow pipe is disposed into the second hollow pipe along an axial direction of the second hollow pipe. An inner wall surface of the second hollow pipe is attached on an outer wall surface of the first hollow pipe to combine the first and the second hollow pipes as a pipe body of the heat pipe. An inner space of the first hollow pipe is then vacuumed, and the pipe body is sealed after the working fluid is filled in the inner space of the first hollow pipe to finish the heat pipe.
