Abstract
A heat pipe manufacturing method includes the steps of preparing a pipe and a wick structure; placing the wick structure in the pipe, vacuuming the pipe, and filling a working fluid in the pipe; and sealing the pipe. By manufacturing a heat pipe with this method, the risk of damaging the wick structure in the pipe during bending or pressing the pipe can be avoided to thereby ensure increased good yield. Further, with this method, the pipe can be pressed to form a thin heat pipe to thereby provide increased flexibility in production.
Claims7
A method of manufacturing a heat pipe, comprising the following sequence:
- preparing a pipe;
- pre-assembling a wick structure;
- placing the pre-assembled wick structure in the pipe,
- vacuuming the pipe,
- filling a working fluid in the pipe;
- and
- performing diffusion bonding heat treatment on the pipe to achieve increased binding of the wick structure to the pipe;
- and
- sealing the pipe.
