METHOD FOR MANUFACTURING FLAT HEAT PIPE WITH SECTIONAL DIFFERENCES

摘要

A method for manufacturing a flat heat pipe with sectional differences includes following steps. First, form a plurality of grooves on an inner wall of a pipe body having one outer diameter. Subsequently, form a plurality of tubular sectional difference portions having various outer diameters on the pipe body. Then, degass an interior of the pipe body into vacuum and seal both ends thereof. Finally, press the respective sectional difference portions of the pipe body into flat.

1. A method for manufacturing a flat heat pipe with sectional differences, including steps of:
a) draw-forming a tubular hollow pipe body, the pipe body having one outer diameter, forming a plurality of grooves on an inner wall of the pipe body; b) making the pipe body to have a plurality of outer diameters along its length to thereby form a plurality of tubular sectional difference portions on the pipe body; c) degassing the interior of the pipe body into vacuum and sealing both ends of the pipe body; and (d) pressing the respective sectional difference portions of the pipe body into flat.
