METHOD OF REMOVING INEFFECTIVE PORTION OF FLAT HEAT PIPE

摘要

A method of removing ineffective portion of flat heat pipe is disclosed. The method includes the steps of providing a flat heat pipe; flattening out at least one wick-free flatten-out zone of the flat heat pipe and then sealing the flattened flatten-out zone by welding; and cutting off a cut-away section but reserving a remainder section of the flattened and sealed flatten-out zone, so that an ineffective portion is removed from the flat heat pipe. After being processed with the above method, the flat heat pipe can have effectively increased heat transfer efficiency and save a lot of space.

1. A method of removing ineffective portion of flat heat pipe, comprising the following steps:
providing a flat heat pipe; and the flat heat pipe internally defining a vacuum chamber, which is filled with a working fluid and has at least one wick structure formed on an inner wall surface thereof; flattening out at least one flatten-out zone that is located corresponding to a wick-free space in the chamber of the flat heat pipe, and then sealing the flattened flatten-out zone by welding, such that the flatten-out zone has a remainder section and a cut-away section; and cutting away the flattened and sealed cut-away section but reserving the remainder section, so that an ineffective portion of the flat heat pipe is removed.
