Abstract
A method of making a heat pipe includes the steps of: providing a mandrel, a capillary wick and a straight tubular shell; inserting the mandrel and the capillary wick into the shell; cramming powder into the shell, wherein the powder can be sintered between the shell and the mandrel; sintering the shell having the mandrel, the capillary wick and the powder therein; and drawing the mandrel out of the shell and filling working media into the pipe, and vacuuming and sealing the pipe. The mandrel defines a longitudinal slot therein, and the capillary wick is positioned in the slot.

A method for forming a heat pipe, comprising:
- preparing a tubular shell;
- inserting a mandrel into the shell, wherein the mandrel defines a slot longitudinally extending in a circumferential periphery thereof, the slot being inserted with a capillary wick therein, the capillary wick having a portion protruding out of the slot;
- inserting powder into the shell to fill a space between the shell, the capillary wick and the mandrel;
- heating the powder so that the powder is sintered to the shell and the capillary wick;
- drawing the mandrel out of the shell;
- and
- injecting working fluid into the shell, vacuuming the shell and sealing the shell.
