Heat pipe and method for manufacturing the same

A method for manufacturing a heat pipe, the method comprising:

• providing a tube with a wick structure on an inner surface thereof, the tube defining a chamber therein, and further defining an evaporating section and a condensing section;
• insolating the evaporating section from the condensing section by blocking the chamber, the wick structure extending from the evaporating section to the condensing section along the inner surface of the tube to form a working medium channel;
• evacuating the evaporating section and the condensing section, injecting a working medium into the tube, and sealing the tube;
• defining at least one through hole in each of the evaporating section and the condensing section of the tube;
• and
• arranging at least one metal pipe to communicate the at least one through hole of the evaporating section with the at least one through hole of the condensing section, thereby defining at least one vapor channel.

A heat pipe comprising

• a hollow tube, two ends of the tube being sealed and the tube defining a chamber therein;
• a wick structure provided on an inner surface of the tube;
• and
• a working medium provided in the chamber;
• wherein the tube comprises an evaporating section and a condensing section, the evaporating section is isolated from the condensing section, the wick structure extends from the evaporating section to the condensing section along the inner surface of the tube to form a working medium channel, two through holes are defined in each of the evaporating section and the condensing section of the tube, and two metal pipes communicate the two through holes of the evaporating section with the two through holes of the condensing section, respectively, to form two vapor channels.
