| 1. A method for manufacturing a heat transfer device, comprising:
mortising a porous core into a first hollow tube;
providing a second hollow tube having a closed end, said closed end having a second surface;
hole-punching to form a second hole at said second surface;
hole-widening at an opposite end of said second hollow tube at the same time of performing said step of hole-punching to form
said second hole;
mortising said second hollow tube on said first hollow tube;
covering a heat conductor on said first hollow tube; and
connecting a connecting pipe to said first hollow tube and said second hollow tube.
