| 1. A heat transfer device for transferring a heating source from a heating device, said heat transfer device comprising:
an evaporator, said evaporator comprising:
a first hollow tube having a first open end and a first closed end opposite to said first open end;
a porous core mortised inside said first hollow tube and having a first end and a second end opposite to said first end, wherein
the porous core has a fluid channel surrounded by and located inside the porous core and extending along a direction from
said first end to said second end, and said fluid channel is open at said first end and is close at said second end;
a second hollow tube having a second open end and a second closed end opposite to said second open end, wherein a part of
said first hollow tube is mortised and secured inside said second hollow tube, the other part of said first hollow tube is
exposed outside said second hollow tube, said first open end is mortised and secured inside said second open end, a direction
from said first closed end to said first open end is opposite to another direction from said second closed end to said second
open end, said porous core is located between said first closed end and said second closed end said second hollow tube has
a fluid reservoir therein, and said fluid reservoir is located within said second hollow tube and beside said first end of
said porous core and communicates with said fluid channel through an opening at said first end;
a connecting pipe connected to said evaporator, said connecting pipe being used for containing a working fluid; and
a condenser on said connecting pipe.
