Claim 0:
1. A two-phase micro-channel embedded closed loop pulsating heat pipe comprising:
a first sheet having a serpentine trace pattern comprising a trace pattern;
a second sheet bonded onto said first sheet, such that when said first sheet and said second sheet are bonded together to form a bonded plate, the bonded plate defining a contiguous serpentine micro-channel in said bonded plate, said channel comprising a generally rectangular cross-sectional shape, a bottom wall, a top wall opposing said bottom wall, and two opposing side walls;
wherein said serpentine micro-channel defines a closed loop adapted to contain fluid within said serpentine micro-channel; and
a working fluid partially filling said channel in liquid and or vapor form;
wherein said micro-channel comprises one or more obstacles, at least one of said obstacles selected from the group essentially consisting of:
a hemicylindrical obstruction spanning two opposing walls of said bottom wall, a top wall, and two opposing side walls,
a semispherical obstacle set on at least one of said top wall and said bottom wall, and/or
a hemicylindrical obstacle set on at least one of said top wall and said bottom wall, said hemicylindrical obstacle spanning between said side walls;
said one or more obstacles mounted on at least one of said top wall, bottom wall, and/or side walls;
wherein said plate comprises a first region defining a condenser region coupled to a heat sink and a second region comprising an evaporator region coupled or near at least one heat source.
