Patent ID: 7117930

Claim:
A heat transfer device for dissipating heat from a heat source, said device comprising: a heat pipe including a vessel to be placed in thermally conductive relation to said heat source, said heat pipe comprising thermally conductive material at least at an elongated and flattened evaporator part and including a condenser part that is in fluid communication with said flattened evaporator part; a heat transfer medium for movement in a cycle between said evaporator part and said condenser part; a wicking material within said heat pipe that is capable of supporting a capillary flow of said heat transfer medium at least for part of said cycle; a base plate for at least partly supporting said heat pipe, said base plate having a surface to be directed toward said heat source, wherein said base plate has at least one channel extending across a full length of said surface of said base plate, wherein said channel is dimensioned to receive at least a portion of said elongated and flattened evaporator part of said heat pipe and said flattened evaporator part is disposed in said channel and extends substantially parallel to a plane of said base plate, so as to engage said heat source.
