Provided is a vapor-based heat transfer apparatus (e.g. a vapor chamber or a heat pipe), comprising: a hollow structure having a hollow chamber enclosed inside a sealed envelope or container made of a thermally conductive material, a wick structure in contact with one or a plurality of walls of the hollow structure, and a working liquid within the hollow structure and in contact with the wick structure, wherein the wick structure comprises a graphene material and the hollow structure walls comprise an evaporator wall having a first surface plane and a condenser wall having a second surface plane, wherein multiple sheets of the graphene material in the wick structure are aligned to be substantially parallel to one another and perpendicular to at least one of the first surface plane and the second surface plane. Also provided is a process for producing this apparatus.
A vapor-based heat transfer apparatus, comprising (a) a hollow structure comprising a thermally conductive material having a thermal conductivity no less than 5 W/mK, (b) a wick structure in contact with one or a plurality of walls of said hollow structure, and (c) a working liquid within said hollow structure and in contact with said wick structure, wherein said wick structure comprises a first graphene material and said a plurality of walls of said hollow structure comprise an evaporator wall having a first surface plane and a condenser wall having a second surface plane, wherein multiple sheets of said first graphene material in said wick structure are aligned to be substantially parallel to one another and perpendicular to at least one of said first surface plane and said second surface plane.
