A heat transfer device couples a heat generation member with a heat radiation member, and transfers heat from the heat generation member to the heat radiation member. The heat transfer device includes a composite member and a heat conductor. The composite member includes multiple carbon nanotubes and multiple carbon fibers which are mixed into a base material and complexed together, and the respective carbon fibers are crosslinked with each other by the carbon nanotubes. The heat conductor has one flexible end embedded in the composite member. The embedded one end is crosslinked with the carbon fibers in the composite member through the carbon nanotubes.

Inefficient dissipation of heat limits the performance of electronic devices. Thermal interface materials (TIMs) can be used in electronic devices to dissipate heat more effectively and efficiently. Nanocomposites have been prepared using functionalized boron nitride nanosheets (BNNS). The incorporation of soft-ligand functionalized BNNS in a metal matrix was used to nanofabricate kinetically-trapped nanocomposites TIMs.

A thermally superconducting radiator and a method for manufacturing the same. The thermally superconducting radiator comprises a plurality of separators and a plurality of thermally superconducting heat dissipation fins. The separators and the thermally superconducting heat dissipation fins are alternately arranged, and one end face of the separator is flush with one end face of the thermally superconducting heat dissipation fin, together forming a mounting surface suitable for mounting a power device. The thermally superconducting heat dissipation fins and the separators are fixedly connected. Replacing the conventional heat dissipation fins in the prior art with the thermally superconducting heat dissipation fins enables the thermally superconducting radiator to have a greater heat transfer rate and a more efficient fin efficiency. The fin efficiency of the heat dissipation fin is not affected by the height, which greatly improves the cooling capability of the radiator.
