Sweating-boosted air cooled heat-pipe condensers employing a nanowick micro fin structure to form a sweating boosted heat dissipation system, wherein the nanowicks may be layered.

On-demand sweating-boosted air cooled heat-pipe condensers

The present disclosure relates to efficient condensing operations and apparatuses. Methods of fabricating condensers and specifically condenser surfaces are also disclosed. A condensing apparatus can include a condenser surface having a substrate and one or more layers of graphene. The substrate can be formed of nickel and a nickel-graphene surface composite layer can be formed. The substrate-graphene composite can be highly durable, hydrophobic, and resistant to fouling. Dropwise condensation can be induced.

Manufacturable metal-graphene interface for highly efficient and durable condensers

Microfluidic devices, along with methods of their fabrication, are provided. The microfluidic device can include a substrate defining a microchannel formed between a pair of side walls and a bottom surface and a plurality of nanotips positioned within the microchannel and proximate to each side wall such that a boundary layer is formed along each side wall between the plurality of nanotips and the side wall upon addition of a liquid into the microchannel.

Ultra-efficient two-phase evaporators/boilers enabled by nanotip-induced boundary layers

Microfluidic devices having superhydrophilic bi-porous interfaces are provided, along with their methods of formation. The device can include a substrate defining a microchannel formed between a pair of side walls and a bottom surface and a plurality of nanowires extending from each of the side walls and the bottom surface. For example, the nanowires can be silicon nanowires (e.g., pure silicon, silicon oxide, silicon carbide, etc., or mixtures thereof).

Microfluidic devices for the generation of nano-vapor bubbles and their methods of manufacture and use

Microfluidic devices, along with their methods of formation and use, are provided. The microfluidic device can include a substrate with a main channel and a first auxiliary channel defined in the substrate's surface. The main channel has a main width of about 1000 &#x3bc;m or less. The first auxiliary channel intersects with the main channel at a first aperture defined in a first side wall of the main channel. A second auxiliary channel can intersect with the main channel at a second aperture defined in a second side wall of the main channel. A plurality of main channels and respective auxiliary channel(s) can be included on the surface.
