Abstract: In the past, several microchannel configurations were developed to realize two-phase cooling for high-power electronics, but these were limited to small devices with sizes at ˜cm length. It has been a challenge to implement effective two-phase cooling to large devices with a length of ˜10 cm due to notorious scaling effects. Here, we devised a novel channel configuration to achieve effective two-phase cooling on devices with an area of ˜10 cm by ˜5 cm or larger, which is the prevailing size of major commercial electronics and power electronics devices. In a lab environment, we demonstrated that the novel channel configuration can meet their cooling needs.

Abstract: 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.
