Heterogeneous Surfaces

US Patent Pending

Applications

  • Heat exchangers
  • Power plants
  • Solar thermal conversion systems
  • Heat pipes

Problem Addressed

Superhydrophobic surfaces have received significant interest for drop-wise condensation to increase the efficiency of energy applications. However, nucleation densities on regular superhydrophobic surfaces are difficult to achieve due to the high energy barrier for nuclei formation; hence enhancement of heat transfer can be limited.

Technology

 This invention is a superhydrophobic surface with increased nucleation density comprising  a patterned substrate and a material infused into regions of the substrate.

Advantages

  • Increased nucleation density
  • Enhancement of heat transfer
