Abstract
Heat transfer systems and methods are provided. The heat transfer system includes an evaporator section integrated with or thermally joined to a heat dissipating system. The evaporator section is connected to a condenser section by a conduit. Together, portions of the evaporator section, the condenser section, and the conduit form a closed volume containing a heat transfer fluid. A superhydrophobic surface is present on at least a portion of the condenser section forming a part of the closed volume. The superhydrophobic surface can include a plurality of carbon nanotubes. The carbon nanotubes can be provided as a forest of carbon nanotubes extending from a rough surface.
