  • Enhanced evaporator surface
    Patent number: 4819719
    Abstract: An enhanced capillary assisted evaporative surface for use in heat transfer devices; such as, 2-phase mounting plates, heat pipes and collectors. Rectangular grooves are cut in a conductive substrate and then plated by vapor deposition. The process produces a necked-down opening in the groove and a dendritic surface improving both capillary pumping and heat transfer coefficients.
