Abstract:
1. A method of manufacturing heat-dissipation unit with heat-dissipation microstructure, comprising the steps of: providing a heat-dissipation unit that includes an internal chamber; forming a wick structure on an inner surface of the internal chamber of the heat-dissipation unit; coating the wick structure with an oxide nano thin film; drying the wick structure after the wick structure has been coated with the oxide nano thin film; sintering the wick structure after the wick structure has been coated with the oxide nano thin film and dried; after sintering the wick structure, providing a vacuum within the internal chamber of the heat-dissipation unit; and injecting a working fluid into the internal chamber of the heat-dissipation unit and sealing an open end of the heat-dissipation unit.
