Manufacturing Method for Producing Wick Structures of a Vapor Chamber by Using a Powder Thermal Spray Gun

摘要

Simplifying a manufacturing method for producing wick structures of a vapor chamber includes providing a metal lid, providing a powder thermal spray gun to generate a high temperature blaze to melt a sprayed first powder into a melting surface status, and directly spraying the first powder with the melting surface status on an inner surface of the metal lid to form a first wick structure with a porous status over the inner surface of the metal lid. The manufacturing method further includes putting a cooling system outside the metal lid to keep the metal lid low temperature.
