Patent ID: 8590154

Claim:
A vapor chamber manufacturing method, comprising: preparing raw metal material for the vapor chamber, cutting said raw metal material to predetermined dimensions and punching the raw metal material to form a metal tube, and inserting a mold rod matched with an internal diameter of said metal tube into a cavity of said metal tube; filling the cavity of said metal tube with a raw powder screened and sintering said metal tube after filling, and removing said mold rod from said sintered metal tube; pressing said metal tube to a flat shape having two openings and filling the cavity of said pressed metal tube with a supporting structure; reserving one portion of one opening of said pressed metal material as a fluid injection port and pressing the rest of the opening to seal the one opening except the portion of the opening reserved as a fluid injection port forming a reserved opening; injecting a quantified amount of working fluid into the cavity through said fluid injection port to form a semi-finished vapor chamber; and preparing a vacuum chamber comprising a vacuum pumping device, a pressing device, a seal welding device, and an observation window for an operator to observe internal conditions in the vacuum chamber, and forming a finished vapor chamber by placing at least one semi-finished vapor chamber into said vacuum chamber, and pressing and sealing said fluid injection port of said semi-finished vapor chamber.
