Abstract
A vapor chamber having a composite supporting structure includes a flat sealed casing; a wick structure, a working fluid and a composite supporting structure. The composite supporting structure has a waved supporting rack and at least one supporting pillar. The waved supporting rack is configured to support upper and lower inner walls of the flat sealed casing. The waved supporting rack has plural separated channels for allowing vapor of the working fluid to flow through. Both ends of the at least one supporting pillar are respectively connected to the flat sealed casing or the wick structure. With this arrangement, compressive strength and tensile strength of the vapor chamber can be increased simultaneously without obstructing the circulation of liquid/vapor phases of the working fluid and reducing the thermal-conducting efficiency thereof.
