Vapor chamber that utilizes a capillary structure and bumps to form a liquid-vapor channel

A vapor chamber, comprising:

• a first panel defining an evaporation region, a thermal insulation region and a condensation region, said thermal insulation region being adjacent to said evaporation region and said condensation region respectively, said evaporation region and said condensation region being spaced from each other;
• a second panel joined to said first panel with an enclosed accommodation space defined therebetween;
• a capillary material made in the form of a flake and located in said accommodation space;
• and
• a working fluid filled in said accommodation space;
• wherein:
• said first panel comprises a plurality of first bumps located on a panel surface thereof within said accommodation space and distributed in said evaporation region, said thermal insulation region and said condensation region and abutted against said capillary material;
• said capillary material comprises a hollow portion located in said thermal insulation region to expose a part of said first bumps and to define a vapor channel therein, said capillary material having a part thereof located in said thermal insulation region to form at least one liquid channel;
• said second panel comprises a plurality of second bumps located on a panel surface thereof within said accommodation space, said second bumps being disposed in said hollow portion to abut against said first bumps.
