Integrated heat dissipation module structure

An integrated heat dissipation module structure, comprising:

• a metallic top cover, including oppositely an outer heat-dissipating surface and an inner condensation surface, the outer heat-dissipating surface having a plurality of columnar heat dissipation structures protruding therefrom, the inner condensation surface being surrounded by a top frame with a predetermined height, the top frame being furnished with an upper communicative groove, the inner condensation surface having thereon a plurality of top grooves parallel to each other;
• a metallic bottom cover, including oppositely an outer heat-absorption surface and an inner evaporation surface, the outer heat-absorption surface having thereon a screw hole for locking at least one heat-generating element, the inner evaporation surface being surrounded by a bottom frame with another predetermined height, and the bottom frame is furnished with a lower communicative groove, the inner evaporation surface having thereon a plurality of bottom grooves parallel to each other, a plurality of supporting structures protruding therefrom and disposed individually among the plurality of bottom grooves, and a screw-hole protrusion corresponding to the screw hole, the screw-hole protrusion recessed into the outer heat-absorption surface toward the inner evaporation surface and protruding from the inner evaporation surface but not penetrating through, the screw-hole protrusion being not higher than the supporting structures;
• a working space, being an airtight space formed by engaging the top frame of the metallic top cover and the bottom frame of the metallic bottom cover with the inner condensation surface of the metallic top cover to face the inner evaporation surface of the metallic bottom cover, the plurality of top grooves to overlap individually the plurality of bottom grooves, the plurality of supporting structures protruding from the inner evaporation surface to contact individually at the inner condensation surface among the plurality of top grooves and providing support to the working space;
• a vacuum channel being formed by connecting spatially the upper communicative groove and the lower communicative groove so as provide a channel for vacuuming the working space;
• a plurality of capillary structures, disposed individually inside the plurality of bottom grooves or both top grooves and bottom grooves;
• and
• a working fluid, being in the working space and the plurality of capillary structures;
• wherein the metallic top cover and the plurality of columnar heat dissipation structures are part of a single body made of metal, and the metallic bottom cover, the plurality of supporting structures, and the screw-hole protrusions are part of another single body made of metal.
