Patent Images
1. A heat dissipation structure comprising:
- a copper clad sheet comprising a plurality of containing grooves and a plurality of ribs round each containing groove, each of the plurality of containing grooves formed by stamping, the copper clad sheet comprising an insulation layer and a copper clad layer attached on the insulation layer, wherein a surface of the copper clad layer facing away from the insulation layer forms an inner surface of the plurality of containing grooves, the insulation layer follows a contour of the copper clad layer and has a same shape as that of the copper clad layer;
a plurality of bond blocks arranged on the ribs;
a cover being fixed on the copper clad sheet with the containing groove using the bond blocks, the cover sealing the plurality of containing grooves to form a plurality of a sealed cavities; and
a phase-change material contained in the sealed cavity and configured to absorb and transfer out heat generated by components.

Abstract
An ultrathin heat dissipation structure includes a copper clad sheet, a cover, a number of bond blocks, and a phase-change material. The copper clad sheet is given containing grooves and a number of ribs round each containing groove. The containing grooves are formed by stamping. The copper clad sheet includes an insulation layer. The copper clad layer is inner surface of the containing groove. The bond blocks are arranged on the ribs and cover is pressed to the stamped copper clad sheet and secured using the bond blocks. The containing grooves form sealing cavities and the phase-change material in the sealed cavity gathers and transfers out any heat generated by components.
