Abstract
A heat spreader includes a base with a cavity defined therein and a cover mounted on the base to thereby hermetically seal the cavity of the base. A predetermined quantity of working liquid is contained in the cavity. The heat spreader further includes a first wick structure formed on an inner surface of the base, a second wick structure formed on an inner surface of the cover and a third wick structure embedded in the first wick structure. The first and second wick structures are made of metal mesh, carbon nanotube array or bundle of fibers and the third wick structure is made of sintered metal powder. In use, the third wick structure is positioned corresponding to a heat generating electronic component.
