Abstract
A vapor chamber heat sink attached to a heat-generating electronic component includes a base (10) defining an opening therein. A plurality of fins (20) is mounted on the base. A heat pipe (30) thermally connects the electronic component and the fins. The heat pipe comprises a plate-type lower portion (32) contacting a bottom surface of the base and a bottom surface (22) of the fins and overlaying a top surface of the electronic component, a plate-type upper portion (34) parallel to the lower portion contacting a top surface (24) of the fins, and a connecting portion (36) interconnecting opposite two ends of the lower and upper portions. The heat pipe is configured in such a manner so as to enhance contact area and thermal conductivity between the heat pipe and the electronic component and between the heat pipe and the fins.
