HEAT DISSIPATION DEVICE INCORPORATING HEAT SPREADER

摘要

An exemplary heat dissipation device is adapted for dissipating heat generated by an electronic component mounted on a printed circuit board. The heat dissipation device includes a heat spreader and a fin set placed on the heat spreader. The heat spreader includes a base, a partition board hermetically placed on the base, and a covering plate hermetically placed on the partition board. A first chamber is defined between the base and the partition board, and a second chamber is defined between the partition board and the covering plate.
