Abstract
A heat dissipation device includes a base, a fin assembly mounted on a top surface of the base, and a heat absorber arranged at a bottom surface of the base. The bottom surface of the base defines a recess corresponding to the heat absorber. The heat absorber is embedded in the recess. A fixing plate is positioned at the bottom surface of the base to cover the recess and define a sealed/airtight cavity between the fixing plate and the base. A top end of the heat absorber is received in the sealed/airtight cavity. A top end of the heat absorber extends through the fixing plate to expose out of the sealed/airtight cavity. A flexible sheet is totally received in the sealed/airtight cavity to buffer a stress generated by assembling the heat dissipation device with external elements.
