Abstract: A heat dissipation apparatus is disclosed. In the dissipation apparatus, a support is mounted to a circuit board, and an assembly opening on a bearing portion in the support is configured to accommodate a heat source on the circuit board. A heat sink is disposed on the bearing portion of the support, and a heat conducting surface of the heat sink can penetrate the assembly opening, to be attached to the heat conducting surface of the heat source. A peak-valley structure in an elastic component is disposed on a mounting surface of the heat sink as a force-applying portion, and two ends of the elastic component exceed an edge of the heat sink and are mounted to the support as mounting portions. At least one elastic component can provide, to the heat sink by using the peak-valley structure, pressure to tightly attach the heat sink to the heat source.
