Abstract: A heat dissipation apparatus applied to a terminal device includes a phase change material (PCM) and a heat transfer unit. The heat transfer unit is in contact with the PCM to conduct heat of the terminal device to the PCM. Because the PCM maintains a temperature substantially unchanged during a phase change, a temperature of the heat dissipation apparatus is not excessively high while heat is absorbed.
