| 摘要 |
The invention relates to cooling techniques for portable devices such as, for example, mobile telephones. In one implementation, a portable device (100) comprises one or more printed circuit boards ("PCBs" 208, 210) supporting multiple heat-generating components (214), an airflow generator (112) adapted to generate an airflow (300) internally in the portable device, and a heat sink element (212) thermally connected to the heat-generating components (214), wherein the heat sink element (212) is adapted to receive heat from the heat-generating components (214) for dissipation by the airflow (300).
