Abstract: A heat dissipation method applied to an electronic device including an electronic component is provided. The heat dissipation method includes: sensing a temperature of an electronic component by the temperature sensor; determining whether the temperature of the electronic component is larger than a threshold temperature; determining a rotation speed rank corresponding to a basic rotation speed and intermittently accelerating the basic rotation speed in the rotation speed rank while the sensed temperature of the electronic device is larger than a threshold temperature.

Abstract: An electronic device includes an upper cover, a lower cover combined with the upper cover, and a heat conducting pillar. An accommodating space is formed by the upper cover and the lower cover. The heat conducting pillar is disposed in the accommodating space and physically connected with the upper cover and the lower cover to balance the temperature of the upper cover and the lower cover.

Abstract: A heat dissipation apparatus with an antenna is provided. The heat dissipation apparatus includes a housing, a heat-insulation structure, a fan and an antenna. The heat-insulation structure is disposed on the housing and the heat-insulation structure has a plurality of heat dissipation holes. The fan is disposed in the housing and an air exhaust channel is formed between the fan and the heat-insulation structure. The antenna is disposed in the air exhaust channel.

Abstract: A portable electronic system includes a portable device and a mobile device. The portable device includes a base, a bearing seat, and a connecting element. The base includes a fan and at least one first opening. The bearing seat includes at least one second opening. The connecting element connects the base and the bearing seat and includes a passage. The mobile device is detachably disposed at the bearing seat and includes at least one third opening. The base and the mobile device have corresponding passage and openings to bring heat airflow from inside of the mobile device to outside of the mobile device.
