摘要： A wind speed detecting circuit includes a heating unit, a first temperature sensor, a second temperature sensor, a control unit and a driving unit. The first temperature sensor detects a first temperature of an internal portion of an electronic device, thereby generating a first detecting signal. The second temperature sensor detects a second temperature of the heating unit, thereby generating a second detecting signal. The control unit generates a modulation signal according to the first detecting signal and the second detecting signal. In response to the modulation signal, the driving unit generates a driving signal to control operations of the heating unit, so that a temperature difference between the first temperature and the second temperature is maintained constant. A specified relation between the wind speed and the modulation signal facilitates discriminating whether a dust-proof element of the electronic device needs to be replaced.

摘要： A cooling device applied in a projection apparatus and the projection apparatus are provided. The projection apparatus comprises a first light source, a second light source, a third light source and the cooling device. The cooling device comprises an airflow guiding device and a fan. The airflow guiding device is adapted to define a first flow path and a second flow path. The first flow path has a first position, while the second flow path has a second position and a third position, correspondingly disposed with the first light source, the second light source and the third light source, respectively. The fan is adapted to generate airflow. The airflow is divided into a first airflow and a second airflow entering the first flow path and the second flow path, respectively. Thereby, the cooling device is capable of matching the heat dissipation requirements of the light sources and reducing the noise generated by the cooling device by using only one fan.

摘要： The heat-dissipating module of the electronic device comprises a fan, a first heat-dissipating component and a second heat-dissipating component. The fan is disposed on a first side of the casing, and the first heat-dissipating component is disposed on a second side of the casing and in heat contact with the electronic components for transferring heat generated by the electronic components to the casing. The second heat-dissipating component is disposed on an outer sidewall of the casing corresponding to the first heat-dissipating component and in heat contact with a system cooling system. Thereby, the heat generated by the electronic components is transferred to the second heat-dissipating component through the first heat-dissipating component and the casing, and then dissipated by the system cooling device.
