1. A thermal management method for multiple heat sources applicable to a wireless communication apparatus having multiple heat sources; wherein the wireless communication apparatus comprises at least a wireless communication module, a heat source set, a thermally conductive assembly, a heat-dissipating fin assembly, and a cooling fan, the thermally conductive assembly is connected to the wireless communication module and the heat source set, the heat-dissipating fin assembly is connected to the thermally conductive assembly and is configured corresponding to the heat source set or the wireless communication module, the cooling fan normally operates at a first rotational speed to apply forced air cooling to the heat-dissipating fin assembly, and the thermal management method comprises:
setting a first threshold temperature, a second threshold temperature, and a third threshold temperature, wherein the third threshold temperature is greater than the second threshold temperature, and the second threshold temperature is greater than the first threshold temperature;
performing a system detection, wherein the system detection comprises detecting temperature values of the wireless communication module and the heat source set;
determining whether the temperature value of the wireless communication module is greater than the first threshold temperature;
when the temperature value of the wireless communication module is greater than the first threshold temperature, determining a second rotational speed greater than the first rotational speed, and controlling the cooling fan to operate at the second rotational speed to apply forced air cooling to the heat-dissipating fin assembly;
determining whether the temperature value of the wireless communication module is greater than the second threshold temperature;
when the temperature value of the wireless communication module is greater than the second threshold temperature, decreasing power consumption of the heat source set;
determining whether the temperature value of the wireless communication module is greater than the third threshold temperature; and
when the temperature value of the wireless communication module is greater than the third threshold temperature, executing an event trigger.
