專利摘要：
An active heat-dissipation system (10) for a base station of a communication system includes a measuring module (4), configured to detect a temperature sensing signal of the base station; a controller (1), configured to receive the temperature sensing signal detected by the measuring module (4) to set a preset temperature signal, to generate a difference between the temperature sensing signal and the preset temperature signal and a time derivative of the difference, and to output a control signal according to the difference and the time derivative of the difference based on a control program; and a power module (2), configured to receive the control signal and output an electrical signal to a heat-dissipation module (3) according to the control signal, such that the heat-dissipation module (3) performs a heat-dissipation process for the base station according to the electrical signal.
