Abstract
A temperature control device comprises a fan, a temperature sensor, a modeling circuit and a PID controller, with the PID controller connected with the fan, the temperature sensor and the modeling circuit. The fan drives airflows for controlling the temperature of a controlled region. The temperature sensor is disposed in the controlled region and obtains a detected temperature indicating the temperature of the controlled region. The modeling circuit obtains at least one cooling parameter group based on a transfer function. The PID controller controls the fan based on an initial parameter group when the detected temperature is lower than a first temperature, and controls the fan based on said at least one cooling parameter group when the detected temperature is equal to or higher than the first temperature. The initial parameter group comprises initial parameters, with the value of each of the initial parameters equal to a preset value.
