Heat dissipation device and detection method thereof

The invention discloses a heat dissipation device and a detection method thereof. The heat dissipation device comprises a controller, a driver, a temperature sensor and a heat dissipation device. The temperature sensor generates a temperature sensing signal according to a reference temperature value. The controller generates a control signal according to the temperature sensing signal. The driver generates a driving signal having a direct current portion and an alternating current portion according to the control signal. The heat dissipation device generates a feedback signal according to the driving signal. The controller calculates the impedance of the heat dissipation device according to a to-be-detected signal, and obtains a heat dissipation state signal according to the impedance of the heat dissipation device. According to the heat dissipation device and the detection method thereof, the health state of the radiator can be monitored in real time. 一种散热装置及其检测方法。散热装置包括控制器、驱动器、温度感测器以及散热器。温度感测器依据参考温度值以产生温度感测
