Problems solved by technology

However, since the cooling chip is composed of a plurality of diodes connected in series, when the electronic device uses the cooling chip as the heat sink, the contact surface of the cooling chip may be damaged during the assembly process of the electronic device. It will be subjected to uneven pressure, which will cause the PN junction of these diodes to be destroyed, which will cause problems such as failure of the cooling chip or wrong drive control, and cause the electronic components to be dissipated because they cannot be cooled. fail

Abstract

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.

Description

technical field [0001] The present invention relates to a heat dissipation device and a detection method thereof, and in particular to a heat dissipation device capable of monitoring the health state of a radiator and a detection method thereof in real time. Background technique [0002] With the development of the technology industry, electronic devices such as projectors, notebook computers (Notebook, NB), tablet computers (Tablet PC) and smart phones (Smart Phone) have been popularized in the consumer market. With the continuous improvement of the operating performance of the electronic device, the heating power of the electronic components in the electronic device is also continuously increased. [0003] In this case, known technologies generally provide heat sinks (eg, thermoelectric coolers (TECs), fans or fins, etc.) in electronic devices to dissipate heat from electronic components that generate heat. However, since the cooling chip is composed of a plurality of dio...
