Abstract

Disclosed are a device for controlling a heat dissipation fan and electronic equipment, with the aim of solving the problem that the reliability of speed-regulation control for a fan in the heat dissipation fan control device is relatively poor. The device comprises a control system and a protection module, wherein the protection module comprises a control signal output end for outputting a fan speed-regulation control signal to the fan; when the control system operates normally and an indication signal is normal, the control signal output end of the protection module outputs the fan speed-regulation control signal provided by the control system, otherwise the protection module outputs a self-pre-set fan speed-regulation control signal so as to make the fan operate stably; and thus the protection module outputs the self-pre-set fan speed-regulation control signal to make the fan operate stably when the control system does not operate normally, so that the reliability of speed-regulation control for the fan is enhanced, and the reliability and stability of the heat dissipation fan system can be improved.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a cooling fan control device and electronic equipment. Background technique [0002] Nowadays, most electronic devices such as computers and communication devices are equipped with cooling fans to meet the cooling requirements of the system and ensure the stable operation of the system. At present, when the cooling fan control device adjusts and monitors the fan speed, it usually directly controls the fan speed through the control signal. This kind of direct electrical connection with the fan directly through the control signal has considerable hidden dangers and shortcomings. When the device is unstable or faulty when the device is powered on, the fan cannot be effectively controlled, which will cause the fan to be uncontrollable, such as stopping or running at a low speed, which cannot satisfy the heat dissipation of the device, resulting in overheating and damage t...
