Device for Controlling Heat Dissipation Fan and Electronic Equipment

摘要

Disclosed are a device for controlling a heat dissipation fan and an electric equipment, to solve the problem that the reliability of speed-regulation control for a fan in the device for controlling a heat dissipation fan is relatively poor. The device includes a control system and a protection module, wherein the protection module includes a control signal output end for outputting a fan speed-regulation control signal to the fan, wherein, when a control system normal operation 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 fan speed-regulation control signal preset by itself so as to make the fan operate stably.

1. A device for controlling a heat dissipation fan, comprising: a first signal output end and a second signal output end of a control system for controlling a fan speed-regulation and monitoring the fan, which are respectively connected with a first signal input end and a second signal input end of a protection module, wherein the protection module further comprises a control signal output end for outputting a fan speed-regulation control signal to the fan, wherein the first signal is a control system normal operation indication signal, and the second signal is a fan speed-regulation control signal output by the control system, wherein when the control system normal operation indication signal is normal, the protection module controls the signal output end to output the fan speed-regulation control signal provided by the control system, otherwise the protection module outputs a fan speed-regulation control signal preset in the protection module to make the fan operate stably.
