| Zusammenfassung: | A heat dissipation system comprises a fan motor, at least two controllers, a signal generator and a signal converter. The controllers are electrically connected with each other, and one ends of the controllers are electrically connected to the fan. The controllers generate an enable signal according to a feedback signal of the fan. The signal generator is electrically connected with the other ends of the controllers, and generates a control signal according to the enable signal of the controllers. The signal converter is electrically connected between the signal generator and the fan, and generates a driving signal to drive the fan according to the control signal of the signal generator. When one of the controllers is out of order, the others can maintain the normal operation of this heat dissipation system. In addition, this invention can also comprise at least two signal generators or at least two signal converters to get better operation stability. |
