Fan system

The utility model provides a fan system which comprises a first fan and a second fan, and the first fan is provided with a first fan wheel and a first controller. The second fan is connected with thefirst fan and provided with a second fan wheel and a second controller. When the state signal of one of the first fan and the second fan is abnormal, the fan is started; and the other normal fan accelerates to operate at a rotating speed greater than or equal to 110% of the full-working-cycle speed parameter so as to compensate the air volume, so that a heat source of the electronic element or theelectronic device can be dissipated, the electronic element or the electronic device cannot be shut down or malfunctioned, and the normal operation of the electronic element or the electronic deviceis ensured. 本实用新型提供了一种风扇系统，该风扇系统包括：一第一风扇及一第二风扇，该第一风扇具有一第一扇轮及一第一控制器。该第二风扇连接该第一风扇，该第二风扇具有一第二扇轮及一第二控制器。当该第一风扇或该第二风扇其中之一的状态讯号为异常时，另一正常的风扇则以大于或等于全工作周期速度参数110％的转速加速运转，以补偿风量，使得电子元件或电子装置的热源能够散逸，而不会使电子元件或电子装置产生当机或误动作的情形，确保电子元件或电子装置运作正常。
