Back-up heat dissipating system has first controller which outputs signal to second controller for driving second rotor device to rotate at relatively higher speed, when first rotor device is failed

摘要

The back-up heat dissipating system includes a first controller which outputs a signal to a second controller for driving a second rotor device to rotate at a relatively higher speed, when a first rotor device is failed. The rotor devices are coupled in series along the axial direction of a main frame.
