  • Instantaneous fan stopping method and structure thereof
    Publication number: 20050184692
    Abstract: The present invention provides an instantaneous fan stopping method and structure thereof. The method and structure can eliminate the inertial rotating state of the fan when the power supplied to the fan is cut off. In accordance with the present invention, a closed circuit is formed between the two terminals of the coil used to drive the fan. When the closed circuit is formed, the inertial rotation of the fan can generate an induced current in this coil, which, in turn, generates a magnetic force to stop the fan.

  • Heat dissipation device and fan module thereof
    Publication number: 20050174734
    Abstract: A heat dissipation device and fan module. The fan module is fixed to a fan tray, which has a track with a first engaging portion. A securing member is disposed on a shield, comprising a second engaging portion. The second engaging portion enters the first engaging portion, fixing the fan module to the fan tray. An actuator connects the securing member and the shield. When external force deforms the actuator, the securing member deforms therewith, withdrawing the second engaging portion from the first engaging portion.
