  • Publication number: 20050237491
    Abstract: An optical projection module and a fan assembly thereof. A casing comprises at least one heat-dissipation vent. An image projection module is disposed in the casing to create an image. A light source provides light to the image projection module. A fan disposed in the heat-dissipation vent comprises a hub and a plurality of primary blades encircling the hub. Adjacent primary blades overlap in an axial direction. A region formed by the primary blades and the hub blocks a light from transmitting through the heat-dissipation vent.

  • Patent number: 6951449
    Abstract: A heat-dissipating device is provided for generating primary airflow to dissipate heat generated by external heat sources as well as secondary airflow to dissipate heat generated from the interior of the heat-dissipating device. The heat-dissipating device includes a primary fan and a secondary fan coupled with a shaft of the primary fan. The secondary fan is rotated along the shaft to generate the secondary airflow and dissipate heat generated by the heat-dissipating device per se. Thus, the operation temperature of the heat-dissipating device can be lowered to increase its life span.

  • 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.
