Abstract
A heat-dissipating module includes a heat sink and a fan device. The fan device may be disposed on the heat sink, or inserted into the heat sink to reduce the height. The fan device includes a first rotor blade and a second rotor blade. The first rotor blade and the second rotor blade are connected in series. The rotation speed of the first rotor blade is controlled by a first control circuit, and the second rotor blade is controlled by the second circuit. Thus, the second control circuit increases the rotation speed of the second rotor blades when the first rotor blades is failed.
Claims20
A heat-dissipating module comprising:
- a heat sink having a plurality of cooling fins;
- and
- a fan device, having a base, an outer frame, a first rotor blade and a second rotor blade, and disposed on the heat sink, wherein the first blade and the second rotor blade are connected in series, and are surrounded by the outer frame, and the base includes a first support and a second support opposite to the first support, and the first support is coupled to the first rotor blade and the second support is coupled to the second rotor blade.
A heat-dissipating module comprising:
- a heat sink having a plurality of cooling fins, wherein the cooling fins define a space;
- a base disposed in the space and supported by cooling fins;
