Abstract
A heat-dissipating device includes a housing having at least one opening, and a rotor disposed in the housing and having a base, a hub, a first set of blades disposed around the hub, and a second set of blades disposed on the base for increasing air volume and stabilizing a blast pressure of airflow passing through the heat-dissipating device.
Claims22
A heat-dissipating device, comprising:
- a housing having at least one opening;
- a rotor disposed in the housing and having a base, a hub;
- a first set of blades disposed around the hub, and a second set of blades disposed on the base;
- and
- a driving device disposed inside the hub,
- wherein the housing has a sidewall and a flange radially extending from the bottom of the sidewall to define an entrance of an air-gathering chamber, the entrance is between the flange and the bottom of the housing, and the air-gathering chamber is between the sidewall and a peripheral wall of the housing, and
- wherein an outermost end of the flange is vertically aligned with an outermost end of at least one of the first set of blades and the second set of blades.
