A heat-dissipating device includes a housing having a first frame and a second frame, and a rotor disposed in the housing, wherein the first frame includes a bearing tube for accommodating a first bearing therein and the second frame includes a support for accommodating a second bearing therein so as to jointly support a shaft of the rotor. The heat-dissipating device utilizes a two-side way for securing its rotating shaft so as to enhance the stability and eliminate the vibration while operating at high rotation speed.

What is claimed is: 1. A heat-dissipating device, comprising: a housing having a first frame, a second frame, an air inlet and an air outlet; and a rotor disposed in the housing, wherein the first frame includes a bearing tube for accommodating a first bearing therein and the second frame includes
What is claimed is: 1. A heat-dissipating device, comprising: a housing having a first frame, a second frame, an air inlet and an air outlet; and a rotor disposed in the housing, wherein the first frame includes a bearing tube for accommodating a first bearing therein and the second frame includes a support for accommodating a second bearing therein so as to jointly support a shaft of the rotor, and a side wall extending from a periphery of the air inlet inwardly to define an air-gathering chamber in the housing; wherein the air-gathering chamber allows exterior airflow to enter the air inlet, through the air-gathering chamber and then exit from the air outlet. 2. The heat-dissipating device of claim 1, wherein the second frame further comprises an extending part axially extending toward a direction of the first frame to form an axially compressed airflow passage in the housing. 3. The heat-dissipating device of claim 1, wherein the rotor comprises a base, a hub, a first set of blades and a second set of blades. 4. The heat-dissipating device of claim 3, wherein the first set of blades extends downward from a periphery of the hub to a surface of the base and the second set of blades is disposed on the base. 5. The heat-dissipating device of claim 3, wherein the base, the hub, the first and second sets of blades are integrally formed as a single unit. 6. The heat-dissipating device of claim 3, further comprising a driving device disposed in the hub for driving the rotor to rotate. 7. The heat-dissipating device of claim 1, wherein the housing further comprises at least one air inlet formed on the second frame, and an air outlet defined after the first and second frames are assembled. 8. The heat-dissipating device of claim 1, wherein the sidewall has a flange at one end thereof extending radially to define an entrance of the air-gathering chamber. 9. The heat-dissipating device of claim 8, wherein the rotor has a plurality of blades extending toward the entrance of the air-gathering chamber for guiding the airflow into the air-gathering chamber. 10. The heat-dissipating device of claim 1, wherein the air-gathering chamber partially or completely overlaps an air passage through the rotor in height along an axis of the heat-dissipating device. 11. The heat-dissipating device of claim 1, wherein the air-gathering chamber has a cross-sectional area substantially identical to that of the air outlet of the housing. 12. The heat-dissipating device of claim 1, wherein the housing further comprises a plurality of air-guiding members arranged between the sidewall and the support for increasing a blast pressure of airflow passing through the heat-dissipating device. 13. The heat-dissipating device of claim 12, wherein the plurality of air-guiding members are fixed on the sidewall or the support. 14. The heat-dissipating device of claim 12, wherein the plurality of air-guiding members are shaped as strip, plate, curved, inclined or airfoil structures. 15. The heat-dissipating device of claim 12, wherein each of the plurality of air-guiding members has an inclined angle. 16. A heat-dissipating device, comprising: a housing having a first frame, a second frame, an air inlet, an air outlet and a plurality of air-guiding members; and a rotor disposed in the housing, wherein the first frame includes a bearing tube for accommodating a first bearing therein and the second frame includes a support for accommodating a second bearing therein so as to jointly support a shaft of the rotor; wherein the air-guiding members are arranged between a sidewall and the support for increasing a blast pressure of airflow passing through the heat-dissipating device, the air inlet is disposed at the second frame and the air-guiding members are located close to the air inlet. 17. The heat-dissipating device of claim 16, wherein the plurality of air-guiding members are fixed on the sidewall or the support. 18. The heat-dissipating device of claim 16, wherein the plurality of air-guiding members are shaped as strip, plate, curved, inclined or airfoil structures. 19. The heat-dissipating device of claim 16, wherein each of the plurality of air-guiding members has an inclined angle.
