Abstract
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.
Claims19
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.
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.
