Heat-dissipation device with dust-disposal function

Abstract

A heat-dissipation device with dust-disposal function for removing dust from cooling metallic fins is provided, which includes a heat-conducting module and a vibrator. The heat-conducting module has a plurality of metallic fins, and the vibrator is directly or indirectly connected to the heat-conducting module to provide a vibrating source for the metallic fins, such that the dust accumulated on the metallic fins is shook off by vibration. The vibrator may be a piezoelectricity element or an eccentric motor. In addition, the vibrator may be an ultrasonic generator disposed near the heat-conducting module to provide a non-contact vibrating source for the metallic fins.

1 . A heat-dissipation device with dust-disposal function, comprising:
 a heat-conducting module, comprising a plurality of metallic fins arranged in parallel; and   at least one vibrator, connected to the heat-conducting module, for providing a vibrating source for the metallic fins.   
   
   
       2 . The heat-dissipation device with dust-disposal function as claimed in  claim 1 , wherein the vibrator comprises a piezoelectricity element which is deformed to generate the vibrating source.
