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.

AI Technical Summary

Benefits of technology

[0016]The present invention adopts the heat-dissipation device with dust-disposal function, and thus the dust on the metallic fins is shook off by vibration of the vibrator. Since the heat-dissipation device can automatically clean the dust on the metallic fins periodically or nonperiodically, the airflow generated by the fan can quickly remove the waste heat from the metallic fins, thereby significantly improving the heat-dissipation capability of the heat-dissipation device.

Problems solved by technology

It should be noted that after the heat-dissipation device is used for a long time, dust in the air is gradually accumulated between the metallic fins of the cooling fins.

If not being cleaned, excessive dust accumulated on the metallic fins may result in that the airflow blown by the fan cannot remove the waste heat from the cooling fins easily, thereby significantly reducing the heat-dissipation capability of the heat-dissipation device.
