Heat-dissipation device having dust-disposal mechanism

Abstract

A heat-dissipation device having a dust-disposal mechanism for removing dust from cooling metallic fins is provided, which includes a heat-conducting module and a dust-disposal mechanism. The heat-conducting module has a plurality of metallic fins arranged in the same direction and apart with a gap formed therebetween. The dust-disposal mechanism has a cleaning unit corresponding to the metallic fins so as to insert into the gap between the metallic fins and clear or absorb the dust accumulated on the metallic fins, thereby enhancing the cooling efficiency of the heat-conducting module.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of Taiwan application serial no. 95143314, filed Nov. 23, 2006. All disclosure of the Taiwan application is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a heat-dissipation device, and more particularly to a heat-dissipation device having a dust-disposal mechanism.[0004]2. Description of Related Art[0005]Recently, with the rapid progress of computer science and technology, the operation speed of the computer is improved increasingly, and the heat-generating rate of electronic devices in the computer host is increased accordingly. In order to prevent overheat of the electronic devices in the computer host, which may result in temporary or permanent failure of electronic devices, a sufficient heat-dissipation performance must be provided for the electronic devices in the computer.[0006]Generally speaking, a heat-di...

AI Technical Summary

Benefits of technology

[0016]The present invention adopts a cleaning unit having dust-disposal function to absorb or clear the dust on the metallic fins, such that the metallic fins of the heat-conducting module can keep clean. Therefore, 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.
