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 d...

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 accumulate...

Embodiment Construction

[0022]Referring to FIG. 1, a schematic view of a heat-dissipation device with dust-disposal function according to an embodiment of the present invention is shown. The heat-dissipation device 100 mainly includes a heat-conducting module 110 and at least one vibrator 120, and the heat-conducting module 110 is used to dissipate heat of electronic devices with high heat-generating rate, so as to reduce the operating temperature of the electronic devices in a system. The heat-conducting module 110 is generally made of metallic material with high heat conductivity such as Cu and Al, and is disposed on the electronic devices and connected to an air-cooling heat-dissipation module or water-cooling heat-dissipation module in the system, so as to achieve the purpose of heat dissipation.

[0023]In this embodiment, the heat-conducting module 110 includes a plurality of metallic fins 112 arranged in parallel, and the metallic fins 112 in regular arrangement are stacked with a gap existing therebet...

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.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of Taiwan application serial no. 95143313, 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 with dust-disposal function.[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-dissipa...
