Description

    CROSS-REFERENCE TO RELATED APPLICATION
  • 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
  • 1. Field of the Invention
  • The present invention relates to a heat-dissipation device, and more particularly to a heat-dissipation device with dust-disposal function.
  • 2. Description of Related Art
  • 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.
  • Generally speaking, a heat-dissipation device mainly includes a fan, cooling fins, and a heat pipe. The cooling fins are disposed at an air outlet of the fan, and are connected to the heat pipe, so as to absorb the waste heat conducted by the heat pipes. The cooling fins include a plurality of metallic fins arranged in parallel with a certain gap existing between adjacent metallic fins, so as to dissipate the waste heat to air through convection. Therefore, when the fan is operating, a cooling airflow flows to the cooling fins via the air outlet and passes the gaps between the metallic fins, so as to dissipate the waste heat to the outside of the case through convention, thereby lowering the operating temperature of the internal electronic devices.
  • 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.

    •  DESCRIPTION OF EMBODIMENTS
  • 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.
  • 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 therebetween, so as to increase the heat-dissipation area of the heat-conducting module. The metallic fins 112 are, for example, disposed at an air outlet 132 of a fan module 130, such that a cooling airflow generated by the fan module 130 can easily pass through the gaps between the metallic fins 112. In addition, the heat-conducting module 110 further includes a heat pipe 114 connected between the metallic fins 112 and a heat source (e.g., an integrated circuit chip) 10. A capillary structure is provided on an inner pipe wall of the heat pipe 114, such that the cooling water flows in the heat pipe 114 by capillary phenomenon, and the waste heat generated by the heat source 10 at one end of the heat pipe 114 is conducted to each metallic fin 112 at the other end of the heat pipe 114, so as to achieve the purpose of reducing the temperature of the heat source 10.
  • It should be noted that the vibrator 120 can generate a vibrating source for the heat-conducting module 110 to dispose dust, such that excessive dust will not be accumulated on the heat-dissipation surface of the metallic fins 112 and/or the heat pipe 114. As shown in FIG. 1, the vibrator 120 can be directly disposed on the heat-conducting module 110, so as to generate a contact vibrating source. With the vibration of the vibrator 120, the metallic fins 112 suffer a shaking force to shake off dust on the metallic fins 112. In this embodiment, the dust tends to be accumulated between the metallic fins 112 and/or between the metallic fins 112 and the heat pipe 114 after a period of time, especially on the end portions of the fins near the fan module 130, and thus the vibrator 120 is preferably disposed near the end portions of metallic fins 112, so as to generate the maximum vibration effect. However, the drawings of this embodiment are not intended to limit the present invention, and other preferred arrangements obtained from design, experiment or simulation can be applied in the present invention. In addition, the number of the vibrator 120 can be one or more optionally.
  • Moreover, the fan module 130 is disposed at one side of the metallic fins 112. With a centrifugal force generated by the rotation of blades 134, the external cold air enters via an air inlet (not shown, in the same direction as the rotation axis of the blades 134), and the air around the blades 134 flows along the rotation direction, and flows to the metallic fins 112 arranged in the same direction of the airflow via the air outlet 132. In this embodiment, the air inlet is vertical to the normal vector of the air outlet 132, but in another embodiment, the air inlet can be in parallel to the normal vector of the air outlet 132.
  • Referring to FIG. 2, the vibrator 120 has, for example, a piezoelectricity element 120 a, which is configured to be disposed on the heat-conducting module 110 of the FIG. 1. The piezoelectricity element 120 a is deformed by the volume change under a piezoelectric effect, and thus when a high-frequency voltage signal is input from the exterior of the piezoelectricity element 120 a, a high-frequency mechanical vibration is generated, thereby generating a vibrating source. Furthermore, referring to FIG. 3, the vibrator 120 has, for example, an eccentric motor 120 b. The eccentric motor 120 b has an eccentric element 122, for example, an eccentric cam or an eccentric shaft. When power energy is input from the exterior of the eccentric motor 120 b, an eccentric vibrating source is generated by the high-speed rotation of the eccentric element 122, such that the dust accumulated on the metallic fins 112 cannot be attached thereon and is shook off.
  • In addition to the implementation of the piezoelectricity element and eccentric motor to generate contact vibrating source, the vibrator 120 can be further disposed near the heat-conducting module 110 in a non-contact manner to generate a non-contact vibrating source. Referring to FIG. 4, the vibrator is, for example, an ultrasonic generator 120 c, and the generated ultrasonic wave is transmitted to the heat-conducting module 110 through the air. With the vibration of the air, the dust cannot be attached on the surface of the metallic fins 112, thus achieving the dust-disposal efficiency. The frequency of the ultrasonic vibrating source is beyond the frequency that can be received by human ear, so no noise is sensed by the human.
  • Moreover, referring to FIG. 1, the vibrator 120 operated together with a controller 140 can provide functions such as automatic timing, turning on, and turning off functions, such that the vibrator 120 is set to automatically turn on when the heat-dissipation system or the electronic device is turned on, and to automatically turn off when the heat-dissipation system or the electronic device is turned off. Definitely, in the present invention, a hot key or a built-in dust-disposal managing unit may be used to inform the user, such that the user may choose the opportunity to dispose dust. In addition, the vibrator 120 together with a timer (not shown) can calculate the time at which the vibrator 120 provides the vibrating source, such that the controller 140 can set the working time of dust-disposal.
  • In view of the above, the present invention provides a heat-dissipation device with dust-disposal function after research and development, and simulation, which can reduce the dust attached on the heat-conducting module and provides a perfect dust-disposal efficiency for metallic fins (cooling fins) arranged in parallel, so as to prevent excessive dust from being accumulated on the metallic fins near the air outlet of the fan module and thus influencing the heat-dissipation performance of the metallic fins. Meanwhile, the cooling airflow generated by the fan module can easily take away the waste heat on the metallic fins, and the heat-dissipation capability of the heat-dissipation device is improved accordingly.
  • It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
