Field of the Invention The present invention relates to a heat sink, and more particularly to a heat sink for use in a portable electronic device. [Prior Art] With the rapid development of electronic technology and consumers paying more attention to the light and portable of consumer electronic products, today's electronic products such as notebook computers and ultra-portable computers (ultra mobile personal c〇mpmer) Guess, pDA and other portable models have been developed to miniaturization. For users who need to be constantly outside, portable electronic products have become more portable, greatly improving the convenience of use. For example, in the case of ultra-portable computers, the operating speed of the electronic components of the ribbed computer is increased by the speed of the two-speed j plus the electronic component _, which causes the heat generated per unit area to be dissipated (6), and the heat is dissipated in time. Seriously affect the flexibility and efficiency of the power station, and even cause the life of the computer device to know or know the bad results. In order to solve the problem of installing a cooling fan inside the bulk device of the portable computer device, the method of electricity is tied to the computer. The ambient temperature inside the device. However, it is desirable to reduce the necessary circuit wiring and related electrical shortness of the computer at the same time, deducting::;-External two:=:_ The circuit inside the computer device must be matched with the fan. 5 200910054 Change the original tree (4), so that the county can be improved, and the electric service will increase with the fan, and the thin wire will be reduced. The electric service (4) touches the circuit wiring and the volume, and selects the micro-wei panel fan, and the heat dissipation efficiency fears the method to meet the heat dissipation requirements of the high-heat micro-components. —f The air that the professional hot fan guides during operation will The outer shell and the flow member are mutually screaming--(four) rate (four) sound. The thin and light Wei's super-featured 'built-in' and heat-dissipating the fan generated by the fan (four) sound will not suffer from too much copy, but can be directly transmitted to the device External, causing phase #重(四)音问题. This noise problem is one of the problems that the field technicians want to overcome. [Summary of the Invention] Xinfang, above (4), the present invention provides __ kinds of heat sinks, thereby improving It is applied to the electronically-acceptable (4) loose-wire arrangement, the circuit layout of the rib-mounted ribs, the g& setting of the electronic components, the dissipation of the internal space due to the dispersion, the heat dissipation efficiency is poor, and the noise generated is too large.

The shooting, the mosquito section is set in the electricity: the reduced section of the board remains suspended and corresponds to the coil, and the movable section is excited by the magnetic force of the magnetic field. And the heat-dissipating device disclosed in the present invention is light and thin, and can be modularized for electrical installation to make the portable electronic device more compact. In addition, the oscillating film system By using 200910054, the heat-conducting airflow is generated by the action of the needle, which not only improves the problem of excessive (four) sound generated by the conventional cooling fan, but also greatly reduces the amount of power required for the operation. The above description of the implementation of the ribs and the following descriptions of the present invention are used to explain the principles of the invention and to provide further explanation of the scope of the singularity. [Embodiment] According to the transcript of the present disclosure, in addition to the heat generated by the electronic device, the electronic device includes, but is not limited to, an ultra-portable computer (uMpc), a personal electric t-note computer, a portable electronic device, etc. Jian. Machimoto said in detail: = Superb_ is the preferred embodiment of the present invention. However, the drawings are for illustrative purposes only and are not intended to limit the invention. Please refer to the schematic diagrams of "Figure 1A" and "Figure 1B". As shown in the figure, the heat-dissipating package of the first embodiment disclosed in the present invention is disposed in the electronic gathering, and the sub-accepting-periodic power source is used to dissipate the heat energy generated by the ^20 on the Wei plate. The periodic power source may be an AC power source having an intermittent period of a plurality of power supply H and an unpowered interval, such as a sine wave crane, / the heart has a fixed current or a non-fixed help * _ Fixed period non-solid & complement, can also find phase P, signal; periodic power supply through the basic wheel / wheel Input / 〇utput System, coffee §) control its ... asic length, or & The time between Wei and Wei is not available. The length of the positive and negative half cycles of the power supply to the hunger is such that the power supply cycle of the lightning stable is output to the heat sink 1GG, the first month of the first month, "1B", " 2A and 3D, the heat sink 10 of the first embodiment of the present invention includes at least one coil n〇 and at least a swinging piece 120. The coil 110 is disposed on the circuit board 210 and adjacent to: The heating element 220, the line U0 and the circuit of the circuit board 210 are electrically connected to each other, and the electrical signal is transmitted between the coil 110 and the circuit board. The coil 10 of the present invention is in the form of 'J: dry disease, direct forming, etc. Disposed on the circuit board 110 receives through the circuit board 210 The source and the magnetic field are generated. The coil 110 disclosed in the present invention is electrically disposed on the circuit board 210, and is disposed on the inner side of the casing of the electronic device according to the actual heat dissipation requirement, and is generated by the power source. - The magnetic field is not limited to this embodiment. Please continue to refer to "Figure 1" and "Figure 1". The magnetic component of the present invention is a wire-wire permanent magnet that directly interacts with a magnetic field. The second driving active segment 122 is repeatedly oscillated; the _ conduction _ is electrically connected to the power source, and the magnetic flux is generated in the coil wire to interact with the linear magnetic field. The oscillating piece m is a simple elastic shape to make the pendulum elastic. The swinging member i has a good intersection activity, Ganshan, and the extension of the self-fixing section 121, and the surface area of the 22-moving section 122 is larger than the surface shape of the fixed section 12] The circuit board 210 is provided with a ceremonial machine (10), and the oscillating piece is erected on the fulcrum 130 to keep the movable section 122 above the coil 110, 3* times ^ 』this heart 1 sub-correspondence. The magnetic element i40 is disposed on the side of the active section 122 with respect to one of the coils n〇200910054, so as to interact with the coil 〇 〇 to cause the movable section 122 to push the 妒 妒 4 4 belt, κ ～ 铰 铰 铰 互 interaction , the deformation 'and in the unsupply power supply section and the direction of the coil (10) does not return to the initial state, and the magnetic force reverses and intermittently swings up and down, ^ ^ (2) the airflow being blown. The heating element 22 〇 : =: receives the power supplied by the AC power source, and _ 2 (4) is close to the coil (10). When the coil 1K) is in accordance with the current cycle of the electric current, and the maternal and miscellaneous components, the source circle (10) produces her element, please turn the === line and deform away from the direction of the righteous; the ring I]G then produces When the magnetic field is attracted by == 140, the movable section 122 of Wei Lai (10) is attracted by the coil (10), and is deformed toward the direction of the coil no, and the movable section m is repeatedly oscillated up and down by the side of the different magnetic field directions of the coil ι to generate The airflow blown toward the heating tree. In addition, the swing frequency of the wobble piece 120 is determined according to the power supply cycle of the power source, and the swing amplitude of the wobble piece 120 is determined by the magnetic field strength generated by the coil 11〇 (4)_>W2G When the swinging is performed, the swinging piece 120 does not cause an inertia due to the swing, but impinges on the housing of the electronic device 200, and is suitable for use in the electronic device 2 (8) having a small internal space. "3A" and "3B" are shown in the figure of the present invention.
