Description

Power drive heat sink

The present invention relates to a power source driving device, and more particularly to a power source driving heat sink device having a better heat dissipation effect.

In recent years, due to advances in the electronics industry, the volume of electronic components has gradually evolved toward smaller and smaller directions. However, since the performance of the electronic components themselves has not changed, the reduction in volume has led to an increase in heat on a fixed area. Therefore, the development of an effective heat sink is currently the most important goal. Water-cooled or fan is traditionally used for heat dissipation. However, water-cooling and fan cooling methods have many drawbacks. For example, the water-cooling method is expensive, technical, and difficult to set, and the space for the fan's heat dissipation method is occupied. Large, energy-intensive, and noise-generating, so the economic efficiency is lower in the choice of heat dissipation method.

Referring to FIG. 1 , FIG. 1 is a schematic diagram of an ion flow heat dissipation device suitable for generating an ion wind. The ion flow heat dissipation device 2 is released by a first electrode 71 of a high voltage power source 70. The ions 81 are attracted by the negative ions 82 released by the other second electrode 72 of the high-voltage power source 70. Since the flow of the positive and negative ions hits the air particles 90 in the space, an ion wind phenomenon is formed. And by using the ion wind to dissipate some electronic components.

However, the ion flow heat dissipation device on the market can achieve the effect of heat dissipation, and has the advantages of small volume, fast flow speed, and low energy consumption. However, only by means of ion flow for heat dissipation, for some small-sized and high-performance microelectronic components, since it has a larger heat than the general electronic components, if the overall heat dissipation effect cannot be improved, This microelectronic component will be destroyed by excessive heat. Especially in today's electronic products, the trend of thinness and lightness, whether microelectronic components can be properly dissipated and maintain good working efficiency is also an important issue.

FIG. 3A to FIG. 3F are schematic diagrams showing the induced discharge between the first electrode member and the first metal, and FIG. 4 is a first electrode member and the first electrode. Process steps for inductive discharge between metals. The phenomenon that the first electrode member 20 of the present invention generates vibration is caused by electrical attraction and electrical repulsion of the first metal 30 by means of an inductive discharge, in order to clearly explain the mode of action of the first electrode member 20. The description will be made in order to explain the steps in the drawings, and the first electrode member 20 is equivalent to a spring member 23 and a metal member 24 in FIGS. 3A to 3F, and the spring member 23 represents the first electrode member. 20 its own flexibility. First, as shown in FIG. 3A, the first electrode member 20 and the first metal 30 fixed by a holder 21 are provided (step S1). Thereafter, as shown in FIG. 3B, the first electrode member 20 receives the positive charge supplied from the high voltage power source 10, and the metal member 24 exhibits a positively charged reaction (step S2). Then, as shown in FIG. 3C, the first metal 30 is subjected to the discharge of the positively charged first electrode member 20, and the first metal 30 generates a negative charge by mutual induction, thereby generating a positive and negative charge phase. The phenomenon of attraction. The positively charged metal component 24 is attracted to the negatively charged first metal 30, and the metal component 24 approaches the first metal 30 (step S3).

Next, as shown in FIG. 3D, the metal member 24 and the first metal 30 are attracted by the attraction of positive and negative charges, and when the first metal 30 and the first electrode member 20 are in close proximity or direct contact with each other, positive and negative charges are present at this time. It will be offset by electrical neutralization, but since the high voltage power supply 10 continues to supply a positive charge to the first electrode member 20, the metal element 24 still has a positive charge, and the metal element 24 is close to or in contact with the metal element 24. A metal 30 also has a positive charge due to induction (step S4). Then, as shown in FIG. 3E, since the metal member 24 and the first metal 30 are both positively charged, the metal member 24 is bounced off the first metal 30 due to electrical repulsion between each other and the elastic force of the spring member 23.

Thereafter, as shown in FIG. 3F, while the vibration is being applied, since the metal member 24 has moved away from the first metal 30 and the first metal 30 has no contact with the metal member 24, the positive charge of the first metal 30 is dissipated, and the metal member is eliminated. 24 will return to the state of being initially free from electrical attraction and electrical repulsion (step S6, and FIG. 3B). The metal component 24 will continue to receive the high voltage of the high voltage power supply 10 with a positive charge, causing the first metal 30 to generate a negative charge due to induction, again attracting the positively charged metal component 24 (as shown in Figure 3C). ), thereby forming a cycle of the vibration effect, so that the first electrode member 20 can continuously vibrate and enhance the flow of the ion wind to improve the heat dissipation effect of the power source driving heat dissipation device 1.

Please refer to FIG. 6. FIG. 6 is a schematic diagram of a power driving heat sink according to another embodiment.

The effect of the flow of the wind. Wherein, the second electrode member 20B has the same technical features as the first electrode member 20, and when the first electrode member 20 and the second electrode member 20B are received from the high voltage power of the high voltage power source 10, the first electrode member 20 and the second electrode are The member 20B is simultaneously subjected to the electrical attraction of the first metal 30 and its electrical repulsion, thereby forming a vibration effect equivalent to that of the embodiment. In the present embodiment, the first electrode 11 is, for example, a positive electrode, and the second electrode 12 is, for example, a negative electrode. However, those skilled in the art can also replace the first electrode 11 and the second electrode 12 with each other, and the same effect as the present embodiment can be achieved. In addition, in the embodiment, the first metal 30 is made of a composite material (as shown in FIG. 8) in which the metal and the insulating layer are bonded to prevent the induced charge in the first metal 30 from being affected by the second electrode member 20B. disappear. If the first metal 30 is made of a metal material, the distance between the first metal 30 and the first electrode member 20A needs to be equal to the distance between the first metal 30 and the second electrode member 20B.

In summary, the power supply heat sink 1 of the present invention drives the first electrode member 20 by the high voltage power source 10 compared to the conventional ion flow heat sink 2, since the first electrode member 20 and the first metal 30 Inductive action is generated between them, thereby causing the first electrode member 20 to vibrate, and enhancing the flow of the air particles 90 (shown in FIG. 1) in the space. That is to say, in addition to the ion wind generated by the conventional ion-flow heat sink 2, the power-driven heat sink 1 generates wind due to the vibration of the first electrode member 20.
