Description

Bilateral piezoelectric magnetic linkage fan 【0001】

The present invention relates to a fan, and more particularly to a bilateral piezoelectric magnetic linkage fan structure.

【0002】

In recent years, due to the rapid development of electronic products, the functions of electronic components have become increasingly powerful, and the volume of electronic components has also been gradually reduced. Therefore, the heat generation of electronic components per unit area is also increasing. The traditional cooling solution uses a heat pipe with a heat sink fin or a temperature equalizing plate, or a heat sink fin with a rotary fan to discharge the generated heat to the outside for heat dissipation.

[0003]

A heat radiating fin is mounted on a central processing unit (CPU) of the current computer host, and a rotating fan is mounted on the heat sink fin, or a temperature equalizing plate or heat conduction is installed in the central processing unit. After the temperature absorbing plate or the heat conducting block absorbs the heat source, the working fluid inside the heat pipe is transmitted to the other end of the heat pipe for heat dissipation.

[0004]

Although both the former and the latter have a good heat dissipation effect, the heat dissipation module that uses the heat pipe method to dissipate heat is bulky and easy to occupy space. In general, the space occupied by the rotary fan is relatively large, and the problem of noise after natural use is naturally derived.

Each of the plurality of interlocking blades has a top end and a bottom end, and the bottom ends are engaged in the second set of connecting grooves, and are located on two sides of the base, and each of the top ends of the linking blades is provided with a linkage magnet. When the power source causes a voltage difference between the movable end and the fixed end of the actuating portion, the actuating portion generates a continuous change in the leftward or rightward bending and continuously oscillates, and under the swing of the two main blades, the two are When the main magnet drives the interlocking magnets on the interlocking blades to oscillate, the surrounding of the interlocking blades is caused to flow, and a wind flow is formed.
