Fan structure

Abstract

A fan structure includes a base, a circuit board, a coil assembly, a fan blade and a bearing assembly. The circuit board is arranged on the base and includes an electronic component disposed thereon. The coil assembly is arranged on the base and electrically connected to the circuit board; the electronic component is arranged at an area outside of another area directly underneath the coil assembly. The internal of the fan blade includes a magnet; a bearing assembly is provided for the fan blade pivotally attached to the base therewith; the magnet is disposed at an external of the coil assembly. Therefore, the electronic component would not occupy the space in the axial direction of the motor in order to reduce the height of the fan blade without affecting air intake; the electronic component is visible from the outer appearance such that the repair of the circuit is facilitated.

These technical effects make the fan structure more efficient, cost-effective, and easier to maintain.

Problems solved by technology

As electronic information products, such as computers, are widely adapted in various fields and applications, the high demands for such products continuously drive the electronic information industry to grow and development rapidly along with greater computation speeds and increased storage capacities, which also tends to cause the generation of high temperatures during the high speed operations of the components in the electronic information products.

For example, in a computer host machine, the central processing unit (CPU) inside the machine generates most of the heat of the machine; furthermore, when the heat generated by the central processing unit gradually builds up, the performance of the machine is likely to be affected and reduced, which can cause the computer to break down or even damages to the computer if the buildup of the heat becomes significant.

Typical fan structures mostly arrange the electronic components of the circuit board to be directly underneath the coil assembly (stator) of the motor; however, with such configuration, the electronic components occupy the space in the axial direction of the motor such that the height of the fan blade cannot be reduced, which then further affects the air intake thereof.

Furthermore, by arranging the electronic components directly underneath the coil assembly (stator), the electronic components cannot be visibly seen from the outer appearance, which causes the maintenance and repair of the circuit to be difficult, in addition to that the lead wire portion needs to be additionally soldered onto the circuit board such that the additional soldering of the manufacturing process is required.
