Abstract
A heat-dissipating fan assembly is provided. The heat-dissipating fan includes a base, a axial tube, at least one coil mounted on the base, and an impeller module having an impeller, a plurality of vanes disposed on the circumferential surface of the impeller, a shaft, and a permanent magnet. The axial tube is mounted on the base, and made of a permeability material. The shaft and the permanent magnet are disposed on the same surface of the impeller. The shaft is inserted in conjunction with the axial tube. The at least one coil is used to electrically connect with a power to interact with the permanent magnet, which in turns rotates the impeller module.
Claims10
A heat dissipating fan assembly;
- comprising:
- a carrier consisting of:
- a PCB base consisting of a base and a plurality of wires, wherein the wires working as a medium for transferring electricity or signals are directly printed on the base to form the PCB base;
- an axial tube mounted on the PCB base and made of a permeability material comprising iron, wherein a portion of the PCB base under the axial tube does not have a penetrating hole;
- and
- at least one coil mounted on the PCB base;
- and
- an impeller module mounted to the axial tube, wherein the
- impeller module comprises:
- an impeller;
- a plurality of vanes disposed on the circumferential surface of the impeller;
- a shaft directly inserted into the axial tube;
- and
- a permanent magnet mounted directly around the radially outer surface of the axial tube for attracting the axial tube;
- wherein the shaft and the permanent magnet are disposed on the same surface of the impeller, and the impeller module is coupled with the PCB base via a magnet attraction between the permanent magnet arid the axial tube;
- wherein the at least one coil is electrically connected with a power via the PCB base to interact with the permanent magnet, which in turns rotates the impeller module.
