Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation fans, in particular to an adjustable fan frame structure. Background Art

[0002] When electronic devices are in operation, the electronic components inside them generate heat. Therefore, a passive cooling unit is needed to increase the efficiency of heat dissipation to prevent the electronic components from being damaged by overheating. The cooling unit generally uses a cooling fan to generate cooling airflow to dissipate the heat.

[0003] The cooling fan is generally installed inside a fan frame, which is then installed inside the electronic device to perform heat dissipation. However, the fan blades installed inside the existing fan frame are difficult to clean and absorb dust, resulting in reduced heat dissipation effect. In addition, when the fan is working, the shaft that drives the rotation is prone to vibration, which can easily cause wear and tear, thereby reducing the service life of the shaft.
