Description

Radiating fan with enhanced stability

Technical Field

Background

With the rapid development of the intelligent home appliance industry, the CPU pursues high speed, and the heat dissipation problem derived from multifunction and miniaturization becomes more and more serious, and if the heat is not dissipated effectively, the working performance of the electronic element is greatly affected, and meanwhile, the service life of the electronic element is also shortened. Therefore, in the industry, a radiator is usually attached to the heat generating electronic component and a cooling fan is used to blow air to the radiator to generate a forced air flow so as to accelerate heat dissipation, or the cooling fan is directly used to cool the heat generating electronic component.

The traditional radiator fan, because pivot one end is connected with the flabellum, and the other end does not fix the restriction for can only rely on the intermediate position of pivot to be connected with the bearing and make the pivot rotatory, because both ends do not have fixed knot to construct and restrict, often can lead to the pivot after long-term use, especially the clearance between pivot and the bearing can be because friction is bigger and bigger. The rotation of the rotating shaft can shake more and more easily due to the fact that the rotation is restrained less and less, so that shake of the whole cooling fan is easy to occur, and the service life of the cooling fan is influenced.

The information disclosed in this background section is only for enhancement of understanding of the general background of the utility model and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art.
