Abstract

The invention relates to a fan combination which comprises a fan and a protective cover combined on the fan, wherein the protective cover comprises a frame body and a cap body sleeved on the frame body; the frame body comprises a plurality of brackets and supporting arms, wherein the brackets are arranged on different surfaces, and the supporting arms are connected with the brackets; and the cap body is provided with a plurality of fine holes for the air flow generated by the fan to pass through. In the invention, the protective cover is arranged on the fan, thereby not only effectively preventing dust from falling into the fan, but also ensuring the security in the process of operation.

Description

technical field [0001] The invention relates to a fan combination, in particular to a fan combination with a fan protection cover. Background technique [0002] With the continuous development of the electronic industry, the operating speed and overall performance of electronic components (especially the central processing unit) are constantly improving, and the heat generated by them is also increasing. In order to make the electronic components work normally, the industry generally installs radiators on the electronic components to dissipate heat. Heat dissipation. However, the existing fans are all exposed to the air. After long-term use, the dust in the air is easy to fall on the fan blades of the fan, causing pollution to it, and it is not easy to clean, which affects the service life of the fan; The blades rotate very fast, if the operator accidentally touches the fan blades, it is easy to be injured. Contents of the invention [0003] In view of this, it is neces...
