Abstract

The invention relates to a fan assembly comprising a fan and a protective hood assembled on the fan. The protective hood comprises a frame and a dustproof hood which covers the frame; the frame comprises a body and a supporting frame extending upwards from the body; and the bottom periphery of the dustproof hood is provided with an elastic element which covers the dustproof hood on the supportingframe. The dustproof hood in the invention is easily fixed on the supporting frame by the elastic element and the operation is easy and convenient.

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...
